In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the utility model. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the described embodiments of the present invention belong to the protection scope of the present invention.

The utility model provides a catalytic material preparation device for improving the absorption rate of waste gas, which comprises multiple sets of storage tanks 1 each containing two in number and heating and stirring equipment 12 arranged below them;

A mixing box 2 is communicated between the storage tank 1 and the heating and stirring equipment 12 through a pipeline, and the mixing box 2 is provided with a batching unit 3 capable of controlling the proportion of materials through a movement stroke. The mixing box 2 An electric push rod 4 for providing power for the batching unit 3 is fixedly connected to the outer wall of the body, and a sealing door 5 for sealing the material storage tank 1 is rotatably connected to the inner wall of the connection between the mixing box 2 and the material storage tank 1;

By adopting the above-mentioned technical scheme, as shown in Figure 1, multiple groups of storage tanks 1 are divided into _G1 tanks from left to right: sodium hydroxide and water, _G2 tanks: deionized water and dimethyl sulfone, _G3 tanks Tank: Salt of filtered metal Cu as active component and salt of noble metal Pt as co-catalyst, G ₄ tanks: catalyst support precursor (pseudoboehmite and cerium nitrate), each group of storage tanks 1 includes tanks a and b number tank;

First, in the initial state, the sealing door 5 seals the storage tank 1, and the sealing process for the storage tank 1 is:

The staff controls the output end of the electric push rod 4 to stretch out according to the controller, and drives the components in the batching unit 3 to work forward. In the movement track of the forward movement of the components in the batching unit 3, first close the airtight door 5 of the b tank. , and then close the airtight door 5 of tank a to complete the sealing of storage tank 1;

Secondly, various raw materials are stored in corresponding storage tanks 1 according to their respective chemical properties;

Therefore, the staff only need to control the working stroke of the No. 1 sleeve rod 37 through the electric push rod 4, and can adjust the continuous opening time of the airtight door 5 of each material storage tank 1, and then adjust the proportion of each ingredient, without the need for the staff to weigh repeatedly. amount, thereby improving the work efficiency of catalytic material preparation;

Simultaneously, due to the screw transmission connection between the rotating disk 33 and the screw rod 34, therefore, the rotating disk 33 rotates at the same time during the forward linear movement and the reverse linear movement under the drive of the electric push rod 4, and due to the rotation The disk 33 is composed of two annular bodies 331 and a plurality of blades 332, so the rotating disk 33 can stir the raw materials entering the mixing box 2 when rotating, improve the mixing effect of the raw materials, and realize the balance between stirring and controlling the proportion of raw materials. structural integration;

And, considering that the No. 1 cover rod 37 and the No. 2 cover rod 38 will not occupy the larger space of the mixing box 2, the No. 1 cover rod 37 and the No. 2 cover rod 38 are arranged in the form of telescopic rods, but the above-mentioned telescopic In the form of a rod, when the distance between the airtight door 5 of tank a and the door 5 of tank b is long, the rod 37 of the first set moves forward and will break away from the tank b when it approaches the seal door 5 of tank a The airtight door 5 is therefore provided with a compensating assembly 6 in the No. 2 sleeve rod 38;

When the distance between the airtight door 5 of No. a tank and the airtight door 5 of No. b tank is longer, the No. 1 sleeve rod 37 moves forward and breaks away from the airtight door 5 of No. b tank in the process of approaching the airtight door 5 of No. a tank At this time, the extrusion force that the No. 1 spring 61 is subjected to disappears, recovers elastic deformation, and drives the compensating block 63 to eject from the through groove 62, and compensates for the supporting effect of the No. 1 sleeve rod 37 on the sealed door 5 of the b tank, improving the safety of the device. practical performance;
