This device can preliminarily intercept industrial gas through a second activated carbon adsorption block, and can extract water from the water box by providing a water pump, so that the water enters the diversion box through a conduit, and is sprayed out with a nozzle to filter the gas, and the gas is recovered through the industrial gas recovery pipe. The first activated carbon adsorption block can filter the water as it flows downward, adsorb large particles in the water, filter the water, and allow the water to be recycled, thereby solving the problem that the sprayed water is difficult to filter and reuse, resulting in a large amount of water being consumed in the process of recovering industrial gas.

[0004] This patent solves the problem that the sprayed water is difficult to filter and reuse, resulting in a large amount of water consumption in the process of recovering industrial gases. However, the existing device does not filter the particles inside the gas before recovering the gas, which affects the subsequent filtration effect. Therefore, we propose a new type of polycarboxylic acid water reducer gas recovery device. Utility Model Content

[0009] Furthermore, the plug block and the socket form a plug-in connection, and the filter screen and the slide groove form a sliding connection.

[0010] Furthermore, the outer surfaces of both sides of the filter screen are in contact with the inner walls of both sides of the chute.

[0011] Furthermore, a monitoring component is provided on one side of the air inlet pipe, and the monitoring component includes a monitoring meter, and a flow sensor is connected to the bottom of the monitoring meter.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

DETAILED DESCRIPTION

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figure 1 - Figure 3As shown, the utility model provides a polycarboxylate water reducer gas recovery device, including a recovery box 1, an air inlet pipe 2 is connected to the top of one side of the recovery box 1, an air outlet pipe 3 is connected to the bottom of one side of the recovery box 1, a primary filter assembly 4 is provided on the surface of the air inlet pipe 2, the primary filter assembly 4 includes a filter box 401, a chute 402 is provided inside the filter box 401, a filter screen 403 is provided inside the chute 402, and a plug hole 404 is provided on the outer surface of both sides of the filter screen 403, a fixing frame 405 is connected to the rear end surface of the filter box 401, a screw groove 406 is provided inside the fixing frame 405, a bidirectional screw 407 is inserted into the screw groove 406, one end of the bidirectional screw 407 is connected to a bearing 408, and the bidirectional screw 407 is provided with a screw hole 404. The other end is connected to a handle 409, and two groups of moving blocks 410 are symmetrically arranged on the surface of the bidirectional screw 407. Threaded holes 411 are provided inside the two groups of moving blocks 410, and plug blocks 412 are connected inside the two groups of moving blocks 410. The bidirectional screw 407 and the bearing 408 are rotated in connection, and the bidirectional screw 407 and the handle 409 are fixedly connected. The moving block 410 is threadedly connected to the bidirectional screw 407 through the threaded hole 411. The position and size of the plug block 412 match the position and size of the socket 404, and the plug-in connection is formed between the plug block 412 and the socket 404. The filter screen 403 and the slide groove 402 are in sliding connection, and the outer surfaces on both sides of the filter screen 403 are in contact with the inner walls on both sides of the slide groove 402.

[0023] The effect achieved by the entire embodiment 1 is that when the polycarboxylate water-reducing agent gas enters the recovery box 1, it will first be filtered through the filter 403 to preliminarily filter out large particles of impurities and some harmful substances in the gas, and then enter the recovery box 1 for subsequent treatment. When there are many impurities on the surface of the filter 403, the handle 409 can be rotated in the reverse direction to drive the bidirectional screw 407 to rotate in the reverse direction, so that the bidirectional screw 407 can be reversely threadedly connected with the two sets of moving blocks 410 through the threaded holes 411, so that the two sets of moving blocks 410 can move to both sides at the same time. When the moving blocks 410 move, they will also drive the plug block 412 to be pulled out of the socket 404. When the filter 403 is removed from the chute 402 and cleaned, and the impurities on the surface of the filter 403 are cleaned, the filter 403 can be inserted into the chute 402 again, and then the handle 409 is rotated forward to drive the bidirectional screw 407 to rotate forward, so that the bidirectional screw 407 can drive the two sets of moving blocks 410 to push the two sets of plug-in blocks 412 to move inward at the same time through the forward thread rotation, and insert them into the socket 404 for fixation, so that the large particles of impurities and some harmful substances in the gas can be filtered through the filter 403 in the filter box 401, which helps to reduce the burden on subsequent professional equipment and improve the stability and efficiency of the entire filtration system.

[0024] Example 2, as Figure 1 and Figure 4 As shown, a monitoring component 5 is provided on one side of the air inlet pipe 2 . The monitoring component 5 includes a monitoring meter 501 . A flow sensor 502 is connected to the bottom of the monitoring meter 501 .

[0025] The effect achieved by the entire embodiment 2 is that the gas flow in the intake pipe 2 can be monitored in real time through the flow sensor 502. When a large amount of impurities are adsorbed on the surface of the filter 403, it can be observed through the monitoring meter 501. After that, the filter 403 can be taken out for use to prevent excessive impurities in the filter 403 from affecting the gas recovery efficiency.

[0026] Working principle: When gas recovery is being carried out, large particles of impurities and some harmful substances in the gas will first be filtered through the filter 403 in the filter box 401, which helps to reduce the burden on subsequent professional equipment and improve the stability and efficiency of the entire filtration system. The gas flow can be observed through the monitoring meter 501. When the air intake in the intake pipe 2 is small, the filter 403 can be removed for cleaning to avoid affecting the gas recovery efficiency.
