The side wall of the reciprocating screw is threadedly connected to the inner wall of the sealing moving block.

The water pump transports the water on the inner wall of the water tank to the inner wall of the transport pipe through the water pump, and then transports it to the inner wall of the water spray block. The water is sprayed through the water spray block to contact with the dust in the exhaust gas and process the dust in the air, making it easier for the operator to use the device better.

[0015] (3) In the present invention, the operator connects the exhaust gas to the air inlet pipe, and the exhaust gas further passes through the inner wall of the cooling pipe 2. At this time, the coolant on the inner wall of the cooling tank will cool the side wall of the cooling pipe 2. Then the exhaust gas will be treated for the second time between the left partition and the right partition, and then it will enter the inner wall of the cooling pipe 1. At this time, the coolant on the inner wall of the cooling tank will also cool it. Finally, it will be discharged through the exhaust pipe, thereby improving the performance of the device.

[0016] (4) The present invention can effectively increase the contact time between cooling tube 1 and cooling tube 2 with the coolant through the curved design, thereby improving the cooling effect and making it easier for operators to use the device. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0024] Example 1: A preferred embodiment of a multi-flow rapid cooling chemical cooler provided by the present invention is as follows Figures 1 to 7 As shown: a multi-flow rapid cooling chemical cooler, including a cooling tank 1, A connector 3 fixedly mounted on the bottom of the cooling tank 1; A long rod 5 fixedly mounted on the side wall of the connecting member 3; and a processing assembly 4 disposed at a side position of the cooling tank 1; The processing assembly 4 includes a processing mechanism 41 installed at a side position of the cooling tank 1; A dust reduction mechanism 42 is located on the side of the cooling tank 1 and is connected to the processing mechanism 41; A cooling mechanism 43 is installed at a side position of the cooling tank 1 , and one end of the cooling mechanism 43 is located at an inner wall position of the cooling tank 1 .

[0025] The processing mechanism 41 includes a stabilizing plate 412, one end of which is fixedly connected to the top of the top plate 421, and a rectangular block 413 is fixedly installed on the other end of the stabilizing plate 412. A motor 411 is fixedly installed on the side wall of the rectangular block 413. The motor 411 movably penetrates the side wall of the rectangular block 413 through the rotating shaft at the output end and extends to the inner wall of the rectangular block 413, and a reciprocating screw 416 is installed for transmission. The other end of the reciprocating screw 416 is rotatably connected to the inner wall of the rectangular block 413 through a bearing, and a sealing moving block 417 is installed on the side wall of the reciprocating screw 416. A connecting pipe 414 is fixedly installed on the bottom of the rectangular block 413, and the other end of the connecting pipe 414 movably penetrates the side wall of the cooling tank 1 and extends to the inner wall of the cooling tank 1, and is fixedly installed with an arc plate 415.

The side wall of the reciprocating screw 416 is threadedly connected to the inner wall of the sealing moving block 417, and the side wall of the sealing moving block 417 is slidingly connected to the inner wall of the rectangular block 413.

[0027] During the specific implementation process, when the coolant is cooling the side walls of cooling tube 2 434 and cooling tube 1 432, the operator can directly turn on the motor 411, and the motor 411 drives the position of the reciprocating screw 416 to rotate through the rotating shaft at the output end. The side wall of the reciprocating screw 416 is threadedly connected to the inner wall of the sealing moving block 417.
