Description

Technical Field

[0001] The utility model relates to the technical field related to agriculture, and more specifically to a circulating cooling structure for the production of pesticide intermediates. Background Art

[0002] Pesticide intermediates are the intermediate components in the target products of pesticide production. Since most pesticides are large molecular organic substances, their production process is complicated and the temperatures required for each reaction process are different. The intermediates need to be left to cool to the corresponding temperature before the next step of production can be carried out.

[0003] The existing patent is a cooling structure for the production of pesticide intermediates. The patent authorization number CN214808596U solves the problems of lack of cooling process and lack of layer-by-layer purification of intermediates in the existing pesticide intermediate production process by setting an external cooling cylinder, a top sealing disk and an extraction cylinder.

[0004] However, in patent authorization number CN214808596U, a cooling input pipe is sleeved inside the cooling input port, and the cooling input pipe transports the pesticide intermediates to be cooled to the inner cooling cylinder for cooling. The top sealing plate transports the pesticide intermediates to be cooled to the inner cooling cylinder for cooling through the cooling input pipe on the bottom sealing plate. The pesticide intermediates cooled in the inner cooling cylinder are transported to the extraction cylinder through the cooling output pipe fixed on the top sealing plate. Since the pesticide intermediates continue to pass through the inner cooling cylinder, the temperature of the inner cooling cylinder will gradually rise, and the pesticide intermediates in the rear section cannot be cooled well, resulting in unsatisfactory cooling effect on the intermediates. Therefore, we propose a circulating cooling structure for pesticide intermediate production to solve the above-mentioned problems. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a circulating cooling structure for the production of pesticide intermediates, which can utilize a first circulating pump to circulate and cool the pesticide intermediates in a cooling pool, so that the pesticide intermediates in the rear section can be well cooled, thereby improving the cooling effect.

[0006] To solve the above problems, the utility model adopts the following technical solutions.

[0007] A circulating cooling structure for the production of pesticide intermediates, comprising a cooling pool, an output pipe and an input pipe connected to the cooling pool, and a stop valve installed at the output pipe, a main pipe is installed on the top of the cooling pool, a branch pipe is installed at a radial position of the main pipe, and a nozzle is installed at the bottom of the branch pipe;

[0008] A filler is installed below the nozzle;

[0009] The root of the cooling pool is conductively connected to a circulation pipe, and the top of the circulation pipe is conductively connected to the main pipe. The bottom of the circulation pipe is installed with a first circulation pump, and the output end of the first circulation pump corresponds to the main pipe.

[0010] An outer sleeve is installed on the outer side of the cooling pool, a fan is installed on the top of the outer sleeve, and air inlets are symmetrically opened on the side wall of the outer sleeve.

[0011] Furthermore, a heat exchange pipe is laid at the bottom of the cooling pool, and the heat exchange pipe is arranged in a continuous S-shaped configuration at the inner side of the cooling pool;

[0012] The output end and the input end of the heat exchange tube both extend to the outside of the outer sleeve;

[0013] The heat exchange tube is made of copper.

[0014] Furthermore, a second circulation pump is installed at the input end of the heat exchange tube, and the output end of the second circulation pump corresponds to the cooling pool.

[0015] Furthermore, a water pool is provided on one side of the outer sleeve, and the output end and the input end of the heat exchange tube are both conductively connected to the water pool.

[0016] Furthermore, a liquid filling port is provided on the top of the water pool.

[0017] Furthermore, a plurality of branch pipes are equidistantly arranged at axial positions of the main pipe;

[0018] A plurality of the nozzles are equidistantly arranged at axial positions of the branch pipe.

[0019] Furthermore, the top end of the outer sleeve is arranged in an open structure.

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] (1) In this scheme, the intermediate in the cooling pool is pumped into the main pipe through the circulation pipe by turning on the first circulation pump, and the intermediate is evenly sprayed and distributed to the filler area by the nozzle installed at the branch pipe. The intermediate forms a liquid film on the filler, and the air is sucked into the inner side of the outer sleeve through the air inlet by the fan, thereby accelerating the flow rate of air at the filler. When the air flows through the filler, the air and the liquid film formed by the intermediate exchange heat, thereby reducing the temperature of the intermediate. The cooled intermediate drips to the bottom of the cooling pool and circulates in this way, so that the pesticide intermediate in the later stage can be well cooled, thereby improving the cooling effect.

[0022] (2) In this scheme, the heat exchange tube is immersed in the pesticide intermediate at the bottom of the inner cavity of the cooling pool, and the cooling water in the pool is transported to the heat exchange tube by the second circulation pump. The heat of the pesticide intermediate is transferred to the cooling water by the heat exchange tube, and the heat is taken away by the flowing cooling water, which can accelerate the cooling efficiency of the pesticide intermediate.

The intermediate forms a liquid film on the filler 7, and the air is sucked into the inner side of the outer sleeve 10 through the air inlet 12 by the fan 11, thereby accelerating the flow speed of the air at the filler 7. When the air flows through the filler 7, the air and the liquid film formed by the intermediate exchange heat, thereby reducing the temperature of the intermediate. The cooled intermediate drips to the bottom of the cooling pool 1 and circulates in this way, so that the pesticide intermediate in the later stage can be well cooled, thereby improving the cooling effect.

When the air flows through the filler 7, the air and the liquid film formed by the intermediate exchange heat, thereby reducing the temperature of the intermediate. The cooled intermediate drips to the bottom of the cooling pool 1 and circulates in this way.
