Description

Technical Field

[0001] This utility model relates to the field of pesticide production equipment technology, specifically to a cooling device for the production of water suspension agents. Background Technology

[0002] When pesticide suspensions are ground in a grinder, a large amount of heat is generated, requiring cooling before filling and sealing. A search revealed a Chinese patent (CN222761451U) disclosing a cooling device for the production of pesticide aqueous suspensions. This device includes an outer pipe with a water inlet, an inner pipe with the opposite flow direction to the liquid flow, and a dispensing tube between them. A transfer chamber connected to the inner pipe is located at the end of the outer pipe. This cooling device for pesticide aqueous suspension production injects cold water into the outer pipe through the inlet, redirects it through the transfer chamber, and then discharges after filling the inner pipe. The pesticide aqueous suspension enters through the dispensing tube inlet, ensuring that the suspension, surrounded by circulating water, is cooled both inside and out. This avoids the problem of reduced cooling efficiency when the diameter of the transported suspension is large. Furthermore, the cooled pesticide aqueous suspension is diverted through multiple filling tubes, and the filling tubes arranged in a circular array within the transfer chamber receive additional cooling before bottling, resulting in better cooling of the pesticide aqueous suspension.

[0003] Although this solution can ensure the cooling efficiency of the suspension in larger pipes during actual use, the combination of outer and inner pipes makes subsequent cleaning work more difficult. Utility Model Content

[0004] To address the problem of inconvenient cleaning of existing cooling devices, this invention provides a cooling device for the production of water suspension agents.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows: A cooling device for producing an aqueous suspension includes an outer tube, the bottom end of which is threadedly connected to a base. A heat exchange pipe is inserted inside the base, and the top of the heat exchange pipe extends into the interior of the outer tube. The heat exchange pipe includes a spiral tube and a vertical tube. The top end of the spiral tube communicates with the top end of the vertical tube via a connecting pipe. The vertical tube is located on the central axis of the spiral tube. The top end of the outer tube is threadedly connected to a cap for pressing down the heat exchange pipe.

[0006] Furthermore, the outer tube includes a tube body, and an inlet and an outlet are respectively provided on both sides of the outer wall of the tube body, with the inlet located at the bottom of the outlet.

[0007] The beneficial effects of adopting the above-mentioned further scheme are that the tube body provides a channel for the containment and flow of the water suspension, and the inlet and outlet on both sides of the outer wall realize the entry and discharge of the water suspension, respectively. The inlet is located at the bottom of the outlet, forming a "bottom in, top out" flow path, which allows the water suspension to fill the inside of the tube body, avoiding uneven heat exchange caused by air trapped inside the tube; at the same time, it prolongs the residence time of the water suspension in the tube body, ensuring that it is in full contact with the heat exchange pipe, improving the cooling effect, and preventing insufficiently cooled water suspension from being directly discharged, thus ensuring the cooling quality.

[0008] Furthermore, one side of the inlet and the other side of the outlet are respectively connected to a water suspension connector.

[0009] The advantage of adopting the above-mentioned further solution is that the water suspension connector can be quickly connected to the external water suspension delivery pipeline.

[0010] Furthermore, the inner wall of the tube is provided with a spiral texture, and the spiral texture has the same spiral direction as the spiral tube.

[0011] The beneficial effects of adopting the above-mentioned further solution are that the direction of the spiral texture, which is consistent with the direction of the spiral tube, can change the flow state of the water suspension inside the tube: the water suspension, which originally flows in a straight line, will form a swirling flow along the spiral texture. This swirling flow can break the boundary layer between the water suspension and the tube wall, allowing the water suspension to make more full contact with the outer wall of the heat exchange tube, and avoiding a decrease in heat exchange efficiency due to slow flow in local areas. At the same time, the swirling flow can enhance the mixing inside the water suspension, prevent temperature stratification inside the tube, ensure uniform cooling of the water suspension as a whole, and improve the quality stability of the cooled product.

[0012] Furthermore, the bottom end of the spiral tube is connected to a second right-angle bend, and the bottom end of the vertical tube is connected to a first right-angle bend.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the two sets of right-angle bends can change the flow direction of the coolant, turning the originally vertically entering and exiting coolant into a horizontal direction, which facilitates connection with external coolant delivery pipelines, reduces liquid flow resistance, and avoids the risk of blockage caused by pipe bends.

[0014] Furthermore, the base includes a hollow seat body, with a pair of first holes on each side of the top surface of the hollow seat body, and a pair of second holes on each side of the outer wall of the hollow seat body. The first right-angle bend and the second right-angle bend are respectively connected to the first hole and the second hole, and extend to the outside of the hollow seat body.

[0015] The advantages of adopting the above-mentioned further solution are that the hollow base provides a passage for the first and second right-angle bends, and the first hole on the top surface and the second hole on the outer wall precisely position the bends, ensuring that the bends do not shift after installation and avoiding interface leakage or pipeline damage due to bend displacement. The bends extend to the outside of the hollow base, facilitating connection with external coolant pipelines without requiring deep access to the base, thus improving connection convenience. Simultaneously, the hollow base protects the connection between the bends and the heat exchange pipelines, reducing damage caused by external impacts.

[0016] Furthermore, the top cap includes a cap body, the bottom end of which is connected to a spring, and the bottom end of which is connected to a pressure block. The bottom surface of the pressure block is in contact with the top surface of the spiral tube.

[0017] The beneficial effects of adopting the above-mentioned further solution are that the cap is fixed to the top of the tube body by a threaded connection, and the spring at the bottom cooperates with the pressure block to elastically press down on the heat exchange pipe. The elastic force of the spring can adapt to the installation error of the heat exchange pipe, avoiding deformation of the pipe caused by rigid pressing. The pressure block fits against the top surface of the spiral tube, increasing the pressing contact area and making the heat exchange pipe subjected to uniform force, further preventing pipe damage. The elastic pressing structure can also buffer the vibration of the device during operation, such as the vibration generated by liquid flow, to prevent the heat exchange pipe from colliding with the base and top cap due to vibration, ensuring long-term operational stability.

[0018] Furthermore, the bottom of the base is fitted with a chassis to increase the support area. The chassis includes a plate body, and the top surface of the plate body has a perforation.

[0019] The beneficial effects of adopting the above-mentioned further solution are that the chassis increases the contact area between the device and the mounting surface through the chassis body, reduces the pressure of the device on the mounting surface, avoids the mounting surface from sinking due to the weight of the device, and the perforation on the top surface of the chassis body makes it easy to fix the chassis to the mounting surface with fasteners such as bolts and expansion screws, preventing the device from shifting during operation.

[0020] Compared with the prior art, the beneficial effects of this utility model are: This water suspension production cooling device, through the combined use of a base, heat exchange pipes, and a top cap, enables efficient cooling of the water suspension while facilitating subsequent cleaning. The outer pipe provides a closed heat exchange space for the heat exchange pipes, preventing leakage of the water suspension or the introduction of external impurities, ensuring a clean cooling process. The threaded base at the bottom facilitates disassembly and assembly. When the outer wall of the heat exchange pipes and the inner wall of the outer pipes need cleaning, the base can be unscrewed to separate them, thus reducing the difficulty of cleaning. The base also provides bottom support for the heat exchange pipes, ensuring their stability during the cooling process. The spiral tube and vertical tube of the heat exchange pipeline work together to significantly increase the heat exchange area: the spiral tube extends the cooling path through the spiral structure, and the vertical tube supplements the heat exchange in the central area. The two are connected by a connecting pipe, which allows the coolant to flow fully through the entire pipeline, improving the cooling efficiency of the water suspension. In addition, the spacing between the spiral tube and the vertical tube facilitates subsequent cleaning. Furthermore, the top cap with threaded connection at the top of the outer tube not only forms a detachable structure, but can also press down on the heat exchange pipeline to prevent the heat exchange pipeline from shifting during operation and ensure structural stability.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a cooling device for the production of water suspension agents, including an outer pipe 1. The outer pipe 1 provides a closed heat exchange space for the heat exchange pipe 6, preventing leakage of the water suspension agent or the mixing of external impurities, and ensuring a clean cooling process. The bottom end of the outer pipe 1 is threadedly connected to a base 2. The heat exchange pipe 6 is inserted inside the base 2. The top of the heat exchange pipe 6 extends into the interior of the outer pipe 1. The heat exchange pipe 6 includes a spiral pipe 601 and a vertical pipe 603. The top end of the spiral pipe 601 and the top end of the vertical pipe 603 are connected by a connecting pipe 602. The vertical pipe 603 is located on the central axis of the spiral pipe 601. The base 2 threadedly connected to the bottom end of the outer pipe 1 is easy to disassemble and assemble. When the outer wall of the heat exchange pipe 6 and the inner wall of the outer pipe 1 need to be cleaned, the base 2 can be unscrewed to separate the two, thereby reducing the difficulty of cleaning. The base also provides bottom support for the heat exchange pipe to ensure its stable position during the cooling process. The spiral tube 601 of the heat exchange pipe 6 works in conjunction with the vertical tube 603 to significantly increase the heat exchange area: the spiral tube 601 extends the cooling path through the spiral structure, and the vertical tube supplements the heat exchange in the central area. The two are connected by the connecting pipe 602, so that the coolant can flow fully through the entire pipe, improving the cooling efficiency of the water suspension. In addition, there is a gap between the spiral tube 601 and the vertical tube 603, which also facilitates subsequent cleaning. The top of the outer tube 1 is threaded with a cap 4 for pressing down the heat exchange pipe 6. The cap 4 threaded at the top of the outer tube 1 forms a detachable structure and can also press down the heat exchange pipe to prevent the heat exchange pipe from shifting during the operation of the device and ensure structural stability.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] As an embodiment of this utility model, the outer tube 1 further includes a tube body 101. An inlet 102 and an outlet 103 are respectively provided on both sides of the outer wall of the tube body 101. The inlet 102 is located at the bottom of the outlet 103. The tube body 101 provides a channel for the water suspension to be contained and flow. The inlet 102 and outlet 103 on both sides of the outer wall respectively allow the water suspension to enter and exit. The inlet is located at the bottom of the outlet, forming a "bottom-in, top-out" flow path—this design allows the water suspension to fill the inside of the tube body, avoiding uneven heat exchange caused by air trapped inside the tube; at the same time, it extends the residence time of the water suspension in the tube body, ensuring sufficient contact with the heat exchange pipe 6, improving the cooling effect, preventing insufficiently cooled water suspension from being directly discharged, and ensuring cooling quality. A water suspension connector 5 is connected to one side of the inlet 102 and the outlet 103 respectively. The water suspension connector 5 can be quickly connected to an external water suspension delivery pipe.

[0027] As an embodiment of this utility model, the inner wall of the tube 101 is further provided with a spiral texture 7, the spiral direction of which is the same as that of the spiral tube 601. This alignment of the spiral direction 7 with the spiral tube 601 alters the flow state of the water suspension within the tube: the originally linearly flowing water suspension will form a swirling flow along the spiral texture. This swirling flow breaks the boundary layer between the water suspension and the tube wall, allowing the water suspension to more fully contact the outer wall of the heat exchange pipe 6, preventing a decrease in heat exchange efficiency due to slow flow in localized areas. Simultaneously, the swirling flow enhances the mixing within the water suspension, preventing temperature stratification within the tube, ensuring uniform cooling of the water suspension overall, and improving the quality stability of the cooled product.

[0028] As an embodiment of this utility model, the bottom end of the spiral tube 601 is connected to a second right-angle bend 605, and the bottom end of the vertical tube 603 is connected to a first right-angle bend 604. The two sets of right-angle bends can change the flow direction of the coolant, so that the coolant that originally entered and exited vertically becomes horizontal, which is convenient for connecting to external coolant delivery pipes, reducing liquid flow resistance, and avoiding the risk of blockage caused by pipe bending.

[0029] As an embodiment of this utility model, the base 2 further includes a hollow base body 201. A pair of first holes 202 are respectively opened on both sides of the top surface of the hollow base body 201, and a pair of second holes 203 are respectively opened on both sides of the outer wall of the hollow base body 201. The first right-angle bend 604 and the second right-angle bend 605 are respectively opened through the first holes 202 and the second holes 203, and extend to the outside of the hollow base body 201. The hollow base body 201 provides a passage for the first right-angle bend 604 and the second right-angle bend 605. The first holes 202 on the top surface and the second holes 203 on the outer wall accurately position the bends, ensuring that the bends do not shift after installation, and avoiding interface leakage or pipe damage due to pressure caused by bend displacement. The bend extends to the outside of the hollow base 201, facilitating connection with external coolant pipes without requiring deep access to the base, thus improving connection convenience. At the same time, the hollow base 201 protects the connection between the bend and the heat exchange pipe 6, reducing damage caused by external impacts.

[0030] As one embodiment of this utility model, the top cap 4 further includes a cap body 401, with a spring 402 connected to the bottom end of the cap body 401, and a pressure block 403 connected to the bottom end of the spring 402. The bottom surface of the pressure block 403 is in contact with the top surface of the spiral tube 601. The cap body 401 is fixed to the top of the tube body 101 by a threaded connection. The spring 402 at the bottom end cooperates with the pressure block 403 to elastically press down on the heat exchange pipe 6. The elastic force of the spring can adapt to the installation error of the heat exchange pipe and avoid deformation of the pipe caused by rigid pressing. The pressure block 403 is in contact with the top surface of the spiral tube 601, increasing the pressing contact area and making the heat exchange pipe subjected to uniform force, further preventing pipe damage. The elastic pressing structure can also buffer the vibration of the device during operation, such as the vibration generated by liquid flow, to prevent the heat exchange pipe 6 from colliding with the base 2 and the top cap 4 due to vibration, ensuring long-term operational stability.

[0031] As an embodiment of this utility model, the bottom end of the base 2 is fitted with a chassis 3 to increase the support area. The chassis 3 includes a disc body 301, and a through hole 302 is provided on the top surface of the disc body 301. The chassis 3 increases the contact area between the device and the mounting surface through the disc body 301, reduces the pressure of the device on the mounting surface, and avoids the mounting surface from sinking due to the weight of the device. The through hole 302 on the top surface of the disc body makes it easy to fix the chassis to the mounting surface with fasteners such as bolts and expansion screws to prevent the device from shifting during operation.

[0032] Specifically, the working principle of this water suspension production cooling device is as follows: In use, the first right-angle bend 604 and the second right-angle bend 605 of the heat exchange pipe 6 are passed through the first hole 202 and the second hole 203 of the hollow seat body 201 of the base 2 in sequence and extended to the outside. Then, the bottom end of the outer tube 1 is threaded to the base 2, so that the top of the heat exchange pipe 6 extends into the interior of the outer tube 1. Finally, the top cap 4 is threaded to the top of the outer tube 1. The spring 402 at the bottom end of the cap 401 pushes the pressure block 403 to fit against the top surface of the spiral tube 601, elastically pressing down to fix the heat exchange pipe 6 and prevent displacement. During cooling, the coolant enters the vertical pipe 603 through the first right-angle bend 604 of the external pipe, then flows into the spiral pipe 601 through the adapter pipe 602, and finally flows out from the second right-angle bend 605. At the same time, the water suspension enters the pipe body 101 of the outer pipe 1 through the water suspension connector 5 at the inlet 102, flowing along the "bottom in, top out" path. The spiral texture 7 on the inner wall of the pipe body is consistent with the spiral direction of the spiral pipe 601, causing the water suspension to form a swirling flow, breaking the boundary layer and fully contacting the outer wall of the heat exchange pipe 6, absorbing heat to achieve cooling. The cooled water suspension flows out from the water suspension connector 5 at the outlet 103. When cleaning is required, unscrew the top cap 4 and the base 2 to separate the outer pipe 1 and the heat exchange pipe 6. The distance between the spiral pipe 601 and the vertical pipe 603 is used to easily clean the inner and outer walls of both. After cleaning, reassemble for continued use. The base plate 3 at the bottom of the base 2 increases the support area through the plate body 301 and is fixed by the perforation 302 to ensure stable operation of the device.
