[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1-4 As shown, a cooling device for the production of pesticide water suspension comprises an outer tube 1 provided with a water inlet, an inner tube 11 is provided in the outer tube 1 in the opposite direction of the liquid flow, and a reagent tube 2 is provided between the two;

[0029] The outer tube 1 has a transfer cavity 12 at its end connected to the inner tube 11 , and the dosage tube 2 is connected to a plurality of filling tubes 21 in the transfer cavity 12 .

[0030] Specifically, the outer tube 1 and the inner tube 11 are cooling pipes in the cooling system of the pesticide aqueous suspension, and there are multiple of them, which are used to improve the cooling efficiency of the pesticide aqueous suspension. The outer tube 1, the agent tube 2 and the inner tube 11 have three cavities in the cross section, which are used to transport cold water, the pesticide aqueous suspension ( Figure 2 The filling tube 21 is extended to the outside of the outer tube 1 , so that the automated canning equipment connects the filling hose and the filling tube 21 .

[0031] Cold water is injected into the outer tube 1 through the water inlet, redirected into the inner tube 11 through the transfer chamber 12, discharged after filling the inner tube 11, and then injected into the outer tube 1 after the water is cooled by the rotary system in the cooling equipment (existing technology, which will not be described here), and the pesticide suspension enters from the inlet of the agent tube 2, so that the suspension surrounded by the positive and reverse circulating water can be cooled both inside and outside, avoiding the problem of reduced cooling efficiency when the diameter of the transported suspension is large, and the cooled pesticide suspension is diverted through multiple filling pipes 21, so that the automated canning equipment can can more medicine bottles, and the filling pipes 21 arranged in a circular array in the transfer chamber 12 are subjected to additional cooling treatment before canning, so that the cooling effect of the pesticide suspension is better.

[0032] As an embodiment further provided by the present invention, a plurality of brackets 3 are arranged between the inner tube 11 and the agent tube 2 , and blades 35 arranged in a circumferential array are rotatably arranged on the brackets 3 .

[0033] Specifically, the blade 35 is hollow, and a plurality of filter holes are formed on its end surface, so that the blade 35 can intercept and store dirt in the pesticide aqueous suspension, so that the canned pesticide aqueous suspension is more in compliance with the standard.

[0034] The blades 35 are in the cavity where the pesticide aqueous suspension is transported, so that the multiple blades 35 are impacted and rotated, and the transported pesticide aqueous suspension is stirred and heated more evenly, so as to improve the heat transfer efficiency and the cooling effect.

[0035] As another embodiment further provided by the present invention, the bracket 3 is provided with a plurality of partitions 31 fixedly mounted on the inner wall of the agent tube 2 .

[0036] The bracket 3 is fixed in the cavity for conveying the pesticide suspension by using a plurality of partitions 31, so that the blades 35 are more stable when stirring the pesticide suspension, ensuring that the pesticide suspension is evenly dispersed in the cavity, thereby improving the cooling effect.

[0037] As another embodiment further provided by the present invention, an elastic member 32 is disposed on the bracket 3 , a ring frame 33 is rotatably disposed on the end of the elastic member 32 , and the blades 35 move radially on the ring frame 33 .

[0038] Specifically, the elastic member 32 is a spring, the ring frame 33 slides on the side wall of the inner tube 11, and a plurality of notches are provided on the outer ring of the ring frame 33. The blades 35 move in the notches, and a predetermined distance is maintained between the edge of the blade 35 and the inner wall of the agent tube 2.

[0039] The ring frame 33 provides the blade 35 with a rotation condition, and the elastic member 32 can be compressed and deformed by the ring frame 33 , and the prerequisite is that the flow velocity in the agent tube 2 increases, so that the axially moving ring frame 33 changes the stirring position in the agent tube 2 .

[0040] As another embodiment further provided by the present invention, the ring frame 33 moves close to the bracket 3 and compresses the elastic member 32 to deform, so that the blades 35 cooperate with the partition plate 31 to prevent the agent pipe 2 from draining liquid.

[0041] Specifically, the bracket 3 is provided with a groove for accommodating the elastic member 32 to be fully compressed, so that the plurality of blades 35 and the partition plate 31 can maintain a predetermined distance.

[0042] The flow rate in the agent tube 2 is increased by using a pesticide suspension discharge device (existing technology, which will not be described in detail here), so that the blades 35 compress the elastic member 32 through the ring frame 33, and the minimum distance between the blades 35 and the partition 31 is maintained. Since the rotating blades 35 will block the gap between every two partitions 31, the flow rate of the pesticide suspension flowing in the agent tube 2 is reduced to a minimum, and a water hammer effect is formed in the agent tube 2, so that the vibration generated will shake off the pesticide suspension particles attached to the inner wall of the agent tube 2, thereby reducing the problem of blockage in the agent tube 2. Moreover, since the blades 35 on the multiple ring frames 33 will gradually increase the flow rate of the pesticide suspension, when the multiple elastic members 32 are compressed in turn, the water hammer effect will gradually be transmitted in the agent tube 2, so that the entire agent tube 2 can be subjected to vibration treatment.

[0043] As another embodiment further provided by the utility model, a movable seat 34 is provided on the blade 35, and a plurality of trigger blocks 36 are provided on the bracket 3;

[0044] The trigger block 36 is in contact with the movable seat 34 , so that the edge of the blade 35 is in contact with the inner wall of the agent tube 2 .

[0045] Specifically, the movable seat 34 slides in the notch on the ring frame 33, and the movable seat 34 has a slider and a tension spring, and the slider has a damping, so that the movable seat 34 maintains a slow speed when resetting. The sliding and force storage methods are existing technologies and will not be described in detail here.

[0046] Furthermore, the end of the trigger block 36 faces the ring frame 33 , and the end of the trigger block 36 also has an inclined surface, which facilitates the sliding fit between the inclined surface and the movable seat 34 .

[0047] When the ring frame 33 gradually fits the bracket 3, the inclined surface on the trigger block 36 slides against the movable seat 34, so that the multiple movable seats 34 move in a radial diffusion manner until the edge of the blade 35 abuts against the inner wall of the agent tube 2. When the flow rate of the pesticide aqueous suspension in the agent tube 2 decreases, the elastic member 32 drives the ring frame 33 to reset, so that the edges of the multiple blades 35 scrape the inner wall of the agent tube 2, so as to achieve the purpose of removing particles attached to the inner wall of the agent tube 2, and the scraped particles will continue to be stirred by the rotation of the blade 35, and some dirt will also enter from the filter holes on the blade 35 and be stored.

[0048] As another embodiment further provided by the utility model, the outer tube 1 is connected to a liquid tank 4 , and the liquid tank 4 is provided with an inner tube 41 connected to the agent tube 2 .

[0049] As the flow rate of the pesticide suspension in the agent tube 2 increases, along with the increase in flow rate, and before the water hammer effect occurs, the excess pesticide suspension enters the inner cylinder 41 for storage, so that the water in the liquid tank 4 cools down this part of the pesticide suspension, thereby reducing the problem of excessive temperature of the discharged pesticide suspension.

[0050] As another embodiment further provided by the present invention, a plug 42 is slidably disposed in the inner cylinder 41 .

[0051] Specifically, a rubber ring is fixedly sleeved on the plug 42, and the rubber ring is slidably matched with the inner wall of the inner tube 41. A plurality of slots are opened at the end of the inner tube 41 to allow the cold water in the liquid tank 4 to enter the plug 42 of the inner tube 41 from the slots, and a telescopic rod is fixedly installed between the plug 42 and the inner wall of the liquid tank 4.

[0052] The plug 42 is located at the end of the inner tube 41 under the action of its own gravity and water pressure, so that the pesticide aqueous suspension can be normally cooled in the agent tube 2.

[0053] As another embodiment further provided by the present invention, a liquid discharge port 43 is provided at the port of the inner cylinder 41 .

[0054] Specifically, the cross section of the liquid discharge port 43 is inverted conical, so that the plug 42 can be easily limited by the liquid discharge port 43 .

[0055] The pesticide aqueous suspension in the agent tube 2 enters the inner cylinder 41 from the drain port 43 , and the drain port 43 can effectively reduce the amount of pesticide aqueous suspension entering the inner cylinder 41 under normal circumstances.

[0056] As another embodiment further provided by the present invention, the drain port 43 is provided with a valve.

[0057] Specifically, the valve is hinged to the smaller bottom surface of the drain port 43, and the valve is prior art, which will not be described in detail here.

[0058] By increasing the pressure in the agent tube 2, the excess pesticide water suspension opens the valve and enters the inner tube 41 from the discharge port 43, so that the plug 42 slides upward due to the increased pressure below, and the pesticide water suspension gradually filling the inner tube 41 is cooled by the cooling water with reduced flow rate in the liquid tank 4, and the liquid tank 4 also causes a certain water hammer effect in the outer tube 1, so that the inside and outside of the agent tube 2 are vibrated, and the treatment effect on attached particles is increased. When the flow rate in the agent tube 2 is reduced, the water flow rate in the outer tube 1 is increased, so that the plug 42 is driven by the water pressure and reset to the discharge port 43.

[0059] Working principle: cold water is injected into the outer tube 1 through the water inlet, redirected into the inner tube 11 through the transfer chamber 12, and discharged after filling the inner tube 11. The pesticide suspension enters from the entrance of the agent tube 2, so that the suspension surrounded by the positive and reverse circulating water can be cooled both inside and outside, and the cooled pesticide suspension is diverted through multiple filling tubes 21, and the filling tubes 21 arranged in a circumferential array in the transfer chamber 12 are subjected to additional cooling treatment before canning, increasing the flow rate in the agent tube 2, so that the blades 35 compress the elastic member 32 through the ring frame 33, and keep the minimum distance between the blades 35 and the partition 31, and because the rotating blades 35 will block the gap between every two partitions 31, the flow rate of the pesticide suspension flowing in the agent tube 2 is reduced to a minimum, and a water hammer effect is formed in the agent tube 2, so that the vibration generated will shake off the pesticide suspension particles attached to the inner wall of the agent tube 2, reducing the problem of blockage in the agent tube 2.

[0060] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
