Description

Technical Field

[0001] This utility model relates to the technical field of pesticides, and in particular to a pesticide suspension cooling device. Background Technology

[0002] When pesticide suspensions are ground in a grinder, a heating device needs to be installed at the inlet of the grinder to heat the raw materials. Also, the grinding process generates a lot of heat after the raw materials enter the grinding chamber, so it is necessary to cool them down.

[0003] Chinese utility model patent with publication number CN220380066U discloses a cooling device for the production of pesticide water suspensions. This cooling device includes an adjustment mechanism with a mounting plate fixedly connected to the right side wall of a fixed base plate. A first motor is mounted on the right side wall of the mounting plate. Starting the first motor causes the output rod to drive two sets of eccentric wheels to rotate. Because the two sets of eccentric wheels have opposite eccentricities, they press against the left and right sides of the bottom of the cooling chamber during rotation. A rigid spring further causes the cooling chamber to sway left and right. Starting a second motor then causes a stirring plate to rotate and stir the material. Through the cooling mechanism, the material is thoroughly cooled, and the stirring process is also achieved.

[0004] However, the aforementioned cooling equipment requires shaking the tank during operation, resulting in poor structural stability. Furthermore, the aforementioned cooling equipment is not convenient for continuous feeding and discharging cooling processes. After a large amount of pesticide suspension is loaded into the cooling tank, the cooling time will be prolonged and the uniformity of cooling cannot be guaranteed. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a pesticide suspension cooling and temperature reduction device with good structural stability, capable of continuous feeding and discharging, and good practicality.

[0006] This utility model discloses a pesticide suspension cooling and temperature reduction device, comprising a cooling box, a cooling water jacket, and a cooler. The cooling box has a cooling chamber inside, and a discharge port is installed on the outer wall of the cooling box. The cooling water jacket is fitted onto the outer wall of the cooling box. It also includes a feeding pipe, a fluidized bed hopper, spiral blades, a cylinder, and a drive mechanism. The fluidized bed hopper is installed at the bottom of the cooling chamber of the cooling box. An air supply cap is installed at the air outlet of the cooler, located at the center of the bottom of the fluidized bed hopper. The feeding pipe is vertically installed in the center of the cooling box, with its output end extending into the fluidized bed hopper. The spiral blades are rotatably installed in the cooling chamber of the cooling box. The spiral blades are located between the inner wall of the cooling box and the outer wall of the fluidized bed hopper. A cylinder is installed at the upper center of the spiral blades. The fluidized bed hopper and the cylinder are arranged vertically opposite each other, with a gap between them. The drive mechanism is mounted on the cooling box and drives the cylinder to rotate. An air vent is located at the top of the cooling box, between the cylinder and the feed pipe. During operation, the cooling water jacket is connected to an external cooling water system, allowing the cooling water jacket to cool the cooling box. The drive mechanism can be a gear drive mechanism, chain drive mechanism, etc., which drives the cylinder to rotate, and the cylinder drives the spiral blades to rotate. (Pesticide suspension) The powder is added to the center bottom of the fluidized bed hopper through the feed pipe. A cool air blower evenly supplies cold air to the bottom of the fluidized bed hopper through the air supply cap. The cold air blows the pesticide suspension powder upwards, creating a fluidized bed state and ensuring full contact between the pesticide suspension powder and the cold air for cooling. As the pesticide suspension powder is conveyed through the feed pipe, the excess powder overflows from the fluidized bed hopper and enters the spiral blades between the fluidized bed hopper and the inner wall of the cooling chamber. The rotating spiral blades lift the pesticide suspension powder upwards, during which the powder comes into contact with the low-temperature outer wall of the cooling chamber. The pesticide suspension powder is cooled by contact cooling. After reaching the top of the cooling box, the cooled pesticide suspension powder is discharged through the outlet. During this process, the pesticide suspension powder blown by the cold air falls onto the spiral blades through the gap between the fluidized bed hopper and the cylinder. The cold air discharged from the fluidized bed hopper is discharged from the cooling box through the air outlet at the top of the cooling box and input into the exhaust gas treatment system. Compared with the existing technology, the cooling box will not shake, has good structural stability, and can carry out continuous feeding and discharging cooling process. It avoids the problems of prolonged cooling time and poor cooling uniformity when a large amount of pesticide suspension is loaded into the cooling box, and has good practicality.

[0007] Preferably, it also includes a guide cone, which is installed below the output end of the feed pipe. The guide cone is conical, with its edge extending outside the output end of the feed pipe and its tip pointing downwards. The guide cone blocks the cold air output from the air supply cap and guides it to the edge, preventing cold air from rushing into the feed pipe and interfering with the feeding of pesticide suspension powder, thus improving the reliability of feeding.

[0008] Preferably, the vertical cross-section of the spiral blade is inclined, with the outer edge of the vertical cross-section lower than the inner edge. By setting the spiral blade with an outwardly inclined vertical cross-section, the pesticide suspension powder on the spiral blade is concentrated towards the inner wall of the cooling box, preventing the pesticide suspension powder from falling into the fluidized bed hopper, and increasing the contact area between the pesticide suspension powder and the cooling box, thereby improving the cooling effect.

[0009] Preferably, it also includes a filter plate, which is installed on the upper outer wall of the feeding pipe, and the outer wall of the feeding pipe slides in contact with the inner wall of the cylinder; the filter plate is used to intercept pesticide suspension powder that rises with the cold air, so as to avoid the spread of pesticide suspension powder and cause pollution and toxicity.

[0010] Preferably, it also includes a brush plate and brush bristles. The brush plate is installed on the inner wall of the cylinder and is located above the filter plate. A large number of brush bristles are installed on the brush plate, and the lower end of the brush bristles makes contact with the filter plate. When the cylinder rotates, it drives the brush plate to rotate, so that the brush plate drives the brush bristles to brush the filter holes of the filter plate and clear the blocked filter holes.

[0011] Preferably, the assembly also includes a brush roller, brush bristles, a bevel gear, and a bevel gear ring. The brush roller is rotatably mounted on the inner wall of the cylinder, and multiple brush bristles are circumferentially mounted on the outer wall of the brush roller. The lower ends of the brush bristles contact the filter plate with a brushing motion. A bevel gear is concentrically mounted on the inner end of the brush roller, and the bevel gear meshes with the bevel gear ring, which is concentrically mounted on the outer wall of the feeding pipe. When the cylinder rotates, it drives the brush roller to rotate around the feeding pipe. The meshing of the bevel gear and the bevel gear ring causes the brush roller to rotate, which in turn drives the brush bristles to brush the filter holes of the filter plate and clear any blockages.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: During operation, the cooling water jacket is connected to an external cooling water system, allowing the cooling water jacket to cool the cooling box. The drive mechanism is a gear transmission mechanism, chain transmission mechanism, etc. The drive mechanism drives the cylinder to rotate, and the cylinder drives the spiral blades to rotate. The pesticide suspension powder is added to the center bottom of the fluidized bed hopper through the feeding pipe. The cold air fan evenly delivers cold air to the bottom of the fluidized bed hopper through the air supply cap. The cold air blows the pesticide suspension powder from bottom to top, making the pesticide suspension powder a fluidized bed state, allowing the pesticide suspension powder to fully contact the cold air for air cooling. As the pesticide suspension powder is conveyed in the feeding pipe, the pesticide suspension powder overflowing from the fluidized bed hopper enters the inner wall of the fluidized bed hopper and the cooling box. On the rotating helical blades, the pesticide suspension powder is lifted upwards. During this lifting process, the pesticide suspension powder comes into contact with the low-temperature cooling box outer wall for cooling. After reaching the top of the cooling box, the cooled pesticide suspension powder is discharged through the outlet. In this process, the pesticide suspension powder blown by the cold air falls onto the helical blades through the gap between the fluidized bed hopper and the cylinder. The cold air discharged from the fluidized bed hopper is discharged from the cooling box through the air outlet at the top of the cooling box and input into the exhaust gas treatment system. Compared with the existing technology, the cooling box does not shake, has good structural stability, and can carry out continuous feeding and discharging cooling processes. It avoids the problems of prolonged cooling time and poor cooling uniformity when a large amount of pesticide suspension is loaded into the cooling box, and has good practicality.

Detailed Implementation

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0022] Example 1

[0023] like Figures 1 to 6 As shown, a pesticide suspension cooling device includes a cooling box 1, a cooling water jacket 2, and a cooler 3. The cooling box 1 has a cooling chamber inside, and a discharge port is installed on the outer wall of the cooling box 1. The cooling water jacket 2 is fitted onto the outer wall of the cooling box 1. It also includes a feeding pipe 18, a fluidized bed hopper 4, spiral blades 5, a cylinder 6, and a drive mechanism 7. The fluidized bed hopper 4 is installed at the bottom of the cooling chamber of the cooling box 1. An air supply cap 8 is installed at the air outlet of the cooler 3, located at the center of the bottom of the fluidized bed hopper 4. The feeding pipe 18 is vertically installed in the center of the cooling box 1, with its output end extending into the fluidized bed hopper 4. The spiral blades 5 are rotatably installed in the cooling chamber of the cooling box 1. The blade 5 is located between the inner wall of the cooling box 1 and the outer wall of the fluidized bed hopper 4. The cylinder 6 is installed at the upper center of the spiral blade 5. The fluidized bed hopper 4 and the cylinder 6 are arranged vertically opposite each other, and a gap is provided between the fluidized bed hopper 4 and the cylinder 6. The drive mechanism 7 is installed on the cooling box 1 and drives the cylinder 6 to rotate. The top of the cooling box 1 is provided with an air outlet, which is located between the cylinder 6 and the feed pipe 18. It also includes a guide cone 9, which is installed below the output end of the feed pipe 18. The guide cone 9 is conical, and the edge of the guide cone 9 extends outside the output end of the feed pipe 18, with the tip of the guide cone 9 pointing downward. The vertical section of the spiral blade 5 is inclined, and the outer edge of the vertical section is lower than the inner edge.

[0024] During operation, the cooling water jacket 2 is connected to an external cooling water system, allowing it to cool the cooling tank 1. The drive mechanism 7 is a gear transmission mechanism, chain transmission mechanism, etc., which drives the cylinder 6 to rotate. The cylinder 6 drives the spiral blades 5 to rotate. The pesticide suspension powder is added to the center bottom of the fluidized bed hopper 4 through the feed pipe 18. The air cooler 3 evenly delivers cold air to the bottom of the fluidized bed hopper 4 through the air supply cap 8. The cold air blows the pesticide suspension powder from bottom to top, making the pesticide suspension powder a fluidized bed state, allowing the pesticide suspension powder to fully contact the cold air for air cooling. As the pesticide suspension powder is conveyed in the feed pipe 18, the pesticide suspension powder overflowing from the fluidized bed hopper 4 enters the spiral blades between the fluidized bed hopper 4 and the inner wall of the cooling tank 1. On plate 5, the rotating spiral blades 5 lift the pesticide suspension powder upwards. During the lifting process, the pesticide suspension powder comes into contact with the low-temperature cooling box 1 for cooling. After reaching the top of the cooling box 1, the cooled pesticide suspension powder is discharged through the outlet. In this process, the pesticide suspension powder blown by the cold air falls onto the spiral blades 5 through the gap between the fluidized bed hopper 4 and the cylinder 6. The cold air discharged from the fluidized bed hopper 4 is discharged from the cooling box 1 through the air outlet at the top of the cooling box 1 and input into the waste gas treatment system. Compared with the existing technology, the cooling box 1 will not shake, has good structural stability, and can carry out continuous feeding and discharging cooling process. It avoids the problems of long cooling time and poor cooling uniformity after a large amount of pesticide suspension is loaded into the cooling box, and has good practicality.

[0025] The guide cone 9 blocks the cold air output from the air supply cap 8 and directs it to the edge, preventing cold air from rushing into the feed pipe 18 and interfering with the feeding of pesticide suspension powder, thus improving feeding reliability. By setting the spiral blades 5 with an outwardly inclined vertical section, the pesticide suspension powder on the spiral blades 5 is concentrated on the inner wall of the cooling box 1, preventing the pesticide suspension powder from falling into the fluidized bed hopper 4, and increasing the contact area between the pesticide suspension powder and the cooling box 1, thereby improving the cooling effect.

[0026] Example 2

[0027] like Figure 1 , Figure 2 and Figure 7As shown, based on Embodiment 1, it also includes a filter plate 10, which is installed on the upper outer wall of the feeding pipe 18. The outer wall of the feeding pipe 18 slides in contact with the inner wall of the cylinder 6. It also includes a brush plate 12 and brush bristles 13. The brush plate 12 is installed on the inner wall of the cylinder 6 and is located above the filter plate 10. A large number of brush bristles 13 are installed on the brush plate 12, and the lower ends of the brush bristles 13 make brushing contact with the filter plate 10. The filter plate 10 is used to intercept pesticide suspension powder that rises with the cold air, so as to avoid the spread of pesticide suspension powder and cause pollution and toxicity. When the cylinder 6 rotates, it drives the brush plate 12 to rotate, so that the brush plate 12 drives the brush bristles 13 to brush the filter holes of the filter plate 10 and clear the blocked filter holes.

[0028] Example 3

[0029] like Figure 1 , Figure 2 and Figure 7 As shown, based on Embodiment 1, it includes a filter plate 10, which is mounted on the upper outer wall of a feeding pipe 18. The outer wall of the feeding pipe 18 slides in contact with the inner wall of the cylinder 6. It also includes a brush roller 14, brush bristles 15, a bevel gear 16, and a bevel gear ring 17. The brush roller 14 is rotatably mounted on the inner wall of the cylinder 6. Multiple brush bristles 15 are circumferentially mounted on the outer wall of the brush roller 14. The lower ends of the brush bristles 15 brush into contact with the filter plate 10. The bevel gear 16 is concentrically mounted on the inner end of the brush roller 14. The bevel gear 16 meshes with the bevel gear ring 17, which is concentrically mounted on the outer wall of the feed pipe 18. The filter plate 10 is used to intercept pesticide suspension powder that rises with the cold air, preventing the pesticide suspension powder from spreading and causing pollution and toxicity. When the cylinder 6 rotates, it drives the brush roller 14 to rotate around the feed pipe 18. The bevel gear 16 meshes with the bevel gear ring 17, thereby driving the brush roller 14 to rotate, so that the brush roller 14 drives the bristles 15 to brush the filter holes of the filter plate 10 and clear the blocked filter holes.

[0030] like Figures 1 to 7As shown, this utility model discloses a pesticide suspension cooling device. During operation, the cooling water jacket 2 is connected to an external cooling water system, allowing the cooling water jacket 2 to cool the cooling tank 1. The drive mechanism 7 drives the cylinder 6 to rotate, which in turn drives the spiral blades 5 to rotate. Then, pesticide suspension powder is added to the center bottom of the fluidized bed hopper 4 through the feeding pipe 18. The cold air fan 3 evenly delivers cold air to the bottom of the fluidized bed hopper 4 through the air supply cap 8. The cold air blows the pesticide suspension powder upwards, creating a fluidized bed state, allowing the pesticide suspension powder to fully contact the cold air for air cooling. Then, as the pesticide suspension powder is conveyed through the feeding pipe 18, it overflows from the fluidized bed hopper 4. The pesticide suspension powder enters the spiral blades 5 between the inner wall of the fluidized bed hopper 4 and the cooling box 1. The rotating spiral blades 5 lift the pesticide suspension powder upwards. During the lifting process, the pesticide suspension powder comes into contact with the low-temperature outer wall of the cooling box 1 for cooling. After reaching the top of the cooling box 1, the cooled pesticide suspension powder is discharged through the outlet. Finally, during this process, the pesticide suspension powder blown up by the cold air falls onto the spiral blades 5 through the gap between the fluidized bed hopper 4 and the cylinder 6. The cold air discharged from the fluidized bed hopper 4 is intercepted by the rising pesticide suspension powder when it passes through the filter plate 10. The cold air passing through the filter plate 10 is discharged from the cooling box 1 through the air outlet at the top of the cooling box 1 and input into the exhaust gas treatment system.
