Description

Technical Field

[0001] The present invention relates to the technical field of stirring equipment, and particularly relates to a temperature-controlled stirring equipment for insect control agents. Background Art

[0002] Insect control agents, namely insecticides, refer to agents that poison harmful insects through ways such as contact poisoning and stomach poisoning, such as beetles, flies, grubs, weevils, springtails, and nearly ten thousand other pests. The use of insecticides has gone through several stages: the earliest discovered were natural insecticides and inorganic compounds, but they have a single function, large dosage, and short effective period; followed by organic synthetic insecticides such as organochlorines, organophosphates, and carbamates, which are characterized by high efficiency and high residues or low residues, and many of them have high acute toxicity to mammals. It is mainly used to control agricultural pests and urban sanitation pests, with a long history of use, large dosage, and many varieties. In the 20th century, insecticides were widely used in the control of agricultural pests, which promoted a significant increase in crop yields. However, the unscientific use of insecticides has led to a reduction in insecticidal efficiency. A large amount of insecticides penetrate into groundwater and accumulate in the food chain, causing serious environmental pollution and endangering the ecosystem. Therefore, to achieve a balance between agricultural development and the environment and health, insecticides must be used scientifically and reasonably to improve the poisoning efficiency of insecticides.

[0003] During the production of insecticide emulsions, they are formulated by mixing various agents, and emulsifying agents also need to be added internally. The emulsifying performance of the emulsifying agent can evenly disperse the small oil droplets of the insecticide dissolved in the oil in water to form a stable emulsion. However, during the mixing and stirring process, a large amount of foam and floating substances formed by the emulsifying agent will be generated on the surface of the insecticide suspension. In order not to affect the production and processing of the drug and improve the insecticidal efficiency, it is necessary to remove these foam and floating substances formed by the emulsifying agent. The traditional treatment methods are all carried out by manual fishing, which is time-consuming and laborious and affects the physical health of the staff. Summary of the Invention

[0004] The embodiment of the present invention provides a temperature-controlled stirring equipment for insect control agents. During the mixing and stirring process, the temperature of the kettle body is controlled by a temperature control system to reduce the stability of the foam and reduce the generation of foam.

[0023] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the technical solutions of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0024] As Figures 1 to 6 shown, a temperature-controllable stirring device for insect control agents includes a kettle body 1 and a temperature control system. The upper end of the kettle body 1 is provided with a feed port with a sealing cover, the lower end of the kettle body 1 is provided with a discharge pipe with a discharge valve, a stirrer is rotatably connected inside the kettle body 1, a motor 8 for driving the stirrer to rotate is provided at the upper end of the kettle body 1, a water pump is provided outside the kettle body 1, a floating plate 2 that can float on the surface of the suspension is provided inside the kettle body 1, a plurality of straws 3 communicated with the water pump are evenly arranged on the floating plate 2, and a plurality of liquid suction holes 4 are opened on the side surface of the straw 3;

[0025] The temperature control system includes a jacket 5 provided outside the kettle body 1. A medium cavity 6 for storing heat-conducting medium is formed between the jacket 5 and the outer wall of the kettle body 1. The temperature control system further includes a high-temperature heat exchanger and a low-temperature heat exchanger that perform heat exchange with the heat-conducting medium in the medium cavity 6. The temperature control system further includes a controller and a temperature sensor 7 provided inside the kettle body 1 and electrically connected to the controller.

[0026] During specific use, set the temperature range inside the kettle body 1 through the controller. Add the raw materials into the kettle body 1 through the feed port. When the motor 8 drives the stirrer during stirring, the temperature sensor 7 monitors the temperature inside the kettle body 1 in real time and transmits the temperature information to the controller. The controller controls the high-temperature heat exchanger or the low-temperature heat exchanger to adjust the temperature of the heat-conducting medium in the jacket 5 based on the temperature information inside the kettle body 1, so as to keep the temperature inside the kettle body 1 stable within the set range. Appropriately increase the temperature inside the kettle body 1. By raising the temperature, reduce the stability of the foam and reduce the generation of foam. At the same time, avoid the temperature being higher than 40 degrees to prevent the emulsification performance of the emulsifiable concentrate from being reduced due to excessive temperature. The water pump works to suck out the floating objects formed by a small amount of foam and emulsifiable concentrate generated during stirring through the suction pipe 3 on the floating plate 2 floating on the surface of the suspension. After stirring is completed, open the discharge valve, and the insect control agent is discharged from the discharge pipe.

[0027] To achieve the purpose of automatically removing the floating objects formed by a small amount of foam and emulsifiable concentrate on the suspension, preferably, the stirrer includes a rotating shaft 9 and a plurality of stirring blades 10 arranged on the rotating shaft 9.

[0028] The output end of the motor 8 is provided with a driving bevel gear 15. The rotating shaft 9 includes an outer shaft sleeve 901, an inner shaft sleeve 902, and a stirring rod 903. The outer shaft sleeve 901 is rotatably connected to the upper end of the kettle body 1. The inner surface of the outer shaft sleeve 901 is provided with a first limiting groove 11. The outer surface of the inner shaft sleeve 902 is provided with a first limiting plate 12 that is slidably connected to the first limiting groove 11. The inner surface of the inner shaft sleeve 902 is provided with a second limiting groove 13. The surface of the stirring rod 903 is provided with a second limiting plate 14 that is slidably connected to the second limiting groove 13. The lower end of the stirring rod 903 is rotatably connected to the inner bottom wall of the kettle body 1. The stirring blades 10 are evenly arranged on the stirring rod 903. The outer shaft sleeve 901 is provided with a first driven bevel gear 16 that meshes with the driving bevel gear 15. The floating plate 2 is arranged on the inner shaft sleeve 902.

[0029] The water pump includes a piston cylinder 17 fixedly connected to the kettle body 1. A liquid guide pipe 18 and a liquid discharge pipe 19 are arranged at the upper end of the piston cylinder 17. A piston 20 is slidably connected inside the piston cylinder 17. A piston rod 21 that is slidably connected to the bottom wall of the piston cylinder 17 is arranged at the lower end of the piston 20. The water pump also includes a second driven bevel gear 34 arranged on the kettle body 1 that meshes with the first driven bevel gear 16. A turntable 22 is coaxially arranged on the second driven bevel gear 34. An eccentric column 23 is eccentrically arranged on the turntable 22. A connecting rod 24 that is hinged to the piston rod 21 is rotatably connected to the eccentric column 23.

[0030] The upper end of the inner shaft sleeve 902 is rotatably connected to a rotary joint 25 that is communicated with the liquid guide pipe 18. A diversion channel 26 that is communicated with the suction pipe 3 is opened inside the inner shaft sleeve 902 and the floating plate 2.

[0031] The motor 8 operates to drive the first driven bevel gear 16 to rotate through the driving bevel gear 15. The first driven bevel gear 16 drives the outer shaft sleeve 901 and the second driven bevel gear 34 to rotate. The outer shaft sleeve 901 drives the inner shaft sleeve 902 to rotate through the first limiting groove 11. The inner shaft sleeve 902 drives the stirring rod 903 to rotate through the second limiting groove 13. The stirring rod 903 drives the stirring blades 10 to rotate to stir and emulsify the suspension. The second driven bevel gear 34 drives the eccentric column 23 on the turntable 22 to rotate. The eccentric column 23 drives the piston rod 21 and the piston 20 to perform a reciprocating linear motion inside the piston cylinder 17 to form a negative pressure at the liquid suction hole 4, so that a small amount of foam floating on the surface of the suspension and the floating matter formed by the emulsifiable concentrate enter the suction pipe 3 from the liquid suction hole 4, and enter the piston cylinder 17 through the diversion channel 26, and finally are discharged from the liquid outlet pipe 19. The advantages are that the inner shaft sleeve 902 drives the suction pipe 3 on the floating plate 2 to rotate continuously, increasing the cleaning area of the foam and the floating matter, and the cleaning effect is better. Moreover, the floating plate 2 can drive the suction pipe 3 to rise and fall with the liquid level of the suspension, and is not affected by the liquid level height.

[0032] In order to achieve the purpose of improving the cleaning effect on the floating matter formed by the foam and the emulsifiable concentrate, preferably, check valves are respectively arranged inside the liquid guide pipe 18 and the liquid outlet pipe 19. The check valve on the liquid guide pipe 18 only allows the floating matter formed by the foam and the emulsifiable concentrate to flow from the liquid guide pipe 18 to the piston cylinder 17, and the check valve on the liquid outlet pipe 19 only allows the floating matter formed by the foam and the emulsifiable concentrate to flow from the piston cylinder 17 to the liquid outlet pipe 19, preventing backflow.

[0033] In order to achieve the purpose of controlling the temperature inside the kettle body 1, preferably, the high-temperature heat exchanger includes a high-temperature heat exchange box 27 for storing the heat transfer medium. A first heat exchange coil 28 is arranged inside the high-temperature heat exchange box 27. Both ends of the first heat exchange coil 28 pass through the high-temperature heat exchange box 27. One end is connected to a steam generator 32, and the other end is a condensate outlet.

[0034] The low-temperature heat exchanger includes a low-temperature heat exchange box 29 for storing the heat transfer medium. A second heat exchange coil 30 is arranged inside the low-temperature heat exchange box 29. Both ends of the second heat exchange coil 30 pass through the low-temperature heat exchange box 29. One end is connected to a water pump 31 connected to external chilled water, and the other end is a chilled water outlet.

[0035] A third heat exchange coil 33 passing through the high-temperature heat exchange box 27 and the low-temperature heat exchange box 29 is arranged between the upper end and the lower end of the jacket 5. A circulation pump is arranged on the third heat exchange coil 33.

[0036] When the temperature inside the kettle body 1 is higher than the set value, the steam generator 32 is turned off, and the water pump 31 operates to extract external chilled water. The chilled water flows in the second heat exchange coil 30 and exchanges heat with the heat conduction medium in the low-temperature heat exchange tank 29, reducing the temperature of the heat conduction medium in the low-temperature heat exchange tank 29. The circulation pump starts to drive the heat conduction medium in the jacket 5 to circulate in the third heat exchange coil 33. The heat conduction medium in the low-temperature heat exchange tank 29 then exchanges heat with the heat conduction medium in the jacket 5 through the third heat exchange coil 33, reducing the temperature of the heat conduction medium in the jacket 5, and further reducing the temperature inside the kettle body 1. When the temperature inside the kettle body 1 is lower than the set value, the water pump 31 is turned off, and the steam generator 32 operates to generate water steam. The water steam enters the first heat exchange coil 28 and exchanges heat with the heat conduction medium in the high-temperature heat exchange tank 27, increasing the temperature of the heat conduction medium in the high-temperature heat exchange tank 27. The circulation pump starts to drive the heat conduction medium in the jacket 5 to circulate in the third heat exchange coil 33. The heat conduction medium in the high-temperature heat exchange tank 27 then exchanges heat with the heat conduction medium in the jacket 5 through the third heat exchange coil 33, increasing the temperature of the heat conduction medium in the jacket 5, and further increasing the temperature inside the kettle body 1, realizing the automatic control of the temperature.

[0037] Compared with the prior art, the present invention is provided with the cooperation of the kettle body 1, the temperature control system, the feed inlet, the discharge pipe, the stirrer, the motor 8, the water pump, the floating plate 2, the suction pipe 3, the liquid suction holes 4, the jacket 5, the medium cavity 6, the high-temperature heat exchanger, the low-temperature heat exchanger, the controller and the temperature sensor 7. By setting the temperature range inside the kettle body 1 through the controller, during the stirring process driven by the motor 8, the temperature sensor 7 monitors the temperature inside the kettle body 1 in real time and transmits the temperature information to the controller. The controller controls the high-temperature heat exchanger or the low-temperature heat exchanger to adjust the temperature of the heat conduction medium in the jacket 5 according to the temperature information inside the kettle body 1, so as to stably maintain the temperature inside the kettle body 1 within the set range. Appropriately increasing the temperature inside the kettle body 1 can reduce the stability of the foam and the generation of foam by heating, and at the same time avoid the temperature being higher than 40 degrees, preventing the emulsifying performance of the emulsifiable concentrate from being reduced due to excessive temperature. The water pump operates to suck out the floating substances formed by a small amount of foam and emulsifiable concentrate generated during the stirring process through the suction pipe 3 on the floating plate 2 floating on the surface of the suspension liquid, eliminating the need for manual fishing, saving time and effort, and being beneficial to the physical health of the staff.
