Description

Technical Field

[0001] This utility model relates to the field of chemical dosing equipment, and more specifically, to a chemical dosing device for a cooling tower. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from the system and release it into the atmosphere to lower the water temperature. Air cooling is an evaporative cooling device that uses the contact between water and air flow to exchange heat and generate steam. The steam evaporates and carries away heat, achieving heat dissipation through evaporation, convection, and radiation. This process dissipates waste heat generated in industrial processes or refrigeration and air conditioning systems to lower the water temperature and ensure the normal operation of the system. The device is generally cylindrical.

[0003] For example, a cooling tower circulating water automatic dosing device disclosed in Chinese invention patent / utility model patent (application number: CN218962339U) includes: a base, a box fixedly connected to the upper end of the base, a second rotating rod provided inside the box, a protective shell provided outside the second rotating rod, a first rotating rod provided on both sides of the protective shell, a first bevel gear fixedly connected to the outside of the second rotating rod, a third rotating rod fixedly connected to the lower end of the first bevel gear, the lower end of the third rotating rod extending through one side of the protective shell to the outside, and a second stirring rod fixedly connected to the outside;

[0004] Although the aforementioned patent can mix the agent with water, the device still has the following problems: During the use of the device, due to the long-term use, the particles in the agent will adhere to the inner wall of the device, so it is necessary to clean it regularly to prevent cross-contamination of different batches of agents or bacterial growth. However, since the device is not equipped with a cleaning device, cleaning the device is quite cumbersome.

[0005] Therefore, we have made improvements to this and proposed a chemical dosing device for cooling towers. Utility Model Content

[0006] The purpose of this invention is to solve the problem of the current device being too cumbersome to clean.

[0007] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a chemical dosing device for a cooling tower, comprising a device body, a motor fixedly connected to the top of the device body, a rotating shaft fixedly connected to the output end of the motor, a stirring frame fixedly connected to the surface of the rotating shaft, the stirring frame having an X-shaped cross-section, a support frame rotatably connected to the bottom of the stirring frame, scrapers fixedly connected to both sides of the support frame, a collection frame fixedly connected to the outer surface of the rotating shaft, a mesh opening on the bottom plate of the collection frame, and a water spray cleaning device provided on the device body.

[0008] As a preferred technical solution of this application, the water spray cleaning device includes a water collecting ring, the top of which is fixedly connected to the upper surface inside the device body, and a rotating ring extending to the outside of the water collecting ring is rotatably connected inside the water collecting ring. A spray head is provided at the bottom of the rotating ring, and a scraper is fixedly connected to the surface of the rotating ring on the side near the rotating ring.

[0009] As a preferred technical solution of this application, a water tank is fixedly connected to the top of the device body, and a pump body is fixedly connected to the top of the device body. The water inlet end of the pump body is connected to the inside of the water tank through a pipe, and a water supply pipe is fixedly connected to the drain end of the pump body. The end of the water supply pipe away from the pump body is fixedly connected to the inside of the water collection ring.

[0010] As a preferred technical solution of this application, a stirring rod is fixedly connected to one side of the scraper.

[0011] As a preferred technical solution of this application, a support box is fixedly connected to the upper surface inside the device body, and the surface of the rotating shaft is rotatably connected to the inside of the support box.

[0012] As a preferred technical solution of this application, a disturbance rod is fixedly connected to the bottom of the support box.

[0013] As a preferred technical solution of this application, a first gear is fixedly connected to the surface of the rotating shaft, and a second gear is rotatably connected to the inside of the support box.

[0014] As a preferred technical solution of this application, the surface of the second gear meshes with the surface of the first gear, and the inner surface of the rotating ring is provided with teeth, and the rotating ring meshes with the surface of the second gear through the teeth.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] 1. By setting up a water collection ring, a rotating ring, and a scraper, the nozzle can spray water flowing into the rotating ring from inside the water collection ring, making the cleaning of the inner wall of the equipment body smoother and allowing workers to clean the inner wall of the equipment body more conveniently. At the same time, through the cooperation of the rotating ring and the scraper, the cleaning of the inner wall of the equipment body is more thorough and the device is easier for workers to use.

[0018] 2. By setting up a first gear, a second gear, and a rotating ring, the first gear drives the rotating ring to rotate through the second gear, and the rotating ring and the rotating shaft rotate in opposite directions. This also causes the scraper to rotate in the opposite direction to the rotating shaft, thus improving the mixing quality of the pharmaceutical solution. Furthermore, the X-shaped stirring frame allows the device to perform multi-directional stirring of the pharmaceutical solution, resulting in more uniform mixing. This also makes the device easier for operators to use. The equipment itself can be equipped with external water pumps and pressure pumps to add chemicals to the cooling tower.

A stirring frame 11 is fixedly connected to the surface of the rotating shaft 10. The stirring frame 11 has an X-shaped cross section. A support frame 12 is rotatably connected to the bottom of the stirring frame 11. Scrapers 13 are fixedly connected to both sides of the support frame 12. The scrapers 13 can scrape and clean the inner wall of the device body 1. A feed pipe is provided at the top of the device body 1. A collection frame 14 is fixedly connected to the outer surface of the rotating shaft 10. A mesh hole is opened on the bottom plate of the collection frame 14. The material enters the interior of the collection frame 14, and the collection frame 14 can sprinkle the material when rotating, making the material more uniformly mixed. A water spray cleaning device is provided on the device body 1.

[0031] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the water spray cleaning device includes a water collecting ring 6, the top of which is fixedly connected to the upper surface inside the device body 1. The water collecting ring 6 can store water flow. A rotating ring 7 extending to the outside of the water collecting ring 6 is rotatably connected inside the water collecting ring 6. A nozzle 8 is provided at the bottom of the rotating ring 7. The nozzle 8 can spray the water flow entering the rotating ring 7 from the inside of the water collecting ring 6, making the cleaning of the inner wall of the device body 1 smoother and allowing the staff to clean the inner wall of the device body 1 more conveniently. The scraper 13 is fixedly connected to the surface of the rotating ring 7 on the side near the rotating ring 7. The rotating ring 7 can drive the scraper 13 to rotate.

[0032] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a water tank 2 is fixedly connected to the top of the device body 1. The water tank 2 can hold water. A pump body 4 is fixedly connected to the top of the device body 1. The pump body 4 is an existing structure and will not be described in detail here. The water inlet of the pump body 4 is connected to the inside of the water tank 2 through a pipe. The water outlet of the pump body 4 is fixedly connected to a water supply pipe 5. The end of the water supply pipe 5 away from the pump body 4 is fixedly connected to the inside of the water collection ring 6. The pump body 4 can draw water from the inside of the water tank 2 and make the water flow into the inside of the water collection ring 6 for cleaning.

[0033] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a stirring rod 18 is fixedly connected to one side of the scraper 13. The stirring rod 18 and the stirring frame 11 can stir the medicine liquid inside the equipment body 1. The stirring frame 11 is X-shaped, which enables the device to stir the medicine liquid in multiple directions and make the mixture of the medicine liquid more uniform. At the same time, it makes it easier for the staff to use the device.

[0034] Example 2

[0035] The chemical dosing equipment for the cooling tower provided in Example 1 is further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a support box 9 is fixedly connected to the upper surface inside the equipment body 1. The surface of the rotating shaft 10 is rotatably connected to the inside of the support box 9. A first gear 15 is fixedly connected to the surface of the rotating shaft 10. A second gear 16 is rotatably connected to the inside of the support box 9. A disturbance rod 17 is fixedly connected to the bottom of the support box 9. The material inside the collection frame 14 can be disturbed by the disturbance rod 17.

[0036] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the surface of the second gear 16 meshes with the surface of the first gear 15. The inner surface of the rotating ring 7 is provided with teeth. The rotating ring 7 meshes with the surface of the second gear 16 through the teeth. The rotating shaft 10 drives the first gear 15 to rotate. The first gear 15 causes the rotating ring 7 to rotate through the second gear 16, and the rotating ring 7 and the rotating shaft 10 rotate in opposite directions, thus making the cleaning inside the device more convenient.

[0037] The operation of the chemical dosing equipment for the cooling tower provided by this utility model is as follows: The operator feeds the material into the equipment body 1 through the feed pipe. After the material enters the collection frame 14, the operator starts the motor 3, which drives the collection frame 14 to rotate, allowing the collection frame 14 to scatter the material inside. Simultaneously, the agitator 17 agitates the material inside the collection frame 14, making it fall more smoothly into the equipment body 1 for mixing. At the same time, the rotating shaft 10 drives the stirring frame 11 to rotate, allowing the stirring frame 11 to mix the chemical solution. The rotating shaft 10 drives the first gear 15 to rotate, and the first gear 15 drives the rotating ring 7 to rotate through the second gear 16. The rotating ring 7 and the rotating shaft 10 rotate in opposite directions, and the scraper 13 rotates in the opposite direction to the rotating shaft 10. This improves the mixing quality of the medicine. The X-shaped stirring frame 11 allows the device to stir the medicine in multiple directions and make the mixing more uniform. It also makes it easier for the staff to use the device. The main body of the equipment 1 can add medicine to the cooling tower through an external water pump and a pressure pump.

[0038] When the device needs cleaning, the operator starts the pump body 4, which draws water from the water tank 2 and directs it into the water collection ring 6 for cleaning. The nozzle 8 sprays the water from the water collection ring 6 into the rotating ring 7, making the cleaning of the inner wall of the device body 1 smoother and easier for the operator to clean. At the same time, the cooperation between the rotating ring 7 and the scraper 13 makes the cleaning of the inner wall of the device body 1 more thorough and makes the device easier for the operator to use.
