Description

Technical Field

[0001] This application relates to the field of grinding mills, and more specifically, to a high-efficiency air-cooled cooling device for grinding mills. Background Technology

[0002] As the core equipment for powder processing, grinding mills play a crucial role in many basic industrial fields such as metallurgy, building materials, chemicals, and mining. Their technical level and product quality are directly related to the production efficiency and product quality of downstream industries. The existing cooling device for grinding mills works by cooling the indoor and outdoor air through a cold air fan, and then sending the cooled air into the grinding mill. With the help of the fan's driving force, the cold air cools down the materials and key components such as grinding blades in the grinding mill.

[0003] Currently, grinding mill cooling devices rely solely on air coolers to cool the materials and components within the grinding chamber. In hot summer environments or workshops, the initial temperature of the external air drawn in by the air coolers is already high. After simple processing, it is difficult to achieve the desired cooling effect, which can easily lead to heat accumulation in the grinding chamber. This can not only cause the materials to deteriorate and change in performance due to high temperatures, but also accelerate the wear and aging of the grinding components. At the same time, this cooling method has limited heat dissipation efficiency. When grinding high-viscosity materials or operating continuously for extended periods, which generates a lot of heat, relying solely on airflow to remove heat cannot effectively dissipate a large amount of frictional heat, which can easily lead to excessively high discharge temperatures and affect the stability of product quality. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] The purpose of this application is to address the shortcomings of existing technologies by providing a high-efficiency air-cooled cooling device for grinding mills. This addresses the problem that existing technologies rely solely on air coolers to cool materials and components within the grinding chamber. In hot summer environments or workshops, the initial temperature of the external air drawn in by the air cooler is already high, and even with simple processing, it is difficult to achieve the desired cooling effect. This easily leads to heat accumulation within the grinding chamber, which may cause material deterioration and performance changes due to high temperatures, and also accelerates the wear and aging of grinding components. Furthermore, this cooling method has limited heat dissipation efficiency. In scenarios involving high-viscosity material grinding or long-term continuous operation with high heat generation, relying solely on airflow to remove heat cannot effectively dissipate a large amount of frictional heat, leading to excessively high discharge temperatures and affecting the stability of product quality.

[0006] To achieve the above objectives, this application provides the following technical solution: A high-efficiency air-cooled cooling device for a grinding mill includes: a base frame; a grinding box is fixedly mounted on one side of the upper part of the base frame; a feed inlet is provided in the upper middle part of the grinding box, and a solenoid valve is installed on one section of the feed inlet; a grinding mechanism is jointly arranged inside and outside the grinding box; a high-efficiency cooling mechanism is jointly arranged on both sides of the grinding box and one side of the base frame; the high-efficiency cooling mechanism includes a connecting seat, which is fixedly mounted on one side of the bottom end of the base frame; a water storage tank is mounted on top of the connecting seat; cooling components are jointly arranged on both sides of the grinding box and one side of the connecting seat; and a water exchange component is provided outside the water storage tank.

[0007] Furthermore, the cooling assembly includes a side-mounted bracket, which is fixed to one side of the grinding chamber. A cooling fan is installed on the outer side of the side-mounted bracket. A first connecting water pipe is jointly installed on the lower section of one side of the water tank and the middle section of the side-mounted bracket. A circulating water pump is installed in the middle section of one section of the first connecting water pipe. An air inlet filter is provided on the inner side of the side-mounted bracket. An air outlet filter is provided on the other side of the grinding chamber. A side-mounted heat dissipation guide is fixed above one side of the connecting seat. A heat dissipation fan is installed in the middle of the outer side of the side-mounted heat dissipation guide. A second connecting water pipe is installed on the inner side of the side-mounted heat dissipation guide. Heat dissipation fins are distributed around multiple sections of the second connecting water pipe. Support brackets are provided at multiple sections of the second connecting water pipe and the first connecting water pipe.

[0008] Furthermore, the first connecting water pipe and the second connecting water pipe are arranged in a staggered manner, and the first connecting water pipe is connected to the second connecting water pipe.

[0009] Furthermore, the heat dissipation fins are evenly arranged around the adjacent sections of the second connecting water pipe in a staggered pattern.

[0010] Furthermore, the water exchange assembly includes a drain pipe, which is located on the lower side of the water storage tank. A drain valve is provided on one end of the drain pipe. A threaded sleeve is provided above the water storage tank, and a threaded plug is installed on the periphery of the threaded sleeve.

[0011] Furthermore, the grinding mechanism includes a drive motor, which is mounted on one side above the base frame. A first synchronous pulley is fixed around the output end of the drive motor, and a synchronous belt is sleeved around the periphery of the first synchronous pulley. A second synchronous pulley is provided on the inner side of the other side of the synchronous belt, and a first rotating rod is fixed in the middle of the second synchronous pulley. A second rotating rod is provided on one side of the first rotating rod, and grinding rollers are installed around the periphery of the second rotating rod and the first rotating rod. Gears are fixed around the same section of the second rotating rod and the first rotating rod.

[0012] Furthermore, the second rotating rod and the first rotating rod are coupled and aligned by gears fixed to the periphery of the same section, which drive the grinding rollers mounted on their respective peripheries in a meshing manner.

[0013] The beneficial effects of this application are as follows: During the grinding process, the circulating water pump, cooler, and cooling fan can be started simultaneously. At this time, the cold water in the storage tank, guided by the pump, flows sequentially through the staggered first and second connecting water pipes, eventually returning to the storage tank to repeat the previous cycle. When the cold water flows through the first connecting water pipe arranged within the side frame, the cooler blows ambient airflow drawn in from the outside onto the first connecting water pipe carrying the cold water. The cold water cools the pipe walls, and the flowing airflow is cooled by the pipe walls, forming cold air. This cold air is sent into the grinding chamber to absorb heat from the grinding materials and components, and then discharged from the convection outlet filter. This achieves the purpose of cooling. Subsequently, the cold water in the first connecting water pipe, which has been heated by absorbing heat from the external airflow, will flow into the second connecting water pipe, which is laid out in a row. At this time, the cooling fan will continue to run to cool down the heated water in the second connecting water pipe. Since the adjacent sections of the second connecting water pipe are equipped with heat dissipation fins, the heat dissipation rate can be further improved, so that the cooled water after heat exchange can flow back into the water tank for recycling. It is worth mentioning that the staff needs to regularly drain and replace the cold water in the water tank through the coordinated action of the various components of the water exchange assembly to reduce the accumulation of scale and impurities.

[0014] The staff first opens the solenoid valve, then introduces the material to be ground into the grinding box through the feed inlet. Next, the drive motor is started. At this time, under the transmission action of the first synchronous pulley, the synchronous belt and the second synchronous pulley, the first rotating rod on one side of the middle of the grinding box rotates accordingly. Since the second rotating rod is provided on the other side of the grinding box, and gears are fixed around the same end of the two rotating rods, the two rotating rods will drive the grinding rollers installed around their respective middle parts to move relative to each other through gear meshing, thereby realizing the grinding of the material.

The second rotating rod 56 and the first rotating rod 55 are driven by the gears 58 fixed around the same section to mesh with the grinding rollers 57 installed around their respective peripheries in a meshing manner. The operator first opens the solenoid valve 4, and then introduces the material to be ground into the grinding box 2 from the feed inlet 3. Then, the drive motor 51 is started. At this time, under the transmission action of the first synchronous pulley 52, the synchronous belt 53 and the second synchronous pulley 54, the first rotating rod 55 on one side of the middle of the grinding box 2 rotates accordingly. Since the second rotating rod 56 is provided on the other side of the inside of the grinding box 2, and gears 58 are fixed around the same end of both rotating rods, the two rotating rods will drive the grinding rollers 57 installed around their respective middle peripheries to move relative to each other through the meshing of the gears 58, thereby realizing the grinding of the material.

[0024] The high-efficiency cooling mechanism 6 includes a connecting seat 61, which is fixed to one side of the bottom of the base frame 1. A water storage tank 62 is mounted on top of the connecting seat 61. Cooling components 63 are jointly arranged on both sides of the grinding chamber 2 and on one side of the connecting seat 61. The cooling components 63 include a side mounting bracket 631, which is fixed to one side of the grinding chamber 2. A cooler 632 is mounted on the outer side of the side mounting bracket 631. A first connecting water pipe 633 is jointly installed on the lower section of one side of the water storage tank 62 and the middle section of the side mounting bracket 631. A circulating water pump 634 is installed in the middle of one section of the first connecting water pipe 633. An air inlet filter 636 is provided on the inner side of the side mounting bracket 631, and an air outlet filter 635 is provided on the other side of the grinding chamber 2. A side-mounted heat dissipation guide 637 is fixedly installed on the upper side, and a heat dissipation fan 638 is installed on the middle of the outer side of the side-mounted heat dissipation guide 637. A second connecting water pipe 639 is installed on the inner side of the side-mounted heat dissipation guide 637. The first connecting water pipe 633 and the second connecting water pipe 639 are arranged in a staggered manner, and the first connecting water pipe 633 is connected to the second connecting water pipe 639. Heat dissipation fins 6310 are provided around multiple sections of the second connecting water pipe 639. Support brackets 6311 are provided at multiple sections of the second connecting water pipe 639 and the first connecting water pipe 633. The heat dissipation fins 6310 are evenly arranged around adjacent sections of the staggered second connecting water pipe 639. A water exchange assembly 64 is provided on the outside of the water tank 62. Component 64 includes a drain pipe 641, which is located on the lower side of the water storage tank 62.

A threaded sleeve block 643 is installed above the water storage tank 62, and a threaded plug 644 is installed on the periphery of the threaded sleeve block 643. During the grinding process, the circulating water pump 634, the air cooler 632, and the cooling fan 638 can be started simultaneously. At this time, the cold water in the water storage tank 62 will be guided by the pump force to pass through the staggered first connecting water pipe 633 and the second connecting water pipe 639 in sequence, and finally flow back to the water storage tank 62 to repeat the previous cycle. When the cold water flows through the first connecting water pipe 633 arranged in the side mounting frame 631, the air cooler 632 will draw in the ambient temperature airflow from the outside. The airflow is blown towards the first connecting water pipe 633, which carries cold water. After the cold water cools the pipe wall, the airflow is cooled by the pipe wall and forms cold air. This cold air is sent into the grinding box 2 to absorb the heat of the grinding material and components, and then discharged from the convection outlet filter 635, thereby achieving the purpose of cooling. Subsequently, the cold water in the first connecting water pipe 633, which has been heated by absorbing the heat of the external airflow, will flow into the second connecting water pipe 639. At this time, the cooling fan 638 will continue to run to cool the heated water source in the second connecting water pipe 639. Since the second connecting water pipe 639 is equipped with heat dissipation fins 6310 on the periphery of the adjacent section, the heat dissipation rate can be further improved, so that the cooled water after heat exchange can flow back to the water storage tank 62 for recycling.It is worth mentioning that staff need to periodically drain and replace the cold water in the water tank 62 through the coordinated action of the various components of the water exchange assembly 64, in order to reduce the accumulation of scale and impurities.

[0025] Working Principle: This grinding mill uses a high-efficiency air-cooled cooling device. During operation, the operator first opens the solenoid valve 4, then introduces the material to be ground into the grinding chamber 2 through the feed inlet 3. Next, the drive motor 51 is started. Under the transmission action of the first synchronous pulley 52, the synchronous belt 53, and the second synchronous pulley 54, the first rotating rod 55 on one side of the middle of the grinding chamber 2 rotates accordingly. Since a second rotating rod 56 is located on the other side inside the grinding chamber 2, and gears 58 are fixed around the same end of both rotating rods, the two... Each rotating rod, through gear 58, drives the grinding rollers 57 mounted around their respective central peripheries to move relative to each other, thereby achieving the grinding of materials. During the grinding process, the circulating water pump 634, the cool air fan 632, and the cooling fan 638 can be started simultaneously. At this time, the cold water in the water tank 62, guided by the pump force, flows sequentially through the staggered first connecting water pipe 633 and the second connecting water pipe 639, and finally flows back to the water tank 62 to repeat the previous cycle. When the cold water flows through the side mounting frame 631, the grinding rollers 57 are arranged in a staggered manner. When the first connecting water pipe 633 is installed, the air cooler 632 blows the ambient airflow drawn in from the outside onto the first connecting water pipe 633, which carries cold water. After the cold water cools the pipe wall, the airflow is cooled by the pipe wall, forming cold air. This cold air is sent into the grinding chamber 2 to absorb the heat from the grinding materials and components, and then discharged from the convection outlet filter 635, thereby achieving the purpose of cooling. Subsequently, the cold water in the first connecting water pipe 633, which has been heated by absorbing the heat from the external airflow, will flow into the second connecting water pipe 639, which is laid out in a row. At this time, the cooling fan 638 will continue to run to cool the heated water source in the second connecting water pipe 639. Since the second connecting water pipe 639 is equipped with heat dissipation fins 6310 on the periphery of the adjacent section, the heat dissipation rate can be further improved, so that the cooled water after heat exchange can flow back into the water storage tank 62 for recycling. It is worth mentioning that the staff needs to regularly drain and replace the cooled water in the water storage tank 62 through the coordinated action of the various components of the water exchange component 64 to reduce the accumulation of scale and impurities.
