Description

Technical Field

[0001] This utility model relates to the field of chiller technology, and more specifically to a small-sized bottom-mounted chiller. Background Technology

[0002] Crushers typically break materials into smaller particles. Most existing crusher models do not have dedicated refrigeration equipment, and only a few models are equipped with external cooling systems (excluding the passive cooling effect of airflow generated by the rotation of the cutter body itself). These cooling systems are complex in structure, have low energy efficiency, and insufficient lower temperature limit.

[0003] During crusher operation, the workpiece undergoes cutting and friction with the blade, causing heat accumulation on the blade and blade holder, resulting in an increase in temperature. As the temperature rises, the workpiece, which has a low melting point, may soften or melt, and the moving blade holder may experience "seizing," leading to high-temperature oxidation and blackening of the workpiece, reduced transmission belt life, and motor damage. Furthermore, the molten workpiece may adhere to or bind to the blade or blade holder, causing deformation or breakage of the blade or blade holder. Therefore, this application proposes a small bottom chiller suitable for crushers. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a small-sized bottom-mounted chiller to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a small bottom-mounted chiller, including a casing, a water tank at one end of the casing, a condenser at the other end of the casing, an evaporator inside the water tank, a plunger pump inside the casing near the water tank, the input of the plunger pump being connected to the water tank via a pipe, the output end of the plunger pump being provided with a chilled water inlet pipe penetrating the casing, and a chilled water return pipe being inserted into the top of one side of the casing, with one end of the chilled water return pipe inside the casing extending into the water tank;

[0006] A compressor is located inside the casing near the condenser. The condenser input end is connected to the compressor output end via a pipe. The compressor input end is connected to the evaporator output end via a pipe. The condenser output end is connected to the evaporator input end via a pipe.

[0007] A drying filter is provided on the pipe between the condenser output end and the evaporator input end.

[0008] The evaporator has an expansion tube at its input end, and the condenser output pipe is connected to the evaporator input end through the expansion tube.

[0009] The water tank is filled with chilled water, and the evaporator is used to cool the chilled water inside the water tank.

[0010] The chilled water inlet pipe is connected to the input end of the coolant pipe in the crusher cooling system; the chilled water return pipe is connected to the output end of the coolant pipe in the crusher cooling system.

[0011] A fan is provided at the end of the chassis near the condenser.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This invention uses a compressor to provide power, then delivers refrigerant to a condenser for cooling. The cooled refrigerant is then delivered to an evaporator, where it cools the water in a tank, turning it into chilled water. This chilled water is then delivered to the coolant pipe in the crusher's cooling system via a chilled water inlet pipe. Simultaneously, the heated coolant in the crusher's cooling system flows back to the tank via a chilled water return pipe, undergoing another cooling process in the evaporator. This cyclical system is used to cool the crusher, significantly alleviating the problem of abnormally high temperatures in conventional crushers, increasing the service life of the crusher and its blades, reducing maintenance costs, and lowering safety risks during production.

[0019] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] Reference Figure 1-4This utility model provides a small-sized bottom-mounted chiller, including a casing 1. A water tank 10 is located at one end of the casing 1, and a condenser 3 is located at the other end of the casing 1. An evaporator 7 is located inside the water tank 10. A plunger pump 11 is located inside the casing 1 near the water tank 10. The input of the plunger pump 11 is connected to the water tank 10 through a pipe. A chilled water inlet pipe 9 is located at the output end of the plunger pump 11, penetrating the casing 1. A chilled water return pipe 8 is inserted into the top of one side of the casing 1, and one end of the chilled water return pipe 8 inside the casing 1 extends into the water tank 10. A compressor 4 is located inside the casing 1 near the condenser 3. The input end of the condenser 3 is connected to the output end of the compressor 4 through a pipe. The input end of the compressor 4 is connected to the output end of the evaporator 7 through a pipe. The output end of the condenser 3 is connected to the input end of the evaporator 7 through a pipe. Power is supplied by compressor 4, and then the refrigerant is delivered to condenser 3. The condenser 3 cools the refrigerant, and then the cooled refrigerant is delivered to evaporator 7. The refrigerant flowing in evaporator 7 cools the water in water tank 10, thus lowering the temperature of the water in water tank 10 and turning it into chilled water. Then, the chilled water in water tank 10 is delivered to the coolant pipe in the crusher cooling system through chilled water inlet pipe 9. At the same time, the water in the coolant pipe of the crusher cooling system, after being heated, flows back to water tank 10 through chilled water return pipe 8 and is cooled again by evaporator 7. This cycle is used to cool the crusher, which greatly alleviates the problem of abnormal high temperature in conventional crushers, increases the service life of crushers and cutters, thereby reducing maintenance costs and lowering safety risks in the production process.

[0021] Furthermore, the coolant pipe in the crusher cooling system of this application belongs to the prior art, as shown in the utility model patent with application number 202321508434.3 entitled "A Crusher Cooling System".

[0022] A dryer filter 5 is installed on the pipe between the output end of the condenser 3 and the input end of the evaporator 7. The dryer filter 5 is located between the condenser 3 and the evaporator 7. Through the molecular sieve and filter screen inside the dryer filter 5, moisture is adsorbed and impurities are filtered to prevent refrigerant acidification and blockage inside the system caused by moisture.

[0023] The evaporator 7 is equipped with an expansion tube 6 at its inlet. The pipe at the outlet of the condenser 3 is connected to the inlet of the evaporator 7 through the expansion tube 6. The expansion tube 6 has a throttling function, which is used to adjust the flow rate of the high-pressure liquid refrigerant entering the evaporator 7 through the liquid pipeline and to maintain the pressure difference between the high-pressure side and the low-pressure side of the pipeline, so as to ensure that the refrigerant can evaporate at the desired low pressure in the evaporator 7, and at the same time, it can also condense in the condenser 3 under high pressure.

[0024] The water tank 10 is filled with chilled water, and the evaporator 7 is used to cool the chilled water inside the water tank 10.

[0025] The chilled water inlet pipe 9 is connected to the input end of the coolant pipe in the crusher cooling system; the chilled water return pipe 8 is connected to the output end of the coolant pipe in the crusher cooling system. The chilled water in the water tank 10 is transported to the coolant pipe in the crusher cooling system through the chilled water inlet pipe 9. At the same time, the water heated by the coolant pipe in the crusher cooling system flows back to the water tank 10 through the chilled water return pipe 8 and is cooled again by the evaporator 7. This cycle is used to cool the crusher, which greatly alleviates the problem of abnormal high temperature in conventional crushers, increases the service life of the crusher and the cutters, thereby reducing maintenance costs and lowering safety risks in the production process.

[0026] Among them, a fan 2 is provided on the side of the end of the chassis 1 near the condenser 3. The fan 2 is close to the condenser 3 and cools the condenser 3 through the fan 2.

[0027] Working principle: During use, the small bottom chiller is installed at the bottom of the crusher, and the chilled water inlet pipe 9 is connected to the input end of the coolant pipe in the crusher's cooling system; the chilled water return pipe 8 is connected to the output end of the coolant pipe in the crusher's cooling system. When the crusher is working, the fan 2, compressor 4, and plunger pump 11 are turned on to start the small bottom chiller. The compressor 4 provides power and then delivers the refrigerant to the condenser 3, where it is cooled. The cooled refrigerant is then delivered to the evaporator 7, where the refrigerant flowing in the evaporator 7 cools the refrigerant. The water in water tank 10 is cooled to reduce its temperature, turning it into chilled water. This chilled water is then transported through chilled water inlet pipe 9 to the coolant pipe in the crusher cooling system. Simultaneously, the cooled water in the crusher cooling system, after being heated, flows back to water tank 10 through chilled water return pipe 8 and is cooled again by evaporator 7. This cycle is repeated to cool the crusher, greatly alleviating the problem of abnormally high temperatures in conventional crushers, increasing the service life of the crusher and cutters, thereby reducing maintenance costs and safety risks during production.
