Description

Technical Field

[0001] This utility model relates to the field of granulation equipment technology, and in particular to a rapid cooling device. Background Technology

[0002] Granulation equipment is a device that melts raw materials and processes them into granular materials. Granulation equipment typically includes an extruder, a cooling device, and a cutting machine. The extruder is used to melt the raw materials and extrude raw material strips, the cooling device is used to quickly cool the raw material strips, and the cutting machine is used to cut the raw material strips into granular materials.

[0003] Cooling devices typically come in two types: air cooling and water cooling. Air cooling has lower efficiency, while water cooling has higher efficiency, but it requires a longer water tank for cooling, which increases the footprint of the granulation equipment. Furthermore, the water-cooled raw material strips need to be drained and dried afterward, so a certain distance needs to be left in the production line for draining before adding a drying device, which will undoubtedly further increase the footprint of the equipment.

[0004] Therefore, there is a need for a cooling device that can quickly dissipate heat from the raw material strips and reduce the floor space required. Utility Model Content

[0005] The purpose of this invention is to provide a rapid cooling device to solve the problem of the large footprint of water-cooled equipment in existing granulation devices.

[0006] To achieve the above objectives, this utility model provides a rapid cooling device, including a frame with a water-cooled tank mounted on it. The frame also includes a water-cooling assembly and a refrigeration assembly. The water-cooling assembly includes a water flow radiator, a water flow fan assembly, a return water pump, a cold water tank, and a supply water pump. The water-cooled tank is fixedly mounted on the frame, with its inlet located at the end of the frame and its outlet at the front. A water flow radiator is installed at the bottom of the water-cooled tank, and the water flow fan assembly is mounted on it. The cold water tank, return water pump, and supply water pump are all mounted on the frame. The water-cooled tank is connected to the water flow radiator. The return water pump draws water from the water-cooled tank into the water flow radiator and then pumps the water from the radiator back to the cold water tank. The supply water pump pumps water from the cold water tank into the water-cooled tank. The refrigeration assembly cools the water in the cold water tank.

[0007] Furthermore, the refrigeration components include a compressor, an evaporator, a condenser, and a condenser cooling fan assembly. The compressor and condenser are both mounted on a frame, the condenser cooling fan assembly is mounted on the condenser, and the evaporator is mounted in a chilled water tank. The condenser and evaporator are respectively connected to the compressor.

[0008] Furthermore, an air guide frame is provided at the end of the rack, and a first air guide chamber and a second air guide chamber are provided in the air guide frame. The water flow heat dissipation vent is located in the first air guide chamber, and the condenser is located in the second air guide chamber.

[0009] Furthermore, heating elements are installed at the air outlets of both the first and second air guide chambers.

[0010] Furthermore, a guiding component is provided in the water cooling tank. The guiding component includes several support rollers, pressure rollers and guide rollers. The guide rollers are located at the water outlet end of the water cooling tank, the pressure rollers are detachably installed at the water inlet end of the water cooling tank, and several sets of support rollers are evenly installed at the bottom of the water cooling tank.

[0011] Furthermore, the water cooling tank has sliding grooves on both sides, and a cover assembly is installed on the sliding grooves. The cover assembly includes a sliding cover and an extension cover. The sliding cover has pulleys on both sides, and the pulleys are slidably connected in the sliding grooves. The extension cover is slidably installed in the sliding cover. A limit seat is provided on the sliding groove to limit the sliding of the sliding cover. A handle is provided on the sliding cover.

[0012] Furthermore, a scraper assembly is provided at the water inlet of the water cooling tank. The scraper assembly includes a scraper strip and a scraper blade. The scraper strip can be detachably installed on the slide. Two sets of scraper blades are provided on the scraper strip. Several scraper grooves are provided on the scraper blades. Reinforcing ribs are provided on both sides of the scraper grooves.

[0013] Furthermore, the surface of the cold water tank is equipped with an insulation layer.

[0014] The rapid cooling device provided by this utility model, compared with the prior art, involves the water flow after cooling and temperature reduction entering the inlet of the water cooling tank under the pumping of the water supply pump. The high-temperature water flow after cooling the raw material strip enters the water flow heat dissipation for heat dissipation, and then returns to the cold water tank for re-cooling. When the raw material strip coming out of the water cooling tank passes through the scraper, the scraper can scrape off most of the residual water on the raw material strip, and the remaining water on the raw material strip will be dried by the hot air output from the air guide frame. This reduces the floor space required for draining and drying while ensuring cooling efficiency. Attached Figure Description

[0035] The present invention will be described in detail below with reference to specific embodiments.

[0036] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0037] like Figures 1 to 10 As shown, this utility model provides a rapid cooling device, including a frame 1, a water-cooled tank 2 mounted on the frame 1, and a water-cooling assembly 3 and a refrigeration assembly 4. The water-cooling assembly 3 includes a water flow heat sink 33, a water flow heat sink fan assembly 34, a return water pump 31, a cold water tank 30, and a supply water pump 32. The water-cooled tank 2 is fixedly installed on the frame 1, and the water inlet 20 of the water-cooled tank 2 is located at the end of the frame 1 (wherein, in the granulation equipment, the end of the frame 1 closest to the extruder is the front end of the frame 1, and the end of the frame 1 closest to the cutting machine is the end end of the frame 1). The water outlet of the water-cooled tank 2... End 21 is located at the front end of frame 1; a water flow heat dissipation radiator 33 is installed at the bottom of the water cooling tank 2, and a water flow heat dissipation fan assembly 34 is installed on the water flow heat dissipation radiator 33. The cold water tank 30, return water pump 31 and supply water pump 32 are all installed on frame 1. The water cooling tank 2 is connected to the water flow heat dissipation radiator 33. The return water pump 31 is used to draw water from the water cooling tank 2 into the water flow heat dissipation radiator 33, and then pump the water from the water flow heat dissipation radiator 33 to the cold water tank 30. The supply water pump 32 is used to pump the water from the cold water tank 30 to the water cooling tank 2. The refrigeration component 4 is used to cool the water in the cold water tank 30.

[0038] Through the above design scheme, the water in the cold water tank 30 is cooled by the refrigeration component 4 and then pumped by the water supply pump 32 to the inlet 20 of the water cooling tank 2. The flow direction of the water in the water cooling tank 2 is opposite to the movement direction of the raw material strip. Therefore, the water temperature at the inlet 20 of the water cooling tank 2 is lower, while the water temperature at the outlet 21 of the water cooling tank 2 is higher. The raw material strip extruded from the extruder first comes into contact with the higher temperature water flow. The temperature difference between the newly extruded high-temperature raw material strip and the high-temperature water flow is small, which can avoid the deformation of the raw material strip due to thermal expansion and contraction caused by rapid cooling.

[0039] The return water pump 31 can draw the high-temperature water flow from the water-cooled tank 2, so that the high-temperature water flow enters the cold water tank 30 after passing through the water flow heat dissipation 33 and the return water pump 31. Under the action of the water flow heat dissipation fan group 34, the high-temperature water flow passing through the water flow heat dissipation 33 can be rapidly cooled, so that the temperature of the water flow returning to the cold water tank 30 is close to the room temperature. The room temperature water flow is further cooled by the action of the refrigeration component 4, so that the room temperature water in the cold water tank 30 is converted into cold water. The water supply pump 32 then pumps the cold water to the water inlet 20 of the water-cooled tank 2 to continue the cooling work.

[0040] In this embodiment, the cold water tank 30 is provided with multiple sets of staggered guide plates. The guide plates can guide the flow direction of the water flow and prevent the room temperature water that has just flowed back into the cold water tank 30 from being directly extracted without being cooled.

[0041] In this embodiment, the refrigeration assembly 4 includes a compressor 40, an evaporator 41, a condenser 42, and a condenser cooling fan assembly 43. The compressor 40 and the condenser 42 are both mounted on the frame 1. The condenser cooling fan assembly 43 is mounted on the condenser 42. The evaporator 41 is mounted in the cold water tank 30. The condenser 42 and the evaporator 41 are respectively connected to the compressor 40.

[0042] Through the above design scheme, the refrigeration assembly 4, composed of condenser 42, evaporator 41 and compressor 40, can quickly cool the water flow in cold water tank 30, improve the cooling efficiency of the water flow in water cooling tank 2, and effectively reduce the length required for water cooling tank 2 by lowering the water temperature to improve cooling efficiency, thereby effectively reducing the floor space occupied by the cooling device.

[0043] In this embodiment, an air guide frame 5 is provided at the end of the frame 1. The air guide frame 5 is provided with a first air guide chamber 50 and a second air guide chamber 51. The water flow heat dissipation radiator 33 is located in the first air guide chamber 50, and the condenser 42 is located in the second air guide chamber 51.

[0044] In this embodiment, heating elements 52 are provided at the air outlets of both the first air guide chamber 50 and the second air guide chamber 51.

[0045] Through the above design scheme, the airflow blown out by the water flow cooling fan group 34 passes through the water flow cooling radiator 33, and the airflow carries away the heat of the water flow cooling radiator 33 and turns it into hot air at a higher temperature. Under the guidance of the first air guide chamber 50, the hot air blows towards the raw material strip coming out of the water cooling tank 2 to perform preliminary drying of the raw material strip. The airflow blown out by the condenser cooling fan group 43 will also be converted into hot air after cooling the condenser 42. The hot air output by the condenser cooling fan group 43 will enter the second air guide chamber 51. Under the guidance of the second air guide chamber 51, the hot air will continue to perform secondary drying of the raw material strip to ensure that the raw material strip is in a dry state when it enters the cutting machine.

[0046] The heating elements 52 at the air outlets of the first air guide chamber 50 and the second air guide chamber 51 can be used to supplement heat. In the initial stage, the temperature of the condenser 42 and the water flow heat sink 33 is low, and the output hot air cannot achieve the best drying effect. At this time, the heating elements 52 need to be activated to increase the temperature of the hot air to ensure the drying effect. After a certain period of operation, the temperature of the condenser 42 and the water flow heat sink 33 will rise, and the temperature of the hot air entering the air guide frame 5 will also increase. At this time, the heating elements 52 can be stopped to reduce power consumption.

[0047] In this embodiment, a guide component 7 is provided in the water cooling tank 2. The guide component 7 includes several support rollers 72, pressure rollers 71 and guide rollers 70. The guide rollers 70 are located at the water outlet end 21 of the water cooling tank 2. The pressure rollers 71 are detachably installed at the water inlet end 20 of the water cooling tank 2. Several sets of support rollers 72 are evenly installed at the bottom of the water cooling tank 2.

[0048] The support roller 72 in the water cooling tank 2 can support the raw material strip entering the water cooling tank 2 and prevent the raw material strip from touching the bottom of the water cooling tank 2 and causing wear; the guide roller 70 can be used to guide the raw material strip extruded from the extruder; the pressure roller 71 is used to press down the raw material strip near the water inlet end 20 to prevent it from being washed away by the water jet from the water inlet end 20.

[0049] In this embodiment, sliding grooves 22 are provided on both sides of the water cooling tank 2, and a cover assembly 6 is installed on the sliding grooves 22. The cover assembly 6 includes a sliding cover 60 and an extension cover 61. Pulleys 63 are provided on both sides of the sliding cover 60, and the pulleys 63 are slidably connected in the sliding grooves 22. The extension cover 61 is slidably installed in the sliding cover 60. A limiting seat is provided on the sliding grooves 22 to limit the sliding of the sliding cover 60. A handle 62 is provided on the sliding cover 60.

[0050] The water temperature after cooling the raw material strips is often high, which causes a large amount of water vapor to evaporate, reducing the water flow for circulating cooling. Users need to replenish the water flow from time to time to ensure sufficient water flow for cooling operations. Through the above design, the sliding cover 60 and the extension cover 61 can block most of the water vapor evaporating from the water cooling tank 2. The water vapor gathers into water droplets on the sliding cover 60 and the extension cover 61 and then drips into the water cooling tank 2, reducing evaporation consumption and reducing the time users need to add water. When it is necessary to clean the water cooling tank 2, the user can push the sliding cover 60 to slide on the slide 22, so that the extension cover 61 slides under the sliding cover 60, reducing the coverage area of ​​the cover assembly 6 and making it easier for the user to clean. The user can also remove the sliding cover 60 and the extension cover 61 from the slide 22 using the handle 62, and put the cover assembly 6 back on after cleaning the water cooling tank 2.

[0051] In this embodiment, a scraper assembly 8 is provided at the water inlet 20 of the water-cooled tank 2. The scraper assembly 8 includes a scraper strip 80 and a scraper blade 81. The scraper strip 80 is detachably installed on the slide groove 22. Two sets of scraper blades 81 are provided on the scraper strip 80. Several scraper grooves 82 are provided on the scraper blades 81. Reinforcing ribs 83 are provided on both sides of the scraper grooves 82.

[0052] After being cooled by water, the raw material strip will have a large amount of water attached to it, which will further increase the amount of water required for cooling. With the above design, the scraper groove 82 on the scraper 81 can scrape off the water on the raw material strip and let it fall back into the water cooling tank 2. The reinforcing ribs 83 on both sides of the scraper groove 82 can increase the structural strength of the scraper 81 and prevent the scraper 81 from being severely deformed, which would affect the scraping efficiency.

[0053] In this embodiment, the wiper blade 81 is made of silicone material.

[0054] In this embodiment, the scraper groove 82 is cross-shaped, and a round hole is provided in the center of the cross shape.

[0055] In this embodiment, a heat insulation layer is provided on the surface of the cold water tank 30. The heat insulation layer is made of heat insulation foam and can keep the cold water in the cold water tank 30 warm, reducing the loss of temperature.

[0056] The rapid cooling device provided by this utility model, compared with the prior art, has the following features: after cooling, the water flow enters the inlet 20 of the water cooling tank 2 under the pumping of the water supply pump 32; the high-temperature water flow after cooling the raw material strip enters the water flow heat dissipation duct 33 for heat dissipation, and then returns to the cold water tank 30 for re-cooling; when the raw material strip coming out of the water cooling tank 2 passes through the scraper 80, the scraper 82 can scrape off most of the residual water on the raw material strip, and the remaining water on the raw material strip will be dried by the hot air output from the air guide frame 5, which reduces the floor space required for draining and drying while ensuring cooling efficiency.

[0057] Where there is no conflict, the above embodiments and features can be combined with each other.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
