Description

Technical Field

[0001] This utility model relates to the field of granulation equipment technology, and in particular to a small automatic granulation 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 include two types: water cooling and air cooling. Air cooling devices use a fan to continuously blow airflow to cool the raw material strips, while water cooling devices immerse the raw material strips in a water tank for cooling. Water cooling and air cooling each have their advantages. In comparison, water cooling devices have higher heat dissipation efficiency than air cooling devices, and water cooling devices also occupy less space.

[0004] Although water cooling devices occupy a small area, the water in the tank will quickly heat up and evaporate after contact with the hot raw material strips. Moreover, a large amount of water will adhere to the raw material strips leaving the tank, which will further increase the amount of water required for cooling. Therefore, there is a need for an automatic granulation device that can reduce water consumption and improve cooling efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a small-scale automatic granulation device, which aims to solve the problem of high water consumption in the water cooling device of existing granulation equipment.

[0007] The cooling device includes a frame, a water-cooling tank, a circulation assembly, and a return water assembly. The water-cooling tank is mounted on the frame. The circulation assembly and the return water assembly are used for circulating cooling water and recovering moisture from the raw material strips, respectively. The return water assembly includes a return pool, a base, a scraper, and an air outlet. The return pool is mounted on the frame and is connected to the water-cooling tank. Multiple sets of bases are mounted on the return pool, and each set of bases is equipped with a scraper and an air outlet.

The wiper blade is provided with L-shaped grooves corresponding to the locking protrusions. The wiper blade is provided with handles, and the base is provided with detachable pressure rods, which are located on the side where the air exhaust is installed.

[0009] Furthermore, a support roller is installed on the reflux tank, and a dehumidifying fan assembly is installed above the support roller; a guide trough is installed on the side of the reflux tank away from the water cooling tank.

[0010] Furthermore, the circulation component includes a circulation pump, circulation water pipes, and a radiator. Both the radiator and the circulation pump are mounted on the frame. The circulation pump is connected to the water cooling tank and the radiator respectively through the circulation water pipes. The radiator is connected to the water cooling tank through the circulation water pipes. The water flow direction in the water cooling tank is opposite to the movement direction of the raw material strip. A cooling fan assembly is installed on the radiator.

[0011] Furthermore, the rack is equipped with an air guide chamber, which has an air inlet and an air outlet. The air inlet is located near the radiator, and the air outlet is located above the recirculation pool.

The multiple sets of support rods are evenly installed in the water cooling tank. A set of guide rollers and a pressure roller are installed at each end of the water cooling tank. The pressure rollers are detachably installed in the water cooling tank. Multiple sets of cover plates are provided on the water cooling tank, and each set of cover plates is equipped with a handle.

[0013] Furthermore, a traction assembly is provided on the reflux pool. The traction assembly includes a traction seat, an auxiliary roller, a drive roller, a limiting guide rod, a limiting elastic element, and a locking sleeve. The traction seat is installed on the reflux pool, and the limiting guide rod is installed on the traction seat. Two sets of slides are installed on the limiting guide rod, and the slides are used to install the auxiliary roller and the drive roller respectively.

Detailed Implementation

[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 16 As shown, this utility model provides a small automatic granulation device, including an extrusion device 1, a cooling device 2 and a cutting device 3 arranged in sequence. The extrusion device 1 is used to melt the raw material and extrude the raw material strip, the cooling device 2 is used to cool the extruded raw material strip, and the cutting device 3 is used to cut the cooled raw material strip.

[0038] The cooling device 2 includes a frame 20, a water-cooling tank 21, a circulation assembly 22, and a return water assembly 23. The water-cooling tank 21 is mounted on the frame 20. The circulation assembly 22 and the return water assembly 23 are used for circulating cooling water and recovering moisture from the raw material strips, respectively. The return water assembly 23 includes a reflux pool 230, a base 231, a scraper 232, and an air exhaust 233. The reflux pool 230 is mounted on the frame 20 and is connected to the water-cooling tank 21. Multiple sets of bases 231 are mounted on the reflux pool 230, and each set of bases 231 is equipped with a set of scraper 232 and an air exhaust 233. The water plate 232 is provided with multiple sets of scraper grooves 2320, which are used to scrape the water off the raw material strip. The scraper grooves 2320 are provided with scraper holes 2321. The air exhaust 233 is provided with a magnetic base 2331, an air nozzle 2330 and a plug interface 2332. The air exhaust 233 is attached to the base 231 by the magnetic base 2331. The air nozzle 2330 on the air exhaust 233 is close to the scraper grooves 2320. The plug interface 2332 is located on the side of the air exhaust 233. The frame 20 is also provided with an air pump 28, which is detachably connected to the plug interface 2332 through a hose.

[0039] After the raw material is processed by the extruder, the hot raw material strip falls into the water cooling tank 21. The water in the water cooling tank 21 needs to completely submerge the raw material strip to ensure optimal cooling. After cooling, the raw material strip needs to be dried for subsequent storage and processing. With the above design, the raw material strip coming out of the water cooling tank 21 passes through the scraper holes 2321 on the scraper trough 2320. The water adhering to the raw material strip is scraped off by the scraper trough 2320. The scraped water collects on the scraper trough 2320 and drips into the return pool 230, and then flows back from the return pool 230 to the water cooling tank 21, reducing the waste of cooling water. The airflow output by the air pump 28 is blown towards the scraper trough 2320 under the guidance of the air outlet 233. Under the action of the airflow from the air outlet 233, the water scraped off by the scraper trough 2320 is blown into the return pool 230, avoiding water splashing.

[0040] In this embodiment, the scraper groove 2320 is made of silicone material, which has good corrosion resistance and flexibility, and can effectively scrape off the moisture on the raw material strip without damaging the raw material strip.

[0041] In this embodiment, a cross-shaped opening is provided around the scraper hole 2321, and the opening above the scraper hole 2321 is connected to the top of the scraper plate 232. The operator can directly press the raw material strip into the scraper hole 2321 through the opening above the scraper hole 2321.

[0042] In this embodiment, a mounting base 2310 is provided on the base 231, and the mounting base 2310 is located on both sides of the base 231. The wiper blade 232 is mounted on the mounting base 2310. The mounting base 2310 is provided with a locking protrusion 2311, and the wiper blade 232 is provided with an L-shaped groove 2323 corresponding to the locking protrusion 2311. The wiper blade 232 is provided with a handle 2322, and the base 231 is provided with a detachable pressure rod 234, which is located on the side where the air exhaust 233 is installed.

[0043] Through the above design, the locking protrusion 2311 can be locked into the L-shaped groove 2323, ensuring that the wiper blade 232 can be locked onto the base 231. When the wiper blade 232 needs to be installed, the operator can hold the handle 2322, press the locking protrusion 2311 into the L-shaped groove 2323, and then push the wiper blade 232 so that the locking protrusion 2311 is locked into the innermost end of the L-shaped groove 2323. The pressure rod 234 on the base 231 can limit the height of the raw material strip, ensuring that the raw material strip can always be aligned with the wiper hole 2321 during movement.

[0044] In this embodiment, a support roller 25 is provided on the reflux pool 230, and a dehumidifying fan assembly 26 is installed above the support roller 25; a guide groove 29 is installed on the side of the reflux pool 230 away from the water cooling tank 21.

[0045] With the above design, the support roller 25 on the return pool 230 can flatten the raw material strip, which is convenient for subsequent air drying operations. The dehumidifying fan group 26 can output high-speed airflow to dry the residual moisture on the raw material strip. The guide groove 29 is used to guide the raw material strip and make it converge into the cutting device 3.

[0046] In this embodiment, the circulation component 22 includes a circulation pump 220, a circulation water pipe 221, and a radiator 222. Both the radiator 222 and the circulation pump 220 are mounted on the frame 20. The circulation pump 220 is connected to the water cooling tank 21 and the radiator 222 respectively through the circulation water pipe 221. The radiator 222 is connected to the water cooling tank 21 through the circulation water pipe 221. The water flow direction in the water cooling tank 21 is opposite to the movement direction of the raw material strip. A cooling fan assembly 223 is provided on the radiator 222.

[0047] In this embodiment, the frame 20 is provided with an air guide chamber 24, and the air guide chamber 24 is provided with an air inlet 240 and an air outlet 241. The air inlet 240 is located near the heat sink 222, and the air outlet 241 is located above the reflux pool 230.

[0048] After heat exchange with the raw material strips, the water in the water-cooling tank 21 becomes hotter, reducing its cooling effect. Simultaneously, the evaporation rate of the high-temperature water is greater, leading to increased water consumption. Through the above design, the circulating pump 220 can extract the high-temperature water from the water-cooling tank 21 and pump it to the radiator 222. The airflow from the cooling fan assembly 223 carries away a significant amount of heat as it passes through the radiator 222, lowering the water temperature to room temperature. The cooled water then returns to the water-cooling tank 21 for repeated cooling. The airflow from the cooling fan assembly 223 is converted into hot air after passing through the radiator 222. Guided by the air guide chamber 24, the hot air is blown above the return pool 230 to dry the scraped raw material strips. Utilizing the radiator 222 for heat exchange ensures that the water temperature in the water-cooling tank 21 remains within a suitable range, guaranteeing sufficient cooling. The air guide chamber 24 improves the utilization efficiency of excess heat, increasing the drying efficiency of the raw material strips while reducing energy waste.

[0049] In this embodiment, the water cooling tank 21 is provided with two sets of guide rods 210, two sets of pressure rollers 211 and multiple sets of support rods 212. The multiple sets of support rods 212 are evenly installed in the water cooling tank 21. A set of guide rods 210 and a pressure roller 211 are respectively installed at both ends of the water cooling tank 21. The pressure rollers 211 are detachably installed in the water cooling tank 21. Multiple sets of cover plates 213 are provided on the water cooling tank 21, and each set of cover plates 213 is provided with a handle 214.

[0050] Through the above design scheme, the guide roller 210 can guide the raw material strip extruded from the extrusion device 1, preventing the raw material strip from scraping against the edge of the water cooling tank 21. The pressure roller 211 can press the raw material strip into the water, preventing the raw material strip from leaving the water surface during the traction process and affecting the cooling effect. The support rod 212 in the water cooling tank 21 can support the raw material strip to suspend in the water, increasing the contact area between the raw material strip and the water flow, and improving the cooling efficiency of the raw material strip. The cover plate 213 on the water cooling tank 21 can intercept the evaporated water vapor. After the evaporated water vapor touches the cover plate 213, it will condense into small water droplets and then drip back into the water cooling tank 21, reducing water waste. The handle 214 on the cover plate 213 can make it easy for the staff to lift the cover plate 213 for cleaning.

[0051] In this embodiment, a traction assembly 27 is provided on the reflux pool 230. The traction assembly 27 includes a traction seat 272, an auxiliary roller 270, a drive roller 271, a limiting light rod 273, a limiting elastic element 275, and a locking sleeve. The traction seat 272 is installed on the reflux pool 230, and the limiting light rod 273 is installed on the traction seat 272. Two sets of slides 274 are installed on the limiting light rod 273. The slides 274 are used to install the auxiliary roller 270 and the drive roller 271, respectively. The limiting elastic element 275 is a spring. The limiting elastic element 275 is sleeved on the limiting light rod 273. One end of the limiting elastic element 275 abuts against the traction seat 272, and the other end abuts against the slide 274. The locking sleeve is installed on both sides of the drive roller 271.

[0052] In this embodiment, the locking sleeve includes a locking screw 276 and a locking plate 277. The locking screw 276 is installed at both ends of the drive roller 271 through a threaded seat, and the locking plate 277 is pressed against the traction seat 272 by the locking screw 276.

[0053] Through the above design scheme, under the action of the auxiliary roller 270 and the drive roller 271, the raw material strip can be actively pulled, ensuring that the raw material strip can move stably in the cooling device 2. In this embodiment, the drive roller 271 is preferably an external rotor direct-drive electric roller. During the processing, the operator can first loosen the locking screw 276 to allow the drive roller 271 to move freely on the limiting rod 273, place the raw material strip between the drive roller 271 and the auxiliary roller 270, then press down the drive roller 271 until the raw material strip is clamped, and finally rotate the locking screw 276 to make the locking piece 277 lock the traction seat 272, ensuring that the drive roller 271 can be fixed on the traction seat 272.

[0054] The small automatic granulation equipment provided by this utility model, compared with the prior art, has the following advantages: the raw material strips extruded from the extrusion device 1 fall into the water cooling tank 21. After being cooled by the water cooling tank 21, the raw material strips come to the water return component 23. When passing through the scraper 232, the water attached to the raw material strips will be scraped off by the scraper 2320 and drip into the return pool 230, reducing the waste of water resources; the water vapor evaporated in the water cooling tank 21 condenses into small water droplets when it comes into contact with the cover plate 213. After reaching a certain amount, it drips back into the water cooling tank 21, further reducing the waste of water resources.

[0055] Where there is no conflict, the above embodiments and features can be combined with each other.

[0056] 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.
