Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, specifically to a cooling device for processing pig feed pellets. Background Technology

[0002] Cooling equipment for pig feed pellet processing is mainly used to cool pig feed pellets. In the pig feed processing production line, the pig feed pellets are at a high temperature after being processed by the pellet mill. In order to improve the quality of the feed and maintain its stability, they need to be cooled.

[0003] Currently, the cooling of pig feed pellets is mostly achieved by using blowers (i.e., air cooling technology). Although this is the traditional mainstream solution, it has the following drawbacks: 1. When the ambient temperature exceeds 30℃, the air drawn in by the blower is itself hot and has a weak water-holding capacity, resulting in insufficient cooling of the pellets. This requires extending the cooling time or increasing the air volume, further increasing energy consumption. 2. If the pellets are unevenly distributed in the cooler (e.g., piled up in mounds), the cold air blown out by the blower can only penetrate the surface pellets. The middle and bottom pellets are not cooled sufficiently, resulting in a temperature difference of 8-10℃ at the discharge. Some pellets are still in a high-temperature and high-humidity state, making them prone to mold. Utility Model Content

[0004] The purpose of this invention is to provide a cooling device for processing pig feed pellets, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for processing pig feed pellets, comprising a mixing tank and a PLC controller disposed outside the mixing tank. A tank cover is bolted to the top of the mixing tank, and an inlet pipe is connected to the inner wall of the tank cover. A discharge pipe is connected to the bottom of the mixing tank. Control valves are installed on the inner walls of both the inlet and discharge pipes. An agitator is disposed inside the mixing tank. The device also includes:

[0006] A cavity is formed in the inner wall of the mixing tank, and an insulation layer is fixed to the outer side of the mixing tank;

[0007] A water-cooling component is installed inside the mixing tank to absorb heat from the tank. The water-cooling component includes a coiled tube that is annularly wound around the inner wall of the cavity and a liquid storage tank located on the outside of the mixing tank. A liquid delivery device is provided between the coiled tube and the liquid storage tank, and a cooling device is provided on the top of the liquid storage tank.

[0008] Preferably, the infusion device includes a first pump and a second pump with flanges connected to both ends of the coil. The inlet end of the first pump and the outlet end of the second pump are respectively connected to a pumping pipe and a drain pipe with flanges. The pumping pipe is connected to the inner wall of the storage tank.

[0009] Preferably, the cooling component includes a heat dissipation box fixed to the top of the liquid storage tank, a diversion box is detachably installed on the top of the heat dissipation box, and the drain pipe is connected to the inner wall of the diversion box.

[0010] Preferably, a wire hole is provided on one side of the heat sink, and heat dissipation holes are provided on both opposite sides of the heat sink.

[0011] Preferably, the inner wall of the heat sink is provided with two serpentine tubes, the two ends of which are connected to the distribution box and the liquid storage box, respectively.

[0012] Preferably, a double-sided fan is provided between the two serpentine tubes, and the double-sided fan is detachably installed on the inner wall of the heat sink.

[0013] Preferably, the water-cooling assembly further includes a replenishment pipe and a waste pipe connected to the inner wall of the liquid storage tank, and both the replenishment pipe and the waste pipe are provided with shut-off valves on their inner walls.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention offers several advantages by replacing traditional air-cooling technology with water-cooled components. Since the effect of air cooling is highly dependent on ambient temperature, the water-cooling system can stably cool the particles by regulating the temperature of the circulating water, unaffected by high temperatures or humidity in summer. Furthermore, while the coolant is circulating and cooling, the feed in the mixing tank is stirred by the agitator, preventing uneven cooling and thus improving feed processing efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 As shown, a cooling device for processing pig feed pellets includes a mixing tank 1 and a PLC controller 2 disposed on the outside of the mixing tank 1. The mixing tank 1 is equipped with a water cooling component 3 for absorbing heat inside the tank. A tank cover 4 is bolted to the top of the mixing tank 1. A feed pipe 5 is connected to the inner wall of the tank cover 4. A discharge pipe 6 is connected to the bottom of the mixing tank 1. Control valves 7 are disposed on the inner walls of both the feed pipe 5 and the discharge pipe 6. An agitator 8 is disposed inside the mixing tank 1.

[0024] In use, the operator connects the feed pipe 5 to the discharge pipe of the pig feed pellet production, allowing the feed to enter the mixing tank 1 through the feed pipe 5. The feed is stirred in the mixing tank 1 by the stirring component 8. At the same time, the heat of the feed is carried away by the heat absorption effect of the water cooling component 3, so that the feed pellets achieve a cooling effect. The stirring component 8 consists of a servo motor and a stirring rod. The servo motor is controlled and started by the PLC controller 2, which drives the stirring rod to rotate and stir the feed, making the feed cool more evenly. The mixing tank 1 can be sealed by the tank cover 4, and the stirring rod can be easily opened for maintenance. The discharge pipe 6 connected to the bottom of the mixing tank 1 can facilitate the discharge of the cooled feed. The control valve 7 installed inside the feed pipe 5 and the discharge pipe 6 can facilitate the control of the opening and closing of the feed pipe 5 and the discharge pipe 6.

[0025] The inner wall of the mixing tank 1 has a cavity 11, and the outer side of the mixing tank 1 is fixed with a heat insulation layer 12.

[0026] A cavity 11 is opened in the inner wall of the mixing tank 1, which facilitates the installation of a coil 31 inside the cavity 11. The coil 31 can be coiled around the inner wall of the mixing tank 1 to absorb and remove the heat of the feed inside the mixing tank 1. By setting an insulation layer 12 on the outside of the mixing tank 1, the external ambient temperature can be prevented from being transferred into the cavity 11.

[0027] The water-cooling assembly 3 includes a coil 31 annularly wound around the inner wall of the cavity 11 and a liquid storage tank 32 disposed outside the mixing tank 1. A liquid delivery component 33 is disposed between the coil 31 and the liquid storage tank 32, and a cooling component 34 is disposed on the top of the liquid storage tank 32. The liquid delivery component 33 includes a first liquid pump 331 and a second liquid pump 332 with flanges connected to both ends of the coil 31. The inlet end of the first liquid pump 331 and the outlet end of the second liquid pump 332 are respectively flanged to a liquid extraction pipe 333 and a liquid discharge pipe 334. The liquid extraction pipe 333 communicates with the inner wall of the liquid storage tank 32. The cooling component 34 includes a heat dissipation box 341 fixed to the top of the liquid storage tank 32. A diverter is detachably installed on the top of the heat dissipation box 341. The heat sink 342 has a drain pipe 334 connected to the inner wall of the distribution box 342; a wire hole 3411 is provided on one side of the heat sink 341, and heat dissipation holes 3412 are provided on both opposite sides of the heat sink 341; two serpentine tubes 343 are mirror-mounted on the inner wall of the heat sink 341, and the two ends of the serpentine tubes 343 are connected to the distribution box 342 and the liquid storage tank 32 respectively; a double-sided fan 344 is provided between the two serpentine tubes 343, and the double-sided fan 344 is detachably installed on the inner wall of the heat sink 341; the water cooling component 3 also includes a replenishment pipe 35 and a waste liquid pipe 36 connected to the inner wall of the liquid storage tank 32, and a shut-off valve 37 is provided on the inner wall of both the replenishment pipe 35 and the waste liquid pipe 36.

[0028] By installing a coil 31 inside the cavity 11, coolant flow is facilitated. The coolant flowing through the cavity 11 absorbs and carries away heat from the mixing tank 1. A storage tank 32 facilitates coolant storage and recycling. The coolant in the storage tank 32 needs to be replaced periodically, the specific replacement time depending on the coolant's lifespan. A delivery component 33 facilitates coolant circulation, keeping the coolant at a consistently low temperature to absorb heat from the mixing tank 1. A cooling component 34 facilitates cooling the heat-absorbing coolant by blowing air through it, lowering its temperature. During use, the coolant that has absorbed heat in the coil 31 is pumped through a second pump 332 and discharged from the drain pipe 334 to... Inside the distribution box 342, the coolant gathers and then flows to two serpentine tubes 343. The double-sided fan 344 is connected to an external power supply through the wiring hole 3411. After the double-sided fan 344 is started by the PLC controller 2, it blows air onto the two serpentine tubes 343. The double-sided fan 344 can blow air in two opposite directions at the same time. The working principle of the double-sided fan 344 has been disclosed in the prior art and will not be described in detail here. The cooling effect is achieved by the flow of air through the serpentine tubes 343 and the blowing of the fan. The hot air blown out is discharged from the heat dissipation hole 3412. The cooled coolant enters the storage tank 32. Finally, the coolant in the storage tank 32 is pumped back into the coil 31 by the pump 331 and the pump pipe 333 to achieve a circulation effect. The coolant in the storage tank 32 can be periodically replaced by setting up a replenishment pipe 35 and a waste pipe 36. The on / off valve 37 can be used to control the flow of the replenishment pipe 35 and the waste pipe 36. It should be noted that the PLC controller 2 is electrically connected to the servo motor, the first pump 331, the second pump 332, and the double-sided fan 344 via wires. The specific structure, working principle, control method, and spatial arrangement of these technical features can be selected using conventional methods in this field, and this technical solution will not be further elaborated in detail.
