Description

Technical Field

[0001] This utility model relates to the field of rubber cooling technology, specifically an automatic control cooling machine. Background Technology

[0002] When processing rubber or plastic granules, it is necessary to cool down the materials at high temperatures for convenient storage to avoid danger caused by excessive heat. A cooling machine is required for this cooling process.

[0003] Chinese Patent No. 201220540680.2 discloses a material cooling machine designed to solve the problems of material sticking to the inner wall of the shell and poor cooling effect in existing material cooling machines. The material cooling machine includes a hollow shell, an inlet and an outlet located on the shell. Several cooling channels and several heating channels are spaced apart on the shell. The cooling channels contain cooling fluid for cooling the material inside the shell. The heating channels, through which hot fluid is introduced, heat the material that has adhered to the inner wall of the shell due to excessive cooling, thus separating it from the shell.

[0004] When this utility model is in use, water vapor in the air will pre-cool and adhere to the material when the temperature drops, resulting in increased humidity of the material. At the same time, the material still needs to be transported and stored after cooling, which is very inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide an automatically controlled cooling machine to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic control cooling machine, including a cooling device; the cooling device consists of a material cylinder and an inner cylinder, the inner cylinder being welded inside the material cylinder, a turning mechanism being installed inside the material cylinder at the inner section of the inner cylinder, an external cooling mechanism being installed on the outside of the material cylinder, an internal cooling mechanism being installed on the outside of the inner cylinder, a cover being rotatably installed at the upper inlet of the material cylinder, a conical cover being installed at the bottom of the material cylinder, a discharge pipe being installed at the bottom of the conical cover, a control valve being installed on the upper side of the discharge pipe, and a support leg being installed at the bottom of the material cylinder.

[0007] Preferably, the internal cooling mechanism consists of a circulation pipe, an inlet pipe, and an outlet pipe. The circulation pipe is wound around the outside of the inner cylinder, and the inlet pipe and outlet pipe are respectively installed at both ends of the circulation pipe.

[0008] Preferably, multiple heat-conducting plates are welded to the outer side of the inner cylinder, and the circulation pipe passes through the heat-conducting plates.

[0009] Preferably, the external cooling mechanism consists of a cooling chamber, an inlet pipe, and an outlet pipe. The cooling chamber is installed on the outside of the material cylinder, and the inlet pipe and outlet pipe are installed at the upper and lower ends of the cooling chamber.

[0010] Preferably, the turning mechanism consists of a power mechanism, a shaft, a first spiral blade, and a second spiral blade. The shaft is rotatably installed inside the material cylinder and passes through the inner cylinder. The first spiral blade is welded to the outside of the shaft at the inner section of the inner cylinder, and the second spiral blade is welded to the outside of the shaft at the inner end of the discharge pipe. The upper end of the shaft passes through the material cylinder and is installed at the bottom end of the power mechanism, and the bottom end of the power mechanism is installed at the upper end of the material cylinder.

[0011] Preferably, the power mechanism consists of an electric motor and a gearbox, with the gearbox mounted at the upper end of the material cylinder and the electric motor mounted on the upper side of the gearbox.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The turning mechanism is started by switching on the switch. The turning mechanism starts to work and drives the material to circulate and turn inside the inner cylinder and the material cylinder. During the continuous turning of the material, the internal cooling mechanism and the external cooling mechanism continuously and rapidly cool the material. The advantage of this device is that it can not only store the material while cooling it, but also avoid the problem of water vapor in the air condensing due to the temperature drop when the material is cooled, which would increase the humidity of the material.

[0014] 2. When cooling is required, the cryogenic liquid flows into the circulation pipe from the inlet pipe. Since the circulation pipe is close to the material inside the inner cylinder and the material cylinder, the cryogenic liquid in the circulation pipe will exchange heat with the material and absorb the heat of the material, thereby cooling the material. After absorbing the heat, the heated liquid will be discharged from the circulation pipe through the outlet pipe so that it can be recycled after being cooled again.

[0015] 3. During the cooling operation, the cryogenic liquid is introduced into the cooling chamber through the inlet pipe. The cryogenic liquid in the cooling chamber comes into contact with the barrel wall. Since the material inside the barrel is a heat source, heat will be transferred from the material through the barrel wall to the cryogenic liquid in the cooling chamber, thereby cooling the material inside the inner barrel. As heat is continuously absorbed, the temperature of the cryogenic liquid gradually rises. The heated liquid is then discharged from the cooling chamber through the outlet pipe and can be cooled and recycled again.

[0016] 4. When it is necessary to turn the material over, the power mechanism is activated by the switch. The power mechanism drives the shaft to rotate in the forward direction. The rotation of the shaft will drive the first and second spiral blades to rotate together. The rotation direction of the first and second spiral blades matches the lifting direction of the material, thereby lifting the material upward. The first spiral blade is mainly responsible for moving the material at the bottom of the inner cylinder upward along the inner cylinder, so that the material forms a circulation and turning inside the inner cylinder and the material cylinder. This allows the material to contact the internal and external cooling mechanisms more evenly, improving the cooling effect. When it is necessary to discharge the material, the power mechanism drives the shaft to rotate in the reverse direction. At this time, the rotation direction of the second spiral blade will push the material towards the discharge pipe, thus facilitating the smooth discharge of the material from the discharge pipe.

[0023] 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.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the present invention, an automatic control cooling machine includes a cooling device 1. The cooling device 1 consists of a material cylinder 4 and an inner cylinder 14. The inner cylinder 14 is welded inside the material cylinder 4. A turning mechanism 19 is installed inside the material cylinder 4 at the inner section of the inner cylinder 14. An external cooling mechanism 2 is installed on the outside of the material cylinder 4. An internal cooling mechanism 15 is installed on the outside of the inner cylinder 14. A cover 5 is rotatably installed at the upper inlet of the material cylinder 4. A conical cover 11 is installed at the bottom of the material cylinder 4. A discharge pipe is installed at the bottom of the conical cover 11. A cover 5 is installed on the upper side of the discharge pipe. There is a control valve 13, a support leg 22 is installed at the bottom of the material cylinder 4, and multiple heat-conducting plates 21 are welded to the outside of the inner cylinder 14. The circulation pipe 20 passes through the heat-conducting plates 21. The heat-conducting plates 21 have good thermal conductivity. Their presence greatly increases the contact area between the low-temperature liquid inside the circulation pipe 20 and the heat source, i.e., the material. When the low-temperature liquid flows in the circulation pipe 20, heat can be transferred from the material to the low-temperature liquid inside the circulation pipe 20 more quickly and efficiently. In this way, the efficiency of heat exchange is effectively improved, thereby enhancing the cooling effect on the material.

[0025] The internal cooling mechanism 15 consists of a circulation pipe 20, an inlet pipe 10, and an outlet pipe 9. The circulation pipe 20 is wound around the outside of the inner cylinder 14. The inlet pipe 10 and the outlet pipe 9 are respectively installed at both ends of the circulation pipe 20. When cooling is required, the low-temperature liquid flows into the circulation pipe 20 from the inlet pipe 10. Since the circulation pipe 20 is close to the material inside the inner cylinder 14 and the material cylinder 4, the low-temperature liquid in the circulation pipe 20 will exchange heat with the material, absorbing the heat of the material, thereby cooling the material. After absorbing the heat, the liquid with the increased temperature will be discharged from the circulation pipe 20 through the outlet pipe 9 for subsequent cooling and recycling.

[0026] The external cooling mechanism 2 consists of a cooling chamber 3, an inlet pipe 10, and an outlet pipe 9. The cooling chamber 3 is installed on the outside of the material cylinder 4, and the inlet pipe 10 and the outlet pipe 9 are installed at the upper and lower ends of the cooling chamber 3. During the cooling operation, the low-temperature liquid is introduced into the cooling chamber 3 through the inlet pipe 10. The low-temperature liquid in the cooling chamber 3 comes into contact with the wall of the material cylinder 4. Since the material inside the material cylinder 4 is a heat source, heat will be transferred from the material through the wall of the material cylinder 4 to the low-temperature liquid in the cooling chamber 3, thereby cooling the material inside the inner cylinder 14. As heat is continuously absorbed, the temperature of the low-temperature liquid gradually rises. The heated liquid is then discharged from the cooling chamber 3 through the outlet pipe 9 and can be cooled and recycled again.

[0027] The turning mechanism 19 consists of a power mechanism 6, a shaft 18, a first spiral blade 16, and a second spiral blade 17. The shaft 18 is rotatably mounted inside the material cylinder 4 and passes through the inner cylinder 14. The first spiral blade 16 is welded to the outside of the shaft 18 at the inner section of the inner cylinder 14, and the second spiral blade 17 is welded to the outside of the shaft 18 at the inner end of the discharge pipe. The upper end of the shaft 18 passes through the material cylinder 4 and is mounted at the bottom of the power mechanism 6, while the bottom of the power mechanism 6 is mounted at the upper end of the material cylinder 4. When it is necessary to turn the material, the power mechanism 6 is activated by a switch. The power mechanism 6 drives the shaft 18 to rotate forward, and the rotation of the shaft 18 drives the first spiral blade 17. The first spiral blade 16 and the second spiral blade 17 rotate together. The rotation direction of the first spiral blade 16 and the second spiral blade 17 matches the lifting direction of the material, thereby lifting the material upward. The first spiral blade 16 is mainly responsible for moving the material at the bottom of the inner cylinder 14 upward along the inner cylinder 14, so that the material forms a circulation and tumbling inside the inner cylinder 14 and the material cylinder 4. This allows the material to contact the internal and external cooling mechanisms 15 and 2 more evenly, improving the cooling effect. When it is necessary to discharge the material, the power mechanism 6 drives the shaft 18 to rotate in the opposite direction. At this time, the rotation direction of the second spiral blade 17 will push the material towards the discharge pipe, so that the material can be discharged smoothly from the discharge pipe.

[0028] The power mechanism 6 consists of an electric motor 7 and a gearbox 8. The gearbox 8 is installed at the upper end of the material cylinder 4, and the electric motor 7 is installed on the upper side of the gearbox 8. In use, the electric motor 7 is turned on by a switch, and the electric motor 7 starts to run and output power. Since the initial speed output by the electric motor 7 may not meet the actual working requirements of the flipping mechanism 19, the running speed of the electric motor 7 needs to be adjusted by the gearbox 8. The gearbox 8 will reasonably reduce or increase the speed of the electric motor 7 according to the actual set parameters, and then output the adjusted power to the shaft 18, thereby driving the flipping mechanism 19 to work at a suitable speed.

[0029] The working principle and usage process of this utility model are as follows: In actual use, the cover 5 is first rotated open, and the material is introduced into the material cylinder 4 through the feed port. When it is necessary to cool the material, the low-temperature liquid is introduced into the internal cooling mechanism 15 and the external cooling mechanism 2 respectively. Then, the turning mechanism 19 is started by switching on the switch. The turning mechanism 19 starts to work and drives the material to circulate and turn inside the inner cylinder 14 and the material cylinder 4. During the continuous turning of the material, the internal cooling mechanism 15 and the external cooling mechanism 2 continuously and rapidly cool the material. The advantage of this device is that it can not only store the material while cooling it, but also avoid the problem of water vapor in the air condensing due to the temperature drop when the material is cooled, thus increasing the humidity of the material.

[0030] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
