Description

Technical Field

[0001] The present invention relates to the technical field of rubber antioxidant granulation processing, and particularly to a rubber antioxidant granulation device with a heat exchange structure and a granulation method. Background Art

[0002] Due to the high melting point characteristics of rubber antioxidants, the temperature needs to be controlled during the granulation process to ensure fluidity. When the material is initially put in, the temperature of the material needs to be quickly raised to the flowing state to avoid local condensation and caking caused by slow heating. However, it is found that most of them cannot perform quick heat exchange treatment on the rubber antioxidant granulation material of the heat exchange structure when the material is initially put in, which will affect the subsequent feeding into the rubber antioxidant granulator. The clogging of the cutter holes in the rubber antioxidant granulator is caused by insufficient fluidity or condensation and caking of the rubber antioxidant granulation material. For example, the prior art application number CN221132139U provides a rubber antioxidant DTPD granulation device that can save space. It includes a sealed rectangular shell, a hemispherical cooling tank connected to the bottom inside the rectangular shell, and a distributor arranged at the top inside the shell. A jet stirring structure is arranged in the cooling tank, a gas and water mist spraying structure is arranged at the top inside the rectangular shell, a cooling water heat exchange structure is arranged in the middle of the rectangular shell, and a discharge pipe is connected to the bottom end of the cooling tank. The present invention has the effect of improving the sealing performance and space utilization rate of the device. It is known from the actual use of the above prior art that it mainly conducts heat exchange through the cooling water heat exchange structure and improves the sealing performance and space utilization rate of the device. However, it is found in use that it cannot perform quick heat exchange treatment on the rubber antioxidant granulation material of the heat exchange structure when the material is initially put in. When the material is initially put in, the temperature of the material needs to be quickly raised to the flowing state to avoid local condensation and caking caused by slow heating, which will affect the subsequent feeding into the rubber antioxidant granulator. The clogging of the cutter holes in the rubber antioxidant granulator is caused by insufficient fluidity or condensation and caking of the rubber antioxidant granulation material. Therefore, according to the actual use situation, the above prior art is improved. Summary of the Invention

A support plate is arranged on one side wall of the inner cavity of the installation shell. A motor is arranged at intervals on one side wall of the inner cavity of the installation shell.

A second bevel gear that matches is meshed on one side of the bottom of the first bevel gear. A connecting round pipe is embedded in the middle position side wall of the second bevel gear. Both ends of the connecting round pipe are rotatably connected and extend to the outer side wall of the top of the installation shell and the bottom side wall at intervals of the inner cavity of the installation shell. And a rotary joint is arranged at one end of the top of the connecting round pipe. And an outer round pipe is embedded on the outer side wall of one end of the bottom of the connecting round pipe. Both ends of the outer round pipe are rotatably connected and extend to the top and bottom outer side walls of the inner cavity of the feeding kettle hopper. Three groups of square stirring blocks with the same structure are arranged in an up-and-down array on the outer side wall of one end of the outer round pipe adjacent to the inner cavity of the feeding kettle hopper.

[0007] Further: The connecting round pipe includes a T-shaped connecting liquid pipe arranged at one end of the inner wall of the bottom adjacent to the outer round pipe. A three-way solenoid valve is installed at one end of the top of the T-shaped connecting liquid pipe. And the side wall of one end of the bottom of the T-shaped connecting liquid pipe is connected with a cooling water pipe. And the side wall of the other end of one end of the bottom of the T-shaped connecting liquid pipe is connected with a heat-conducting oil pipe. Both ends of the bottom of the cooling water pipe and the heat-conducting oil pipe are symmetrically connected with two groups of spiral temperature-guiding heat exchange pipes with the same structure. The other ends of the two groups of spiral temperature-guiding heat exchange pipes are symmetrically connected with two groups of connecting liquid pipes with the same structure at the bottom. One end of each of the two groups of connecting liquid pipes is connected with two groups of circulation liquid pipes with the same structure. Four groups of spiral temperature-guiding heat exchange pipes and four groups of connecting liquid pipes with the same structure are connected in an up-and-down array at one end of the bottom of each of the two groups of circulation liquid pipes. The six groups of spiral temperature-guiding heat exchange pipes and connecting liquid pipes are arranged in the inner cavity of the square stirring block.

[0008] Further: The square stirring block includes scraping plates arranged on the side walls of one end.

[0009] Further: The feeding kettle hopper includes a temperature sensor embedded on one side wall of the inner cavity. And a recovery slideway is arranged on the outer side wall of the bottom of the feeding kettle hopper. A recovery box is arranged on one side wall of the recovery slideway.

[0010] Further: The square stirring block includes copper heat-conducting coatings provided on all outer side walls.

[0011] A granulation method for a rubber antioxidant granulating device with a heat exchange structure includes the following steps: S1: When starting work, the operator puts the rubber antioxidant granulating material into the inner cavity of the charging kettle hopper through the feeding pipe on the top of the charging kettle hopper, and connects to the external heat-conducting oil conveying pipe or cooling water conveying pipe through the rotary joint provided at one end of the top of the connecting round pipe; S2: Connect to the heat-conducting oil conveying pipe for heating operation. The heat-conducting oil enters the connecting round pipe, and then enters the T-shaped connecting liquid pipe. The plc controller transmits an electrical signal and triggers the three-way solenoid valve to connect the heat-conducting oil pipe connected to the other side wall at one end of the bottom, and blocks the cooling water pipe connected to the side wall at one end of the bottom of the T-shaped connecting liquid pipe, so that the heat-conducting oil enters the inner cavity of a group of spiral heat-conducting and heat-exchanging pipes through the heat-conducting oil pipe; S3: When the heat-conducting oil pipe in the inner cavity of the spiral heat-conducting and heat-exchanging pipe is full, the heat-conducting oil then passes through a group of connecting liquid pipes and the circulating liquid pipe, then operates through the spiral heat-conducting and heat-exchanging pipes and connecting liquid pipes on the same side, and then returns to the bottom group of circulating liquid pipes; S4: The plc controller transmits an electrical signal and triggers the motor execution end to drive the first bevel gear to rotate. The rotation of the first bevel gear drives the rotation of the connecting round pipe embedded in the side wall at the middle position of the second bevel gear. When the rotary joint is connected to the external heat-conducting oil conveying pipe or cooling water conveying pipe, it can continue to stably convey the heat-conducting oil medium or cooling water medium while the connecting round pipe drives the rotation; S: The rotation of the connecting round pipe drives the rotation of the outer round pipe, and the three square stirring blocks rotate to turbulently stir the rubber antioxidant granulating material in the inner cavity of the charging kettle hopper. Since the six groups of spiral heat-conducting and heat-exchanging pipes and connecting liquid pipes are all arranged in the inner cavity of the square stirring block, it also accelerates the uniform conduction of the temperature of the rubber antioxidant granulating material. The scraper avoids the adhesion of the material on the inner wall of the charging kettle hopper and scrapes it off in time. At the same time, the temperature sensor is convenient for observing the temperature of the rubber antioxidant granulating material in the inner cavity of the charging kettle hopper, and judges whether to perform heating operation and cooling operation according to the above operations, so as to realize the granulation work through the use of the heat exchange component.

[0012] Compared with the prior art, the beneficial effects of the present invention are: The present invention facilitates the quick heat exchange treatment of the rubber antioxidant granulating material of the heat exchange structure when the material is initially put in through the quick heat exchange component, can quickly raise the temperature of the material to the flowing state, and avoids local condensation and caking due to slow heating, which affects the subsequent feeding into the rubber antioxidant granulating machine. Due to the insufficient fluidity or condensation and caking of the rubber antioxidant granulating material, the cutter holes in the rubber antioxidant granulating machine are blocked, thereby improving the granulation efficiency of the rubber antioxidant.

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution: a rubber antioxidant granulating device with a heat exchange structure, including a footrest 1, a feeding kettle hopper 2, a rubber antioxidant granulating machine body 3, a feeding pipe 4, a feed pipe 5, and a quick heat exchange assembly 6; On the outer side wall of the top of the footrest 1, there is a feeding kettle hopper 2. On the bottom side wall of the feeding kettle hopper 2, two groups of the same-structured feeding pipes 4 are symmetrically embedded. At one end of the bottom of the two groups of feeding pipes 4, there is a rubber antioxidant granulating machine body 3. Both side walls of the rubber antioxidant granulating machine body 3 are arranged on the bottom side wall of the footrest 1, and on one side wall of the top of the feeding kettle hopper 2, there is a feed pipe 5 embedded. The quick heat exchange assembly 6 is arranged at the middle position adjacent to the feed pipe 5 on the top side wall of the feeding kettle hopper 2. Through the quick heat exchange assembly 6, it is convenient to quickly heat-exchange the rubber antioxidant granulating material of the heat exchange structure when the material is initially put in, and can quickly raise the material temperature to the flowing state, avoiding local condensation and caking caused by too slow heating, which affects the subsequent feeding into the rubber antioxidant granulating machine. Due to insufficient fluidity or condensation and caking of the rubber antioxidant granulating material, the cutter holes in the rubber antioxidant granulating machine are blocked, thereby improving the rubber antioxidant granulating efficiency.

[0023] Among them, preferably, the quick heat exchange component 6 includes an installation shell 61 arranged at the middle position of the top side wall of the feeding kettle hopper 2 adjacent to the middle of the feeding pipe 5. On one side wall of the inner cavity of the installation shell 61, there is a support plate 63, and on the spaced side wall of one side of the inner cavity of the installation shell 61, there is a motor 62. One end of the execution end of the motor 62 is rotatably connected to the side wall of the support plate 63. And at one end of the execution end of the motor 62, there is a first bevel gear 64. On the bottom side of the first bevel gear 64, there is a meshing second bevel gear 65 that matches it. In the middle position of the side wall of the second bevel gear 65, there is an embedded connecting round pipe 66. Both ends of the connecting round pipe 66 are rotatably connected and extend to the outer side wall of the top of the installation shell 61 and the spaced side wall of the bottom of the inner cavity of the installation shell 61. And at one end of the top of the connecting round pipe 66, there is a rotary joint 67. And on the outer side wall of one end of the bottom of the connecting round pipe 66, there is an embedded outer round pipe 68. Both ends of the outer round pipe 68 are rotatably connected and extend to the outer side walls of the top and bottom of the inner cavity of the feeding kettle hopper 2. On the outer side wall of one end of the outer round pipe 68 adjacent to the inner cavity of the feeding kettle hopper 2, there are three groups of square stirring blocks 69 with the same structure arranged in an up-and-down array. The PLC controller transmits an electric signal and triggers the execution end of the motor 62 to drive the first bevel gear 64 arranged at one end to rotate while being supported by the side wall of the support plate 63 through the rotation of one end of the execution end of the motor 62. The rotation of the first bevel gear 64 drives the second bevel gear 65 that meshes with the bottom side of it. In the middle position of the side wall of the second bevel gear 65, there is an embedded connecting round pipe 66 that rotates while being supported by both ends of the connecting round pipe 66 extending to the outer side wall of the top of the installation shell 61 and the spaced side wall of the bottom of the inner cavity of the installation shell 61. When the rotary joint 67 at one end of the top of the connecting round pipe 66 is connected to an external heat transfer oil delivery pipe or a cooling water delivery pipe, it can still stably transport the heat transfer oil medium or the cooling water medium while the connecting round pipe 66 rotates. And the rotation of the connecting round pipe 66 drives the outer round pipe 68 embedded in the outer side wall of one end of the bottom to rotate while being supported by both ends of the outer round pipe 68 extending to the outer side walls of the top and bottom of the inner cavity of the feeding kettle hopper 2, driving the three groups of square stirring blocks 69 with the same structure arranged in an up-and-down array on the outer side wall of one end of the outer round pipe 68 adjacent to the inner cavity of the feeding kettle hopper 2 to rotate and agitate the rubber antioxidant granulation material in the inner cavity of the feeding kettle hopper 2 by disturbing the flow.

[0024] Preferably, the connecting circular pipe 66 includes a T-shaped connecting liquid pipe 661 disposed at one end of the bottom of the inner wall of the outer circular pipe 68 adjacent thereto. At the top end of the T-shaped connecting liquid pipe 661, a three-way solenoid valve 662 is installed. And at one side wall of the bottom end of the T-shaped connecting liquid pipe 661, a cooling water pipe 663 is connected. And at the other side wall of the bottom end of the T-shaped connecting liquid pipe 661, a heat-conducting oil pipe 664 is connected. At the bottom end of both the cooling water pipe 663 and the heat-conducting oil pipe 664, two groups of spiral temperature-guiding heat exchange pipes 665 with the same structure are symmetrically connected. At the bottom of the other ends of the two groups of spiral temperature-guiding heat exchange pipes 665, two groups of connecting liquid pipes 666 with the same structure are symmetrically connected. One end of each of the two groups of connecting liquid pipes 666 is connected to two groups of circulating liquid pipes 667 with the same structure. At the bottom end of each of the two groups of circulating liquid pipes 667, four groups of spiral temperature-guiding heat exchange pipes 665 and four groups of connecting liquid pipes 666 with the same structure are vertically and arrayedly connected. The six groups of spiral temperature-guiding heat exchange pipes 665 and the connecting liquid pipes 666 are all disposed in the inner cavity of the square stirring block 69. And at the bottom end of each of the two groups of circulating liquid pipes 667, two solenoid valves 668 with the same structure are installed. The operator inputs the rubber antioxidant granulation material into the inner cavity of the feeding kettle 2 through a feeding pipe 5 embedded in one side wall of the top of the feeding kettle 2. Through a rotary joint 67 provided at the top end of the connecting circular pipe 66, an external heat-conducting oil delivery pipe or a cooling water delivery pipe needs to be connected. When connecting the heat-conducting oil delivery pipe for heating operation, the heat-conducting oil enters the connecting circular pipe 66 and then enters the T-shaped connecting liquid pipe 661 disposed at one end of the bottom of the inner wall of the outer circular pipe 68 adjacent to the connecting circular pipe 66. The PLC controller transmits an electrical signal and triggers the three-way solenoid valve 662 (a prior art device) installed at the top end of the T-shaped connecting liquid pipe 661 to communicate with the heat-conducting oil pipe 664 connected to the other side wall of the bottom end, and block the cooling water pipe 663 connected to the side wall of the bottom end of the T-shaped connecting liquid pipe 661, so that the heat-conducting oil enters the inner cavity of a group of spiral temperature-guiding heat exchange pipes 665 through the heat-conducting oil pipe 664. When the heat-conducting oil pipe 664 in the inner cavity of the spiral temperature-guiding heat exchange pipe 665 is full, the heat-conducting oil then enters a group of connecting liquid pipes 666 with the same structure symmetrically connected to the bottom of the other end of a group of spiral temperature-guiding heat exchange pipes 665. The heat-conducting oil then enters a group of circulating liquid pipes 667 with the same structure connected to one end of each of a group of connecting liquid pipes 666, and then flows through and reaches two groups of spiral temperature-guiding heat exchange pipes 665 and two groups of connecting liquid pipes 666 with the same structure vertically and arrayedly connected to the bottom end of the same side of a group of circulating liquid pipes 667 on the same side, and then returns to the bottom group of circulating liquid pipes 667. And at the bottom end of each of a group of circulating liquid pipes 667, a solenoid valve 668 is installed. When the heat-conducting oil needs to be replaced, the PLC controller transmits an electrical signal and triggers the solenoid valve 668 to open and flow out to the interval side of the recovery chute 22 provided on the outer side wall of the bottom of the feeding kettle 2, and enters the interval side of the recovery box 23 provided on one side wall of the recovery chute 22 for storage, waiting for subsequent use, and through the same above operations.

[0025] Preferably, the square stirring block 69 has scraping plates 691 provided on the side walls at one end. By having the scraping plates 691 provided on the side walls at one end of the square stirring block 69, it is possible to prevent materials from adhering to the inner wall of the charging kettle hopper 2 and scrape them off in a timely manner.

[0026] Preferably, the charging kettle hopper 2 includes a temperature sensor 21 embedded in the side wall on one side of the inner cavity, and a recovery chute 22 is provided on the outer side wall at the bottom of the charging kettle hopper 2.

By having the temperature sensor 21 embedded in the side wall on one side of the inner cavity of the charging kettle hopper 2, it is convenient to observe the temperature of the rubber antioxidant granulation materials in the inner cavity of the charging kettle hopper 2, and determine whether to perform a temperature increase operation or a temperature decrease operation according to the above operations. When the temperature is too high, cooling water can be introduced for a temperature decrease operation. The PLC controller transmits an electrical signal and triggers a three-way solenoid valve 662 of the prior art installed at the top end of the T-shaped connecting liquid pipe 661 to communicate with the cooling water pipe 663 connected to the side wall at the bottom end, block the heat transfer oil pipe 664 connected to the other side wall at the bottom end of the T-shaped connecting liquid pipe 661, and perform the same operation as above, so that the cooling water enters the other group of flow liquid pipes 667. At the bottom end of each of the three spiral temperature guiding and heat exchange pipes 665 and three connecting liquid pipes 666 with the same structure are arranged in an up-and-down array, and then through the same operation as above, it is discharged through the solenoid valves 668 provided to be stored in the other side of the recovery box 23 at intervals for subsequent use.

[0027] Preferably, the square stirring block 69 has copper-based temperature guiding coatings 692 provided on the outer side walls. By having the copper-based temperature guiding coatings 692 provided on the outer side walls of the square stirring block 69, it is convenient to accelerate the conduction of temperature.

[0028] It should be noted that when the temperature is too high, cooling water can be introduced for a temperature decrease operation. The PLC controller transmits an electrical signal and triggers a three-way solenoid valve 662 of the prior art installed at the top end of the T-shaped connecting liquid pipe 661 to communicate with the cooling water pipe 663 connected to the side wall at the bottom end, block the heat transfer oil pipe 664 connected to the other side wall at the bottom end of the T-shaped connecting liquid pipe 661, and perform the same operation as above, so that the cooling water enters the other group of flow liquid pipes 667.

[0029] A granulation method of a rubber antioxidant granulation device with a heat exchange structure, characterized by comprising the following steps: S1: At the beginning of the work, the operator puts the rubber antioxidant granulation material into the inner cavity of the charging kettle 2 through the feed pipe 5 on the top of the charging kettle 2, and connects to the external heat transfer oil delivery pipe or the cooling water delivery pipe through the rotary joint 67 arranged at one end of the top of the connecting round pipe 66; S2: Connect to the heat transfer oil delivery pipe for heating operation. The heat transfer oil enters the connecting round pipe 66, and then enters the T-shaped connecting liquid pipe 661. The plc controller transmits an electrical signal and triggers the three-way solenoid valve 662 to connect to the heat transfer oil pipeline 664 connected to the other side wall at one end of the bottom, and blocks the cooling water pipeline 663 connected to the side wall at one end of the bottom of the T-shaped connecting liquid pipe 661, so that the heat transfer oil enters the inner cavity of a group of spiral temperature-conducting heat exchange pipes 665 through the heat transfer oil pipeline 664; S3: When the heat transfer oil pipeline 664 in the inner cavity of the spiral temperature-conducting heat exchange pipe 665 is full, the heat transfer oil then passes through a group of connecting liquid pipes 666 and the circulation liquid pipe 667, and then operates through the spiral temperature-conducting heat exchange pipes 665 and the connecting liquid pipes 666 on the same side, and then returns to the bottom group of circulation liquid pipes 667; S4: The plc controller transmits an electrical signal and triggers the driving end of the motor 62 to drive the first bevel gear 64 to rotate. The rotation of the first bevel gear 64 drives the middle position side wall of the second bevel gear 65 inlaid with the connecting round pipe 66 to rotate. When the rotary joint 67 is connected to the external heat transfer oil delivery pipe or the cooling water delivery pipe, it can still stably transport the heat transfer oil medium or the cooling water medium when the connecting round pipe 66 drives the rotation; S5: The rotation of the connecting round pipe 66 drives the outer round pipe 68 to rotate, and the three groups of square stirring blocks 69 rotate to turbulently stir the rubber antioxidant granulation material in the inner cavity of the charging kettle 2. Because the six groups of spiral temperature-conducting heat exchange pipes 665 and the connecting liquid pipes 666 are both arranged in the inner cavity of the square stirring blocks 69, it also accelerates the uniform conduction of the temperature of the rubber antioxidant granulation material. The scraper 691 prevents the material from sticking to the inner wall of the charging kettle 2 and scrapes it off in time. At the same time, the temperature sensor 21 is convenient for observing the temperature of the rubber antioxidant granulation material in the inner cavity of the charging kettle 2, and determines whether to perform the heating operation and the cooling operation according to the above operations, so as to realize the granulation work through the use of the heat exchange component.

7. A granulation method of a rubber antioxidant granulation device with a heat exchange structure according to any one of claims 1-6, characterized in that: It includes the following steps: S1: When the work starts, the operator puts the rubber antioxidant granulation material into the inner cavity of the feeding kettle hopper (2) through the feeding pipe (5) on the top of the feeding kettle hopper (2), and connects to an external heat-conducting oil delivery pipe or a cooling water delivery pipe through the rotary joint (67) provided at one end of the top of the connecting circular pipe (66); S2: Connect to the heat-conducting oil delivery pipe for heating operation. The heat-conducting oil enters the connecting circular pipe (66), and then enters the T-shaped connecting liquid pipe (661). The plc controller transmits an electrical signal and triggers the three-way solenoid valve (662) to connect the heat-conducting oil pipe (664) connected to the other side wall at one end of the bottom, and block the cooling water pipe (663) connected to the side wall at one end of the bottom of the T-shaped connecting liquid pipe (661), so that the heat-conducting oil enters the inner cavity of a group of spiral temperature-conducting heat exchange pipes (665) through the heat-conducting oil pipe (664); S3: When the inner cavity of the spiral temperature-conducting heat exchange pipe (665) is filled with the heat-conducting oil pipe (664), the heat-conducting oil then passes through a group of connecting liquid pipes (666) and the circulating liquid pipes (667), and then operates through the spiral temperature-conducting heat exchange pipes (665) and connecting liquid pipes (666) on the same side, and then returns to the bottom group of circulating liquid pipes (667); S4: Transmit an electrical signal through the plc controller and trigger the execution end of the motor (62) to drive the first bevel gear (64) to rotate. The rotation of the first bevel gear (64) drives the rotation of the second bevel gear (65) with a connecting circular tube (66) embedded in the side wall at the middle position. When the rotary joint (67) is connected to an external heat transfer oil delivery pipe or a cooling water delivery pipe, it can continuously and stably transport the heat transfer oil medium or the cooling water medium while being driven by the connecting circular tube (66). S5: The rotation of the connecting circular tube (66) drives the rotation of the outer circular tube (68), and the three square stirring blocks (69) rotate to perform turbulent stirring on the rubber antioxidant granulation material in the inner cavity of the feeding kettle hopper (2). Since the six spiral temperature-conducting heat exchange tubes (665) and the connecting liquid tubes (666) are both arranged in the inner cavity of the square stirring blocks (69), it also accelerates the uniform conduction of the temperature of the rubber antioxidant granulation material. The scraper (691) prevents the material from sticking to the inner wall of the feeding kettle hopper (2) and scrapes it off in a timely manner. At the same time, the temperature sensor (21) facilitates observing the temperature of the rubber antioxidant granulation material in the inner cavity of the feeding kettle hopper (2), and determines whether to perform heating or cooling operations through the above operations, so as to realize the granulation work through the use of the heat exchange component.
