Description

Technical Field

[0001] The utility model relates to the technical field of polyolefin wax slurry production, in particular to a reaction kettle heating system for polyolefin wax slurry production. Background Technique

[0002] The production process of polyolefin wax slurry is as follows:

[0003] 1. Add the formulated raw materials into the emulsifying kettle at one time, start stirring, control the rotation speed at 300 - 500 revolutions, and start heating.

[0004] 2. Adjust the material temperature to 140 - 150 °C, adjust the rotation speed to 800 - 1000 revolutions / min, and the emulsifying time is 45 - 50 minutes.

[0005] 3. Pass cooling water to cool down. When the material temperature reaches below 50 °C, turn off the stirring.

[0006] 4. Discharge the material and fill it into the warehouse.

[0007] Since it is necessary to heat and cool the emulsifying kettle, in the prior art, heating and cooling are carried out by winding two coiled pipes on the surface of the emulsifying kettle. One coiled pipe is responsible for passing the heat medium for heating, and the other coiled pipe is responsible for passing the refrigerant for cooling. In this heating and cooling method, since the refrigerant and the heat medium need to share the surface area of the emulsifying kettle, when heating and cooling, neither the heat medium nor the refrigerant can exchange heat with the material to the maximum extent, resulting in low heat exchange efficiency. Content of the Utility Model

[0008] In order to solve the problems mentioned in the above background technique, the utility model provides a reaction kettle heating system for polyolefin wax slurry production.

[0009] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0010] A reaction kettle heating system for polyolefin wax slurry production includes an emulsifying kettle, a first arc-shaped heat exchanger, a second arc-shaped heat exchanger, and a horizontal drive box. There are two of each of the first arc-shaped heat exchanger and the second arc-shaped heat exchanger, and the first arc-shaped heat exchanger and the second arc-shaped heat exchanger surround the emulsifying kettle. The first arc-shaped heat exchanger and the second arc-shaped heat exchanger face each other. There are four horizontal drive boxes, and the four horizontal drive boxes respectively drive two first arc-shaped heat exchangers and two second arc-shaped heat exchangers to move horizontally. Two first connection sockets are provided on the side of the first arc-shaped heat exchanger close to the side where the second arc-shaped heat exchanger is close to it. Two second connection sockets are provided on the side of the second arc-shaped heat exchanger close to the first arc-shaped heat exchanger. The first connection socket and the second connection socket correspond and match with each other and can be plugged and connected.

[0011] Preferably, a first electric valve is installed on the first connecting insertion tube, and a second electric valve is installed on the second connecting insertion tube.

[0012] Preferably, a medium inlet pipe and a medium outlet pipe are respectively provided on one side of the first arc-shaped heat exchanger away from the second arc-shaped heat exchanger.

[0013] Preferably, a horizontally arranged threaded rod is rotatably installed inside the horizontal drive box. A slide rail is provided on the bottom inner wall of the horizontal drive box. A threaded sleeve is slidably installed on the slide rail. The threaded sleeve is threadedly installed outside the threaded rod. The top of the threaded sleeve is fixed with a connecting rod. The top of the connecting rod extends to the outside of the horizontal drive box through a reserved strip-shaped notch and is fixed to one of the first arc-shaped heat exchanger and the second arc-shaped heat exchanger.

[0014] Preferably, one end of the threaded rod extends to the outside of the horizontal drive box and is fixed with a disc. A holding handle is fixed on the side of the disc away from the horizontal drive box.

[0015] Preferably, a horizontally arranged positioning pin is movably installed on the disc through a through hole. A positioning sleeve is fixed on the side of the horizontal drive box close to the disc. The positioning pin and the positioning sleeve are correspondingly matched.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. The horizontal drive box can drive the first arc-shaped heat exchanger and the second arc-shaped heat exchanger to move horizontally away from and close to the emulsifying kettle, so that the emulsifying kettle can be heated and cooled by adjusting the positions of the first arc-shaped heat exchanger and the second arc-shaped heat exchanger. Compared with the traditional method of heat exchange between different coils or interlayers of hot and cold media and materials, in this solution, the first arc-shaped heat exchanger and the second arc-shaped heat exchanger can maintain a larger contact area with the emulsifying kettle, thus effectively improving the heating and cooling efficiency, and the hot and cold media are separated and no heat exchange will occur between them, which is more energy-saving and environmentally friendly.

[0018] 2. Holding the holding handle can conveniently and labor-savingly drive the threaded rod to rotate, drive the threaded sleeve to move horizontally, and then drive the connecting rod to move horizontally, so as to drive the first arc-shaped heat exchanger and the second arc-shaped heat exchanger to move horizontally.

[0019] 3. Through the cooperation of the positioning pin and the positioning sleeve, it is ensured that the positions of the first arc-shaped heat exchanger and the second arc-shaped heat exchanger can be locked after approaching the emulsifying kettle, so as to ensure the tightness during the heating and cooling process and thus ensure the heat exchange effect.

[0030] Embodiment 1

[0031] Reference Figures 1-7 , a reactor heating system for producing polyolefin wax slurry, including an emulsifying kettle 1, a first arc-shaped heat exchanger 2, a second arc-shaped heat exchanger 3, and a horizontal drive box 4. There are two of each of the first arc-shaped heat exchanger 2 and the second arc-shaped heat exchanger 3, and the first arc-shaped heat exchanger 2 and the second arc-shaped heat exchanger 3 surround the emulsifying kettle 1. The first arc-shaped heat exchanger 2 and the second arc-shaped heat exchanger 3 face each other. There are four horizontal drive boxes 4, and the four horizontal drive boxes 4 respectively drive the two first arc-shaped heat exchangers 2 and the two second arc-shaped heat exchangers 3 to move horizontally. On the side where the first arc-shaped heat exchanger 2 is close to the second arc-shaped heat exchanger 3 and they approach each other, there are two first connection sockets 203. On the side of the second arc-shaped heat exchanger 3 close to the first arc-shaped heat exchanger 2, there are two second connection sockets 301. The first connection socket 203 and the second connection socket 301 correspond and match with each other and can be inserted and connected;

[0032] Through the horizontal drive box 4, the first arc-shaped heat exchanger 2 and the second arc-shaped heat exchanger 3 can be driven to move horizontally away from and close to the emulsifying kettle 1. A pair of the first arc-shaped heat exchanger 2 and the second arc-shaped heat exchanger 3 form a group. The two groups of the first arc-shaped heat exchanger 2 and the second arc-shaped heat exchanger 3 are respectively passed with cold medium and hot medium. Thus, the emulsifying kettle 1 can be heated and cooled by adjusting the positions of the first arc-shaped heat exchanger 2 and the second arc-shaped heat exchanger 3. Compared with the traditional method of heat exchange between cold and hot media and materials through different coils or interlayers, in this solution, the first arc-shaped heat exchanger 2 and the second arc-shaped heat exchanger 3 can maintain a larger contact area with the emulsifying kettle 1, thereby effectively improving the heating and cooling efficiency. Moreover, the cold and hot media are separated and no heat exchange occurs between them, which is more energy-saving and environmentally friendly.

[0033] Among them, a first electric valve 204 is installed on the first connection socket 203, and a second electric valve 302 is installed on the second connection socket 301. When the first connection socket 203 and the second connection socket 301 are inserted, the first arc-shaped heat exchanger 2 and the second arc-shaped heat exchanger 3 are interconnected.

[0034] Among them, on the side of the first arc-shaped heat exchanger 2 away from the second arc-shaped heat exchanger 3, there are respectively a medium inlet pipe 201 and a medium outlet pipe 202. The cold and hot media enter the first arc-shaped heat exchanger 2 through the medium inlet pipe 201, then flow into the second arc-shaped heat exchanger 3 through the first connection socket 203 and the second connection socket 301 and then flow back to the first arc-shaped heat exchanger 2, and finally flow out from the medium outlet pipe 202, thus completing heating and cooling.

[0035] Among them, a horizontally arranged threaded rod 401 is rotatably installed inside the horizontal drive box 4. A slide rail 402 is provided on the bottom inner wall of the horizontal drive box 4. A threaded sleeve 403 is slidably installed on the slide rail 402. The threaded sleeve 403 is threadedly installed outside the threaded rod 401. The top of the threaded sleeve 403 is fixed with a connecting rod 404. The top of the connecting rod 404 extends to the outside of the horizontal drive box 4 through a reserved strip-shaped notch and is fixed to one of the first arc-shaped heat exchanger 2 and the second arc-shaped heat exchanger 3.

[0036] When the threaded rod 401 rotates, it can drive the threaded sleeve 403 to move horizontally, and then drive the connecting rod 404 to move horizontally, so as to drive the first arc-shaped heat exchanger 2 and the second arc-shaped heat exchanger 3 to move horizontally.

[0037] Among them, one end of the threaded rod 401 extends to the outside of the horizontal drive box 4 and is fixed with a disc 405. A holding handle 406 is fixed on the side of the disc 405 away from the horizontal drive box 4. Holding the holding handle 406 can conveniently and labor-savingly drive the first arc-shaped heat exchanger 2 and the second arc-shaped heat exchanger 3 to move horizontally.

[0038] Among them, a horizontally arranged positioning pin 407 is movably installed on the disc 405 through a through hole. A pull ring 408 is fixed on the positioning pin 407. A positioning sleeve 409 is fixed on the side of the horizontal drive box 4 close to the disc 405. The positioning pin 407 and the positioning sleeve 409 are correspondingly matched.

[0039] Through the cooperation of the positioning pin 407 and the positioning sleeve 409, it is ensured that the positions of the first arc-shaped heat exchanger 2 and the second arc-shaped heat exchanger 3 can be locked after approaching the emulsifying kettle 1, so as to ensure the joint tightness during the heating and cooling processes, and thus ensure the heat exchange effect.
