Technical Field

[0001] The invention relates to the technical field of temperature regulating devices for regenerated rubber production, and in particular to a temperature regulating and heat-insulating device for a stator tube of a screw pump used for regenerated rubber production. Background Art

[0002] Recycled rubber is a rubber that has been processed from the vulcanized scraps in the production of rubber products. It has a certain degree of plasticity and can be reused. It is called recycled rubber. According to the different waste rubber used, recycled rubber can be divided into outer tires, inner tubes, rubber shoes, etc.

[0003] When recycled rubber is produced, a screw pump stator tube is often used to transport the rubber raw materials. When transporting the rubber raw materials, it is necessary to ensure that the internal temperature is stable at a certain temperature. However, the existing temperature control heating components cannot ensure that the temperature of each section of the screw pump stator tube is uniform and at a suitable transportation temperature.

[0004] Therefore, it is necessary to provide a temperature control and insulation device which can be segmented to adjust the temperature and heat preservation, and is convenient for adjusting the temperature inside the stator tube of the screw pump. Summary of the invention

[0005] The main purpose of the present invention is to provide a temperature regulating and heat-insulating device for a screw pump stator tube used in the production of recycled rubber, so as to solve the problems existing in the prior art.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A temperature regulating and heat-insulating device for a screw pump stator tube for recycled rubber production comprises a frame, on which a first temperature regulating and heat-insulating component and a second temperature regulating and heat-insulating component are slidably connected, the first temperature regulating and heat-insulating component and the second temperature regulating and heat-insulating component are vertically arranged to each other, the first temperature regulating and heat-insulating component and the second temperature regulating and heat-insulating component cooperate to cover the outer side of the screw pump stator tube, and the first temperature regulating and heat-insulating component and the second temperature regulating and heat-insulating component are both connected to cold and hot fluid partitioning introduction components.

[0008] Furthermore, the frame is provided with a first telescopic device and a second telescopic device, the movable end of the first telescopic device is connected to the first temperature regulating and heat preservation component, and the movable end of the second telescopic device is connected to the second temperature regulating and heat preservation component.

[0009] Furthermore, the first temperature regulating and heat-insulating component includes a first sliding frame, which is slidably connected to the frame, and the first sliding frame is connected to the movable end of the first telescopic device. The first sliding frame is connected to a plurality of telescopic push rods, and each of the telescopic push rods is connected to a side peripheral plate.

[0010] Furthermore, the side peripheral plate includes a heat conduction plate and a heat insulation layer, the heat insulation layer is connected to the side of the heat conduction plate away from the stator tube of the screw pump, and a serpentine duct is arranged inside the heat conduction plate, and the serpentine duct is used to pass cold and hot fluids.

[0011] Furthermore, a heating wire groove is provided on one side of the heat conducting plate close to the stator tube of the screw pump, and a heating wire is connected in the heating wire groove.

[0012] Furthermore, the heat conducting plate is a metal heat conducting plate or a ceramic heat conducting plate.

[0013] Furthermore, the cold and hot fluid partitioning introduction component includes a cold water inlet pipe and a hot water inlet pipe, and the cold water inlet pipe and the hot water inlet pipe are respectively connected to a water distribution pipe, the number of water distribution ports of the water distribution pipe is the same as the number of side peripheral plates, and each water distribution port of the water distribution pipe is respectively connected to a serpentine conduit of a side peripheral plate.

[0014] Furthermore, each water outlet of the water distribution pipe is connected to an electromagnetic valve.

[0015] Furthermore, the structure of the second temperature-control and insulation component is the same as that of the first temperature-control and insulation component, and the length of the side peripheral plates on the second temperature-control and insulation component along the axial direction of the screw pump stator tube is the same as the spacing length between adjacent side peripheral plates on the first temperature-control and insulation component.

[0016] Furthermore, the angle of the side peripheral plate is 180°.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] By setting the first temperature regulating and heat-insulating component and the second temperature regulating and heat-insulating component, the temperature of the stator tube of the screw pump can be controlled in different areas, and the temperature can be adjusted according to the temperature changes in different areas of the stator tube of the screw pump. When the first temperature regulating and heat-insulating component has just completed the heating operation, the temperature of its internal pipeline is relatively high, and the cooling effect can be achieved by directly introducing cold fluid through the second temperature regulating and heat-insulating component. There is no need to wait for the overall cooling of the first temperature regulating and heat-insulating component, and the real-time performance of temperature control is better.

[0019] The first telescopic device can split the first temperature-adjusting and heat-insulating component into two parts, and the second telescopic device can split the second temperature-adjusting and heat-insulating component into two parts. The split structure is convenient for maintenance of the stator tube of the screw pump, and the temperature-adjusting and heat-insulating component can be partially replaced or maintained.

[0027] The frame 1 is provided with a first telescopic device 4 and a second telescopic device, the movable end of the first telescopic device 4 is connected to the first temperature regulating and heat preservation component 2, and the movable end of the second telescopic device is connected to the second temperature regulating and heat preservation component 3. In this embodiment, the first telescopic device 4 and the second telescopic device adopt electric push rods.

[0028] The first temperature control and insulation component 2 includes a first sliding frame 21, which is slidably connected to the frame 1. The first sliding frame 21 is connected to the movable end of the first telescopic device 4. A plurality of telescopic push rods 22 are connected to the first sliding frame 21, and each of the telescopic push rods 22 is connected to a side plate 23. In this embodiment, the angle of the side plate is 180°. A total of two first sliding frames 21 are arranged on the frame 1. The side plates 23 at corresponding positions on the two first sliding frames 21 cooperate to cover the outer periphery of the stator tube of the screw pump. The first temperature control and insulation component 2 can be split into two parts by two first telescopic devices 4, and the second temperature control and insulation component 3 can be split into two parts by two second telescopic devices. The split structure facilitates maintenance of the stator tube 5 of the screw pump, and the temperature control and insulation component can be partially replaced or maintained, without having to replace the entire temperature control and insulation component when it is damaged, thereby saving costs.

[0029] As an optimization, elastic sealing rubber is provided on the peripheral sides of the side peripheral plates 23 to ensure that the connection between the side peripheral plates 23 is more compact and the sealing and heat preservation effect is better.

[0030] The side peripheral plate 23 includes a heat conducting plate 231 and a heat insulating layer 232. The heat insulating layer 232 is connected to the side of the heat conducting plate 231 away from the screw pump stator tube 5. A serpentine conduit 233 is arranged inside the heat conducting plate 231, and the serpentine conduit 233 is used to pass cold and hot fluids.

[0031] The heat conducting plate 231 is provided with a heating wire groove on one side close to the screw pump stator tube 5, and a heating wire 234 is connected in the heating wire groove. When the device is initially operated, the heating wire 234 can be energized for auxiliary heating to improve the heating efficiency and ensure rapid heating to the required temperature.

[0032] The heat conducting plate 231 is a metal heat conducting plate or a ceramic heat conducting plate. In this embodiment, a metal heat conducting plate is used.

When the first temperature regulating and heat-insulating component 2 has just completed the heating operation, the temperature of its internal pipeline is relatively high, and the cooling effect can be achieved by directly introducing cold fluid through the second temperature regulating and heat-insulating component 3. There is no need to wait for the overall cooling of the first temperature regulating and heat-insulating component 2, and the real-time performance of the temperature control is better.
