A continuous feeding and heat-insulating conveying device for homogenized membranes specifically designed for desulfurization wastewater.

Abstract

This utility model discloses a continuous feeding and heat-insulating conveying device for homogenized membranes specifically designed for desulfurization wastewater. It includes a frame and a conveyor mounted on the frame. The conveyor has several heating rollers, each comprising a support roller rotatably mounted on the frame, two pipes inserted into the support roller and rotatably engaged with it via bearings, a nut head fitted over the pipes, and a sealing element outside the pipes. The outer wall of the nut head is threadedly connected to the support roller, and the inner wall of the nut head is in contact with the outer wall of the pipes. When the support roller rotates, the nut head moves inward under the action of the threads, squeezing the sealing element so that it abuts against the bearing end to form a seal. The two pipes are used for injecting and discharging heat transfer medium to heat the conveyor belt. This application combines the heat transfer medium heating structure with the rollers inside the conveyor to achieve internal heating and heat preservation. However, since the rollers need to rotate, a nut head threadedly connected to the support roller is installed outside the pipes, along with a sealing element. When the support roller rotates, the nut head tightens inward, squeezing the sealing element and sealing the pipes at the bearing end where the support roller rotates.

Description

Technical Field

[0001] This utility model relates to a conveying device, specifically a continuous feeding and heat-insulating conveying device for homogenized membranes used in desulfurization wastewater. Background Technology

[0002] The homogeneous membrane for desulfurization wastewater is a type of membrane made of a single membrane material with a uniform cross-sectional physical structure. It is generally used for the treatment of desulfurization wastewater and can effectively remove suspended solids, heavy metal ions and acid and alkali substances. The treated water can be reused or discharged in compliance with standards.

[0003] In the process of manufacturing this film, the production line includes an extruder, a conveyor, a calender, a cooling roller assembly, and a winding machine in sequence. After the material is extruded by the extruder, it is conveyed to the calender by the conveyor, then calendered into a film, cooled and shaped, and finally wound up.

[0004] In the above process, the extruded material needs to be transported to the calender by a conveyor. Insulation is particularly important in this process because it can maintain the state of the extruded material and prevent it from hardening, which would affect the calendering. Patent application number CN201610698844.7 discloses an insulated belt conveyor, which regulates the temperature by setting an insulation cover and hot and cold water pipes. However, this patent places the insulation device at the bottom, so its effect is relatively poor. Utility Model Content

[0005] In view of the shortcomings of existing technologies where the heat preservation device is placed at the bottom of the conveyor belt, resulting in poor heat preservation effect, this utility model provides a continuous feeding and heat preservation conveying device for homogeneous membranes specifically for desulfurization wastewater.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A continuous feeding and heat-insulating conveying device for homogeneous membranes used in desulfurization wastewater includes a frame and a conveyor mounted on the frame. The conveyor has several heating rollers, each of which includes a support roller rotatably mounted on the frame, two pipes inserted into the support roller and rotatably engaged with it via bearings, a nut head sleeved outside the pipes, and a sealing element disposed outside the pipes. The outer wall of the nut head is threadedly connected to the support roller, and the inner wall of the nut head is in contact with the outer wall of the pipe. When the support roller rotates, the nut head moves inward under the action of the threads, squeezing the sealing element so that it abuts against the end of the bearing to form a seal. The two pipes are used for injecting and discharging heat medium to heat the conveyor belt of the conveyor.

[0008] Preferably, the support roller includes a middle cylinder located in the middle and end cylinders located at both ends, the diameter of the end cylinders being smaller than the diameter of the middle cylinder, and the pipes are arranged inside the end cylinders.

[0009] Preferably, the nut head is a hollow cylindrical structure with external threads and a smooth inner wall. Its outer end is provided with a radially outwardly extending annular tightening head, and the surface of the tightening head is provided with anti-slip texture.

[0010] Preferably, the conveyor includes drive rollers, heating rollers and a conveyor belt mounted on a frame. The drive rollers are located at both ends of the conveyor, the heating rollers are located between the two ends of the conveyor, and the conveyor belt is fitted between each drive roller and the heating roller.

[0011] Preferably, the conveyor includes a first horizontal section, an inclined section, and a second horizontal section, with a heating roller provided at the junction of the first horizontal section and the inclined section, and at the junction of the inclined section and the second horizontal section.

[0012] Preferably, the frame is equipped with a flat-bottomed U-shaped heat preservation cover, which covers the conveyor belt inside.

[0013] Preferably, the left end of the insulation cover is provided with a receiving hole or the left end of the conveyor belt extends beyond the left end of the U-shaped insulation cover for receiving materials.

[0014] Preferably, the seal is a packing material that can be deformed under pressure.

[0015] Compared with the prior art, the advantages of this utility model are: This application combines the heat medium heating structure with the roller inside the conveyor to achieve internal heating and heat preservation. However, since the roller needs to rotate, a nut head that is threadedly connected to the support roller is set on the outside of the pipe and a sealing element is set. When the support roller rotates, the nut head tightens and squeezes the sealing element, thus forming a seal at the bearing end of the pipe that is engaged with the rotating support roller.

Example

[0024] A continuous feeding and heat-insulating conveying device for homogenized membranes specifically designed for desulfurization wastewater, such as... Figure 1-5 As shown, the device includes a frame 10 and a conveyor 20 mounted on the frame 10. The conveyor 20 has several heating rollers 202. Each heating roller 202 includes a support roller 201 rotatably mounted on the frame 10, two pipes 200 inserted into the support roller 201 and rotatably engaged with the support roller 201 via bearings 205, a nut head 207 sleeved on the pipes 200, and a sealing element 206 disposed outside the pipes 200. The outer wall of the nut head 207 is threadedly connected to the support roller 201, and the inner wall of the nut head 207 is in contact with the outer wall of the pipes 200. When the support roller 201 rotates, the nut head 207 moves inward under the action of the thread, squeezing the sealing element 206 so that the sealing element 206 abuts against the end of the bearing 205 to form a seal. The two pipes 200 are used to inject and discharge heat medium to heat the conveyor belt 203 of the conveyor 20. This solution combines the heat medium heating structure with the roller inside the conveyor 20 to achieve internal heating and heat preservation. However, since the roller needs to rotate, a nut head 207 threadedly connected to the support roller 201 is set outside the pipe 200 and a sealing element 206 is set. When the support roller 201 rotates, the nut head 207 tightens and squeezes the sealing element 206, forming a seal at the end of the bearing 205 that is in rotation with the support roller 201.

[0025] Preferably, the support roller 201 includes a central cylinder 2021 and end cylinders 2022 at both ends. The diameter of the end cylinders 2022 is smaller than that of the central cylinder 2021, and the pipe 200 is disposed inside the end cylinders 2022. The end cylinders 2022 are rotatably connected to the frame 10 via support bearings. Both the central cylinder 2021 and the end cylinders 2022 are hollow cylindrical structures.

[0026] Preferably, the nut head 207 is a hollow cylindrical structure with external threads and a smooth inner wall. Its outer end is provided with a radially outward-extending annular tightening head, the surface of which has anti-slip texture. Initial tightening is achieved through the tightening head, and later, when the support roller 201 rotates, it drives the nut head 207 to move inward and press against the seal 206.

[0027] Preferably, the conveyor 20 includes a drive roller, a heating roller 202 and a conveyor belt 203 disposed on the frame 10. The drive roller is disposed at both ends of the conveyor 20, the heating roller 202 is disposed between the two ends of the conveyor 20, and the conveyor belt 203 is sleeved between each drive roller and the heating roller 202.

[0028] Preferably, the conveyor 20 includes a first horizontal section 2001, an inclined section 2002, and a second horizontal section 2003. A heating roller 202 is provided at the junction of the first horizontal section 2001 and the inclined section 2002, and at the junction of the inclined section 2002 and the second horizontal section 2003. One of the two drive rollers is driven by a motor.

[0029] Preferably, the frame 10 is equipped with a flat-bottomed U-shaped heat insulation cover 204, which covers the conveyor belt 203 inside. The heat insulation cover 204 is used to reduce heat loss from the top and provide a certain heat insulation effect.

[0030] Preferably, the left end of the heat insulation cover 204 is provided with a material receiving hole 2041 or the left end of the conveyor belt 203 extends beyond the left end of the U-shaped heat insulation cover 204 for receiving materials.

[0031] Preferably, the seal 206 is a packing material that can be deformed under pressure. The packing material is made of rice husks or straw, which has the characteristic of self-damaging sealing.
