Description

Technical Field

[0001] This utility model belongs to the technical field of screw conveyors, specifically a screw conveyor with a heating function. Background Technology

[0002] A screw conveyor is a machine that uses a motor to drive a screw to rotate and push materials to achieve the purpose of conveying. Screw conveyors can convey horizontally, inclined or vertically, and have the advantages of simple structure, small cross-sectional area and good sealing performance. In terms of conveying form, they are divided into shafted screw conveyors and shaftless screw conveyors. In terms of appearance, they are divided into U-shaped screw conveyors and tubular screw conveyors.

[0003] Currently, when using screw conveyors to transport special materials, the materials are preheated. As a result, some screw conveyors adopt a single-wall design, and the heat generated by heating dissipates quickly from the single-layer surface, resulting in poor heat preservation and energy waste. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a screw conveyor with heating function, which solves the problem that the heat generated by heating is quickly dissipated from the single-layer surface of the screw conveyor, resulting in poor heat preservation and thus energy waste.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screw conveyor with heating function, including a conveying pipe, a heating water tank is provided on one side of the conveying pipe, a heating wall is provided on the conveying pipe, an upper heat insulation cover and a lower heat insulation cover are installed on the heating wall of the conveying pipe, a support frame is connected to both the conveying pipe and the lower heat insulation cover, a feed inlet is connected to the top of the conveying pipe, and a discharge outlet is connected to the bottom of the conveying pipe;

[0006] An installation plate is connected to the transport pipe, a drive motor is installed on the installation plate, a connecting shaft is connected to the output shaft of the drive motor, a spiral blade is connected to the connecting shaft, a liquid pump is installed on the heating water tank, a return pipe is connected to the heating water tank, and a delivery pipe is connected to the liquid pump.

[0007] As a further embodiment of this utility model: a heating tube is fitted on the heating wall, the heating tube is designed in a spiral shape, and insulation cotton material is provided on the inner walls of both the upper and lower insulation covers.

[0008] As a further embodiment of this utility model: the return pipe is connected to one end of the heating pipe, and the delivery pipe is connected to the other end of the heating pipe.

[0009] As a further embodiment of this utility model: a pull rod is connected above the upper heat insulation cover, and connecting blocks are connected to both sides of the upper heat insulation cover. The connecting blocks are L-shaped and have fixing grooves.

[0010] As a further embodiment of this utility model: the lower heat insulation cover is connected to two sides by fixing blocks, the fixing blocks are provided with slots, the fixing blocks are slidably connected to connecting plates, the connecting plates are connected to wedge blocks, and the connecting blocks are inserted into the slots.

[0011] As a further embodiment of this utility model: the wedge block is designed with an inclined surface and inserted into the fixing groove; the connecting plate is T-shaped and sleeved with a spring; one end of the spring is connected to the fixing block, and the other end of the spring is connected to the wedge block.

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

[0013] 1. This screw conveyor with heating function is equipped with an upper insulation cover, a lower insulation cover, a pull rod, a connecting block, a slot, a wedge block, a connecting plate, a spring, and a fixing groove. The operator presses down on the upper insulation cover by pulling the pull rod, causing one end of the connecting block to be inserted into the slot. During the insertion process, the connecting block pushes the connecting plate through the inclined surface of the wedge block, causing the connecting plate to slide on the fixing block and causing the wedge block to compress the spring. After the connecting block contacts the fixing block, the spring rebound causes the wedge block to be locked into the fixing groove, thus fixing the upper and lower insulation covers together. This insulates the heated wall area, reduces heat waste, and is simple and convenient to install and operate.

[0014] 2. This screw conveyor with heating function is equipped with a liquid pump, conveying pipe, heating pipe, heating wall, return pipe, drive motor and screw blades. When the drive motor is started, it drives the connecting shaft to rotate, which in turn causes the screw blades to rotate and push the material to move. At this time, the liquid pump draws hot water from the heating water tank and delivers it to the heating pipe through the conveying pipe, thereby heating the heating wall to complete the preheating. Afterwards, the hot water will flow back into the heating water tank through the return pipe for heating, thus realizing recycling and improving utilization efficiency. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a screw conveyor with heating function, including a conveying pipe 1, a heating water tank 2 is provided on one side of the conveying pipe 1, a heating wall 3 is provided on the conveying pipe 1, and a heating pipe 16 is sleeved on the heating wall 3. The heating pipe 16 is designed in a spiral shape. Insulation cotton material is provided on the inner walls of the upper insulation cover 4 and the lower insulation cover 5. The spiral heating pipe 16 extends the flow distance of hot water and increases the contact area, while the upper insulation cover 4 and the lower insulation cover 5 can keep the heat warm and reduce waste.

[0022] An upper insulation cover 4 and a lower insulation cover 5 are installed at the heating wall 3 of the transport pipe 1. Fixing blocks 20 are connected to both sides of the lower insulation cover 5. Slots 21 are opened on the fixing blocks 20. A connecting plate 22 is slidably connected to the fixing blocks 20. A wedge block 23 is connected to the connecting plate 22. The connecting block 18 is inserted into the slot 21. By connecting the connecting block 18 and the slot 21, the staff can quickly complete the positioning and installation of the upper insulation cover 4 and the lower insulation cover 5. The operation is simple.

[0023] Both the transport pipe 1 and the lower insulation cover 5 are connected to a support frame 6. A pull rod 17 is connected to the top of the upper insulation cover 4. Connecting blocks 18 are connected to both sides of the upper insulation cover 4. The connecting blocks 18 are L-shaped and have fixing grooves 19. The support frame 6 supports and fixes the transport pipe 1 and the lower insulation cover 5, while the pull rod 17 on the upper insulation cover 4 can help the staff to press down or pull the upper insulation cover 4.

[0024] The wedge block 23 is designed with an inclined surface and is inserted into the fixing groove 19. The connecting plate 22 is T-shaped and is fitted with a spring 24. One end of the spring 24 is connected to the fixing block 20, and the other end of the spring 24 is connected to the wedge block 23. The wedge block 23 is inserted into the fixing groove 19 by the elastic force of the spring 24. The operation is simple and convenient, which facilitates the subsequent installation and disassembly by the staff, thereby facilitating maintenance and repair. The wider side of the T-shape of the connecting plate 22 can restrict the movement of the connecting plate 22 and prevent it from slipping and falling off.

[0025] A feed inlet 7 is connected to the top of the conveying pipe 1, and a discharge outlet 8 is connected to the bottom of the conveying pipe 1. A mounting plate 9 is connected to the conveying pipe 1, and a drive motor 10 is mounted on the mounting plate 9. The output shaft of the drive motor 10 is connected to a connecting shaft 11, and a spiral blade 12 is connected to the connecting shaft 11. A liquid pump 13 is installed on the heating water tank 2, and a return pipe 14 is connected to the heating water tank 2. A delivery pipe 15 is connected to the liquid pump 13. One end of the return pipe 14 is connected to the heating pipe 16, and the other end of the delivery pipe 15 is connected to the heating pipe 16. Through the cooperation of the liquid pump 13, the return pipe 14, and the delivery pipe 15, the hot water in the heating pipe 16 can circulate, thereby improving the utilization efficiency.

[0026] The working principle of this utility model is as follows:

[0027] The staff uses the pull rod 17 to press the upper insulation cover 4 down onto the lower insulation cover 5. During the pressing process, the connecting block 18 is inserted into the slot 21, and at the same time, the inclined surface of the wedge block 23 pushes the connecting plate 22, causing the connecting plate 22 to slide on the fixing block 20, and causing the wedge block 23 to compress the spring 24. After the connecting block 18 contacts the fixing block 20, the spring 24 rebounds and pushes the wedge block 23 into the fixing groove 19, so that the upper insulation cover 4 and the lower insulation cover 5 are combined and fixed together, thereby covering and insulating the area of ​​the heating wall 3. During operation, the drive motor 10 is started to drive the spiral blade 12 to rotate to complete the material transportation, while the liquid pump 13 will draw the hot water from the heating water tank 2 and deliver it to the heating pipe 16 through the delivery pipe 15, thereby heating the heating wall 3 to complete the preheating. Afterwards, the hot water will flow back into the heating water tank 2 through the return pipe 14.
