Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a novel screw feeder pump. Background Technology

[0002] The screw feeder pump is a new generation product that integrates material steady flow conveying, weighing and metering, and quantitative control; it is suitable for continuous material metering and batching in various industrial production environments; it adopts a number of advanced technologies, is reliable in operation, and has high control accuracy; it is especially suitable for continuous metering and batching of materials in industries such as building materials, metallurgy, power, and chemicals. The material enters the screw feeder pump from the inlet, is conveyed by the screw conveyor blades, and is discharged from the outlet.

[0003] When existing screw feed pumps transport fluid materials in low-temperature environments, there is a risk of material agglomeration or even adhesion to the pipe wall and blockage. Furthermore, it is inconvenient to control the feed rate before transportation, which makes it impossible to guarantee continuous and uniform transportation. Therefore, this application proposes a novel screw feed pump. Utility Model Content

[0004] Based on this, it is necessary to provide a novel spiral feed pump to address the aforementioned technical problems. Through its overall structural design, the pump can heat the water in the tank and circulate the water by drawing it out through a suction hose and draining it back through a drainage hose. The suction and drainage hoses are designed to fit the heat exchange sleeve, facilitating heat transfer to the sleeve. The heat exchange sleeve then provides uniform heating to the periphery of the feed cylinder, reducing blockages caused by material agglomeration or adhesion. Heating also reduces material viscosity and improves conveying efficiency. Combined with the drive assembly, the pump controls the rotation and speed of the two guide shafts, thereby adjusting the feed rate and ensuring the continuity and stability of uniform material conveying.

[0022] As described in the background art, when existing screw feed pumps transport fluid materials in low-temperature environments, there is a risk that the materials may clump or even adhere to the pipe wall and cause blockage. Furthermore, it is inconvenient to control the feed rate before transportation, which makes it impossible to guarantee continuous and uniform transportation.

[0023] To solve this technical problem, this utility model provides a novel screw feeder pump, which is used for material conveying;

[0024] The system includes a support frame 1, a support platform 2 fixed to the outer side of one end of the support frame 1, a feeding cylinder 3 installed on the inner side of the support frame 1, a drive end mechanism 4 installed on the end of the support platform 2 away from the feeding cylinder 3, a closed top plate 7 fixed to the upper end of the support frame 1, a feeding funnel 5 fixed inside the closed top plate 7 and located inside the support platform 2, a stacking seat 15 fixed to the upper end of the feeding funnel 5, two guide shafts 17 rotatably connected to the inner side of the stacking seat 15, a drive assembly between the two guide shafts 17, a water tank 8 fixed to the lower end of the inner side of the support platform 2, a circulation pump 11 fixed to the upper end of the closed top plate 7 away from the feeding funnel 5, a water suction hose 12 and a drainage hose 13 respectively connected to the water inlet and outlet of the circulation pump 11, the ends of the water suction hose 12 and the drainage hose 13 away from the circulation pump 11 are equidistantly wound around the outer side of the feeding cylinder 3 and extend into the interior of the water tank 8.

[0025] The novel spiral feed pump provided by this utility model, through its overall structural design, can draw water from the water tank 8 through the suction hose 12 and then drain it back through the drainage hose 13 to achieve circulation. Furthermore, the suction hose 12 and drainage hose 13 are used to uniformly heat the periphery of the feed cylinder 3, reducing blockages caused by material agglomeration or adhesion within the feed cylinder 3. Heating also reduces material viscosity and improves conveying efficiency. In conjunction with the drive assembly, the rotation and speed control of the two guide shafts 17 are realized, thereby adjusting the feed rate and ensuring the continuity and stability of uniform material conveying.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Example 1:

[0029] Please refer to Figure 1-4A novel spiral feeder pump includes a support frame 1, a support platform 2 fixed to the outer side of one end of the support frame 1, a feed cylinder 3 installed on the inner side of the support frame 1, a drive end mechanism 4 installed at the end of the support platform 2 away from the feed cylinder 3, a closed top plate 7 fixed to the upper end of the support frame 1, a feed hopper 5 fixed inside the closed top plate 7 and located inside the support platform 2 to facilitate feeding material into the feed cylinder 3, and a discharge funnel 6 fixed at the lower end of the support frame 1 away from the feed funnel 5 to discharge the material conveyed by the feed cylinder 3, and a discharge funnel seat 6 fixed at the lower end of the support frame 1 away from the feed funnel 5, with the upper end of the discharge funnel seat 6 penetrating through the feed cylinder 3 and communicating with the feed cylinder 3.

[0030] Before the material is fed into the feeding hopper 5, in order to control the feeding amount and enable the material to be fed continuously, stably and quantitatively, a stacking base 15 is fixed at the upper end of the feeding hopper 5. Two guide shafts 17 are rotatably connected inside the stacking base 15, and a drive assembly is provided between the two guide shafts 17.

[0031] Specifically, the drive assembly includes a first support shaft 18 and a second support shaft 19. The first support shaft 18 and the second support shaft 19 are rotatably connected to one side of the stacking base 15 and located at the center of the two guide shafts 17. The first support shaft 18 and the second support shaft 19 are fixed to the two guide shafts 17 respectively. A spur gear 20 is fixed to the outside of the first support shaft 18 and the second support shaft 19 and located to the outside of the stacking base 15. A worm gear 21 is also fixed to the outside of the second support shaft 19. A reduction motor 22 is fixed to the upper end of the support platform 2. A worm 23 is fixed to the output end of the reduction motor 22. The worm 23 is meshed with the worm gear 21.

[0032] The rotation and speed of the two guide shafts 17 can be easily controlled by the drive component, and the feed rate can be controlled by the speed.

[0033] When conveying materials through the feed cylinder 3, in order to uniformly heat the periphery of the feed cylinder 3, reduce blockage caused by material agglomeration or adhesion inside the feed cylinder 3, and further reduce the viscosity of the material by heating to improve conveying efficiency, a water tank 8 is fixed at the lower end of the inner side of the support platform 2, and a circulation pump 11 is fixed at the upper end of the closed top plate 7 away from the feed funnel 5. The water inlet and outlet of the circulation pump 11 are respectively connected to a water suction hose 12 and a water drainage hose 13. The ends of the water suction hose 12 and the water drainage hose 13 away from the circulation pump 11 are equidistantly wrapped around the outside of the feed cylinder 3 and extend into the water tank 8.

[0034] In order to heat the water in the water tank 8 and ensure that the water temperature always meets the heating requirements, a water temperature monitoring module 9 and an electric heating module 10 are respectively installed on the outside of the water tank 8. The heating end of the electric heating module 10 extends into the water tank 8. The water temperature monitoring module 9 monitors the water temperature in the water tank 8 in real time. When the water temperature is lower than the requirement, the electric heating module 10 is controlled to heat the water.

[0035] All of the above electrical components are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that performs control, and the existing publicly available power connection technology will not be described in detail here.

[0036] Example 2:

[0037] The novel screw feeder pump provided in Example 1 has been further optimized, specifically, as follows: Figure 3-4 As shown, in order to make the heating effect more uniform, a heat exchange sleeve 14 is fixed on the outside of the feed cylinder 3 and inside the water suction hose 12 and the drain hose 13. The water suction hose 12 and the drain hose 13 are both in contact with the heat exchange sleeve 14. The contact between the water suction hose 12 and the drain hose 13 and the heat exchange sleeve 14 facilitates the transfer of heat to the heat exchange sleeve 14, and then the heat exchange sleeve 14 achieves uniform heating of the periphery of the feed cylinder 3.

[0038] In order to facilitate the flow of the falling material to the two guide shafts 17, a guide plate 16 is symmetrically fixed on the inner side of the stacking seat 15 and at the upper end of the two guide shafts 17. The stacking seat 15, the feed hopper 5 and the feed cylinder 3 are connected.

[0039] The novel spiral feeder pump provided by this utility model is used as follows: by starting the circulation pump 11, water in the water tank 8 is easily drawn out through the water suction hose 12, and then the drawn water is discharged to the drain hose 13 so that it returns to the water tank 8 to form a circulation. When the water flows through the water suction hose 12 and the drain hose 13, its heat is transferred to the heat exchange sleeve 14, and then the heat exchange sleeve 14 heats the periphery of the feed cylinder 3 evenly, reducing the blockage caused by material agglomeration or adhesion in the feed cylinder 3.

[0040] Before the material enters the feed hopper 5, it is guided by two guide plates 16 to fall and accumulate between two guide shafts 17. The reduction motor 22 is started to drive the worm 23 to rotate. The meshing of the worm 23 and the worm wheel 21 drives the second support shaft 19 to rotate. Then, the meshing of the two flat gears 20 drives the two guide shafts 17 to move relative to each other, so that the material is discharged through the gap between the two guide shafts 17 to achieve feeding. The feed rate can be adjusted by controlling the rotation speed of the two guide shafts 17 to ensure the continuity and stability of uniform material conveying.
