Description

Technical Field

[0001] The present application belongs to the field of mechanical technology, and specifically relates to a screw-type anti-blocking discharge valve. Background Art

[0002] Because there are more particulate materials in the production process, the materials in the kettle need to be put into a filter to filter out the residue to obtain a clarified product. The use of conventional discharge valves or upward discharge valves cannot solve the blockage problem. Some particles will be blocked in the straight pipe section between the bottom of the kettle and the discharge valve and cannot be discharged.

[0003] For example, the patent CN210068952U provides an improved upward-expanding kettle bottom discharge valve, which has a baffle movably connected to the bottom of the body cavity, which has the effect of blocking the material, a valve stem is fixedly connected to the middle end of the baffle top, and a balance plate is fixedly connected to the top of the valve stem, which has the effect of regulating, and a feed inlet is opened at the lower end of the right side of the body, which has the effect of preventing blockage. However, during the process of putting in granular materials, there will still be too much material accumulation, which will block the connection port of the discharge pipe, and the material cannot be discharged in time.

[0006] Furthermore, the lifting screw assembly includes a threaded rod, and a propeller blade is provided on the lower half of the threaded rod.

[0007] Furthermore, the baffle is fixedly connected to the bottom of the threaded rod, and the top of the threaded rod is fixedly connected to a limit plate located outside the first material pipe.

[0010] Furthermore, the driving motor is fixedly connected to the seat plate and is located at the side end of the annular base, and a driving gear meshing with the annular gear is provided at the end of the driving shaft of the driving motor.

[0011] The beneficial effects of the present application are as follows: the lifting and lowering of the threaded rod in the present application controls the start and stop of material transportation. When the material is blocked in the second pipe, the particulate material in the second pipe can be cleared by lowering the propeller blades, and the material discharge speed can be effectively controlled.

[0015] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0016] See also Figure 1-3 A screw-type anti-blocking discharge valve comprises a first material pipe 1 arranged vertically and a second material pipe 2 obliquely connected to the side wall of the first material pipe 1; the second material pipe 2 is connected to the first material pipe 1; a lifting screw assembly 3 is arranged in the inner cavity of the first material pipe 1, a baffle 4 is arranged at the bottom of the lifting screw assembly 3, and a sealing ring connected to the inner wall of the first material pipe 1 is arranged on the outer ring of the baffle 4; wherein a driving motor 5 for controlling the lifting and lowering of the lifting screw assembly 3 is arranged at the top of the first material pipe 1. The lifting screw assembly 3 in the above design can be lowered to the bottom of the second material pipe 2 when feeding stops, closing the feeding port, and when feeding is needed, it rises to the upper side of the second material pipe 2 to open the feeding port.

[0017] The lifting screw assembly 3 includes a threaded rod 31, and a propeller blade 32 is provided at the lower half of the threaded rod 31. The propeller blade 32 in the above design can clear the material blocked between the first material pipe 1 and the second material pipe 2, and can rotate and descend to the lower side of the first material pipe 1, thereby driving the material to be discharged in real time.

[0018] The baffle 4 is fixed to the bottom of the threaded rod 31, and the top of the threaded rod 31 is fixed to the limit plate 33 located outside the first material pipe 1. The baffle 4 in the above design is used to block the material from being thrown down. The limit plate 33 can prevent the threaded rod 31 from falling off when it drops to the lowest point.

[0019] The outer diameter of the propeller blade 32 is the same as the outer diameter of the baffle 4. The above design makes the distance between the propeller blade 32 and the inner wall of the first material pipe 1 as small as possible to prevent the propeller blade 32 from being stuck by the material.

[0020] The top of the first material tube 1 is fixedly connected with a seat plate 6, in which an annular base 7 is provided, on which an annular gear 8 is movably provided, and the upper half of the threaded rod 31 is sequentially inserted into the seat plate 6, the annular base 7 and the annular gear 8, wherein the thread of the threaded rod 31 is meshed with the inner teeth of the annular gear 8. The rotation of the annular gear 8 in the above design can be engaged with the thread of the threaded rod 31 through the inner teeth 81, thereby driving the threaded rod 31 to rise and fall.

[0021] The driving motor 5 is fixedly connected to the seat plate 6 and is located at the side end of the annular base 7. The driving shaft end of the driving motor 5 is provided with a driving gear 51 meshing with the annular gear 8. In the above design, the driving motor 5 is used to rotate through the driving gear 51, thereby driving the annular gear 8 to rotate.

[0022] The specific working principle, such as Figure 1 When feeding is not needed, the driving motor 5 rotates to make the threaded rod 31 descend, and the baffle 4 descends to a position lower than the interface of the second material pipe 2, thereby closing the feeding port; when feeding is needed, the driving motor 5 rotates to make the threaded rod 31 ascend, and the baffle 4 ascends to a position higher than the interface of the second material pipe 2, thereby opening the feeding port. Figure 2 When the material particles are blocked at the interface between the second material pipe 2 and the first material pipe 1, the threaded rod 31 is controlled to continue to descend until the lowest point, and the baffle 4 extends out of the bottom of the first material pipe 1. At this time, the ring gear 8 clamps the limit plate 33, thereby driving the threaded rod 31 and the propeller blade 32 to rotate. The propeller blade rotates to clear the material at the interface between the second material pipe 2 and the first material pipe 1. The material descends with the propeller blade and flows out of the bottom of the first material pipe 1. In addition, by controlling the rotation speed of the propeller blade 32, the material discharge speed can be controlled in real time.

[0023] The above description is only an embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
