Description

Technical Field

[0001] This utility model relates to a pneumatic ash conveying pump that prevents clogging. Background Technology

[0002] Silo pumps, as key equipment in pneumatic ash conveying systems, play a vital role in industrial production. They mainly consist of an inlet valve, pump body, outlet valve, and related control systems. Through periodic opening and closing, the silo pump draws ash material into the pump body from the inlet, and then uses compressed air to transport the ash material to the designated location. It boasts advantages such as high conveying efficiency and long conveying distance, and is widely used in the conveying of fly ash, cement, and other ash materials in industries such as power, chemical, and building materials.

[0003] However, silo pumps often experience clogging problems during actual operation. The physical properties of the ash are a significant factor leading to clogging. For example, if the ash has uneven particle size, excessive moisture content, or high viscosity, it is prone to accumulating and agglomerating inside the silo pump, thus clogging the pump's outlet. Utility Model Content

[0004] The main purpose of this invention is to provide a clog-resistant pneumatic ash conveying silo pump to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A clog-resistant pneumatic ash conveying pump includes a pump body. An external gear ring is horizontally arranged inside the pump body and is rotatably connected to the pump body. A notch is provided on the side wall of the pump body to expose the edge of the external gear ring. The exposed part of the external gear ring meshes with a driving gear, which is fixed on the output shaft of a motor. A stirring rod is vertically arranged downward from the center of the inner side of the external gear ring, and the inner wall of the external gear ring and the stirring rod are connected by a connecting rod.

[0007] Preferably, the pump body is provided with an outwardly protruding external gear ring chamber.

[0008] Preferably, the upper and lower sides of the inner cavity of the outer gear ring are provided with convex rings, and multiple ball grooves are provided at intervals on the convex rings. Balls are provided in the ball grooves, and part of the ball extends out of the ball groove and abuts against the outer gear ring.

[0009] Preferably, the outer gear ring is provided with an annular groove for accommodating the protruding portion of the ball, and the ball abuts against the inner bottom surface of the annular groove.

[0010] Preferably, a sealing ring groove is provided on the inner side of the ball groove on the convex ring, and a sealing ring is provided in the sealing ring groove.

[0011] Preferably, the connecting rod is provided with a spiral blade.

[0012] Preferably, the outer side of the drive gear is provided with a protective shell that communicates with the notch of the pump body.

[0013] Preferably, the stirring rod extends downwards and reaches the middle position of the pump body outlet.

[0014] The beneficial technical effects of this utility model are as follows:

[0015] In the silo pump provided by this utility model, the power of the motor can be effectively transmitted to the external gear ring through the meshing relationship between the driving gear and the external gear ring, thereby driving the stirring rod to rotate. The stirring rod rotates inside the pump body, which can agitate the ash material, prevent the ash material from settling or accumulating in the pump body, ensure the uniformity and flowability of the ash material, and reduce the possibility of blockage.

[0024] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0025] like Figures 1-7 As shown, the anti-clogging pneumatic ash conveying pump provided in this embodiment includes a pump body 1. An external gear ring 2 is horizontally arranged inside the pump body 1. The external gear ring 2 is rotatably connected to the pump body 1. A notch 3 is provided on the side wall of the pump body 1 to expose the edge of the external gear ring 2. The exposed part of the external gear ring 2 is engaged with a drive gear 4. The drive gear 4 is fixed on the output shaft of the motor 5. A stirring rod 6 is vertically arranged downward at the center of the inner side of the external gear ring 2. The inner wall of the external gear ring 2 and the stirring rod 6 are connected by a connecting rod 7.

[0026] The power of the motor 5 can be effectively transmitted to the external gear ring 2 through the meshing relationship between the drive gear 4 and the external gear ring 2, thereby driving the stirring rod 6 to rotate. The stirring rod 6 rotates inside the pump body 1, which can agitate the ash material, prevent the ash material from settling or accumulating in the pump body 1, ensure the uniformity and flowability of the ash material, and reduce the possibility of blockage.

[0027] In practical use, the pump body 1 needs to be equipped with structures such as the feed valve, exhaust valve, and discharge valve, which can be achieved using existing technologies and will not be described in detail in this application.

[0028] In this embodiment, as Figure 1 As shown, the pump body 1 is provided with an outwardly protruding outer gear ring chamber 8, which provides a relatively independent and protected space for the outer gear ring 2, separating the outer gear ring 2 from the ash material inside the pump body 1 and ensuring normal operation.

[0029] In this embodiment, as Figure 3 As shown, both the upper and lower sides of the outer gear ring chamber 8 are provided with convex rings 9. Multiple ball grooves 10 are provided at intervals on the convex rings 9. Balls 11 are provided in the ball grooves 10. Parts of the balls 11 extend out of the ball grooves 10 and abut against the outer gear ring 2. The arrangement of the balls 11 changes the friction mode between the outer gear ring 2 and the outer gear ring chamber 8 from sliding friction to rolling friction during rotation, reducing the friction force between the two and facilitating rotation.

[0030] In this embodiment, as Figure 4 As shown, the external gear ring 2 is provided with an annular groove 12 for accommodating the protruding portion of the ball 11. The ball 11 abuts against the inner bottom surface of the annular groove 12. The presence of the annular groove 12 provides a clear accommodating space for the ball 11, allowing the ball 11 to accurately abut against the external gear ring 2 during operation and maintain a relatively stable position. This prevents the ball 11 from shifting or falling off during rotation, ensuring good support and friction reduction for the ball 11 on the external gear ring 2, and maintaining the stability and reliability of the rotation of the external gear ring 2.

[0031] In this embodiment, as Figure 3As shown, a sealing ring groove 13 is provided on the inner side of the ball groove 10 on the convex ring 9, and a sealing ring 14 is provided in the sealing ring groove 13, which can effectively seal the gap between the outer gear ring chamber 8 and the outer gear ring 2, preventing dust from contacting the outer gear ring 2 and affecting the rotation of the outer gear ring 2.

[0032] In this embodiment, as Figure 7 As shown, the connecting rod 7 is provided with a spiral blade 15. The presence of the spiral blade 15 enables the connecting rod 7 to generate a stronger stirring effect on the ash material when it rotates with the external gear ring 2, thereby better avoiding the occurrence of clogging problems.

[0033] In this embodiment, as Figure 1 As shown, a protective shell 16 is provided on the outside of the drive gear 4, which is connected to the notch 3 of the pump body 1 to prevent interference from external factors and ensure the meshing transmission of the drive gear 4 and the external gear ring 2. Bearings are provided on the upper and lower sides inside the protective shell 16 to ensure the rotation of the output shaft of the motor 5.

[0034] In this embodiment, as Figure 3 As shown, the stirring rod 6 extends downwards and reaches the middle of the discharge port of the pump body 1, which can directly stir the ash material near the discharge port, prevent the ash material from accumulating and blocking at the discharge port, and ensure that the ash material can be smoothly transported out.

[0035] In summary, in this embodiment, the power of the motor 5 in the silo pump provided by this embodiment can be effectively transmitted to the external gear ring 2 through the meshing relationship between the drive gear 4 and the external gear ring 2, thereby driving the stirring rod 6 to rotate. The rotation of the stirring rod 6 inside the pump body 1 can agitate the ash material, preventing the ash material from settling or accumulating inside the pump body 1, ensuring the uniformity and flowability of the ash material, and reducing the possibility of blockage.

[0036] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
