Description

Technical Field

[0001] The utility model relates to the technical field of graphite production, in particular to a dust collecting pipe head. Background Art

[0002] like Figure 5 The dust collecting pipe head includes a dust collecting tank, which is screwed and fixed to the connecting pipe of the dust collecting tank. The connecting pipe is fixed to the conveying pipe by welding or other methods. The dust collecting tank is used to collect and store graphite deposited in the conveying pipe. During use, as the dust collecting tank is used for a longer time, the material in the dust collecting tank increases, so it needs to be cleaned regularly. The existing cleaning method is to first loosen the screw, then remove the dust collecting tank, and then clean the interior. This operation method is relatively cumbersome and increases the workload of the operator. Utility Model Content

[0003] The utility model provides a dust collecting pipe head to solve the above-mentioned deficiencies in the prior art, and solves the problem that the dust collecting tank is difficult to clean and the operation is complicated, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] A dust collecting pipe head includes a collecting tank installed on a pipe by multiple screws. A conical cavity is formed at the lower end of the interior of the collecting tank. A circular hole is opened at the lower end of the conical cavity. The diameter of the lower end of the conical cavity is smaller than the diameter of the upper end. The setting of the conical cavity facilitates the discharge of substances contained in the collecting tank.

[0006] A conical head is provided at the lower end of the interior of the collecting tank. The lower end of the conical head is the small end, and the taper of the conical head is equal to the taper of the conical cavity. A connecting column is provided at the lower end of the connecting column. A rotating rod is provided at the lower end of the connecting column. The connecting column passes through the circular hole, and an end cap is provided at the lower end of the rotating rod. The conical head acts on the inner wall of the conical cavity, thereby sealing the lower end of the conical cavity to avoid powder leakage. When the contained substance is discharged, the conical head can be pushed upward to facilitate the discharge operation of the contained substance.

[0007] Furthermore, a conical piece is provided at the upper end of the conical head, and the upper end of the conical piece is a small end, and the provided conical piece plays a role in guiding the powder.

[0008] Furthermore, a plurality of scrapers are provided at the upper end of the conical member, the outer walls of the scrapers are tangent to the inner wall of the conical cavity, and the scrapers are rotated to scrape off the powder adhering to the conical cavity, thereby facilitating the discharge operation of the powder.

[0009] Furthermore, the outer wall of the scraper is a blade-shaped structure to improve the cleaning effect on the inner wall of the tapered cavity.

[0010] Furthermore, a pair of limiting rings are provided on the rotating rod, a rotating sleeve is provided between the limiting rings, a pair of lifting rods are provided on the outer circumference of the rotating sleeve, a rotating boss is installed at the lower end of the collecting tank, and a pair of rotating plates are rotatably provided at the lower end of the rotating boss, a waist-shaped hole is provided on the rotating plate, and the lifting rod is passed through the waist-shaped hole, and a connecting end plate is provided at the other end of the rotating plate, and a handle is provided on the connecting end plate. The rotating plate can be rotated to make the lifting rod move upward, thereby making the conical head move upward, and then canceling the sealing of the conical cavity by the conical head. This operation method is convenient for lifting the conical head upward, thereby facilitating the discharge operation of the collected material.

[0011] Furthermore, a guide rail is installed at the lower end of the collection tank, and a sliding sleeve is slidably provided on the guide rail. The lower end of the sliding sleeve is provided with a concave frame, and the lower end of the concave frame is penetrated by a pair of spring pins, and the lower end of the spring pin is provided with a connecting plate, and the lower end of the connecting plate is provided with an arc plate, the inner periphery of the arc plate is tightly attached to the handle, and the lower end of the spring pin is sleeved with a spring, which is located at the lower end of the concave frame. When it moves inward through the arc plate, it can act on the handle, thereby making the conical head tightly attached to the inner wall of the conical cavity, thereby improving the sealing effect.

[0012] Furthermore, an inner top rotating plate is rotatably provided at the outer end of the guide rail, and the inner end of the inner top rotating plate acts on the sliding sleeve. A rotating vertical rod is provided at the outer end of the inner top rotating plate.

[0021] like Figures 1 to 5 As shown, a dust collecting pipe head includes a collection tank 1 mounted on a pipe 9 via multiple screws. A conical cavity 10 is formed at the lower end of the collection tank 1. A circular hole 11 is formed at the lower end of the conical cavity 10. The diameter of the lower end of the conical cavity 10 is smaller than the diameter of the upper end. A conical head 2 is provided at the lower end of the collection tank 1. The lower end of the conical head 2 is a small end, and the taper of the conical head 2 is equal to the taper of the conical cavity 10. A connecting column 22 is provided at the lower end of the connecting column 22. A rotating rod 23 is provided at the lower end of the connecting column 22. The connecting column 22 passes through the circular hole 11. The lower end of the rotating rod 23 is provided with an end cap 25. The upper end of the conical head 2 is provided with a conical member 20. The upper end of the conical member 20 is provided with multiple scrapers 21. The outer wall of the scrapers 21 is tangent to the inner wall of the conical cavity 10, and the outer wall of the scrapers 21 has a blade-shaped structure.

[0022] A pair of limiting rings 24 are mounted on the rotating rod 23. A rotating sleeve 3 is mounted between the limiting rings 24. A pair of lifting rods 30 are mounted on the outer circumference of the rotating sleeve 3. A rotating boss 31 is mounted on the lower end of the collection tank 1. A pair of rotating plates 32 are rotatably mounted at the lower end of the rotating boss 31. The rotating plates 32 have waist-shaped holes 33 formed in them, through which the lifting rods 30 pass. The other end of the rotating plates 32 is equipped with a connecting end plate, which is provided with a handle 34. A guide rail 35 is mounted on the lower end of the collection tank 1. A sliding sleeve is slidably mounted on the guide rail 35. The lower end of the sliding sleeve is provided with a concave frame 36. A pair of spring pins 37 are mounted on the lower end of the concave frame 36. The lower end of the spring pins 37 is provided with a connecting plate 39.

A rotating vertical rod 42 is provided at the outer end of the inner top rotating plate 41 .

[0023] During operation of this embodiment, the operator first rotates the inner top rotating plate 41 outward to cancel the position restriction of the sliding sleeve by the inner top rotating plate 41 .

[0024] Then the operator moves the sliding sleeve outward and cancels the limiting operation of the arc plate 40 on the handle 34 .

[0025] Then the operator rotates the rotating rod 23 . When the rotating rod 23 rotates, the scraper 21 thereon rotates. When the scraper 21 rotates, it acts on the conical cavity 10 , thereby scraping off the powder on the conical cavity 10 through the scraper 21 .

[0026] The operator then rotates the rotating plate 32 upward by means of the handle 34 to move the rotating rod 23 and the conical head 2 upward until the rotating rod 23 is located at the circular hole 11 , after which the material in the conical cavity 10 is discharged downward through the circular hole 11 .

[0027] After discharge, the position of the conical head 2 is fixed.
