Description

Technical Field

[0001] This utility model belongs to the field of pipeline dredging technology, specifically relating to a PMMA particle conveying pipeline dredging device. Background Technology

[0002] The PMMA used in PMMA particle conveying pipes is polymethyl methacrylate, also known as plexiglass or acrylic. During particle conveying, especially in high-temperature or high-humidity environments, PMMA particles tend to adhere to the inner wall of the conveying pipe, forming aggregates. Some PMMA particles may also generate static electricity during conveying, causing them to attract each other and clump together, thus clogging the pipe.

[0003] Currently, an air gun-type pipe cleaning device with announcement number CN201217830Y is available on the market. Inside the gun bed (1), a positioning head (2) is fixed at its left end. An air spring (8) is sleeved on the positioning head (2) and placed inside the piston (7). A piston sealing ring (9) is sleeved on the right end of the piston (7) and placed inside the air cylinder (4). A sealing gasket (12) is placed between the right end of the air cylinder (4) and the gun bed (1). The upper lever (15) is fixed to the upper left part of the gun bed (1) by a pin (6) and is connected to the push rod (3) and the air cylinder (4). The trigger (10) and the air guide tube (13) are fixed on the gun bed (1). A rubber cup (16) is fixed at the right end of the gun bed (1). This utility model is small in size, easy to use and store; it is lightweight and labor-saving, especially suitable for the elderly, women and other people with less strength; it has a simple structure and is easy to manufacture and maintain.

[0004] The pneumatic pipe cleaner, with announcement number CN204475457U, includes an air pump, a piston cup, an air storage chamber, a connecting hose, and a connecting steel pipe. The air storage chamber has a one-way valve at its inlet and a control valve at its outlet. A pressure gauge and an exhaust switch are located outside the control valve. The bottom of the air pump is threaded to the one-way valve. The control valve is connected to the inlet of the connecting steel pipe via the connecting hose, and the outlet of the connecting steel pipe is connected to the piston cup. This invention features a detachable connection between the air pump, air storage chamber, connecting hose, and connecting steel pipe, facilitating storage. The invention allows for gas storage via the one-way valve, monitoring of the actual pressure via the pressure gauge, and instantaneous release of the stored gas, achieving high-pressure gas pipe cleaning and extending the cleaning distance. Furthermore, the use of a valve core-type exhaust switch minimizes gas loss.

[0005] However, there is a problem: the length of the unblocking pipe of this device cannot be adjusted, and it cannot clean the internal areas that need cleaning. Utility Model Content

[0006] This solution provides a PMMA particle conveying pipeline unblocking device to solve the problem of unblocking pipes having no adjustable length.

[0007] This solution provides a PMMA particle delivery pipeline unblocking device, including an air pump; an air gun: the air gun and the air pump are connected through a transparent pipe; and an unblocking mechanism: the unblocking mechanism cooperates with the air gun and is used to unblock the inside of the pipeline; the unblocking mechanism includes: an outer tube: the outer tube is coaxially and fixedly connected to the air nozzle of the air gun; and an inner tube: the inner tube is coaxially and slidably connected to the outer tube, and the diameter of the inner tube is smaller than that of the outer tube, and the inner tube cooperates with the air nozzle.

[0008] The principle behind this solution is as follows: When unblocking is needed, the operator simply inserts the outer tube into the channel, starts the air pump, and then opens the air gun to inflate the pipe. The gas rushes out from the inner tube, impacting the blockage and clearing the blockage. When the blockage is closer to the inside, the operator can pull the inner tube to extend it, increasing the overall length of the unblocking mechanism and allowing the gas to be concentrated and delivered further with greater force.

[0009] The beneficial effects of this solution are: the length of the unblocking mechanism can be adjusted, allowing for concentrated air jet cleaning of blockages that are too far away.

[0010] Furthermore, it also includes drain plugs, which are fixedly connected to the external pipe. Multiple drain plugs are arranged in a circumferential array around the external pipe. When encountering stubborn blockages that are difficult to remove with air pressure, this mechanism adds a ring of drain plugs at the end of the external pipe. When encountering blockages that are difficult to remove, the operator can use the drain plugs to knock them away. This mechanism combines physical and air pressure methods, making pipe unblocking more flexible.

[0011] Furthermore, it also includes a locking mechanism, which includes a locking pin and a spring. The outer tube has a through hole, the locking pin is slidably connected to the through hole, one end of the spring is fixedly connected to the outer tube, and the other end is fixedly connected to the locking pin. The inner tube has a cone head, which cooperates with the locking pin.

[0012] When the inner tube extends, if it is not locked, it can easily retract during the unblocking process, thus failing to achieve the desired extension effect. With this solution, when the operator pulls out the inner tube, the cone-shaped end of the inner tube also moves and contacts the locking post. The locking post is pushed back by the cone surface, allowing the cone-shaped end to pass through. Then, the locking post returns to its original position under the action of a spring, locking the cone-shaped end in place. This prevents the inner tube from retracting during use.

[0013] Furthermore, it also includes a sliding disc and a limiting rod. The sliding disc is coaxially fixedly connected to the inner tube, the sliding disc is slidably connected to the outer tube, the limiting rod is fixedly connected to the sliding disc, the outer tube is provided with a vertical groove, the limiting rod cooperates with the vertical groove, the through hole communicates with the vertical groove, and the limiting rod is provided with a cone head, which is slidably connected to the vertical groove.

[0014] If the internal tube rotates, the cone head will misalign with the locking pin, causing locking failure. Therefore, this mechanism has a vertical groove in which the cone head slides, preventing the internal tube from rotating. This prevents locking failure. Attached Figure Description

[0019] As attached Figure 1 , Figure 2 As shown:

[0020] This solution provides a PMMA particle delivery pipeline unblocking device, including an air gun 1, an air pump, and an unblocking mechanism. The air gun 1 is connected to the air pump via a transparent pipe 4. The air gun 1 is equipped with an air valve 2 and a compressed air switch 3. The operator needs to open the air valve 2 and then press the compressed air switch 3 to allow the air pump to supply air to the nozzle. The nozzle of the air gun 1 is fixedly connected to an external pipe 5, and the nozzle and the external pipe 5 are coaxially arranged, with the nozzle located inside the external pipe 5. An internal pipe 6 is slidably arranged coaxially with the external pipe 5, and the diameter of the internal pipe 6 is smaller than that of the external pipe 5.

[0021] The outer tube 5 is a hollow round tube with an inner diameter of 2cm, and the inner tube 6 is a hollow round tube with an outer diameter of 1.8cm. Both tubes are 50cm long. The hollow round tube with an outer diameter of 1.8cm is installed inside the hollow round tube with an inner diameter of 2cm. A buckle is installed at the end of the outer tube for fixing when the inner tube expands or contracts. A row of drain nails 7 with a gap of 5cm, a length of 3cm, and an area of ​​0.5cm x 0.5cm is welded at the end of the outer tube.

[0022] As attached Figure 3 As shown:

[0023] The inner tube 6 has a sliding disc 8 at its left end. The sliding disc 8 slides in contact with the outer tube 5. The sliding disc 8 is used to limit the vertical and horizontal displacement of the inner tube 6. The outer tube 5 has two vertical grooves 9. The sliding disc 8 has two limiting rods 10. The limiting rods 10 are located inside the grooves and are used to limit the rotation of the inner tube 6.

[0024] The limiting rod 10 is also equipped with a cone 13, which is smaller at the top and larger at the bottom. The outer tube 5 is also equipped with a through hole that connects to the vertical groove 9. The locking post 11 is slidably connected to the through hole. One end of the spring 12 is fixedly connected to the outer tube 5, and the other end is fixedly connected to the locking post 11. Under the action of the spring 12, the locking post 11 is located inside the vertical groove 9. When the cone 13 is pushed over, it will be pushed outward under the action of the cone 13. After passing the cone 13, it will be locked below the cone 13 under the action of the spring 12, which plays a locking role.

[0025] As attached Figure 1 , Figure 2 , Figure 3 As shown:

[0026] The principle of this solution is as follows: when the flared opening is blocked, the inner round tube is placed inside the outer round tube, and the end of the outer round tube is used to physically impact the blocked opening. The compressed air inside the inner round tube is then opened to blow away the blockage, thereby clearing the flared opening.

[0027] When the desiccant hemisphere is clogged, first insert the unblocking pin 7 at the end of the outer tube to clear the blockage. Then pull out the inner tube from the outer tube. The cone 13 of the inner tube 6 will also move and contact the retaining post 11. The retaining post 11 is pushed back by the cone surface, allowing the cone 13 to pass through. Then, the retaining post 11 returns to its original position under the action of the spring 12, locking the cone 13. This prevents the inner tube 6 from retracting during use. Turn on the compressed air switch 3 to use compressed air from the inner tube to purge and clear the blockage.

[0028] The beneficial effects of this solution are as follows: 1. The unblocking mechanism of this solution is length-adjustable, enabling concentrated air jet cleaning of blockages that are too far away. 2. The new unblocking tool produced using novel PMMA particles can quickly and efficiently unclog conveying pipes and dryers, thereby maintaining the normal operation of the production line. 3. The locking mechanism prevents the internal pipe 6 from retracting.
