Technical Field

[0001] The utility model relates to the technical field of petroleum gas filtering, in particular to a liquefied petroleum gas purification and filtering device for petrochemical industry. Background Art

[0002] Liquefied petroleum gas filtering device, commonly known as liquefied gas filter, is an important device to ensure that liquefied petroleum gas (LPG) is pure and free of impurities during transportation and use; the filtering device is usually installed at the inlet end of the pressure reducing valve, pressure relief valve, positioning valve or other equipment to eliminate impurities in the medium to protect the normal use of the valve and equipment; when the fluid enters the filter with a filter element, its impurities are blocked by the filter element, and the clean filtered gas is discharged from the filter outlet.

[0003] During the long-term operation of the existing liquefied petroleum gas filter, the impurities and particles accumulated on the filter element will gradually reduce the filtering effect, which may lead to the problem of obstruction of petroleum gas discharge. Such accumulated impurities not only affect the circulation efficiency of petroleum gas, but also may have an adverse effect on the quality of petroleum gas. In more serious cases, it may cause potential safety hazards and threaten the safety of the use environment and personnel.

[0004] Therefore, it is urgent to provide a liquefied petroleum gas purification and filtering device for petrochemical industry to solve the above problems. Utility Model Content

The design that the smooth part of the gear has teeth makes it possible to drive the rack to move through the meshing of the teeth and the rack when the handle is rotated, while the smooth part of the gear can cause the rack to lose meshing. This design is conducive to the reciprocating motion of the rack. When the rack is pulled back to its original position under the action of the spring, it hits the filter element to shake off impurities on the filter element, thereby achieving the purpose of cleaning the filter element.

[0030] See also Figure 1-Figure 2 As shown, the purpose of this embodiment is to provide a liquefied petroleum gas purification and filtering device for petrochemical industry, including a delivery pipe and a filtering mechanism connected thereto, wherein the filtering mechanism includes a filtering barrel 1, and a filter element 9 connected to the delivery pipe is arranged in the filtering barrel 1.

[0031] For further information, see Figure 2-Figure 4 As shown, two slide grooves 7 are symmetrically arranged in the filter barrel 1, and a filter screen 8 for impacting the filter element 9 is slidably connected in the slide groove 7. The filter screen 8 realizes reciprocating sliding in the slide groove 7 under the support of the support 6 through the shaking component 5;

[0032] An ash discharge port 2 is provided at the bottom of the filter barrel 1 just below the filter element 9 , and an ash collecting bucket 3 is fixedly sleeved on the ash discharge port 2 via a locking assembly 4 , and the locking assembly 4 is used to realize the detachable installation of the ash collecting bucket 3 .

[0033] For further information, see Figure 3-Figure 4As shown, the shaking assembly 5 includes a connecting rod 51 with one end fixedly connected to the filter screen 8, and the other end fixedly connected to the rack 53. The connecting rod 51 is slidably connected with a support 6, and the support 6 is fixedly connected to the filter barrel 1. A spring 52 is sleeved on the connecting rod 51, and one end of the spring 52 is fixedly connected to the filter screen 8, and the other end is fixedly connected to the support 6. The rack 53 is meshed with a gear 54, and the gear 54 is fixedly connected to one end of a rotating rod 56. A sealed bearing 55 is rotatably connected to the rotating rod 56, and the sealed bearing 55 is fixedly connected to the filter barrel 1. The other end of the rotating rod 56 passes through the filter barrel 1, and the end thereof exposed outside the filter barrel 1 is fixedly connected to a handle 57; by rotating the handle 57, the gear 54 can be driven. Since the gear 54 is partially smooth and partially has teeth, its rotation drives the rack 53 meshing with it to move forward, thereby driving the connecting rod 51 connected to the filter screen 8 to slide in the slide groove 7. When the gear 54 rotates to the smooth part, the rack 53 will lose its meshing with the gear 54 and be pulled back to its original position under the action of the spring 52, and hit the filter element 9, so that the impurities on the filter element 9 are shaken off to the ash discharge port 2 below, and discharged into the ash collecting bucket 3 through the ash discharge port 2.

[0034] For details, please refer to Figure 4 As shown, only a portion of the outer circumference of the gear 54 has teeth, and the rest is smooth.

[0035] For further information, see Figure 3 and Figure 5 As shown, the locking assembly 4 includes a base 41, and the locking rod 42 is rotatably connected inside the base 41, the locking rod 42 is meshed with a locking ring 43, the locking ring 43 passes through the base 41 to form a circular ring, and is slidably connected thereto, and a sealing ring 44 is provided inside the locking ring 43 for being sleeved on the port of the ash collecting bucket 3; the locking rod 42 is rotated and meshed with the locking ring 43, so that rotating in the opposite direction will enlarge the locking ring 43, thereby loosening the connection between the ash collecting bucket 3 and the ash discharge port 2, and the ash collecting bucket 3 can be removed for disposal.

[0036] Also, see Figure 5 As shown, the ash discharge port 2 is matched with the filter element 9 .

[0037] In addition, see Figure 3 As shown, the filter screen 8 is provided with sliders at the upper and lower ends, and is adapted to the slide groove 7 .

[0038] The specific working principle is as follows:

[0039] When the filter device is regularly maintained, the handle 57 is rotated to drive the gear 54. Since the gear 54 is partially smooth and partially has teeth, its rotation drives the rack 53 meshing with it to move forward, thereby driving the connecting rod 51 connected to the filter screen 8 to slide in the slide groove 7. When the gear 54 rotates to the smooth part, the rack 53 loses its meshing with the gear 54 and is pulled back to its original position under the action of the spring 52, and hits the filter element 9, so that the impurities on the filter element 9 are shaken off to the ash discharge port 2 below and discharged into the ash collecting bucket 3 through the ash discharge port 2. In this way, the filter element 9 can be continuously hit by reciprocating, thereby achieving the purpose of cleaning the filter element 9; and the connecting rod 5 The filter screen 8 that drives the filter element 9 to impact the filter element 9 has a filtering mesh structure, which can further filter the liquefied petroleum gas. After collecting impurities and dust for a period of time, it is only necessary to rotate the locking rod 42, and the locking rod 42 is engaged with the locking ring 43. Therefore, the reverse rotation will make the locking ring 43 larger, thereby loosening the connection between the ash collecting bucket 3 and the ash discharge port 2, and the ash collecting bucket 3 can be removed for processing. After processing, after the ash collecting bucket 3 is connected with the ash discharge port 2, tightening the locking rod 42 can make the locking ring 43 drive the sealing ring 44 to seal and lock the connection. This effectively solves the problem that the existing liquefied petroleum gas filtering device cannot clean the filter element 9 in time.
