Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to an online vibration self-cleaning filter for use in vacuum systems. Background Technology

[0002] In the field of gas transmission and distribution, especially in vacuum pumping, powdery substances inside the vacuum chamber are extracted with the air by the vacuum pump. Once inside the pump, the powder can cause severe damage to the pump's rotor components. In production processes involving high levels of dust, existing vacuum dust filters commonly suffer from easy clogging of the filter elements. This results in a maintenance cycle shorter than a complete production process, requiring downtime for filter element maintenance and preventing the completion of a full production cycle.

[0003] In existing patents, the applicant filed a Chinese patent application on December 13, 2023, with application number 202323410923.8, disclosing a dust filtration system for a vacuum pump. The system includes a sealed chamber, an exhaust pipe, a sealed cavity formed by the inner wall of the sealed chamber, a filter device disposed in the sealed cavity, an air storage tank disposed on the sealed chamber, an air inlet pipe disposed on the sealed chamber and communicating with the sealed cavity, and a connecting pipe disposed on the sealed chamber. The filter device includes a primary filter element, a first filter cavity formed by the inner wall of the primary filter element, a secondary filter element disposed in the first filter cavity, a second filter cavity formed by the inner wall of the secondary filter element, and a dust collection chamber located below the first filter cavity and communicating with the first filter cavity. Although the patent document shows good filtration and dust removal effects, the primary and secondary filter elements are prone to clogging after long-term use, which reduces the filtration effect and may even require shutdown for maintenance of the primary and secondary filter elements. This will affect the production efficiency of the process and increase the labor cost and intensity of maintaining the primary and secondary filter elements.

[0004] Therefore, the defects are very obvious, and a solution is urgently needed. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a vibration self-cleaning filter.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vibrating self-cleaning filter includes a filter canister, a first filter element assembly, and a second filter element assembly. The filter canister has an air inlet on one side of its bottom and an air outlet on one side of its top. A cleaning port is located at the bottom of the filter canister. The first and second filter element assemblies are arranged sequentially from bottom to top within the filter canister, positioned between the air inlet and outlet. The first filter element assembly includes a top cover, a filter screen, an elastic element, and a vibrator. A raised ring is provided on the inner wall of the filter canister. The top cover is elastically connected to the raised ring via the elastic element and is located above the raised ring. The filter screen is installed on the bottom surface of the top cover and passes through the central hole of the raised ring. The vibrator is installed inside the filter screen. A through hole is provided in the center of the top cover.

[0008] Furthermore, the cleaning port is detachably connected to a cleaning door.

[0009] Furthermore, the number of first filter elements is one or more, and the multiple first filter elements are arranged in a straight line from bottom to top.

[0010] Furthermore, the number of second filter elements is one or more, and the multiple second filter elements are arranged in a straight line from bottom to top.

[0011] Furthermore, there are multiple elastic elements arranged around the through hole.

[0012] Furthermore, a dust collection hopper is connected to the bottom of the filter tank, and the cleaning port is located at the bottom of the dust collection hopper.

[0013] Furthermore, the dust storage hopper is inverted cone shape.

[0014] Furthermore, the top port of the filter tank is detachably connected to an end cap.

[0015] Furthermore, the end cap is secured to the top of the filter tank via a locking assembly.

[0016] Furthermore, the first filter element assembly is exposed at the air intake.

[0017] The beneficial effects of this invention are as follows: In practical applications, a mixed gas carrying dust enters the filter canister through the inlet. This mixed gas passes through the first filter element assembly from the outside in, where the filter screen filters out most of the dust (e.g., large-diameter, medium-diameter, and some small-diameter dust particles). The gas then flows upward through the through-holes and undergoes secondary filtration through the second filter element assembly to form clean gas. This clean gas is then extracted from the outlet by a vacuum pump. As the amount of dust adhering to the surface of the filter screen gradually increases over time, the vibrator is controlled pneumatically via a timed control box or manually operated. The vibrator drives the filter screen to vibrate at high frequency, thereby shaking off the dust adhering to the filter screen surface and causing it to fall into the cleaning port, facilitating dust removal. Furthermore, because the top cover is elastically connected to the convex ring via an elastic element, the elastic element absorbs the vibration of the top cover following the filter screen, preventing hard impact collisions between the top cover and the convex ring and reducing noise. This application can effectively and promptly remove dust and impurities adhering to the filter element and filter screen through the vibration of the vibrator, thus effectively cleaning and maintaining the filter element and filter screen. This allows the entire filter to operate continuously for a long time, extends the maintenance cycle of the filter element assembly, greatly reduces the labor cost of frequent cleaning and maintenance of the filter element assembly, and improves the production efficiency of the process. Moreover, the cleaning of dust and impurities is convenient. Attached Figure Description

[0021] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0022] like Figure 1As shown, this utility model provides an online vibration self-cleaning filter for a vacuum system, comprising a filter canister 1, a first filter element assembly 2, and a second filter element assembly 3. The filter canister 1 has an air inlet 4 on one side of its bottom, an air outlet 5 on one side of its top, and a cleaning port 6 at its bottom. The first filter element assembly 2 and the second filter element assembly 3 are sequentially arranged inside the filter canister 1 from bottom to top, located between the air inlet 4 and the air outlet 5. The filter canister 1 includes a top cover 7, a filter element 8, an elastic element 9, and a vibrator 10. The inner wall of the filter canister 1 is provided with a convex ring 15. The top cover 7 is elastically connected to the convex ring 15 via the elastic element 9. The top cover 7 is located above the convex ring 15. The filter element 8 is installed on the bottom surface of the top cover 7 and passes through the central hole of the convex ring 15. The vibrator 10 is installed inside the filter element 8. A through hole 11 is opened in the middle of the top cover 7. Specifically, the air outlet 5 is connected to a vacuum pump, the vibrator 10 is electrically connected to a control box, and the air inlet 4 and the air outlet 5 are located on both sides of the filter canister 1, respectively.

[0023] In practical applications, a mixed gas carrying dust enters the filter canister 1 through the inlet 4. This mixed gas passes through the first filter element assembly 2 from the outside in. The filter element screen 8 filters out most of the dust (e.g., large-diameter, medium-diameter, and some small-diameter dust particles). The gas flows upward through the through-hole 11 and then undergoes secondary filtration through the second filter element assembly 3 to form clean gas. This clean gas is then extracted from the outlet 5 by a vacuum pump. As the amount of dust adhering to the surface of the filter element screen 8 gradually increases over time, the vibrator 10 is pneumatically controlled via a timer or manually operated control box. The vibrator 10 drives the filter element screen 8 to vibrate at high frequency, thereby dislodging the dust adhering to the surface of the filter element screen 8 and causing it to fall into the cleaning port 6, allowing the dust to be discharged from the cleaning port 6 for easy cleaning. Since the top cover 7 is elastically connected to the convex ring 15 via the elastic element 9, the elastic element 9 absorbs the vibration of the top cover 7 following the filter element 8, preventing the top cover 7 from having a hard impact collision with the convex ring 15 and reducing noise. This application can effectively and promptly remove dust and impurities attached to the filter element 8 from the filter element 8 through the vibration of the vibrator 10, effectively cleaning and maintaining the filter element 8. This allows the entire filter to operate continuously for a long time, extending the maintenance cycle of the filter element assembly, greatly reducing the labor cost of frequent cleaning and maintenance of the filter element assembly, improving the production efficiency of the process, and making the cleaning of dust and impurities convenient.

[0024] Specifically, a wire passage hole is provided on the side wall of the filter tank 1, through which the wire of the vibrator 10 passes. A sealing ring is provided at the wire passage hole to seal the connection between the wire and the inner wall of the wire passage hole. This structural design facilitates the electrical connection between the vibrator 10 and the control box or power supply, and provides a good sealing effect to prevent dust leakage.

[0025] Specifically, a dust cover is installed at the wire hole to effectively prevent dust leakage.

[0026] In this embodiment, the cleaning port 6 is detachably connected to a cleaning door. Under normal conditions, the cleaning door closes the cleaning port 6, and dust can accumulate at the bottom of the filter tank 1. When it is necessary to clean the accumulated dust, the cleaning door is opened, and the dust can be discharged from the cleaning port 6, which facilitates dust cleaning.

[0027] In this embodiment, there are one or more first filter element assemblies 2, which are arranged in a straight line from bottom to top. This structural design further improves the filtration effect.

[0028] In this embodiment, there are one or more second filter element assemblies 3, which are arranged in a straight line from bottom to top. This structural design further improves the filtration effect.

[0029] Specifically, the structure of the second filter element assembly 3 can be the same as that of the first filter element assembly 2.

[0030] In this embodiment, there are multiple elastic elements 9, which are arranged in a ring array around the through hole 11; specifically, the elastic elements 9 can be springs.

[0031] In this embodiment, a dust collection hopper 12 is connected to the bottom of the filter tank 1, and a cleaning port 6 is located at the bottom of the dust collection hopper 12. In practical applications, dust that falls off the filter element and filter screen 8 will fall into the dust collection hopper 12. Since the cleaning door closes the cleaning port 6, the dust accumulates in the dust collection hopper 12. When it is necessary to clean the dust, the cleaning door is opened, and the dust accumulated in the dust collection hopper 12 will be discharged from the cleaning port 6.

[0032] In this embodiment, the dust hopper 12 is inverted cone shape. This structural design facilitates the discharge of dust from the dust hopper 12 through the cleaning port 6.

[0033] In this embodiment, the top port of the filter tank 1 is detachably connected to an end cap 13; in practical applications, the end cap 13 opens the top port of the filter tank 1, facilitating the disassembly, assembly, and maintenance of the first filter element assembly 2 and the second filter element assembly 3.

[0034] In this embodiment, the end cap 13 is locked to the top of the filter tank 1 via a locking assembly 14; specifically, the locking assembly 14 can be a bolt assembly. This structural design not only facilitates the disassembly and assembly of the end cap 13 and the filter tank 1, but also ensures a secure assembly between the end cap 13 and the filter tank 1.

[0035] In this embodiment, the first filter element assembly 2 is exposed at the air inlet 4. The mixed gas enters the filter canister 1 from the air inlet 4 and flows face-to-face onto the filter screen 8 of the first filter element assembly 2, which helps to improve the filtration efficiency.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
