Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a high-efficiency bag filter. Background Technology

[0002] Bag filters are used in petrochemical and gas refineries to recycle and treat waste acid and industrial wastewater. A bag filter is a pressure filtration device, mainly composed of a filter cylinder, filter cylinder cover and quick-opening mechanism, mesh cylinder, and filter bags. The filter bags are installed inside the mesh cylinder. Waste liquid flows into the filter bags through the inlet pipe on the side of the cylinder. The waste liquid permeates through the filter bags of the required fineness to obtain qualified filtrate, while impurity particles are intercepted by the filter bags.

[0003] Bag filters are mainly divided into single-bag filters and multi-bag filters. Single-bag filters have advantages such as simple structure and convenient maintenance, but their disadvantages include a small filtration area and severe impact on filtration efficiency when the filter bags become clogged. Multi-bag filters can solve the above-mentioned shortcomings of single-bag filters. However, the filter inlets of multi-bag filters are generally located at the top of the cylinder, requiring a platform to receive the waste liquid. Therefore, when waste liquid is flushed into the filter bags from the side or bottom of the cylinder, it will remain on the platform. This makes subsequent waste liquid cleaning work more cumbersome (industrial waste liquid is acidic and requires cleaning), increasing the labor intensity of workers. At the same time, with the filter inlets of multi-bag filters located at the top of the cylinder, it is difficult to form a retention area for waste liquid filtration. When the filter bags become clogged or the amount of waste liquid entering and the amount of filtration are unbalanced, it will affect the entry of waste liquid, affect the continuity of waste liquid recycling operations, and ultimately affect the continuity of industrial production. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a high-efficiency bag filter. By setting a flow-guiding cone and a guide plate, the waste liquid is directed to flow into the filter bag, preventing the waste liquid from stagnating on the platform holding the mesh cylinder. This solves the problem that when the filter bag is clogged or the amount of waste liquid entering and the amount of filtration are unbalanced, it will affect the entry of waste liquid, the continuity of waste liquid recycling operations, and ultimately the continuity of industrial production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency bag filter, comprising a cylindrical body and supporting legs, wherein the top of the cylindrical body is provided with a cover, and the cover is connected to a handwheel rocker arm lifting mechanism for opening and closing the cover; the cylindrical body is provided with an inlet pipe and an outlet pipe, and a partition is provided below the opening of the cylindrical body, the partition dividing the inner cavity of the cylindrical body into an upper cavity and a lower cavity, and several filter ports are evenly distributed around the partition, each filter port being equipped with a filter component, and an inlet pipe outlet is provided on the partition corresponding to the position of the inlet pipe, the inlet pipe being connected to the upper cavity, and the outlet pipe being connected to the lower cavity, and a flow guiding component is also provided above the partition for guiding waste liquid into the filter port.

[0006] Furthermore, the filter component includes a mesh cylinder and a filter bag disposed inside the mesh cylinder; the filtrate flows to the filter port and finally into the filter bag.

[0007] Furthermore, the flow guiding component includes a flow guiding cone disposed in the middle part of the partition and several guide plates with inclined surfaces facing the filter port. The guide plates are disposed between the inner wall of the upper cavity and the flow guiding cone. Waste liquid flows into the upper cavity from the inlet pipe, and under the action of the flow guiding cone and the guide plates, the waste liquid flows to the filter port and finally flows into the filter bag.

[0008] Furthermore, the guide plate is designed with a herringbone shape.

[0009] Furthermore, the handwheel rocker arm lifting mechanism includes a handwheel, a cover-opening bearing, and a rocker arm. One end of the rocker arm is located on the side wall of the cylinder, and the cover-opening bearing is located at the other end of the rocker arm. The handwheel is connected to the cover-opening bearing, and the cover-opening bearing is controlled by adjusting the handwheel. When the handwheel rotates forward, the cover-opening bearing moves downward, allowing the cylinder cover to close onto the cylinder, and vice versa. The rocker arm helps the cylinder cover move from directly above the cylinder to the upper side of the cylinder, making it easier for the user to remove the filter bag installed in the inner cavity of the cylinder.

[0010] Furthermore, the handwheel rocker arm lifting mechanism also includes a rocker arm support, which is located on the side wall of the cylinder near the top, and the end of the rocker arm away from the cover bearing is connected to the rocker arm support.

[0011] Furthermore, a locking screw is provided around the upper edge of the cylinder body to lock the cylinder cover onto the cylinder body; a latch is provided on the edge of the cylinder cover at the position corresponding to the locking screw, which cooperates with the locking screw. The locking screw and the latch cooperate to form a closed space between the cylinder body and the cylinder cover, which facilitates the filtration of waste liquid.

[0012] Furthermore, the cap is a dome-shaped cap.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention, by setting a guide cone and a guide plate, directs the waste liquid to flow into the filter bag, preventing the waste liquid from stagnating on the platform holding the mesh cylinder. This solves the problem that when the filter bag is clogged or the amount of waste liquid entering is unbalanced with the amount of filtration, it will affect the entry of waste liquid, the continuity of waste liquid recycling operations, and ultimately the continuity of industrial production.

[0021] like Figure 1-4As shown, a high-efficiency bag filter includes a cylindrical body 1 and a supporting frame 2. The top of the cylindrical body 1 is provided with a dome-shaped cover 7. The cover 7 is connected to a handwheel-rocker lifting mechanism for opening and closing the cover 7. The handwheel-rocker lifting mechanism includes a handwheel 9, a cover-opening bearing 8, and a rocker arm 10. One end of the rocker arm 10 is located on the side wall of the cylindrical body 1, and the cover-opening bearing 8 is located at the other end of the rocker arm 10. The handwheel 9 is connected to the cover-opening bearing 8, and adjusting the handwheel 9 controls the opening of the cover. Bearing 8; when the handwheel 9 rotates clockwise, the cover-opening bearing 8 moves downward, allowing the cover 7 to close onto the cylinder 1, and vice versa; the rocker arm 10 helps the cover 7 move from directly above the cylinder 1 to the upper side of the cylinder 1, making it easier for the user to remove the filter bag 13 installed in the inner cavity of the cylinder 1; the handwheel rocker arm lifting mechanism also includes a rocker arm support 11, which is located on the side wall of the cylinder 1 near the top, and the end of the rocker arm 10 away from the cover-opening bearing 8 is connected to the rocker arm support 11; the cylinder 1 is provided with a liquid inlet pipe 4. Along with the liquid outlet pipe 3, a partition 14 is provided below the opening of the cylinder 1. The partition 14 divides the inner cavity of the cylinder 1 into an upper cavity 15 and a lower cavity 16. Several filter ports are evenly distributed around the partition 14, and a filter component is installed on each filter port. The filter component includes a mesh cylinder 12 and a filter bag 13 disposed inside the mesh cylinder 12. An inlet pipe outlet 19 is opened on the partition 14 corresponding to the position of the liquid inlet pipe 4. The liquid inlet pipe 4 is connected to the upper cavity 15, and the liquid outlet pipe 3 is connected to the lower cavity 16. The partition 14 is connected to the filter port. Above the partition 14, there is a flow guiding component for guiding the waste liquid into the filter port. The flow guiding component includes a flow guiding cone 17 set in the middle part of the partition 14 and several guide plates 18 with inclined surfaces facing the filter port. The guide plates 18 are set in a herringbone structure. The guide plates 18 are set between the inner wall of the upper cavity 15 and the flow guiding cone 17. The waste liquid flows into the upper cavity 15 from the inlet pipe 4. Under the action of the flow guiding cone 17 and the guide plates 18, the waste liquid flows to the filter port and finally flows into the filter bag 13.

[0022] Furthermore, a locking screw 5 is provided around the upper edge of the cylinder 1. The locking screw 5 is used to lock the cylinder cover 7 onto the cylinder 1. A latch 6 is provided on the edge of the cylinder cover 7 at the position corresponding to the locking screw 5. The locking screw 5 and the latch 6 work together to form a closed space between the cylinder 1 and the cylinder cover 7, which facilitates the filtration of waste liquid.

[0023] The working principle and usage process of this utility model are as follows: Figure 1-4As shown, the filter bag 13 is fitted into the mesh cylinder 12, and the cylinder cover 7 is locked onto the cylinder body 1 by the cooperation of the locking screw 5 and the buckle 6. When the operation starts, the waste liquid flows in from the inlet pipe 4 and flows out from the outlet pipe 19. Under the guidance of the dome-shaped cylinder cover 7, the guide cone 17 and the guide plate 18, the waste liquid flows to the filter port and finally flows into the filter bag 13, avoiding the waste liquid from stagnating in the upper cavity 15. Finally, the solid impurities in the waste liquid remain in the filter bag 13. The filtered waste liquid is discharged through the outlet pipe 3 in the lower cavity 16. This fully filters the waste liquid and avoids the waste liquid from stagnating. It solves the problem that when the filter bag is blocked or the amount of waste liquid entering and the amount of filtration are unbalanced, it will affect the entry of waste liquid, affect the continuity of waste liquid recycling operation, and ultimately affect the continuity of industrial production.
