Description

Technical Field

[0001] The invention relates to the technical field of filter presses, in particular to a fully automatic ultra-high pressure belt-type plate-frame filter press. Background Art

[0002] The plate and frame filter press is an intermittent solid-liquid separation equipment, which is light, flexible and reliable. It is composed of filter plates and filter frames arranged to form filter chambers. Under the action of the feed pump, the feed liquid is transported to each filter chamber, and the solid and liquid are separated through the filter medium. Compared with other solid-liquid separation equipment such as centrifuges, plate and frame filter presses have the advantages of low investment, power saving, and safety. They are widely used in chemical, dye, petroleum, ceramics, medicine, food, smelting and sewage treatment in various industries.

[0003] The Chinese patent with the announcement number CN116651036B discloses a plate-and-frame filter press, comprising a frame, one end of which is transversely provided with a main hydraulic cylinder, the bottom of which is also provided with a material receiving frame, and an annular guide rail fixedly installed in the length direction of the frame. A filter press plate extended and squeezed by the main hydraulic cylinder is slidably arranged in the length direction of the frame, and ears are fixedly installed on both sides of the filter press plate by bolts to realize sliding action on the frame.

[0004] The plate-and-frame filter press can utilize the existing moving structure to unload the residue during the movement of each filter plate by providing a filter plate moving mechanism. The rolling cleaning mechanism can simultaneously clean the filter plate in the circumferential and axial directions, thereby achieving the effect of contact cleaning of the residue.

[0005] However, in actual use, the rolling cleaning mechanism of the filter press can only clean the filter cloth on one filter press plate at a time, which is inefficient.

If things go on like this for a long time, the filter holes are prone to be blocked.

One end of the main air supply pipe 302 is sealed, and the other end of the main air supply pipe 302 is connected to the air outlet of the air pump 301. A pressure sensor 3021 for measuring the pipeline pressure of the main air supply pipe 302 is fixedly installed at one end of the main air supply pipe 302. The upper end of the movable air supply pipe 304 is connected to the upper end of the movable air supply pipe 304 through the branch pipe 303. The branch pipe 303 is a hose. The top of 04 is sealed, and the wind knife 305 is slidably set inside the plate frame 501. The wind knife 305 is located between the two grid plates 502. The lower end of the movable air supply pipe 304 extends from the socket 5011 into the interior of the plate frame 501 and is connected with the air inlet of the wind knife 305. In order to ensure the sealing when the filter chamber is inflated and pressurized, a lower sealing ring 3051 is fixedly installed on the top of the wind knife 305, and an upper sealing ring 5012 is fixedly installed on the inner top of the plate frame 501. The upper sealing ring 5012 and the lower sealing ring 3051 are both set as magnetic sealing rings.

[0051] The provided clearing and slag removing mechanism 3 can not only clear the elastic filter cloth 503, but also perform secondary squeezing on the filter residue in the filter chamber, thereby further reducing the water content in the filter residue.

[0052] In this embodiment, the lifting mechanism 4 includes a gantry 402 and a support rod 403. The two ends of the bottom of the gantry 402 are respectively fixed on the first support seat 101 and the second support seat 102. Two support rods 403 are provided. The two support rods 403 are arranged in parallel. Both ends of the support rod 403 are fixedly connected by a connecting plate 404. The first support seat 101 and the second support seat 102 are fixedly installed with a lifting cylinder 401. The top of the piston rod of the lifting cylinder 401 is fixedly connected to the bottom of the corresponding connecting plate 404. The side of the gantry 402 is fixedly connected with a slide rail 4021. The support rod 4 03 is fixedly connected with a second arc-shaped slider 405 at the end thereof, and the second arc-shaped slider 405 is slidably set on the slide rail 4021. The movable air supply pipe 304 is slidably set between the two support rods 403 through a sliding member.

The ends of the two connecting rods 3042 away from the sleeve 3041 are fixedly connected with a first arc-shaped slider 3043, and the first arc-shaped slider 3043 is slidably clamped on the support rod 403.

[0053] The air pump 301 is fixedly mounted on the top of one end of the gantry 402 , and the main air supply pipe 302 is fixed on the top of the gantry 402 through a pipe seat.

[0054] Through the above-mentioned clearing and slag removal mechanism 3 and lifting mechanism 4, when in use, when it is necessary to perform secondary squeezing on the filter residue in the filter chamber, the air pump 301 is controlled to start, and the delivered gas is delivered to the plate frame 501 through the main air supply pipe 302, the branch pipe 303, the movable air supply pipe 304 and the air knife 305. At this time, the air knife 305 is located at the inner top of the plate frame 501. As the air pressure in the plate frame 501 continues to rise, the elastic filter cloth 503 is deformed to a certain extent, thereby performing secondary squeezing on the filter residue in the filter chamber to further reduce the water content in the filter residue. Then, the drainage solenoid valve 507 is opened to drain the water in the plate frame 501. The water is discharged, and then the piston rod of the hydraulic cylinder 201 is controlled to retract. At this time, the filter plate 5 is quickly separated under the pull of the pressure plate 202 and the pull rope 9, and the large pieces of filter residue on the elastic filter cloth 503 fall off. At this time, the air pump 301 is controlled to start, and gas is delivered to the inside of the plate frame 501 again. At the same time, the piston rod of the lifting cylinder 401 is controlled to retract, thereby driving the wind knife 305 to move downward, and then the filter residue on the elastic filter cloth 503 is cleaned, and the filter residue blocking the filter holes of the elastic filter cloth 503 is cleaned. After cleaning, the piston rod of the lifting cylinder 401 is controlled to extend, the wind knife 305 is reset, and the air pump 301 is turned off at the same time.

[0055] In this embodiment, the conveying mechanism 6 is arranged below the filter plate 5, and the conveying mechanism 6 includes a conveying frame 601, which is fixed at the lower end of the frame 1. A conveying belt 602 is rotatably installed on the conveying frame 601, and a conveying motor 603 for driving the conveying belt 602 to rotate is fixedly installed on the conveying frame 601. Guide plates 604 for preventing filter residue from splashing are fixedly installed on both sides of the lower end of the frame 1. The filter residue can be conveyed by the set conveying mechanism 6.

[0056] In this embodiment, a controller is installed in the control box 7, and the solenoid valve for controlling the extension and retraction of the piston rod of the hydraulic cylinder 201, the solenoid valve for controlling the extension and retraction of the piston rod of the lifting cylinder 401, the drainage solenoid valve 507, the air pump 301 and the conveying motor 603 are all controlled by the controller, and the pressure sensor 3021 is electrically connected to the signal input terminal of the controller. Through the provided controller, the fully automatic operation of the filter press can be realized.

[0057] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in the actual process is described in detail below.

[0058] Working Principle: The operation steps of this fully automatic ultra-high pressure belt plate and frame filter press specifically include the following steps:

[0059] S1, the controller controls the piston rod of the hydraulic cylinder 201 to extend, squeeze the filter plate 5, and form a filter chamber between two adjacent filter plates 5, and then the sewage enters the filter chamber through the sewage pipe and the sewage conveying pipe 504, and the sewage entering the filter chamber is filtered by the elastic filter cloth 503, and the filter residue is intercepted on the elastic filter cloth 503, and the filtered water is discharged through the drain port 5013 and the drain solenoid valve 507;

[0060] S2. After a period of time, the sewage pipe stops conveying sewage, and the controller controls the drainage solenoid valve 507 to close, and then controls the air pump 301 to start. The conveyed gas is conveyed to the plate frame 501 through the main air supply pipe 302, the branch pipe 303, the movable air supply pipe 304 and the wind knife 305. At this time, the wind knife 305 is located at the inner top of the plate frame 501. As the air pressure in the plate frame 501 continues to rise, the elastic filter cloth 503 is deformed to a certain extent, and then the filter residue in the filter chamber is squeezed for a second time to further reduce the water content in the filter residue. When the pressure sensor 3021 detects that the pressure in the main air supply pipe 302 reaches a preset value, the controller controls the air pump 301 to close, and then opens the drainage solenoid valve 507 to discharge the water in the plate frame 501.

[0061] S3, then the controller controls the piston rod of the hydraulic cylinder 201 to retract, at this time, the filter plate 5 is quickly separated under the pull of the pressure plate 202 and the pull rope 9, and the large pieces of filter residue on the elastic filter cloth 503 fall onto the conveyor belt 602. At this time, the air pump 301 is controlled to start, and gas is transported to the inside of the plate frame 501 again, and at the same time, the piston rod of the lifting cylinder 401 is controlled to retract, thereby driving the wind knife 305 to move downward, and then the filter residue on the elastic filter cloth 503 is cleaned, and the filter residue blocked on the filter holes of the elastic filter cloth 503 is cleaned. After the cleaning is completed, the piston rod of the lifting cylinder 401 is controlled to extend, the wind knife 305 is reset, and the air pump 301 is turned off at the same time;

[0062] S4, then control the conveying motor 603 to start, and the conveying motor 603 conveys the filter residue dropped onto the conveyor belt 602 to the filter residue collection area for centralized processing.
