Description

Technical Field

[0001] This utility model relates to the field of multi-layer waste acid filtration technology, specifically to a multi-layer waste acid filtration device. Background Technology

[0002] Waste acid is acidic waste liquid generated after industrial production or laboratory use. It mainly includes waste sulfuric acid and waste hydrochloric acid, among which waste sulfuric acid is the most common. It mainly comes from chemical reactions such as nitration, esterification, and sulfonation of organic matter, as well as industrial processes such as titanium dioxide production and steel pickling. Waste acid needs to be filtered before it is disposed of.

[0003] Existing technologies lack a multi-layer filtration structure to prevent leakage of waste acid, resulting in most waste acid filtration processes using only single-layer or single-layer multi-group filtration, which is not only inefficient but also prone to overflow or leakage accidents. If multiple filter cartridges are used, waste acid is very likely to seep out and leak when the filter cartridges are disassembled for cleaning. Based on the shortcomings of existing technologies, this utility model designs a multi-layer waste acid filtration device. Utility Model Content

[0006] The multi-layer filtration mechanism includes a filter cylinder, a filter plate, a matching slot, a matching insert plate, a connecting bolt, a connector, a nut, and a connecting sealing ring. Three sets of filter cylinders are arranged inside the seepage-proof cylinder. The filter plate is fixedly connected to the inner wall of the filter cylinder.

The connecting bolt is fixedly connected to the outer wall of the bottom of the filter cylinder. The connector is fixedly connected to the outer wall of the top of the filter cylinder. The nut is threadedly connected to the connector. The connecting sealing ring is arranged between the matching insert plate and the matching slot.

[0007] As a preferred embodiment of this utility model, the sealing mechanism includes a first tube cover, a flushing valve tube, a double-groove frame, a nylon hinge, a sealing plate, a connecting plate, an inclined plate, a spring, and a second tube cover. The first tube cover is fixedly connected to the top of the multi-layer filtration mechanism. The double-groove frame is fixedly connected to the inner wall of the first tube cover. The nylon hinge is fixedly connected to the upper surface of the double-groove frame. The sealing plate is rotatably closed onto the upper surface of the double-groove frame. The connecting plate is fixedly connected to the upper surface of the double-groove frame. The inclined plate is fixedly connected to the top of the connecting plate. The spring is fixedly disposed between the inclined plate and the sealing plate. The second tube cover is disposed at the bottom of the multi-layer filtration mechanism. The flushing valve tube is fixedly connected to the side wall of the second tube cover.

[0008] As a preferred embodiment of this utility model, the bottom end of the seepage-proof cylinder is fixedly connected to a support leg, the top end of the seepage-proof cylinder is covered with a sealing top cover, a liquid outlet pipe is fixedly connected through the sealing top cover, a liquid outlet sealing ring is fixedly connected to the inner wall of the bottom end of the liquid outlet pipe, a liquid inlet pipe is fixedly connected through the bottom end of the seepage-proof cylinder, a liquid inlet sealing ring is fixedly connected to the inner wall of the liquid inlet pipe, and a cover plate sealing ring is provided between the seepage-proof cylinder and the sealing top cover.

[0009] As a preferred embodiment of this utility model, the insert plate at the bottom of the upper filter cylinder is inserted into the slot at the top of the lower filter cylinder, and the connecting bolt at the bottom of the upper filter cylinder is inserted into the connector at the bottom of the lower filter cylinder.

[0010] As a preferred technical solution of this utility model, the slot at the top of the uppermost filter cylinder is inserted into the first tube cover, the slot plate at the bottom of the lowermost filter cylinder is inserted into the second tube cover, the connecting bolt is also provided on the first tube cover, and the connector is also provided on the second tube cover.

[0011] As a preferred embodiment of this utility model, the top end of the first tube cover is inserted into the liquid outlet pipe and the liquid outlet sealing ring, and the bottom end of the second tube cover is also inserted into the liquid inlet pipe and the liquid inlet sealing ring.

[0013] As a preferred embodiment of this utility model, the waste acid filtration flow direction of the multi-layer filtration mechanism is from bottom to top.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This multi-layer waste acid filtration device connects the liquid delivery pipe to the inlet pipe and the liquid outlet pipe to the outlet pipe. Waste acid is delivered to the second pipe cover via the liquid delivery pipe and the inlet pipe. At this time, the waste acid flowing from bottom to top lifts the sealing plate and enters the multi-layer filtration mechanism from the double tank frame. The multi-layer filtration mechanism performs multi-stage filtration. The waste acid after multi-stage filtration lifts the sealing plate in the top first pipe cover and enters the outlet pipe for discharge and collection. This device facilitates multi-stage filtration of waste acid.

[0016] 2. This multi-layer waste acid filtration device stops supplying liquid to the multi-layer filtration mechanism via external equipment. The sealing plates inside the first and second pipe covers are flipped down and closed onto the double-slot frame by nylon hinges under the push of springs, preventing the waste acid inside the multi-layer filtration mechanism from flowing out on its own and allowing it to be stored inside the multi-layer filtration mechanism. At this time, the sealed top cover is opened and the multi-layer filtration mechanism is removed from the anti-seepage cylinder. Then, the cleaning water pipe is connected to the flushing valve pipe, and the flushing valve pipe valve and the cleaning water pipe valve are opened, allowing the cleaning water to enter the multi-layer filtration mechanism from the flushing valve pipe, flushing out and collecting the waste acid inside the multi-layer filtration mechanism. Finally, the multiple filter cylinders are disassembled, cleaned, inspected, and reassembled using connecting bolts, connectors, and nuts. This device facilitates the prevention of waste acid leakage during the disassembly and cleaning of the multi-layer filtration mechanism. Attached Figure Description

The waste acid filtration flow direction of the multi-layer filtration mechanism 2 is from bottom to top.

[0026] By setting up filter cartridges 201 and filter plates 202, multi-layer filtration of waste acid is facilitated.

By setting up connecting bolts 205, connectors 206 and nuts 207, the stability of multiple sets of filter cartridges 201 after connection is improved.

[0027] Please see Figure 5 The sealing mechanism 3 includes a first tube cover 301, a flushing valve pipe 302, a double-slot frame 303, a nylon hinge 304, a sealing plate 305, a connecting plate 306, an inclined plate 307, a spring 308, and a second tube cover 309. The first tube cover 301 is fixedly connected to the top of the multi-layer filter mechanism 2. The double-slot frame 303 is fixedly connected to the inner wall of the first tube cover 301. The nylon hinge 304 is fixedly connected to the upper surface of the double-slot frame 303. The sealing plate 305 is rotatably closed onto the upper surface of the double-slot frame 303. The connecting plate 306 is fixedly connected to the upper surface of the double-slot frame 303. The inclined plate 307 is fixedly connected to the second tube cover 309. At the top of the connecting plate 306, the spring 308 is fixedly installed between the inclined plate 307 and the sealing plate 305. The second tube cover 309 is installed at the bottom of the multi-layer filter mechanism 2. The flushing valve pipe 302 is fixedly connected to the side wall of the second tube cover 309. The top of the first tube cover 301 is inserted into the liquid outlet pipe 103 and the liquid outlet sealing ring 104. The bottom of the second tube cover 309 is also inserted into the liquid inlet pipe 105 and the liquid inlet sealing ring 106. The double groove frame 303, the nylon hinge 304, the sealing plate 305, the connecting plate 306, the inclined plate 307 and the spring 308 are also installed in the second tube cover 309.

[0028] By setting a first pipe cover 301 and a second pipe cover 309, and connecting the first pipe cover 301 and the second pipe cover 309 to the multi-layer filter mechanism 2, the outlet pipe 103 and the inlet pipe 105 respectively, the upper and lower ends of the multi-layer filter mechanism 2 can be connected to the outlet pipe 103 and the inlet pipe 105 at the upper and lower ends of the anti-seepage cylinder 1 via the first pipe cover 301 and the second pipe cover 309. This effectively prevents leakage in the anti-seepage cylinder 1 if leakage occurs during filtration after multiple filter cylinders 201 are connected, thus preventing further leakage. By setting a double-groove frame 303, a nylon hinge 304 and a sealing plate 305, the first pipe cover 301 and the second pipe cover 309 at the upper and lower ends of the multi-layer filter mechanism 2 can be quickly sealed when the liquid supply in the multi-layer filter mechanism 2 is stopped for cleaning, preventing leakage of waste liquid after disassembling the multi-layer filter mechanism 2. By setting a flushing valve pipe 302, water can be injected into the multi-layer filter mechanism 2 to discharge waste acid, thereby facilitating the disassembly and cleaning of the multi-layer filter mechanism 2.

[0029] Working principle: When the multi-layer waste acid filtration device is in use, in the initial state, the support legs 101 and the sealing top cover 102 are first set at the upper and lower ends of the seepage prevention cylinder 1. The bottom of the seepage prevention cylinder 1 and the sealing top cover 102 are respectively provided with the liquid outlet pipe 103, the liquid outlet sealing ring 104, the liquid inlet pipe 105 and the liquid inlet sealing ring 106. The multi-layer filtration mechanism 2 is inserted between the liquid outlet pipe 103 and the liquid inlet pipe 105 to facilitate multi-layer filtration of waste acid. The upper and lower ends of the multi-layer filtration mechanism 2 are provided with the connection between the liquid outlet pipe 103 and the liquid inlet pipe 105 to prevent the waste acid in the multi-layer filtration mechanism 2 from leaking during the cleaning process after the injection of waste acid stops.

[0030] When multi-stage filtration of waste acid is required, first connect the liquid delivery pipe to the liquid inlet pipe 105 and the liquid outlet pipe to the liquid outlet pipe 103. Use the liquid delivery pipe and the liquid inlet pipe 105 to send the waste acid into the second pipe cover 309. At this time, the waste acid flowing from bottom to top will lift the sealing plate 305 and enter the multi-stage filtration mechanism 2 from the double tank frame 303. The multi-stage filtration mechanism 2 will perform multi-stage filtration. The waste acid after multi-stage filtration will lift the sealing plate 305 in the top first pipe cover 301 and enter the liquid outlet pipe 103 for discharge and collection. This device is convenient for multi-stage filtration of waste acid.

[0031] When it is necessary to prevent waste acid leakage during the disassembly and cleaning of the multi-layer filter mechanism 2, the external equipment first stops supplying liquid to the multi-layer filter mechanism 2. Under the push of the spring 308, the sealing plate 305 inside the first pipe cover 301 and the second pipe cover 309 flips down and covers the double-slot frame 303 to seal it, so that the waste acid in the multi-layer filter mechanism 2 will not flow by itself and can be stored in the multi-layer filter mechanism 2. At this time, open the sealing top cover 102 and take the multi-layer filter mechanism 2 out of the anti-seepage cylinder 1. Then connect the cleaning water pipe to the flushing valve pipe 302 and open the valve of the flushing valve pipe 302 and the cleaning water pipe valve to allow the cleaning water to enter the multi-layer filter mechanism 2 from the flushing valve pipe 302 to flush out and collect the waste acid in the multi-layer filter mechanism 2. Finally, use the connecting bolt 205, the connector 206 and the nut 207 to disassemble, clean, repair and reassemble the multiple filter cylinders 201. This device is convenient to prevent waste acid leakage during the disassembly and cleaning of the multi-layer filter mechanism 2.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
