A treatment device for chemical fiber wastewater

Abstract

This invention discloses a treatment device for chemical fiber wastewater, relating to the field of wastewater treatment, including an inlet tank; a first storage tank; a first connecting pipe; a filter; a drain tank; a connecting mechanism; and a drainage mechanism. By setting up a drainage mechanism, when the I-shaped connecting frame moves the sealing block, the piston block can block the drain outlet on one side of the inlet tank. During this process, water flow in the first connecting pipe can be drawn, allowing water from the filter below the second storage tank to pass through the second connecting pipe and the second one-way valve into the first storage tank. This prevents residual water in the filter from affecting operator operations. The filter located below the first storage tank can then be removed for replacement. When the filter is reinstalled below the first storage tank, the movement of the piston block allows water in the second storage tank to be discharged through the first one-way valve, facilitating filter replacement.

Description

Technical Field

[0001] This invention relates to the field of wastewater treatment, specifically a treatment device for chemical fiber wastewater. Background Technology

[0002] The full name of chemical fiber is chemical fiber, which refers to fibers made from natural or artificially synthesized polymers. Depending on the source of the raw materials, they can be divided into man-made fibers made from natural polymers and synthetic fibers made from synthetic polymers.

[0003] When treating wastewater from chemical fibers, various semi-permeable membranes are generally used. These membranes are typically housed in plastic shells to form filters. The filtered wastewater is then converted into purified water and concentrated water. The concentrated water is then evaporated and concentrated to form solid waste.

[0004] In typical chemical fiber wastewater treatment systems, disassembling the filter requires stopping the wastewater supply before removing and replacing it. During this process, the wastewater supply must be stopped, and a brand new filter must be installed on the system before wastewater can be injected again. This affects the efficiency of wastewater treatment. Furthermore, when disassembling the filter, some residual water inside can spill onto the workers, causing inconvenience to the equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a treatment device for chemical fiber wastewater in order to solve the problems of not being able to replace the filter without affecting the operation of the equipment and the inconvenience of absorbing the water flow in the filter.

The first positioning hole is located at the top of the I-shaped connecting frame. The first positioning pin is located on both sides of the I-shaped connecting frame. The connecting chamber is fixed to the top of the filter. The second positioning hole extends from one side of the connecting chamber to the other side of the connecting chamber. The U-shaped connecting block is located at the bottom of the first connecting pipe. The second positioning pin is fixed to the bottom of the inlet tank. The telescopic spring is located at the bottom of the inlet tank and is sleeved on the outside of the second positioning pin.

[0015] As a further embodiment of the present invention: the drainage mechanism includes a first one-way valve, a second connecting pipe, a second one-way valve, and a third one-way valve. The third one-way valve is installed on the top of the filter, the second one-way valve is fixed to the bottom of the second water storage tank, the second connecting pipe is connected to the bottom of the second one-way valve and is located outside the first connecting pipe, and the first one-way valve is located on one side of the second water storage tank.

[0016] As a further embodiment of the present invention: the first check valve and the second check valve are installed in opposite directions, and the second check valve is connected to the first connecting pipe through the second connecting pipe.

[0017] As a further embodiment of the present invention: one end of the first positioning pin has the same diameter as the second positioning hole, and a second positioning hole is also provided on one side of the U-shaped connecting block, extending to the other side of the U-shaped connecting block. A sealing gasket is provided at the position where the outer side of the connecting compartment contacts the U-shaped connecting block.

[0018] As a further embodiment of the present invention: the bottom of the second water storage tank is also provided with the filter, and there are two of each of the second and first water storage tanks, and the two second water storage tanks and the two first water storage tanks are symmetrically arranged along the transverse central axis of the filter.

[0019] As a further embodiment of the present invention: the height and thickness of the sealing block and the piston block are equal, and both the piston block and the sealing block are in contact with the inner wall of the first water storage tank.

[0020] As a further embodiment of the present invention: the two ends of the telescopic spring are respectively welded to the bottom of the water inlet chamber and the outside of the second positioning pin, the bottom of the telescopic spring is equal in diameter to the first positioning hole, and the sealing block in the first water storage chamber and the sealing block in the second water storage chamber are connected by the I-shaped connecting frame.

[0021] As a further embodiment of the present invention, the length of the connecting column is slightly larger than the diameter of one side of the water inlet chamber.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. By setting up a connecting mechanism, when replacing the filter below the first water storage tank, the new filter can be first fastened to the bottom of the second water storage tank through the U-shaped connecting block and connecting chamber. Then, the I-shaped connecting frame can be pushed. At this time, the first positioning pin on one side of the I-shaped connecting frame separates from the filter below the first water storage tank. At the same time, the piston block will block the water inlet of the water inlet at the top of the first water storage tank. This will cause the filter below the first water storage tank to lose its limit, allowing the first positioning pin on the other side of the I-shaped connecting frame to insert into the second positioning hole below the second water storage tank. At this time, the water in the water inlet will flow through the second water storage tank and the filter and be discharged from the drain tank. This achieves the effect of replacing the filter without affecting the operation of the equipment, providing convenience for the use of the equipment.

[0024] 2. By setting up a drainage mechanism, when the I-shaped connecting frame moves the sealing block, the piston block can block the drain outlet on the side of the water inlet. During this process, the water flow in the first connecting pipe can be drawn out, so that the water flow in the filter below the second water storage tank can pass through the second connecting pipe and the second one-way valve into the first water storage tank. This prevents the residual water in the filter from affecting the operator's operation. Afterwards, the filter located below the first water storage tank can be removed for replacement. When the filter is reinstalled below the first water storage tank, the movement of the piston block can discharge the water in the second water storage tank through the first one-way valve, which facilitates the replacement of the filter.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-7 In this embodiment of the invention, a treatment device for chemical fiber wastewater includes:

[0035] Inlet chamber 1;

[0036] The first water storage tank 4 is located on one side of the water inlet tank 1;

[0037] The first connecting pipe 5 is connected to the bottom of the first water storage tank 4;

[0038] Filter 3 is located at the bottom of the first connecting pipe 5;

[0039] Drainage chamber 2 is fixed to the bottom of the first water storage chamber 4 and located below the water inlet chamber 1;

[0040] The connecting mechanism 6 is located on the side of the water inlet chamber 1 away from the first water storage chamber 4 and on the inside of the first water storage chamber 4, and is used to replace the filter 3.

[0041] The drainage mechanism 7 is located on the outside of the first water storage tank 4 and is used to extract water from the inside of the filter 3.

[0042] In this embodiment, when using the equipment, wastewater from the production of chemical fibers can be discharged through the inlet tank 1, the first water storage tank 4, the filter 3, and the drain tank 2. The wastewater is filtered by the filter 3. Afterwards, the filter 3 can be replaced without affecting the operation of the equipment through the connecting mechanism 6, thus providing convenience for the use of the equipment. During the replacement of the filter 3, the water inside the filter 3 to be replaced can be extracted through the drain mechanism 7, thereby preventing the water inside the filter 3 from flowing out when the staff removes the filter 3.

[0043] Please refer to this carefully. Figure 1 , 2 3, 4, 5, 6, 7. The connecting mechanism 6 includes a second water storage tank 601, an I-beam connecting frame 602, a first positioning pin 603, a telescopic spring 604, a second positioning pin 605, a first positioning hole 606, a U-shaped connecting block 607, a piston block 608, a connecting column 609, a sealing block 610, a connecting chamber 611, and a second positioning hole 612. The second water storage tank 601 is located on the side of the inlet tank 1 away from the first water storage tank 4. The piston block 608 is located inside the first water storage tank 4. The connecting column 609 is fixed to one side of the piston block 608, and the sealing block 610 is fixed to one side of the connecting column 609. The I-beam... The I-shaped connecting bracket 602 is fixed to one side of the sealing block 610 and extends to the outside of the first water storage tank 4. The first positioning hole 606 is provided at the top of the I-shaped connecting bracket 602. The first positioning pin 603 is provided on both sides of the I-shaped connecting bracket 602. The connecting chamber 611 is fixed to the top of the filter 3. The second positioning hole 612 extends from one side of the connecting chamber 611 to the other side of the connecting chamber 611. The U-shaped connecting block 607 is provided at the bottom of the first connecting pipe 5. The second positioning pin 605 is fixed at the bottom of the water inlet tank 1. The telescopic spring 604 is provided at the bottom of the water inlet tank 1 and is sleeved on the outside of the second positioning pin 605.

[0044] In this embodiment, when replacing the filter 3 below the first water storage tank 4, the new filter 3 can first be fastened to the bottom of the second water storage tank 601 via the U-shaped connecting block 607 and the connecting chamber 611. Then, the second positioning pin 605 is pulled to separate the second positioning pin 605 from the first positioning hole 606. After that, the I-shaped connecting frame 602 can be pushed. At this time, the first positioning pin 603 on one side of the I-shaped connecting frame 602 separates from the filter 3 below the first water storage tank 4. At the same time, the piston block 608 will press against the top of the first water storage tank 4. By blocking the inlet of the water inlet chamber 1, the filter 3 below the first water storage chamber 4 is freed from its limiting position. This allows the first positioning pin 603 on the other side of the I-shaped connecting frame 602 to be inserted into the second positioning hole 612 below the second water storage chamber 601, thereby limiting the filter 3 below the second water storage chamber 601. At this time, the water in the water inlet chamber 1 will be discharged from the drain chamber 2 through the second water storage chamber 601 and the filter 3. During this process, the water inside the filter 3 that needs to be disassembled can also be extracted and discharged through the drainage mechanism 7.

[0045] Please refer to this carefully. Figure 1 , 2 6. The drainage mechanism 7 includes a first one-way valve 701, a second connecting pipe 702, a second one-way valve 703, and a third one-way valve 704. The third one-way valve 704 is installed on the top of the filter 3. The second one-way valve 703 is fixed to the bottom of the second water storage tank 601. The second connecting pipe 702 is connected to the bottom of the second one-way valve 703 and is located outside the first connecting pipe 5. The first one-way valve 701 is located on one side of the second water storage tank 601.

[0046] In this embodiment, when the I-shaped connecting frame 602 moves the sealing block 610, the piston block 608 moves along with the sealing block 610. As the piston block 608 moves towards the sealing block 610, it can block the drain outlet on one side of the water inlet chamber 1. During this process, water can be drawn from the first connecting pipe 5, allowing water from the filter 3 below the second water storage chamber 601 to pass through the second connecting pipe 702 and the second one-way valve 703 into the second water storage chamber 601. During this process, external air can be introduced into the filter 3 through the third one-way valve 704, thereby maintaining the pressure balance between the inside of the filter 3 and the outside, thus preventing the residual water in the filter 3 from affecting the operation of the staff. After that, the filter 3 located below the second water storage tank 601 can be removed for replacement. When the filter 3 is reinstalled in the second water storage tank 601, the water in the second water storage tank 601 can be discharged through the first one-way valve 701 by the movement of the piston block 608, which facilitates the replacement of the filter 3.

[0047] Please refer to this carefully. Figure 6The first check valve 701 and the second check valve 703 are installed in opposite directions. The second check valve 703 is connected to the first connecting pipe 5 through the second connecting pipe 702.

[0048] In this embodiment, by setting this structure so that the piston block 608 moves toward the sealing block 610, the water flow in the first connecting pipe 5 can be extracted, so that the water flow passes through the second connecting pipe 702 and the second one-way valve 703 and enters the second water storage tank 601. When the piston block 608 returns to its original position, the water flow in the second water storage tank 601 will be discharged to the outside of the second water storage tank 601 through the first one-way valve 701.

[0049] Please refer to this carefully. Figure 3 , 5 One end of the first positioning pin 603 has the same diameter as the second positioning hole 612. A second positioning hole 612 is also provided on one side of the U-shaped connecting block 607, extending to the other side of the U-shaped connecting block 607. A sealing gasket is provided at the position where the outer side of the connecting compartment 611 contacts the U-shaped connecting block 607.

[0050] In this embodiment, by setting this structure so that when the connecting compartment 611 is fastened to the inside of the U-shaped connecting block 607, and the second positioning hole 612 on the outside is aligned with the second positioning hole 612 on the outside of the U-shaped connecting block 607, the I-shaped connecting frame 602 is pushed. When the I-shaped connecting frame 602 moves, it will drive the first positioning pin 603 to move, so that the first positioning pin 603 is inserted into the second positioning hole 626, thereby realizing the connection between the U-shaped connecting block 607 and the connecting compartment 611, so that the water flows through the first connecting pipe 5 and enters the interior of the filter 3 for purification treatment.

[0051] Please refer to this carefully. Figure 1 The bottom of the second water storage tank 601 is also equipped with a filter 3. There are two second water storage tanks 601 and two first water storage tanks 4, and the two second water storage tanks 601 and the two first water storage tanks 4 are symmetrically arranged along the horizontal central axis of the filter 3.

[0052] In this embodiment, this structure is configured to create two flow paths in the device, thereby allowing the filter 3 to be used alternately.

[0053] Please refer to this carefully. Figure 2 , 6 7. The height and thickness of the sealing block 610 and the piston block 608 are equal, and both the piston block 608 and the sealing block 610 are in contact with the inner wall of the first water storage tank 4.

[0054] In this embodiment, this structure is used to increase the sealing between the piston block 608, the sealing block 610 and the first water storage tank 4.

[0055] Please refer to this carefully. Figure 1 , 2 The two ends of the telescopic spring 604 are welded to the bottom of the water inlet chamber 1 and the outside of the second positioning pin 605, respectively. The bottom of the telescopic spring 604 is equal in diameter to the first positioning hole 606. The sealing block 610 in the first water storage chamber 4 and the sealing block 610 in the second water storage chamber 601 are connected by an I-shaped connecting bracket 602.

[0056] In this embodiment, this structure is used to make the second positioning pin 605 engage with the first positioning hole 606 under the action of the telescopic spring 604, thereby preventing the I-shaped connecting frame 602 from moving relative to the water inlet chamber 1.

[0057] Please refer to this carefully. Figure 2 The length of the connecting column 609 is slightly larger than the diameter of one side of the water inlet chamber 1.

[0058] In this embodiment, by setting this structure, the connecting column 609 can be prevented from obstructing the water flow from the water inlet chamber 1, thereby increasing the stability of the water flow.

[0059] The working principle of this invention is as follows: When replacing the filter 3 below the first water storage tank 4, the new filter 3 can be first fastened to the bottom of the second water storage tank 601 through the U-shaped connecting block 607 and the connecting chamber 611. Then, the second positioning pin 605 is pulled to separate the second positioning pin 605 from the first positioning hole 606. After that, the I-shaped connecting frame 602 can be pushed. At this time, the first positioning pin 603 on one side of the I-shaped connecting frame 602 separates from the filter 3 below the first water storage tank 4. At the same time, the piston block 608 will block the water inlet of the water inlet chamber 1 at the top of the first water storage tank 4. In this way, the filter 3 below the first water storage tank 4 will lose its limit, and the first positioning pin 603 on the other side of the I-shaped connecting frame 602 will be inserted into the second positioning hole 612 below the second water storage tank 601, thereby limiting the filter 3 below the second water storage tank 601. At this time, the water in the water inlet chamber 1 will flow through the second water storage tank 601. 1. Filter 3 is discharged from drain chamber 2. During this process, the piston block 608 inside the first water storage chamber 4 can also move with the movement of the sealing block 610. When the piston block 608 moves towards the sealing block 610, it can block the drain outlet on the side of the water inlet chamber 1. During this process, the water flow in the first connecting pipe 5 can be extracted, so that the water flow in the filter 3 below the first water storage chamber 4 passes through the second connecting pipe 702 and the second one-way valve 703 into the second water storage chamber 601. This prevents the residual water in the filter 3 from affecting the operation of the staff. After that, the filter 3 located below the first water storage chamber 4 can be removed and replaced. When the filter 3 is reinstalled in the first water storage chamber 4, the movement of the piston block 608 can discharge the water in the second water storage chamber 601 through the first one-way valve 701, which provides convenience for the replacement of the filter 3.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
