Description

Technical Field

[0001] This utility model relates to the field of epoxy resin technology, specifically to a high-salt wastewater treatment device for epoxy resin production. Background Technology

[0002] Epoxy resin is a general term for a class of polymers containing two or more epoxy groups in their molecules. It is a condensation product of epichlorohydrin and bisphenol A or polyols. Due to the chemical reactivity of epoxy groups, it can be ring-opened by various compounds containing active hydrogen, and then cured and cross-linked to form a network structure. Therefore, it belongs to a thermosetting resin. The production process of epoxy resin generates a large amount of high-salt wastewater. If discharged directly, it will cause certain environmental pollution and may even endanger human health. Therefore, high-salt wastewater treatment equipment for epoxy resin production is needed to treat the high-salt wastewater.

[0003] Currently, most commercially available high-salt wastewater treatment equipment for epoxy resin production suffers from poor environmental performance, failing to achieve the desired wastewater treatment results. In actual operation, the filter screen is prone to clogging. Once clogging occurs, due to limitations in equipment design, disassembling and replacing the filter screen becomes extremely difficult. Consequently, the clogged filter screen cannot be replaced in time, inevitably leading to a significant reduction in filtration efficiency, which in turn severely hinders the overall efficiency of the wastewater treatment equipment, preventing it from operating efficiently. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-salt wastewater treatment device for epoxy resin production, which has the advantage of preventing filter clogging during operation and solves the problem mentioned in the background technology that filter clogging affects equipment efficiency during actual operation.

[0005] To achieve the aforementioned goal of preventing filter clogging during operation, this utility model provides the following technical solution: It includes a housing, with a stirring tank fixedly connected to the top of the housing's inner cavity. A rotating rod is rotatably connected through and through the middle of the stirring tank within the inner cavity of the housing. Evenly distributed stirring rods are fixedly connected to the outer wall of the rotating rod. Two rotating rods are rotatably connected through and through the lower part of the inner cavity of the housing. A contact block is fixedly connected to the middle of the outer wall of each of the two rotating rods. Two filter mounting frames are slidably connected through and through the lower part of the inner cavity of the housing. A collection frame is fixedly connected to the top of one filter mounting frame, and the collection frame is slidably connected through the housing. A limiting plate is slidably connected through and through the inner wall of one filter mounting frame. Evenly distributed springs are fixedly connected to the top of the limiting plate, and the other end of the springs is fixedly connected to the filter mounting frame. A filter is fixedly connected to the side of the limiting plate away from the filter mounting frame. A contact plate is fixedly connected through and through the middle of the filter, and the contact block abuts against the contact plate.

[0006] As a further embodiment of this utility model: an output box is fixedly connected to one side of the outer wall of the box, and one end of rotating rod 1 and rotating rod 2 passes through the box and rotates inside the output box. A motor is installed on one side of the output box, and the output end of the motor passes through the output box and is fixedly connected to rotating rod 1. A synchronous pulley 1 is fixedly connected to one side of the outer wall of the output box, and a synchronous pulley 2 is fixedly connected to one side of the outer wall of the output box. A synchronous belt is sleeved on the outer wall of synchronous pulley 1, and the other end of the synchronous belt is sleeved on the outer wall of synchronous pulley 2.

[0007] As a further embodiment of this utility model: an L-shaped groove is provided in the middle of one side of a filter screen mounting frame that penetrates the box body. A second spring is fixedly connected to the top of the L-shaped groove, and a limiting slide plate is fixedly connected to the bottom of the second spring. The limiting slide plate slides in the L-shaped groove, and a locking rod is slidably connected to the bottom of the limiting slide plate that penetrates the filter screen mounting frame.

[0008] As a further improvement of this utility model: a slot is provided on the side of the box away from the output box, and the slot cooperates with the locking rod.

[0009] As a further improvement of this utility model: a feed inlet is provided through one side of the top of the box, and a discharge outlet is provided through the middle of the bottom of the side of the box away from the feed inlet.

[0010] As a further improvement of this utility model, a drain valve is provided through one side of the bottom of the mixing tank.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, when the rotating rod 2 rotates, the abutting block on the rotating rod 2 also rotates flexibly. Once the abutting block touches the abutting plate, it pushes the abutting plate to move smoothly upward, thereby driving the filter screen to move up and down regularly. This process makes the filter screen vibrate continuously at high frequency, effectively preventing impurities from adhering and accumulating, eliminating the risk of clogging, and ensuring efficient and smooth wastewater filtration at all times.

[0013] 2. In this utility model, when it is necessary to disassemble and replace the filter screen, the operator only needs to put his hand into the L-shaped groove and slide the limiting slide plate upward. During the upward sliding of the limiting slide plate, the spring will be compressed, and at the same time, the limiting slide plate will drive the locking rod to move upward until the locking rod separates from the locking groove. At this time, the filter screen mounting frame is pulled backward to separate it from the box, and the filter screen can be replaced. In addition, while replacing the filter screen, the waste material left in the collection frame after filtration can also be cleaned to ensure the continuous and efficient operation of the equipment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5In this embodiment of the invention, a housing 1 is included. A stirring tank 2 is fixedly connected to the top of the inner cavity of the housing 1. A rotating rod 3 is rotatably connected through the middle of the stirring tank 2 within the inner cavity of the housing 1. Evenly distributed stirring rods 4 are fixedly connected to the outer wall of the rotating rod 3. High-salt wastewater generated during epoxy resin production, and the treatment liquid used to treat this wastewater, are injected into the housing 1 through the inlet 22. After entering the housing 1, the wastewater first flows into the stirring tank 2. At this time, the motor 21 is turned on, driving the rotating rod 3 to rotate, which in turn causes the stirring rods 4 mounted on the rotating rod 3 to rotate accordingly. Under the continuous stirring of the stirring rods 4, the high-salt wastewater and the treatment liquid in the stirring tank 2 are fully mixed, greatly accelerating the treatment process of the high-salt wastewater and improving the treatment effect. The lower part of the inner cavity of the housing 1 is rotatably connected through... There are two rotating rods 9, and abutment blocks 10 are fixedly connected to the middle of the outer wall of each of the two rotating rods 9. Two filter screen mounting frames 11 are slidably connected through the lower part of the inner cavity of the box body 1. A collection frame 15 is fixedly connected to the top of one filter screen mounting frame 11, and the collection frame 15 is slidably connected through the box body 1. A limit plate 12 is slidably connected through the inner wall of one filter screen mounting frame 11. A uniformly distributed spring 13 is fixedly connected to the top of the limit plate 12, and the other end of the spring 13 is fixedly connected to the filter screen mounting frame 11. A filter screen 14 is fixedly connected to the side of the limit plate 12 away from the filter screen mounting frame 11. Two layers of filter screen 14 are provided inside, the upper layer is a primary filter screen, and the lower layer is a high-efficiency filter screen. Abutment plate 25 is fixedly connected through the middle of the filter screen 14, and abutment blocks 10 abut against abutment plate 25.An output box 5 is fixedly connected to one side of the outer wall of the housing 1. One end of the rotating rod 1 3 and the rotating rod 2 9 pass through the housing 1 and rotate inside the output box 5. A motor 21 is installed on one side of the output box 5, and the output end of the motor 21 passes through the output box 5 and is fixedly connected to the rotating rod 1 3. A synchronous pulley 1 6 is fixedly connected to the rotating rod 1 3 on one side of the outer wall of the output box 5, and a synchronous pulley 2 7 is fixedly connected to the rotating rod 2 9 on one side of the outer wall of the output box 5. A synchronous belt 8 is fitted on the outer wall of the synchronous pulley 1 6, and the other end of the synchronous belt 8 is fitted on the outer wall of the synchronous pulley 2 7. The mixed liquid will pass through the upper and lower filter screens 14. At the same time, the rotating rod 1 3 drives the synchronous pulley 1 6 to rotate, and the synchronous pulley 1 6 drives the synchronous pulley 2 7 to rotate through the synchronous belt 8, thereby driving the output box 1 5. When the rotating rod 29 rotates, the abutment block 10 mounted on it also rotates. When the abutment block 10 rotates to contact the abutment plate 25, it pushes the abutment plate 25 to move upward, thereby causing the filter screen 14 to move upward. During this process, the limiting plate 12 slides upward within the filter screen mounting frame 11, causing the spring 13 to be stretched. When the abutment block 10 continues to move forward with the rotation of the rotating rod 29 and disengages from the contact with the abutment plate 25, the stretched spring 13 releases its elastic force, causing the limiting plate 12 to move downward, and at the same time causing the filter screen 14 to reset. This cycle repeats, and the abutment block 10 continuously contacts and disengages from the abutment plate 25, causing the filter screen 14 to vibrate continuously, effectively avoiding the clogging problem caused by long-term use.

[0022] A filter mounting frame 11 has an L-shaped groove 16 extending through the middle of one side of the housing 1. A spring 17 is fixedly connected to the top of the L-shaped groove 16, and a limiting slide plate 18 is fixedly connected to the bottom of the spring 17. The limiting slide plate 18 slides within the L-shaped groove 16, and the bottom of the limiting slide plate 18 extends through the filter mounting frame 11 and is slidably connected to a locking rod 19. A slot 20 is provided on the side of the housing 1 away from the output box 5, and the slot 20 cooperates with the locking rod 19. If the filter 14 needs to be disassembled and replaced, the operator only needs to put their hand into the L-shaped groove 16 and press the limiting slide plate 18 upwards. During the upward sliding process of the limiting slide plate 18... In the middle, spring 17 will be compressed, and at the same time, the limiting slide plate 18 will drive the locking rod 19 to move upward until the locking rod 19 separates from the locking groove 20. At this time, the filter screen mounting frame 11 is pulled backward to separate it from the box 1, so that the filter screen 14 can be replaced. In addition, while replacing the filter screen 14, the waste material left after filtration in the collection frame 15 can also be cleaned to ensure the continuous and efficient operation of the equipment. The top side of the box 1 is provided with a feed inlet 22, and the bottom middle of the side of the box 1 away from the feed inlet 22 is provided with a discharge outlet 23. The bottom side of the mixing tank 2 is provided with a drain valve 24.

[0023] The working principle of this utility model is as follows: the high-salt wastewater generated during the epoxy resin production process, and the treatment liquid used to treat this wastewater, are injected into the tank 1 through the feed inlet 22. After entering the tank 1, the wastewater first flows into the mixing tank 2. At this time, the motor 21 is turned on, and the motor 21 drives the rotating rod 3 to rotate, which in turn causes the stirring rod 4 installed on the rotating rod 3 to rotate. Under the continuous stirring of the stirring rod 4, the high-salt wastewater and the treatment liquid in the mixing tank 2 are fully mixed, which greatly accelerates the treatment process of the high-salt wastewater and improves the treatment effect.

[0024] After the mixing process is completed, the drain valve 24 is opened, and the mixed liquid is drained through the upper and lower filter screens 14. At the same time, the rotating rod 3 drives the synchronous wheel 6 to rotate, and the synchronous wheel 6 drives the synchronous wheel 7 to rotate through the synchronous belt 8, which in turn drives the rotating rod 9 to rotate. When the rotating rod 9 rotates, the contact block 10 installed on it also rotates. When the contact block 10 rotates to contact the contact plate 25, it pushes the contact plate 25 to move upward, thereby causing the filter screen 14 to move upward. During this process, the limiting plate 12 will be positioned on the filter screen. The mesh installation frame 11 slides upward, stretching the spring 13. As the abutment block 10 continues to move forward with the rotation of the rotating rod 9, it disengages from the contact plate 25. The stretched spring 13 releases its elastic force, causing the limiting plate 12 to move downward, and simultaneously resetting the filter screen 14. This cycle repeats, with the abutment block 10 continuously contacting and disengaging from the contact plate 25, causing the filter screen 14 to vibrate continuously. This effectively avoids clogging caused by prolonged use. The fully filtered wastewater will eventually be discharged from the housing 1 through the discharge port 23.

[0025] If the filter screen 14 needs to be disassembled and replaced, the operator only needs to put his hand into the L-shaped groove 16 and squeeze the limiting slide plate 18 upward. During the upward sliding of the limiting slide plate 18, the spring 17 will be compressed. At the same time, the limiting slide plate 18 will drive the locking rod 19 to move upward until the locking rod 19 separates from the locking groove 20. At this time, the filter screen mounting frame 11 is pulled backward to separate it from the housing 1, and the filter screen 14 can be replaced. In addition, while replacing the filter screen 14, the waste material left in the collection frame 15 after filtration can also be cleaned to ensure the continuous and efficient operation of the equipment.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
