Description

Technical Field

[0001] This utility model belongs to the field of steel slag wastewater treatment technology, and in particular relates to a steel slag wastewater treatment filter press. Background Technology

[0002] A steel slag wastewater treatment filter press is a specialized piece of equipment used for treating steel slag wastewater during steel production. It is a type of wastewater treatment filter press, a pressure-driven solid-liquid separation device widely used in industries such as pharmaceuticals, chemicals, standard parts, metallurgy (including steel production), dyes, food, brewing, ceramics, oil refining, and environmental protection, including wastewater treatment. Based on differences in structure and working principle, wastewater treatment filter presses can be categorized into chamber filter presses, plate and frame filter presses, belt filter presses, vertical filter presses, and diaphragm filter presses, among others.

[0003] Traditional filter presses use pusher plates to stack multiple filter plates together. However, these plates may shift during movement, reducing the seal between filter chambers and causing uneven pressure distribution. This can result in some filtrate leaking out unfiltered, reducing filtration efficiency and affecting filter cake quality and yield. Therefore, we propose a steel slag wastewater treatment filter press. Utility Model Content

[0004] The purpose of this invention is to provide a steel slag wastewater treatment filter press to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a steel slag wastewater treatment filter press, comprising a filter press and a plurality of filter plates, wherein the plurality of filter plates are arranged on the filter press, and further comprising:

[0006] A support plate is fixedly connected to the filter press. The support plate has a first sliding groove that communicates with the outside. Two sliding plates are slidably connected in the first sliding groove. Two fixing blocks are fixedly connected to the top surfaces of the two sliding plates respectively.

[0007] Two first sliders are disposed in a first slide groove, and multiple transmission rods are rotatably connected between the two first sliders and two fixed blocks, respectively.

[0008] A drive assembly, located within a support plate, is used to move two first sliders.

[0009] Two fixed plates are fixedly connected to the bottom surfaces of two sliding plates respectively. Two second sliding grooves are opened on the bottom surfaces of the fixed plates. Two first sliding rods are slidably connected in the two second sliding grooves respectively. Correction plates are fixedly connected to the bottom ends of the two first sliding rods.

[0010] An adjustment component is located inside a fixed plate and is used to move the correction plate.

[0011] Based on the above structure, the second slide rail, the first slide rod, and the correction plate ensure that multiple first slide rods can move along multiple second slide rails respectively, allowing the multiple first slide rods to restrict two correction plates, so that the two correction plates can only move up and down. The drive components ensure that the user can drive the two correction plates up and down respectively through the two drive components. The first slide rail, the slide plate, and the fixed plate ensure that the two slide plates can drive the two fixed plates to move along the first slide rail, allowing the two fixed plates to drive the two correction plates to move respectively. The drive components, the first slider, and the transmission rods ensure that the user can drive the two first sliders to move away from each other or closer to each other through the drive components, allowing the two first sliders to drive the two fixed blocks to move closer to each other or further away from each other through multiple transmission rods.

[0012] In the above technical solution, the driving component further includes:

[0013] The third slide groove is formed on the top surface of the support plate. Two second sliders are slidably connected in the third slide groove, and the bottom ends of the two second sliders extend into the first slide groove and are fixed to the top surfaces of the two first sliders respectively. A bidirectional threaded rod is threaded between the two second sliders, and the bidirectional threaded rod is located in the third slide groove and rotatably connected to the third slide groove.

[0014] The first motor is fixedly connected to one side of the support plate, and the output shaft of the first motor passes through the support plate and extends into the third slide groove to be fixed to one end of the bidirectional threaded rod.

[0015] In this technical solution, it is ensured that the two second sliders can drive the two first sliders to move away from each other or closer to each other.

[0016] In the above technical solution, furthermore, the two threads on the bidirectional threaded rod have opposite directions of rotation.

[0017] In this technical solution, it is ensured that when the bidirectional threaded rod rotates, the two second sliders are acted upon by the two sections of threads with opposite directions on the bidirectional threaded rod, causing them to move away from or towards each other.

[0018] In the above technical solution, furthermore, the bottom ends of the two second sliders are slidably connected to the first groove.

[0019] In this technical solution, it is ensured that the bottom ends of the two second sliders can slide normally within the first groove.

[0020] In the above technical solution, the output shaft of the first motor is rotatably connected to the support plate.

[0021] In this technical solution, it is ensured that the output shaft of the first motor can rotate normally within the support plate.

[0022] In the above technical solution, the adjustment component further includes:

[0023] The fourth slide groove is formed inside the fixed plate and connected to the outside. A second slide rod is slidably connected inside the fourth slide groove, and the bottom end of the second slide rod is fixed to the correction plate. A one-way threaded rod is threaded inside the second slide rod, and the one-way threaded rod is located inside the fourth slide groove and rotatably connected to the fourth slide groove.

[0024] The motor slot is located inside the fixed plate and communicates with the fourth slide groove. A second motor is fixedly connected inside the motor slot, and the output shaft of the second motor extends into the fourth slide groove and is fixed to one end of the one-way threaded rod.

[0025] In this technical solution, it is ensured that the user can move the other two correction plates up and down.

[0026] In the above technical solution, the output shaft of the second motor is further rotatably connected to the fourth slide groove.

[0027] In this technical solution, it is ensured that the output shaft of the second motor can rotate normally within the fourth slide groove.

[0028] The beneficial effects of this utility model are:

[0029] This steel slag wastewater treatment filter press, through the setting of a second slide chute, a first slide rod, and a correction plate, ensures that multiple first slide rods can move along multiple second slide chutes respectively, allowing each first slide rod to restrict two correction plates, restricting their movement to vertical only. A drive assembly allows the user to move the two correction plates vertically using two separate drive components. A first slide chute, a sliding plate, and a fixed plate ensure that two sliding plates can move along the first slide chute, allowing the two fixed plates to move the two correction plates. A drive assembly, a first slider, and transmission rods allow the user to move the two first sliders closer or further apart using the drive assembly, and the two first sliders, through multiple transmission rods, can move the two fixed blocks closer or further apart. This solves the problem that when multiple filter plates shift, the sealing between the filter chambers decreases, resulting in uneven pressure distribution during filtration. This can lead to some filtrate flowing out without being fully filtered, thus reducing the filtration effect and affecting the quality and yield of the filter cake. Attached Figure Description

[0042] Example 1:

[0043] Please see Figure 1 - Figure 5 As shown, this embodiment provides a steel slag wastewater treatment filter press, including a filter press 1 and multiple filter plates 2, the multiple filter plates 2 being disposed on the filter press 1, and further including:

[0044] Support plate 3 is fixedly connected to filter press 1. A first slide groove 4 is opened in the support plate 3 to communicate with the outside. Two slide plates 5 are slidably connected in the first slide groove 4. Two fixing blocks 6 are fixedly connected to the top surface of the two slide plates 5 respectively.

[0045] Two first sliders 7 are set in the first slide groove 4, and multiple transmission rods 8 are rotatably connected between the two first sliders 7 and the two fixed blocks 6 respectively.

[0049] Example 2:

[0050] This embodiment provides a steel slag wastewater treatment filter press, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a drive component comprising:

[0051] The third slide groove 13 is opened on the top surface of the support plate 3. Two second sliders 14 are slidably connected in the third slide groove 13, and the bottom ends of the two second sliders 14 extend into the first slide groove 4 and are fixed to the top surfaces of the two first sliders 7 respectively. A bidirectional threaded rod 15 is threaded between the two second sliders 14, and the bidirectional threaded rod 15 is located in the third slide groove 13 and is rotatably connected to the third slide groove 13.

[0052] The first motor 16 is fixedly connected to one side of the support plate 3, and the output shaft of the first motor 16 passes through the support plate 3 and extends into the third slide groove 13 and is fixed to one end of the bidirectional threaded rod 15.

[0053] In use, the user starts the first motor 16, which drives the bidirectional threaded rod 15 to rotate in the third slide groove 13. This causes the two second sliders 14 to be affected by the two sections of oppositely oriented threads on the bidirectional threaded rod 15, moving them away from or closer to each other. This ensures that the two second sliders 14 can drive the two first sliders 7 to move away from or closer to each other respectively.

[0054] Example 3:

[0055] This embodiment provides a steel slag wastewater treatment filter press, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the two sections of thread on the bidirectional threaded rod 15 have opposite directions of rotation.

[0056] Specifically, when the bidirectional threaded rod 15 rotates, the two second sliders 14 are acted upon by the two sections of threads with opposite directions on the bidirectional threaded rod 15, causing them to move away from or towards each other.

[0057] Example 4:

[0058] This embodiment provides a steel slag wastewater treatment filter press, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the bottom ends of the two second sliders 14 are slidably connected to the first slide groove 4.

[0059] Specifically, it is ensured that the bottom ends of the two second sliders 14 can slide normally within the first slide groove 4.

[0060] Example 5:

[0061] This embodiment provides a steel slag wastewater treatment filter press, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the output shaft of the first motor 16 is rotatably connected to the support plate 3.

[0062] This ensures that the output shaft of the first motor 16 can rotate normally within the support plate 3.

[0063] Example 6:

[0064] This embodiment provides a steel slag wastewater treatment filter press, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including an adjustment component:

[0065] The fourth slide groove 17 is opened in the fixed plate 9 and is connected to the outside. The second slide rod 18 is slidably connected in the fourth slide groove 17, and the bottom end of the second slide rod 18 is fixed to the correction plate 12. The second slide rod 18 is threadedly connected to a one-way threaded rod 19, and the one-way threaded rod 19 is located in the fourth slide groove 17 and is rotatably connected to the fourth slide groove 17.

[0066] The motor slot 20 is opened in the fixed plate 9 and is connected to the fourth slide groove 17. The second motor 21 is fixedly connected in the motor slot 20, and the output shaft of the second motor 21 extends into the fourth slide groove 17 and is fixed to one end of the one-way threaded rod 19.

[0067] In use, the user starts the two second motors 21, and the output shafts of the two second motors 21 drive the two one-way threaded rods 19 to rotate in the two second slide rods 18. The two second slide rods 18 are respectively acted on by the threads of the two one-way threaded rods 19, and move up and down along the two fourth slide grooves 17. The two second slide rods 18 drive the two correction plates 12 to move up and down, so that the user can drive the other two correction plates 12 to move up and down.

[0068] Example 7:

[0069] This embodiment provides a steel slag wastewater treatment filter press, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the output shaft of the second motor 21 is rotatably connected to the fourth slide groove 17.

[0070] Specifically, it ensures that the output shaft of the second motor 21 can rotate normally within the fourth slide groove 17.

[0071] In use, the user starts the two second motors 21, causing their output shafts to drive the two one-way threaded rods 19 to rotate within the two second slide rods 18. This causes the two slide rods 18 to move up and down along the two fourth slide grooves 17, driven by the threads of the one-way threaded rods 19. This movement of the two slide rods 18 then drives the two alignment plates 12 to move up and down. As the alignment plates 12 move up and down, they drive multiple first slide rods 11 to move up and down along multiple second slide grooves 10. When the alignment plates 12 move down to the appropriate position, they are positioned on either side of the multiple filter plates 2. Then, the user starts the first motor 16, causing its output shaft to drive the bidirectional threaded rod 15 to rotate within the third slide groove 13. This causes the two second sliders 14 to move away from or towards each other due to the opposing threads on the bidirectional threaded rod 15. This causes the two second sliders 14 to drive the two first sliders 7 to move away from or towards each other. When the two first sliders 7 move away from each other, they will drive the two fixed blocks 6 to move closer together via multiple transmission rods 8. This will cause the two fixed blocks 6 to drive the two slide plates 5 to move closer together within the first slide groove 4. When the two slide plates 5 move closer together, they will drive the two fixed plates 9 to move closer together, which in turn will drive the two correction plates 12 to move closer together. When the two correction plates 12 move to the appropriate position, they will contact the multiple filter plates 2, ensuring that they can correct the multiple filter plates 2. This prevents the multiple filter plates 2 from shifting during the process of the push plate on the filter press 1 moving when the user starts the filter press 1. When the user needs to clean the filter press 1 after use, the user can control the two correction plates 12 to move upwards. When the two correction plates 12 move upwards to the appropriate position, they will not affect the user's cleaning of the multiple filter plates 2.

[0072] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
