Description

Technical Field

[0001] This utility model relates to the field of steelmaking turbid circulating water recovery technology, and in particular to a rapid separation device for filter press residue suitable for steelmaking turbid circulating water. Background Technology

[0002] Steelmaking turbid circulating water is the circulating water containing a large amount of suspended solids, iron oxide scale, grease, metal particles, and other impurities generated during the steelmaking process, after being used for cooling equipment and rinsing steel billets. To ensure that the water quality of the turbid circulating water meets the requirements for reuse, it usually needs to be treated. Filtration is an important solid-liquid separation step, and the solid residue produced after filtration is the filter residue of steelmaking turbid circulating water.

[0003] In existing technologies, filter presses are generally used to filter turbid circulating water. During the filtration process, filter residue adheres to the filter plates. Filter presses are typically equipped with a plate-pulling trolley, which pulls the filter plates apart one by one to expose the filter residue. Then, a vibration component on the plate-pulling trolley drives the filter plates to vibrate and remove the filter residue, or it can be manually removed from the filter plates using shovels or other tools. However, the plate-pulling trolley can only move one filter plate at a time, resulting in a slow separation speed of the filter residue and affecting the recovery speed of the turbid circulating water. Therefore, an improved rapid filter residue separation device suitable for steelmaking turbid circulating water is proposed. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a rapid separation device for filter slag in steelmaking turbid circulating water, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a rapid separation device for filter slag in steelmaking turbid circulating water, comprising two bases, a main screw rotatably connected between the two bases, a main guide rod fixedly connected between the two bases, a main motor capable of driving the main screw to rotate on one side of one of the bases, two mounting plates rotatably connected to the main screw, the mounting plates being sleeved on the main guide rod; a vertical drive assembly is provided on the mounting plate, a movable seat is fixedly connected to the output end of the vertical drive assembly, a secondary screw rotatably connected between the two movable seats, the secondary screw having a plurality of sets of threaded segments with gradually increasing thread pitch sequentially opened, a secondary guide rod fixedly connected between the two mounting plates, a secondary motor capable of driving the secondary screw to rotate on one side of one of the movable seats, a plurality of sliding plates threadedly connected to the secondary screw, a drive seat fixedly connected to the bottom surface of the sliding plates, the plurality of sliding plates being respectively arranged on different threaded segments of the secondary screw, the sliding plates being sleeved on the secondary guide rod.

[0007] Preferably, in any of the above embodiments, a connecting plate is fixedly connected to the bottom of the base, and the main guide rod is located below the main lead screw.

[0008] The above technical solution provides an installation platform for the main screw, guide rod, and main motor. A connecting plate is installed on the bottom surface of the base to facilitate fixing the base to the filter press for operation. The main screw drives the mounting plate to move along its direction. The guide rod constrains the mounting plate, preventing it from rotating with the main screw.

[0009] Preferably, in any of the above solutions, the mounting plate adopts an L-shaped structure, and the auxiliary lead screw is located on one side of the main lead screw.

[0010] The above technical solution provides a mounting platform for the vertical drive components and other structures, and enables them to move. When the main motor is started, it drives the main lead screw to rotate. Under the constraint of the guide rod, the two mounting plates move horizontally synchronously, moving the vertical drive components, the moving seat, the auxiliary lead screw, and other components.

[0011] Preferably, in any of the above schemes, the auxiliary guide rod is located on one side of the auxiliary lead screw, and the number of thread turns of the several threaded segments on the auxiliary lead screw is the same.

[0012] The above technical solution employs a secondary lead screw to drive several sliding plates to move horizontally. The secondary lead screw has several threaded sections with different pitches, allowing it to drive the sliding plates to move different distances. This enables the filter plates of multiple filter presses to move at varying distances, ensuring sufficient space between adjacent filter plates for cleaning the filter residue. By controlling the number of thread turns in different threaded sections, interference between the sliding plates can be avoided.

[0013] Preferably, in any of the above solutions, the middle position of the top surface of the drive seat is fixedly connected to the sliding plate, and the drive seat drives the filter plate to move by clamping the wing plate on the side of the filter plate of the filter press.

[0014] The above technical solution is adopted: the auxiliary motor is started to drive the auxiliary lead screw to rotate. Under the constraint of the auxiliary guide rod, several sliding plates move horizontally synchronously. Since the thread pitch of several threaded sections on the auxiliary lead screw is different, the movement distance of different sliding plates is different. In this way, the filter plates of multiple filter presses can be moved to different distances.

[0015] Preferably, in any of the above embodiments, the drive base includes a base plate with an L-shaped structure, a vertical plate fixedly connected to the base plate, a push rod threadedly connected to the vertical plate, and a clamping plate rotatably connected to the inner end of the push rod.

[0016] The above technical solution involves using a drive seat to limit the position of the filter plates in the filter press and moving the filter plates under the influence of a sliding plate. By rotating a push rod, the push rod moves a clamping plate, adjusting the distance between the clamping plate and the base plate. This allows for clamping of the flanges of filter plates of different thicknesses, thereby moving the filter plates.

[0017] Preferably, as described in any of the above embodiments, a rotating ring is fixedly connected to the outer side of the clamping plate, a rotating block located within the rotating ring is fixedly connected to the inner end of the push rod, and anti-slip pads are provided on the base plate of the clamping plate and the drive seat.

[0018] The above technical solution involves a rotating ring on the outer side of the clamping plate, which, in conjunction with a rotating block, enables a rotatable connection between the push rod and the clamping plate. The clamping plate, together with the base plate, holds the filter plate's wing plates, and anti-slip pads are provided on both to improve stability during clamping.

[0019] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0020] 1. This rapid separation device for filter press residue, suitable for use in steelmaking turbid circulating water, comprises a main screw, main motor, mounting plate, auxiliary screw, vertical drive assembly, moving base, sliding plates, and drive seat. During operation, the base is fixed to the filter press, and the vertical drive assembly moves the moving base, causing the drive seat to engage with the flanges of the filter plates. When cleaning the filter press residue is required, the auxiliary motor is activated, driving the auxiliary screw to rotate. Under the constraint of the auxiliary guide rod, several sliding plates move horizontally synchronously. Due to the different thread pitches of the various threaded sections on the auxiliary screw, the different sliding plates move different distances, thus moving multiple filter plates of the filter press by different distances, ensuring sufficient space between adjacent filter plates for the filter press residue to fall off. Then, the drive seat is moved upwards and the main motor is started. The main motor drives the main lead screw to rotate, and under the constraint of the column guide rod, the two mounting plates move horizontally synchronously, driving the vertical drive assembly, moving seat, auxiliary lead screw, and other components to move, so that the drive seat is aligned with the filter plate to be cleaned. The above steps are repeated to clean the filter cake. Multiple filter plates can be moved at a time, and there is cleaning space between each filter plate, which can greatly improve the separation speed of the filter cake.

[0021] 2. This rapid filter slag separation device, suitable for steelmaking turbid circulating water, uses a rotating push rod to move a clamping plate, adjusting the distance between the clamping plate and the base plate. This allows for clamping of filter plates of different thicknesses, enhancing its applicability. The clamping plate, in conjunction with the base plate, holds the filter plate's wings, and anti-slip pads are provided on both to improve stability during clamping.

Detailed Implementation

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figures 1-4As shown, this utility model includes two bases 1, a main lead screw 2 rotatably connected between the two bases 1, and a main guide rod 3 fixedly connected between the two bases 1. A main motor 4 capable of driving the main lead screw 2 is provided on one side of one of the bases 1. Two mounting plates 5 are rotatably connected to the main lead screw 2 and are sleeved on the main guide rod 3. A vertical drive assembly 14 is provided on the mounting plate 5. A movable seat 15 is fixedly connected to the output end of the vertical drive assembly 14. A secondary lead screw 6 is rotatably connected between the two movable seats 15. Several sets of threaded segments with gradually increasing thread pitch are sequentially opened on the secondary lead screw 6. A secondary guide rod 7 is fixedly connected between the two mounting plates 5. A secondary motor 8 capable of driving the secondary lead screw 6 is provided on one side of one of the movable seats 15. Several sliding plates 9 are threadedly connected to the secondary lead screw 6. A drive seat 10 is fixedly connected to the bottom surface of the sliding plates 9. The several sliding plates 9 are respectively arranged on different threaded segments of the secondary lead screw 6 and are sleeved on the secondary guide rod 7.

[0032] Example 1: A connecting plate is fixedly connected to the bottom of the base 1, and the main guide rod 3 is located below the main lead screw 2. The base 1 provides an installation platform for the main lead screw 2, the main guide rod 3, and the main motor 4. A connecting plate is provided on the bottom surface of the base 1 to facilitate fixing the base 1 to the filter press for operation. The main lead screw 2 is used to drive the mounting plate 5 to move along the direction of the main lead screw 2. The main guide rod 3 is used to constrain the mounting plate 5 to prevent the mounting plate 5 from rotating with the main lead screw 2. The mounting plate 5 adopts an L-shaped structure, and the auxiliary lead screw 6 is located on one side of the main lead screw 2. The mounting plate 5 provides an installation platform for the vertical drive assembly 14 and other structures, and can drive them to move. When the main motor 4 is started, the main motor 4 drives the main lead screw 2 to rotate. Under the constraint of the column guide rod 3, the two mounting plates 5 move horizontally synchronously, driving the vertical drive assembly 14, the moving seat 15, the auxiliary lead screw 6, and other components to move.

[0033] Example 2: The auxiliary guide rod 7 is located on one side of the auxiliary lead screw 6, and the number of thread turns on several threaded segments of the auxiliary lead screw 6 is the same. The auxiliary lead screw 6 is used to drive several sliding plates 9 to move horizontally. Several threaded segments with different pitches are opened on the auxiliary lead screw 6, so that it can drive several sliding plates 9 to move different distances. In this way, the filter plates of multiple filter presses can be moved to different distances, so that there is a certain space between adjacent filter plates, which provides conditions for cleaning the filter sludge. By controlling the number of thread turns of different threaded segments, the problem of motion interference between sliding plates 9 can be avoided. The middle position of the top surface of the drive seat 10 is fixedly connected to the sliding plate 9. The drive seat 10 drives the filter plate to move by clamping the wing plate on the side of the filter plate of the filter press. The auxiliary motor 8 is started to drive the auxiliary lead screw 6 to rotate. Under the constraint of the auxiliary guide rod 7, several sliding plates 9 move horizontally synchronously. Since the thread pitch of several threaded segments on the auxiliary lead screw 6 is different, the movement distance of different sliding plates 9 is different, thus driving the filter plates of multiple filter presses to move to different distances.

[0034] Example 3: The drive base 10 includes an L-shaped base plate and a vertical plate 11 fixedly connected to the base plate. A push rod 12 is threaded onto the vertical plate 11, and a clamping plate 13 is rotatably connected to the inner end of the push rod 12. The drive base 10 is used to limit the filter plates of the filter press and moves the filter plates under the drive of the sliding plate 9. By rotating the push rod 12, the push rod 12 moves the clamping plate 13, adjusting the distance between it and the base plate. This allows for clamping of the wing plates of filter plates of different thicknesses, thereby moving the filter plates. A rotating ring is fixedly connected to the outer side of the clamping plate 13, and a rotating block is fixedly connected to the inner end of the push rod 12 within the rotating ring. Anti-slip pads are provided on the clamping plate 13 and the base plate of the drive base 10. The rotating ring on the outer side of the clamping plate 13, in conjunction with the rotating block, enables the rotatable connection between the push rod 12 and the clamping plate 13. The clamping plate 13, in conjunction with the base plate, clamps the wing plates of the filter plates. The anti-slip pads on both improve the stability during clamping.

[0035] The working principle of this utility model is as follows:

[0036] S1. Fix the base 1 on the filter press, and at the same time use the vertical drive assembly 14 to drive the moving seat 15 to move, so that the drive seat 10 is sleeved on the wing plate of the filter plate of the filter press.

[0037] S2. When it is necessary to clean the filter cake, start the auxiliary motor 8 to drive the auxiliary lead screw 6 to rotate. Under the constraint of the auxiliary guide rod 7, several sliding plates 9 move horizontally in sync. Since the thread pitch of several threaded sections on the auxiliary lead screw 6 is different, the movement distance of different sliding plates 9 is different. In this way, the filter plates of multiple filter presses can be moved to different distances, so that there is a certain space between adjacent filter plates for the filter cake to fall off.

[0038] S3. Then move the drive seat 10 up and start the main motor 4. The main motor 4 drives the main screw 2 to rotate. Under the constraint of the column guide rod 3, the two mounting plates 5 move horizontally in sync, driving the vertical drive assembly 14, the moving seat 15, the auxiliary screw 6 and other components to move, so that the drive seat 10 is aligned with the filter plate to be cleaned. Repeat the above steps to clean the filter residue.

This rapid separation device for filter press residue in steelmaking turbid circulating water comprises a main screw 2, a main motor 4, a mounting plate 5, an auxiliary screw 6, a vertical drive assembly 14, a moving base 15, sliding plates 9, and a drive base 10. In operation, the base 1 is fixed to the filter press, and the vertical drive assembly 14 moves the moving base 15, causing the drive base 10 to engage with the flanges of the filter press plates. When cleaning the filter press residue is required, the auxiliary motor 8 is started, driving the auxiliary screw 6 to rotate. Under the constraint of the auxiliary guide rod 7, several sliding plates 9 move horizontally synchronously. Due to the different thread pitches of the various threaded sections on the auxiliary screw 6, the different sliding plates 9 move different distances, thus moving multiple filter press plates by different distances, ensuring sufficient space between adjacent filter plates for the filter press residue to fall off. Then, the drive seat 10 is moved upwards, and the main motor 4 is started. The main motor 4 drives the main lead screw 2 to rotate. Under the constraint of the column guide rod 3, the two mounting plates 5 move horizontally synchronously, driving the vertical drive assembly 14, the moving seat 15, the auxiliary lead screw 6, and other components to move, so that the drive seat 10 is aligned with the filter plate to be cleaned. The above steps are repeated to clean the filter residue. Multiple filter plates can be moved at a time, and there is cleaning space between each filter plate, which can greatly improve the separation speed of the filter residue.

[0041] 2. This rapid filter slag separation device, applicable to steelmaking turbid circulating water, uses a rotating push rod 12 to move the clamping plate 13, adjusting its distance from the base plate. This allows for clamping of filter plates of varying thicknesses, enhancing its applicability.
