Description

Technical Field

[0001] The utility model relates to the technical field of a dewatering filter cloth deviation correction mechanism, in particular to a bidirectional deviation correction mechanism. Background Art

[0002] Municipal and industrial flocculated sludge is dehydrated by sludge press. The sludge press uses a special filter medium to apply a certain pressure to the object, causing the liquid to seep out. It is a commonly used solid-liquid separation equipment. The most important component is the filter cloth. After long-term use, the filter cloth needs to be cleaned and usually needs to be rolled up after cleaning.

[0003] The existing patent CN117510020A discloses a filter cloth adjustment device, which is provided with a spiral roller, a frame, a swing frame and an adjustment component; the swing frame is installed on the frame, and on the frame, the two ends of the swing frame can swing up and down; the adjustment component is connected to the swing frame and is used to drive the swing frame to swing on the frame; the spiral roller is rotatably installed on the swing frame, and the swing frame and the spiral roller are both arranged perpendicular to the conveying direction of the filter cloth; the left side of the spiral roller is provided with a first spiral element, and the right side of the spiral roller is provided with a second spiral element, and the first spiral element and the second spiral element have opposite rotation directions. By providing the spiral roller, the wrinkled filter cloth can be flattened, and by providing the swing frame and the adjustment component, the offset filter cloth can be corrected. By providing the spiral roller on the swing frame, flattening and correcting can be achieved at the same time, the structure is simple, and the space occupied is smaller. Compared with the existing technology, the automation level is higher. In the above patent solution, electric cylinders are arranged on both sides to drive pistons and compress springs. When the filter cloth is offset, the electric cylinder on one side drives the piston to move, and the swing frame, guide roller and spiral roller move up. The springs on both sides are stretched against each other to keep the swing frame horizontal and correct the filter cloth. The solution also mentions the use of photoelectric sensors to monitor the swing amplitude of the swing frame.

[0004] However, in the above scheme, although the upgrade from manual correction to automatic correction is completed, its structure is relatively complicated, and a set of devices need to be set up on both sides to complete the correction work. Secondly, the electric cylinder pistons on both sides move up and down, which easily causes wrinkles on the filter cloth. Once wrinkles are formed on the filter cloth, it is difficult to smooth it in actual work. Utility Model Content

[0005] The utility model aims to provide a bidirectional deviation-correcting mechanism to solve the problem that the deviation-correcting mechanism for dewatering filter cloth currently used in the background art may cause wrinkles on the filter cloth.

[0006] To achieve the above objectives, the utility model provides the following technical solutions: a bidirectional deviation correction mechanism, comprising: a frame and a deviation correction roller, a guide roller is installed on the top of the frame, a fixed bracket is installed on the top of the frame, and the deviation correction roller is installed on the top of the frame.

[0007] Preferably, a rotating shaft is connected through the middle of the fixing bracket, and a connecting plate is installed on one side of the fixing bracket.

[0008] Preferably, a side of the connecting plate away from the fixed bracket is connected to a connecting block via a rotating shaft, and an electric push rod is installed on a side of the connecting block away from the connecting plate.

[0009] Preferably, a mounting frame is installed at the bottom of the electric push rod, and the bottom of the mounting frame is connected to the frame through a rotating shaft.

[0010] Preferably, a cloth receiving deviation correction sensor and a cloth discharging deviation correction sensor are respectively installed on both sides of the deviation correction roller.

[0011] Preferably, the bottom of the rotating shaft is connected to the frame, and the fixed bracket forms a rotating structure between the rotating shaft and the frame.

[0012] Compared with the prior art, the beneficial effect of the utility model is that when the two-way correction mechanism is in use, when the cloth-out correction sensor 11 senses that the position of the filter cloth is not in the center, the electric push rod can be controlled to move, so that the electric push rod is extended, and one side of the electric push rod is connected to the connecting plate through the connecting block, and the connecting plate is connected to the fixed bracket. At this time, the electric push rod will drive the fixed bracket to move through the connecting block and the rotating shaft, so that the fixed bracket rotates through the rotating shaft at the bottom, thereby correcting the filter cloth. Similarly, when collecting the cloth, the cloth will be sensed by the cloth collecting correction sensor, thereby realizing the two-way correction effect, and the position of the electric push rod will not move up and down, so that the filter cloth is not prone to wrinkles. This is the use feature of the two-way correction mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model provides a technical solution: a bidirectional deviation correction mechanism, comprising: a frame 1 and a deviation correction roller 4, a guide roller 2 is installed on the top of the frame 1, a fixed bracket 3 is set on the top of the frame 1, and the deviation correction roller 4 is installed on the top of the frame 1.

[0020] A rotating shaft 5 is connected through the middle of the fixed bracket 3, a connecting plate 6 is installed on one side of the fixed bracket 3, and a connecting block 7 is connected to the side of the connecting plate 6 away from the fixed bracket 3 through a rotating shaft, an electric push rod 8 is installed on the side of the connecting block 7 away from the connecting plate 6, and a mounting frame 9 is installed at the bottom of the electric push rod 8, and the bottom of the mounting frame 9 is connected to the frame 1 through a rotating shaft, a cloth receiving correction sensor 10 and a cloth discharging correction sensor 11 are respectively installed on both sides of the correction roller 4, the bottom of the rotating shaft 5 is connected to the frame 1, the fixed bracket 3 forms a rotating structure with the frame 1 through the rotating shaft 5, and the connecting plate 6 and the fixed bracket 3 are an integrated structure.

[0021] When the filter cloth is in the center position, the filter cloth is sensed by the cloth-out correction sensor 11 on one side of the correction roller 4. When the cloth-out correction sensor 11 senses that the filter cloth is deviated, the electric push rod 8 is automatically started to move. Since one side of the electric push rod 8 is connected to the connecting block 7, and the connecting block 7 is connected to one side of the fixed bracket 3 through a rotating shaft, the electric push rod 8 will push the fixed bracket 3 to rotate through the connecting block 7. At the same time, one end of the electric push rod 8 will rotate through the mounting bracket 9 at the bottom during rotation. Since the middle of the fixed bracket 3 is connected to the top of the frame 1 through a rotating shaft, the entire fixed bracket 3 drives the correction roller 4 to produce a correction action in the direction of the cloth deviation, thereby correcting the filter cloth and achieving the effect of returning the cloth to the right position. Similarly, when the filter cloth is rolled up, the cloth-collecting correction sensor 10 drives the correction roller 4 to produce the same action and effect according to the deviation state of the filter cloth, thereby completing the entire filter cloth correction work.

[0022] See also Figure 2 , Figure 3 and Figure 4 It can be seen that when in use, the position of the filter cloth can be detected by the cloth-out correction sensor 11 and the cloth-in correction sensor 10, and through the cooperation of the electric push and the connecting block 7, the fixed bracket 3 and the correction roller 4 can be pushed to rotate and swing, thereby correcting the filter cloth. There is no need to use two sets of mechanisms to achieve the correction. Secondly, the position of the electric push will not move up and down, so that the filter cloth is not prone to wrinkles.

[0023] To sum up: when in use, the two-way correction mechanism can wind the filter cloth to be rolled up onto the winding roller in the frame 1 through the guide roller 2 and the correction roller 4, and the filter cloth can be collected by the winding roller, and the position of the filter cloth can be sensed by the cloth-out correction sensor 11 and the cloth-collecting correction sensor 10 on the top of the frame 1. After sensing that the position is offset, the correction roller 4 is rotated through the cooperation of the electric push rod 8 and the connecting block 7, so that the correction roller 4 can play a correction role and facilitate the winding of the filter cloth. This is the use feature of the two-way correction mechanism.
