Description

Technical Field

[0001] The utility model relates to a filter cloth replacement tooling for a filter press. Background Art

[0002] The filter cloth used when a hyperbaric filter press works is a commonly used, consumable and easily damaged part, and it needs to be replaced with a new one regularly or when it is damaged. Initially, the solution for replacing the filter cloth in the equipment technical instruction was to use a lifting device to lift the filter plate (the weight of a single filter plate can reach 800 Kg) with the filter cloth installed out of the filter press as a whole and move it to a platform to replace the filter cloth. After installation, the filter plate was placed on the frame by the lifting device. The time required to replace the filter cloth was relatively long and the workload was large. Subsequently, this solution was basically abandoned.

[0003] Currently, when the filter cloth needs to be replaced on site, the operator directly stands on the water receiving flap under the filter plate. However, the long-term overloaded standing behavior is likely to cause serious deformation of the water receiving flap, and the water isolation and diversion function of the water receiving flap has partially failed. Moreover, there are serious safety hazards when people stand on the severely deformed water receiving flap. Therefore, a filter cloth replacement tooling for a filter press is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a filter cloth replacement tooling for a filter press to solve the problem that when the filter cloth of the current filter press needs to be replaced, the operator directly stands on the water receiving flap under the filter plate, but the long-term overloaded standing behavior is likely to cause serious deformation of the water receiving flap, and there are serious safety hazards when people stand on the severely deformed water receiving flap as mentioned in the above background art.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A filter cloth replacement tooling for a filter press includes two groups of load-bearing crossbeams arranged at the filter press. Both ends of the two groups of load-bearing crossbeams are connected with handrail support ladders through fixing bolts. One end of the two groups of handrail support ladders far away from the load-bearing crossbeams is fixedly connected through fixing bolts with an operation board for the operator to stand on.

[0006] Preferably, the length of the two groups of load-bearing crossbeams is greater than the width of the filter press frame, so that the load-bearing crossbeams connecting the handrail support ladders can be lapped at the filter press frame.

[0007] Preferably, the length of the operation board is less than the width of the filter press frame, so that the operation board can be arranged at the filter press frame.

[0008] Preferably, the handrail support ladder includes two groups of handrail support rods, and multiple groups of ladder rods are arranged between the handrail support rods.

[0009] Preferably, a connecting rod is arranged at the top end of the handrail support ladder, and the length of the connecting rod is greater than the width between the two groups of load-bearing crossbeams, so that the connecting rod can drive the handrail support ladder to be lapped at the load-bearing crossbeams.

[0010] Preferably, both ends of the operation board are respectively connected to the end ladders of two groups of handrail support ladders, so that the end ladders of the handrail support ladders support the operation board.

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

[0012] Through the tooling provided by the present utility model, the operator no longer needs to stand on the water receiving flap under the filter plate to replace the filter cloth, thus avoiding the deformation of the water receiving flap due to long-term overload and the resulting safety hazards.

[0013] Compared with the method of replacing the filter plate by traditional lifting equipment, this tooling allows the operator to directly replace the filter cloth beside the filter press, reducing the movement and lifting of the filter plate, thereby reducing the workload. It reduces the dependence on large lifting equipment and lowers the economic cost of replacing the filter cloth. Since the movement and lifting steps of the filter plate are reduced, the process of replacing the filter cloth is faster, thus saving the time required for replacing the filter cloth.

[0014] The design of the tooling enables the operator to replace the filter cloth more quickly and conveniently, improving the overall work efficiency. At the same time, it avoids equipment damage caused by the operator standing on the water receiving flap and extends the service life of the equipment. The design of the tooling allows it to adapt to filter presses of different sizes and has good versatility.

[0015] The design of the load-bearing crossbeam and the handrail support ladder provides a stable support structure, ensuring the stability of the operator when replacing the filter cloth. The design of the operation board enables the operator to stand and operate conveniently, and the handrail support ladder provides additional support and safety guarantee.

[0020] In order to facilitate the solution of the problem that when the filter cloth of the current filter press needs to be replaced, the operator stands directly on the water receiving flap under the filter plate. However, the behavior of standing on it for a long time under overload is likely to cause serious deformation of the water receiving flap, and there are serious safety hazards for people standing on the severely deformed water receiving flap. The embodiment of the present utility model provides a filter cloth replacement tooling for a filter press. The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Please refer to Figures 1-3 , the present utility model provides a filter cloth replacement tooling for a filter press, including two groups of load-bearing crossbeams 1 arranged at the filter press. Both ends of the two groups of load-bearing crossbeams 1 are connected with handrail support ladders 2 through fixing bolts. One end of the two groups of handrail support ladders 2 far from the load-bearing crossbeams 1 is fixedly connected with an operation board 3 for the operator to stand on through a fixing bolt.

[0022] The lengths of the two groups of load-bearing crossbeams 1 are greater than the width of the filter press frame, so that the load-bearing crossbeams 1 connecting the handrail support ladders 2 are lapped at the filter press frame.

[0023] The length of the operation board 3 is less than the width of the filter press frame. So that the operation board 3 is arranged at the filter press frame.
