Abstract
Description
Technical Field
[0001] This utility model relates to the field of spring base technology, and more specifically to a spring base for a plate and frame filter press separator that prevents springs from falling off or breaking. Background Technology
[0002] Plate and frame filter presses are important dewatering equipment in the sludge treatment process of water plants, offering advantages such as high filtration accuracy, strong adaptability to sludge types, flexible operation, and low cost. Our plant's sludge workshop is equipped with two sets of plate and frame filter presses and their supporting equipment. Each plate and frame filter press consists of a hydraulic system, a cleaning system, a squeezing system, a sludge feeding system, a chemical dosing system, and a filter plate moving system.
[0003] The filter plate moving system consists of an electric motor hydraulic system, a hydraulic motor hydraulic system, transmission gears, a double chain, and a plate separator assembled on the double chain. The plate separator in the plate and frame filter press primarily separates the filter plates in sequence, facilitating unloading, cleaning the filter cloth, and reassembly, thereby improving equipment operating efficiency, reducing manual labor intensity, and ensuring the continuity and stability of the operation process.
[0004] It typically consists of a spring, spring seat, and hook. The spring is generally made of high-strength alloy steel to ensure its elasticity and durability. The spring seat is used to fix the spring, ensuring that the hook can properly hook the filter plate and return to its original position during the plate separation process. During operation, it has been found that the spring hook is prone to detachment or breakage, posing a safety hazard. This can cause equipment damage or, more seriously, personal injury. For example, during the cleaning process, if one side of the spring detaches, the plate separator hook will not function properly, causing the filter plate to misalign. This can lead to the filter plate getting stuck during the descent of the cleaning arm, damaging the filter plate and the crane. If the spring hook breaks, it could strike the operator, causing personal injury.
[0005] Therefore, how to provide a spring base for a plate and frame filter press separator that increases the service life of the spring hook and reduces the failure rate, preventing the spring from falling off or breaking, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0006] In view of this, the present invention provides a spring base for a plate and frame filter press separator that prevents springs from falling off or breaking, thereby increasing the service life of the spring hooks and reducing the failure rate.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A spring base for a plate and frame filter press separator that prevents spring detachment and breakage, comprising:
[0009] The spring base body includes a fixing part, a connecting part, and an extending part. The fixing part is connected to the connecting part. The end of the fixing part away from the connecting part is provided with an installation groove. A sliding groove is provided between the fixing part and the connecting part. The sliding groove is adapted to a spring hook. The extending part is connected to the end of the connecting part away from the fixing part. A groove is provided between the extending part and the connecting part.
[0010] Furthermore, the spring base body is stepped, with the inner diameters of the fixing part, limiting head, connecting part, and extending part decreasing sequentially.
[0011] Furthermore, a limiting head is provided at the end of the connecting part that is connected to the sliding groove.
[0012] Furthermore, the bottom of the inserted portion is provided with a tapered inclined surface toward the spring hook.
[0013] Furthermore, the inner diameter of the sliding groove is larger than the inner diameter of the groove.
[0014] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a spring base for a plate and frame filter press separator that prevents spring from falling off and breaking. By setting an extension part, a connecting part and a sliding groove, the sliding groove is adapted to the spring hook. The spring hook is hung in the sliding groove, and the spring hook can rotate on the spring base body. The friction and shear force of the spring hook in the sliding groove are reduced, thereby increasing the service life of the spring hook and reducing the failure rate. Attached Figure Description

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.
[0020] See Figure 1-2 This utility model discloses a spring base for a plate and frame filter press separator that prevents spring detachment and breakage, comprising:
[0021] The spring base body includes a fixing part 1, a connecting part 2, and an extending part 3. The fixing part 1 is connected to the connecting part 2. The end of the fixing part 1 away from the connecting part 2 is provided with a mounting groove 4. A sliding groove 5 is provided between the fixing part 1 and the connecting part 2. The extending part 3 is connected to the end of the connecting part 2 away from the fixing part 1. A groove 6 is provided between the extending part 3 and the connecting part 2. The spring hook surrounds to form a through hole, which is adapted to the sliding groove 5. By setting the extending part 3, the connecting part 2, and the groove 6, the sliding groove 5 contacts the spring hook. The spring hook is hung in the sliding groove 5 and can rotate on the spring base body. The rotation of the spring hook in the sliding groove 5 reduces friction and shear force, thereby increasing the service life of the spring hook and reducing the failure rate.
