Description

Technical Field

[0001] This utility model relates to the technical field of filter press devices for sludge dewatering, and more specifically, it relates to a filter press device for sludge dewatering. Background Technology

[0002] In existing technologies, sludge dewatering filter presses are crucial equipment for sludge treatment. They apply pressure to squeeze out water from the sludge, thereby reducing its volume and stabilizing it. However, these devices may face the problem of excessive pressure during operation. If the filter press cannot effectively release pressure, the continuously rising pressure may damage the equipment. Such damage not only affects the normal operation of the equipment but may also lead to safety accidents, posing a threat to the safety of operators.

[0003] Furthermore, existing sludge dewatering filter presses may have inadequate pressure relief designs. In some cases, if pressure is not released in a timely manner, it can lead to filter cloth damage, frame deformation, or damage to other critical components. This not only shortens the equipment's lifespan but may also result in costly repairs. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a filter press device for sludge dewatering, which has the following beneficial effects:

[0017] 1. The adjustment mechanism provides a precise and flexible filter press pressure adjustment mechanism. Through the action of the hydraulic cylinder, the pressure plate can apply appropriate pressure to the sludge to achieve effective dewatering. At the same time, by adjusting the threaded sleeve, the position of the slider can be changed, thereby adjusting the compression distance of the spring and realizing the adjustment of overload pressure.

[0018] 2. The limiting mechanism is characterized by its reliable overload protection function. When the pressure exceeds the spring force, the engagement between the annular bar and the annular groove will be released, thereby preventing overload and avoiding damage to the equipment. At the same time, the configuration of the slider and the inclined groove enables the limiting mechanism to respond quickly to pressure changes, ensuring that the equipment operates within a safe working range.

[0019] 3. The extrusion mechanism, through the configuration of the pressure plate and guide rod, can apply pressure evenly to the sludge, thereby effectively squeezing out the water. At the same time, the design of the outer shell and the demolding tank allows the wastewater generated during the filter press process to be discharged smoothly, improving the operating efficiency and stability of the equipment.

The insertion rod 5 is connected to the extended end of the hydraulic cylinder 2. The fixed sleeve 4 is installed on the transmission rod 3, and the insertion rod 5 is slidably connected within the fixed sleeve 4. The limiting mechanism is connected to the fixed sleeve 4 and the annular bar 6. Multiple annular grooves 7 are equidistantly formed on the side wall of the insertion rod 5, and the annular bar 6 is engaged in the annular grooves 7. The limiting mechanism includes a slider 8. Multiple inclined grooves 9 are formed on the side wall of the fixed sleeve 4, and each inclined groove 9 is slidably connected to a slider 8. The multiple sliders 8 are respectively equipped with... There are springs 10, each spring 10 is equipped with a synchronization plate 11, and a ring bar 6 is installed on the synchronization plate 11. The synchronization plate 11 is attached to the insertion rod 5. Multiple sliders 8 are equipped with return springs 12, and multiple return springs 12 abut against the fixed sleeve 4.

[0031] More specifically, when it is necessary to change the overload pressure, firstly, by adjusting the threaded sleeve 14, the slider 8 can be driven to press against the inclined groove 9 to contract, thus changing the compression distance of the spring 10.

When the pressure exceeds the elastic force of the multiple springs 10, the engagement between the annular bar 6 and the annular groove 7 will be released, thus preventing overload and avoiding damage. When it is necessary to change the overload pressure, the adjusting threaded sleeve 14 can first drive the slider 8 to press against the inclined groove 9 and contract, thus changing the compression distance of the spring 10. Then, when the insertion rod 5 is inserted, it can be inserted into the synchronization plate 11 through the cone 101, which then causes the annular bar 6 to be locked in the annular groove 7, thus completing the adjustment process.
