Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a sludge plate and frame filter press. Background Art

[0002] A filter press is a mechanical device that uses a special filter medium to apply a certain pressure to an object so that the liquid can be dialyzed out. It is a commonly used solid-liquid separation device. Here it is mainly used for sludge filtration.

[0003] The application number 201921728763.2 discloses a sludge dewatering plate and frame filter press, belonging to the technical field of sludge dewatering. A sludge dewatering plate and frame filter press includes: a bracket, and further includes: a filtering mechanism, an output mechanism, and a power mechanism arranged on the bracket. The output mechanism is between the filtering mechanism and the power mechanism, and the output mechanism is arranged on the top of the filtering mechanism. The bracket includes a vertically arranged vertical plate, and a horizontally arranged connecting plate, a first support disk, and a second support disk are arranged on one side of the vertical plate. The first support disk is between the connecting plate and the second support disk. The first support disk and the second support disk are connected to the vertical plate through a fixing plate. This utility model can improve the amount of sludge processed per unit time by setting multiple dewatering devices, and improve the sludge dewatering efficiency. When this application is specifically used, once there is a lot of sludge in the outer cylinder, the sludge will pile up into a column, which instead increases the dewatering difficulty. Summary of the Utility Model

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by the utility model is as follows:

The filtering module includes a disk body connected to the top end of the shaft rod, two air cylinders vertically penetrating through the disk body, and a pressing disk connected to the two air cylinders. The pressing disk is slidably sleeved outside the shaft rod.

[0007] By adopting the above technical solution, after the sludge is piled up at the center of the base plate, the cylinder is started, then the pressing plate descends and contacts the top of the earth-pushing plate, and then the earth-pushing plate is pressed to rotate until it fits the top of the base plate. During this process, the inner sides of multiple earth-pushing plates will collide and press against each other, indirectly causing the sliding plates to move outwards, and then the sludge concentrated near the shaft rod is differentiated, ensuring that the sludge can be quickly flattened, thereby squeezing out the sewage in the sludge and effectively reducing the difficulty of sludge dewatering.

[0008] In a preferred embodiment of the present utility model, it can be further configured that: multiple slide rails are grouped in pairs and set in six groups.

[0009] In a preferred embodiment of the present utility model, it can be further configured that: multiple sliding plates are arranged at equal intervals and in a hexagonal shape, and the sliding plates and the earth-pushing plates are made of the same material.

[0010] In a preferred embodiment of the present utility model, it can be further configured that: two torsion springs are symmetric about the vertical central plane of the earth-pushing plate, and through holes suitable for the torsion springs to be embedded are provided on the inner side of the earth-pushing plate.

[0011] In a preferred embodiment of the present utility model, it can be further configured that: two cylinders are connected in series and electrically connected to an external power supply.

[0012] In a preferred embodiment of the present utility model, it can be further configured that: the diameter of the pressing plate is equal to the diameter of the base plate.

[0022] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0023] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model.

[0024] The following describes a sludge plate-frame filter press provided by some embodiments of the present utility model with reference to the accompanying drawings.

[0025] Embodiment 1:

[0026] Combined Figures 1-4 As shown, a sludge plate-frame filter press provided by the present utility model includes a holding module 100 and a pressure filtration module 200. The holding module 100 includes a base plate 110, a plurality of slide rails 120 installed on the top of the base plate 110, a slide plate 130 slidably connected between two slide rails 120, a shaft rod 140 connected to the top of the base plate 110, an elastic rope 150 connected between the slide plate 130 and the shaft rod 140, an earth-pushing plate 160 movably sleeved inside the inner end of the slide plate 130, and two torsion springs 170 connected between the slide plate 130 and the earth-pushing plate 160;

[0027] The pressure filtration module 200 includes a disc body 210 connected to the top end of the shaft rod 140, two air cylinders 220 vertically penetrating through the disc body 210, and a pressing disc 230 connected to the two air cylinders 220. The pressing disc 230 is slidably sleeved outside the shaft rod 140.

[0028] Furthermore, the plurality of slide rails 120 are grouped in pairs and set to six groups. With this structural design, it is ensured that each slide plate 130 can be limited.

[0029] Furthermore, the plurality of slide plates 130 are arranged at equal intervals and in a hexagonal shape. The slide plates 130 and the earth-pushing plates 160 are made of the same material. With this layout design, it is convenient to separate the piled-up sludge, making it easy for the pressing disc 230 to descend, and then squeezing out the water contained in the sludge.

[0030] Further, the two torsion springs 170 are symmetric about the vertical center plane of the bulldozing plate 160. Through holes adapted for the torsion springs 170 to be embedded are provided inside the bulldozing plate 160. The provision of the through holes provides an installation space for installing the torsion springs 170.

[0031] Embodiment 2:

[0032] Combined with Figures 1-4 As shown, on the basis of Embodiment 1, the two cylinders 220 are connected in series and electrically connected to an external power supply. With this structural design, the start and stop of the cylinders 220 will be easier.

[0033] Embodiment 3:

[0034] Combined with Figure 1 As shown, in the above embodiment, the diameter of the pressing plate 230 is equal to the diameter of the base plate 110. With this size design, the sludge on the base plate 110 can be completely flattened, and then the dewatering operation can be fully completed.

[0035] The working principle and usage process of the present utility model: In the initial state, the movable ends of the two cylinders 220 are in a contracted state, then the pressing plate 230 hangs above the base plate 110. Then, under the pulling of the elastic rope 150, the sliding plate 130 moves closer to the shaft rod 140, and then the bulldozing plate 160 is perpendicular to the sliding plate 130. When the device is put into actual use, the staff fills the center of the base plate 110 with sludge, and then starts the two cylinders 220. Then the pressing plate 230 descends. During the descent, the pressing plate 230 contacts the top of the bulldozing plate 160, and then the bulldozing plate 160 is pressed to rotate until it fits against the top of the base plate 110. During this process, the inner sides of the multiple bulldozing plates 160 will collide and press against each other, and then the sliding plate 130 will move outwards, and the sludge concentrated near the shaft rod 140 will be differentiated, ensuring that the sludge can be quickly flattened, thereby squeezing out the sewage in the sludge and effectively reducing the difficulty of sludge dewatering.
