Background
The filter press realizes feeding and filter pressing by opening and forming a temporary closed cavity between filter plates. When the filter plates are closed and pressed tightly, a relatively closed cavity is formed between the filter plates, after materials are pressed into the cavity, liquid in the materials is discharged out of the cavity through the filter cloth under the action of pressure, and solid in the materials is trapped in the middle of the filter cloth in the cavity, and the process is called filter pressing.
When the filter plate is opened, the filter cake formed between the filter plate cavities separates from the filter plate, a process known as unloading. The rear end of a general filter press is provided with an extrusion oil cylinder which extrudes or stretches the filter press to open and close the filter plate. The opening and closing space of the filter plate of the existing filter press is limited by the stroke of the extrusion oil cylinder.

A plurality of filter plates 13 are arranged between the fixed end plate 11 and the movable end plate 12. The material to be treated is added between the filter plates 13, and after the filter plates 13 are pressed together, the filter plates 13 are pressurized to squeeze out the liquid in the material, thereby forming a mud cake. Two sides of the frame 1 are provided with side beams 14, and the two side beams 14 are in a plate-shaped structure and are arranged in parallel. The side members 14 are arranged in the longitudinal direction of the frame 1 and in the vertical direction in the width direction.
The frame 1 is provided with a driving support 2 which is arranged at the rear end of the movable end plate 12 and can move on the frame 1 and drive the movable end plate 12 to move. The two sides of the driving bracket 2 are provided with side beam sleeve holes 20, the side beams 14 pass through the side beam sleeve holes 20, and the edges of the side beam sleeve holes 20 are provided with rollers 3 rolling on the side beams 14, wherein the rollers 3 are arranged at the front and the rear of the side beam sleeve holes 20, the upper and the lower rollers 3 are respectively arranged at the front part, and the upper and the lower rollers 3 are respectively arranged at the rear part.
A hydraulic driving mechanism 21 for driving the roller 3 to rotate is arranged in the driving support 2, and the roller 3 runs on the side beam 14 when rotating, so that the movable end plate 12 is driven to move, and the filter plates 13 are driven to be pressed or separated mutually.
When the filter plate walking drive device of the filter press according to the embodiment is used, the rollers 3 roll on the side beams 14 and drive the drive brackets 2 to run, the frame 1 drives the movable end plate 12 to move back and forth during running, and when the movable end plate 12 moves towards one side of the fixed end plate 11, the filter plates 13 are pushed to approach and press; the rollers 3 continue to roll to press the filter plates against each other to filter the liquid. After the filter pressing is completed, the roller 3 runs on the side beam 14 in the other direction, and drives the driving bracket 2 and the movable end plate 12 to move, so that the filter plate 13 is separated. The filter press filter plate walking driving device can realize the synchronous opening and closing of all filter plates 13 of the filter press without depending on oil cylinders, and greatly reduces the length of the whole frame and the stroke in the filter pressing and separating processes.

The gear is meshed with the rack 15, the gear can move on the rack 15 under the action of teeth during rolling, and the roller 3 is placed to slip in the rolling process through the gear and the rack 15.
In one embodiment, as shown in fig. 2 and 3, the roller 3 includes a driving gear 31 and a driven gear, the driving gear 31 is connected to the hydraulic mechanism, the hydraulic mechanism drives the driving gear 31 to rotate so as to drive, and the driven gear rotates along with the driving. The driving gear 31 is disposed on a front side of a lower end of the side beam receiving hole 20, the driven gear includes a lower driven gear 32 and an upper driven gear, the lower driven gear 32 is disposed on a rear side of the lower end of the side beam receiving hole 20 opposite to the driving gear 31, and the upper driven gear is disposed on a front portion and a rear portion of an upper end of the side beam receiving hole 20.

Wherein, the supporting wheel 33 and the positioning wheel 34 apply downward pressure to the side beam 14, and the driving gear 31 and the driven gear apply upward pressure to the side beam 14, so that the matching between the roller 3 and the rack 15 is more stable. The positioning wheels 34 are arranged on one side of the upper part of the driving support 2, and the supporting wheels 33 are arranged on one side of the upper part of the driving support, so that the relative fixation of the positions is realized, the actual distance change of the side beams 14 is adapted, and more stable work is realized.
In one embodiment, hydraulic drive mechanism 21 includes a hydraulic pump 23 and a hydraulic ram 24. The hydraulic pump 23 is disposed in the middle of the rear of the drive bracket 2, and the hydraulic cylinders 24 are disposed on both sides of the middle of the drive bracket 2. The front side surface of the driving bracket 2 is provided with a first hydraulic motor 25, the output end of the first hydraulic motor 25 is connected with a first gear box 26, and the two output ends of the first gear box 26 are in the horizontal direction, opposite in direction and same in output speed.

The slide lock member slides along the slide rail under the driving of the hydraulic driving device so as to be brought into contact with and press-fitted to the side member 14, or to be separated from the side member 14 under the driving of the hydraulic driving device.
The slide lock of the drive bracket fixing bolt 22 increases friction by pressing against the side sill 14, thereby connecting and fixing the slide lock to the side sill 14. In the initial state, the slide lock is spaced apart from the side member 14, and when the driving bracket 2 is moved to a predetermined position, the hydraulic driving mechanism 21 starts to drive the slide lock to move so as to contact the side member 14 and apply a certain pressure to the side member 14. Thus, the position of the driving bracket 2 is fixed along with the driving bracket, and the problem of retraction can not occur.
Preferably, the number of the slide locks in the set of drive bracket fixing pegs 22 is two, one on each side of the side member 14, and the direction of movement of the slide locks is reversed. When the second hydraulic motor 28 drives the locking mechanism to lock, the two sliding locking pieces move towards each other, so that the side beam 14 is clamped; when the second hydraulic motor 28 actuates the locking mechanism to unlock, the two sliding locks move in opposition, disengaging from the side members 14. Through the synchronous work of two slip locking pieces, make locking mechanism and curb girder 14 be connected more firmly, avoid the single face to the curb girder 14 extrusion cause slope or connect unstable scheduling problem.
Preferably, the slide lock includes a slider and a lock lever. The sliding block is arranged on the guide rail and can move on the guide rail; the locking rod is arranged below the sliding block and extends into the side beam sleeve hole 20. The slide block is connected with a hydraulic driving device, and the hydraulic driving device drives the slide block to move so as to drive the locking rod to move. The guide rail comprises two parts, wherein one part is a front guide block, and the other part is a rear guide block. A certain gap is reserved between the front guide block and the rear guide block for installing the sliding block, and a dovetail rail is arranged on one side opposite to the front guide block and the rear guide block. Dovetail grooves are arranged on two sides of the sliding block, and the dovetail rails are clamped in the dovetail grooves.
In a preferred embodiment, the screw rod is provided with a first section of thread and a second section of thread which are opposite in spiral direction, and the sliding blocks of the two sliding locking pieces are respectively arranged on the first section of thread and the second section of thread. When the screw rod rotates, the sliding directions of the two sliding blocks are opposite. When the screw rod rotates in one direction, the spiral directions of the first section of threads and the second section of threads on the screw rod are opposite, so that the two sliding blocks matched with the screw rod can move in opposite directions. When the screw rotates forwards, the two sliding blocks approach each other, so that the locking rod clamps the side beam 14; when the screw is reversed, the two slides move away from each other, thereby moving the two lock levers away from the side beams 14.
In a preferred embodiment, the side beam 14 is provided with a thrust block 16 on the side, when the movable end plate 12 moves to a position where all the components are pressed together, the driving bracket 2 moves to the position of the thrust block 16, and the thrust block 16 is matched with the driving bracket 2 to fix the driving bracket 2, so that the pressure maintaining effect is realized in the filter pressing process.
