Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to an improved water-permeable conveyor belt and a drum filter press thereof. Background Art

[0002] According to the retrieval of Chinese patent publication number: CN215462492U, a drum filter press is disclosed, which relates to the technical field of filter presses and solves the problem of fixed gaps in existing filter press drums. The key points of its technical solution are that it includes a support frame, on which an extrusion roller, a pulley and a driven wheel are supported, a hollow conveyor belt is sleeved on the outside of the pulley and the driven wheel, and a receiving hopper is fixedly arranged on the support frame. The extrusion roller includes an upper roller and a lower roller, and the upper roller is installed and connected to the support frame through a mounting frame and an adjusting bolt. The effect is that by adopting the above technical solution, a mounting frame that is movably installed and connected to the support frame up and down can be provided, so that the height position of the mounting frame can be adjusted as needed, and then the height position of the upper roller can be changed, and finally the gap between the extrusion rollers can be adjusted according to the actual processing material object.

[0003] After the existing drum filter press performs a filter pressing operation on the material, impurities are easily adhered to the surface of the conveyor belt. If it is not cleaned in time, it will affect the filtering effect of the conveyor belt, resulting in affecting the working efficiency and filtering effect of the machine during subsequent use. When the scraper and the sweeping wheel are provided to clean the surface in the above technical scheme, it is easy to be insufficiently cleaned and impurities remain. In addition, the water permeability of the conveyor belt of the existing filter press is directly related to the filter pressing effect. If the aperture of the conveyor belt is too large, impurities are easy to block the gaps in the conveyor belt. If the aperture of the conveyor belt is too small, it will cause insufficient water permeability, which also affects the efficiency of the filter pressing. For this reason, the utility model provides an improved permeable conveyor belt and a drum filter press thereof. Utility Model Content

In addition, the water permeability of the conveyor belt of the existing filter press is directly related to the filter pressing effect. If the aperture of the conveyor belt is too large, impurities are easily blocked in the gaps of the conveyor belt. If the aperture of the conveyor belt is too small, the water permeability will be insufficient, which also affects the efficiency of the filter pressing.

[0013] Beneficial Effects

[0014] The utility model provides an improved water-permeable conveyor belt and a drum filter press thereof. Compared with the prior art, the utility model has the following beneficial effects:

[0015] (1) The improved permeable conveyor belt and its drum filter press drive the eccentric wheel to rotate by starting the driving motor. The rotation of the eccentric wheel causes the rotating wheel, the cleaning plate and the cleaning brush to slide backward. The connecting rod at the rear end of the cleaning plate slides inside the fixed pipe, so that the reset spring begins to contract. Under the influence of the elasticity of the reset spring, the cleaning plate and the cleaning brush slide back and forth. The flushed permeable conveyor belt is brushed by the cleaning brush, and the sewage is discharged through the sewage pipe on the right side of the machine body. Driven by the driving motor, the cleaning plate and the cleaning brush slide back and forth, thereby realizing the brushing operation of material impurities adhered to the surface of the permeable conveyor belt, avoiding the situation where impurities adhere to the surface of the permeable conveyor belt, causing blockage and affecting the permeability, thereby improving work efficiency.

[0016] (2) The improved permeable conveyor belt and its drum filter press drive the piston rod, the connecting plate and the remover plate to slide downward synchronously by starting the material removal cylinder, and the material adhering to the surface of the upper extrusion roller is scraped off by the material removal plate. When the material removal plate scrapes off the material on the surface of the upper extrusion roller, the material removal plate and the buffer rod slide upward synchronously, thereby squeezing the buffer spring. The buffer spring makes the material removal plate always fit the surface of the upper extrusion roller. By providing a material removal mechanism, the material that may be adhered to the surface of the upper extrusion roller can be scraped off, thereby avoiding affecting the subsequent filtration quality due to a large amount of material adhering to the surface of the upper extrusion roller.

By providing the material removal mechanism 5, the material that may be adhered to the surface of the upper extrusion roller 4 can be scraped off, thereby avoiding the subsequent filtration quality being affected by the adhesion of more material to the surface of the upper extrusion roller 4.

[0031] The utility model also discloses an improved water-permeable conveyor belt of a drum filter press, comprising a plurality of guide rollers 21 rotatably mounted inside a machine body 1, a water-permeable conveyor belt 22 being mounted on the surface of the guide rollers 21, the inner surface of the water-permeable conveyor belt 22 being in contact with the surface of a lower squeezing roller 3, a motor being mounted on the rear side of the machine body 1 for driving the guide rollers 21 and the water-permeable conveyor belt 22 to rotate, the material of the water-permeable conveyor belt 22 being a polyurethane mesh belt, the length of which is 12600 mm, and the width of which is 1760 mm; the aperture size of the water-permeable conveyor belt 22 being: single layer, the surface layer mesh being 2*2 mm, the wire diameter being 0.9 mm in the horizontal direction and 2 mm in the vertical direction; since the conveyor belt is prone to deformation after long-term operation, thickening the longitudinal wire diameter can alleviate this problem; the cross section of the water-permeable conveyor belt 22 is set as a skirt edge from the original straight edge, so that the water-permeable area can be increased, and at the same time, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

When the material removal plate 54 scrapes off the material on the surface of the upper extrusion roller 4, the material removal plate 54 and the buffer rod 531 slide upward synchronously, thereby squeezing the buffer spring 532, and the buffer spring 532 makes the material removal plate 54 always fit the surface of the upper extrusion roller 4.
