Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a vacuum slide structure of a filter. Background Art

[0002] The rubber vacuum belt filter is a new, highly automated and efficient filtration device. Using filter cloth as the medium, the slurry is placed on the cloth. The filter utilizes the slurry's gravity and vacuum suction to allow the liquid to pass through the cloth while the solids are trapped on the cloth, achieving solid-liquid separation. The rubber belt vacuum filter's endless rubber belt is driven continuously by a motor. The friction ring forms a watertight seal between the belt and the vacuum slide, preventing damage to the vacuum environment.

[0003] Existing vacuum slides, for example, the Chinese utility model patent with publication number CN209530280U discloses a slide for a rubber vacuum belt filter, comprising: a horizontally arranged rubber belt, a vacuum slide being provided at the lower part thereof, a vacuum area being provided on the front of the vacuum slide, a plurality of vacuum chutes being provided in the vacuum area, a number of lubricating water inlet holes being provided on both sides of the vacuum slide, the lubricating water inlet holes being connected to the chute through the outlet trough, a friction belt being provided in the chute, the friction belt being tightly attached to the chute and the rubber belt, and during long-term use, the rubber belt or the friction belt will inevitably wear out due to friction, resulting in the rubber belt and the friction belt not being able to fit tightly, thereby destroying the vacuum environment.

DETAILED DESCRIPTION

[0017] The present invention will be described in further detail below with reference to the accompanying drawings.

[0018] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0019] Example: Figure 1 and Figure 2 As shown, a vacuum slide structure of a filter includes a slide body 1 and a floating plate 2 . A vacuum chamber 101 is provided in the middle of the slide body 1 , and a filter cavity 102 and a discharge hole 103 are provided below the vacuum chamber 101 .

[0020] The two floating plates 2 are symmetrically distributed on the slide body 1. The slide body 1 is provided with mounting areas 104, which are located on the left and right sides of the vacuum chamber 101. The two floating plates 2 are mounted in the corresponding mounting areas 104.

[0021] The upper end of the floating plate 2 is provided with a chute 201, and the friction belt 3 is provided in the chute 201. The side end of the floating plate 2 is provided with a liquid injection hole 202, which is connected to the chute 201 and the lubricating liquid is injected into the chute 201 through the liquid injection hole 202.

[0022] Floating plate 2 is connected to the slide body 1 via an elastic assembly, which includes a spring 5 connected between the two. A gap exists between the lower end of floating plate 2 and the bottom of mounting area 104, allowing floating plate 2 to move downward when pressure is applied. When the pressure on floating plate 2 decreases, the elastic force of spring 5 pushes floating plate 2 upward.

[0023] A first mounting hole 105 is provided in the mounting area 104, and a positioning column 4 is provided at the bottom of the floating plate 2. The positioning column 4 is inserted into the first mounting hole 105. The positioning column 4 and the first mounting hole 105 ensure that the floating plate 2 will not move when subjected to a non-vertical force.

[0024] A second mounting hole 401 with an opening facing downward is provided at the lower end of the positioning post 4 . One end of the spring 5 extends into the first mounting hole 105 , and the other end extends into the second mounting hole 401 .

[0025] A sealing member 6 is provided in the installation area 104 , and the sealing member 6 is filled between the inner side wall of the installation area 104 and the side end surface of the floating plate 2 .
