Description

Technical Field

[0001] The utility model relates to the technical field of vertical centrifuges, in particular to a fixing device for a filter bag in a vertical centrifuge. Background Art

[0002] Vertical centrifuge is a highly efficient solid-liquid separation equipment, which consists of a feeding device, a separation system, a filter bin, a discharge bin, a transmission system, a washing device and an electronic control device. In the process of using the vertical centrifuge, the filter bag plays a vital role as a filter medium. The solid particles in the suspension will be thrown to the filter bag by the centrifugal force, and the liquid will be filtered out through the filter bag to form a filtrate. In this way, the solid and liquid are effectively separated, achieving the goal of solid-liquid separation.

[0003] In the process of installing the existing filter bags, they are usually laid flat on the inner wall of the drum, and the bag mouth flange is only laid on the liquid blocking plate at the upper end of the drum. There is no fixing device on the liquid blocking plate for fixing the bag mouth of the filter bag. The high-speed rotation of the drum will cause the filter bag to move left and right and fall, which is easy to affect the centrifugal effect. Therefore, a fixing device for the filter bag in a vertical centrifuge is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a fixing device for filter bags in a vertical centrifuge to solve the problems raised in the above background technology.

[0010] As a further preferred embodiment of the present technical solution: the number of the fixing frames is 2-6, and the clamping blocks are matched with the fixing frames.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] When the utility model is used, the filter bag is spread into the inner wall of the drum, the bag mouth flange is spread on the liquid blocking plate, and then the clamping block is aligned and inserted into the fixing frame. At this time, the fixing ring presses the bag mouth flange, and the bag mouth flange is driven by the pressure ring to be inserted into the pressure groove. The anti-skid groove and the anti-skid protrusion can increase the friction force of the liquid blocking plate and the fixing ring on the bag mouth flange to press each other, so that the filter bag is not easy to move left and right, and the threaded rod is rotated to make the threaded rod push the insertion rod into the insertion hole. The insertion rod is tangent to the clamping block, and the clamping block can be fixed in the fixing frame, so that the fixing ring can always tightly close the bag mouth flange, thereby fixing the filter bag. When the drum rotates, the filter bag is not easy to move left and right and fall, and the centrifugal effect is not easy to be affected. BRIEF DESCRIPTION OF THE DRAWINGS
