Description

Technical Field

[0001] The utility model relates to the technical field of filter discs of disc-type vacuum filters, in particular to a new filter disc with a single nozzle. Background Art

[0002] In the industrial production process, it is often necessary to use a disc vacuum filter to filter the slurry in order to collect the filtered mineral material. When using a disc vacuum filter to filter the slurry, a single-mouth filter disc is used.

[0003] At present, the single-mouth filter disc used in the disc vacuum filter is mainly composed of a filter disc body, a groove on the filter surface of the filter disc body, a filter cloth wrapped on the filter surface of the disc body, and a vacuum liquid suction pipe installed in the suction port of the filter disc body. Although the single-mouth filter disc with the above structure can filter the slurry when in use, on the one hand, since the filter surface on the filter disc body is a concave structure, it cannot reliably support the filter cloth, resulting in the single-mouth filter disc being easily subjected to a large force during use due to the lack of support in the middle of the filter cloth, thereby causing damage, shortening the service life of the filter cloth. On the other hand, since the filter cloth of the single-mouth filter disc with the above structure is fixed on the filter disc body in a wrapped form when in use, this will cause waste of the side edges of the filter cloth wrapped around the filter disc body, and the filter cloth on the single-mouth filter disc cannot be fully utilized. Utility Model Content

[0004] (1) Technical issues to be resolved

[0005] The technical problem to be solved by the utility model is to provide a new single-mouth filter plate which can not only reliably support the filter cloth when filtering the ore pulp, ensure that the filter cloth has sufficient strength during use and is not prone to rupture and damage, but also can conveniently fix the filter cloth by means of upper and lower clamping, thereby avoiding waste of the filter cloth after fixation.

[0006] (2) Technical solution

[0007] The utility model is achieved through the following technical solution: the utility model proposes a new single-mouth filter disc, including a filter disc body, an upper pressure strip is installed on the periphery of the upper end of the filter disc body, and a lower pressure strip is installed on the periphery of the bottom end of the filter disc body. A fixing groove is respectively opened on the filter disc body at the upper pressure strip and the lower pressure strip, and supporting protrusions are installed in the middle of the upper end and the middle of the bottom end of the filter disc body.

[0008] Furthermore, three through holes are provided in the middle of the filter disc body between the supporting protrusions, a liquid collection port is provided on one side of the filter disc body, and a liquid extraction pipe is installed on the filter disc body facing the liquid collection port.

[0009] By adopting the above technical solution, the through hole can ensure that the slurry passes through both sides of the filter disc body after the external filter cloth is installed, and the liquid collection port will collect the filtered slurry and pour it into the liquid extraction pipe.

[0010] Furthermore, the upper pressure strip and the lower pressure strip have the same structure, and both the upper pressure strip and the lower pressure strip are connected to the fixing groove via bolts.

[0011] By adopting the above technical solution, the upper pressing strip and the lower pressing strip can be reliably fixed.

[0012] Furthermore, the fixing groove is formed on the filter disc body, and the fixing groove is a fan-shaped annular structure.

[0013] By adopting the above technical solution, the fixing groove can realize the convenient placement and fixation of the filter cloth.

[0014] Furthermore, the supporting protrusion is formed on the filter disc body, and the end surface of the supporting protrusion is flush with the end surface of the filter disc body.

[0015] By adopting the above technical solution, the supporting protrusion enables the single-mouth filter disc to reliably support the filter cloth when in use, thereby preventing the filter cloth from being subjected to a large force due to the poor strength in the middle part during filtration, and preventing the filter cloth on the single-mouth filter disc from being broken and damaged during use, thereby improving the service life of the filter cloth on the filter disc body.

[0016] Furthermore, the through hole passes through the filter disc body, and the through hole is formed on the filter disc body.

[0017] By adopting the above technical solution, the stable arrangement of the through holes on the filter disc body can be ensured.

[0018] Furthermore, the liquid collection port is formed on the filter disc body, and the liquid collection port is communicated with the liquid extraction pipe.

[0019] By adopting the above technical solution, the liquid extraction pipe is connected to the external negative pressure suction pipe, so that the filtered slurry can be conveniently discharged by means of the negative pressure suction effect.

[0020] (3) Beneficial effects

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] In order to solve the problem that the single-mouth filter disc used in the current disc-type vacuum filter mainly consists of a filter disc body, a groove on the filter surface of the filter disc body, a filter cloth wrapped on the filter surface of the disc body, and a vacuum liquid suction pipe installed at the suction port of the filter disc body, the single-mouth filter disc with the above structure can filter the slurry when in use, but on the one hand, the filter surface on the filter disc body is a concave structure, which cannot reliably support the filter cloth, resulting in the single-mouth filter disc being easily subjected to a large force during use due to the lack of support in the middle of the filter cloth, thereby causing damage and shortening the service life of the filter cloth. On the other hand, since the filter cloth of the single-mouth filter disc with the above structure is fixed to the filter disc body in a wrapped form when in use The utility model discloses that the filter cloth is fixed on the filter disc body by the upper and lower edges of the filter disc body, thereby avoiding the waste of the filter cloth on the side edges of the filter disc body, and the filter cloth on the single-mouth filter disc can be fully utilized when in use.
