All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0025] As Figure 1 shown, in the current technology, there is no sealing notch designed at the connection pipe 3 at the bottom of the filter fan, and there is no seal provided at the connection between the connection pipe 3 and the filtrate pipe, which easily causes filtrate leakage and erosion wear at the installation joint; and when the filter cloth is sleeved on the filter fan, the filter cloth cannot be effectively pressed and fixed at the end face 13, and the flatness of the fit between the filter cloth and the filter fan cannot be ensured. The formation of wrinkles in the filter cloth will accelerate the wear of the filter cloth by the slurry. Based on this, the present invention provides a filter fan and a pressure filter, by providing a plurality of mounting members at the end plate of the filter fan body, one end of the filter cloth is connected to the end plate of the filter fan body through the mounting member, and the other end is connected to one end of the end plate far from the filter fan body, thereby avoiding the situation that the slurry flows through due to poor sealing and accelerating the wear of the filter fan after flowing into the end plate.

[0026] Figure 2 As shown in the structural schematic diagram of a filter fan provided by the present invention, as Figure 2 shown, the filter fan mainly includes: a filter fan body 100 and a filter cloth 200, and the filter cloth 200 is connected to the filter fan body 100 through a mounting member 120.

[0027] Among them, the filter fan body 100 includes a first filter screen, a second filter screen, an end plate 110 and a support frame. The first filter screen and the second filter screen are symmetrically arranged on both sides of the support frame. One end of the support frame is provided with an end plate 110, and the other end is provided with a filter fan connection pipe 400. A plurality of mounting members 120 are arranged along the length direction of the end plate 110 on the end plate 110. The first filter screen, the second filter screen, the support frame and the end plate 110 form a space for filtering.

[0028] The filter cloth 200 is sleeved on the outside of the filter fan body 100, and one end of the filter cloth 200 is connected to the end plate 110 of the filter fan body 100 through a mounting member 120, and the other end is connected to the filter fan connection pipe 400.

[0029] Further, the end of the filter cloth far from the end plate can be fixedly connected to the filter fan body through a clamp structure.

[0030] The utility model fixes the filter cloth 200 on the filter fan body 100 through the mounting member 120, thereby solving the technical problem that the filter cloth 200 and the filter fan wear quickly when the pressure filter processes fine and hard materials such as phosphorus tailings and iron concentrates, and avoiding the uneven pressing and easy wrinkling of the filter cloth 200 during installation, which accelerates the wear of the filter cloth 200 by the slurry and thus accelerates the wear of the filter fan.

[0031] In an alternative embodiment, the mounting member 120 includes a first mounting structure and a second mounting structure. A plurality of the first mounting structures are uniformly arranged along the length direction of the end plate 110, and the second mounting structure is detachably connected to the first mounting structure.

[0033] In an alternative embodiment, the mounting hole is a blind hole.

[0034] Specifically, as Figure 2 shown, a plurality of mounting members 120 are uniformly arranged on the end plate 110 along the length of the end plate 110. The mounting members 120 include, but are not limited to, threaded structures, snap structures, and pin structures, etc. The mounting member 120 in this application adopts a dowel pin type blind hole structure. Among them, the first mounting structure is a blind hole, and the second mounting structure is a dowel pin. A blind hole is provided on the end plate 110, and the depth of the blind hole is less than the thickness of the end plate 110. One end of the filter cloth 200 is abutted against the end plate 110, and the dowel pin is inserted into the blind hole, thereby fixing the filter cloth 200 on the filter fan body 100.

[0035] Through the dowel pin type blind hole design at the end plate 110 of the filter fan, the filter cloth 200 can be well installed and pressed on the filter fan, and due to the dowel pin type blind hole design, it is avoided that the slurry flows through due to poor sealing and accelerates the wear of the filter fan after flowing into the end plate 110.

[0036] In an alternative embodiment, the filter fan body 100 is a filter fan made of stainless steel.

[0037] Specifically, as Figure 3 shown, in the prior art, when the two planes of the fan plate supporting the filter cloth 200 are made of flat plates and the two plates are uniformly perforated, and the opening rates are the same, the supporting strength of the filter cloth 200 is high, which improves the working pressure and the service life of the filter cloth 200. In this application, the filter fan body 100 is made of stainless steel parts, and the first filter screen, the second filter screen and the support frame are fixedly connected through a welding structure, and its structural rigidity is high, or the filter fan body 100 is integrally formed of stainless steel.

[0038] In this application, all parts of the filter fan are made of stainless steel, which is suitable for corrosion-resistant and wear-resistant solid-liquid separation of fine and hard materials, scenarios such as concentrate dehydration and tailings dry discharge, thus solving the drawback of the filter fan being damaged due to local corrosion and greatly extending the overall service life of the filter fan.

[0042] Specifically, as Figure 2 shown, a seal 410 is provided at the filter fan connection pipe 400 of the filter fan, and the seal 410 is arranged at the connection between the filter fan connection pipe 400 and the filtrate pipe, thus solving the technical problem that the joint between the filter fan and the filtrate pipe is prone to air leakage and slurry running, which exacerbates the wear of the filter fan.

[0043] Furthermore, a sealing groove is provided on the outer peripheral surface of the filter fan connection pipe 400, and the seal 410 is installed in the sealing groove, and the gap at the connection between the filter fan connection pipe 400 and the filtrate pipe is sealed by the seal 410. In this application, the seal 410 is an O-ring seal.

[0044] The filter fan of the present utility model is made of stainless steel, which solves the drawback of the filter fan being damaged due to local corrosion, greatly extends the overall service life of the filter fan, and is suitable for corrosion-resistant and wear-resistant solid-liquid separation of fine and hard materials, scenarios such as concentrate dehydration and tailings dry discharge; the joint between the filter fan connection pipe 400 and the filtrate pipe is sealed with an O-ring to solve the problem that the joint between the filter fan connection pipe 400 and the filtrate pipe is prone to air leakage and slurry running, which exacerbates the wear of the filter fan; a stud-type blind hole design is adopted at the end plate 110 of the filter fan, and the filter cloth 200 can be well installed and pressed on the filter fan, and due to the stud-type blind hole design, the situation of slurry flowing through due to poor sealing and accelerating the wear of the filter fan after flowing into the end plate 110 is avoided.
