Description

Technical Field

[0001] The utility model relates to the field of suction filter barrels, and more specifically, to a suction filter barrel. Background Art

[0002] During the processing and production of rare earth products, a suction filter barrel is used to filter the materials to achieve solid-liquid separation. Currently, most suction filter barrels have a filter bag mounted on the barrel body as a filter component, and air is pumped from the bottom through an external negative pressure device to create the required negative pressure effect, thereby accelerating solid-liquid separation.

[0003] However, the current cooperation between the filter barrel and the filter bag mostly relies on the filter bag being installed on the top of the barrel body. Especially when there is a lot of filtering material and a large downward force is applied, the filter bag may become loose, making it difficult to maintain the bag opening open, and even the material may enter the barrel body directly without being filtered. Moreover, the whole filtration relies only on the filter bag, and it is impossible to separate large particles of debris in advance, which affects subsequent processing and treatment, and needs to be improved.

[0026] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0027] like Figures 1 to 5 As shown, a specific embodiment of the present invention discloses a suction filter barrel, including a barrel body 100 and a filter bag 200; a support member 110 is provided at the bottom of the barrel body 100, and a bracket is set on the top of the support member; the interior of the barrel body 100 is divided into a storage chamber 120 and a negative pressure chamber 130 that are connected to each other; the filter bag 200 is sleeved in the storage chamber 120, and the bottom of the filter bag is supported on the bracket, the side wall of the negative pressure chamber 130 is connected to an exhaust pipe 140, and the bottom of the negative pressure chamber 130 is connected to a drain pipe 150; a pressing piece 400 is sleeved and installed on the top of the barrel body 100, and the pressing piece is a ring-shaped structure for pressing the sleeve part of the filter bag and the barrel body; a filter screen 500 is set at the inner ring of the pressing piece 400.

[0028] The above-mentioned filter barrel supports the bottom of the filter bag by means of a bracket, thereby reducing the stress on the joint between the filter bag and the barrel body and preventing it from loosening; a pressing piece is sleeved on the top of the barrel body, and an additional structure is used to press the filter bag tightly, further preventing the filter bag from loosening; and a detachable structure is adopted, which facilitates the subsequent removal, disassembly and replacement of the filter bag.

[0029] A filter is installed on the inner ring of the pressing piece for pre-filtration to screen out large particles of impurities, reducing the work of subsequent processing and improving efficiency.

[0030] Furthermore, if Figures 2 to 4 As shown, a support ring 600 is installed on the top inner wall of the barrel body 100, and the top of the filter bag 200 is sleeved on the barrel body 100 and the support ring 600, and the port is turned outward to the outer wall of the barrel body; Figure 6 As shown, a card slot 410 is provided at the bottom of the pressing piece 400, and the card slot forms a closed loop structure around the center of the pressing piece. The thickness of the sleeve portion of the barrel body 100, the support ring 600, and the filter bag 200 is adapted to the width of the card slot 410. The pressing piece is clamped and mounted on the top of the barrel body to clamp the top of the filter bag. The design of the support ring thickens the inner side of the top of the barrel body, so that a gap is left between the filter bag below and the inner wall of the barrel body, which is convenient for subsequent negative pressure suction and accelerates the filtration and seepage of the liquid. In addition, the matching area with the filter bag and the pressing piece is expanded to further strengthen the overall clamping strength to prevent loosening.

[0031] Furthermore, at least two handles 420 are fixedly provided on the top surface of the pressing piece 400. The handles are distributed in a circular array around the axis of the pressing piece and serve as gripping parts to facilitate grasping the pressing piece for applying force and facilitating disassembly and assembly.

[0032] Furthermore, a reinforcement ring is fixedly provided on the outer ring of the filter screen 500, and the outer diameter of the reinforcement ring is adapted to the inner diameter of the pressure piece 400; a support ring 430 is fixedly provided on the bottom of the inner ring wall of the pressure piece 400, which is used to support the placement of the filter screen 500. A simple matching method is adopted, which can not only meet the required filtering effect, but also facilitate disassembly and assembly, and facilitate the cleaning of the filter residue.

[0033] Furthermore, if Figure 6 、 Figure 7As shown, a plurality of cylindrical support members 110 are fixedly provided on the inner wall of the bottom of the barrel body 100, and a first magnet block 160 is fixedly embedded on the top surface of the support member 110; the bracket 300 includes a circular support plate 310, the diameter of the support plate 310 is adapted to the inner diameter of the barrel body 100, and a plurality of through holes 320 are provided on the support plate 310, and the storage chamber 120 and the negative pressure chamber 130 are connected through the through holes 320; a plurality of second magnet blocks 330 are fixedly embedded on the bottom surface of the support plate 310, and the second magnet blocks 330 moved into position are magnetically connected with the first magnet blocks 160 ; The bracket is supported overhead by multiple supporting members so that it can be placed stably, providing stable support on the top and maintaining sufficient air extraction space in the negative pressure chamber below to meet the required negative pressure effect; furthermore, a plurality of through-holes 340 are provided on the support plate 310, and the number of the through-holes is an even number, and they are distributed in an array around the central circumference of the support plate. A frame bar 350 is fixed on the through-hole 340, and the frame bar is used as a hook to hook and pull the support plate, so that the support plate can be hooked and lifted, and it is easy to remove it; combined with the magnetic connection method, it can provide the required connection strength, and it is also more convenient to disassemble and use.

[0034] Furthermore, if Figures 3 to 5 As shown, the bottom of the negative pressure chamber is a bucket-shaped structure; the drain pipe 150 is connected to the concave center of the negative pressure chamber 130, and a solenoid valve 170 is installed at the drain pipe 150; the inner wall of the negative pressure chamber 130 corresponds to the connection between the exhaust pipe 140 and the barrel body 100, and the outer fixed cover is provided with a water shield 180, the bottom of the water shield is open, and there is a distance from the bottom upper edge of the negative pressure chamber; the bottom of the negative pressure chamber 130 corresponds to the bottom of the water shield 180 and a liquid level sensor 190 is installed, and the probe of the liquid level sensor is lower than the bottom end of the water shield; the connecting part of the exhaust pipe and the barrel body is shielded and protected by the water shield to prevent liquid falling from above from being pumped to the outside; through the liquid level sensor and The cooperation of the solenoid valve can not only maintain the required negative pressure space, but also prevent excessive internal liquid from overflowing into the exhaust pipe; more specifically, during the normal filtration process, the solenoid valve is in a closed state, and the external negative pressure equipment continues to pump air, the liquid at the bottom of the barrel increases, and the space shrinks, further enhancing the negative pressure effect; when the liquid level sensor detects liquid, the solenoid valve needs to be opened at this time, and will not be closed until the preset time, so as to quickly reduce the internal liquid, but will not affect the subsequent filtration action; it should be noted that the solenoid valve, liquid level sensor, and negative pressure equipment are all connected to the electrical control box and are controlled by the electrical control box. The above-mentioned electrical components are all common equipment and the cooperation method is relatively simple, so I will not go into details.

[0035] Furthermore, the outer wall of the water shield is a downwardly inclined conical structure, and a water retaining ring is fixedly provided on the inner wall of the bottom end of the water shield, which can accelerate the downward flow of liquid and effectively prevent the liquid from entering the interior of the water shield and prevent the droplets from being pumped out to the outside.
