Description

Technical Field

[0001] The utility model relates to the technical field of filters, and more particularly to a manganese sand filter. Background Art

[0002] Manganese sand filter composition: mainly composed of the following parts: supporting pipelines and valves. The filter body also includes:

[0003] ① Cylinder; ② Backwash air pipe; ③ Water distribution assembly; ④ Support assembly; ⑤ Filter material; ⑥ Exhaust valve (external), etc.

[0004] A manganese sand adsorption filter is a pressure-type filtration device using manganese sand as the filter medium. It can be connected in series with ion exchange softening and desalination equipment to form a treatment system. Using manganese sand as the filter medium, it filters high-turbidity water through a layer of granular or non-granular manganese sand at a certain pressure, effectively intercepting and removing suspended matter, organic matter, colloidal particles, microorganisms, chlorine, odor, and some heavy metal ions from the water. This high-efficiency filtration device ultimately reduces turbidity and purifies the water quality. Water with excessively high iron and manganese content is typically treated with a catalyst (such as manganese sand) to oxidize dissolved ferrous iron or manganese into insoluble ferric iron or tetravalent manganese compounds, respectively. This is then removed and purified using the backwash function of the manganese sand filter.

[0005] The existing manganese sand filter has a low filtration efficiency. For example, Chinese patent (CN 205832704 U) discloses a manganese sand filter. Three layers of manganese sand filter material are arranged under the baffle. The manganese sand filter material layer is stacked and motionless, resulting in a relatively low porosity of the filter material and easy clogging, resulting in low filtration efficiency. Therefore, it is necessary to improve the structure to make the filter material flow and increase the filtration efficiency. Utility Model Content

[0006] The purpose of the utility model is to provide a manganese sand filter in order to solve the above technical problems.

[0007] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0008] A manganese sand filter comprises a tank body, a manganese sand filter material layer and a lifting device; a bracket is provided near the bottom end of the tank body, and the manganese sand filter material layer is provided on the bracket;

[0009] The lifting device includes a motor, a screw rod and a vertical pipe. The vertical pipe and the screw rod are sleeved. The motor is installed on the top of the tank body. One end of the screw rod extends upward from the vertical pipe and is fixed to the output end of the motor. The other end of the screw rod extends downward from the vertical pipe.

[0010] The outer wall of the vertical pipe is sheathed with a vent pipe, and both ends of the vent pipe are welded to the vertical pipe. The outer wall of the bottom of the vent pipe is provided with multiple aeration pipes, each of which has multiple aeration holes. One end of the aeration pipe is connected to the vent pipe, and the other end is closed.

[0011] The number of the aeration pipes is at least three and they are evenly distributed around the ventilation pipe.

[0012] An air inlet pipe is provided on the top of the outer wall of the vent pipe, one end of which passes through the tank body and can be connected to the air outlet of an aeration fan or an air compressor, thereby facilitating the inflation of the vent pipe.

[0013] The outer wall of the vertical pipe is fixed with an annular shielding bucket, which is located at the bottom of the ventilation pipe. The gap between the edge of the annular shielding bucket and the inner wall of the tank is 80mm. The design of the annular shielding bucket allows the filter material to enter the bottom of the annular shielding bucket through the gap to reduce the pressure of the filter material on the spiral rod.

[0014] The vertical tube is provided with multiple through-holes, positioned lower than the aeration holes and with a diameter one-third that of the aeration holes. The through-holes are designed to allow gas to flow into the vertical tube, with some gas exiting from the bottom of the tube and some from the top. This allows aeration of both the filter media below and within the vertical tube, resulting in more complete aeration of the filter media. The diameter of the through-holes is designed to be smaller than that of the aeration holes, allowing most of the gas to flow into the aeration tube.

[0015] The inner wall of the tank is provided with multiple fixing seats. The number of fixing seats is the same as that of the aeration tubes. The fixing seats are assembled one-to-one with the aeration tubes. The fixing seats include a base and an upper seat. The base is welded to the tank body and screwed to the upper seat. The base is provided with a lower arc groove, and the upper seat is provided with an upper arc groove. The circular groove formed by the upper and lower arc grooves is used to cooperate with and fix the aeration tubes. The fixing seats play a role in fixing the aeration tubes. During installation, one end of the aeration tube is first placed in the lower arc groove, and then the upper seat and the base are assembled to fix the aeration tubes.

[0016] The sidewalls and bottom of the tank are both provided with access holes, with the sidewall access holes located above the fixing base. Designing access holes on both the sidewalls and bottom of the tank improves clearance efficiency, and the sidewall access holes are designed above the fixing base to facilitate maintenance and repair of the aeration pipe installation.

[0017] Working principle: When the lifting device is working, it drives the spiral rod to rotate, and the filter material at the bottom of the manganese sand filter material layer is transferred upward from the bottom of the vertical pipe, and falls out from the top of the vertical pipe back to the top of the manganese sand filter material layer, so as to achieve the purpose of filter material flow, so that the filter material, air and water are fully in contact, thereby improving the filtration efficiency.

[0018] The beneficial effects of the utility model are as follows:

[0019] By setting up a lifting device, the filter material can flow, so that the filter material, air and water can fully contact each other, thereby improving the filtration efficiency; by setting up a fixing seat, the aeration pipe can be fixed; by designing inspection holes on the side wall and bottom of the tank body, the gap efficiency is improved. The inspection hole on the side wall is designed above the fixing seat to facilitate the installation, maintenance and repair of the aeration pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The sidewall and bottom of the tank body 1 are both provided with inspection holes 18, and the inspection holes 18 on the sidewalls are located above the fixing base 13. By designing the inspection holes 18 on both the sidewalls and the bottom of the tank body 1, the clearance efficiency is improved.
