Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal mine washing and beneficiation technology, specifically to a high-frequency screen pump pressure water treatment device for heavy media washing and beneficiation. Background Technology
[0002] In coal preparation plants, high-frequency screens are used to dewater middlings and gangue tailings from magnetic separation. The oversize material enters the middlings production line, while the undersize water flows by gravity into the thickener. However, in actual operation, the undersize water contains coarse coal slurry, and the gravity flow pressure is insufficient, often causing slurry blockages in the pipes and production stoppages, thus affecting the entire washing workshop. Therefore, this application proposes a high-frequency screen undersize water treatment device to solve the above problems. Utility Model Content
[0003] (a) Technical problems to be solved
[0004] To address the shortcomings of existing technologies, this utility model provides a high-frequency screen pump water treatment device for heavy media washing and screening, which solves the technical problems mentioned in the background.
[0005] (II) Technical Solution
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a heavy media washing and high-frequency screening pump pressure water treatment device, including a material box, an overflow pipe installed on the upper side wall of the material box, a connecting pipe installed at the bottom of the material box, a discharge valve installed on the connecting pipe, and the other end of the connecting pipe connected to a slurry pump through a flange, and the pump outlet end of the slurry pump connected to the discharge pipe through a flange, and a discharge valve installed on the discharge pipe.
[0007] Preferably, the hopper is a 50m thick steel plate welded together. 3 Material bin.
[0008] Preferably, the upper side of the material box is square and the lower side is inverted conical.
[0009] Preferably, the discharge valve and the discharge valve are respectively installed in the middle of the connecting pipe and the discharge pipe.
[0010] Preferably, the top of the hopper is open to allow the screened water to flow in by gravity.
[0011] Preferably, the bottom end of the overflow pipe is connected to a trench.
[0012] (III) Beneficial Effects
[0013] The beneficial effects of this utility model are as follows:
[0014] This type of high-frequency under-screen pump water treatment device for heavy media washing no longer relies on the under-screen water to flow into the under-screen water pipe by gravity. The under-screen water is first recovered into the material tank, and then flows into the material tank by gravity. The under-screen water is then pressurized by the slurry pump and transferred into the thickening tank, which makes the under-screen water flow rate faster and ensures that the pipe will no longer accumulate material and blockage, avoiding production shutdowns. In addition, an overflow pipe is connected above the side of the collection, and the overflow pipe enters the trench to avoid overflowing. Attached Figure Description

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] like Figure 1-3 As shown, this utility model provides a technical solution: a high-frequency under-screen pump water treatment device for heavy media washing, including a material tank 1. The top of the material tank 1 is open for gravity flow of under-screen water. The material tank 1 is a 50m high-strength steel plate welded together. 3The material bin 1 has a square upper side and an inverted cone lower side. An overflow pipe 2 is installed on the upper side wall of the material bin 1, with its bottom end connected to a trench. A connecting pipe 3 is installed at the bottom of the material bin 1, with a discharge valve 4 installed on it. The other end of the connecting pipe 3 is connected to a slurry pump 5 via a flange, and the pump outlet of the slurry pump 5 is connected to a discharge pipe 6 via a flange. The slurry pump 5 is connected to the connecting pipe 3 and the discharge pipe 6 via flanges for easy disassembly and maintenance. The wastewater from the high-frequency screen is first collected by gravity back to the material bin 1. The slurry pump 5 pressurizes the screened water and transfers it into the thickening tank through the connecting pipe 3 and the discharge pipe 6, making the screened water flow faster and ensuring that the pipes conveying the screened water are no longer blocked by material accumulation, avoiding production impact and providing better protection for the overall equipment. Through the overflow pipe 2 connected to the upper side of the material tank 1, the screened water at a high level in the material tank 1 can overflow into the ditch, preventing the material tank 1 from overflowing. The discharge pipe 6 is equipped with a discharge valve 7, and the discharge valve 4 and discharge valve 7 are respectively installed in the middle of the connecting pipe 3 and the discharge pipe 6.
[0021] The operational steps for this application are as follows:
[0022] The underflow from the high-frequency screen is first recycled to the material tank 1 by gravity. The underflow is then pressurized by the slurry pump 5 and transferred to the thickening tank through the connecting pipe 3 and the discharge pipe 6, which makes the underflow flow faster and ensures that the pipes transporting the underflow will not accumulate material and become blocked, thus avoiding production disruptions. The underflow in the material tank 1 can be overflowed into the ditch through the overflow pipe 2 connected to the upper side of the material tank 1, thus preventing the material tank 1 from overflowing.
