Description

A tail-end treatment device for a quartz sand washing system Technical Field

[0001] This utility model relates to the field of quartz sand washing technology, specifically a tail-end treatment device for a quartz sand washing system. Background Technology

[0002] During the washing of quartz sand, wastewater, sludge, and residual impurities are generated. Tail-end treatment includes the treatment of these wastes to ensure environmental compliance and achieve the purpose of resource utilization. The tail-end treatment steps include wastewater treatment, sludge treatment, and solid waste treatment. Wastewater treatment involves the use of sedimentation tanks and flocculants. When wastewater is sedimentated, gravity settling is usually used.

[0003] In existing wastewater treatment processes, sludge and impurities inside the wastewater need to be allowed to settle before the wastewater can be discharged from the sedimentation tank to the next process. The settling time is long, which increases the wastewater treatment time and makes it inconvenient to filter sludge and impurities in the wastewater during the wastewater discharge process. Summary of the Invention

[0004] The purpose of this invention is to provide a tail-end treatment device for a quartz sand washing system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tail-end treatment device for a quartz sand washing system includes:

[0007] A filter chamber, wherein a support ring is fixedly installed inside the filter chamber;

[0008] A negative pressure assembly is fixedly installed on the outer surface of the filter chamber. The negative pressure assembly includes a vacuum pump fixedly installed on the outer surface of the filter chamber, and an annular tube is fixedly installed on the outer surface of the filter chamber.

[0009] A filter assembly is movably disposed inside a filter chamber. The filter assembly includes a filter cartridge, and a spiral blade is rotatably connected inside the filter cartridge.

[0010] The feeding assembly is fixedly embedded on the outer surface of the filter chamber.

[0011] Furthermore, the feeding assembly includes:

[0012] The hopper is fixedly installed on the inner surface of the filter chamber by a bracket;

[0013] Solenoid valve No. 2 is fixedly installed on the lower surface of the silo.

[0014] The feed pipe is fixedly embedded on the outer surface of the filter chamber, and one end is fixedly connected to the hopper.

[0015] The screw is rotatably connected inside the feed pipe;

[0016] Motor No. 2 is fixedly installed at one end of the feed pipe, and its output end is fixedly connected to one end of the screw rod.

[0017] Furthermore, the filter chamber is movably provided with a cover plate at its upper end, and both the cover plate and the outer surface of the filter chamber are symmetrically fixed with connecting ears, and bolts are connected between two adjacent connecting ears.

[0018] Furthermore, a water inlet pipe is fixedly embedded in the upper surface of the cover plate, multiple top blocks are fixedly installed at equal angles on the lower surface of the cover plate, a solenoid valve is fixedly installed at the lower end of the filter chamber, and a water level sensor is fixedly installed at the lower end of the filter chamber via a bracket.

[0019] Furthermore, multiple air intake pipes are fixedly embedded at equal angles on the outer surface of the annular tube, and the air intake pipes are fixedly installed through the filter chamber. One end of the air intake pipe is fixedly installed with a hemispherical cover by a bracket.

[0020] Furthermore, the filter cartridge is movably inserted into the support ring, a sealed bearing is fixedly embedded in the upper surface of the cover plate, a rotating shaft is fixedly installed in the inner ring of the sealed bearing, the rotating shaft is fixedly connected to the spiral blade, and a scraper is fixedly installed at the lower end of the spiral blade.

[0021] Preferably, a No. 1 motor is fixedly mounted on the upper surface of the cover plate by a bracket, and gears are fixedly mounted on the output end and the upper end of the shaft of the No. 1 motor, and the two gears are meshed and connected for transmission.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. The water level sensor detects the water level inside the filter chamber. When the water level reaches the set height, the No. 1 solenoid valve opens to discharge the filtered wastewater. This prevents the No. 1 solenoid valve from being constantly open, which would affect the negative pressure environment created by the negative pressure component inside the filter chamber. The cover plate can be removed by unscrewing the bolts, making it easy to replace the filter cartridge.

[0024] 2. The vacuum pump operates, pumping out the air inside the filter chamber and creating a negative pressure environment inside the filter chamber. This negative pressure environment blocks most of the sludge and impurities in the wastewater from the filter cartridge. The wastewater passes through the filter cartridge at a faster speed due to the negative pressure environment, which facilitates the filtration of sludge and impurities in the wastewater during the wastewater discharge process and speeds up the wastewater treatment process.

[0025] 3. When motor number one starts, it drives the rotating shaft and spiral blades to rotate. The spiral blades scrape off the sludge and impurities from the inner wall of the filter cartridge, maintaining the permeability of the filter cartridge. At the same time, it causes the sludge and impurities to accumulate inside the hopper. When solenoid valve number two starts, it allows the sludge to enter the discharge pipe. Motor number two starts, driving the spiral rod to rotate, causing the sludge and impurities to be discharged from the other end of the discharge pipe, reducing the moisture content inside the sludge and impurities.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please refer to Figures 1-5. In this embodiment of the present invention, a tail-end treatment device for a quartz sand washing system includes a filter chamber 1. A support ring 106 is fixedly installed inside the filter chamber 1. A negative pressure component 2 is fixedly installed on the outer surface of the filter chamber 1. The negative pressure component 2 includes a vacuum pump 201 fixedly installed on the outer surface of the filter chamber 1. An annular pipe 202 is fixedly installed on the outer surface of the filter chamber 1. A filter component 3 is movably disposed inside the filter chamber 1. The filter component 3 includes a filter cylinder 301. A spiral blade 303 is rotatably connected inside the filter cylinder 301. A feeding component 4 is fixedly embedded and installed on the outer surface of the filter chamber 1.

[0034] Specifically, the negative pressure component 2 creates a negative pressure environment inside the filter chamber 1 to accelerate the flow of wastewater through the filter cartridge 301. The spiral blades 303 scrape off the sludge and impurities from the inner wall of the filter cartridge 301, maintaining the permeability of the filter cartridge 301. Then, the sludge and impurities are discharged through the feeding component 4.

[0035] Example 1

[0036] As shown in Figures 1-3, in this embodiment, a water inlet pipe 103 is fixedly embedded on the upper surface of the cover plate 101, and multiple top blocks 102 are fixedly installed at equal angles on the lower surface of the cover plate 101. A solenoid valve 107 is fixedly installed at the lower end of the filter chamber 1, and a water level sensor 108 is fixedly installed at the lower end of the filter chamber 1 through a bracket.

[0037] In this embodiment, wastewater is introduced into the filter cartridge 301 through the water inlet pipe 103. The water level sensor 108 senses the water level inside the filter chamber 1. After the water level reaches the set height, the first solenoid valve 107 opens to discharge the filtered wastewater, thus avoiding the negative pressure environment created inside the filter chamber 1 by the negative pressure component 2 when the first solenoid valve 107 is always in the open state.

[0038] As shown in Figures 2-4, in this embodiment, multiple air inlet pipes 203 are fixedly embedded at equal angles on the outer surface of the annular pipe 202, and the air inlet pipes 203 are fixedly inserted through the filter chamber 1. One end of the air inlet pipe 203 is fixedly installed with a hemispherical cover 204 through a bracket.

[0039] In practice, the vacuum pump 201 operates, pumping out the air inside the filter chamber 1 through multiple air inlet pipes 203 and annular pipe 202, creating a negative pressure environment inside the filter chamber 1. As a result, most of the sludge and impurities in the wastewater are blocked by the filter cartridge 301. The negative pressure environment accelerates the flow of wastewater through the filter cartridge 301, making it easier to filter sludge and impurities in the wastewater during the wastewater discharge process and speeding up the wastewater treatment process.

[0040] As shown in Figures 2 and 3, in this embodiment, the filter cartridge 301 is movably inserted into the support ring 106. A sealed bearing 305 is fixedly embedded in the upper surface of the cover plate 101. A rotating shaft 302 is fixedly installed in the inner ring of the sealed bearing 305. The rotating shaft 302 is fixedly connected to the spiral blade 303. A scraper 304 is fixedly installed at the lower end of the spiral blade 303. A first motor 306 is fixedly installed on the upper surface of the cover plate 101 through a bracket. Gears 307 are fixedly installed at the output end of the first motor 306 and the upper end of the rotating shaft 302. The two gears 307 are meshed and connected for transmission.

[0041] In practice, motor 306 operates, which drives shaft 302 to rotate via gear 307, causing spiral blades 303 to rotate. Spiral blades 303 scrape off sludge and impurities from the inner wall of filter cartridge 301, maintaining the permeability of filter cartridge 301. At the same time, sludge and impurities accumulate inside silo 401 for easy discharge.

[0042] As shown in Figure 5, in this embodiment, the feeding assembly 4 includes: a hopper 401 fixedly installed on the inner surface of the filter chamber 1 by a bracket; a second solenoid valve 402 fixedly installed on the lower surface of the hopper 401; a feeding pipe 403 fixedly embedded in the outer surface of the filter chamber 1, with one end fixedly connected to the hopper 401; a screw rod 404 rotatably connected to the inside of the feeding pipe 403; and a second motor 405 fixedly installed at one end of the feeding pipe 403, with its output end fixedly connected to one end of the screw rod 404.

[0043] In practice, the second solenoid valve 402 is opened, allowing the sludge to enter the inside of the discharge pipe 403. The second motor 405 is turned, driving the screw rod 404 to rotate, so that the sludge and impurities are discharged from the other end of the discharge pipe 403, reducing the moisture content inside the sludge and impurities.

[0044] Example 2

[0045] Based on Example 1, in order to compensate for the problem that the filter cartridge 301 is located inside the filter chamber 1 and is inconvenient to replace.

[0046] As shown in Figure 2, in this embodiment, a cover plate 101 is movably provided at the upper end of the filter chamber 1. Connecting ears 104 are symmetrically fixedly installed on the outer surface of the cover plate 101 and the filter chamber 1. Bolts 105 are connected between two adjacent connecting ears 104.

[0047] In practice, the bolts 105 and connecting lugs 104 are fastened together, and the bolts 105 are then removed to make the cover plate 101 easy to remove and the filter cartridge 301 easy to replace.

[0048] In this utility model, in order to facilitate the operator's control of the utility model, a PLC controller can be set up, and the first solenoid valve 107, water level sensor 108, vacuum pump 201, first motor 306, second solenoid valve 402 and second motor 405 are all electrically connected to the PLC controller. The PLC controller is existing technology and will not be described in detail here.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
