Description

Technical Field

[0001] The present application relates to the technical field of water treatment, and in particular to a reclaimed water sedimentation device. Background Art

[0002] The production of silicon-manganese alloy is a high-temperature smelting process, and the electric furnace equipment must be able to withstand high temperatures above 800°C. Under such high temperature conditions, steel equipment itself cannot withstand it and must be cooled by water. If tap water is used for cooling, the chloride ions in the tap water will corrode the equipment over a long period of operation, which is not conducive to the long-term operation of the equipment. At the same time, the production volume of silicon-manganese alloy is large, and a large amount of water resources need to be introduced. In order to save resources and reduce production costs, reclaimed water is used to cool steel equipment in actual factory production.

[0003] The quality of reclaimed water is between sewage and tap water. It is non-drinking water that meets national standards after purification of urban sewage and wastewater. It can be used within a certain range. It can be used to flush toilets, cars, road greening, watering green land, and compensate for boiler water. There are also some impurities in reclaimed water. When reclaimed water is used to cool down the equipment in the production of silicon-manganese alloy, these impurities tend to accumulate in the pipes over time, resulting in poor pipe flow or even blockage. The pipes need to be unblocked, which is not conducive to long-term and stable cooling of the equipment. Therefore, the impurities in the reclaimed water need to be treated by sedimentation, filtration, etc. and used as cooling water for equipment cooling.

[0004] Inclined plate sedimentation tank is a widely used water treatment device at present. Inclined plate sedimentation tank has fast sedimentation speed and good sedimentation effect. Existing inclined plate sedimentation equipment is generally composed of multiple inclined plates arranged side by side. However, when the existing inclined plate sedimentation tank on the market is in use, the inclined plate is fixedly connected to the inside of the sedimentation tank. When there is a lot of sediment on the inclined plate and it needs to be cleaned, it is necessary to stop the sedimentation and take out the internal inclined plate for cleaning. This will result in a short cleaning cycle of the inclined plate when used for large-scale water treatment, which will lead to a reduction in water treatment volume and reduce the sedimentation efficiency of the water.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0029] like Figure 1 , Figure 2 , Figure 3 As shown, the present application provides a medium-water sedimentation device, including: a sedimentation tank 1, in which a first baffle 110, a second baffle 120 and a third baffle 130 are arranged, the first baffle 110 and the side wall of the sedimentation tank 1 form a mixing chamber 2, a buffer chamber 3 is formed between the first baffle 110 and the third baffle 130, a sedimentation chamber 4 is formed between the third baffle 130 and the side wall of the sedimentation tank 1 away from the first baffle 110, the mixing chamber 2, the buffer chamber 3 and the sedimentation chamber 4 are connected, a water inlet 140 is arranged at the upper part of the mixing chamber 2, and a sewage outlet 150 is arranged at the bottom of the sedimentation chamber 4.

[0030] The sedimentation chamber 4 includes a sludge area 410, an inclined plate area 420 and a clean water area 430 arranged from bottom to top. The inclined plate area 420 includes a plurality of inclined plates 421 arranged in parallel, an upper connecting rod 422, a lower connecting rod 423 and a telescopic cylinder 440. The inclined plate 421 includes an upper plate body 5 and a lower plate body 6. A groove 510 is opened inside the upper plate body 5. A part of the lower plate body 6 extends into the groove 510, and a spring 511 is arranged in the groove 510. One end of the spring 511 is connected to the top of the lower plate body 6, and the other end of the spring 511 is connected to the top of the groove 510. The upper part of the upper plate body 5 is connected to the upper connecting rod 422, the lower part of the lower plate body 6 is connected to the lower connecting rod 423, the output end of the telescopic cylinder 440 is connected to the bottom of the lower connecting rod 423, and an overflow port 431 is arranged on one side of the clean water area 430.

[0031] Specifically, the first partition 110, the second partition 120 and the third partition 130 are used to divide the space in the sedimentation tank 1 into a mixing chamber 2, a buffer chamber 3 and a sedimentation chamber 4. The mixing chamber 2 is used to mix the reclaimed water entering the mixing chamber 2 with a reagent, such as a flocculant, to flocculate the impurities such as suspended matter in the reclaimed water, forming alum flocs with larger particle sizes, which are convenient for the sedimentation of impurities under the action of gravity. The buffer chamber 3 has a buffering effect on the flow of the reclaimed water containing the reagent, so that the flow of the reclaimed water tends to be stable. The sedimentation chamber 4 is used to settle the reclaimed water containing impurities under the action of gravity, so as to achieve the effect of preliminary impurity removal. The water inlet 140 is used to introduce the reclaimed water to be settled into the sedimentation tank 1, and the sewage outlet 150 is used to discharge the impurities settled in the sedimentation chamber 4.

[0032] The sedimentation chamber 4 includes a sludge area 410, an inclined plate area 420 and a clean water area 430 arranged from bottom to top. The reclaimed water from the buffer chamber 3 enters the sludge area 410 and is precipitated in the sludge area 410. As the liquid level in the sludge area 410 continues to rise to the inclined plate area 420, fine silt and other solid impurities contained in the reclaimed water are precipitated on multiple inclined plates 421 of the inclined plate area 420. The impurities are continuously accumulated on the inclined plates 421, and then fall along the inclined plate surface of the inclined plates 421 to the sludge area 410. The obtained clean water enters the clean water area 430 and overflows out of the sludge area 410 through the overflow port 431, thereby realizing the sedimentation of the reclaimed water and achieving the effect of purifying the reclaimed water.

[0033] The inclined plate area 420 includes a plurality of inclined plates 421 arranged in parallel, an upper connecting rod 422, a lower connecting rod 423 and a telescopic cylinder 440. The inclined plate 421 includes an upper plate body 5 and a lower plate body 6. The upper portion of the upper plate body 5 is connected to the upper connecting rod 422, and the lower portion of the lower plate body 6 is connected to the lower connecting rod 423. The upper connecting rod 422 is used to connect and fix the upper plate bodies 5 of the plurality of inclined plates 421, and the lower connecting rod 423 is used to connect and fix the lower plate bodies 6 of the plurality of inclined plates 421. The output end of the telescopic cylinder 440 is connected to the bottom of the lower connecting rod 423. The arrangement of the inclined plate 421 increases the sedimentation space, effectively utilizes the space of the sedimentation chamber 4, and enhances the sedimentation effect.

[0034] The telescopic cylinder 440 is a waterproof telescopic cylinder, and further, a telescopic material is wrapped around the outer side of the telescopic cylinder 440 located in the sludge area 410 to prevent sludge impurities from entering the telescopic cylinder. For example, the telescopic material is a corrugated tube with a wrinkled surface.

[0035] Since the upper plate 5 is sleeved on the outside of the lower plate 6 through the groove 510, when the telescopic cylinder 440 drives the lower plate 6 to rise or fall by driving the lower connecting rod 423, the side wall of the upper plate 5 and the side wall of the lower plate 6 move relative to each other, so that the side wall of the upper plate 5 scrapes the impurities settled on the outer wall of the lower plate 6, thereby achieving the effect of removing the impurities on the outer wall of the lower plate 6. In this way, after a long period of sedimentation, by starting the telescopic cylinder 440 to telescope, the upper plate 5 and the lower plate 6 move relative to each other, thereby removing the impurities on the outer wall of the lower plate 6, without draining the water in the sedimentation tank 1, stopping the sedimentation, and then taking out the inclined plate 421 for cleaning. The setting of the present application can realize the regular cleaning of impurities on the inclined plate 421 during the sedimentation process by timing the telescopic cylinder 440, which greatly reduces the time used to clean the inclined plate 421 and improves the sedimentation efficiency of the water.

[0036] A groove 510 is opened inside the upper plate body 5, and a part of the lower plate body 6 extends into the groove 510, and a spring 511 is arranged in the groove 510. The spring 511 is used to provide elastic deformation and buffering when relative movement occurs between the upper plate body 5 and the lower plate body 6, and maintain a certain tension between the upper plate body 5 and the lower plate body 6, which helps to stably connect the inclined plate 421 with the upper connecting rod 422 and the lower connecting rod 423.

[0037] Furthermore, if the spring 511 is stretched to the maximum extent, a portion of the lower plate body 6 still extends into the groove 510 inside the upper plate body 5. This can prevent the top of the lower plate body 6 from detaching from the groove 510 and separating when relative movement occurs between the upper plate body 5 and the lower plate body 6 during the cleaning process of the inclined plate 421, thereby ensuring the stable operation of the sedimentation device.

[0038] The present application achieves the purpose of regularly cleaning the impurities on the surface of the inclined plate without removing the inclined plate through the above scheme, thereby improving the sedimentation efficiency. By setting a mixing chamber, the reclaimed water and the reagent are mixed for flocculation to form impurities with larger particle sizes. By setting a buffer chamber, the flow of the reclaimed water tends to be stable. By setting an inclined plate area in the sedimentation chamber, the sedimentation space is increased, the space of the sedimentation chamber is effectively utilized, and the sedimentation effect is enhanced. The inclined plate is set to include an upper plate body and a lower plate body. The upper plate body is sleeved on the outside of the lower plate body through a groove. A spring is set in the groove. The telescopic cylinder is extended to drive the lower connecting rod to rise or fall, and then the lower connecting rod drives the lower plate body to move, realizing the relative movement between the upper plate body and the lower plate body, so that the side wall of the upper plate body scrapes off the impurities settled on the outer wall of the lower plate body, thereby achieving the effect of removing impurities on the outer wall of the lower plate body. There is no need to drain the water in the sedimentation tank, stop sedimentation, and then take out the inclined plate for cleaning. The setting of the present application can realize regular cleaning of impurities on the inclined plate during the sedimentation process by regularly opening the telescopic cylinder, which greatly reduces the time used for cleaning the inclined plate, improves the sedimentation efficiency of the grey water, and increases the processing capacity of the grey water.

[0039] like Figure 4 As shown, optionally, an upper hole body 520 is opened on the top of the upper plate body 5, and a lower hole body 610 is opened on the bottom of the lower plate body 6, the upper connecting rod 422 passes through the upper hole body 520, and the lower connecting rod 423 passes through the lower hole body 610, the upper connecting rod 422 and the lower connecting rod 423 are horizontally arranged up and down, and the ends of the upper connecting rod 422 and the lower connecting rod 423 close to the third partition 130 are connected to the side wall of the third partition 130, and the ends of the upper connecting rod 422 and the lower connecting rod 423 away from the third partition 130 are connected to the side wall of the sedimentation tank 1.

[0040] Specifically, the upper connecting rod 422 passes through the upper holes 520 of multiple upper plate bodies 5, and the lower connecting rod 423 passes through the lower holes 610 on multiple lower plate bodies 6, and the inclined plate 421 is fixed between the upper connecting rod 422 and the lower connecting rod 423. The upper connecting rod 422 and the lower connecting rod 423 are horizontally arranged up and down, so that after the reclaimed water enters the inclined plate area 420 from the sludge area 410, the sedimentation on each inclined plate 421 can be synchronized. If the upper connecting rod 422 and the lower connecting rod 423 are inclined, there will be more sediment on the inclined plate 421 at the end of the lower connecting rod 423 that is inclined downward. As the sedimentation proceeds, more impurities are settled on the local inclined plate 421, resulting in uneven load and deviation of the lower connecting rod 423, which is not conducive to the stability of the inclined plate area 420.

[0041] like Figure 5As shown, optionally, a first sliding groove 131 is provided on a side wall where the third partition 130 is connected to the upper connecting rod 422 and the lower connecting rod 423, and a second sliding groove 132 is provided on the side wall where the sedimentation tank 1 is connected to the upper connecting rod 422 and the lower connecting rod 423, and both ends of the lower connecting rod 423 are respectively located in the first sliding groove 131 and the second sliding groove 132.

[0042] Specifically, a first sliding groove 131 is provided on a side wall where the third partition 130 is connected to the upper connecting rod 422 and the lower connecting rod 423, and a second sliding groove 132 is provided on the side wall where the sedimentation tank 1 is connected to the upper connecting rod 422 and the lower connecting rod 423, so that when the telescopic cylinder 440 telescopes and drives the lower connecting rod 423 to rise or fall, the two ends of the lower connecting rod 423 can slide in the first sliding groove 131 and the second sliding groove 132, so that the movement trajectory of the lower connecting rod 423 can be limited, so that the lower connecting rod 423 will not slide at positions other than the first sliding groove 131 and the second sliding groove 132, which is beneficial to the stable relative movement between the upper plate body 5 and the lower plate body 6, and further beneficial to the stability of the inclined plate area 420, so that the inclined plate area 420 maintains the characteristics of stable and efficient sedimentation of the middle water.

[0043] like Figure 3 As shown, optionally, a sloped scraper 530 is provided at the bottom of the side wall of the upper plate body 5 , one end of the sloped scraper 530 is connected to the bottom of the side wall of the upper plate body 5 , and the other end of the sloped scraper 530 abuts against the lower plate body 6 .

[0044] Specifically, one end of the inclined scraper 530 is connected to the bottom of the side wall of the upper plate body 5, and the other end of the inclined scraper 530 abuts against the lower plate body 6. When relative movement occurs between the side wall of the upper plate body 5 and the side wall of the lower plate body 6, the end of the inclined scraper 530 abutting against the surface of the lower plate body 6 scrapes away impurities accumulated on the surface of the lower plate body 6, thereby improving the cleaning ability of the surface of the lower plate body 6, and further facilitating the subsequent efficient sedimentation.

[0045] like Figure 6 As shown, optionally, a medicine inlet 160 is provided at the top of the mixing chamber 2 , and a stirring unit is provided in the mixing chamber 2 .

[0046] The stirring unit includes a motor 710 , a stirring shaft 720 and a stirring paddle 730 which are connected in sequence, and the stirring shaft 720 vertically extends into the interior of the mixing chamber 2 .

[0047] Specifically, the reagent inlet 160 is used to add reagents, such as coagulants, flocculants, etc., to the reclaimed water in the mixing chamber 2 to flocculate impurities such as suspended matter in the reclaimed water, so as to facilitate the sedimentation of impurities under the action of gravity. The stirring unit can improve the mixing efficiency of the reagent and the reclaimed water. The output end of the motor 710 drives the stirring shaft 720 to rotate, and the stirring shaft 720 drives the stirring paddle 730 to rotate, and then the stirring paddle 730 can drive the mixing of the reclaimed water and the reagent to improve the flocculation efficiency.

[0048] like Figure 6 As shown, optionally, the sewage outlet 150 is connected to a sludge pump 8 .

[0049] Specifically, the sludge pump 8 is used to extract the impurities settled in the sludge area 410 through the sewage outlet 150 to avoid excessive settled sludge occupying the space of the sludge area 410, to facilitate the subsequent entry of reclaimed water, and to improve the settling efficiency of the reclaimed water.

[0050] Optionally, at least two springs 511 are provided.

[0051] Specifically, when the upper plate 5 and the lower plate 6 move relative to each other, the top of the lower plate 6 and the top of the groove 510 are evenly stressed, thereby maintaining stable relative movement between the upper plate 5 and the lower plate 6. Furthermore, the number of springs 511 is set according to actual working conditions, and the springs 511 are arranged at equal intervals to ensure stability between the upper plate 5 and the lower plate 6.

[0052] The technical solution of the present application is described in detail below with reference to specific embodiments.

[0053] The operation flow of the reclaimed water sedimentation device of this embodiment during specific operation is as follows:

[0054] The reclaimed water to be settled is introduced into the mixing chamber 2 through the water inlet 140, and at the same time, chemicals such as coagulants, flocculants, etc. are added to the reclaimed water in the mixing chamber 2 through the chemical inlet 160, and the motor 710 is turned on. The output end of the motor 710 drives the stirring shaft 720 to rotate, and the stirring shaft 720 drives the stirring paddle 730 to rotate, so that the stirring paddle 730 can stir the chemical and the reclaimed water, thereby improving the mixing of the reclaimed water and the chemical.

[0055] The medium water containing the reagent flows through the buffer chamber 3, so that the flow of the medium water tends to be stable. The medium water from the buffer chamber 3 flows to the sedimentation chamber 4 through the lower channel of the buffer chamber 3, and the medium water containing the reagent is precipitated under the action of gravity. The medium water from the buffer chamber 3 enters the sludge area 410 and is precipitated in the sludge area 410. As the liquid level of the sludge area 410 continues to rise to the inclined plate area 420, the fine silt and other solid impurities contained in the medium water are precipitated on the multiple inclined plates 421 of the inclined plate area 420. The impurities are continuously accumulated on the inclined plates 421, and then fall to the sludge area 410 along the inclined plate surface of the inclined plates 421. The obtained clean water enters the clean water area 430 and overflows out of the sludge area 410 through the overflow port 431. The impurities settled in the sludge area 410 are discharged through the sewage outlet 150 under the suction force of the sludge pump 8. The sedimentation of the medium water is achieved, and the purification of the medium water is achieved.

[0056] When it is necessary to clean the impurities accumulated on the inclined plate 421, the telescopic cylinder 440 is opened to extend and retract, thereby driving the lower connecting rod 423 to rise or fall, so that the lower connecting rod 423 drives the lower plate body 6 to move. Since the upper plate body 5 is sleeved on the outside of the lower plate body 6 through the groove 510, a spring 511 is arranged in the groove 510. The spring 511 is used to provide elastic deformation when relative movement occurs between the upper plate body 5 and the lower plate body 6, so that relative movement occurs between the side wall of the upper plate body 5 and the side wall of the lower plate body 6, so that the inclined scraper 530 connected to the side wall of the upper plate body 5 and the end that abuts against the surface of the lower plate body 6 scrapes off the impurities accumulated on the surface of the lower plate body 6, thereby achieving the effect of removing impurities on the outer wall of the lower plate body 6.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
