Description

Technical Field

[0001] This utility model relates to the field of sludge thickening technology, and in particular to a high-efficiency cyclone sludge thickening tank device. Background Technology

[0002] Sludge sedimentation and thickening are both effective methods to reduce sludge moisture content and sludge volume. Sludge sedimentation and thickening mainly reduce the water content in sludge. After thickening, the sludge is similar to a paste, but still retains fluidity. Sludge thickening can effectively reduce the water content of sludge discharged from water treatment structures. This method is suitable for treating sludge with high water content.

[0003] Gravity thickening is the most commonly used method for sludge thickening. Gravity thickening uses sludge thickening tanks, which can be continuous or intermittent. In the thickening tank, solid particles in the sludge will sink under the action of gravity, and the water in the sludge will be squeezed out. The thickened sludge is discharged from the bottom of the thickening tank, and the muddy water overflows from the weir on the surface of the thickening tank or flows out from the outlet on the side of the thickening tank. Thickening tanks with this structure generally have the disadvantages of large volume, long retention time, inconvenient operation and high energy consumption, and the efficiency of sludge thickening is relatively low.

[0004] Chinese Patent Publication No. CN205307900U discloses a high-efficiency cyclone sludge settling and thickening tank, which includes a tank body and a fixing frame. The tank body is supported and fixed by the fixing frame. A hydrocyclone, a sludge scraper, and a co-current flow inclined plate are installed inside the tank body. A tangential water inlet and a water outlet are located on the upper part of the tank body. A stainless steel hydrocyclone and a fiberglass co-current flow inclined plate are installed in the middle of the tank body. The fiberglass co-current flow inclined plate is installed at a certain angle around the hydrocyclone. A sludge scraper is installed along the bottom of the tank body. The sludge scraping device includes a rotating shaft and a sludge discharge port at the lower end of the tank bottom. This high-efficiency cyclone sludge settling and thickening tank is a center-driven, continuous or intermittent thickening and clarification device. Through the combined action of the hydrocyclone and the co-directional inclined flow plate, it can greatly improve the flow and distribution characteristics of sludge in the thickening tank, increase its volume utilization coefficient, shorten the settling path of fine particles, accelerate the settling opportunity of fine particles, improve settling efficiency, and increase the effective settling area by several times. The sludge treatment capacity of the equipment can be increased by 3 to 6 times.

[0005] The aforementioned device uses hydrocyclones to accelerate the sedimentation and concentration of sludge, but it lacks a structure for treating the water in the sludge discharged from the hydrocyclone through the overflow port. The water in the sludge discharged from the hydrocyclone is not entirely clean. When the water in the sludge discharged from the hydrocyclone is discharged directly without treatment, it can easily cause environmental pollution. Utility Model Content

[0006] The main purpose of this invention is to provide a high-efficiency cyclone sludge thickening tank device, which can effectively solve the problem that the water separated from the sludge during sludge thickening is discharged directly without being filtered, which easily causes environmental pollution.

A connecting ring one and a connecting ring two are installed in the middle of the rotating rod. Several scraper assemblies arranged circumferentially around the central axis of the rotating rod are installed between the connecting ring one and the connecting ring two.

[0010] Preferably, the scraper assembly includes a connecting plate and a scraper.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 and Figure 2 As shown, a high-efficiency hydrocyclone sludge thickening tank device includes a hydrocyclone 1, an outer casing 2 installed on the outside of the hydrocyclone 1, a perforated outer casing 3 fixedly connected to the lower end of the outer casing 2, a cleaning component 4 installed inside the perforated outer casing 3, a sludge discharge component 5 installed at the lower opening of the perforated outer casing 3, and support legs 6 fixedly connected to the four corners of the lower end of the perforated outer casing 3. A filter component 7 connected to the hydrocyclone 1 is installed on the side of the outer casing 2.

[0026] The aforementioned hydrocyclone 1 is composed of a feed pipe, an overflow pipe, a cylinder, a cone, a cyclone chamber, a liquid-solid separation zone, and a settling nozzle. Its working principle is based on the centrifugal sedimentation principle, that is, suspended particles are subjected to centrifugal force in a rotating fluid and undergo sedimentation and classification. When the fluid enters the cyclone chamber through the feed pipe, it generates a high-speed rotating vortex under the guidance of the cyclone core tube. The solid particles in the vortex are pushed against the wall of the hydrocyclone by centrifugal force to form an annular accumulation layer. At the same time, the liquid is subjected to centripetal force and moves towards the center of the hydrocyclone to form an internal vortex from bottom to top, which is eventually discharged through the overflow pipe. The solid particles move downward along the wall of the hydrocyclone and are eventually discharged through the underflow pipe. This is a mature technology in the prior art, and its structure and working principle will not be elaborated further in this solution.

[0027] In specific implementation, sludge with high water content is transported into hydrocyclone 1 through the feed pipe of hydrocyclone 1. Under the action of hydrocyclone 1, the sludge part in the sludge will be discharged downward by hydrocyclone 1 from the sand discharge nozzle into the hole shell 3. The water separated from the sludge will be discharged upward through the overflow pipe into the filter assembly 7. The filter assembly 7 will filter the water coming out of the sludge.

[0028] The cleaning component 4 and the mud discharge component 5 are activated. The cleaning component 4 scrapes the mud adhering to the inner wall of the hole shell 3 that has entered the hole shell 3, preventing the mud from accumulating inside the hole shell 3. The mud is discharged by activating the mud discharge component 5.

[0029] Specifically, in order to save sludge settling and coagulation time and improve sludge thickening efficiency, refer to... Figure 3 The cleaning component 4 includes a fixed plate 41 and a support plate 42. Both the fixed plate 41 and the support plate 42 are installed in the inner cavity of the hole shell 3. The support plate 42 is located on the upper side of the fixed plate 41. A motor 43 and a cylinder 44 covering the outside of the motor 43 are installed on the upper end of the fixed plate 41. The output end of the motor 43 is fixedly connected to a rotating rod 45 through a coupling. The upper end of the rotating rod 45 passes through the cylinder 44 and is rotatably connected to the support plate 42. A connecting ring 1 46 and a connecting ring 2 47 distributed vertically are installed in the middle of the rotating rod 45. Several scraper components 48 arranged circumferentially around the central axis of the rotating rod 45 are installed between the connecting ring 1 46 and the connecting ring 2 47.

[0030] Further reading Figure 4 The scraper assembly 48 includes a connecting plate 481 and a scraper 484. The inner end of the connecting plate 481 is fixedly connected to the outer ends of the first connecting ring 46 and the second connecting ring 47, respectively. The scraper 484 is located outside the connecting plate 481, and a plurality of telescopic rods 483 are installed between the scraper 484 and the connecting plate 481. Springs 482 are sleeved on the outside of the telescopic rods 483, and the two ends of the springs 482 are fixedly connected to the connecting plate 481 and the scraper 484, respectively.

[0031] Further reading Figure 6 The mud discharge assembly 5 includes a mud discharge pipe 1 51, which is installed at the lower opening of the hole housing 3. A mud discharge valve 52 is fixedly connected to the lower end of the mud discharge pipe 1 51, and a mud discharge pipe 2 53 is fixedly connected to the lower end of the mud discharge valve 52.

[0032] The aforementioned sludge discharge valve 52 is composed of a valve body, hydraulic cylinder, piston, valve stem, and valve disc. It typically adopts a quick-opening and closing design, which can quickly discharge sludge, sand, dirt, and impurities from the bottom of the sedimentation tank or water tank in a short time, thereby improving sludge discharge efficiency. Its valve disc and valve body are reasonably designed to effectively prevent sludge and dirt from clogging the valve and ensure the smooth progress of the sludge discharge process. It is a mature technical means in the existing technology, and its structure and working principle will not be elaborated further in this solution.

[0033] In specific implementation, sludge with high water content is transported into hydrocyclone 1 through the feed pipe of hydrocyclone 1. Under the action of hydrocyclone 1, the sludge part in the sludge will be discharged downward by hydrocyclone 1 from the sand discharge nozzle into the hole shell 3.

[0034] When the motor 43 and the mud discharge valve 52 are turned on, the motor 43 drives the rotating rod 45 to rotate, which in turn drives the connecting ring 46 and the connecting ring 47 to rotate, which in turn drives the connecting plate 481 to rotate. The support plate 42 can act as a retainer, making the process of the rotating rod 45 rotating, driving the connecting ring 46 and the connecting ring 47 to rotate, and thus driving the connecting plate 481 to rotate more stable.

[0035] The connecting plate 481 rotates, which drives the scraper 484 to rotate to scrape and remove the sludge adhering to the inner wall of the hole shell 3, preventing the sludge from accumulating in the hole shell 3 and causing blockage, so that the sludge cannot be smoothly discharged from the hole shell 3 through the sludge discharge component 5.

[0036] The outer wall of the scraper 484 is in close contact with the inner wall of the hole housing 3. At this time, the springs 482 are in a compressed state. Under the reaction of the springs 482, the scraper 484 exerts a greater scraping force on the inner wall of the hole housing 3, thereby improving the scraping effect of the scraper 484 on the sludge on the inner wall of the hole housing 3.

[0037] Specifically, in order to treat the water in the sludge discharged from the hydrocyclone 1 through the overflow pipe and prevent the water separated from the sludge from being directly discharged into the external environment, which could easily cause environmental pollution, please refer to... Figure 5 The filter assembly 7 includes a water tank 72, which is fixedly connected to the left end of the outer casing 2. A connecting pipe 71 connected to the overflow pipe of the hydrocyclone 1 is installed on the upper end of the water tank 72. A diversion assembly 73 and two filter plates 74 located on the lower side of the diversion assembly 73 are installed inside the water tank 72. A water outlet pipe 75 is fixedly connected to the lower end of the water tank 72. The diversion assembly 73 includes a rectangular plate 731, which is installed inside the water tank 72 and located on the upper side of the filter plates 74. Several round holes 732 are opened in the middle of the upper end of the rectangular plate 731.

[0038] The aforementioned water outlet fitting 75 consists of two water outlet circular pipes and a sludge discharge valve;

[0039] Both filter plates 74 mentioned above are made of fiber, activated carbon, ceramic or other specific materials as filter media. The main function of the disperser is to provide a uniform water flow to the filter media, ensuring that the filter media can be fully exposed in the water flow, thereby achieving the best filtration effect. The water collection pipe is located at the bottom of the filter plate and is responsible for collecting the impurities and solid particles removed after passing through the filter media and discharging them from the equipment to prevent clogging and ensure the normal operation of the equipment. It is a mature technical means in the prior art, and its structure and working principle will not be elaborated on here.

[0040] In practice, when the outlet pipe 75 is opened, the water separated from the sludge is discharged through the overflow pipe of the hydrocyclone 1 and further enters the water tank 72 through the connecting pipe 71. The space between the upper surface of the inner surface of the water tank 72 and the upper end of the rectangular plate 731 flows through the round hole 732 to the filter plate 74 located below. The round hole 732 allows the water separated from the sludge to be evenly distributed in the filter plate 74, thereby increasing the contact area between the water separated from the sludge and the filter plate 74 and improving the filtration effect of the filter plate 74 on the water separated from the sludge.

[0041] The water separated from the sludge will pass through two filter plates 74 in sequence. The filter plates 74 will filter out impurities and pollutants in the water separated from the sludge, preventing the water separated from unclean sludge from being discharged directly into the external environment without treatment, which could easily cause pollution to the external environment and clean water sources.

[0042] It should be noted that the specific installation method, circuit connection method, and control method of the hydrocyclone 1 and motor 43 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0043] The working principle of this utility model is as follows:

[0044] Sludge with high water content is fed into hydrocyclone 1 through the feed pipe. Under the action of hydrocyclone 1, the sludge part of the sludge will be discharged downward by hydrocyclone 1 from the sand discharge nozzle into the hole shell 3.

[0045] Turn on the motor 43 and the mud discharge valve 52. The motor 43 turns on and drives the rotating rod 45 to rotate, which in turn drives the connecting ring 46 and the connecting ring 47 to rotate, which in turn drives the connecting plate 481 to rotate, which in turn drives the scraper 484 to rotate and scrape and remove the sludge adhering to the inner wall of the hole shell 3. The sludge is discharged from the hole shell 3 through the mud discharge assembly 5.

[0046] The water separated from the sludge is discharged through the overflow pipe of the hydrocyclone 1 and then enters the water tank 72 through the connecting pipe 71. When the outlet pipe 75 is opened, the water separated from the sludge passes through two filter plates 74 in sequence. The filter plates 74 filter the impurities and pollutants in the water separated from the sludge. Then the filtered water is discharged through the outlet pipe 75.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
