Description

Technical Field

[0001] The present invention belongs to the technical field of wastewater treatment, and in particular relates to an inclined plate sedimentation tank for industrial wastewater treatment. Background Art

[0002] Sedimentation tanks are structures that use sedimentation to remove suspended solids from water and are widely used in wastewater treatment. Sedimentation tanks have a variety of structural forms, among which the inclined plate sedimentation tank can greatly improve sedimentation efficiency, shorten sedimentation time, and reduce the size of the sedimentation tank by adding inclined plates in the tank. However, in general inclined plate sedimentation tanks used for industrial wastewater treatment, the inclined plates are fixed and the inclination angles between the inclined plates cannot be changed, making it difficult to specifically treat sludge in different sewage. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an inclined plate sedimentation tank for industrial wastewater treatment, which can change the inclination angle of the inclined plate. By changing the inclination angle of the inclined plate, the sludge filtration efficiency in different industrial wastewaters can be improved.

[0004] The purpose of this disclosure can be achieved through the following technical solutions:

[0005] An inclined plate sedimentation tank for industrial wastewater treatment, comprising:

[0006] A sedimentation box, wherein one side wall of the sedimentation box is slidably connected with a rack along the length direction of the sedimentation box;

[0007] A plurality of inclined plates are evenly spaced along the length direction of the rack and are distributed inside the sedimentation box. Connecting shafts are fixedly connected on both sides of the inclined plates. A gear is fixedly connected to the connecting shaft on one side of the inclined plates. The gear is meshed with the rack. The connecting shafts on both sides of the inclined plates are rotatably connected to the side walls of the sedimentation box. One of the connecting shafts penetrates the side wall of the sedimentation box and extends outward to be fixedly connected to a connecting rod. The other end of the connecting rod is fixedly connected to a threaded column, and two nuts are threadedly connected to the threaded column.

[0008] The limiting plate is fixedly connected to the outer wall of the sedimentation box, an arc-shaped limiting groove is opened on the limiting plate, the threaded column passes through the arc-shaped limiting groove, and two nuts are distributed on both sides of the limiting plate.

[0009] The above technical solution, its principle and technical effect:

[0010] By rotating the connecting shaft, one of the inclined plates rotates, and the gear connected to it rotates accordingly, which in turn causes the rack to slide. The sliding of the rack drives the remaining gears to rotate, and thus all the inclined plates rotate together. The rotation of the connecting shaft drives the connecting rod to swing, and the connecting rod drives the threaded column to move in the arc-shaped limit groove. When the inclination angle of the inclined plate is adjusted, the two nuts are moved toward each other and tightened to fix the threaded column, thereby fixing the inclined plate.

[0011] In a preferred example, the present invention can be further configured as follows: the end of the connecting shaft connected to the connecting rod is fixedly connected to the output end of the motor.

[0012] In a preferred example, the utility model can be further configured as follows: the motor is fixedly connected to a fixing seat, and the fixing seat is fixedly connected to a side wall of the sedimentation box.

[0013] In a preferred example, the present invention can be further configured as follows: the arc-shaped limiting groove is coaxially arranged with the connecting shaft.

[0014] In a preferred example, the present invention can be further configured as follows: the limiting plate can have scale lines on the side of the arc-shaped limiting groove.

[0015] In a preferred example, the utility model can be further configured as follows: a water inlet is provided at the upper end of one end of the sedimentation box.

[0016] In a preferred example, the utility model can be further configured as follows: a water outlet is provided at the upper end of the other end of the sedimentation box.

[0017] In a preferred example, the utility model can be further configured as follows: a sewage outlet is provided at the lower end of the sedimentation tank at the same end as the water outlet.

[0018] In a preferred example, the utility model can be further configured as follows: a groove plate is fixedly connected to the inner wall of the sedimentation box, and the rack is slidably connected in a slide groove on the groove plate.

[0019] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0020] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0021] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0022] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).

[0023] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded parts of the connected parts).

[0024] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0025] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0026] Beneficial effects of the present disclosure:

[0027] The inclination angle of the inclined plate can be changed, and the sludge filtering efficiency in different industrial wastewaters can be improved by changing the inclination angle of the inclined plate. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0034] In the description of the present disclosure, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limitations on the present disclosure.

[0035] According to the concept of this application, Figures 1 to 4To describe an embodiment of an inclined plate sedimentation tank for industrial wastewater treatment. Specifically, the inclined plate sedimentation tank for industrial wastewater treatment is constructed as a split structure, which has a sedimentation box 1, a rack 2, an inclined plate 3, a gear 5 and other structures that cooperate with each other. By rotating the connecting shaft 4, one of the inclined plates 3 is rotated, and the gear 5 connected thereto rotates accordingly, thereby causing the rack 2 to slide, and the sliding of the rack 2 drives the remaining gears 5 to rotate, thereby causing all the inclined plates 3 to rotate together, wherein the rotation of the connecting shaft 4 drives the connecting rod 6 to swing, and the connecting rod 6 drives the threaded column 7 to move in the arc-shaped limit groove 10. When the inclination angle of the inclined plate 3 is adjusted, the two nuts 8 are tightened by moving them toward each other to fix the threaded column 7, thereby fixing the inclined plate 3.

[0036] like Figure 1-4 As shown, an inclined plate sedimentation tank for industrial wastewater treatment comprises:

[0037] A sedimentation box 1, wherein one side wall inside the sedimentation box 1 is slidably connected with a rack 2 along the length direction of the sedimentation box 1;

[0038] A plurality of inclined plates 3 are evenly spaced along the length direction of the rack 2 and are distributed inside the sedimentation box 1. Connecting shafts 4 are fixedly connected to both sides of the inclined plates 3. A gear 5 is fixedly connected to the connecting shaft 4 on one side of the inclined plates 3. The gear 5 is meshed and connected with the rack 2. The connecting shafts 4 on both sides of the inclined plates 3 are rotatably connected to the side wall of the sedimentation box 1. One of the connecting shafts 4 penetrates the side wall of the sedimentation box 1 and extends outward to be fixedly connected to a connecting rod 6. The other end of the connecting rod 6 is fixedly connected to a threaded column 7. Two nuts 8 are threadedly connected to the threaded column 7.

[0039] The limiting plate 9 is fixedly connected to the outer wall of the sedimentation box 1 , and an arc-shaped limiting groove 10 is opened on the limiting plate 9 . The threaded column 7 passes through the arc-shaped limiting groove 10 , and two nuts 8 are distributed on both sides of the limiting plate 9 .

[0040] When in use, one of the inclined plates 3 is rotated by rotating the connecting shaft 4, and the gear 5 connected thereto rotates accordingly, thereby causing the rack 2 to slide. The sliding of the rack 2 drives the remaining gears 5 to rotate, thereby causing all the inclined plates 3 to rotate together. The rotation of the connecting shaft 4 drives the connecting rod 6 to swing, and the connecting rod 6 drives the threaded column 7 to move in the arc-shaped limit groove 10. When the inclination angle of the inclined plate 3 is adjusted, the two nuts 8 are moved toward each other and tightened to fix the threaded column 7, thereby fixing the inclined plate 3.

[0041] A rack is a special gear with teeth distributed on a bar-shaped body. Racks are divided into spur racks and helical racks, which are used in pairs with spur gears and helical gears respectively; the tooth profile of a rack is a straight line rather than an involute (it is a plane for the tooth surface), which is equivalent to a cylindrical gear with an infinite pitch circle radius.

[0042] Gears are mechanical components with teeth on the wheel rim that can continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. At the end of the 19th century, the principle of gear cutting and the special machine tools and tools that use this principle to cut gears appeared one after another. With the development of production, the stability of gear operation has received attention.

[0043] A nut is a part that is screwed together with a bolt or screw for fastening. It is a component that must be used in all manufacturing machinery. It is divided into several types according to the material, such as carbon steel, stainless steel, and non-ferrous metals (such as copper).

[0044] In one embodiment of the present invention, the end of the connecting shaft 4 connected with the connecting rod 6 is fixedly connected to the output end of the motor 11, the motor 11 is fixedly connected to the fixing seat 12, and the fixing seat 12 is fixedly connected to the side wall of the sedimentation box 1. The motor 12 can drive the connecting shaft 4 to rotate, thereby driving the inclined plate 3 to rotate.

[0045] In one embodiment of the present invention, the arc-shaped limiting groove 10 is coaxially arranged with the connecting shaft 4, so as to ensure that there is no motion interference when the connecting shaft 4 moves.

[0046] In one embodiment of the present invention, there may be a scale line on the side of the arc-shaped limiting groove 10 on the limiting plate 9 to show the inclination angle of the inclined plate 3 .

[0047] In one embodiment of the present invention, a water inlet 13 is provided at the upper end of one end of the sedimentation tank 1 for the entry of sewage.

[0048] In one embodiment of the present invention, a water outlet 14 is provided at the upper end of the other end of the sedimentation tank 1 for discharging sewage after sedimentation.

[0049] In one embodiment of the present invention, a sewage outlet 15 is provided at the lower end of the sedimentation tank 1 at the same end as the water outlet 14, for discharging sewage and sludge.

[0050] In one embodiment of the present invention, the inner wall of the sedimentation box 1 is fixedly connected with a groove plate 16, and the rack 2 is slidably connected in a slide groove on the groove plate 16, so as to provide support for the sliding of the rack 2.
