Detailed Implementation

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1-2This invention provides a rotary wastewater treatment device based on automatic sludge discharge, comprising: a fixed component, a rotary filter component, a power component, and a sludge collection box 501. Several sets of rotary filter components are evenly distributed around the fixed component. The power component is mounted on the fixed component and connected to the rotary filter components. The sludge collection box 501 is located below the rotary filter components. Driven by the power component, the rotary filter components rotate around the fixed component, allowing impurities on the rotary filter components to be collected in the sludge collection box 501. Compared to traditional methods, this method is simpler to operate and has a better collection effect, making it suitable for filtering and separating impurities in wastewater during wastewater treatment, preventing impurities in wastewater from clogging drainage pipes.

[0027] In one technical solution of the present invention, eight rotating filter components are evenly distributed around the fixed component, and the central angle of each rotating filter component is 41~43°. The gap between adjacent rotating filter components is small, so that sewage can be filtered through the rotating filter components. It has the advantages of simple structure and good sewage treatment effect.

[0028] The fixing component in this invention includes a central fixing shaft 101 and a spiral support platform 102, the spiral support platform 102 being sleeved and fixed on the central fixing shaft 101. Figure 3 The coordinates of any cross-sectional profile of the spiral support platform 102 ( x, y )satisfy:

[0029]

[0030] in, To bypass x The axis rotates counterclockwise by an angle, R is the maximum radius on the selected cross-section, and r is the radius of the hollow cylinder of the helical support platform.

[0031] Spiral support platform 102 At this point, the radius of the spiral support platform 102 abruptly decreases from its maximum radius R to its minimum radius r, causing the second connecting rod 208 in the rotating filter assembly to lose the support of the spiral support platform 102. The first connecting rod 206, pushed upwards by the control spring 201, causes the corresponding filter blade 203 to fall due to the loss of support from the first connecting rod 206. This results in the filter blade 203 sliding down, making it easier for wastewater impurities to slide off. Therefore, at the spiral support platform 102... A residue collection box 501 is installed below the rotating filter assembly to facilitate the collection of wastewater impurities that fall from the rotating filter assembly; a spiral support platform 102 At this point, the radius of the spiral support platform 102 increases from r to R, which expands the second connecting rod 208, causing the first connecting rod 206 to support the filter screen blades 203 to a horizontal position, facilitating wastewater filtration. Therefore, at the spiral support platform 102... The upper sewage pipe 401 is arranged above the rotating filtering assembly, so that the sewage flowing out of the upper sewage pipe 401 can be filtered through the horizontally arranged filter blade 203.

[0032] As Figure 4 Each rotating filtering assembly comprises a control spring 201, an arc-shaped hinge 202, a filter blade 203, a water baffle 204, a connecting hinge 205, a first connecting rod 206, a limited rotation angle hinge 207, a second connecting rod 208, a push rod 209 and a spring shell 210. Figure 5 The arc-shaped hinge 202 is fixedly connected with the outer wall of the first ball bearing, and the inner wall of the first ball bearing is welded on the outer surface of the central fixed shaft 101, so that the filter blade 203 can rotate up and down around the arc-shaped hinge 202; the water baffle 204 is arranged on the filter blade 203, the filter blade 203 outside the water baffle 204 is a filter structure for intercepting impurities in the sewage, the lower end of the filter blade 203 is connected with one end of the first connecting rod 206 through the hinge 205, so that the first connecting rod 206 can rotate around the hinge 205, and the hinge 205 and the water baffle 204 are located on the same vertical line; the other end of the first connecting rod 206 is connected with one end of the second connecting rod 208 through the limited rotation angle hinge 207, the other end of the second connecting rod 208 is connected with one end of the push rod 209 through the hinge, and the second connecting rod 208 is slidingly connected with the side wall of the spiral support table 102; the push rod 209 is arranged in the spring shell 210, the push rod 209 is limited to move only up and down by the spring shell 210, the other end of the push rod 209 is fixedly connected with the upper end of the control spring 201, and the bottom of the control spring 201 is fixedly connected with the bottom in the spring shell 210. The lower sewage pipe 403 with the gradually expanding pipe opening 402 is arranged below the corresponding filter blade 203 of the upper sewage pipe 401, and the water filtered through the filter blade and the splashed water drops are collected through the gradually expanding pipe opening 402.

[0033] The power assembly comprises a ball bearing extension shell 301, a first variable direction gear 302, a second variable direction gear 303 and a motor 304.

[0034] As Figure 6The diagram illustrates the working state of the filter blades. The working process of the rotary wastewater treatment device based on automatic sludge removal of this invention is as follows: When the rotary filter assembly rotates slowly under the drive of the motor 304, when the filter blades 203 rotate to directly below the upper drain pipe 401, the rotation angle of the spiral support platform 102 is 0 degrees, and the radius of the spiral support platform is R. This allows the second connecting rod 208 to slide to this position, where it is in a supported state. At this time, the state of the arc-shaped hinge 202 is as follows: Figure 5 In the closed state, supported by the spiral support platform 102, the second connecting rod 208 drives the first connecting rod 206 to support the filter screen blades 203 to a horizontal state. Simultaneously, the control spring 201 is compressed, keeping the filter screen blades 203 horizontal. Wastewater impurities are intercepted by the filter screen blades 203 and remain on them. When the filter screen blades 203 rotate above the residue collection box 501, the rotation angle of the spiral support platform 102 at this point is... That is, falling from the point of maximum radius to the point of minimum radius, at which point the curved hinge 202 is in the following state: Figure 5 When b is in the open state, the second link 208 loses the support of the spiral support platform 102, and the control spring 201 releases and pushes it upward. At the same time, the filter blade 203 loses the support of the first link 206 and rotates around the arc hinge 202 to the lowest position, causing impurities to slide into the residue collection box 501. Subsequently, during the rotation of the filter rotating assembly, the second link 208 is gradually opened along the side wall of the spiral support platform 102, and the filter blade 203 gradually returns to the horizontal position.

[0035] This invention relates to a rotary wastewater treatment device with automatic sludge discharge. The device uses rotating filter blades to circulate and filter wastewater, intercepting impurities. The rotation cycle of the rotating filter is adjusted by controlling the motor speed, thus controlling the frequency at which the filter impeller empties the wastewater impurities into the residue collection box. Operators only need to periodically collect and clean the residue from the collection box. This rotary wastewater treatment device is characterized by its simple operation, environmental friendliness, and labor savings.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should be considered within the scope of protection of the present invention.
