Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of sewage treatment devices, in particular to a high-efficiency mixing device based on an inclined stirring barrel. BACKGROUND

[0002] In the field of sewage treatment and material mixing, the efficiency of the mixing device directly determines the treatment effect and production efficiency. The inclined stirring barrel, as a commonly used device, is often applied to the preliminary treatment or pretreatment link of sewage. Its core function is to achieve solid-liquid mixing through stirring to create conditions for microorganisms to decompose pollutants.

[0003] However, there are generally impurities with large particle sizes in sewage, such as suspended solids, fibrous substances, sand, and organic debris. These impurities are easily deposited at the bottom of the stirring barrel due to gravity, forming a dense impurity layer. The traditional stirring method only generates vortex through the rotation of mechanical stirring blades, which is difficult to completely break the deposition state of impurities, resulting in limited contact area between microorganisms and impurities, significantly prolonging the decomposition process. Especially when treating high-solid-content sewage, more time is often needed for reaction.

[0004] Therefore, the existing device often sets multiple filter screens in the barrel to uniformly distribute impurities, and then the decomposed impurities are discharged to the bottom through the filter holes. However, this method also has the problem that impurities are accumulated together, making it difficult for microorganisms to fully contact and decompose the accumulated impurities, which seriously affects the efficiency and effectiveness of sewage purification treatment. It cannot meet the increasingly strict environmental protection requirements and actual treatment needs, and has certain deficiencies. SUMMARY

[0020] Further, the upper chamber in the piston cylinder is connected with a spring member, and the spring member is used for continuously moving the top rod reciprocatingly in the piston cylinder.

[0021] Further, the liquid discharge pipe is a metal pipe.

[0022] Compared with the prior art, the present application has the following beneficial effects: through the arrangement of the arc-shaped plate, the rotating filter plate can continuously move up and down reciprocatingly, thereby continuously disturbing the liquid in the tank, making the liquid flow uniformly, facilitating the treatment of the sewage by the microorganisms, and at the same time, the impurities left on the filter screen can be ground and crushed, facilitating the decomposition and treatment of the impurities by the microorganisms.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but not to limit the scope of the present application.

[0034] Embodiment 1

[0035] Reference Figures 1-8 A high-efficiency mixing device based on an inclined stirring barrel, comprising a tank body 1, further comprising: a rotating shaft 302 rotatably connected in the tank body 1; an arc plate 2 fixedly connected in the tank body 1; a plurality of piston cylinders 4 each fixedly connected in the rotating shaft 302, a piston cylinder 4 having an ejector rod 404 rotatably connected at the telescopic end thereof, one end of the ejector rod 404 abutting against the arc plate 2; a plurality of filter screens 304 each fixedly connected on the rotating shaft 302 at equal intervals; a plurality of rotating filter plates 6 each fixedly connected on the ejector rod 404 at equal intervals; through rotation of the rotating shaft 302, the ejector rod 404 is continuously moved up and down along the arc surface of the arc plate 2, and the rotating filter plate 6 is continuously reciprocated up and down, and the rotating filter plate 6 is continuously switched between close to and away from the filter screen 304, through the rotating filter plate 6 close to the filter screen 304, the impurities on the filter screen 304 can be ground and crushed, facilitating decomposition of the impurities by microorganisms; the tank body 1 is provided with a liquid inlet pipe 101 and a liquid outlet pipe 102, the tank body 1 is fixedly connected with a motor 301, the output end of the motor 301 is fixedly connected with the rotating shaft 302, a plurality of mounting plates 303 are fixedly connected on the rotating shaft 302, and the mounting plates 303 are used for mounting the piston cylinders 4.

[0036] The up-and-down movement of the top rod 404 directly drives the synchronous movement of the rotating filter plate 6 fixed on the side thereof: when the top rod 404 moves upward, the rotating filter plate 6 is close to the upper layer filter screen 304, and the spacing between the plate surface of the rotating filter plate 6 and the filter screen 304 is reduced, at this time, the rotating filter plate 6 generates extrusion and grinding force on the impurities (such as fibers and particulate pollutants) intercepted on the filter screen according to the rotational inertia of the top rod 404, and the impurities are crushed through the toothed structure (or rough surface) of the plate surface; when the top rod 404 moves downward, the rotating filter plate 6 is away from the filter screen 304, and space is left for the subsequent liquid flow, in this process, the up-and-down reciprocating movement of the rotating filter plate 6 not only continuously grinds the impurities on the filter screen 304, but also forms vortex flow by agitating the liquid, so that the liquid (containing microbial agents) in the tank 1 is mixed uniformly, and the contact efficiency of microorganisms and pollutants is significantly improved.

[0037] The motor 301 on the tank 1 is started, and the output end drives the rotating shaft 302 to rotate in the tank 1, when the rotating shaft 302 rotates, the piston cylinder 4 rotates synchronously, and the top rod 404 at the telescopic end of the piston cylinder 4 moves up and down along the arc surface of the arc plate 2, so that the rotating filter plate 6 continuously moves up and down, and switches between approaching and moving away from the filter screen 304, when approaching, the rotating filter plate 6 grinds the impurities on the filter screen 304, facilitating microbial decomposition; at the same time, the liquid in the tank 1 is disturbed, so that it flows uniformly, which is beneficial to microbial treatment of sewage.

[0038] The liquid to be treated is injected into the tank 1 through the liquid inlet pipe 101, and then the liquid containing microorganisms is injected, the motor 301 is started to drive the rotating shaft 302 to rotate, and the piston cylinder 4 and other components on the mounting plate 303 work cooperatively, and the treated liquid is discharged from the liquid outlet pipe 102.

[0039] The filter hole diameters of the multiple groups of filter screens 304 are arranged to decrease in turn from top to bottom, and the filter hole diameters of the rotating filter plate 6 are the same as those of the filter screens 304 and are arranged to decrease in turn from top to bottom.

[0040] After the sewage enters the tank 1, because the filter hole diameters of the multiple groups of filter screens 304 and the rotating filter plate 6 decrease in turn from top to bottom, large-particle impurities are first intercepted by the upper layer filter screen 304 and are ground by the rotating filter plate 6, and small-particle impurities are intercepted and treated by the lower layer filter screen 304, so that the efficiency of impurity treatment and the effect of microbial decomposition are improved.

[0041] The piston cylinder 4 is provided with an arc-shaped groove 405, and the top rod 404 is fixedly connected with a connecting rod 406 which is slidingly connected in the arc-shaped groove 405, through the up-and-down movement of the top rod 404, the top rod 404 rotates along the arc-shaped groove 405, and the rotating filter plate 6 continuously and synchronously moves left and right reciprocatingly when moving up and down.

[0042] When the top rod 404 moves up and down, the connecting rod 406 slides in the arc-shaped slot 405, the top rod 404 rotates along the arc-shaped slot 405, and drives the rotating filter plate 6 to move up and down and reciprocate left and right, which not only strengthens the grinding of impurities on the filter screen 304, but also further disturbs the liquid in the tank 1, so that the mixture is more uniform.

[0043] Embodiment 2:

[0044] With reference to Figures 1-8 An efficient mixing device based on an inclined stirring barrel, which is basically the same as embodiment 1, and further has that the piston cylinder 4 is divided into two chambers by a piston, a liquid suction pipe 401 and a liquid discharge pipe 402 are connected in the lower chamber, the liquid suction pipe 401 faces the bottom of the tank 1, and the liquid discharge pipe 402 is used to discharge the liquid sucked by the liquid suction pipe 401 to the upper end of the tank 1; a one-way valve is connected to each of the liquid suction pipe 401 and the liquid discharge pipe 402.

[0045] When the piston in the piston cylinder 4 moves with the top rod 404, the piston moves downward, and the lower chamber sucks the liquid at the bottom of the tank 1 through the liquid suction pipe 401; when the piston moves upward, the lower chamber discharges the liquid to the upper end of the tank 1 through the liquid discharge pipe 402, so as to realize the circulation of the liquid from the bottom to the top and promote the uniform mixing of the liquid in the tank 1.

[0046] A plurality of piston rods 501 are fixedly connected to the rotating shaft 302, a scraper 502 is fixedly connected to the extension end of each piston rod 501, and the scraper 502 abuts against the filter screen 304. Through the extension of the extension end of the piston rod 501, the scraper 502 can push the impurities on the filter screen 304 to the lower side of the rotating filter plate 6. A gas delivery pipe 403 is connected to the upper chamber in the piston cylinder 4, the gas delivery pipe 403 communicates with the piston rod 501, the piston in the piston cylinder 4 moves up and down driven by the top rod 404, and then the gas in the upper chamber is switched between being discharged into and being sucked from the piston rod 501, so as to make the extension end of the piston rod 501 reciprocate continuously.

[0047] When the piston in the piston cylinder 4 moves up and down driven by the top rod 404, the gas in the upper chamber is switched between being discharged into and being sucked from the piston rod 501 through the gas delivery pipe 403. When the gas is discharged, the extension end of the piston rod 501 extends, and the scraper 502 pushes the impurities; when the gas is sucked, the extension end of the piston rod 501 retracts, and thus the scraper 502 automatically pushes the impurities, which is combined with the treatment of the rotating filter plate 6.

[0048] A spring member 407 is connected to the upper chamber in the piston cylinder 4, and the spring member 407 is used to make the top rod 404 reciprocate continuously in the piston cylinder 4; the liquid discharge pipe 402 is a metal pipe.

[0049] The spring member 407 is in the upper chamber in the piston cylinder 4, and assists the top rod 404 to reset when the top rod 404 moves to change the piston, ensures the stable reciprocating movement of the top rod 404 in the piston cylinder 4, maintains the stable and continuous operation of the device, guarantees the normal work of the rotating filter plate 6 and other components, and the metal pipe of the liquid discharge pipe 402 has a long service life and can play the role of a stirring rod to stir the liquid in the tank body 1.

[0050] That is, in use, the motor 301 on the tank body 1 is started, the output end drives the rotating shaft 302 to rotate in the tank body 1, the piston cylinder 4 rotates synchronously when the rotating shaft 302 rotates, the top rod 404 at the telescopic end of the piston cylinder 4 moves up and down along the arc surface of the arc plate 2, the rotating filter plate 6 moves up and down reciprocatingly, and switches between approaching and moving away from the filter screen 304. When approaching, the rotating filter plate 6 grinds the impurities on the filter screen 304, facilitating the decomposition of microorganisms. At the same time, the liquid in the tank body 1 is disturbed to flow uniformly, which is beneficial to the treatment of sewage by microorganisms. After the sewage enters the tank body 1, because the filter hole diameters of the filter screens 304 and the rotating filter plate 6 gradually decrease from top to bottom, large-particle impurities are first intercepted by the upper filter screen 304 and are ground by the rotating filter plate 6; small-particle impurities are intercepted and treated by the lower filter screen 304, realizing graded filtration and grinding, improving the impurity treatment efficiency and the microorganism decomposition effect. When the top rod 404 moves up and down, the connecting rod 406 slides in the arc-shaped groove 405, the top rod 404 rotates along the arc-shaped groove 405, drives the rotating filter plate 6 to move up and down and reciprocate left and right, which not only strengthens the grinding of the impurities on the filter screen 304, but also further disturbs the liquid in the tank body 1 to make the mixture more uniform. At the same time, the piston moves with the top rod 404, the piston moves downward, the lower chamber sucks the liquid at the bottom of the tank body 1 through the liquid suction pipe 401; the piston moves upward, the lower chamber discharges the liquid to the upper end of the tank body 1 through the liquid discharge pipe 402, realizing the circulation of the liquid from the bottom to the top, promoting the uniform mixing of the liquid in the tank body 1. When the top rod 404 drives the piston in the piston cylinder 4 to move up and down, the gas in the upper chamber switches between being discharged and being sucked by the piston rod 501 through the gas conveying pipe 403. When the gas is discharged, the telescopic end of the piston rod 501 extends, and the scraper 502 pushes the impurities. When the gas is sucked, the telescopic end of the piston rod 501 retracts. In this way, the scraper 502 automatically pushes the impurities, which are treated in cooperation with the rotating filter plate 6.

[0051] The setting of the arc plate 2 can make the rotating filter plate 6 move up and down reciprocatingly, further disturb the liquid in the tank body 1 to make the liquid flow uniformly, facilitate the treatment of sewage by microorganisms, and grind the impurities left on the filter screen 304 while the rotating filter plate 6 moves up and down reciprocatingly, which is convenient for the decomposition and treatment of the impurities by microorganisms.

Although the present application has been disclosed with the preferred embodiments as above, it is not intended to limit the present application, and any skilled person in the art can make some changes or modifications to the above-mentioned technical content with the prompt as equivalent embodiments of equivalent changes without departing from the technical solution of the present application.
