Description

Technical Field

[0001] The invention relates to the technical field of slurry water sand removal, and in particular to an anti-blocking cyclone. Background Art

[0002] As people's environmental awareness gradually increases and the government continues to increase its efforts in environmental protection, the problem of waste pollution in concrete mixing plants has received more and more attention. After the concrete transport truck completes the discharge, there will inevitably be residual material inside. In order to prevent the residual material from solidifying in the concrete transport truck, a large amount of water is required for flushing. The water used for washing contains a large amount of cement, sand and gravel and other insoluble substances. If it is discharged into the river without treatment, it will cause serious pollution and waste a lot of tap water and concrete materials.

[0003] Therefore, under the national policy of actively advocating the construction of environmentally friendly concrete mixing plants, more and more concrete mixing plants are installing sand and gravel separators. The residual material in the concrete truck is washed out and separated by the sand and gravel separator into sand, gravel, and slurry water, which inevitably contains fine sand. Currently, cyclones are often used to remove sand from the slurry water. The sand-containing slurry water enters the cyclone through the feed port set on the cyclone's side wall. The separated fine sand is discharged through the drain port at the bottom of the cyclone. The desanded slurry water overflows through the overflow port at the top of the cyclone, making it easy to store and use in the next round of concrete production.

[0004] However, fine sand easily adheres to the inner wall of the cyclone's discharge outlet and needs to be cleaned regularly, otherwise the cyclone's discharge outlet will be blocked, causing equipment failure.

[0005] The Chinese patent application number CN201711205371.3 provides an anti-blocking cyclone, which automatically clears the discharge port through a high-pressure nozzle with a valve body and an anti-blocking cavity. The principle is that the attachments at the discharge port enter the anti-blocking cavity from the opening. When they accumulate to a certain amount, the valve body is pushed upward, causing the high-pressure nozzle to spray, achieving the effect of automatic cleaning.

[0006] However, this solution requires the installation of multiple high-pressure nozzles around the discharge port, which has redundant structure and poor practicality. In addition, the material discharged through the discharge port actually falls downward at a low speed, making it difficult to enter the anti-blocking cavity from the horizontally arranged opening, and even more difficult to accumulate in the anti-blocking cavity to the top of the valve body to open the nozzle. Therefore, this solution cannot effectively solve the problem of sewage outlet blockage in actual application, and cannot achieve the effect of automatic unblocking of the sewage outlet.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] The embodiment of the present application solves the problem that the sewage outlet of the cyclone is easily blocked by providing an anti-blocking cyclone.

[0029] The technical solution in the embodiments of the present application is to solve the above technical problems, and the overall idea is as follows:

[0030] In the embodiment of the present invention, an outer sleeve integrally formed with the cyclone shell is provided at the sewage outlet, and an inner cylinder freely sliding up and down in the outer sleeve is provided. The outer sleeve is provided with an air jet device, and the air jet port of the air jet device faces the inner wall of the inner cylinder. A slider is provided on the outer wall of the inner cylinder extending outward. An accommodating cavity is provided on the inner wall of the outer sleeve. A spring is provided between the lower surface of the slider and the bottom surface of the accommodating cavity to prevent the slider from sliding downward. An air jet switch is provided on the top of the accommodating cavity. In the natural state, the inner cylinder presses the air jet switch upward under the action of the spring elastic force, and the air jet device is closed at this time. During the operation of the cyclone, Fine sand adheres to the inner wall of the inner cylinder. When the weight of the adhered fine sand reaches a threshold, the inner cylinder overcomes the elastic force of the spring under the action of itself and the gravity of the fine sand and slides downward. The jet switch rebounds and is triggered, and the jet device is started to spray air toward the inner wall of the inner cylinder to blow off the fine sand adhered to the inner wall of the inner cylinder. The downward force on the inner cylinder is weakened, so that the inner cylinder slides upward under the elastic force of the spring, and the jet switch is pressed upward to close. The sewage outlet can automatically start and close the jet device according to the amount of fine sand adhered to the inner wall of the inner cylinder, so as to achieve the effect of automatically unblocking the sewage outlet, and effectively solve the problem of easy blockage of the sewage outlet.

[0031] On the other hand, the slider is located at the top of the inner cylinder, and the outer sleeve is provided with a downward extending annular stopper on the inner side of the slider. The annular stopper blocks fine sand from entering the gap between the slider and the outer sleeve, effectively preventing the slider from getting stuck.

[0032] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0033] Example:

[0034] like Figures 1 to 3As shown, the present invention provides an anti-clogging cyclone, which includes: a sewage outlet 1 located at the bottom of the cyclone; the sewage outlet 1 includes: an inner cylinder 10, an outer shell 20, a spring 30, an air jet device 40 and an air jet switch 50; the outer shell 20 is integrally formed with the outer shell of the cyclone, the inner cylinder 10 slides freely up and down within the outer shell 20, the outer shell 20 is provided with the air jet device 40, the air jet port of the air jet device 40 faces the inner wall of the inner cylinder 10, the outer wall of the inner cylinder 10 is provided with an annular slider 11 extending outwardly, the inner wall of the outer shell 20 is provided with an accommodating cavity 21 for the slider 11 to slide up and down, the spring 30 is vertically arranged between the lower surface of the slider 11 and the bottom surface of the accommodating cavity 21 to prevent the slider 11 from sliding downward, the air jet switch 50 is fixed to the cavity ceiling of the accommodating cavity 21, and in a natural state, the inner cylinder 10 presses the air jet switch 50 upward under the action of the spring 30, and the air jet device 40 is turned off.

[0035] When the weight of the fine sand adhered to the inner wall of the inner cylinder 10 reaches a threshold value, the inner cylinder 10 overcomes the elastic force of the spring 30 under the action of itself and the gravity of the fine sand and slides downward, and the air jet switch 50 rebounds and is triggered, starting the air jet device 40 to spray air toward the inner wall of the inner cylinder 10, blowing off the fine sand adhered to the inner wall of the inner cylinder 10. The downward force on the inner cylinder 10 is weakened, so that the inner cylinder 10 slides upward under the elastic force of the spring 30, pressing upward to close the air jet switch 50; so that the sewage outlet 1 can automatically start and close the air jet device 40 according to the amount of fine sand adhered to the inner wall of the inner cylinder 10, thereby achieving the effect of automatically unblocking the sewage outlet 1, and effectively solving the problem that the sewage outlet 1 is easily blocked.

[0036] like Figure 2 、 Figure 3 As shown, the jet device 40 includes a jet chamber 41, which is located above the inner tube 10. The bottom of the jet chamber 41 gradually narrows to form a ring-shaped jet port. The gas in the jet chamber 41 is ejected through the gradually narrowing jet port. During the jetting process, the gas is pressurized and accelerated through the gradually narrowing jet port, thereby increasing the impulse of the ejected gas, which is conducive to blowing off the fine sand adhered to the inner wall of the inner tube 10.

[0037] like Figure 2 、 Figure 3 As shown, the jet device 40 further includes: an air supply pipe 42 and an electronic valve 43 ; the air supply pipe 42 supplies gas to the jet chamber 41 ; the electronic valve 43 is provided on the air supply pipe 42 to control the opening and closing of the air supply pipe 42 .

[0038] like Figure 2 、 Figure 3 As shown, the electronic valve 43 is electrically connected to the air jet switch 50. When the air jet switch 50 is pressed, the electronic valve 43 is closed, and when the air jet switch 50 rebounds naturally, the electronic valve 43 is opened.

[0039] like Figure 2 、 Figure 3 As shown, the lower surface of the slider 11 is provided with a first accommodating groove 12 extending upward, and the bottom surface of the accommodating cavity 21 is provided with a second accommodating groove 22 extending downward. The first accommodating groove 12 and the second accommodating groove 22 are arranged correspondingly, and the two ends of the spring 30 are respectively accommodated in the first accommodating groove 12 and the second accommodating groove 22, thereby enhancing the connection stability between the spring 30 and the slider 11 and the accommodating cavity 21, so that the spring 30 can only perform compression and extension movements vertically.

[0040] like Figure 2 、 Figure 3 As shown, the outer wall of the inner cylinder 10 is vertically provided with a plurality of guide blocks 13, and the inner wall of the outer shell 20 is provided with guide grooves 23 corresponding to the guide blocks 13. The guide blocks 13 slide freely up and down in the guide grooves 23, limiting the rotation of the inner cylinder 10 in the outer shell 20, so that the inner cylinder 10 can only slide up and down relative to the outer shell 20, thereby enhancing the connection stability between the inner cylinder 10 and the outer shell 20.

[0041] like Figure 2 、 Figure 3 As shown, the slider 11 is located at the top of the inner tube 10, and the outer sleeve 20 is provided with a downward extending annular stopper 24 on the inner side of the slider 11. The annular stopper 24 blocks fine sand from entering the gap between the slider 11 and the outer sleeve 20, effectively preventing the slider 11 from getting stuck.

[0042] like Figure 2 、 Figure 3 As shown, the air jet is opened on the lower surface of the stopper 24 so that the air jet is aligned with the inner wall of the inner cylinder 10 .

[0043] like Figure 1 As shown, the cyclone further includes: an inlet 2 and an overflow port 3. The inlet 2 is located on the side wall of the cyclone, and the overflow port 3 is located on the top of the cyclone.

[0044] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0045] 1. In the embodiment of the present invention, an outer sleeve integrally formed with the cyclone housing is provided at the sewage outlet, and an inner cylinder freely sliding up and down in the outer sleeve is provided. The outer sleeve is provided with an air jet device, and the air jet port of the air jet device faces the inner wall of the inner cylinder. A slider is provided on the outer wall of the inner cylinder extending outward. A receiving cavity is provided on the inner wall of the outer sleeve. A spring is provided between the lower surface of the slider and the bottom surface of the receiving cavity to prevent the slider from sliding downward. An air jet switch is provided on the top of the receiving cavity. In the natural state, the inner cylinder presses the air jet switch upward under the action of the spring elastic force, and the air jet device is turned off at this time. During the operation of the cyclone Fine sand adheres to the inner wall of the inner cylinder. When the weight of the adhered fine sand reaches a threshold, the inner cylinder overcomes the elastic force of the spring under the action of itself and the gravity of the fine sand and slides downward. The jet switch rebounds and is triggered, starting the jet device to spray air toward the inner wall of the inner cylinder, blowing off the fine sand adhered to the inner wall of the inner cylinder. The downward force on the inner cylinder is weakened, causing the inner cylinder to slide upward under the elastic force of the spring, pressing upward to close the jet switch; the sewage outlet can automatically start and close the jet device according to the amount of fine sand adhered to the inner wall of the inner cylinder, thereby achieving the effect of automatically unclogging the sewage outlet, and effectively solving the problem of easy blockage of the sewage outlet.

[0046] 2. In the embodiment of the present invention, the weight of the inner tube and the adhered fine sand is used as the condition for starting the jet device, and the dredging condition is very clear. Compared with the case in the background technology, it avoids the situation where a large amount of fine sand has accumulated at the sewage outlet, but the fine sand has not accumulated in the anti-blocking cavity to start the nozzle, resulting in blockage of the sewage outlet.

[0047] 3. In the embodiment of the present invention, through ingenious design, the bottom of the jet chamber is gradually narrowed to form an annular jet port, so that the gas is pressurized and accelerated through the jet port. The impulse of the ejected gas is sufficient to blow off the adhering fine sand. Therefore, only one air supply pipe is needed to supply air to the jet chamber to blow out an annular air column to blow off all the fine sand adhering to the inner wall of the inner cylinder.

[0048] 4. In the embodiment of the present invention, the slider is located at the top of the inner cylinder, and the outer sleeve is provided with a downwardly extending annular stopper on the inner side of the slider. The annular stopper blocks fine sand from entering the gap between the slider and the outer sleeve, effectively preventing the slider from getting stuck.
