Description

Technical Field

[0001] The invention relates to the technical field of cyclones, and in particular to a novel cyclone for building drainage. Background Art

[0002] The hydrocyclone is a common separation and classification equipment. Its working principle is centrifugal sedimentation. The basic principle is to separate liquid-liquid, liquid-solid, liquid-gas and other two-phase mixtures with a certain density difference under the action of centrifugal force. When the two-phase mixed liquid to be separated enters the hydrocyclone tangentially from the periphery of the hydrocyclone at a certain pressure, different centrifugal forces will be generated to separate the two phases.

[0003] At present, cyclones are widely used in the process of building drainage, and most of the cyclones on the market are composed of structures such as water inlet pipe, cyclone body, cone, sand settling component and filter component. Combining the working principle of the cyclone, it can be seen that it is separated according to density difference. For drainage in construction, there are more sand and gravel in the water. Conventional cyclones can basically meet the separation of sand and gravel and water, but there are often some other impurities in the deceleration drainage, such as leaves, ropes and other impurities. These impurities are not only difficult to be separated by the cyclone, but also easily cause the water inlet pipe to be blocked, thus affecting the normal use of the cyclone.

[0004] At the same time, the sand settling components of conventional cyclones often need to be shut down before the sand and gravel deposited inside can be cleaned, which cannot achieve the purpose of cleaning the sand during the separation process. This also means that after the cyclone has worked for a certain period of time, it is necessary to shut down the cyclone to clean its sand settling components, which in turn causes the drainage process to be interrupted. Summary of the invention

[0005] In order to solve the above problem, that is, the problem that impurities such as leaves and ropes in building drainage easily cause blockage to the water inlet pipe of the cyclone, the present invention proposes a new type of cyclone for building drainage, which includes a cyclone body, a sand settling component is arranged at the bottom end of the cyclone body, an overflow pipe is arranged at the top end of the cyclone body, the cyclone body is also connected with a water inlet pipe, a filter assembly is installed on the water inlet pipe, the filter assembly includes a detachable upper filter shell and a lower filter shell, the lower filter shell is connected with the water inlet pipe, a conical filter screen is arranged in the lower filter shell, a collecting box is arranged at the center of the filter screen, the collecting box is arranged at the bottom end of the filter screen, and is coaxially arranged with the filter screen, and a hydrophobic hole is opened at the bottom end of the collecting box.

[0006] The present invention is further configured as follows: the bottom end of the filter screen is configured to have the same diameter as the opening of the collection box, and the opening of the collection box is configured to have the same height as the bottom end of the filter screen.

[0007] The present invention is further configured as follows: a bracket is connected to the bottom end of the filter screen, and the collection box is supported on the bracket.

[0008] The present invention is further configured as follows: a diverter plate is provided above the collection box, the diameter of the diverter plate is not less than the opening diameter of the collection box, and the diverter plate is coaxially arranged with the collection box.

[0009] The present invention is further configured as follows: the edge of the diverter plate is provided with an outward flange facing downward.

[0010] The present invention is further configured as follows: the sand settling assembly includes a sand settling box, an opener and an opening piece, the sand settling box is connected to the bottom end of the cyclone body, the opener is arranged inside the sand settling box and is communicated with the cyclone body, the opener includes four elastic triangular metal plates, the four metal plates are arranged in a rectangular shape, and the four metal plates are together arranged to form a quadrangular pyramid, the opening piece includes a ring adapted to the opener, the ring is sleeved on the opener, the ring is connected to an adjusting piece through a connecting rod, the adjusting piece is arranged on the outside of the sand settling box, and the adjusting piece is threadedly connected to the cyclone body, and the end of the connecting rod facing away from the ring is rotatably connected to the adjusting piece.

[0011] The present invention is further configured as follows: two sealing sockets are provided at the top of the sand settling box, and the connecting rod is passed through the sealing sockets.

[0012] The present invention is further configured as follows: a baffle is inserted at the bottom end of the sand settling box.

[0013] The beneficial effects of the present invention are:

[0014] 1. Through the cooperation of the filter and the collection box, the water can flow downward along the filter. In the process of flowing through the filter, the water will leak through the filter and then flow into the water inlet pipe, while the larger impurities will be filtered out by the filter. Moreover, since the filter is set to be conical, the impurities remaining on the filter can be flushed into the collection box under the continuous impact of the water flow, and the filtered impurities are collected centrally to prevent the impurities from flowing into the cyclone body with the water flow. At the same time, since the water flow can continuously flush the impurities on the filter, the filtered impurities will not accumulate on the filter, that is, it will not cause clogging.

[0015] 2. Through the cooperation of the adjusting member, the sleeve ring and the opener, the purpose of controlling the opening and closing of the opener can be achieved. During use, the opener is in a normally open state, so that the separated mud and sand can fall into the sand settling box. When the mud and sand in the sand settling box needs to be cleaned, the sleeve ring can be driven upward by the adjusting member to squeeze the four metal plates to gather toward the center and fit each other. At this time, the connecting pipe between the cyclone body and the sand settling box can be closed, and the sand settling box can be cleaned by pulling out the baffle.

DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0030] The present invention proposes a new type of cyclone for building drainage, comprising a cyclone body 1, a sand settling assembly 2 is installed at the bottom end of the cyclone body 1 for centralized collection of separated silt, an overflow pipe 11 is connected to the top end of the cyclone body 1 for allowing low-density materials to flow out of the overflow pipe 11, and a water inlet pipe 12 is also connected to the side wall of the cyclone, and the water inlet pipe 12 is used to fill the cyclone body 1 with building drainage.

[0031] A filter assembly 3 is installed on the water inlet pipe 12 , and the filter assembly 3 includes a detachable upper filter shell 31 and a lower filter shell 32 . The bottom end of the upper filter shell 31 is connected to the top end of the upper filter shell 31 by bolts, and the bottom end of the lower filter shell 32 is connected to the water inlet pipe 12 .

[0032] A conical filter screen 321 is arranged in the lower filter shell 32, and one end of the filter screen 321 with a large diameter is welded to the edge of the top of the lower filter shell 32, and one end of the filter screen 321 with a small diameter is arranged in the lower filter shell 32, and a bracket is welded to the end of the filter screen 321 with a small diameter, and the bracket is composed of two U-shaped frames, and the two U-shaped frames are arranged in a cross shape. A collecting box 33 is supported in the bracket, and the collecting box 33 is arranged at the center of the filter screen 321, and the collecting box 33 is coaxially arranged with the filter screen 321, and a hydrophobic hole is opened at the bottom of the collecting box 33.

[0033] The bottom end of the filter 321 is set to have the same diameter as the opening of the collection box 33 , that is, the end with a smaller diameter of the filter 321 is set to have the same diameter as the opening of the collection box 33 , and the opening of the collection box 33 is set at the same height as the bottom end of the filter 321 .

[0034] When water flows through the filter 321 , larger impurities, such as leaves or ropes, will be filtered out, and the impurities attached to the filter 321 will be rushed to the collection box 33 under the impact of the water flow and collected in the collection box 33 .

[0035] A diverter plate 331 is also provided above the collection box 33, and the diverter plate 331 is connected to the collection box 33 through a vertical rod, wherein one end of the vertical rod is welded to the opening of the collection box 33, and the other end of the vertical rod is welded to the diverter plate 331. The diameter of the diverter plate 331 is not less than the opening of the collection box 33, and the diverter plate 331 is coaxially arranged with the collection box 33. An outer flange 3311 is integrally provided on the edge of the diverter plate 331, and the outer flange 3311 is arranged to be tilted downward, that is, the outer flange 3311 is arranged perpendicular to the filter screen 321.

[0036] When the water flows into the filter assembly 3, the water that impacts the diverter plate 331 will be diverted toward the filter screen 321 by the outer flange 3311, that is, the water will not directly impact the collection box 33. The filter screen 321 can filter out impurities in the water, that is, larger impurities such as leaves or ropes, and the water can continue to flow to the water inlet pipe 12 along the filter holes of the filter screen 321. Under the continuous flushing of the water flow, the filtered impurities can be flushed into the collection box 33 for centralized collection, and because the water flow will not directly impact the collection box 33, the impurities in the collection box 33 will not splash around due to the impact of the water flow. In this way, not only can the larger impurities in the building drainage be filtered out to avoid affecting the operation of the cyclone body 1, but also impurities can be prevented from remaining on the filter screen 321 and clogging the filter screen 321.

[0037] The sand settling assembly 2 includes a sand settling box 21, an opener 22 and an opening piece 23. The sand settling box 21 is welded to the bottom end of the cyclone body 1, the opener 22 is arranged inside the sand settling box 21, and the opener 22 is welded to the top of the sand settling box 21. The opener 22 is connected to the cyclone body 1, thereby making the sand settling box 21 connected to the cyclone body 1.

[0038] The opener 22 includes four elastic triangular metal plates, which are arranged in an isosceles triangle. The four metal plates are arranged in a square, and the four metal plates are arranged together to form a quadrangular pyramid. The opening piece 23 includes a collar 231 adapted to the opener 22, and the collar 231 is coaxially sleeved on the opener 22. Two connecting rods 232 are welded on the kit, and the two connecting rods 232 are symmetrically arranged about the axis of the collar 231. The connecting rods 232 are arranged through the sand settling box 21, and one end of the two connecting rods 232 away from the collar 231 is commonly connected to a swivel. The bottom end of the cyclone body 1 is also threadedly connected to an adjusting member 233, and the swivel is rotatably connected to the adjusting member 233. When the adjusting member 233 is rotated, the collar 231 can be driven to move up and down.

[0039] The top of the sand settling box 21 is also provided with two sealing sockets 211 , and two connecting rods 232 are passed through the sealing sockets 211 .

[0040] The sand settling box 21 is provided with a socket, and a slot corresponding to the socket is provided on the inner surface of the sand settling box 21 on the side away from the socket, and a baffle 212 is inserted in the socket, and one side of the baffle 212 inserted in the sand settling box 21 is inserted into the slot. It should be noted that a rubber sealing edge needs to be provided on the edge of the plug board, and the socket and the slot need to be sealed to ensure their sealing.

[0041] It should be noted that the opening is in a normally open state when performing cyclone separation. Fig. 9In the state shown, the separated silt can directly fall into the sand settling box 21.

[0042] When the sand box 21 is full, the adjusting member 233 is rotated to move upward, thereby driving the collar 231 to move upward as well. The collar 231 will squeeze the four metal plates simultaneously during the movement, so that the four metal plates gather toward the axis at the same time, until the four metal plates contact each other to form a quadrangular pyramid. At this time, the opener 22 is closed, the cyclone body 1 is not connected to the sand box 21, and the baffle 212 is pulled out to achieve the purpose of cleaning the sand box 21.

[0043] It should be noted that the edges of the four metal plates can be sealed to ensure better sealing when closed. However, due to the cyclone drainage, the sealing requirements do not need to be too high. Even when cleaning the sand settling box 21, there is less water dripping or flowing out of the opener 22, which will not have much impact on the cyclone process. Therefore, the cleaning effect of the sand settling box 21 can be met without sealing.

[0044] In summary, the present invention can make the water flow downward along the filter screen 321 through the cooperation between the filter screen 321 and the collecting box 33. In the process of flowing through the filter screen 321, the water flow will leak through the filter screen 321 and then flow into the water inlet pipe 12, and the larger impurities will be filtered out by the filter screen 321. Moreover, since the filter screen 321 is configured to be conical, the impurities remaining on the filter screen 321 can be flushed into the collecting box 33 under the continuous impact of the water flow, and the filtered impurities are collected centrally to prevent the impurities from flowing into the cyclone body 1 with the water flow. At the same time, since the water flow can continuously flush away the impurities on the filter screen 321, the filtered impurities will not accumulate on the filter screen 321, that is, no clogging problem will be caused. Through the cooperation of the adjusting member 233, the collar 231 and the opener 22, the purpose of controlling the opening and closing of the opener 22 can be achieved. During use, the opener 22 is in a normally open state, so that the separated mud and sand can fall into the sand settling box 21. When the mud and sand in the sand settling box 21 need to be cleaned, the collar 231 can be driven upward by the adjusting member 233, thereby squeezing the four metal plates to gather toward the center and fit each other. At this time, the connecting pipe between the cyclone body 1 and the sand settling box 21 can be closed, and the sand settling box 21 can be cleaned by pulling out the baffle 212.
