Description

Technical Field

[0001] This invention relates to the field of liquid jigging equipment technology, and more particularly to special equipment for building material production, specifically a solid waste preparation equipment for roadbed raw materials, which is suitable for the promotion and service of resource recycling technology. Background Technology

[0002] With economic development and continuous urbanization, the amount of solid waste generated is increasing. Solid waste does not disappear naturally over time; it persists in the environment and causes pollution. By screening out concrete, bricks, and stones from solid waste and processing them through crushing and grading, it can be made into roadbed raw materials of different specifications for roadbed construction. Roadbed raw materials made from solid waste can replace traditional roadbed materials, reducing infrastructure construction costs and minimizing urban environmental pollution.

[0003] Roadbed materials made from solid waste contain impurities such as plastics, wood, foam, and soil. These impurities can seriously affect the mechanical properties, water stability, and durability of the roadbed. Current technologies often use air classifiers and jigs to separate impurities from the roadbed materials. However, the separation effect of air classifiers is easily affected by the shape, surface area, and humidity of the solid waste. For light materials that are damp, flaky, or adhering to solid waste, the separation effect is poor, resulting in a large number of impurities remaining in the solid waste, which cannot meet the requirements for the purity of the solid waste. Jigs generate a uniform pulsating water flow, and the degree of looseness of the solid waste at different positions on the screen plate is inconsistent, which can easily form a separation dead zone. This causes some solid waste to be discharged without being fully separated, affecting the overall separation effect. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a solid waste preparation roadbed raw material equipment, which reduces the dead zone of water flow, makes the solid waste in a loose and layered state, avoids the problem of material piling or incomplete sorting, and has a good effect on removing light impurities.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a solid waste preparation roadbed raw material equipment, comprising an annular housing, wherein an annular groove is provided on the top side of the annular housing, and not less than three coaxially sleeved inner dividing tubes are installed in the annular groove, wherein the inner dividing tubes divide the annular groove into dividing grooves that are one more than the number of inner dividing tubes.

[0006] A rotating annular screen is coaxially mounted on the top side of the annular housing. The annular screen completely covers the annular groove of the annular housing, and a drive mechanism that drives the annular screen to rotate is installed on the annular housing. An inner baffle tube is fixed on the top side of the annular screen at the position corresponding to the inner edge of the annular housing.

[0007] The inner wall and / or outer periphery of the inner dividing tube are equipped with a plurality of pulsation generating devices. Each pulsation generating device includes a rotating plate and a flexible tube. One end of the rotating plate is rotatably connected to the inner wall and / or outer periphery of the inner dividing tube. An elastic element is installed between the other end of the rotating plate and the inner dividing tube. Both ends of the flexible tube are respectively sealed to the inner dividing tube and the rotating plate. An opening is provided on the inner dividing tube to communicate with the inner cavity of the flexible tube.

[0008] The bottom side of the annular screen is fixed with a contact element corresponding to the position of each dividing groove.

[0009] The annular groove is filled with water. The driving mechanism drives the contact element to rotate through the annular screen. The contact element pushes the rotating plate of one of the pulsation generating devices to rotate. The water in the hose enters one of the dividing grooves through the opening and generates pulsating water flow. The pulsating water flow in two adjacent dividing grooves is generated at intervals.

[0010] As a preferred embodiment of the present invention, a conical guide with its tip pointing upward is fixed at the middle position of the annular screen, and a plurality of blocking components are fixed on the conical surface of the conical guide.

[0011] As a preferred embodiment of the present invention, a limit tube is fixed on the top side of the annular screen corresponding to the position of each inner dividing tube.

[0012] As a preferred embodiment of the present invention, it further includes an annular collecting shell, the inner wall of which is fixedly connected to the outer periphery of the annular housing shell, and a collecting groove is provided on the top side of the annular collecting shell. The outer edge of the top side of the annular housing shell is higher than the top side of the annular screen and the inner edge of the top side of the annular housing shell.

[0013] As a preferred embodiment of the present invention, a material passage hole is provided at the lowest point of the annular material collection trough, and the material passage hole is connected to the feed inlet of the screw conveyor.

[0014] As a preferred embodiment of the present invention, any one of the dividing slots is connected to at least three openings.

[0015] As a preferred embodiment of the present invention, the annular screen includes at least two fan-shaped support nets, and two adjacent fan-shaped support nets can be detachably connected.

[0016] As a preferred embodiment of the present invention, an elastic pad is fixed on the bottom side of the annular screen corresponding to the position of each inner dividing tube.

[0017] As a preferred embodiment of the present invention, the ratio of the volume of the inner cavity of the hose to the volume of the dividing groove is 1.0:5.0-30.0.

[0018] As a preferred embodiment of the present invention, the length of the dividing groove in the radial direction of the annular housing is 5.0cm-30.0cm, and the ratio of the inner diameter of the annular housing to the outer diameter of the annular housing is 1.0:1.0-5.0.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The solid waste preparation equipment for roadbed raw materials according to the present invention, on the one hand, the intermittent generation of pulsating water flow in two adjacent dividing tanks and the cooperation of the rotating annular screen cause the solid waste to be subjected to lateral shear force and stable alternating rising and falling force, which is conducive to the precise stratification of impurities, reduces the dead zone of water flow, and keeps the solid waste on the entire annular screen in an optimal loose and stratified state, avoiding the problems of material piling or incomplete sorting in existing jigs. The removal effect of light impurities is good, improving the mechanical properties, water stability and durability of the roadbed; on the other hand, the pulsation generating device Inside the water in the dividing tank, when the contact element and the rotating plate are not in contact, the water pressure inside and outside the hose is similar. The contact element consumes less energy during the process of squeezing the hose through the rotating plate, thus reducing the energy consumption of this solid waste preparation equipment for roadbed raw materials. On the other hand, when the solid waste on the top side of the annular screen passes the limiting pipe, the solid waste near the outer periphery of the limiting pipe leaves the outer periphery of the limiting pipe. The pulsating water flow generated by the pulsating device causes the solid waste near the inner wall of the limiting pipe to pass over the limiting pipe and fall to the position near the outer periphery of the limiting pipe. The solid waste passes through the limiting pipe to achieve the flipping of the upper and lower layers of solid waste, and the impurities in the solid waste are completely separated.

[0021] 2. In the solid waste preparation roadbed raw material equipment of the present invention, the layered and staggered blocking components on the conical guide ensure that water and solid waste are evenly distributed when falling on the annular screen, thus ensuring the reliability of the solid waste preparation roadbed raw material equipment.

[0022] 3. In the solid waste preparation roadbed raw material equipment of the present invention, the elastic pad increases the sealing between the bottom side of the annular screen and the top side of the inner dividing tube, and the inner dividing tube does not affect the rotation of the elastic pad with the annular screen.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Example 1:

[0031] Please see Figures 1-5 This embodiment discloses a solid waste preparation roadbed raw material equipment, including an annular housing 10. An annular groove is provided on the top side of the annular housing 10. No less than three coaxially sleeved inner dividing tubes 7 are fixedly installed in the annular groove. The inner dividing tubes 7 divide the annular groove into dividing grooves with one more number of inner dividing tubes 7 than the number of inner dividing tubes 7.

[0032] A coaxial annular screen 3 is mounted on the top side of the annular housing 10 via a bearing or rotating pin sleeve. The annular screen 3 completely covers the annular groove of the annular housing 10. A drive mechanism 8 is mounted on the annular housing 10 to drive the annular screen 3 to rotate via a drive frame. An inner baffle tube 5 is fixed on the top side of the annular screen 3 at the position corresponding to the inner edge of the top side of the annular housing 10. The top side of the inner dividing tube 7 and the bottom side of the annular screen 3 are slidably attached.

[0033] Each inner dividing tube 7 has several pulsation generating devices 9 installed on its inner wall and / or outer periphery. Each pulsation generating device 9 includes a rotating plate 91 and a watertight hose 92. One end of the rotating plate 91 is connected to the inner wall and / or outer periphery of the inner dividing tube 7 by a hinge or hinge seat. An elastic element 93 is installed between the other end of the rotating plate 91 and the inner dividing tube 7. Both ends of the hose 92 are sealed to the inner dividing tube 7 and the rotating plate 91, respectively. An opening 14 is provided on the inner dividing tube 7 to connect to the inner cavity of the hose 92. The elastic element 93 causes the rotating plate 91 to drive the hose 92 to unfold, allowing the hose 92 to draw in water.

[0034] Contact elements 11 are fixed on the bottom side of the annular screen 3 corresponding to the position of each dividing groove.

[0035] The annular groove is filled with water. The drive mechanism 8 drives the contact member 11 to rotate around the axis of the annular housing 10 through the annular screen 3. The contact member 11 pushes the rotating plate 91 of one of the pulsation generating devices 9 to rotate. The water in the hose 92 enters one of the dividing grooves through the opening 14 and generates pulsating water flow. Pulsating water flow is generated in two adjacent dividing grooves at intervals.

[0036] Furthermore, the ratio of the volume of the inner cavity of the hose 92 to the volume of the dividing groove is 1.0:5.0-30.0.

[0037] Furthermore, the length of the dividing groove in the radial direction of the annular housing 10 is 5.0cm-30.0cm, and the ratio of the inner diameter of the annular housing 10 to the outer diameter of the annular housing 10 is 1.0:1.0-5.0.

[0038] Furthermore, any one of the dividing slots is connected to at least three openings 14.

[0039] Furthermore, the rotating plate 91 is an arc-shaped plate, thereby increasing the volume of water discharged by the hose 92 in a single operation.

[0040] Furthermore, the hose 92 is made of soft rubber, soft plastic or soft silicone, the elastic element 93 is a spring or elastic rod, and the contact element 11 is a contact rod, contact plate or rotating wheel.

[0041] Furthermore, the drive mechanism 8 is an electric motor, a pneumatic motor, or a hydraulic motor. The drive mechanism 8 used in this invention is a commonly used device in the prior art, and its working method and structure are well-known technologies, which will not be described in detail here.

[0042] The working process and principle of this embodiment are as follows:

[0043] The operator activates the drive mechanism 8, and the external water pump continuously delivers water to the top side of the annular screen 3 near the inner edge. The dividing trough is filled with water, and the external conveying equipment continuously transports solid waste to the top side of the annular screen 3 near the inner edge.

[0044] The drive mechanism 8 drives the contact member 11 to rotate continuously around the axis of the annular housing 10 via the annular screen 3. One of the contact members 11 pushes the rotating plate 91 of the pulsation generating device 9 it contacts to rotate. The rotating plate 91 squeezes the hose 92, causing the water in the hose 92 to enter one of the dividing grooves through the opening 14 and generate pulsating water flow. The elastic potential energy of the elastic member 93 increases. After the contact member 11 and the rotating plate 91 are separated, the elastic member 93 pushes the rotating plate 91 to rotate, causing water to be drawn into the hose 92.

[0045] The rotating annular screen 3 causes water and solid waste to move towards the outer edge of the annular screen 3. Pulsating water flow is generated intermittently in the two adjacent dividing grooves. The pulsating water flow passes upward through the annular screen 3 and acts on the solid waste on the annular screen 3, making the solid waste on the annular screen 3 loose. The intermittent generation of pulsating water flow in the two adjacent dividing grooves and the rotation of the annular screen 3 make the solid waste subject to lateral shear force and stable alternating upward and downward force, which is conducive to the precise stratification of impurities, reduces the dead zone of water flow, and keeps the solid waste on the entire annular screen 3 in an optimal loose and stratified state. This avoids the problems of material piling or incomplete sorting in existing jigs. The removal effect of light impurities is good, improving the mechanical properties, water stability and durability of the roadbed.

[0046] Water has a lower density than solid waste. Water from the top edge of the annular screen 3 leaves the screen and carries impurities into the first collection container outside. Solid waste from the top edge of the annular screen 3 leaves the screen and carries solid waste into the second collection container outside. The distance that the water carries the impurities is greater than the distance that the solid waste flies, thus achieving the separation of impurities and solid waste.

[0047] The pulsation generator 9 is located inside the water in the dividing tank. When the contact element 11 and the rotating plate 91 are not in contact, the water pressure inside and outside the hose 92 is similar. The contact element 11 consumes less energy during the process of squeezing the hose 92 through the rotating plate 91, thus reducing the energy consumption of this solid waste preparation roadbed raw material equipment.

[0048] Furthermore, the staff can adjust the height of the elastic element 93 or the vertical length of the contact element 11 to ensure that the elastic element 93 does not affect the movement of the contact element 11.

[0049] Furthermore, the staff adjusts the distance between the contact 11 and the inner dividing tube 7, and adjusts the position of the pulsation generating device 9 on the inner dividing tube 7, so as to achieve the generation of pulsating water flow intervals in two adjacent dividing slots, and the pulsating water flow in two adjacent dividing slots of one dividing slot is generated simultaneously.

[0050] Furthermore, the inner baffle 5 prevents water and solid waste on the annular screen 3 from falling off the inner edge of the annular screen 3.

[0051] Furthermore, the intensity of the pulsating water flow can be adjusted by changing the size of the opening 14 and / or changing the rotation angle and / or changing the length of the rotating plate 91.

[0052] Furthermore, the linear velocity of the inner edge of the annular screen 3 is 0.2 m / s-3.0 m / s, and the linear velocity of the outer edge of the annular screen 3 is 0.5 m / s-5.0 m / s.

[0053] Furthermore, the particle size of the solid waste is 1.0mm-20.0mm.

[0054] Example 2:

[0055] like Figure 1 and Figure 2 As shown, this embodiment discloses a solid waste preparation roadbed raw material equipment, whose structure is roughly the same as that of Embodiment 1. The difference is that in this embodiment, a conical guide 1 with the tip pointing upward is fixed in the middle position of the annular screen 3, and several layered and staggered blocking components 2 are fixed on the conical surface of the conical guide 1.

[0056] The working process and principle of this embodiment are as follows:

[0057] The operator activates the drive mechanism 8, and an external water pump continuously supplies water to the tip of the conical guide 1. The dividing trough is filled with water, and the external conveying equipment continuously transports solid waste to the tip of the conical guide 1. The layered and staggered blocking parts 2 on the conical guide 1 ensure that the water and solid waste are evenly distributed when they fall onto the annular screen 3, thus guaranteeing the reliability of the equipment for preparing roadbed raw materials from solid waste.

[0058] Furthermore, the blocking component 2 is a blocking plate or a blocking rod.

[0059] Example 3:

[0060] like Figure 1 and Figure 2 As shown, this embodiment discloses a solid waste preparation roadbed raw material equipment, whose structure is roughly the same as that of Embodiment 1 or Embodiment 2. The difference is that in this embodiment, a limit tube 6 is fixed on the top side of the annular screen 3 corresponding to the position of each inner dividing tube 7.

[0061] The working process and principle of this embodiment are as follows:

[0062] The drive mechanism 8 drives the annular screen 3 to rotate. The solid waste on the annular screen 3 moves to the outer edge of the annular screen 3. When the solid waste on the top side of the annular screen 3 passes the limiting pipe 6, the solid waste near the outer periphery of the limiting pipe 6 leaves the outer periphery of the limiting pipe 6. The pulsating water flow generated by the pulsating generator 9 causes the solid waste near the inner wall of the limiting pipe 6 to pass over the limiting pipe 6 and fall to the position near the outer periphery of the limiting pipe 6. The solid waste passes through the limiting pipe 6 to achieve the upper and lower layers of solid waste flipping, and the impurities in the solid waste are completely separated.

[0063] Furthermore, the annular housing 10 and the inner dividing tube 7 are integrally formed.

[0064] Example 4:

[0065] like Figure 1 , Figure 2 and Figure 4As shown, this embodiment discloses a solid waste preparation roadbed raw material equipment, whose structure is roughly the same as that of Embodiment 1. The difference is that this embodiment also includes an annular aggregate shell 4. The inner wall of the annular aggregate shell 4 is fixedly connected to the outer periphery of the annular housing shell 10. An aggregate trough is opened on the top side of the annular aggregate shell 4. The outer edge of the top side of the annular housing shell 10 is higher than the top side of the annular screen 3 and the inner edge of the top side of the annular housing shell 10.

[0066] The working process and principle of this embodiment are as follows:

[0067] Solid waste falls into the collection trough after detaching from the top side of the annular screen 3. Water flows out over the outer edge of the top side of the annular housing 10 after detaching from the annular screen 3. The water flowing out from the outer edge of the top side of the annular housing 10 carries away impurities.

[0068] Example 5:

[0069] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment discloses a solid waste preparation roadbed raw material equipment, whose structure is roughly the same as that of Embodiment 1. The difference is that the bottom of the annular collection shell 4 collection trough in this embodiment is inclined, and a material passage hole is opened at the lowest point of the collection trough. The material passage hole is connected to the feed port of the screw conveyor 13.

[0070] The working process and principle of this embodiment are as follows:

[0071] The screw conveyor 13 transports the solid waste from the bottom of the collection trough out of the collection trough, reducing the amount of solid waste accumulation in the collection trough and reducing the maintenance workload of the equipment for preparing roadbed raw materials from solid waste.

[0072] Example 6:

[0073] like Figure 1 and Figure 2 As shown, this embodiment discloses a solid waste preparation roadbed raw material equipment, whose structure is roughly the same as that of Embodiment 1. The difference is that the annular screen 3 in this embodiment includes no less than two fan-shaped support nets, and two adjacent fan-shaped support nets can be detachably connected. The fan-shaped support nets are easy to replace and repair after damage.

[0074] Example 7:

[0075] like Figure 3 As shown, this embodiment discloses a solid waste preparation roadbed raw material equipment, whose structure is roughly the same as that of Embodiment 1. The difference is that in this embodiment, an annular elastic pad 12 is fixed on the bottom side of the annular screen 3 corresponding to the position of each inner dividing tube 7, and the inner dividing tube 7 and the elastic pad 12 slide and fit together.

[0076] The working process and principle of this embodiment are as follows:

[0077] The elastic pad 12 increases the sealing between the bottom side of the annular screen 3 and the top side of the inner dividing tube 7, and the inner dividing tube 7 does not affect the elastic pad 12 from rotating with the annular screen 3.

[0078] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
