Description

Technical Field

[0001] The present invention relates to a sorting device for solid waste, and particularly to an efficient flow-blocking sedimentation separator. Background Art

[0002] In modern life, with the increasing advancement of urbanization, a large amount of waste materials are generated, especially solid waste. Simple stacking and treatment of solid waste will occupy a large amount of land. Therefore, the classification and sorting of solid waste are becoming increasingly important. In the treatment of solid waste, it involves the process of sorting large solid waste materials. In the existing process, a Z-type vertical air separator is first used to screen large materials, and tiny materials are discharged with the wind. Its defects are as follows: First, the tiny materials enter the atmosphere, increasing the dust content in the air, especially some metal dust or toxic dust, seriously polluting the air and damaging human health; Second, a large amount of useful recyclable materials are contained in the tiny materials, and direct discharge without recycling is a serious waste of resources. Summary of the Invention

[0003] To solve one or more of the above problems, the present invention provides an efficient flow-blocking sedimentation separator.

[0004] According to one aspect of the present invention, the efficient flow-blocking sedimentation separator includes a casing, an upper guiding cover, a connecting member, and a flow distribution pipe network.

[0005] The casing includes a tubular main separation chamber. The upper end of the main separation chamber is detachably connected to a conical tubular upper casing, and the lower end is integrally connected to a conical tubular lower casing. The inner cavities of the main separation chamber, the upper casing, and the lower casing are directly connected to each other. The upper end of the upper casing is open to form an air outlet, and the lower end of the lower casing is open to form a dust outlet. The air outlet is connected to a fan, and an air inlet pipe is provided on the outer wall of the lower end of the casing.

[0006] The upper guiding cover includes a cylindrical cover body. The lower surface of the cover body is a spherical curved flow-blocking surface, and the lower vertex of the flow-blocking surface is located on the center line of the main separation chamber.

[0007] The connecting column of the connecting member is located at the upper center of the inner cavity of the main separation chamber. The lower end of the connecting column is connected to the center of the upper surface of the cover body. The outer wall of the upper end of the connecting column is connected to the inner ends of several circumferentially arranged outer wing plates, and the outer ends of each connecting column are perpendicularly connected to the upper four walls of the main separation chamber.

[0008] The flow distribution pipe network is an elastic rubber circular pipe. The upper port of the flow distribution pipe network is fixed to the outer wall of the cover body by a tight fit of an elastic deformation force on the shaft sleeve. A plurality of diversion holes are evenly arranged in a circumferential array on the tube wall at the lower end of the flow distribution pipe network.

[0009] The dusty air flow enters the main separation chamber from the air inlet pipe, becomes a vertical upward flow, turns into a horizontal flow after passing through the upper flow-blocking surface, and flows through the diversion holes to the four walls of the main separation chamber. Then it flows upward under the low pressure of the upper shell until it flows out of the air outlet. The dust is blocked and settles downward on the flow-blocking surface, the pipe wall of the diversion pipe network, and the four walls of the main separation chamber, and enters the lower shell until the dust discharge port.

[0010] This high-efficiency flow-blocking and settling separator is provided with a main separation chamber. The light materials and dust enter the main separation chamber from the air inlet pipe. Since the outlet area of the air inlet pipe is much smaller than that of the main separation chamber, the materials will suddenly expand, lose weight, stall and settle. The low-speed mixed air flow is blocked by the spherical curved flow-blocking surface upward, and the mixed air flow will diverge in all directions and simultaneously encounter the diversion pipe network made of elastic rubber round tubes, so that a large amount of light materials and dust settle to the dust discharge port. The beneficial effects are as follows: First, this settling separator realizes the settling separation of a large amount of light materials and dust, avoids dust pollution of the air, effectively recovers valuable dust, protects the environment, and rationally utilizes resources; Second, this settling separator has triple flow-blocking and speed reduction. First, the speed is reduced in the main separation chamber. Second, the flow-blocking surface blocks and converts the vertical flow into a horizontal flow. Finally, the diversion pipe network blocks and screens, and the flow-blocking and settling effect is good; Third, the diversion pipe network uses rubber round tubes, which can be simply and firmly connected to the cover body, can be quickly replaced, can effectively reduce the impact of the low-speed mixed air flow, has a long service life, and at the same time, the appropriate elastic deformation can make the adhered dust break away and fall, avoiding blockage; Fourth, the spherical flow-blocking surface can make the air flow uniform in all directions, avoid the phenomenon of local air flow concentration, can use the diversion pipe network in all directions, and protect the diversion pipe network; Fifth, the connecting piece adopts circumferentially arrayed outer wing plates and a vertical connecting column in the center, and evenly distributes the load of the connecting column to each surface of the main separation chamber.

[0011] In some embodiments, the outer wall of the cover body extends vertically upward to form an upper ring, and several outer convex ribs are circumferentially arrayed at the lower end of the outer wall of the cover body. The diversion pipe network is provided with several circumferentially arrayed lower slits, and the lower slits extend vertically upward from the lower surface of the diversion pipe network to the middle of the circumferential wall. The circumferential array of the lower slits is the same as that of the outer convex ribs and has the same width, and the outer convex ribs are tightly nested in the upper ends of the lower slits; the upper end opening of the diversion pipe network is tightly sleeved with the upper ring.

[0012] In some embodiments, the lower end of the connecting column is provided with an externally threaded end, and a central threaded blind hole is provided at the center of the upper surface of the cover body. The externally threaded end is screwed into the central threaded blind hole, so that the connecting column and the upper guiding cover are detachably connected into one body; a lock nut is also sleeved on the externally threaded end, and the lock nut fits against the upper surface of the cover body;

[0013] Or the connecting column is an internally threaded pipe, and a threaded column is provided at the center of the upper surface of the cover body. The threaded column is screwed into the internally threaded pipe, so that the connecting column and the upper guiding cover are detachably connected into one body.

The outer wall of the upper end of the connecting column and the inner ends of the four circumferentially arrayed outer wing plates are welded together, and the outer end of each connecting column is perpendicularly welded to the upper four walls of the corresponding main separation chamber.

[0015] In some embodiments, the outer wall of the shunt pipe network is connected to the inner wall of the main separation chamber through an annular auxiliary separation net. A number of ventilation holes are evenly distributed on the auxiliary separation net, and the auxiliary separation net is a wire mesh or a rubber plate.

[0016] In some embodiments, a maintenance through hole is provided on one side wall of the main separation chamber.

[0017] The main body of the maintenance door has the same contour and dimensions as the maintenance through hole. The outer edge of the main body extends outward to form a sealing cover. One side of the sealing cover is connected to the outer wall of the main separation chamber through a hinge. The main body and the maintenance through hole are nested, and the sealing cover fits against the outer wall of the main separation chamber.

[0018] In some embodiments, the main body is made of transparent acrylic material; a handle is also provided on the outer side surface of the main body.
