Technical Field

[0001] The present invention relates to the technical field of waste treatment, and specifically to a vibration screening air separation device and an air separation method. Background Art

[0002] Currently, the treatment of waste mainly adopts methods such as manual sorting, mechanical air separation, or a combination of the above two; the reason is that there are various types of waste, including domestic waste, construction waste, and decoration waste, etc. With the continuous acceleration of the urbanization process, the generation of the above-mentioned waste in cities has reached record highs; based on the above background, China has increased the intensity of the discharge and rectification of the above-mentioned waste to focus on environmental protection and resource recycling.

[0003] Existing mechanical air separation equipment has many defects: 1. There are various types of waste, and different air separation equipment is required to separate different types of waste during the air separation process, resulting in defects such as large equipment investment and large equipment floor area; 2. There are various types of waste, resulting in poor waste classification effect during the air separation process, and manual sorting is required in the early and later stages to improve the sorting accuracy; 3. The waste treatment capacity of existing air separation equipment is small, and it takes a long time and has low air separation efficiency when a large amount of waste needs to be air separated; 4. Some enterprises have increased the air volume of the fan to improve the waste treatment efficiency of the air separation equipment. Although this method slightly improves the waste treatment efficiency, the waste classification effect is worse than before. Some heavy substances will enter the light material outlet under the action of strong air volume, and some light material waste keeps floating in the air separation box; in severe cases, it affects the normal operation of the air separation equipment.

[0027] An air separation method for a vibrating screening air separation device, the air separation method includes a screening method for a large amount of materials, a screening method for a small amount of materials with many material types, and a screening method for a small amount of materials;

[0028] a. The screening method for a large amount of materials includes the following steps:

[0029] Step 1: When the amount of materials is greater than 150 t / h, the materials enter the relaxation screen part through the material inlet and pass through the relaxation screen body. The relaxation screen vibration motor with an exciter starts, driving the materials to disperse and move forward evenly in the relaxation screen body to the distributor part. The distributor vibration motor with an exciter starts to further disperse the materials in the distributor until the thickness of the materials is uniform, and at the same time, they are discharged evenly from the distributor part;

[0030] When the amount of materials is large and there are many material types, smaller materials can be screened by the relaxation screen body. The materials passing through the screen are discharged through the outlet of the materials passing through the relaxation screen; the materials remaining on the screen are discharged through the discharge port of the relaxation screen part, the inlet port of the distributor part, and the discharge port of the distributor part;

[0031] The above process realizes the primary selection of the materials and makes the materials have a uniform thickness and move forward at a uniform speed, creating conditions for the air separation of the materials;

[0032] Step 2: The material is discharged from the discharge port of the distributor section. Meanwhile, the centrifugal fan is started. The sorting air enters the air box through the air outlet pipe. Under the action of several staggered baffle plates, the sorting air is evenly distributed. The evenly distributed sorting air enters the air outlet of the uniform air outlet device through the flexible connection pipe and acts on the material to achieve air separation of the material. The air after air separation is discharged through the return air pipe with an induced draft fan;

[0033] In the above process, it is ensured that the air volume discharged from the air outlet is uniform, providing guarantee for the accurate screening of the material;

[0034] Step 3: When the sorting air acts on the material, the heavy substances in the material have a small parabola due to their large specific gravity, and the heavy substances fall into the heavy material outlet inside the fixed flap; the light substances in the material have a large parabola due to their small specific gravity, and the light substances fall into the light material outlet outside the fixed flap, completing the screening;

[0035] b. The screening method for a small amount of material and a variety of material types includes the following steps:

[0036] Step 1: When the material volume is no more than 150 t / h and there are many material types, the material enters the relaxation screen section through the material inlet and passes through the relaxation screen body. The relaxation screen vibration motor with an exciter is started. The relaxation screen body screens the smaller materials. The undersize materials are discharged through the undersize material outlet of the relaxation screen. The oversize materials move forward evenly and at a constant speed at the upper part of the relaxation screen body. The oversize materials are discharged through the discharge port of the relaxation screen section, the feed port of the distributor section, and the discharge port of the distributor section;

[0037] The above process realizes the preliminary selection of the material and makes the material move forward evenly and at a constant speed, creating conditions for the air separation of the material;

[0038] Step 2: The material is discharged from the discharge port of the distributor section. Meanwhile, the centrifugal fan is started. The sorting air enters the air box through the air outlet pipe. Under the action of several staggered baffle plates, the sorting air is evenly distributed. The evenly distributed sorting air enters the air outlet of the uniform air outlet device through the flexible connection pipe and acts on the material to achieve air separation of the material. The air after air separation is discharged through the return air pipe with an induced draft fan;

[0039] In the above process, it is ensured that the air volume discharged from the air outlet is uniform, providing guarantee for the accurate screening of the material;

[0040] Step 3: When the sorting air acts on the material, the heavy substances in the material have a small parabola due to their large specific gravity, and the heavy substances fall into the heavy material outlet inside the fixed flap; the light substances in the material have a large parabola due to their small specific gravity, and the light substances fall into the light material outlet outside the fixed flap, completing the screening;

[0041] c. The screening method for a small amount of material includes the following steps:

[0042] Step 1: When the material quantity is no more than 150 t / h, the material enters the distributor in the distributor section through the material inlet. The vibration motor of the distributor with an exciter starts, making the material thickness uniform in the distributor. Meanwhile, the material is discharged evenly from the outlet of the distributor section at a uniform speed;

[0043] The above process makes the material advance with uniform thickness and speed, creating conditions for the air separation of the material;

[0044] Step 2: The material is discharged from the outlet of the distributor section. Meanwhile, the centrifugal fan is started. The sorting air enters the air box through the air outlet pipe. Under the action of several staggered baffle plates, the sorting air is evenly distributed. The evenly distributed sorting air enters the air outlet in the uniform air outlet device through the flexible connection pipe and acts on the material to achieve the air separation of the material. The air after air separation is discharged through the return air pipe with an induced draft fan;

[0045] In the above process, it is ensured that the air volume from the air outlet is uniform, providing guarantee for the accurate screening of the material;

[0046] Step 3: When the sorting air acts on the material, the heavy substances in the material have a large specific gravity and a small parabola, and the heavy substances fall into the heavy material outlet inside the fixed flap; the light substances in the material have a small specific gravity and a large parabola, and the light substances fall into the light material outlet outside the fixed flap, completing the screening;

[0047] Due to the different types and densities of the materials, it is necessary to adjust the height and angle of the uniform air outlet device, adjust the height and angle of the fixed flap left and right, and adjust the uniform air outlet device and the fixed flap simultaneously;

[0048] When it is necessary to adjust the height of the uniform air outlet device, manually make the screw rod go up by adjusting the nut. The screw rod pushes the uniform air rotating shaft, making the uniform air rotating shaft generate an upward displacement, and then the uniform air outlet device can move upward; manually make the screw rod go down by adjusting the nut, and the uniform air rotating shaft follows the screw rod down under the action of gravity, and then the uniform air outlet device can move downward;

[0049] When it is necessary to adjust the angle of the uniform air outlet device, the uniform air outlet device can be adjusted through the angle adjustment handle. When the air guiding handle is adjusted to the appropriate angle, the uniform air outlet device is at the appropriate angle. At this time, it can be firmly fixed by passing the connecting bolt through the angle adjustment hole and the angle arc hole;

[0050] When it is necessary to adjust the height of the fixed flap, several fixed flaps are installed on the rotating shaft. The adjacent fixed flaps are fixed by installing bolts on the connecting holes. When it is necessary to reduce the height of the fixed flap, the corresponding fixed flap can be removed. When it is necessary to increase the height of the fixed flap, the corresponding fixed flap can be installed;

[0051] When it is necessary to adjust the left and right positions of the fixed flap, the positions of the left and right adjusting plates on the separation box housing are adjusted through the elongated holes to achieve the purpose of adjusting the left and right positions of the rotating shaft;

[0052] When it is necessary to adjust the angle of the fixed flap, the fixed flap is adjusted through the handle. When the pointing handle is adjusted to the appropriate angle, the fixed flap is at the appropriate angle. At this time, it can be firmly fixed by passing the connecting bolt through the fixing hole and the arc hole.

[0053] A vibration screening and air separation device and an air separation method made according to the above scheme can not only make the material be evenly distributed with a uniform thickness through the setting of the feeding unit, but also can achieve the primary selection of the material (garbage), laying a foundation for the subsequent air separation, and at the same time ensuring the accuracy of the air separation result; Further, the present invention adopts a uniform air distribution and air separation unit. This uniform air distribution and air separation unit overcomes the way of directly using a blower in the traditional technology, but increases the width of the air outlet and makes the air outlet pressure in a uniform state through the air box and the uniform air outlet device, so as to achieve high-efficiency and precise air separation of the material (garbage). On this basis, the present invention also sets relevant devices to achieve the purpose of adjusting the height and angle of the uniform air outlet device, so as to achieve the purpose of improving the air separation accuracy of the material (garbage) by selecting the blowing angle and position of the uniform air outlet device; Further, in order to meet the air separation requirements of different materials, the present invention sets the movable material screening unit to be able to adjust the height, angle and front and back positions of the fixed flap. The above design not only increases the types of screened materials, but also can cooperate with the uniform air outlet device to improve the accuracy of material (garbage) screening; It has the advantages of simple structure, reasonable design, being applicable to various types of materials (garbage), large processing capacity, being able to achieve the primary selection of materials and making the material thickness uniform, and being able to improve the material screening efficiency and accuracy by making the width of the uniform air outlet device wider, adjusting its angle and the uniform air pressure, and cooperating with the height and angle adjustable uniform air distribution and air separation unit to achieve the screening of different materials and improve the screening accuracy.

Detailed implementation manners

[0061] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0062] Refer to Figures 1-5:The present invention relates to a vibration screening and air separation device and an air separation method. The separation device includes: at least one housing unit; at least one cloth-feeding unit for enabling the material to advance at a uniform speed and with a uniform thickness; and at least one movable material screening unit disposed inside the housing unit and capable of adjusting the front-back position, height, and angle; at least one height- and angle-adjustable air distribution and air separation unit disposed between the cloth-feeding unit and the movable material screening unit; the cloth-feeding unit is a relaxation screen part, a cloth distributor part, or a combination of a relaxation screen part and a cloth distributor part. The main purpose of the cloth-feeding unit in the present invention is to enable the material to advance at a uniform speed and with a uniform thickness so as to facilitate the air separation of the material in subsequent processes. The above cloth-feeding unit can be adjusted according to the actual situation. For example, when the amount of material is large, the form of combining a relaxation screen part and a cloth distributor part can be adopted; when the amount of material is small and primary screening is required, the relaxation screen part can be used as the cloth-feeding unit; when the amount of material is small and primary screening is not required, the cloth distributor part can be used as the cloth-feeding unit. It should be noted that the width of the discharge port of the cloth distributor part and / or the relaxation screen part in the present invention is not greater than the width of the housing. The larger the width of this discharge port, the greater the amount of garbage processed per unit time. The width of the above discharge port should be the same as the air outlet width of the air outlet unit in the height- and angle-adjustable air distribution and air separation unit. Further, when ensuring the same air outlet pressure of the air outlet unit, it can effectively ensure the accuracy of material screening, so as to overcome the defect of small air outlet and small garbage processing capacity in the prior art. At the same time, by setting the movable material screening unit and its cooperation with the height- and angle-adjustable air distribution and air separation unit, the present invention can solve the defect that materials with different densities cannot be screened in the same air separation device.

[0063] Further, the cloth-feeding unit is a relaxation screen part, and the relaxation screen part includes a relaxation screen body 1 and a relaxation screen vibration motor 2 with an exciter connected to the relaxation screen body 1. In the present invention, using the relaxation screen part as the cloth-feeding unit can achieve the even distribution of the material and avoid the material entering the cloth distributor in a large amount and concentrated manner; and it can achieve the purpose of primary screening of the material. At the same time, the relaxation screen in the relaxation screen part has the characteristic of good elasticity, which can avoid the problem of the relaxation screen mesh being blocked due to overly complex materials.

[0064] Further, the cloth-feeding unit is a cloth distributor part, and the cloth distributor part includes a cloth distributor 3 and a cloth distributor vibration motor 4 with an exciter connected to the cloth distributor 3. The cloth distributor part in the present invention adopts the form of vibrating cloth-feeding, which can further level the garbage when the garbage processing amount is large, so as to achieve the flat spreading, uniform thickness, and uniform speed advancement of the garbage, laying a foundation for subsequent air separation.

[0065] Furthermore, the cloth unit includes a relaxation sieve part and a cloth feeder part. The relaxation sieve part is arranged at the front end and connected to the material inlet 5 of the housing unit. The discharge port of the relaxation sieve part is connected to the inlet of the cloth feeder part. An activatable material screening unit is arranged obliquely below the discharge port of the cloth feeder part. In the present invention, the widths of both the relaxation sieve part and the cloth feeder part are the same as the width of the housing 6 to solve the problem of small garbage treatment capacity; through the relaxation sieve part and the cloth feeder part, the problem of a large amount of garbage surging in simultaneously for air separation can be effectively prevented.

[0066] Furthermore, the housing unit includes a housing 6, a material inlet 5 arranged at the top of one side of the housing 6, a light material outlet 7 and a heavy material outlet 8 arranged at the bottom of the other side of the housing 6. An air return duct with an induced draft fan 9 is arranged at the end of the other side of the housing 6; through the above structure, the material and the separation air of the present invention can form a complete process to ensure the smooth progress of material separation.

[0067] When the cloth unit includes a relaxation sieve part, the housing 6 includes a relaxation sieve part housing and a separation box housing connected to the relaxation sieve part housing; the relaxation sieve part in the present invention can be used as a primary selection material or as an initial cloth feeder to prevent a large amount of garbage from surging in, so as to improve the material processing capacity of the present invention. The material processing capacity refers to the quantity and diversity of the materials.

[0068] A relaxation sieve underflow outlet 10 is arranged at the lower part of the relaxation sieve part housing corresponding to the bottom of the relaxation sieve body 1; by arranging the relaxation sieve underflow outlet 10, the material can be effectively selected initially.

[0069] When the cloth unit includes a cloth feeder part, a cloth feeder part, an activatable material screening unit and a height and angle adjustable uniform air air separation unit are arranged inside the separation box housing. This structure is mainly applicable to small amounts of garbage with different types. When the types of garbage are different, the activatable material screening unit and the height and angle adjustable uniform air air separation unit can be adjusted to screen the garbage.

[0070] Furthermore, the activatable material screening unit includes left and right adjusting plates 11 correspondingly arranged on both sides of the separation box housing. A rotating shaft 37 is arranged between the two left and right adjusting plates 11, and at least one fixable flap 12 is arranged on the rotating shaft 37; in the present invention, by increasing or decreasing the number of fixable flaps 12, the overall height of the fixable flap part can be adjusted.

A screw rod is provided at a position corresponding to the elongated hole 13 on the housing 6 in the present invention, and the movable material screening unit can be fixed through the cooperation of a nut and the screw rod; at the same time, a long hole for the movement of the rotation axis 37 is provided at a position corresponding to the rotation axis 37 on the housing 6; the above structural form can not only facilitate the front and back movement of the movable material screening unit, but also prevent the dust generated during the screening process from escaping.

[0072] Pointing handles 14 parallel to the fixable flap 12 are respectively provided at both ends of the rotation axis 37. A fixing hole 15 is provided in the middle of the pointing handle 14. A fixing plate 16 is provided at the top of the left and right adjusting plate 11. An arc-shaped hole 17 is provided at a position corresponding to the fixing hole 15 on the fixing plate 16; a connecting bolt is installed on the fixing hole 15 and the arc-shaped hole 17. Through the above structural arrangement, the angle of the fixable flap part can be adjusted and fixed. At the same time, when the position of the fixable flap part changes when it receives an impact, the arc-shaped hole 17 has a guiding and marking function, and the operator can timely reset it through manual adjustment.

[0073] Further, the width of the fixable flap 12 is adapted to the width inside the separation box. Connecting holes 18 for inserting bolts are respectively provided at the upper and lower parts of the fixable flap 12; a grip 19 is provided at the top of the pointing handle 14. The above arrangement can realize the screening of a large amount of materials (garbage), which corresponds to the width of the outlet of the upper cloth distributor unit and the uniform air outlet device 23. Preferably, the widths of the fixable flap 12, the outlet of the cloth distributor unit and the uniform air outlet device 23 are the same.

[0074] Further, the height and angle adjustable uniform air separation unit includes a centrifugal fan 20. The air outlet pipe of the centrifugal fan 20 is connected to the uniform air outlet device 23 through an air box 21 and a flexible connection pipe 22; through the above arrangement, the width of the air outlet can be increased and the air outlet pressure can be kept consistent to realize the accurate air separation of materials (garbage).

[0075] The bottom of the uniform air outlet device 23 is connected to the uniform air rotating shaft 24, and the two ends of the uniform air rotating shaft 24 pass through the two sides of the separation box shell and the height adjustment plate 25 connected to the outer wall of the separation box shell. The end of the uniform air rotating shaft 24 is provided with a uniform air pointing handle 26 parallel to the uniform air outlet device 23, and the middle of the uniform air pointing handle 26 is provided with an angle adjustment hole 27.

The height adjustment plate 25 enables the adjustment of the height of the uniform air outlet device 23 by providing a screw guide device.

[0076] Furthermore, a plurality of wind shields 33 are staggeredly arranged in the wind box 21; a plurality of air outlets 34 are evenly arranged in the uniform air outlet device 23; and an angle adjustment handle 35 is provided at the end of the uniform air direction handle 26. The above arrangement enables the air in the wind box 21 to be evenly discharged, avoiding the problem of high air pressure in the middle and low air pressure on both sides, which results in poor material sorting effect.

[0077] The present invention also provides an air selection method for a vibrating screening and air selection separation device, the air selection method including a screening method with a large amount of material, a screening method with a small amount of material and a variety of material types, and a screening method with a small amount of material;

[0078] a. The screening method for large amounts of material includes the following steps:

[0079] Step 1: When the material quantity is greater than 150t / h, the material enters the relaxation screen part through the material feed port 5 and passes through the relaxation screen body 1. The relaxation screen vibration motor 2 with an exciter starts, driving the material to disperse in the relaxation screen body 1 and move forward to the distributor part at a uniform speed. The distributor vibration motor 4 with an exciter starts to further disperse the material in the distributor until the material thickness is uniform, and at the same time, it is discharged from the distributor part at a uniform speed.

[0080] When the amount of material is large and the types of materials are many, the smaller materials can be screened by the relaxation screen body 1, and the undersize materials are discharged through the relaxation screen undersize material outlet 10; the oversize materials are discharged through the discharge port of the relaxation screen part, the feed port of the distributor part and the discharge port of the distributor part;

[0081] The above process realizes the primary selection of materials and enables the materials to have uniform thickness and move forward at a uniform speed, creating conditions for the air separation of the materials;

[0082] Step 2: The materials are discharged from the discharge port of the distributor part. At the same time, the centrifugal fan 20 is started. The sorting air enters the air box 21 through the air outlet pipe. Under the action of several staggered baffle plates 33, the sorting air is evenly distributed. The evenly distributed sorting air enters the air outlet 34 in the uniform air outlet device 23 through the flexible connection pipe 22 and acts on the materials to realize the air separation of the materials; The air after air separation is discharged through the return air pipe with the induced draft fan 9;

[0083] In the above process, it is ensured that the air volume in the air outlet 34 is uniform, providing guarantee for the accurate screening of the materials;

[0084] Step 3: When the sorting air acts on the materials, the heavy substances in the materials have a smaller parabola due to their larger specific gravity, and the heavy substances fall into the heavy material outlet 8 inside the fixed flap 12; The light substances in the materials have a larger parabola due to their smaller specific gravity, and the light substances fall into the light material outlet 7 outside the fixed flap 12 to complete the screening;

[0085] b. The screening method for a small amount of materials and many types of materials includes the following steps:

[0086] Step 1: When the amount of materials is no more than 150 t / h and there are many types of materials, the materials enter the relaxation screen part through the material inlet 5 and pass through the relaxation screen body 1. The relaxation screen vibration motor 2 with an exciter is started. The relaxation screen body 1 screens the smaller materials. The undersize materials are discharged through the undersize material outlet 10 of the relaxation screen. The oversize materials move forward with uniform thickness and at a uniform speed at the upper part of the relaxation screen body 1, and the oversize materials are discharged through the discharge port of the relaxation screen part, the feed port of the distributor part and the discharge port of the distributor part;

[0087] The above process realizes the primary selection of materials and enables the materials to have uniform thickness and move forward at a uniform speed, creating conditions for the air separation of the materials;

[0088] Step 2: The materials are discharged from the discharge port of the distributor part. At the same time, the centrifugal fan 20 is started. The sorting air enters the air box 21 through the air outlet pipe. Under the action of several staggered baffle plates 33, the sorting air is evenly distributed. The evenly distributed sorting air enters the air outlet 34 in the uniform air outlet device 23 through the flexible connection pipe 22 and acts on the materials to realize the air separation of the materials; The air after air separation is discharged through the return air pipe with the induced draft fan 9;

[0089] In the above process, it is ensured that the air volume in the air outlet 34 is uniform, providing guarantee for the accurate screening of the materials;

[0090] Step 3: When the air separation air acts on the material, the heavy substances in the material have a large specific gravity and a small parabola, and the heavy substances fall into the heavy material outlet 8 inside the fixed flap 12; the light substances in the material have a small specific gravity and a large parabola, and the light substances fall into the light material outlet 7 outside the fixed flap 12, completing the screening;

[0091] c. The screening method for a small amount of material includes the following steps:

[0092] Step 1: When the material volume is not greater than 150 t / h, the material enters the distributor 3 in the distributor section through the material inlet 5. The vibration motor 4 of the distributor with an exciter starts to vibrate the material to make the thickness of the material in the distributor uniform, and at the same time, the material is discharged evenly from the outlet of the distributor section at a constant speed;

[0093] The above process makes the material advance with uniform thickness and constant speed, creating conditions for the air separation of the material;

[0094] Step 2: The material is discharged from the outlet of the distributor section. At the same time, the centrifugal fan 20 is started, and the separation air enters the air box 21 through the air outlet pipe. Under the action of a number of staggered baffle plates 33, the separation air is evenly divided. The evenly divided separation air enters the air outlet 34 in the uniform air outlet device 23 through the flexible connection pipe 22 and acts on the material to achieve the air separation of the material; the air after air separation is discharged through the return air pipe with an induced draft fan 9;

[0095] In the above process, it is ensured that the air volume from the air outlet 34 is uniform, providing guarantee for the accurate screening of the material;

[0096] Step 3: When the air separation air acts on the material, the heavy substances in the material have a large specific gravity and a small parabola, and the heavy substances fall into the heavy material outlet 8 inside the fixed flap 12; the light substances in the material have a small specific gravity and a large parabola, and the light substances fall into the light material outlet 7 outside the fixed flap 12, completing the screening;

[0097] Due to the different types and densities of the materials, it is necessary to adjust the height and angle of the uniform air outlet device 23, adjust the height and left - right and angle of the fixed flap 12, and adjust the uniform air outlet device 23 and the fixed flap 12 simultaneously;

[0098] When it is necessary to adjust the height of the uniform air outlet device 23, an operator makes the screw rod 31 move upward by adjusting the adjusting nut 32. The screw rod 31 pushes the air - equalizing rotating shaft 24, causing the air - equalizing rotating shaft 24 to displace upward, and then the uniform air outlet device 23 can move upward; the operator makes the screw rod 31 move downward by adjusting the adjusting nut 32, and the air - equalizing rotating shaft 24 moves downward with the screw rod 31 under the action of gravity, and then the uniform air outlet device 23 can move downward;

[0099] When it is necessary to adjust the angle of the uniform air outlet device 23, the uniform air outlet device 23 can be adjusted through the angle adjustment handle 35. When the air distribution pointing handle 26 is adjusted to the appropriate angle, the uniform air outlet device 23 is at the appropriate angle. At this time, it can be firmly fixed by passing the connecting bolt through the angle adjustment hole 27 and the angle arc hole 29;

[0100] When it is necessary to adjust the height of the fixable flap 12, a number of fixable flaps 12 are installed on the rotating shaft 37. The adjacent fixable flaps 12 are fixed by installing bolts through the connecting holes 18. When it is necessary to lower the height of the fixable flap 12, the corresponding fixable flap 12 can be removed. When it is necessary to increase the height of the fixable flap 12, the corresponding fixable flap 12 can be installed;

[0101] When it is necessary to adjust the left and right positions of the fixable flap 12, the positions of the left and right adjusting plates 11 on the separation box housing are adjusted through the elongated holes 13 to achieve the purpose of adjusting the left and right positions of the rotating shaft 37;

[0102] When it is necessary to adjust the angle of the fixable flap 12, the fixable flap 12 is adjusted through the handle 19. When the pointing handle 14 is adjusted to the appropriate angle, the fixable flap 12 is at the appropriate angle. At this time, it can be firmly fixed by passing the connecting bolt through the fixing hole 15 and the arc hole 17.

[0103] The essence of the present invention lies in reducing or eliminating the form of manual sorting cooperation to meet the sorting of different types of garbage. When the different types refer to the quantity of materials (garbage) and involve various materials (garbage) with different densities, the device and method of the present invention can ensure normal operation and achieve a high sorting accuracy at the same time. The cloth-feeding unit of the present invention not only has the function of making the materials advance at a uniform speed and with a uniform thickness, but also can widen the discharge channel to improve the ability to process materials (garbage). In order to cooperate with the widening of the above-mentioned discharge channel, the present invention improves the height- and angle-adjustable air-uniforming air separation unit. The main purposes of the improvement mainly include increasing the air outlet width and keeping the air outlet pressure consistent. The present invention overcomes the drawbacks of the traditional method of increasing the air outlet pressure (when the air outlet pressure cannot be kept consistent, there will be a phenomenon that the air outlet pressure in the middle is large and the pressure on both sides is small, resulting in a poor air separation accuracy problem for the materials). By increasing the air outlet width, that is, the air blows out together at the same position inside the shell and the air outlet pressure is kept consistent, the present invention not only overcomes the above technical problems but also lays a foundation for improving the air separation accuracy and efficiency. Further, the present invention realizes air separation for materials (garbage) with different densities by setting up a movable material screening unit and adjusting it in terms of front-back, height, and angle, etc., to improve the air separation accuracy. The combination of the above structures and methods can be applied to domestic garbage, construction waste, decoration waste, etc., so that various materials or garbage can be sorted by the same equipment, reducing or eliminating manual sorting, reducing labor intensity, improving the screening accuracy and efficiency; at the same time, reducing the investment cost and operating cost. It should be noted that when the cloth-feeding unit in the present invention includes a relaxation screen part and a cloth-feeding part, the quantity of materials (or garbage) that can be processed is relatively large, and the primary selection of materials can be realized (that is, there can be a relatively large variety of material types). When the cloth-feeding unit in the present invention is a relaxation screen part, the quantity of materials (or garbage) that can be processed is relatively small, and the primary selection of materials can be realized (that is, there can be a relatively large variety of material types). When the cloth-feeding unit in the present invention is a cloth-feeding part, the quantity of materials (or garbage) that can be processed is relatively small, mainly for dealing with the situation where the material types are relatively single. When the present invention refers to a relatively single material type, it mainly means that there are two material types, and when it refers to a relatively large variety of material types, it means that there are three or more material types. In addition, in order to ensure the uniformity of the air outlet pressure, there can be several soft connection pipes 22 in the present invention to evenly distribute the air in the air box 21, and at the same time, several soft connection pipes 22 are connected to several air outlets 34 to ensure the uniformity of the air outlet pressure.In addition, the adjustment in the present invention is determined according to the specific working conditions. For example, for materials with relatively large densities of both materials, the height of the air distribution unit for uniform air can be increased, and the air can be blown obliquely upwards. At the same time, the height of the movable material screening unit can be decreased, and air separation can be achieved at the discharge port of the distributor, so as to increase the parabolic angle of the lighter material. At the same time, the height of the movable material screening unit can be decreased, and the movable material screening unit can be moved towards the heavy material outlet and fixed; when the density difference between the two materials is relatively large, the height of the adjustable air distribution unit for uniform air can be decreased, and horizontal or obliquely downward blowing can be adopted. At the same time, the height of the movable material screening unit can be decreased, etc.; for materials with relatively small densities of both materials, the height of the adjustable air distribution unit for uniform air can be adjusted to adopt horizontal or obliquely downward blowing according to the actual situation. At the same time, the height of the movable material screening unit can be increased to quickly separate the materials and prevent the problem of reduced sorting accuracy caused by the influence of air flow. The above examples are not limitations on the present invention. They are only for illustration. The specific adjustment of the movable material screening unit and the adjustable air distribution unit for uniform air needs to be determined according to the working conditions during actual production.

Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples.

[0113] The present invention also provides a wind separation method for a vibration screening and wind separation device. The wind separation method includes a screening method for a large amount of materials. The screening method for a large amount of materials includes the following steps:

[0114] Step 1: When the material quantity is greater than 150 t / h, the material enters the relaxation screen part through the material inlet 5 and passes through the relaxation screen body 1. The relaxation screen vibration motor 2 with an exciter is started, driving the material to disperse and move forward evenly in the relaxation screen body 1 to the distributor part.

[0117] Step 2: The material is discharged from the discharge port of the distributor part. At the same time, the centrifugal fan 20 is started. The sorting wind enters the bellows 21 through the air outlet pipe. Under the action of a number of staggered wind baffle plates 33, the sorting wind is evenly divided.

[0118] In the above process, it is ensured that the air output from the air outlets 34 is uniform, providing guarantee for the accurate screening of the material;

[0119] Step 3: When the sorting wind acts on the material, the heavy substances in the material have a small parabola due to their large specific gravity, and the heavy substances fall into the heavy material outlet 8 inside the fixed flap 12; the light substances in the material have a large parabola due to their small specific gravity, and the light substances fall into the light material outlet 7 outside the fixed flap 12, completing the screening;

[0121] When it is necessary to adjust the height of the uniform air outlet device 23, manually make the lead screw 31 move upward by adjusting the nut 32. The lead screw 31 pushes the uniform air rotation shaft 24, causing the uniform air rotation shaft 24 to displace upward, so that the uniform air outlet device 23 can move upward; manually make the lead screw 31 move downward by adjusting the nut 32, and the uniform air rotation shaft 24 moves downward with the lead screw 31 under the action of gravity, so that the uniform air outlet device 23 can move downward;

[0134] The present invention also provides a wind selection method of a vibrating screening and wind selection separation device, the wind selection method includes a screening method for a small amount of material and a large number of material types, and the screening method for a small amount of material and a large number of material types includes the following steps:

[0135] Step 1: When the material quantity is not more than 150t / h and there are many types of materials, the material enters the relaxation screen part through the material feed port 5 and passes through the relaxation screen body 1. The relaxation screen vibration motor 2 with an exciter is started, and the relaxation screen body 1 screens the smaller materials. The undersize materials are discharged through the relaxation screen undersize material outlet 10. The oversize materials are uniformly thick and move forward at a uniform speed on the upper part of the relaxation screen body 1. The oversize materials are discharged through the discharge port of the relaxation screen part, the feed port of the distributor part, and the discharge port of the distributor part;

[0136] The above process realizes the primary selection of materials and makes the materials uniform in thickness and at a uniform speed, thus creating conditions for the wind selection of materials;

[0137] Step 2: The material is discharged from the discharge port of the distributor, and the centrifugal fan 20 is started at the same time. The sorting air enters the wind box 21 through the air outlet duct. The sorting air is evenly distributed under the action of a plurality of staggered wind shields 33.

The air after air selection is discharged through the return air duct with the induced draft fan 9.

[0138] The above process ensures that the air volume in the air outlet 34 is uniform, providing a guarantee for accurate screening of the material;

[0139] Step 3: When the air separation wind acts on the material, the heavy materials in the material fall into the heavy material outlet 8 on the inner side of the fixed flap 12 due to their large specific gravity and small parabola; the light materials in the material fall into the light material outlet 7 on the outer side of the fixed flap 12 due to their small specific gravity and large parabola, thus completing the screening;

[0141] When it is necessary to adjust the height of the uniform air outlet device 23, manually turn the adjusting nut 32 to make the lead screw 31 move upward. The lead screw 31 pushes the air equalizing rotating shaft 24, causing the air equalizing rotating shaft 24 to displace upward, so that the uniform air outlet device 23 can move upward; manually turn the adjusting nut 32 to make the lead screw 31 move downward, and the air equalizing rotating shaft 24 moves downward along with the lead screw 31 under the action of gravity, so that the uniform air outlet device 23 can move downward;

[0142] When it is necessary to adjust the angle of the uniform air outlet device 23, the uniform air outlet device 23 can be adjusted through the angle adjustment handle 35. When the air equalizing pointing handle 26 is adjusted to the appropriate angle, the uniform air outlet device 23 is at the appropriate angle. At this time, it can be firmly fixed by passing the connecting bolt through the angle adjustment hole 27 and the angle arc hole 29;

[0143] When it is necessary to adjust the height of the fixed flap 12, a number of fixed flaps 12 are installed on the rotating shaft 37.

[0145] When it is necessary to adjust the angle of the fixed flap 12, the fixed flap 12 is adjusted through the handle 19. When the pointing handle 14 is adjusted to the appropriate angle, the fixed flap 12 is at the appropriate angle. At this time, it can be firmly fixed by passing the connecting bolt through the fixing hole 15 and the arc hole 17.

[0154] The present invention also provides a wind separation method for a vibration screening and wind separation device. The wind separation method includes a screening method for a small amount of materials. The screening method for a small amount of materials includes the following steps:

[0155] Step 1: When the amount of materials is not greater than 150 t / h, the materials enter the distributor 3 in the distributor section through the material inlet 5. The vibration motor 4 of the distributor with an exciter starts to vibrate the materials to make the thickness of the materials in the distributor uniform, and at the same time, the materials are discharged at a uniform speed from the outlet of the distributor section.

[0156] The above process makes the materials advance with uniform thickness and speed, creating conditions for the wind separation of the materials.

[0157] Step 2: The materials are discharged from the outlet of the distributor section. At the same time, the centrifugal fan 20 is started. The sorting wind enters the bellows 21 through the air outlet pipe. Under the action of a number of wind baffle plates 33 arranged in a staggered manner, the sorting wind is evenly divided. The evenly divided sorting wind enters the air outlets 34 in the uniform air outlet device 23 through the flexible connection pipe 22 and acts on the materials to realize the wind separation of the materials; the wind after the wind separation is discharged through the return air pipe with an induced draft fan 9.

[0158] In the above process, it is ensured that the air volume discharged from the air outlets 34 is uniform, providing guarantee for the accurate screening of the materials.

[0159] Step 3: When the sorting wind acts on the materials, the heavy substances in the materials have a small parabola due to their large specific gravity, and the heavy substances fall into the heavy material outlet 8 inside the fixed flap 12; the light substances in the materials have a large parabola due to their small specific gravity, and the light substances fall into the light material outlet 7 outside the fixed flap 12 to complete the screening.

[0160] Due to the different types and densities of the materials, it is necessary to adjust the height and angle of the uniform air outlet device 23, adjust the height and angle of the fixed flap 12 left and right, and adjust the uniform air outlet device 23 and the fixed flap 12 simultaneously;

[0161] When it is necessary to adjust the height of the uniform air outlet device 23, manually make the screw rod 31 move upward by adjusting the nut 32. The screw rod 31 pushes the air equalizing rotating shaft 24 to make the air equalizing rotating shaft 24 generate an upward displacement, and the uniform air outlet device 23 can be moved upward; manually make the screw rod 31 move downward by adjusting the nut 32. The air equalizing rotating shaft 24 moves downward with the screw rod 31 under the action of gravity, and the uniform air outlet device 23 can be moved downward.

[0162] When it is necessary to adjust the angle of the uniform air outlet device 23, the uniform air outlet device 23 can be adjusted through the angle adjustment grip 35. When the air distribution pointing handle 26 is adjusted to an appropriate angle, the uniform air outlet device 23 is at the appropriate angle. At this time, it can be firmly fixed by passing the connecting bolt through the angle adjustment hole 27 and the angle arc hole 29;

[0163] When it is necessary to adjust the height of the fixed flap 12, a plurality of fixed flaps 12 are installed on the rotating shaft 37. The adjacent fixed flaps 12 are fixed by installing bolts on the connecting holes 18. When it is necessary to lower the height of the fixed flap 12, the corresponding fixed flap 12 can be removed. When it is necessary to increase the height of the fixed flap 12, the corresponding fixed flap 12 can be installed;

[0164] When it is necessary to adjust the left and right positions of the fixed flap 12, the position of the left and right adjustment plates 11 on the separation box housing is adjusted through the elongated holes 13 to achieve the purpose of adjusting the left and right positions of the rotating shaft 37;

[0165] When it is necessary to adjust the angle of the fixed flap 12, the fixed flap 12 is adjusted through the grip 19. When the pointing handle 14 is adjusted to an appropriate angle, the fixed flap 12 is at the appropriate angle. At this time, it can be firmly fixed by passing the connecting bolt through the fixing hole 15 and the arc hole 17.
