Description

Technical Field

[0001] The present invention relates to the field of waste treatment, and in particular to a box-type wind-powered sorting device for solid waste treatment. Background Art

[0002] Construction waste refers to the general term for slag, waste concrete, waste bricks and other wastes generated by people in the production activities of the construction industry such as demolition, construction, decoration and repair. According to the composition, construction waste can be divided into slag, concrete blocks, broken stones, brick and tile fragments, waste mortar, mud, asphalt blocks, waste plastics, waste metals, waste bamboo and wood, foam, etc.

[0003] Construction waste has corresponding hazards, which are specifically manifested in the following aspects: random stacking of construction waste can easily cause safety hazards, construction waste seriously pollutes water resources, and construction waste affects air quality. With the research of construction waste, construction waste currently has the following applications.

[0004] (1) Using waste construction concrete and waste bricks and stones to produce coarse and fine aggregates can be used to produce concrete and mortar of corresponding strength grades or to prepare building materials such as blocks, wall panels, and floor tiles. After adding curing materials, coarse and fine aggregates can also be used as road pavement base.

[0005] (2) Use waste bricks and tiles to produce aggregates, which can be used to produce recycled bricks, blocks, wall panels, floor tiles and other building materials.

[0006] (3) The slag can be used for road construction, pile foundation filling, foundation, etc.

[0007] (4) For abandoned wood construction waste, wood that has not been obviously damaged can be directly reused for reconstruction, and wood components that are severely damaged can be used as raw materials for wood-based recycled boards or papermaking, etc.

[0008] (5) Abandoned road asphalt mixture can be directly used in recycled asphalt concrete in appropriate proportions.

[0009] (6) Waste road concrete can be processed into recycled aggregate for the preparation of recycled concrete.

[0010] (7) Scrap steel, scrap steel bars and other scrap metal materials can be directly reused or recycled.

[0011] (8) Construction waste such as waste glass, waste plastic, waste ceramics, etc. should be utilized according to the specific situation.

[0012] From the above applications of construction waste, it can be seen that the application of construction waste in different places requires different materials. Therefore, the first task is to sort the construction waste so that the sorted materials can be made into various materials.

[0013] Construction waste can be classified by weight into heavy waste with heavier mass and light waste with lighter mass. Therefore, the first sorting is usually to separate heavy waste from light waste. The equipment usually used to separate heavy waste from light waste is air separation equipment, such as the air separator disclosed in CN114522881A. The working principle of the air separator is: the construction waste is put into the input port of the air separation equipment, and the construction waste falls onto the conveying mechanism. When the construction waste is transferred from the conveying mechanism to the separation drum, the heavy waste automatically falls to the discharge port, and the light waste enters the sedimentation chamber under the joint action of the jet assembly and the separation drum, and the ultra-light waste is taken away by the airflow generated by the vacuum pump.

[0014] The above-mentioned air separator has the following defects:

[0015] First, the conveying mechanism uses a belt conveyor mechanism. Since the distance between the output end of the conveying mechanism and the separation roller is relatively close, the dust floats around in the box, causing the dust to adhere to the belt, which will cause the efficiency of the belt conveyor mechanism to decrease. When the thickness of the dust reaches a certain level, the belt conveyor mechanism will slip.

[0016] Second, since the angle of the jet assembly needs to be adjusted, an inner bracket and a swing arm are set in the box, and the jet assembly is connected to the inner bracket and the swing arm respectively, and the swing arm is connected to the drum bracket supporting the separation drum. Since the swing arm will pass through the falling area of ​​heavy garbage, although the swing arm is located on both sides of the separation drum, there is no fixed trajectory for the falling of heavy garbage. Therefore, there is a high probability that the swing arm will be hit by heavy garbage. Once the swing arm breaks, the jet assembly will fail to blow light garbage, which will eventually lead to the failure of light and heavy garbage separation.

[0017] Third, light garbage often contains a lot of dust, light materials (plastics, foams), small particles and other substances. When these substances pass through the vacuum pump, the light materials among them are easy to cause the vacuum pump to be blocked. Although some air separation equipment currently has filters installed in the sedimentation chamber, the filters are composed of multiple chains, but the chains can only block light materials, and cannot filter small particles, which will still cause the vacuum pump to be blocked. In addition, light materials are easy to be entangled in the chain and need to be cleaned regularly. Summary of the invention

[0018] The invention provides a box-type wind-powered sorting device for solid waste treatment, which can avoid wind-separation failure.

[0019] The technical solutions to the above technical problems are as follows:

[0020] A box-type wind sorting equipment for solid waste treatment comprises a front box body, a first belt conveyor mechanism, a separation component, a jet component, and a sedimentation box body. The first belt conveyor mechanism, the separation component, and the jet component are all installed inside the front box body. The sedimentation box body is connected to the front box body, and the sedimentation box body is located downstream of the separation component. The front box body is provided with a first discharge port, and the first discharge port is located below the output end of the first belt conveyor mechanism. The separation component is a rotary separation component, and the separation component is located downstream of the first belt conveyor mechanism. The jet component comprises a fan and a nozzle. The fan is connected to the nozzle, and the nozzle is located below the first belt conveyor mechanism. The nozzle cooperates with the separation component to separate light garbage from heavy garbage. The jet component also comprises a first connecting seat, a second connecting seat, a third connecting seat, a fourth connecting seat, and an angle adjustment assembly. The first connecting seat and the second connecting seat are respectively fixed to the nozzle, and the third connecting seat and the fourth connecting seat are respectively fixed to the first belt conveyor mechanism. The first connecting seat is hinged to the third connecting seat, the second connecting seat is connected to one end of the angle adjustment assembly, and the other end of the angle adjustment assembly is connected to the fourth connecting seat.

[0021] In the present invention, the third connection seat and the fourth connection seat are fixed to the first belt conveyor mechanism, the first connection seat is hinged to the third connection seat, the second connection seat is connected to one end of the angle adjustment component, and the other end of the angle adjustment component is connected to the fourth connection seat. This structure prevents the angle adjustment component and other parts from passing through the space between the first belt conveyor mechanism and the separation component to be connected to the separation component, thereby preventing the material output from the first belt conveyor mechanism from hitting the angle adjustment component, preventing the jet component from being damaged, and ensuring that the separation effect of the jet component on heavy garbage and light garbage is always in an effective state.

DETAILED DESCRIPTION

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] like Figures 1 to 16 As shown, the box-type wind sorting equipment for solid waste treatment of the present invention includes a front box body A, a first belt conveyor mechanism B, a separation component C, an injection component D, a sedimentation box body E, a second belt conveyor mechanism F, and a scraping material separator G. The various parts and the relationship between them are described in detail below.

[0048] The first belt conveyor B, the separation assembly C, and the jet assembly D are all installed inside the front box A. The sedimentation box E is connected to the front box A. The sedimentation box E is located downstream of the separation assembly C. The front box A is provided with a first discharge port 11, which is located below the output end of the first belt conveyor B and between the first belt conveyor B and the separation assembly C. The front box A is provided with a first feed port 12, which is above the output end of the first belt conveyor B.

[0049] The first belt conveying mechanism B includes a mounting bracket 21, a belt transmission mechanism 22, and an inner scraping assembly 23 for cleaning the inner surface of the belt transmission mechanism 22. The belt transmission mechanism 22 is mounted on the mounting bracket 21, and the inner scraping assembly 23 is fixed to the mounting bracket 21. The inner scraping assembly 23 cooperates with the inner surface of the belt transmission mechanism 22. One end of the mounting bracket 21 is hinged to the front box A, and the other end of the mounting bracket 21 is connected to an adjustment frame 27. The adjustment frame 27 is used to adjust the height of the output end of the first belt conveying mechanism B. The height of the output end cooperates with the separation assembly C to achieve a better separation effect of light and heavy garbage. The structure of the adjustment frame 27 can refer to the first adjustment mechanism in CN114522881A.

[0050] The inner scraper assembly 23 includes an inner scraper bracket 23a, an inner scraper 23b, and an elastic connecting plate 23c. The inner scraper bracket 23a is polygonal. In the present embodiment, the inner scraper bracket 23a is a triangle. The shape of the inner scraper bracket 23a is preferably an isosceles triangle. One of the angles of the isosceles triangle points in a direction opposite to the belt movement direction in the belt transmission mechanism 22 with which it cooperates. The inner scraper 23b is fixed to the inner scraper bracket 23a. The inner scrapers 23b are respectively installed on the two waists of the isosceles triangle. When garbage adheres to the belt, the garbage on the belt is scraped off by the inner scraper 23b to separate the garbage from the belt. The separated garbage falls from both sides of the belt to the bottom of the box A under the obstruction of the inner scraper assembly 23.

[0051] The two ends of the elastic connecting plate 23c are bent relative to the middle to form a first bending portion and a second bending portion, the first bending portion is bent in the first direction, and the second bending portion is bent in the second direction, the first direction and the second direction are opposite, one end of the elastic connecting plate 23c is fixed to the inner scraping bracket 23a, and after the other end of the elastic connecting plate 23c is fixed to the mounting bracket 21, the middle part and the second bending portion of the elastic connecting plate 23c are spaced from the mounting bracket 21, when the pressure on the elastic connecting plate 23c is too large, for example, when the garbage accumulated on the inner surface of the belt is too thick, the elastic connecting plate 23c is swung, thereby scraping off a part of the garbage, and after multiple scraping actions, all the garbage accumulated on the belt surface can be scraped off. This structure can avoid reducing the conveying speed of the belt transmission mechanism 22, and ensure that the conveying efficiency of the belt transmission mechanism 22 will not be reduced due to scraping obstruction.

[0052] By scraping and cleaning the inner surface of the belt through the inner scraper assembly 23, the thickness of garbage accumulated on the inner surface of the belt is greatly reduced, thereby avoiding the belt slipping and ensuring the conveying efficiency of the first belt conveying mechanism B.

[0053] The first belt conveyor mechanism B further includes a buffer bed 24, which is fixed to the mounting bracket 21. The buffer bed 24 is located in the belt transmission mechanism 22 and cooperates with the inner surface of the belt transmission mechanism 22. The buffer bed 24 is located directly below the first feed inlet 12. After the garbage is input from the first feed inlet 12, it falls onto the belt of the belt transmission mechanism 22. Since the buffer bed 24 supports the belt transmission mechanism 22, the impact force on the belt is reduced. The buffer bed 24 is composed of a longitudinal beam and a buffer component installed on the longitudinal beam. The buffer component can be composed of an upper support plate, a lower support plate and a spring. The spring is located between the upper support plate and the lower support plate, and one end of the spring cooperates with the upper support plate, and the other end of the spring cooperates with the lower support plate. The upper support plate cooperates with the belt in the belt transmission mechanism 22, and the lower support plate is fixed to the longitudinal beam.

[0054] The first belt conveying mechanism B further includes an external scraping mechanism for cleaning the outer surface of the belt transmission mechanism 22, the external scraping mechanism including a knife frame 25 and an external scraper 26, the knife frame 25 is located at the end of the belt transmission mechanism 22 and is fixed to the mounting bracket 21, and the external scraper 26 is fixed to the knife frame 25. By scraping and cleaning the outer surface of the belt through the external scraping mechanism, the thickness of garbage accumulated on the outer surface of the belt is greatly reduced, and the unnecessary weight on the belt transmission mechanism 22 is reduced, so that the conveying efficiency of the first belt conveying mechanism B is guaranteed.

[0055] The separation component C is a rotary separation component, which is located downstream of the first belt conveying mechanism B. The separation component C includes a bearing seat assembly 31, a separation roller 32, a driver 33, a material baffle plate 34, a wind shield plate 35, and a fastener 36. The two ends of the separation roller 32 are respectively connected to the bearing seat assembly 31. The bearing seat assembly 31 consists of a bearing seat and a bearing installed on the bearing seat. The driver 33 is installed on the bearing seat in the bearing seat assembly 31. The two ends of the separation roller 32 are respectively connected to the bearings in the bearing seat assembly 31. The driver 33 is connected to the separation roller 32, and the material baffle plate 34 is connected to the bearing seat assembly 31.

[0056] The baffle plate 34 cooperates with the separation drum 32 to prevent light garbage from splashing. The wind shield 35 is connected to the baffle plate 34 by fasteners 36. The baffle plate 34 is located on both sides of the separation drum 32, and the wind shield 35 is located above the separation drum 32. Since the airflow ejected by the jet assembly D is inclined upward, the height of the dust can be reduced by blocking the airflow through the baffle plate 34 and the wind shield 35, so that the dust or light garbage can be settled in the sedimentation box E as soon as possible.

[0057] The material baffle plate 34 includes a side sealing plate 34a and an arc-shaped baffle plate 34b. The side sealing plate 34a is located outside the axial end surface of the separation drum 32, the side sealing plate 34a is fixed to the bearing seat assembly 31, the arc-shaped baffle plate 34b is located above the separation drum 32, the arc-shaped baffle plate 34b is fixed to the side sealing plate 34a, and the side sealing plate 34a is provided with an arc-shaped mounting hole 34c. The fastener 36 passes through the arc-shaped mounting hole 34c and is connected to one end of the windshield plate 35, and the other end of the windshield plate 35 is hinged to the side sealing plate 34a. This structure can adjust the angle of the windshield plate 35 according to the angle of the airflow sprayed by the jet assembly D, so that the windshield plate 35 can achieve the best effect of blocking the airflow.

[0058] The jet assembly D includes a fan 41 and a nozzle 42. The fan 41 is connected to the nozzle 42. The nozzle 42 is located below the first belt conveyor mechanism B. The nozzle 42 cooperates with the separation assembly C to separate light garbage from heavy garbage. Among the garbage output from the first belt conveyor mechanism B, the heavy garbage falls to the first discharge port 11, and the light garbage moves toward the separation assembly C under the action of the airflow ejected from the nozzle 42. Most of the light garbage moves toward the sedimentation box E along with the separation drum 32 under the rotation of the separation drum 32.

[0059] The jet assembly D also includes a first connecting seat 43, a second connecting seat 44, a third connecting seat 45, a fourth connecting seat 46, and an angle adjustment assembly 47. The first connecting seat 43 and the second connecting seat 44 are respectively fixed to the nozzle 42, and the third connecting seat 45 and the fourth connecting seat 46 are respectively fixed to the first belt conveying mechanism B. The third connecting seat 45 and the fourth connecting seat 46 are respectively fixed to the lower part of the mounting bracket 21. The first connecting seat 43 is hinged to the third connecting seat 45, the second connecting seat 44 is connected to one end of the angle adjustment assembly 47, the second connecting seat 44 is hinged to one end of the angle adjustment assembly 47, and the other end of the angle adjustment assembly 47 is connected to the fourth connecting seat 46. A plurality of mounting holes are provided on the fourth connecting seat 46. The angle adjustment assembly 47 is hinged to one of the mounting holes as needed, so that the angle of the nozzle 42 can be adjusted as needed.

[0060] The jet assembly D further includes a baffle 48, one end of which is fixed to the nozzle 42, and the other end of which extends toward the first discharge port 11. The baffle 48 can block the light garbage, greatly reducing the movement of the light garbage toward the first belt conveyor B, thereby reducing the accumulation of light garbage on the inner surface of the belt in the first belt conveyor B.

[0061] The angle adjustment assembly 47 includes an intermediate connecting frame 47a and a screw rod 47b. The two ends of the intermediate connecting frame 47a are respectively provided with threaded holes, and a clearance hole 47c is provided in the middle of the intermediate connecting frame 47a. The two ends of the intermediate connecting frame 47a are respectively threadedly connected to one end of a screw rod 47b. The other end of each screw rod 47b is a fork-shaped portion 47d, wherein the fork-shaped portion 47d of one screw rod 47b is hinged to the second connecting seat 44, and the fork-shaped portion of the other screw rod 47b is hinged to the fourth connecting seat 46. The angle of the nozzle 42 can also be adjusted by the angle adjustment assembly 47 itself.

[0062] The present invention also includes a second belt conveyor F and a scraper-type material separator G for separating light materials. The second belt conveyor F is located in the sedimentation box E. A second discharge port 51 is provided at the lower part of the sedimentation box E.

The function of the first inner scraping assembly 63 is the same as that of the inner scraping assembly 23, and the function of the first outer scraping assembly 64 is the same as that of the outer scraping mechanism in the first belt transmission mechanism B, which will not be repeated here.

[0064] The second belt transmission mechanism F further includes a chute 65, which is disposed above the first belt transmission mechanism 62 and fixed to the first mounting bracket 61, and the chute 65 is respectively matched with the separation component C and the first belt transmission mechanism 62.

[0075] One end of the support component is fixed to the scraping component 77a, a groove is provided on the elastic colloid 77b, and the other end of the support component matches with the groove on the elastic colloid 77b. The support component includes a tubular component 77c, a support plate 77d, a support portion 77e, and a convex strip 77f. One end of the support plate 77d is fixed to the tubular component 77c, and the support portion 77e is fixed to the other end of the support plate 77d. There is an angle between the support portion 77e and the support plate 77d, and the support portion 77e is inclined relative to the support plate 77d. The scraping component 77a is fixed to the support portion 77e, one end of the convex strip 77f is fixed to the tubular component 77c, and the other end of the convex strip 77f matches with the groove on the elastic colloid 77b.

[0076] The working process of the scraper type material separator is as follows: light garbage enters the housing 71 through the input port 72, and the negative pressure generated by the air extraction component causes the airflow and most of the fine objects such as dust to pass through the air vents. Light materials (plastics, foam, etc.) that cannot pass through the air vents will adhere to the inner wall surfaces of the lower housing 71a and the upper housing 71b, and dust materials that have not passed through the ventilation holes 74 will also adhere to the inner wall surfaces of the lower housing 71a and the upper housing 71b. The reduction motor 75e is started to work, and the reduction motor 75e is turned on. The output torque of e drives the rotating shaft 75f to rotate, and the rotating shaft 75f drives the disc-shaped component 75a to rotate through the connecting sleeve 75g, thereby rotating the frame 75b fixed to the disc-shaped component 75a, and the scraping assembly 77 installed on the frame 75b rotates with the frame 75b, and the scraping assembly 77 scrapes the dirt of the light materials attached to the inner wall surface of the lower shell 71a and the upper shell 71b toward the opening 71a4, and these materials are output to the outside of the scraping material separator through the lower cylinder 71a2 and the output port 73. As can be seen from the above, after the light materials are separated by the scraping material separator, the light materials are prevented from clogging the suction assembly.

[0077] Since the support portion 77e is inclined relative to the support plate 77d, when the skeleton 75b is in a stationary state and the supporting component rotates as a whole, the gap between the scraping component 77 and the inner wall surface of the shell 71 can be scraped. Therefore, when the scraping component 77a is worn, the gap between the scraping component 77a and the inner wall surface of the shell 71 becomes larger and the scraping effect is reduced. This problem can be solved by adjusting the scraping component 77.

[0078] Based on the problem that the gap between the scraping component 77a and the inner wall of the shell 71 is adjustable, an adjusting component 78 for adjusting the gap between the scraping component 77 and the inner wall of the shell 71 is provided in this embodiment. The adjusting component 78 is mounted on the rotor component 75, and the adjusting component 78 is fixed to the scraping component 77.

[0079] The adjustment assembly 78 includes a connecting shaft 78a, a sleeve 78b, a connecting arm 78c, an adjustment seat 78d, a screw 78e, and an adjustment nut 78f. One end of the connecting shaft 78a is fixed to the scraping assembly 77, and the other end of the connecting shaft 78a passes through the rotor assembly 75 and is located outside the shell 71; that is, one end of the connecting shaft 78a is connected to the tubular component 77c in the scraping assembly 77, and the other end of the connecting shaft 78a passes through the disc component 75a and is located outside the shell 71. The sleeve 78b is sleeved on the other end of the connecting shaft 78a and fixed to the connecting shaft 78a. The sleeve 78b is a rubber sleeve, and the sleeve 78b and the connecting shaft 78a have an interference fit. The connecting arm 78c is fixed to the sleeve 78b. The sleeve 78b is prism-shaped (regular prism), and the inner hole of the connecting arm 78c is polygonal (quadrilateral). After the connecting arm 78c is sleeved on the sleeve 78b, it is circumferentially fixed.

[0080] The adjustment seat 78d is fixed to the rotor assembly 75; the adjustment seat 78d is fixed on the axial end face of the disc-shaped component 75a in the rotor assembly 75, one end of the screw rod 78e is connected to the connecting arm 78c, the other end of the screw rod 78e passes through the adjustment seat 78d, and the adjustment nut 78f is threadedly connected to the other end of the screw rod 78e.

[0081] The adjustment assembly 78 further includes a pointer 78g, which is fixed to the connecting shaft 78a; an adjustment scale 75d for cooperating with the pointer 78g is provided on the end surface of the rotor assembly 75. The adjustment assembly 78 further includes an axial limit sleeve 78h, which is fixed to the shaft sleeve 78b and forms an axial limit for the connecting arm 78c.

[0082] When it is necessary to adjust the gap between the scraping component 77a and the inner wall of the shell 71, rotate the adjusting nut 78f to make the screw 78e move axially along the adjusting seat 78d, and the adjusting seat 78d drives the connecting arm 78c to rotate, and the connecting arm 78c drives the sleeve 78b to rotate, and the sleeve 78b drives the connecting shaft 78a and the pointer 78g to rotate, and the connecting shaft 78a drives the tubular component 77c to rotate, so that the scraping assembly 77 rotates relative to the shell 71, thereby changing the gap between the scraping component 77a and the inner wall of the shell 71.

[0083] The input end of the air extraction component cooperates with the ventilation hole 74. The air extraction component can be composed of an air extractor and an air hood component. The air hood is connected to the air extractor, and the air hood cooperates with the ventilation hole 74. The negative pressure generated by the air extraction component causes the air flow in the housing 71 to flow to a designated position through the ventilation hole 74. The designated position can be a device such as a dust collector.

[0084] Since the ventilation holes 74 may be blocked or the airflow may be blocked, in order to maintain the air extraction efficiency of the exhaust component, the present embodiment also includes a purge component for reciprocatingly blowing the ventilation holes 74 on the shell 71, and the purge component includes a purge bracket 79, an air jet 80, a reciprocating drive unit, and the air jet 80 is fixed to the purge bracket 79, the air jet 80 is connected to the air supply unit 80a, and the reciprocating drive unit is connected to the purge bracket 79.

[0085] The reciprocating drive unit includes a first driver 81 for outputting torque, a drive arm 82, a connecting rod 83, and a slide rail 84. The drive arm 82 is connected to the torque output end of the first driver 81; the connecting rod 83 is hinged to the drive arm 82, and the connecting rod 83 is also connected to the purge bracket 79; the connecting rod 83 or the purge bracket 79 is slidably matched with the slide rail 84.

[0086] When the ventilation hole 74 needs to be purged, the air supply unit 80a is turned on, and compressed gas is ejected from the jet pipe 80. The first driver 81 outputs torque, and the first driver 81 drives the driving arm 82 to rotate. The driving arm 82 drives the connecting rod 83 to swing back and forth, and the connecting rod 83 drives the purging bracket 79 to move back and forth along the slide rail 84, thereby purging the ventilation hole 74 back and forth and blowing the dirt blocked in the ventilation hole 74 into the shell 71.

[0087] What is disclosed above is only a preferred embodiment of the present application, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the structures of the above embodiments and equivalent changes made according to the claims of this application are still within the scope covered by the application.
