Description

Technical Field

[0001] The utility model relates to the field of waste treatment, in particular to a scraping type material separator. Background Art

[0002] Construction waste refers to the slag, waste concrete, waste bricks and stones, and other waste generated during demolition, construction, renovation, and other construction activities. By composition, construction waste can be divided into slag, concrete blocks, crushed stone, brick and tile fragments, waste mortar, mud, asphalt blocks, waste plastics, scrap metal, waste bamboo and wood, and foam.

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

[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 recycling 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) Waste glass, waste plastic, waste ceramics and other construction waste 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 is classified by weight into heavy waste (heavier waste) and light waste (lighter waste). Therefore, the first sorting step is usually to separate heavy waste from light waste. The equipment commonly used to separate heavy waste from light waste is air separation equipment, such as the air separator disclosed in CN114522881A. The working principle of this air separator is as follows: construction waste is fed into the air separation equipment through the input port, 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 combined action of the jet assembly and the separation drum. The ultra-light waste is carried away by the airflow generated by the vacuum pump.

[0014] Light waste often contains large amounts of dust, lightweight materials (plastics, foam), and small particles. When these materials pass through the vacuum pump, the lightweight materials can easily cause blockage. Although some air separation equipment currently has filters installed in the settling chamber, the filters are composed of multiple chains. However, these chains can only block lightweight materials and cannot filter small particles, which can still cause blockage of the vacuum pump. In addition, lightweight materials can easily become entangled in the chains, requiring regular cleaning. Utility Model Content

[0015] The utility model provides a scraping type material separator, which can prevent light materials from clogging an air extraction component.

[0016] The technical solutions to the above technical problems are as follows:

[0017] Scraper-type material separator, including:

[0018] A shell, wherein an input port, an output port, and a ventilation hole are respectively provided on the shell;

[0019] a rotor assembly, the rotor assembly being rotationally engaged with the housing;

[0020] The rotating support assembly is fixed to the housing, and the rotor assembly passes through the housing and is connected to the rotating support assembly;

[0021] The scraping assembly cooperates with the rotor assembly, and the scraping assembly is located in the shell and fits with the inner wall surface of the shell;

[0022] An air extraction component, wherein the input end of the air extraction component cooperates with the ventilation hole.

[0023] In the present invention, the working process of the scraper-type material separator is as follows: light garbage enters the shell through the input port, and the negative pressure generated by the exhaust component causes the airflow and most of the fine objects such as dust to pass through the vents. Light materials (plastics, foams, etc.) that cannot pass through the air vents will adhere to the inner wall surfaces of the lower shell and the upper shell, and dust-like materials that do not pass through the vents will also adhere to the inner wall surfaces of the lower shell and the upper shell. The reduction motor is started to work, and the output torque of the reduction motor drives the rotating shaft to rotate. The rotating shaft drives the disc-shaped component to rotate through the connecting sleeve, thereby rotating the frame 1 fixed to the disc-shaped component. The scraper component installed on the frame rotates with the frame, and the scraper component scrapes the dirt of the light materials attached to the inner wall surfaces of the lower shell and the upper shell to the opening. These materials are output to the outside of the scraper-type material separator through the lower cylinder and the output port. As can be seen from the above, after the light materials are separated by the scraper-type material separator, the light materials are prevented from clogging the exhaust component.

DETAILED DESCRIPTION

[0035] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0036] like Figures 1 to 9 As shown, the scraper-type material separator of the present invention includes a shell 11, a rotor assembly 15, a rotating support assembly 16, a scraper assembly 17, and an exhaust assembly (not shown in the figure). The various parts of the scraper-type material separator and the relationship between them are described in detail below.

[0037] The housing 11 is provided with an input port 12, an output port 13, and a ventilation hole 14. The housing 11 comprises a lower housing 11a, an upper housing 11b, a lower support 11c, and an end plate 11d. When the upper housing 11b is connected to one end of the lower housing 11a, the input port 12 is formed between the two housings 11b. The output port 13 is located at the other end of the lower housing 11a. The ventilation hole 14 is provided in the upper housing 11b. The ventilation holes 14 are formed by punching holes in the upper housing 11b. The diameter of the ventilation holes 14 is preferably 4 mm. The upper housing 11b is curved, and the ventilation holes 14 are distributed uniformly across the entire curved surface of the upper housing 11b. Only a portion of the ventilation holes is shown in the figure.

[0038] The lower support 11c is connected to the lower housing 11a. This ring-shaped support 11c is fixed to another supporting structure, such as the frame, and serves as the primary support for the entire scraper-type material separator. The end plates 11d mate with the axial end faces of the lower and upper housings 11a and 11b, respectively, and are secured thereto. The end plates 11d are provided with clearance holes 71e for mating with the rotor assembly 15. The rotational support assembly 16 is secured to the end plates 11d.

[0039] The lower shell 11a includes a lower arc seat 11a1, a lower cylinder 11a2, and a side support plate 11a3. The arc of the lower arc seat 11a1 is preferably 180°, that is, the lower arc seat 11a1 is semicircular. The lower arc seat 11a1 is fixed to the lower cylinder 11a2. The lower cylinder 11a2 is composed of a conical cylinder and a cylindrical cylinder. The conical cylinder is located between the lower arc seat 11a1 and the cylindrical cylinder. The volume of the conical cylinder is smaller than that of the cylindrical cylinder, making it easy to install in a small space. The side support plate 11a3 is fixed to the lower arc seat 11a1. The side support plate 11a3 can be fixed to other supporting parts, such as the frame, to better support the lower shell 11a. The lower arc seat 11a1 is provided with an opening 11a4, which is connected to the lower cylinder 11a2. The lower arc seat 11a1 is fixed to the upper shell 11b.

[0040] The rotor assembly 15 is rotatably engaged with the housing 11. The rotor assembly 15 includes a disc-shaped component 15a, a skeleton 15b, and a drive unit. The disc-shaped component 15a is rotatably engaged with the housing 11. The disc-shaped component 15a is clearance-matched with the clearance hole 71e in the housing 11, so that the disc-shaped component 15a can rotate relative to the housing 11. The two ends of the skeleton 15b are respectively fixed to the disc-shaped component 15a. The skeleton 15b is a cylindrical component. The skeleton 15b can be a hollow cylinder or a hollow prism. In this embodiment, the skeleton 15b preferably adopts a hollow hexagonal prism.

[0041] An assembly groove 15c is provided on the circumferential surface of the skeleton 15b. One end of the scraping assembly 17 is engaged with the assembly groove 15c. The driving unit is fixed to the disc-shaped component 15a and / or the skeleton 15b.

[0042] The driving unit includes a reduction motor 15e, a rotating shaft 15f, and a connecting sleeve 15g. The reduction motor 15e is fixed to the rotating shaft 15f. The rotating shaft 15f passes through the disc-shaped component 15a and the skeleton 15b. The connecting sleeve 15g is sleeved on the rotating shaft 15f. The connecting sleeve 15g is an open sleeve. The open sleeve is locked on the rotating shaft 15f with bolts, so that the connecting sleeve 15g and the rotating shaft 15f are fastened as one. The connecting sleeve 15g is also fastened to the disc-shaped component 15a by bolts. Therefore, when the reduction motor 15e outputs torque, the rotating shaft 15f, the disc-shaped component 15a and the skeleton 15b are driven to rotate.

[0043] The rotor assembly 15 further includes a limiting plate 15 h , which is fixed to the disc-shaped component 15 a , and the limiting plate 15 h forms an axial limit for the scraping assembly 17 .

[0044] Rotational support assembly 16 is fixed to housing 11, and rotor assembly 15 passes through housing 11 and is connected to rotational support assembly 16. Rotational support assembly 16 comprises a support frame and bearings, which are mounted on the support frame. The ends of the support frame are fixed to end plates 11d, respectively, leaving a gap between the support frame and disc-shaped member 15a. The end of the rotating shaft 15f is connected to the bearing in rotational support assembly 16.

[0045] The scraper assembly 17 cooperates with the rotor assembly 15. It is located within the housing 11 and conforms to the inner wall of the housing 11. The scraper assembly 17 comprises a scraper component 17a that conforms to the inner wall of the housing 11, a support component, and an elastic colloid 17b that conforms to the rotor assembly 15. The scraper component 17a is a scraper bar and / or a stainless steel brush strip. In this embodiment, the scraper component 17a is composed of PV scraper bars and stainless steel brush strips, which are arranged alternately along the circumference. The PV scraper bars help scrape dirt and light debris toward the opening 11a4, while the stainless steel brush strips help clean the ventilation holes 14, reducing the chance of clogging. The elastic colloid 17b mates with the assembly slot 15c.

[0046] One end of the support component is fixed to the scraping component 17a. The elastic colloid 17b is provided with a groove, and the other end of the support component mates with the groove of the elastic colloid 17b. The support component includes a tubular component 17c, a support plate 17d, a support portion 17e, and a protrusion 17f. One end of the support plate 17d is fixed to the tubular component 17c, and the support portion 17e is fixed to the other end of the support plate 17d. The support portion 17e and the support plate 17d form an angle between them, and the support portion 17e is inclined relative to the support plate 17d. The scraping component 17a is fixed to the support portion 17e, and one end of the protrusion 17f is fixed to the tubular component 17c. The other end of the protrusion 17f mates with the groove of the elastic colloid 17b.

[0047] The working process of the scraper type material separator is as follows: light garbage enters the shell 11 through the input port 12, and the negative pressure generated by the exhaust component causes the airflow and most of the fine objects such as dust to pass through the vents. Light materials (plastics, foam, etc.) that cannot pass through the air vents will adhere to the inner wall surfaces of the lower shell 11a and the upper shell 11b, and dust-like materials that have not passed through the ventilation holes 14 will also adhere to the inner wall surfaces of the lower shell 11a and the upper shell 11b. The reduction motor 15e is started to work, and the reduction motor 15 The output torque of the motor e rotates the rotating shaft 15f, which in turn rotates the disc-shaped component 15a via the connecting sleeve 15g, thereby rotating the frame 15b fixed to the disc-shaped component 15a. As the frame 15b rotates, the scraper assembly 17 mounted on the frame 15b scrapes the light material dirt adhering to the inner walls of the lower shell 11a and the upper shell 11b toward the opening 11a4. This dirt is then discharged to the outside of the scraper-type material separator through the lower cylinder 11a2 and the output port 13. As can be seen from the above, after the light material is separated by the scraper-type material separator, the light material prevents the air extraction component from being blocked by the light material.

[0048] Since the support portion 17e is inclined relative to the support plate 17d, when the skeleton 15b is in a stationary state and the supporting component rotates as a whole, the gap between the scraping component 17 and the inner wall surface of the shell 11 can be scraped. Therefore, when the scraping component 17a is worn, the gap between the scraping component 17a and the inner wall surface of the shell 11 becomes larger and the scraping effect is reduced. This problem can be solved by adjusting the scraping component 17.

[0049] Based on the problem that the gap between the scraping component 17a and the inner wall of the shell 11 can be adjusted, an adjustment component 18 is provided in this embodiment for adjusting the gap between the scraping component 17 and the inner wall of the shell 11. The adjustment component 18 is installed on the rotor component 15, and the adjustment component 18 is fixed to the scraping component 17.

[0050] The adjusting assembly 18 includes a connecting shaft 18a, a sleeve 18b, a connecting arm 18c, an adjusting seat 18d, a screw 18e, and an adjusting nut 18f. One end of the connecting shaft 18a is fixed to the scraping assembly 17, and the other end of the connecting shaft 18a passes through the rotor assembly 15 and is located outside the shell 11; that is: one end of the connecting shaft 18a is connected to the tubular component 17c in the scraping assembly 17, and the other end of the connecting shaft 18a passes through the disc-shaped component 15a and is located outside the shell 11. The sleeve 18b is sleeved on the other end of the connecting shaft 18a and fixed to the connecting shaft 18a. The sleeve 18b is a rubber sleeve, and the sleeve 18b and the connecting shaft 18a have an interference fit. The connecting arm 18c is fixed to the sleeve 18b. The sleeve 18b is prismatic (regular prism), and the inner hole of the connecting arm 18c is polygonal (quadrilateral). After the connecting arm 18c is sleeved on the sleeve 18b, it is circumferentially fixed.

[0051] The adjusting seat 18d is fixed to the rotor assembly 15; the adjusting seat 18d is fixed on the axial end face of the disc-shaped component 15a in the rotor assembly 15, one end of the screw 18e is connected to the connecting arm 18c, the other end of the screw 18e passes through the adjusting seat 18d, and the adjusting nut 18f is threadedly connected to the other end of the screw 18e.

[0052] The adjustment assembly 18 also includes a pointer 18g, which is fixed to the connecting shaft 18a. An adjustment scale 15d is provided on the end surface of the rotor assembly 15 for cooperating with the pointer 18g. The adjustment assembly 18 also includes an axial limit sleeve 78h, which is fixed to the shaft sleeve 18b and provides axial restraint for the connecting arm 18c.

[0053] When it is necessary to adjust the gap between the scraping component 17a and the inner wall of the shell 11, rotate the adjusting nut 18f to make the screw 18e move axially along the adjusting seat 18d, and the adjusting seat 18d drives the connecting arm 18c to rotate, and the connecting arm 18c drives the sleeve 18b to rotate, and the sleeve 18b drives the connecting shaft 18a and the pointer 18g to rotate, and the connecting shaft 18a drives the tubular component 17c to rotate, so that the scraping assembly 17 rotates relative to the shell 11, thereby changing the gap between the scraping component 17a and the inner wall of the shell 11.

[0054] The input end of the air extraction assembly cooperates with the ventilation hole 14. The air extraction assembly can be composed of an air extractor and an air hood assembly, the air hood being connected to the air extractor and cooperating with the ventilation hole 14. The negative pressure generated by the air extraction assembly causes the air flow in the housing 11 to flow through the ventilation hole 14 to a designated location, which can be a device such as a dust collector.

[0055] Since the ventilation holes 14 may be blocked or the airflow may be poor, in order to maintain the exhaust efficiency of the exhaust assembly, this embodiment also includes a purge assembly for reciprocatingly blowing the ventilation holes 14 on the shell 11. The purge assembly includes a purge bracket 19, an air jet 20, a reciprocating drive unit, and the air jet 20 is fixed to the purge bracket 19. The air jet 20 is connected to the air supply unit 20a, and the reciprocating drive unit is connected to the purge bracket 19.

[0056] The reciprocating drive unit includes a first driver 21 for outputting torque, a drive arm 22, a connecting rod 23, and a slide rail 24. The drive arm 22 is connected to the torque output end of the first driver 21; the connecting rod 23 is hinged to the drive arm 22, and the connecting rod 23 is also connected to the purge bracket 19; the connecting rod 23 or the purge bracket 19 is slidably matched with the slide rail 24.

[0057] When the ventilation hole 14 needs to be purged, the air supply unit 20a is turned on, and compressed gas is ejected from the injection pipe 20. The first driver 21 outputs torque, and the first driver 21 drives the driving arm 22 to rotate. The driving arm 22 drives the connecting rod 23 to swing back and forth, and the connecting rod 23 drives the purging bracket 19 to move back and forth along the slide rail 24, thereby purging the ventilation hole 14 back and forth, and blowing the dirt blocked in the ventilation hole 14 into the shell 11.

[0058] The above disclosure is only a preferred embodiment of the present application, and it is certainly not intended to limit the scope of rights of the present invention. A person skilled in the art can understand that all or part of the structures of the above embodiment can be implemented and equivalent changes made in accordance with the claims of the present application are still within the scope of the application.
