Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a waste treatment device for shantytown renovation. Background Art

[0002] Building waste treatment is a way to reuse solid waste as renewable resources. Building waste is solid waste generated during the construction, reconstruction, expansion or demolition of buildings. According to the different sources of building waste, it can be divided into construction construction waste and demolition construction waste. As the name implies, construction construction waste is solid waste generated during new construction, reconstruction or expansion projects, while demolition construction waste is construction waste generated during the demolition of buildings.

[0003] In the shantytown renovation project, since most of the housing buildings in the shantytown are old buildings, after demolition, they mainly include waste bricks, tiles, wood, etc. For wood that can be sorted and has not been significantly damaged, it can be directly reused for rebuilding buildings. Severely damaged wooden components can be used as raw materials for wood-based recycled boards or for papermaking, etc. However, waste bricks and tiles need to be reprocessed before they can be reused. Content of the Utility Model

[0004] Aiming at the deficiencies and problems in the prior art, the utility model aims to provide a waste treatment device for shantytown renovation.

[0005] The utility model is realized through the following technical solutions:

[0006] A waste treatment device for shantytown renovation includes a vertical screw conveyor, a crushing pair-roller device, a pulverizing pair-roller device and a vibrating sieve device arranged in sequence from top to bottom. The lower end of the vertical screw conveyor is the waste inlet and the upper end is the waste outlet. A raw material hopper is arranged at the waste inlet and a discharge pipe is installed at the waste outlet. An inclined feeding channel is arranged at the feeding port of the crushing pair-roller device, and the feeding channel is hermetically connected to the discharge pipe;

[0007] Both the crushing pair-roller device and the pulverizing pair-roller device adopt pair-roller crushers; wedge-shaped convex bodies are arranged on the surfaces of the oppositely rotating roller wheels of the crushing pair-roller device; the oppositely rotating roller wheels of the pulverizing pair-roller device are smooth-surfaced round rollers; and the distance between the two roller wheels of the crushing pair-roller device is greater than the distance between the two roller wheels of the pulverizing pair-roller device;

[0008] The discharge port of the crushing pair-roller device is connected to the feeding port of the pulverizing pair-roller device through a first discharger, and the discharge port of the pulverizing pair-roller device is connected to the feeding port of the vibrating sieve device through a second discharger;

[0009] The vibrating screening device includes a linear vibrating screen, a connecting hopper arranged at the feeding port of the linear vibrating screen, an enclosure arranged outside the screen mesh of the linear vibrating screen, and a discharging hopper communicated with the fine material outlet of the linear vibrating screen. The connecting hopper is hermetically communicated with the outlet of the second discharger.

[0010] Further, both the first discharger and the second discharger adopt star dischargers.

[0011] Further, protective cylinders are arranged outside both the crushing pair roll device and the pulverizing pair roll device to prevent dust from spreading during the treatment of construction waste, thus avoiding environmental pollution.

[0012] Further, since the crushed materials processed by the pulverizing pair roll device are smaller in particle size and closer to a powder structure, it is very easy for materials to adhere to the surface of the roll wheels. Therefore, an upper baffle is arranged above the roll wheels of the pulverizing pair roll device, and a lower scraper is arranged below the roll wheels. Both the lower scraper and the upper baffle are in contact with the surface of the roll wheels.

[0013] Further, the coarse material outlet of the linear vibrating screen is communicated with the raw material inlet hopper.

[0014] Further, the utility model further includes a frame, which provides support for the crushing pair roll device, the first discharger, the pulverizing pair roll device, the second discharger, and the vibrating screening device.

[0015] Further, a ladder can also be installed on the frame.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. In the utility model, a vertical screw conveyor is used to convey waste materials such as bricks, stones, etc. generated during the shantytown renovation to the upper part, and then the waste materials are successively processed by the crushing pair roll device to obtain granular waste materials, processed by the pulverizing pair roll device to obtain powdery waste materials, and screened by the vibrating screening device to separate construction waste materials of different particle sizes.

[0018] 2. The utility model uses a linear vibrating screen as the main body of the vibrating screening device, and uses the vibration of the vibration motor as the power source of vibration, so that the construction waste materials are thrown up on the screen mesh and move forward in a straight line at the same time. The waste material particles uniformly enter the connecting hopper of the linear vibrating screen from the second discharger, and the oversize materials and undersize materials generated by the screen mesh are discharged from their respective outlets; it has the advantages of low energy consumption, high output, simple structure, easy maintenance, fully enclosed structure, no dust dispersion, and automatic discharging.

[0019] 3. The crushing pair roll device and the pulverizing pair roll device of the utility model perform secondary treatment on construction waste materials such as bricks and stones described in the shantytown renovation, easily changing the waste materials from large blocks or flakes into small particles, and then into tiny particles or powders, and recycling the fine materials that meet the recycling requirements.

[0020] 4. The coarse material outlet of the linear vibrating screen of the utility model is connected with the raw material inlet hopper of the vertical screw conveyor, so that the coarse material is transported to the crushing roller device together with the original construction waste through the vertical screw conveyor, and then is crushed again through the crushing roller device and the pulverizing roller device for secondary crushing.

[0021] 5. The utility model utilizes a star-shaped discharger as a transfer feeding device, the upper part of which receives the construction waste discharged by the crushing roller device or the pulverizing roller device, and relies on the rotating impeller to transport the construction waste and also bear the role of sealing, which can effectively prevent dust from flying around during the processing process.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "right", "left", etc. are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0029] In order to illustrate the technical solutions described in the present utility model, the following will be described through specific embodiments.

[0030] As Figures 1 to 3 shown, a waste treatment device for shantytown renovation includes a vertical screw conveyor 2, a crushing roll device 5, a pulverizing roll device 8, and a vibrating sieve device 10 arranged in sequence from top to bottom. The lower end of the vertical screw conveyor 2 is the waste inlet, and the upper end is the waste outlet. A raw material hopper 1 is arranged at the waste inlet, and a discharge pipe 3 is installed at the waste outlet. An inclined feeding channel 4 is provided at the feeding port of the crushing roll device 5, and the feeding channel 4 is hermetically connected to the discharge pipe 3. The spiral blades welded on the rotating shaft of the vertical screw conveyor 2 use the rotating spiral blades to push the conveyed materials along the fixed casing for upward conveying. In the present utility model, the vertical screw conveyor 2 is used to convey the waste such as bricks, stones, etc. generated in shantytown renovation to the upper part, and then successively pass through the crushing roll device 5 to obtain granular waste, pass through the pulverizing roll device 8 to obtain powdery waste, and pass through the vibrating sieve device 10 to screen and separate construction waste with different particle sizes.

[0031] Both the crushing roll device 5 and the pulverizing roll device 8 adopt roll-type crushers. Mainly, solid waste falls between the two roll wheels through the feeding port for extrusion and crushing, and the crushed materials fall naturally. The difference between them is that wedge-shaped convex bodies are provided on the surfaces of the oppositely rotating roll wheels of the crushing roll device 5; the oppositely rotating roll wheels of the pulverizing roll device 8 are smooth-surfaced round rolls; and the distance between the two roll wheels of the crushing roll device 5 is greater than the distance between the two roll wheels of the pulverizing roll device 8. Since the bricks, stones, etc. generated in shantytown renovation are all solid wastes with moderate hardness, the crushing roll device 5 and the pulverizing roll device 8 can relatively easily change the waste from large pieces or flakes into small particles, and then into tiny particles or powders.

[0032] The discharge port of the crushing roller device 5 and the feed port of the pulverizing roller device 8 are connected by the first discharger 7, and the discharge port of the pulverizing roller device 8 and the feed port of the vibrating screening device 10 are connected by the second discharger 9. Both the first discharger 7 and the second discharger 9 are star-shaped dischargers, and the structure of the star-shaped discharger is composed of a rotor impeller with several blades, a shell, a seal, a reducer, a motor, etc. The upper part of the star-shaped discharger receives the construction waste discharged by the crushing roller device 5 or the pulverizing roller device 8, and plays the role of conveying the construction waste by the rotating impeller, and also plays the role of sealing, which can effectively prevent the dust from flying around during the treatment process.

[0033] Protective tubes are provided outside the crushing roller device 5 and the pulverizing roller device 8 to prevent dust from overflowing and affecting the environment and causing pollution when processing construction waste.

[0034] Since the crushed materials processed by the crushing roller device 8 are smaller and close to the powder structure, the roller surface is very easy to adhere to the materials, so an upper baffle 13 is set above the roller of the crushing roller device 8, and a lower scraper 12 is set below the roller. The lower scraper 12 and the upper baffle 13 are both against the roller surface. The lower scraper 12 and the upper baffle 13 form a certain scraping action on the roller surface to keep the roller surface clean, and the upper baffle 13 also prevents the waste from splashing and guides the waste to fall into the feeding port.

[0035] The vibration screening device 10 comprises a linear vibration screen 1003, a connecting hopper 1001 arranged on the feeding port of the linear vibration screen 1003, a sealing cover 1002 arranged outside the screen of the linear vibration screen 1003, and a discharge hopper 1004 connected to the fine material outlet of the linear vibration screen 1003. The connecting hopper 1001 is sealed and connected to the outlet of the second discharger 9. The linear vibration screen 1003 uses vibration motor excitation as a vibration power source to make the construction waste be thrown up on the screen and move forward linearly at the same time. The waste particles enter the connecting hopper 1001 of the linear vibration screen 1003 evenly from the second discharger 9, and the screened material and the screened material generated by the screen are discharged from their respective outlets respectively; it has low energy consumption, high output, simple structure, easy maintenance, fully enclosed structure, no dust spillage, and automatic discharge.

[0036] In a specific implementation, the construction waste in the shantytowns that has been processed by the crushing roller device 5 and the pulverizing roller device 8 is fine material that meets the recycling requirements and can be discharged and recycled through the discharge hopper 1004, while the waste that does not meet the recycling requirements is coarse material that can be returned to the crushing roller device 5 for further processing. The coarse material outlet of the linear vibrating screen 1003 is connected to the raw material inlet hopper 1, so that the coarse material and the original construction waste are transported to the crushing roller device 5 through the vertical screw conveyor 2, and then processed by the crushing roller device 5 and the pulverizing roller device 8 for secondary crushing.

[0037] In some preferred embodiments, the utility model further includes a frame 6, and the frame 6 provides support for the crushing roller device 5, the first discharger 7, the pulverizing roller device 8, the second discharger 9, the vibrating sieve device 10, etc., so as to form a more smooth overall device.

[0038] A ladder 11 can also be installed on the frame 6 to facilitate the maintenance of each part unit by the staff.

[0039] The above only expresses the preferred embodiments of the utility model, and its description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several deformations, improvements and substitutions can be made, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
