Description

Construction Waste Recycling Equipment {APPARATUS FOR REPRODUCING CONSTRUCTION WASTES}

The present invention relates to a construction waste recycling apparatus, and more particularly, to a construction waste recycling apparatus in which only raw stones that need to be crushed are supplied to the crusher in the process of regenerating construction waste mixed with raw stones (concrete lumps), earth and sand, and the like. It is about.

According to the so-called development priority policy and high-growth policy promotion, it has been a reality that the adverse environmental problem in Korea has been somewhat out of consideration.

However, as a result of this growth-oriented policy, the growth of various wastes and pollutants in the by-products has reached an urgent point which can no longer be delayed.

In particular, the construction industry wastes of various construction and civil works show a sharp increase, mainly due to the redevelopment, activation of reconstruction, and dismantling of structures, which are actively progressed due to deterioration and deterioration of urban and local buildings. do.

In general, construction waste refers to soil, sand, gravel, earth or soil mixed with rubbish and waste materials, and concrete lumps, waste wood, asphalt concrete lumps, and construction sludge. One of the main characteristics is that most of the construction wastes are composed of inorganic materials, which are harmless to the human body, and that various kinds of wastes are discharged in a mixed state, and the treatment is complicated and difficult. It is said to provide the cause of indifference between the government and industry regarding waste disposal.

Such indifference entailed a waste of valuable resources and caused deterioration of the quality of the recycled aggregate, which was being made, and most of the utilization of the recycled aggregate was used as soil substitute, soil cover, and landfill.

Therefore, by realizing the recycling through the management of such wastes, it is necessary to actively minimize the environmental pollution, replace the scarce resources, and reduce the cost of the construction industry base.

To this end, the Law on the Promotion of Saving and Recycling of Resources has recently been enacted in Korea, and the recycling of construction waste has become mandatory, and various production facilities for recycling have been produced and applied to various industrial sites.

As described above, in accordance with the mandatory recycling of construction wastes, various devices have been proposed to handle the partial or partial disposal of waste from waste treatment to regeneration.

Construction waste recycling technology according to the prior art, the hopper to which the construction waste is usually input, the feeder for supplying the construction waste put into the hopper in an appropriate amount, one or more shredding means for crushing the construction waste supplied through the feeder, reinforcement in the construction waste It comprises a magnet means for sorting, washing means for washing construction waste, a screen for sorting construction waste by particle size, and a conveyor for transporting construction waste.

Construction waste recycling technology according to the prior art is mainly used the method of primary crushing → screening → secondary crushing → screening. This work method can not improve the quality of recycled aggregates in domestic construction waste generation conditions, and the produced recycled aggregates cannot be used at each construction site, so most of them cannot be used for cover or simple landfill. In particular, most of domestic construction waste is mixed waste, and the existing technology has a limitation in sorting out waste, and most of it is buried in landfills.

Specifically, the construction waste is currently generated in the form of mixed waste rather than simple construction waste due to the lack of environmental awareness and the lack of pre-separation work during the dismantling work. In other words, the construction waste supplied to the regeneration facility is a state in which raw materials (agglomerates), earth and sand, and foreign substances (waste vinyl, waste wood, waste styrofoam, waste clothing, etc.) are mixed, and thus, primary materials are mixed in various states. Crushing → Selection → Secondary crushing → Selection process, but the actual crushing object is a gemstone of a certain size or more, but the selected and selected products after crushing in the state of mixed raw materials, earth and sand Because of this mixed state, the quality of aggregates is poor.

In addition, the technology of the conventional construction waste site is selected before the construction waste is put into the primary crusher, so that the waste must be put on the floor (ground) with equipment and manually collected by manpower and put back into the equipment. The work is cumbersome and inefficient.

In addition, when first crushing, foreign matters such as wood are finely crushed like raw stone and mixed together with aggregates, so that foreign matters such as wood chips are mixed together with aggregates when screening aggregates. .

In addition, the crushed crushed material mixed with raw materials, earth and sand, and the foreign matter is selected by the blowing force, at this time, because the crushed fine aggregate is blown with the foreign matter to weaken the strength of the wind (the fine aggregate strength is not affected by the wind) Have no choice but to. Therefore, the selected aggregate, earth and sand is not pure, but mixed with each other, there is a disadvantage that the quality of the product is degraded and undergo a re-selection process.

In addition, such prior art may cause equipment failure as well as product quality. Since crushers such as jaw crushers are designed to crush ore, not only waste but other wastes are crushed, and the crushing efficiency is reduced.

The present invention is to solve the above-mentioned problems, prior to crushing the waste of the mixed state of the raw stone, earth and sand, and prior to the crushing only the crushing object to supply to the crusher construction waste recycling apparatus to crush only the raw stone The purpose is to provide.

Construction waste recycling apparatus according to the present invention provided to achieve the above object, the raw material, the earth and sand, and supplies only the raw materials that need to be shredded in the waste of the mixed state, the soil and the foreign matter before screening process Characterized in that configured to sort by the blowing force.

The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings. Prior to this, the terms or words used in the present specification and claims are defined in the technical spirit of the present invention on the basis of the principle that the inventor can appropriately define the concept of the term in order to explain his invention in the best way. It must be interpreted to mean meanings and concepts.

As shown in Figures 1 to 3, the construction waste recycling apparatus according to the present invention, the vibration feeder 100 to receive the waste is supplied in an appropriate amount and a predetermined particle size of the construction waste supplied through the vibration feeder 100 Soil sorting screen (200) for sorting the following earth and sand, and installed on one side of the soil screening screen (200), light foreign matter in the construction waste passing through the soil screening screen (200) by blowing power (waste vinyl, waste wood, Blower 300 (shown in FIG. 3) for sorting waste clothing, waste styrofoam, dust, etc., and the raw materials (concrete lumps) (soil and foreign matter from the construction wastes) that passed through the screening screen (200) It is configured to include a crusher (400) to receive and crush the remaining concrete mass).

That is, the earth and sand sorting screen 200 and the blower 300 separates the waste by different methods, but is separated from each other by removing the soil and foreign substances from the waste supplied from the vibrating feeder 100 to the raw material in the crusher 400 It can only be supplied.

The vibration feeder 100 is disposed at the bottom of the box-shaped hopper 110, the upper side and one side of which is open so that the waste can be stably supplied, dropping waste stuck to each other while shaking by the vibration motor 120 and stagnant. Supply the proper amount of waste without any phenomenon.

The earth and sand screening screen 200 is provided with a plurality of screening holes 210 of a predetermined diameter (it does not limit the diameter because it may vary depending on the size of the soil to be selected) and the vibration feeder 100 while shaking through the vibration motor 220 The sewage of the particle size less than the selection hole 210 is discharged from the waste supplied to the lower part. The earth and sand sorting screen 200 is inclined downward toward the crusher 400 to facilitate the movement of the waste.

The earth and sand sorting screen 200 for achieving the above object may be in the form of a box in which a plurality of vertical walls 211 are arranged in a row with the sorting holes 210 therebetween. At this time, the waste is contained in the upper portion of the partition wall 211 (the inlet side of the selection hole 210) to block the selection hole 210, so to minimize this, the upper portion of the partition wall 211 is formed in a curved shape do. A conveyor 230 may be disposed at a lower portion of the earth and sand sorting screen 200 to transport the earth and sand having passed through the sorting hole 210 of the earth and sand sorting screen 200 to a predetermined place.

When the foreign matter is discharged to the outside of the earth and sand sorting screen 200 by the blowing force of the blower 300, some soil and rubble may be discharged together with the foreign matter, and the raw stones discharged together with the foreign matter are accumulated on the sorting site. To be contaminated and removed through a separate operation, in order to minimize such unnecessary work, the other side of the earth screening screen 200 (opposite side of the blower 300) is formed with a raw stone discharge blocking plate 240. The raw stone discharge blocking plate 240 is disposed to be inclined upward toward the free end so that the raw stone to be discharged along the surface of the earth and sand sorting screen 200 by the blowing force is not discharged to the outside by inclining.

As shown in FIG. 3, the blower 300 has the tuyere 310 disposed on one side of the earth and sand sorting screen 200, and blows the wind from one side of the earth and sand sorting screen 200 to the other side. Light foreign substances in the waste passing through are removed to the outside of the sediment sorting screen (200) (the opposite side of the tuyere 310 around the soil sorting screen 200).

At this time, when the blowing force of the blower 300 extends to the entire area of the screening screen 200, the soil may be removed together with the foreign matter by the blowing power, so that the soil is screened through the screening screen 200 The blower 310 of the blower 300 is installed on the discharge side of the screening screen 200 (for example, the discharging end from the center of the screening screen 200) so that the wind passes only a part of the screening screen 200. Do it. That is, the soil screening screen 200 is divided into the soil screening area (S1) and the foreign matter screening area (S2) by the blowing, because the soil is selected through the soil screening area (S1), the foreign matter screening area ( By supplying a strong blowing force to the waste (soil is screened and mixed with ore and foreign matter) through S2), it is possible to effectively screen the foreign matter.

The foreign matter storage unit 500 may be provided on the opposite side of the tuyere sorting screen 200 with the foreign matter removed to the outside of the earth and sand sorting screen 200 collected by the blowing force of the blower 300. have. Since the foreign matters selected by the blowing force are mixed with waste vinyl, waste wood, and waste clothing, they should be sorted again, and the partition plate 510 is disposed inside the foreign matter storage unit 500 so as to naturally sort them by a weight difference. ) Is further formed. That is, relatively light waste vinyl, waste clothing, etc. among the foreign matters are collected in the upper part of the partition plate 510, and relatively heavy waste wood is collected in the lower part of the partition plate 510.

The crusher 400 may be a known jaw crusher, and receives and grinds the raw material from which the soil and the foreign matter have been removed by the earth and sand sorting screen 200 and the blower 300 while passing through the earth and sand sorting screen 200. That is, even if the mixed waste (mixed stones, earth and sand, foreign matter mixed) is put into the vibration feeder 100, the shredder 400 is supplied and crushed only the raw material from which the soil and the foreign matter is removed.

The lower portion (discharge port) of the crusher 400 is equipped with a conveyor 410 for transferring the aggregate crushed by the crusher 400.

Reference numeral 1 in the drawings is a frame for integrally installing the vibration feeder 100, the earth and sand screening screen 200, the blower 300 and the shredder 400.

Construction waste recycling method according to the present invention is as follows.

(S10) Construction waste feeding. When the construction wastes mixed with raw materials (concrete lumps), soil, and foreign substances are put into the hopper 110 of the vibrating feeder 100, the vibrating feeder 100 vibrates through the vibrating motor 120 while transferring the input wastes. Drop the attached waste.

(S20) sediment, foreign matter, stone selection. Waste falls to the earth and sand sorting screen 200 by an appropriate amount without the congestion phenomenon through the vibration feeder 100, and the soil and the foreign matter is removed while passing through the earth and sand sorting screen 200 is vibrated by the vibration motor 220. Specifically, as described above, the waste of the mixed state, such as raw materials, earth and sand, foreign matter is injected into the soil screening area (S1) of the soil screening screen 200, than the sorting hole 210 of the waste Soil having a small particle size falls down through the sorting hole 210 and is transported on the conveyor 230. The earth and sand selection area (S1) is not affected by the blower 300, so the soil is selected only by the particle size and the size of the sorting hole.

Wastes from which earth and sand are sorted (a state in which raw materials and foreign substances are mixed) are subjected to the foreign matter selection area (S2). In this process, the wind from the blower 300 is discharged to the tuyere 310, so that the wind blowing in one direction (crossing the conveying path of the waste) from one side of the sediment screening screen (200) to the earth and sand screening screen (200) The foreign matter (waste vinyl, waste wood, waste clothing, waste styrofoam, dust, etc.) that has a specific gravity greater than the blowing force among the wastes transported along the upper surface of the waste) is affected by the wind and moves to the outside of the sediment sorting screen 200 with the wind. Discharged. At this time, some gemstones may be affected by the wind, but the gemstones do not cross the inclination of the earth and sand discharge prevention plate 240 and again flow down to the earth and sand screening screen (200).

The foreign matter removed to the outside of the earth and sand screening screen 200 by the blowing force of the blower 300 is collected in the foreign matter storage unit 500 on the opposite side of the blower 310, light waste vinyl, waste clothing, waste styrofoam, etc. Gathered in the upper plate 510, heavy waste wood, etc. are collected in the lower portion of the partition plate 510 can be sorted by foreign matter without a separate process.

That is, the waste put into the vibrating feeder 100 is mixed with raw materials, earth and sand, but the soil and the foreign matter that is not required to be shredded before being supplied to the shredder 400 are selected to pass the shredding to the shredder 400. Only raw stones are supplied.

(S30) Broken stones (concrete lumps). The crusher 400 crushes the gemstones falling from the discharge end of the soil separation screen 200. Aggregate crushed by the crusher 400 is transferred along the conveyor 410.

As described above, according to the construction waste recycling apparatus according to the present invention, only raw ore which has to undergo crushing among the raw materials (concrete agglomerates), earth and sand, and mixed with the foreign matter is supplied to the crusher, and the soil and the foreign matter are removed before the crushing process. As it is sorted by type, pure soil and aggregate are produced, thus improving the quality of the product. Particularly, when the waste is sorted by the blowing force, the waste may be selected because all the foreign matters may be applied because the soil is already selected and only the raw materials and the foreign matter are mixed.

In addition, the present invention is a breakthrough technology that is superior in technology than the technology of simply shredding and sorting construction waste by the process of sorting foreign matter with strong wind immediately before the first shredding, and it is possible to input a large amount of construction waste, thus wasting time for sorting. Costs can be reduced because it eliminates waste of labor, manpower, and equipment.

In addition, since the soil and foreign matter that causes the crusher malfunction and decreases the crushing efficiency is not introduced into the crusher, there is an effect such as to improve the durability and extend the life of the crusher.

While the invention has been described and illustrated in connection with a preferred embodiment for illustrating the principles of the invention, the invention is not limited to the configuration and operation as such is shown and described. Rather, it will be apparent to those skilled in the art that many changes and modifications to the present invention are possible without departing from the spirit and scope of the appended claims. Accordingly, all such suitable changes and modifications and equivalents should be considered to be within the scope of the present invention.
