Abstract

PURPOSE:To easily and surely disintegrate a waste glass sand concretion by the oscillation of a crushing gate by dropping the concretion from a high placed into a crushing hopper with a crushing grid provided in plural stages at its upper part to crush the concretion by the falling energy, and furnishing the crushing gate at the opening of the hopper at its lower end. CONSTITUTION:A waste glass sand concretion is dropped from a truck 2 into a crushing hopper 3, passed successively through a coarse-mesh first crushing gate 5 and a second crushing gate 6, disintegrated and crushed, and the pulverized material is passed between the comb-shaped rods 9 and 9 of crushing gates 7a and 7b and introduced into a feed hopper 11. The gates 7a and 7b are oscillated upward at intervals to return the oversize from the gates 7a and 7b to the original position corresponding to a receiving rods 10, hence the clearance between the rods 9 and 9 is expanded, and the oversize is crushed by collision with the rod 10 to a small lump of specified size, passed through the gates 7a and 7b and introduced into the hopper 11. The contents of the hopper 11 are dropped on a conveyor 12 and sent to the succeeding stage. The price of a concrete product is reduced in this way.

Description

[Detailed description of the invention]

[00011

[Industrial Field of Application] The present invention relates to an apparatus for crushing waste glass sand material in the form of water-containing nodules produced during the glass manufacturing process. [0002] [Background Art and Problems to be Solved by the Invention] During the glass manufacturing process, abrasive fine powder containing a large amount of 5i(h) is discharged.
It has a particle size of 10μm or less, a Blaine value of 8500c127g, and a moisture content of about 30%, and is generally referred to as siliceous mixed material or glass waste sand material, and has traditionally been treated as industrial waste. It is difficult to handle. [0003] By the way, the above-mentioned glass waste sand material has 5i (h
Because it contains a large amount of , it can be used as a mixing material, bulking agent, and fluidizing agent for concrete products such as piles, hume pipes, wall materials, and boards, as well as for ready-mixed concrete. but,
The discarded glass waste sand material is in the form of clay-like lumps, making it difficult to handle. Also, to use this,
It is necessary to turn it into a dry powder or add it as a slurry liquid when mixing concrete, but producing dry powder requires a large amount of thermal energy and, like cement production, requires a huge amount of equipment. Therefore, the cost becomes high and there is no value in using it. In addition, there is no problem in itself with the method of making a slurry liquid, but once the nodules of waste glass sand material are turned into a slurry, once the flow stops, the surface layer of the liquid hardens within 10 minutes. Due to its nature, the manufacturing equipment cannot be allowed to break down or stop, making it extremely difficult to realize. [00041] The present invention has been proposed in view of the problems of the prior art, and is a novel method for crushing waste glass sand material used to effectively utilize waste glass sand material generated in the glass manufacturing process. The purpose is to provide equipment. [0005]

[Means for Solving the Problems] As a result of extensive studies to solve the above problems, the present inventor has devised a method for crushing the nodules of waste glass sand materials that have been dumped and creating aggregates to be mixed into concrete. It has been found that if it is made into small particles, it can be sufficiently used as an admixture or bulking agent for concrete. Therefore, as a result of further research on the crushing means for the above-mentioned waste glass sand material agglomerates, it was possible to economically and reliably disintegrate the agglomerates into small particles and to form the apparatus of the present invention. [0006] That is, the glass waste sand material crushing device of the present invention,
To explain this with reference to the drawings corresponding to the embodiments, the present invention utilizes the falling energy of glass waste material to be crushed to crush it, and includes a platform for dropping aggregates of glass waste material. A crushing hopper 3 for receiving the dropped nodules is installed below the hopper 1, and at the upper part of the hopper 3, multiple stages of crushing gratings 5 and 6, each having a weight that is successively smaller than the upper stage, are installed. A pair of crushing gates 7a and 7b formed in the shape of comb blades are provided in the lower end opening of 3, facing each other with the comb blades alternating, and are swingable around horizontal shafts 8 and 8 at the ends, respectively. It is characterized by this. [0007]

[Operation] Waste glass sand material to be crushed is carried into the platform 1 by a truck. Glass waste sand material has a moisture content of approximately 30%.
Although it is a slurry with a viscosity of ±10μ, it is in the form of lumps when brought in by truck. [0008] The agglomerates of the waste glass sand material are dropped toward the crushing hopper 3 located at a considerably lower position than the platform 1. The dropped nodules will strongly collide with the crushing grids 5 and 6 due to their falling energy. First, it hits the coarse-grained crushing grid 5 on the upper stage and is roughly divided, and then hits the crushing grid 6 with smaller meshes and is crushed even more finely. [0009] The crushed glass waste sand material is sent to the crushing gate 7
It passes between the comb blades a and 7b or is crushed and falls into the supply hopper 11. Crushing gates 7a, 7b
Clumps that cannot pass through the crushing gates 7a and 7b will accumulate on the crushing gates 7a and 7b.
. If 7b is swung upward as shown by the chain line in Figure 1,
The gap between the comb blade rods 9 and 9 will substantially expand and fall, and the one that does not fall is the crushing gate 7a. If 7b is returned so that it strongly hits the rod 10, the impact will break the lump and cause it to fall. [00101 The glass waste sand material that has entered the supply hopper 11 is supplied to the carry-out device 12 from its lower end opening, and is sent to another location. [0011] In order to use the waste glass sand material as an admixture for concrete, etc., it is necessary to make it into small particles with a particle size of 10 m/'In or less, which can be achieved with the above crushing device. It is preferable to design the device so that: However, if this is not possible due to equipment costs, etc., the crushed material may be further passed from the equipment to a conventionally commonly used crusher to achieve a predetermined size reduction. [0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic vertical cross-sectional view of the device of the present invention, in which 1 is a platform for dumping lumps of glass waste, and the glass waste is transported from the dumping location to the platform 1 by a truck 2. A crushing hopper 3 that receives the dropped nodules and is located below the platform 1 which is the dumping position of the nodules, that is, a position 1 where sufficient energy for dropping the nodules can be obtained, for example, about 2 m below the platform 1. is installed. [0013] In the upper part of this crushing hopper 3, there is a first stage crushing grid 5 formed by arranging a large number of rods 4, 4 in a grid shape at required intervals, and a similar one located slightly below the first stage crushing grid 5. A second-stage crushing grid 6 is provided, and the first-stage crushing grid 5 is formed coarsely, and the second-stage crushing grid 6 is formed finer than the first-stage crushing grid. In addition, each of the above-mentioned crushing grids 5, 6
In the drawings of the embodiment, the vertical and horizontal rods 4, 4 intersect on the same plane, but this is because the rods 4, 4 are arranged at intervals in one direction, but there are other rods on the lower side. It may be a structure in which the rods 4, 4 in the directions are arranged at intervals to form a lattice at the top and bottom. [0014] Furthermore, at the lower end opening of the crushing hopper 3,
A pair of crushing gates 7a and 7b are provided. As shown in FIG. 2, the crushing gates 7a, 7b are formed into a comb blade shape by having a large number of comb blade rods 9, 9 protruding in parallel at intervals from a shaft rod 8 at one end. The comb blade rods 9, 9 are inserted alternately with the shaft rod 8 on the outside, and the horizontal shaft rods 8, 8 are rotatably attached to the lower end of the crushing hopper 3. Each of the crushing gates 7a and 7b can be swung manually or by power, as shown by the arrow in the figure, about the shaft rods 8 and 8. Moreover, those crushing gates 7a. A receiving rod 10 for preventing the crushing gates 7a, 7b from hanging down is provided below the central portion of the comb blade 7b, extending in the transverse direction of the comb blade rod 9. There is also a method of opening the crushing gates 7a, 7b downward, excluding the receiving rod 10. [0015] Further, below the crushing hopper 3,
A supply hopper 11 having an open bottom end is provided on a delivery device 12 such as a belt conveyor. A transfer device 13 such as a vertical or inclined belt conveyor is connected to the transfer device 12, and its upper end faces above the crusher 14. An inclined sorting sieve 15 is provided below the open lower end of the crusher 14, and particles of 10 mm or less that pass through the mesh of the sorting sieve 15 fall onto a belt conveyor 17 via a hopper 16 provided below. It is then sent to a silo (not shown) and stored. In addition, 10 m that does not pass through 1 sorting sieve 15
Particles larger than m flow down on the sorting sieve 15 and are returned to the crusher 14 by the recycling conveyor 18 to be crushed again. [00161] The crushing apparatus of the present invention is configured as described above, and the aggregates of waste glass sand material dropped from the truck 2 fall into the crushing hopper 3 and pass through the coarse first stage crushing grid 5. The particles are divided and crushed into small chunks while sequentially passing through the second stage crushing grid 6, and the fine pieces are passed through the crushing gate 7a.
, 7b through the comb blade rods 9, 9 to the next supply hopper 11.
will enter. In addition, if a lump cannot pass through the crushing gates 7a and 7b, occasionally swing the crushing gates 7a and 7b upward as shown by the chain lines in FIG. 1 to return them to their original positions against the receiving rod 10. According to the comb blade lever 9,9
As the gap between them widens, the particles collide with the receiving rod 10, passing through the crushing gates 7a and 7b and entering the supply hopper 11 as small pieces of a predetermined size or less. Then, it falls from the supply hopper 11 onto the unloading device 12,
It will be sent to the next process. [0017] In the above embodiment, the crushing grid is provided with two crushing grids 5.6 at the first stage and the second stage, but the number of the crushing grids is larger than that. It can also be used as a step. Further, at the same time, the crushing gates 7a and 7b may be oscillated in a downward direction opposite to that shown in the figure. [0018] Effects of the Invention As explained above, the crushing device of the present invention can process waste glass sand material in large nodules, which are difficult to mechanically divide and crush, by utilizing the falling energy of the nodules. Then, the nodule is dropped and collided with a multi-stage crushing grid with gradually smaller openings, so the nodules can be divided and crushed easily and reliably, without requiring large amounts of power, labor, or special equipment, and efficiently. This means that it can be crushed into small particles at low cost. [0019] Since the crushed glass waste sand material is in a stable state, it can be stored and used when necessary. This small-sized waste glass sand material is suitable for use as an admixture for concrete, making it possible to utilize waste materials and to partially replace cement, which has a high cost weight, thereby reducing the price of concrete products. You will be able to contribute.
