Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a crusher, and more particularly to a structure of a crusher having high crushing efficiency.

[0002]

[Prior art]

 In a general high speed crusher, the fineness of the powder formed by crushing must be adjusted to meet the needs of users.

[0003]

[Problems to be solved by the device]

 However, since the crushing effect of the conventional high-speed crusher depends on the filtering action of the filter net installed in the crushing tank, the filter net is easily damaged by the very large impact force of the raw material. In addition, it is necessary to change the mesh size of the filter mesh according to the granule size required by the user. Furthermore, since particles larger than the mesh size do not pass through the filter mesh, the phenomenon that these large particles block the filter mesh frequently occurs, and it is inconvenient to constantly clean the filter mesh. In addition, since the powder is taken out directly from the crushing tank through the filter net, it is difficult to make the fineness of the crushed particles smaller than a certain size, and the crushed particles do not pass through the bottleneck or the state of the cotton thread. It is a problem of the conventional high speed crusher that the crushed particles cannot be made smaller than the crushed particles.

The main object of the present invention is to provide a crusher capable of adjusting the size of crushed particles without using a filter net. Another object of the present invention is to provide a highly efficient crusher structure.

[0008]

[Effect of action and device]

 According to the crusher according to the first aspect of the present invention, the raw material charged into the hopper by the manual or automatic feeding device enters the crushing tank through the feed pipe and becomes powder by the collision with the rotary blade and the crushing action. The air flow generated by the high-speed rotation of the impeller and the flow guide plate guide this powder to the sorting channel and collect it in the storage tank. Particles with insufficient fineness cannot be passed through the sorting channel by the air flow and return to the grinding tank to be further ground. By repeating this process, the particles can finally pass through the sorting channel. That is, only particles that have passed through the sorting channel are collected in the storage tank. For this reason, there are effects that the quality is stable, no filtering net is used, and the possibility of failure is small.

Further, according to the crusher according to the second aspect of the present invention, the size of the particles can be controlled by adjusting the gaps between the inlet pipe, the outlet pipe, the conduit and the pressure control ring. . The smaller this gap, the smaller the air volume drawn from the feed tube when the impeller rotates at high speed, so only finer powder passes through the sorting channel. Conversely, the larger this gap, the thicker the powder will be through the sorting channel. This allows the size of the particles to be controlled. In other words, by adjusting the gap, the air flow that occurs when the impeller rotates changes in intensity. This has the effect of allowing different particles to be sorted while controlling the particle specifications.

Further, according to the crusher of claim 3 of the present invention, by circulating the cooling water, the temperature of the crusher rises when the crusher is operated. It has the effect of preventing sticking.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. First, as shown in FIGS. 1 and 2, a U-shaped base 21 is attached to the upper portion of the motor body 1 with bolts 11. A crushing tank 22 having a recess on the bottom surface is placed so as to be fitted on the base 21. The inner wall surface 221 of the crushing tank 22 is hollow. The outer wall of the crushing tank 22 has two tap holes 222 of different altitudes. Each tap hole 222 is connected to the pipe joint 23, and the cooling water that has entered from the lower pipe joint 23 is stored inside the wall surface 221 of the crushing tank 22, and when it reaches a certain level, the upper pipe joint 23 Is discharged. In the grinding tank 22, when the rotary blade 14 which is fastened with the cap 12 to the half-moon shaped shaft 13 of the motor 1 grinds the raw material, it is known that fine particles adhere to the wall of the grinding tank 22 due to the temperature rise. Prevent with water. Moreover, since both ends of the rotary blade 14 are relatively bent up and down, the raw material from the feed pipe 5 can be ground into fine powder at high speed.

The impeller 15 is fastened to the half-moon shaped shaft 13 of the motor 1 like the rotary blade, and the wind pressure generated by the rotation of the impeller 15 pushes the fine particles into the storage tank 31. A screw hole for fastening the positioning tube 32 is provided on the bottom side of the storage tank 31. A washer 33 below the storage tank 31 is fastened in combination with a positioning tube 32 protruding through the storage tank 31.

Below the washer 33, an annular flow guide plate 34 that is fitted into the crushing tank 22 in combination with the positioning tube 32 is provided. The bottom surface 341 of the flow guide plate 34 has an arc shape, and the raw material crushed by the rotary blade 14 enters the sorting channel 43 formed from the conduit 4 and the feed tube 5 along the arc bottom surface 341. The conduit 4 is fitted into the positioning tube 32 with the positioning tube 32 supporting the upper flange 41. Since the inner surface of the conduit 4 has a tapered shape with a wide upper part and a narrow lower part, the gap between the feed pipe 5 and the conduit 4 inserted into the conduit 4 is also formed as a selection channel 43 with a wide upper part and a narrower lower part. It

The feed pipe 5 is connected to the inner screw of the double-sided screw 62 by the upper screw 51. When the double-sided screw 62 and the lid 61 are coupled with each other by the screw on the outside of the double-sided screw 62, the double-sided screw 62 protruding above the lid 61 is further screw-coupled with the cap 63. The tube 5 and the lid 61 are tightened.

The hopper 7 is a recess provided inside the upper part of the double-sided screw 62 and is mounted on an annular tank 621 having a flat surface. The pressure adjusting ring 53 is screwed to the screw 52 in the middle portion of the feed pipe 5, and the wind pressure of the selection channel 43 can be controlled by adjusting the position of the pressure adjusting ring 53 up and down. The blowout pipe 35 is provided on the side wall of the storage tank 31, and the adjusting blade 352 controlled by the rotary lot 351 is arranged in the blowout pipe 35. When the adjusting blade 352 rotates, the diameter size of the blower tube 35 is changed. A projection 353 is formed on one end of the blow-out pipe 35, and the blow-out pipe 35 and a bag made of cloth or the like can be connected by this projection 353. An air inlet pipe 36 having a smaller diameter than the air outlet pipe 35 is provided at a position facing the air outlet pipe 35 of the storage tank 31. Inside the air intake pipe 36, adjusting blades 362 controlled by the rotary lot 361 are arranged in the same manner as the air exhaust pipe 35, and the diameter of the air intake pipe 36 can be controlled by the adjusting blades 362. .

When the impeller 15 is operated at high speed, due to the principle of fluid dynamics, air is sucked from the feed pipe, and this air is guided to the blades of the impeller 15 and the radius of the air flows along the tangent line of the impeller 15. It flows outward and is separated from the periphery of the impeller 15. That is, the rotation of the impeller 15 causes the airflow to enter from the feed pipe 5, is guided by the blades of the impeller 15, and circulates between the impeller 15 and the wall surface of the crushing tank 22. Since the crushing tank 22 is air-tightly fitted with the flow guide plate 34, this air flow is always guided by the arc-shaped bottom surface 341 of the flow guide plate 34, enters the selection channel 43, and further passes through the storage tank 31 and the blowout pipe. Get out of 35. That is, the fluid formed by the rotation of the impeller 15 enters through the feed pipe 5, passes through the crushing tank 22, the selection channel 43, and the storage tank 31, and is exhausted through the blowout pipe 35.

The raw material charged into the hopper 7 by a manual or automatic feed device enters the crushing tank 22 via the feed pipe 5. The raw material, which has become a fine powder in the crushing tank 22 due to the collision with the rotary blade 14 and the crushing operation, is always transmitted to the air flow and enters the storage tank 31 through the selection channel 43. Particles that have not been sufficiently finely crushed cannot flow through the sorting channel 43 by being carried by the air flow, so they naturally fall into the crushing tank 22 again and are further finely crushed. By repeating this, they can finally pass through the sorting channel 43. Then, it enters the storage tank 31. Therefore, according to one embodiment of the present invention, only the particles that have passed through the selection channel 43 are collected, so that not only the particle size can be selected, but also the standard and quality are stable, and since no filter net is used, a failure occurs. Possibility can be reduced.

A storage tank having a cloth pipe or a ventilator is attached to the air outlet pipe 35. By using a ventilator or a cloth tube according to the amount of raw material, it is possible to smoothly take out the powder with the required fineness. When a cloth tube is used, the air intake tube 36 is closed. This is because the airflow just comes out of the air outlet pipe 35, and in the air outlet pipe 35, a small amount of crushed particles carried by the airflow are all collected and there is no possibility of leaking to the outside.

When the diameter of the blow-out pipe 35 is adjusted to be smaller by the adjusting blades 352 and the gap formed between the conduit 4 and the pressure-regulating ring 53 is made smaller, the impeller 15 rotates at high speed. Since the amount of air sucked from the feed pipe 5 is small, only finer powder can pass through the selection channel 43. Conversely, the larger this gap, the more coarse the powder will pass through the screening channel 43. In this way, the grain size can be controlled.

When the amount of raw materials is large, a storage tank having a ventilator is attached to the end of the blow-out pipe 35 to extract crushed particles. At this time, when the air inlet pipe 36 is opened and the air flow is passed through the ventilator, the powder is collected in the storage tank through the air outlet pipe 35. In this way, the granularity can be controlled by adjusting the gaps between the inlet pipe 36, the outlet pipe 35, the conduit 4, and the pressure adjusting ring 53. By reducing this gap, a finer grain size is selected.

Since the feed pipe 5 and the conduit 4 are parts for switching in this invention, the height of the flange 41 at the upper part of the conduit 4 is increased or decreased, or the position of the screw 52 at the middle part of the feed pipe 5 is changed. If changed, the length of the selection channel 43 becomes longer or shorter. FIG. 4 shows an example of a state in which the height of the flange 41 'of the conduit 4'is lowered and the position of the screw 52 in the middle portion of the feed pipe 5 is lowered to shorten the length of the selection channel 43'. Show. This also reduces the flow path of the raw material to the sorting channel 43 ', so that an appropriate air flow can be selected depending on the nature of the raw material.
