Description

Briquetting Device {BRIQUETTING APPARATUS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a briquetting device, and more particularly, to a briquetting device for compression-molding an unsuitable resource in the form of powder or granules into a desired shape and size and recycling it as a resource.

There is a need for a molding machine that manufactures briquettes in order to recycle various wastes and fine powder resources generated at industrial sites due to depletion of existing resources and price increases.

In order to mass-produce powder raw materials into briquettes having a high density and adequate strength, it is necessary to develop a raw material supply device that supplies uniform distribution and pressure to the raw material to be supplied to the briquetting roll. Operation requires the development of briquetting rolls that have less stress variation during compression and can withstand high temperatures and harsh conditions.

In relation to the conventional raw material supply apparatus, many documents such as Japanese Patent Application Publication JP05339656 disclose various methods and apparatuses for applying uniform distribution and pressure to raw materials. However, satisfactory results in securing uniform distribution and uniform pressure of the raw materials have not been obtained, and have a form unsuitable for mass production.

In addition, a number of materials, including US Patent Publication No. 3969062, related to briquetting rolls, suggest various types of segment rolls.

However, they do not obtain the expected life extension effect at high temperatures and harsh conditions, so they need to be replaced frequently, resulting in a slight reduction in production cost.

Japanese Patent Publication JP05339656 United States Patent Publication No. 3969062

An object of the present invention is a raw material supply means for supplying a raw material with a uniform distribution and compressive stress secured to the briquetting roll, the stress variation during compression for low life and economical operation of the briquetting device, and withstands high temperature and harsh conditions It is to provide a briquetting device that can produce a briquette of excellent quality by providing a briquette roll that can be.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not restrictive of the invention, There will be.

Briquetting device of the present invention for achieving the above object is arranged in parallel side by side, a pair of briquetting rolls to rotate in from the outside and compression molding the raw material; A charging hopper positioned above the briquetting rolls to store raw materials; And a plurality of charging screws placed in an inclined space along the length of the briquetting rolls in the charging hopper to charge the raw material of the charging hopper between the briquetting rolls.

The charging screws may be inserted at an acute angle to the left and right about the YZ plane which is perpendicular to the plane XZ plane of the briquetting roll axis.

The left and right acute angles of the charging screws are 5? It is preferable that it is 25 degrees.

The charging screws may have the acute angle and a zigzag or center screw may be disposed on the left side and an outer screw on the right side.

The charging screws may be inserted at an acute angle from side to side with respect to the XY surface which is the front surface of the briquetting roll.

The left and right acute angles of the charging screws are 3? It is preferable that it is 7 degrees.

The left and right acute angles of the charging screws are 9? May be 25 °.

In the arrangement of the three charging screws, the one charging screw is vertically erected, and the remaining two charging screws can be leaned left and right by the acute angle about the one charging screw.

The charging hopper may be further provided with one or more raw material supply means having a feed screw for supplying the raw material to the charging hopper.

The raw material supply means is characterized in that the feed screw is 30? It should be installed with an angle of 90 °.

The raw material supply means may be installed opposite to each other on the left and right sides of the charging hopper.

The charging screws may further form grooves located between the blades.

The charging screws have a sharp tip, and the blade is connected to the tip of the tip.

The charging hopper may further include a guide tube extending downwardly to guide charging of the raw material, and the guide tube preferably has an inclined end portion.

The angle of the inclined end is 5? It is good that it is 30 degrees.

The briquetting roll may have a structure in which segments having molding pockets are arranged along the circumference of the roll shaft.

Cooling water passages may be further formed on the briquetting rolls.

Preferably, the cooling water flows in from the center of the roll shaft, passes through the segments in a zigzag, and then discharges back to the center of the roll shaft.

The segment may be asymmetrical in shape.

The angle of the stepped surface of the roll shaft mounting the segment and the surface of the segment facing the stepped surface is 50? With respect to the rotational direction of the briquetting roll. It may be formed in the range of 90 °.

The briquetting roll is further provided with a ring liner for biting and fixing the segments, and the bent edge portion of the ring liner that bites the segments is preferably tapered.

The segments may form the molding pocket in the roll shaft such that the arrangement of the molding pockets has an oblique shape or a V-shape.

The charging hopper may be further provided with a fuel supply control plate for adjusting the amount of raw material supplied to the briquetting roll.

The fuel supply control plate is preferably to control the amount of raw material by adjusting the size of the outlet of the charging hopper.

On the other hand, the briquetting device of the present invention is arranged side by side in parallel, a pair of briquetting rolls for rotating the inside in the compression molding; A charging hopper positioned above the briquetting rolls to store raw materials; And a rotary dispersing sphere installed to rotate inside the lower portion of the charging hopper to disperse the raw materials into the briquetting rolls.

The rotary disperser may include a plurality of wings arranged along the circumference.

The rotary dispersion sphere may be made of a smooth roll shape.

One rotation dispersing sphere may be installed between the briquetting rolls, or two may be installed to correspond to the briquetting rolls, or three may be installed to form a triangle.

According to the present invention, the charging screws for charging the raw materials are arranged at right angles to the left and right about the YZ plane, which is perpendicular to the briquetting roll axis plane XZ plane, or arranged V-shaped about the XY plane. Therefore, it is possible to secure a sufficient space for arranging the motor of each charging screw alone in the upper portion of the charging hopper to obtain a strong screw driving force, it is possible to arrange the raw material supply port of the charging hopper on the upper side. This makes it possible to manufacture products with low quality deviations in the strength of briquettes during briquetting operations.

In addition, the charging screw is installed perpendicularly to the XZ plane of the briquetting roll axis plane or at an acute angle to the YZ plane that is perpendicular to the briquetting roll axis plane to apply uniform pressure to the feedstock, thereby being sensitive to the change in extrusion stress due to the variation of the raw materials. Hydraulic pressure can be finely adjusted.

In addition, the raw material supply means for uniformly supplying the raw material into the charging hopper for charging the raw material into the briquetting roll is a compressible raw material that is adhesive or relatively low in specific gravity and compressible through a feed screw installed at an acute angle to the charging screw in the charging hopper. By supplying the to the charging screw in the charging hopper, it is possible to uniformly supply a relatively large amount of raw materials in the compressed state.

In addition, the charging screw supplied to the briquetting roll by applying a uniform pressure to the raw material in the charging hopper has a uniform groove between the blades, that is, the lower portion and the blade is connected to the tip end, which is relatively large compared to the existing shape The raw material can be supplied, so that a large compressive stress of the raw material can be applied. Since the blade is connected to the tip end, the variation of the compressive stress to the core material can be minimized, so that the compressive stress can be applied relatively uniformly when feeding the raw material into the briquetting roll gap.

The charging hopper also has a guide tube that guides the raw material at a uniform pressure towards the briquetting roll gap. At this time, since the end of the guide tube has an appropriate angle with respect to the briquetting roll axis plane, it is possible to secure a relatively uniform stress by leveling out the compressive stress variation of the raw materials generated by the two or more charging screws.

In addition, the briquetting roll is installed in the cooling water passages in the segment portion and the shaft portion to ensure sufficient cooling to maintain the mechanical properties of the material steel grade even at high temperatures to maximize the life. In addition, when the segment is formed in an asymmetrical shape and requires a high compressive and strong compressive stress for the raw material having a high compressibility, there is no separation that induces detachment of the segment attached to the shaft. In addition, by fixing the segment by attaching the ring liner with the tapered edge portion, it is easy to prevent the separation of the segment and to secure a good roundness.

In addition, the forming pockets of the segments are arranged in an oblique (V) shape, a V-shape or an inverted V-shape to reduce the variation of the hydraulic pressing stress of the briquetting roll that is hydraulically adjusted during briquetting. This significantly improves the service life of the equipment and allows the production of uniform briquettes.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like elements in the figures are denoted by the same reference numerals wherever possible. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

As shown in the figure, the briquetting device of the present invention obliquely inserts the charging screws 20 into the charging hopper 10.

Conventionally, the charging screws 20 are arranged side by side vertically to form a type II, in this case, because the gap between the charging screws 20 can not be sufficiently secured to secure a uniform raw material supply pressure, And a heavy width (eg, a roll width: 700 mm or less) of the briquetting roll 60.

In addition, a gearbox drive system in which two drive shafts come out due to insufficient space for disposing the motor 30 of each of the charging screws 20 alone on the top of the charging hopper 10 to drive the charging screws 20. Since the fuel supply port 13 formed on the charging hopper 10 has to be located at the side of the charging hopper 10, the arrangement is determined according to the shape of the raw material supply line and the position of the drive system. there is a problem.

Thus, as shown in Fig. 1 and Fig. 2, the present invention, the charging screws 20 to the acute angle (A, A ') to the left and right about the YZ plane perpendicular to the XZ plane of the axial plane of the briquetting roll 60. To place. As a result, a sufficient space for disposing the motor 30 of each of the charging screws 20 alone can be secured to the charging hopper 10 so as to strongly drive the charging screws 20, and a raw material supply hole ( 13) can be placed on top.

At this time, the left and right acute angles (A, A ') of each of the charging screws 20 around the YZ surface is preferably set to 5 ~ 25 °. If it is less than 5 ° it is impossible to secure a sufficient free space on the top of the charging hopper (10), and if it exceeds 25 ° to ensure a uniform raw material supply pressure between the briquetting roll 60 due to excessive inclination of the charging screws (20) It becomes difficult. More preferably, the left and right acute angles of the charging screws 20 around the YZ plane are set to 10 to 25 degrees. For this reason, it is possible to manufacture a product with less quality variation during the briquetting work.

When the briquetting roll 60 is wide (eg, roll width: 700 mm or more), three or more charging screws 20 should be disposed to secure a strong raw material supply pressure.

In this case, as shown in FIG. 3, when three charging screws 20 are required, two charging screws 20 have a left angle and one charging screw 20 has acute angles A and A 'on the right, respectively. When the four charging screw 20 is required, as shown in Figure 4, two charging screw 20 is to the left, the other two charging screw 20 to be arranged in a zigzag form on the right side. Two centers can be arranged on the left and two outsides on the right.

Alternatively, as shown in FIG. 5, the charging screws 20 may be arranged in a V shape. When the charging screws 20 are arranged in a V-shape, sufficient space for arranging the motor 30 of each charging screw 20 alone on the charging hopper 10 can be secured to make the screw 20 strong. Can be driven, there is an advantage that the raw material supply port 13 can be arranged on the top.

At this time, the acute angles B and B 'of the left and right loading screws 20 around the XY plane which is the front surface of the briquetting roll 60 are set to 3 to 7 °. When the acute angle (B, B ') is 3 ~ 7 °, it is possible to secure a free space on the top of the charging hopper 10 and, when the briquetting roll 60 is a medium width, uniformity of the raw material supplied to the roll 60 One pressure can be secured.

In addition, when the briquetting roll 60 is narrow, it is preferable that acute angles B and B 'are 9-25 degrees. When the acute angle (B, B ') is 9 to 25 °, fine adjustment of the hydraulic pressure of the briquetting roll 60 is advantageous, and also there is an advantage that sufficient free space can be secured on the charging hopper 10.

In addition, when the briquetting roll 60 is wide (eg, roll width: 700 mm or more), three or more charging screws 20 need to be arranged to secure a strong raw material supply pressure, for example, as shown in FIG. It may be arranged in the form of ↘ ↓ ↙. That is, one charging screw 20 may be disposed vertically, and two charging screws 20 may be disposed inclined left and right by acute angles B and B 'with respect to one charging screw 20. .

As shown in FIG. 7, the raw material supply means 40 for uniformly supplying the raw material into the charging hopper 10 for charging the raw material into the briquetting roll 60 is installed at the side of the charging hopper 10. The raw material supply means 40 serves to supply adhesive or relatively low specific gravity and compressible raw materials to the charging screw 20 in the charging hopper 10 through the supply screw 41 rotating by a driving force such as a motor. do.

As such, the raw material supply means 40 installed on the side of the charging hopper 10 has a number of one or more, for example, up to four, to increase the amount of production of the raw material and to increase the product yield. (For example facing each other), so that the feed screw 41 axis angle (C) from the axis of the charging screw 20 in the charging hopper 10 is 30 ° to 90 °, that is in the horizontal supply form Can be installed in various ways in the form of oblique supply.

In order to supply the raw material with a high specific gravity uniformly, it is preferable that the supply screw 41 axis angle C is installed at 60-90 degrees from the charging screw 20 axis. It is possible to select and install this angle according to specific gravity of raw material (refer FIG. 8).

In addition, in order to supply the raw material with a small specific gravity uniformly up to the primary compression, it is preferable that the supply screw 41 axis angle C is set to 30 to 60 °. At this time, the size of the raw material inlet 42 is relatively larger than the size 43 of the cylinder surrounding the supply screw 41, so that more of the raw material can be uniformly supplied in a compressed state (see FIG. 8).

On the other hand, as shown in Figure 9 and 10, in the case of incompressible fine powder or relatively high specific gravity, or in the case of briquetting non-tacky raw material, the present invention is a small wing 71 in the circumferential direction instead of the charging screw 20 Is equipped with a rotary dispersion sphere 70 can be mounted to the charging hopper (10).

Rotating dispersion sphere 70 is uniformly distributed while rotating the raw material downward by gravity at the top to feed between the gap between the briquetting roll 60, effectively suppressing the bridge (Bridge) phenomenon of the raw material in the charging hopper 10 .

The rotary dispersion sphere 70 can increase the uniform dispersion supply effect of the raw material by installing the number from one to three as the characteristics of the raw material, that is, the degree of incompressibility, specific gravity, and non-adhesiveness increases.

For example, as shown in FIG. 9, one rotational dispersing sphere 70 is provided between the briquetting rolls 60, or two are disposed corresponding to the briquetting rolls 60 as shown in FIG. 10. Alternatively, as shown by the dotted line, three may be installed to form a triangular shape to increase the effect of supplying uniform dispersion of raw materials.

On the contrary, in order to further increase the briquette compressive strength of the raw material having the above characteristics, as shown in FIG. 11, the rotary dispersion sphere 70 may be installed to have a smooth roll shape without a wing 71. have.

The rotary dispersion sphere 70 in a roll form supplies raw materials between the briquetting rolls 60 after the first compression, whereby the primary compressed raw materials are excellent in strength when subjected to the second strong compression on the briquetting rolls 60. Briquettes can be prepared. Two rotation dispersion spheres 70 are provided to correspond to the briquetting rolls 60, respectively, and feed the raw material downward by gravity between the rolls 60.

This rotary dispersion sphere 70 rotates outward and supplies the raw material to the briquetting rolls 60.

As shown in FIGS. 12 and 13, the charging screw 20 has a uniform groove 22 below the blade 21, that is, a portion between the blades 21, and the blade up to the tip end 23 with a sharp tip. It is preferable that it consists of the form which (21) continues.

As shown in FIG. 12, the uniform grooves 22 under the blades 21 can supply more raw materials than the existing flat shapes, thereby applying a large compressive stress of the raw materials.

12 is a graph comparing the compressive stress of the raw material when using the conventional charging screw and the charging screw 20 of the present invention. When using the charging screw 20 of the present invention compared to the conventional charging screw it can be seen that the compression stress of the center of the charging screw 20 as well as the blade 21 shows a higher compressive stress than the existing charging screw.

In addition, since the blade 21 of the conventional screw is not connected to the tip end 23, when the raw material is supplied, the compressive stress is concentrated in the circumferential direction at the end of the blade 21, and the raw material pressure at the center is low to compress in the radial direction. Stress deviations occurred.

As shown in FIG. 13, the charging screw 20 of the present invention has a blade 21 connected to the tip end 23, thereby minimizing the variation of the compressive stress to the center raw material, thereby minimizing the raw material to the gap of the briquetting roll 60. When supplied, a relatively uniform compressive stress can be applied.

Figure 13 shows a graph comparing the compressive stress of the raw material when using the conventional screw and the charging screw 20 of the present invention. When using the charging screw 20 of the present invention compared to the conventional charging screw, the compressive stress at the end of the blade 21 is the same, but the compressive stress at the center of the charging screw 20 shows a higher compressive stress than the existing charging screw. .

Therefore, the charging screw 20 of the present invention can increase the compressive stress of the raw material when applied to the briquetting device to produce a briquette having a high density and uniform strength.

As shown in FIG. 14, the charging hopper 10 includes a guide tube 50 extending downwardly to guide the raw material at a uniform pressure toward the briquetting roll 60. The lower end of the guide tube 50, that is, the lower end forms the inclined end 51, and the angle D of the inclined end 51 becomes 5 to 30 degrees with respect to the axial plane XZ of the briquetting roll 60. This is preferred.

As shown in Fig. 14A), when the lower surface of the guide tube 50 is made parallel to the axial plane XZ of the briquetting roll 60, the maximum minimum deviation of the average compressive stress of the two charging screws 20 Is a big phenomenon.

On the other hand, as shown in Figure 14b), if the lower surface is manufactured to the angle (D) 5 ~ 30 °, the compressive stress variation of the raw material generated by the two or more charging screws 20 significantly reduced to relatively Uniform stress can be secured. If the angle D is less than 5 °, sufficient deviation reduction effect cannot be obtained, and if the angle D exceeds 30 °, the deviation of the compressive stress increases.

As shown in FIG. 15, the briquetting roll 60 is a segment type roll attaching the segments 63 in which the pocket 63a is machined to the roll shaft 61. The briquetting roll 60 is provided with a cooling water passage 90. When the cooling water passage 90 is installed only in a part of the roll shaft 61 adjacent to the segment 63 during briquetting at a high temperature, the segment 63 is removed. There is a problem that the segment 63 is not sufficiently cooled because it is cooled in an indirect manner.

Therefore, when the temperature of the segment 63 rises above the austenite reverse transformation temperature of the steel grade, part of the martensite tissue at room temperature or most tissues are reverse-transformed into austenite when used for a long time, so that mechanical properties, in particular, The wear resistance is significantly reduced, resulting in a decrease in lifespan.

Thus, in the present invention, the cooling water passage 90 is installed to penetrate the segment 63 directly so that sufficient cooling is achieved. The cooling water path 90 is formed by forming a flow path 91 penetrating the segment 63 and connecting the flow path 91 to the tubular body 93 from the outside.

As a result, the segment 63 does not rise above the austenite reverse transformation temperature even when used for a long time at a high temperature, thereby maximizing the life by maintaining the wear resistance, which is a required mechanical property of the steel grade.

In addition, as illustrated in FIGS. 16 and 17, when the cooling water passage 90 passes through the segments 63 and the roll shaft 61 alternately, a better cooling effect may be obtained. The cooling water path 90 has a structure in which cooling water flows from the center of the roll shaft 61, passes all the segments 63 of the surface of the roll shaft 61 in a zigzag direction, and is discharged back to the center of the roll shaft 61. Achieve.

As shown in FIG. 18, the shape of the segment 63 is generally symmetrical in the circumferential direction, but is attached to the roll shaft 61 when strong compressive stress is required for a material having high specific gravity and high compressibility. Asymmetry may be used since spacing may occur which leads to the separation of the segment 63.

In this case, the shape of the roll shaft 61 and the rear surface of the segment 63 may be formed in various shapes having an angle E of 50 to 90 ° with respect to the rotational direction so as to have a strong correspondence to the rotational direction of the roll 60. .

That is, the angle E of the step surface 61a of the roll shaft 61 on which the segment 63 is mounted and the back surface 63b of the segment 63 facing the step surface 61a is the briquetting roll 60. 50 to the direction of rotation It may be variously formed in the range of 90 °.

As shown in FIG. 19, when the segments 63 are attached to the surface of the roll shaft 61 by various bolting methods, it is difficult to secure the roundness of the final roll 60 to which the segments 63 are attached. .

The present invention installs a ring liner 80 that bites and secures the segments 63, while the bent edge portion 81 that tapes (abuts) the segments 63 installs the tapered ring liner 80. The roundness of the segments 63 attached to the roll shaft 61 by bolting is ensured. Therefore, when the ring liner 80 is mounted, it is easy to prevent the separation of the segment 63 and to secure a good roundness.

As shown in Figs. 20 and 21, the segments 63 have a molding pocket 63a such that the arrangement of the molding pockets 63a in the roll shaft 61 has an oblique shape or a V-shape. Form.

That is, the surface pocket 63a of the segment 63 is arranged on the roll shaft 61 in a diagonal (/) shape, a reverse V shape, and a V shape to adjust hydraulic pressure during briquetting. By reducing the deviation of the hydraulic pressing stress of the briquetting roll 60 is significantly improved the life of the equipment.

Pocket 63a exhibiting the greatest compressive stress when the raw material is introduced into the pocket 63a and compressed in the briquetting operation using the briquetting roll 60 in which the molding pocket 63a is arranged in a straight line (-). Since the rear 2/3 to 3/4 points of) are applied at the same time as the number of pockets 63a, different front and rear points and large compressive stresses are different.

However, as shown in Figs. 20 and 21, when the forming pockets 63a are arranged in the form of /, ∧, ∨, the rear 2/3 to 3/4 points of the pocket 63a are not at the same time. As the rotation of 60) is sequentially performed, the position of the pocket 63a of the large portion and the small portion of the compressive stress is continued at the same time, thereby exhibiting a relatively large deviation of the compressive stress compared to the straight type (-) method.

This reduction in compressive stress variation can significantly improve the life of the briquetting equipment and can also produce a uniform briquette.

In order to produce high quality briquettes of high density and strength, conditions such as moisture, ingredients, particle size, etc. of raw materials must be supplied at a constant state. However, in the industrial field, if the desired homogeneity cannot be secured during the change of the state of the initial raw material, the drying process such as the front end of the briquetting equipment, the screening of the raw material, the crushing process, and the mixing of the provider, the uniformity in the post-briquetting process Can't get quality briquettes. Therefore, the briquetting equipment makes efforts to minimize the quality variation of the briquette due to the heterogeneity of the pre-process by adjusting the raw material supply amount, the hydraulic pressure of the roll, the speed of the screw feeder.

As shown in Figure 22 and Figure 23, in order to effectively control the amount of raw material supplied to the roll 60, it is preferable to mount the raw material supply control plate 110 on the side of the charging hopper (10).

As shown in FIG. 22, the raw material supply control plate 110 enters into the gap of the roll 60 to reduce the amount of raw material supplied to the roll 60, and in the gap of the roll 60 to increase the amount of raw material. The amount of feedstock can be controlled by retracting as much as possible. As such, the raw material supply control plate 110 controls the amount of fuel by adjusting the size of the fuel outlet of the charging hopper (10).

As shown in FIG. 23, the raw material supply control plate 110 may be installed at both left and right sides of the charging hopper 10 to increase the capability of adjusting the raw material supply amount.

On the other hand, the shape of the raw material control plate 110 is the manner in which the control plate 110 is inserted and retracted as shown in Figure 22 and 23, and as shown in Figure 24 of the control plate 110 of the charging hopper 10 side The upper part is fixed to rotate like a clockwork, and the lower tip portion is pushed into the push rod 120, as shown in FIG. 25, the entire adjustment plate 110 is pushed into the push rod 120, it is possible to insert the drawer type. As illustrated in FIGS. 24 and 25, the raw material supply control plate 110 may be installed at both left and right sides of the charging hopper 10 to increase the capability of adjusting the raw material supply amount.
