Description

Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the Invention (/) Summary of the Invention: The present invention relates to an improved head anti-rotation and sealing system for a rotary crusher. The system of the present invention is particularly suitable for use in conjunction with a rotary crusher of the type disclosed in Australian Patent Specification No. 618545 (AU-B-l9935 / 88). However, although it will be described that Qiuyou Qiu is a crusher of the old miscellaneous type, it should be noted that this system is also used; other types of rotary crusher. Australian Patent Specification No. 6! 8545 describes the rotary crusher. When the crusher head rotates along the central axis, the crusher head is applied without any resistance under the crusher head. Rotating motion transmitted to the head rotates relative to the cup and the main shaft. It is further mentioned that when a fragile or fragile material is placed in the crushing chamber defined by the cup and is received within the annular gap between the cup and the head, the material will easily resist the head against the The rotation of the cup. When no fragile or fragile material is stored in the crushing chamber, if the head is not restricted, most of the heads of the rotary crusher will rotate relative to the cup. By means of standard ball and roller bearings, the head of the crusher is installed and supported, and the ball and roller bearings rotate at almost the speed at which the drive shaft rotates. This rotation is not necessary because: (1) Unnecessary rotation of the head is an avoidable dangerous situation for the operator. (2) During the operation of the crusher, the distance between the crushing head and the cup is called the closed side setting (CSS), and the closed side setting can be determined 4

Order ---------- Line L 476670 A7 B7 V. The size of the description of the invention (α) (please read the precautions on the back before filling in this page). When it is necessary to keep the size of the product within the required range, the closed-side setting 値 (css) must be adjusted. Usually, the closed-side setting 値 (CSS) can be monitored by regular measurement 'and in many crushers In the installation method, the most convenient adjustment method is when the crusher does not feed the raw material, the soft deformable material, such as lead, lowered onto a suspension line enters the crushing chamber. After the soft deformable material is pressed over 1, the material is drawn back by raising the suspension wire, and the thickness is measured to determine the closed-side setting css. In other installation methods, the deformable material can be dropped into the crushing chamber and taken out from the lower side of the crusher to measure its thickness. However, when the head is rotated at a near-revolving speed, the above monitoring steps cannot be performed. It is very dangerous to lower a suspended object into the crushing chamber. 'In any application example, the rotating action will distort the deformable material', making it impossible to correctly measure the closed side setting. (Css) ° Intellectual Property Bureau, Ministry of Economic Affairs Printed by the employee consumer cooperative (3) If the head of an empty crushing chamber rotates at a near-revolving speed, it will block the input of new feed material, and the crushing chamber will be excessively worn. First of all, the newly fed material will be discharged by the centrifugal force transmitted from the head. Secondly, when the moment of inertia (energy) of the head is absorbed, the head and the cup are subjected to premature grooving abrasion caused by the newly fed material. From the above reasons "when the crusher is operating together with the empty crushing action chamber", the natural tendency of the crushing head to rotate is unacceptable to the industry. Therefore, there is a need for a head anti-rotation device. In particular, it relates to the rotary crusher of the type of Australian patent No. 618545, but it is also related to other models regardless of the type, which is described in the Australian patent 5 297 mm) The paper size applies to the Chinese National Standard (CNS) A4 regulations袼 (21〇476670 A7 B7 V. Description of the Invention 〇) to · When the rotary crusher is crushing fragile or fragile materials, The point usually moves in a slightly circular, progressive movement. 'This progressive movement is clockwise or counterclockwise during head rotation (revolving). By applying a large restrictive force, the head that moves in a circular and progressive manner (rotation) cannot be stopped, and it is not suitable to restrict the progressive movement because: (a) the required force is large and the appropriate restriction device must be Larger and more expensive, (b) the restriction device will cause unnecessary slotting and abrasion of the crushing head and the cup caused by fragile and fragile materials, and (c) the crushing head and the cup Normal wear may be uneven, resulting in wear grooves in the cup and head. It allows oversized products to pass through the crusher and mix into products that have been crushed properly, allowing close control of the crushed product grade Becomes impossible. Therefore, when the head is swiveled together with the empty crushing action chamber, the ideal anti-crushing head anti-rotation device must be able to apply a suitable, but minimal limiting force, to keep the head still, without causing rotation. When the crusher operates, it can allow the head to rotate slightly with respect to the cup. A suitable device for this purpose is provided by the cyclone crusher system disclosed in the international patent application PCT / AU95 / 00489 (WO96 / 04993), which is equivalent to Australian Patent No. 684382 and granted to Bayliss, etc. U.S. Patent No. 5,775,607. In its most extensive form, PCT / AU95 / 00489 discloses a rotary crusher, which includes a cup for defining an action chamber for receiving material to be crushed, and 6 paper standards that apply Chinese national standards (CNS) A4 specification (210 X 297 public love) ------------- install (please read the precautions on the back before filling in this page) ini -1-口 τ I in an ni Economy Printed by the Ministry of Intellectual Property Bureau's Consumer Cooperatives 476670 A7 B7 V. Description of the Invention (if) The cup further defines a discharge port located at the bottom of the rotary crusher, and the crushed material can be discharged through this discharge port. The crusher also includes a crushing head which is installed in the cup and is offset from the central axis of the cup, and a driving assembly for driving the crushing head in the cup, It is used to transmit the rotary motion to the crushing head rotating along a rotary axis, which is inclined and staggered relative to the central axis. This configuration mode allows fragile or fragile materials received into the crushing chamber to be crushed between the inner peripheral surface of the cup and the outer peripheral surface of the head by the head rotating motion. The crusher further includes a system for restricting the rotation of the head relative to the cup and the rotating shaft. The system includes: (i) a ring disposed between the area around the lower side of the head and an annular surface of the fixed structure Shaped elastic member, the fixing structure is separated from the surrounding area of the lower side and substantially on the same axis; (ii) for fixing the first edge of the elastic member to one of the ring-shaped areas of the head, and fixing An anchoring mechanism for the annular surface of the structure; (iii) an endless belt of friction material provided around the second edge of the elastic member; and (iv) for applying a force to force the frictional endless belt to separate from the head A ring-shaped area and a ring-shaped surface of the fixed structure are used for the friction contact of the deflector. In this crusher system, when the head is rotated in the room without any material to be crushed, the deflection mechanism is operated to Provide sufficient aforesaid frictional contact to limit the rotation of the head relative to the bearing cup and the rotating shaft. In addition, during the crushing action, the annular area of the other head is fixed by the friction material.

Description of the invention ({) Structure ring surface Sliding between them allows the head to rotate relative to the cup and the pivot axis. (Please read the notes on the back before filling out this page) It is revealed in PCT / AU95 / 00489 that the above advantages are available, and that the rotary crusher has considerable market potential. Thus, the unnecessary rotation of the crushing head provides an effective limit for the crusher system. In addition, the system provides an effective seal between the swivel component and the fixed component. That is, the system is used as a sealed lubricant required by the mechanism inside the crusher, and at the same time prevents the crushed material and other pollutants from the environment outside the crusher from entering the mechanism. Figures 1 and 2 of PCT / AU95 / 00489 illustrate embodiments considered to provide the greatest market potential. The reasons are: (a) The arch-shaped clamping elements that are combined to form the clamping components 76 and 77 are independent of the seal 70, so that if the clamping component is worn or damaged, the seal 70 can be as a separate Component-like replacement. Clamping members 74, 90, 92, and 93 can be reused to clamp a new (replaced) seal 70 to reduce the cost of replacement parts. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs (b) During the operation of the crusher, the spring 97 can set the amount of deflection and the force to limit unnecessary head rotation, and under this condition, the spring is static spring. In this regard, these springs are protected to prevent metal fatigue in springs that are subject to variable deflection during use. It has a long service life. In this regard, the above springs are superior to the article 178 illustrated in Figure 3 of PCT / AU95 / 00489. (c) It is known that the clamping member 93 can be provided with a sealing member 70 that can provide the necessary clamping, and can also be provided on the clamping member 93 and the lower main body member 18a. Specifications (210 X 297 mm) 476670 A7 B7 V. Description of the invention u) Made of suitable and frictional material. Therefore, by reducing the friction lining material in several applications, the manufacturing cost of the clamping assembly can be reduced. However, despite these reasons, all the problems of PCT // AU95 // 00489 are included in the embodiment shown in Figs. Among these problems, the first is caused by the need for a seal 70 made of an elastic material, which will allow the seal to accept the relative movement between the upper part of the crusher and the base part without causing The seal is useless and broken. Although the cost of such metal parts is quite uncompetitive, several suitable metals can also be used. More economical and suitable materials have properties commonly found in oil-resistant rubber and plastics, such as polyvinyl fluoride (PVC) and polyamide. For this reason, rubber and plastic materials are preferred. These materials can tolerate the distortion caused by clamping and can be effectively fixed and maintained in position by clamping. The clamping action also creates a seal between the part being clamped and the part being clamped. However, the application range of the clamp must be tightly controlled to avoid excessive stress on the rubber or plastic and to prevent the rubber or plastic from being squeezed out between the clamping surfaces. For this reason, the clamping members 74, 90, 92, and 93 must be configured to make metal-to-metal or surface-to-surface contact in pairs to prevent the rubber or plastic from being further clamped or squeezed. It must be clamped to provide the exact angle required for clamping, while at the same time effectively preventing over-clamping. The manufacturing tolerances must be quite close to achieve the result of increased production costs. The second problem of the PCT / AU95 / 00489 system is caused by the need to make the shape of the seal with a mold and to provide beads 72 and 73 for clamping. For this reason, the seal is formed by a mold, and then chemical or thermal 9 paper sizes are applicable to Chinese National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling this page )

Description of the invention (leaf) The interior of 18a is anti-rotation The system 12 provides protection by an elastic ring seal. The eccentric shaft 28 is driven by a driving assembly 40, which uses a driving motor (not shown) to rotate the eccentric shaft on the axis of the lower eccentric shaft portion 28a. The driving assembly 40 has a driving shaft 42 mounted on the bracket 18a via the inner bearing assembly 44 and the outer bearing assembly 44a. A pinion 46 is mounted on the inner end of the drive shaft 42 and meshes with a crown wheel 48 fixed around a portion 28a of the eccentric shaft 28. A pulley 50 located at the outer end of the driving shaft 42 enables the driving shaft 42 to be rotated by a motor via a driving belt (not shown) for rotating the eccentric shaft 28. During the operation of the crusher 10, the driving assembly 40 rotates the eccentric shaft 28 on the shaft center of the lower portion 28a. Since the axis of the upper eccentric shaft portion 28b is inclined to the axis of the lower eccentric shaft portion 28a, and because the head 16 is coaxially mounted on the upper eccentric shaft portion 28b, the eccentric shaft 28 is on the axis of the lower portion 28a Rotation on the heart causes the head 16 to rotate around the fixed position P. In addition, since the lower end of the head 16 is disposed close to or in a fixed position P, the turning movement of the head 16 can cause the movement of the upper end thereof to mainly cross the axis of the bearing cup 14, And the movement of the lower end of the head 16 is made substantially parallel to the axis of the cup 14. The material to be crushed is fed into the upper end of the cup 14, and a crushing action chamber 60 defined around the head 16 in the cup 14 is reached. During the rotation of the eccentric shaft 28, the movement of the head 16 provides a crushing effect. 17 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) " (Please read the precautions on the back before filling (This page) One-pack --- order ------------ line 'Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 476670 A7 B7 V.

The figure shows that a particle of the material to be crushed is at position "A", and the gap is :-The largest side is at the radially opposite side of the upper end of the crushing action chamber 60,-at the same side of the lower end of the crushing action chamber 60 (that is, directly below position A) Is the largest chirp, and the radially opposite side (ie, at position "B") at the lower end of the crushing action chamber 60 is the smallest chirp. In addition, when the eccentric shaft 28 rotates, the rotation of the head 16 will cause the positions of the maximum and minimum gap openings on the upper side and the positions of the minimum and maximum gap openings on the lower side to continuously appear on the radial plane of the cup 14. Therefore, when the eccentric shaft 28 is rotated 180 degrees from the position shown in Fig. 1, a maximum gap 値 appears at both the position A and the position B.

The operation of the system 12 will be understood with reference to the previous description. It should be noted that the friction lining 95 is arranged to be frictionally engaged with the surface 75 of the bracket 18a so that as the head 16 rotates, the seal 70, each of the clamping components 76 and 77, and the friction lining 95 Both rotate with the head 16. The spring 97 is configured such that the friction lining 95 is compressed against the surface 75, but the spring 97 need not be stretched and compressed when the head is rotated. Since the bead 72 on the upper side of the seal 70 is directly clamped to the surface 74 of the head 16, if the head moves gradually in a circle, the seal 70 and 19 paper sizes are applicable to China National Standard (CNS) A4 specifications 210 X 297 mm) 1. (Please read the precautions on the back before filling out this page) _ Binding · 476670 A7 B7 5. Description of the invention (q) The head 16 is supported. (Please read the precautions on the back before filling this page) The combined effect of all the springs 97 is sufficient to provide sufficient friction between the lining 95 and the bracket 18a, so that when the head is swiveled in the empty crushing action chamber 60, the head is prevented 16 turns. However, when fragile and fragile materials are crushed, the frictional force cannot prevent the head 16 from moving slowly. The seal 70 excludes dust, moisture, and chemicals, and retains a lubricant. The seal also prevents the crushing head 16 from rotating freely by transmitting the resistance generated by the friction surface and the surface 75 of the lining 95 to the crushing head 16. In Figs. 3 and 4, one of the 'revolving crushers 110 has an anti-rotation system 202 according to the present invention. For convenience, the components of the crusher 110 shown in Figs. 3 and 4 are substantially the same as those of the crusher 10 shown in Figs. 1 and 2, and are represented by the same component symbols plus 100. A simple comparison of Fig. 1 and Fig. 2 with Fig. 3 and Fig. 4 confirms that the type and function of the specified component can be easily understood from the description of Fig. 1 and Fig. 2. Therefore, the further description is mainly limited to the features of the system 202. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economics The system 202 of Figs. 3 and 4 has a ring-shaped elastic seal 204 which has a bead 206 around the upper side and a bead 207 around the lower side. The seal 204 is clamped at the upper bead 206 with respect to the lower peripheral edge of the head 116; at the same time, the seal 204 is clamped at the lower bead 207 with respect to the peripheral boundary of the bracket 118a. In addition to the above, in broad, general terms, the seal 204 is a seal 70 similar to the prior art crusher shown in Figures 1 and 2 of PCT / AU95 / 00489. However, in addition to this, in the seal 204 and the paper size of the seal 20, the Chinese National Standard (CNS) A4 specification (210 x 297 mm) is applicable. 476670 A7 B7 V. Description of the invention (θ) The fixing methods of different beads 206 and 207 are quite poor. Essentially, preferably, each bead 206 and 207 is approximately a semi-circular shape; ^ a radial section of the annular pattern of the seal 204. The configuration of each bead 206 and 207 is similar to provide individually different inner peripheral surfaces 206a and 207a of the convex surface, and a slightly cylindrical outer surface. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs to accommodate the seal 204, a radially outwardly facing peripheral surface U6a bounded by the lower side of a head 116 is provided with a groove 208 opened radially outward. It can be clearly seen from FIG. 4 that the groove 208 has a cross-sectional shape that matches the cross section of the bead 206, so that the surface 206a of the bead 206 can be hermetically supported against the concave surface of the groove 208. Preferably, the beads 206 and the grooves 208 have different peripheral boundaries to enable good surface contact with each other. Since the constituent material of the seal 204 is elastic, the surface contact can be obtained along the periphery of the head 116. However, to maintain the seal 204 relative to the head 116, to provide the necessary seal between the seal and the head, and to transmit torque between the components of the crusher, the bead 206 is clamped to the head 116. To this end, an upper annular clamping member or strap 210 is provided on the cylindrical outer surface of the bead 206, and the clamping member is tightened to firmly hold the bead 206 in the groove radially inward. Inside the slot 208. The system 202 includes an annular plate 212 that is fixedly secured to the bracket 118a. By being located radially outwardly of the peripheral surface 212a of the ring-shaped plate 212, the sealing member 204 can be held with respect to the peripheral boundary of the bracket 118a. The configuration of the clamp is similar to that provided to the head Π6. Therefore, the outer peripheral surface 212a of the annular plate 212 is provided with a cross-section 21 This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 x 297 mm) 476670 A7 B7 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Description of the Invention (d) The shape of the surface is matched with the groove 209 of the cross section of the bead 207, so that the surface 207a of the bead 207 can be carried in a sealed manner against the concave surface of the groove 209. Due to the elasticity of the sealing member 204, the individual different peripheral boundaries of the bead 207 and the groove 209 can again make a good surface contact with each other, and this surface contact can be obtained along the periphery of the annular plate 212. However, for the same reason that the clamping member 210 is provided around the bead 206, an additional clamping member 211 is provided around the cylindrical outer surface of the bead 207, and this clamping member is tightened Hold the bead 207 firmly in the groove 209 radially inward. The annular plate 212 of the system 202 is a simple annular type having grooves 209 formed on its outer surface. By using a plurality of springs 197 mounted on a stepped, annular pressure plate 196 spaced apart from each other along the circumference, the annular plate is biased downwardly toward an upwardly facing surface of one of the brackets 118a. The outer edge 196a of the flat plate on the annular plate 212 can cause the spring 197 to exert a force on the annular plate 212, so that the annular plate is deflected to make a strong frictional engagement with the upper side surface of the bracket 118a. To achieve this, a bolt 198 passes through each of the springs 197 distributed along the surrounding array and a hole 196 through the plate 196 located inside the annular plate 212, and the bolt is locked into the bracket 118a to compress the spring 197 and a biasing force provided through the flat plate 196 are applied to the annular plate 212. The annular plate 212 corresponds to the holding member 77 in the prior art arrangement shown in Figs. 1 and 2. Compared with the simple type of the annular plate 212, the clamping component 77 includes a top plate 92 and a wider seat plate 93, wherein the structure of each plate can be matched with the bead 73 of the seal, and a plurality of 22 (Please read the note on the back first &#; fill out this page)

This paper size is applicable to the National Standard (CNS) A4 (210 X 297 mm) 476670 A7 B7 V. Description of the invention (π) Bolts 94 firmly connect the flat plates 92, 93 to the bead 73 for clamping. Similarly, the clamping assembly 77 must have an additional pressure plate 96 by which the plates 92 and 93 are deflected toward the bracket 18a. Therefore, after considering the content related to the previous technical configuration, the structure of the system 202 is simpler and the cost is lower. By fixing the connection of the bead 206 to the head 116, the cost of the system 202 is further reduced. Therefore, in the application example of the prior art configuration shown in FIG. 1 and FIG. 2, a ring-shaped clamping plate 90 is fixed to the head 16 by a bolt 91, where the opposing surfaces of the head 16 and the plate 90 are The structure can cooperate with the bead edge 72 of the sealing member 70 to fix the bead edge 72 between the opposite surfaces. Conversely, the configuration of the. System 202 only needs to form a radial outward opening groove 208 along the periphery of the head 116. Compared with the components used in the prior art arrangement, the manufacturing tolerances required for the bead 206 and the groove 208 and the manufacturing tolerances required for the bead 207 and the groove 209 are relatively loose. Preferably, the holding members 210 and 211 include clips of a type commonly referred to as a "worm drive hose clip". That is, the worm drive hose clamp is basically composed of a belt with a relatively non-stretchable material, wherein the belt will form a loop, which can be changed by the worm drive mode between the overlapping parts of the belt The size of the ring. The parts mentioned above can also be made in different sizes and materials. However, other metallic and non-metallic straps such as the commercially available trademark "Bandit" may be used. For example, a pipe clamp ring spring can also be used as a variation of the surrounding harness and non-metal restraint. The system 202 of the present invention further includes an integral part serving as the seal 204.

Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 476670 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention (correction) A continuous continuous skirt 214. The connection between the annular plate 212 and the bracket 118a is overlapped by the skirt portion 214, so that a seal can be provided between the annular plate and the contact surface of the bracket. It should be noted that the skirt portion 214 can be kept in a tightly sealed state by virtue of the elasticity of the constituent material of the seal 204. Thus, the skirt portion 214 can provide an effective seal to prevent fine particles and fluid from entering the sealed space below the annular plate 212. The intrusion of these foreign materials will accelerate the wear of the annular plate 212 and the bracket 118a. These foreign materials will also contaminate the lubricant in the crushing mechanism, reducing the service life of the low-pressure crusher components. Therefore, the skirt portion 214 can effectively extend the life of the crusher. In the arrangement illustrated in Figs. 3 and 4, there is a direct contact between metal and metal between the lower surface of the annular plate 212 and the opposite upper surface of the bracket 118a. By appropriately compressing the above surfaces of the spring 197 ', a suitable frictional engagement can be obtained. Thus, the frictional engagement can be used to restrict the rotation of the annular plate 212. Therefore, when the head 116 rotates without any material feed to the crushing action chamber 160 defined in the cup II4, 'because of the elastic member 204 The movement between the planes restricts the rotation of the head 116. However, the frictional engagement can cause the annular plate 212 to be pulled out by the member 204 to cause the annular plate 212 to be coupled with the head 116 when the head 116 is being rotated to crush a suitable material present in the action chamber 160. —Start turning. Graphite cast iron is known as a suitable material for forming the annular plate 212. In addition, the bracket 11Sa is composed of non-spheroidal graphite or ductile iron or other suitable iron-containing materials. However, if needed, a layer of material with a relatively high coefficient of friction can be provided on one or each of the ring plates 212 and the bracket 118a opposite 24 (please read the precautions on the back before filling this page) Binding-this paper The dimensions apply to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 476670 A7 B7_ V.
