Description

Technical Field

[0001] The present invention relates to the technical field of forming machine tools, and particularly to a high-strength hydraulic press for coal processing. Background Art

[0002] When coal is processed, a molding hydraulic press is often required. It is a device used to press coal powder or particles into a specific shape. It uses the high pressure provided by the hydraulic system to compress the loose coal raw materials into high-density molded products, which are convenient for transportation, storage, and use.

[0003] In the prior art, the coal molding hydraulic press (as shown in Figure 13 ) mainly consists of a hydraulic system: including a hydraulic cylinder for providing high-pressure power; a mold for forming the specific shape of coal; a pressing head for directly applying pressure to the coal; a feeding box for feeding coal powder or particles into the mold cavity; a ejector plate for ejecting the molded coal; and a frame for supporting the entire device. The working principle is: the feeding box feeds coal powder or particles into the mold cavity, the hydraulic cylinder drives the pressing head to apply high pressure to the coal, causing it to be molded in the mold, and after molding, the ejector plate ejects the molded coal from the mold. By repeating the above steps, continuous production is achieved.

[0004] The deficiencies of the prior art are that when the feeding box feeds the coal powder raw materials into the mold cavity, the powder raw materials mainly fall into the mold cavity by gravity. Due to the limited volume of the mold cavity and the relatively loose distribution of the powder raw materials in the cavity in the initial state, the mass of the powder raw materials in the cavity is small. When the powder raw materials are pressed into a fixed volume, their density is low, resulting in a small specific gravity of the briquette, which increases the cost of subsequent transportation and storage. And if the volume of the briquette is reduced to increase its specific gravity, it will lead to a decrease in processing efficiency. Therefore, there is an urgent need for a high-strength hydraulic press for coal processing to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-strength hydraulic press for coal processing to solve the above deficiencies in the prior art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A high-strength hydraulic press for coal processing, including a hydraulic bed and a pressing head and a pressing mold arranged on the hydraulic bed. A plurality of cavities are opened in the pressing mold, and further includes: A feeding mechanism, which includes a feeding box placed on the top of the hydraulic bed for feeding the powder for coal processing into the cavity; A vibrating component arranged on the feeding box for vibrating the powder into the cavity; A driving frame arranged outside the feeding box for driving the feeding box to move to the top of the pressing mold; The driving frame is connected to the material distribution box through a clamping assembly. The driving frame includes two working strokes. The first working stroke drives the material distribution box to move to the top of the pressing mold and unlocks the clamping assembly. In the second working stroke, the driving frame is connected to the vibration assembly to drive the vibration assembly to vibrate and transport the powder into the cavity.

[0007] Preferably, it also includes a pressing hydraulic cylinder, whose output shaft is fixedly connected to the pressing head, and the bottom of the pressing head is provided with a pressing rod that cooperates with the cavity in the pressing mold.

[0008] Preferably, a material storage box and a material distribution multi-stage hydraulic cylinder are fixedly installed on the hydraulic bed, and the material distribution multi-stage hydraulic cylinder drives the material distribution mechanism to move. Positioning pins located at the front end of the pressing mold and the rear end of the material storage box are embedded on the top of the hydraulic bed.

[0009] Preferably, a material distribution bin is provided on the material distribution box, a vibrating assembly is inserted into the material distribution bin, and the vibrating assembly includes a transmission shaft and a vibrating rod transmission-connected to the transmission shaft.

[0010] Preferably, the material distribution mechanism further includes a transmission assembly, which is arranged at the ends of the plurality of vibrating assemblies and is used for transmission connection between the vibrating assemblies and the driving frame.

[0011] Preferably, the clamping assembly includes a clamping block and an elastic clamping seat. The clamping block is arranged on the inner side of the driving frame, and the elastic clamping seat is arranged at one end of the fabric box away from the pressing mold. The driving frame is clamped and connected to the fabric box via the clamping block and the elastic clamping seat.

[0012] Preferably, it also includes a connecting mechanism, a release rod, and a ejection plate. The ejection plate is clamped in the hydraulic bed, and the ejection plate is located directly below the pressing mold. The connecting mechanism includes a connecting rod, a connecting sleeve, and an elastic release assembly. The connecting rod is fixedly installed on the pressure head, and the connecting sleeve is fixedly installed on the ejection plate. When the pressure head moves down to the maximum stroke, the connecting rod and the connecting sleeve can be connected through the elastic release assembly.

[0013] Preferably, it also includes a release rod. When the ejector plate moves up to the maximum stroke, the release rod presses the elastic release assembly to disconnect the connecting rod from the connecting sleeve.

[0014] Preferably, it also includes a locking and releasing mechanism, which includes a positioning shaft fixedly installed on the top of the hydraulic bed, a locking rack fixedly connected to the top plate, and a one-way ratchet gear slidably mounted on the outside of the positioning shaft, the one-way ratchet gear and the locking rack are meshed with each other, and the locking rack can drive the one-way ratchet gear to rotate when it moves upward.

[0015] Preferably, the locking and releasing mechanism further includes a release dial plate which is fixedly connected to the fabric box. After the fabric box moves into place on top of the pressing die, the release dial plate can press against the one-way ratchet gear, causing the one-way ratchet gear to disconnect from the locking rack.

[0016] In the above technical solution, the beneficial effect of the present invention is that in the initial stage, the driving frame is clamped to the fabric box through the clamping assembly. After the fabric box is driven by the multi-stage fabric hydraulic cylinder to move to the top of the pressing die, the driving frame overcomes the clamping force of the clamping assembly and continues to move outside the fabric box. The driving frame can drive the vibrating assembly through the transmission assembly to vibrate and convey the powder material into the cavity, improving the density of the powder material in the initial stage. Furthermore, it can increase the specific gravity of the briquettes after coal powder processing, reduce the costs of subsequent transportation and storage, and improve the processing efficiency at the same time.

Detailed implementation manners

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0023] Please refer to Figures 1-12 , an embodiment of the present invention provides a technical solution: a high-strength hydraulic press for coal processing, including a hydraulic bed 1 and a pressing head 4 and a pressing die 5 arranged on the hydraulic bed 1. A plurality of cavities are provided in the pressing die 5, and further includes: A material distribution mechanism 8, which includes a material distribution box 81, is placed on the top of the hydraulic bed 1 and is used to deliver the powder for coal processing into the cavity; A vibrating assembly 83 is provided on the material distribution box 81 and is used to vibrate the powder into the mold cavity; The driving frame 85 is arranged outside the material distribution box 81 and is used to drive the material distribution box 81 to move to the top of the pressing mold 5; The driving frame 85 is connected to the material distribution box 81 through the clamping assembly 86. The driving frame 85 includes two working strokes. The first working stroke: it drives the material distribution box 81 to move to the top of the pressing mold 5 and unlocks the clamping assembly 86; the second working stroke, the driving frame 85 is connected to the vibration assembly 83, driving the vibration assembly 83 to vibrate and transport the powder into the cavity.

[0024] Specifically, the powder for coal processing is stored in the storage box 6, the top of the distribution box 81 is connected to the bottom of the storage box 6, and the powder in the storage box 6 falls into the several distribution bins 82 in the distribution box 81. The distribution multi-stage hydraulic cylinder 7 drives the driving frame 85 to move. In the initial stage, the driving frame 85 is connected to the distribution box 81 by the clamping block 861 and the elastic clamping seat 862. The driving frame 85 synchronously drives the distribution box 81 to move. When the distribution box 81 moves into place at the top of the pressing mold 5, the position of the distribution box 81 is limited by the positioning pin at the front end of the top of the hydraulic bed 1. The distribution multi-stage hydraulic cylinder 7 drives the driving frame 85 to overcome the clamping force of the elastic clamping seat 862 on the clamping block 861 and continue to move. The driving frame 85 drives the vibration assembly 83 to move through the transmission assembly 84, and vibrates the powder in the distribution bin 82 to the cavity.

[0025] Compared with the prior art, the embodiment of the present invention proposes a high-strength hydraulic press for coal processing. In the initial stage, the driving frame 85 is clamped with the material distribution box 81 through the clamping assembly 86. After the material distribution box 81 is driven by the material distribution multi-stage hydraulic cylinder 7 to move to the top of the pressing mold 5, the driving frame 85 overcomes the clamping force of the clamping assembly 86 and continues to move outside the material distribution box 81. The driving frame 85 can drive the vibration assembly 83 to vibrate and transport the powder into the cavity through the transmission assembly 84, thereby improving the compaction degree of the powder in the initial stage, thereby increasing the specific gravity of the coal powder blocks after processing, reducing the cost of subsequent transportation and storage, and improving the processing efficiency.

[0026] In an embodiment provided by the present invention, it also includes a pressing hydraulic cylinder 3, whose output shaft is fixedly connected to the pressing head 4, and the bottom of the pressing head 4 is provided with a pressing rod that cooperates with the cavity in the pressing mold 5. Specifically, a mounting frame 2 is fixedly installed in front of the top of the hydraulic bed 1, the pressing hydraulic cylinder 3 is fixed to the top of the mounting frame 2, and the pressing head 4 is movably installed on the mounting frame 2. The pressing hydraulic cylinder 3 drives the pressing head 4 to move and cooperate with the pressing mold 5, so as to realize the pressing operation of coal powder.

[0027] In another embodiment provided by the present invention, a storage bin 6 and a multi-stage hydraulic cylinder 7 for cloth feeding are fixedly installed on the hydraulic bed 1. The multi-stage hydraulic cylinder 7 for cloth feeding drives the cloth feeding mechanism 8 to move. A positioning pin is nested at the top of the hydraulic bed 1 at the front end of the pressing die 5 and the rear end of the storage bin 6. Specifically, the storage bin 6 is fixedly installed at the rear of the top of the hydraulic bed 1 and is used for storing the powder for coal processing. The bottom of the storage bin 6 is communicated with the top of the cloth feeding box 81, enabling the material to fall into the cloth feeding box 81; the multi-stage hydraulic cylinder 7 for cloth feeding is fixedly installed at the tail end of the hydraulic bed 1. The multi-stage hydraulic cylinder 7 for cloth feeding is a prior art and is commercially available, and is used to drive the cloth feeding mechanism 8 to reciprocate between the top of the pressing die 5 and the bottom of the storage bin 6; the positioning pin can limit the maximum forward and backward stroke of the cloth feeding box 81. When the multi-stage hydraulic cylinder 7 for cloth feeding pulls the cloth feeding box 81 back to the bottom of the storage bin 6 through the driving frame 85, the position of the cloth feeding box 81 is limited by the positioning pin at the rear end of the top of the hydraulic bed 1. The multi-stage hydraulic cylinder 7 for cloth feeding pulls the driving frame 85 to continue moving so that the clamping block 861 and the elastic clamping seat 862 are re-clamped.

[0028] As a preferred technical solution of the above embodiment, a cloth feeding bin 82 is provided on the cloth feeding box 81, and a vibrating component 83 is arranged through the cloth feeding bin 82. The vibrating component 83 includes a transmission shaft 832 and a vibrating rod 833 that is in transmission connection with the transmission shaft 832. Specifically, the cloth feeding bins 82 are evenly distributed in the cloth feeding box 81. The cloth feeding bin 82 is in the shape of an inverted frustum of a pyramid. The number of the cloth feeding bins 82 is the same as and corresponds one-to-one to the number of cavities in the pressing die 5. A set of vibrating components 83 cooperate with several cloth feeding bins 82 in the same column. The vibrating component 83 further includes an installation sleeve 831. The transmission shaft 832 is movably installed inside the installation sleeve 831, and the vibrating rod 833 is movably installed at the bottom of the installation sleeve 831. The cross-section of the part where the vibrating rod 833 and the installation sleeve 831 cooperate is rectangular, which can prevent the vibrating rod 833 from rotating; at the initial stage, the bottom of the vibrating rod 833 is flush with the bottom of the cloth feeding bin 82 to prevent the powder in the cloth feeding bin 82 from falling when the cloth feeding box 81 moves towards the pressing die 5. When the vibrating rod 833 moves upward, a gap is generated between the vibrating rod 833 and the inner wall of the cloth feeding bin 82, and the powder then slides to the bottom of the vibrating rod 833. Through the reciprocating up and down movement of the vibrating rod 833, the powder in the cloth feeding bin 82 is vibrated and conveyed into the cavity; the vibrating component 83 further includes a transmission connecting rod 834, which is arranged on the transmission shaft 832 and is used for the transmission connection between the transmission shaft 832 and the vibrating rod 833.

[0029] As a preferred technical solution of the above embodiments, the fabric mechanism 8 further includes a transmission assembly 84, which is arranged at the end of several vibration components 83 and is used to drive-connect the vibration components 83 with the driving frame 85. Specifically, the transmission assembly 84 includes several synchronous pulleys and a set of synchronous belts. The number of synchronous pulleys is the same as that of the vibration components 83, and the synchronous pulleys are fixedly sleeved at the ends of the transmission shafts 832. The synchronous belts are meshed and sleeved outside several synchronous pulleys. The transmission assembly 84 further includes a one-way ratchet component 842, a transmission gear 843 and a driving rack. The transmission gear 843 is connected to the set of synchronous pulleys farthest from the distance pressing die 5 through the one-way ratchet component 842. The transmission gear 843 can drive the synchronous transmission component 841 to rotate in one direction through the one-way ratchet component 842. The one-way ratchet component 842 is a prior art. After the driving frame 85 moves into place on the fabric box 81, at this time, the bottom of the vibration rod 833 returns to the state of being flush with the bottom of the fabric bin 82 again. The transmission gear 843 and the synchronous transmission component 841 are connected through the one-way ratchet component 842, and the one-way ratchet component 842 can only rotate in one direction. When the fabric multi-stage hydraulic cylinder 7 pulls the driving frame 85 to reset, the driving frame 85 does not drive the synchronous transmission component 841 and the vibration components 83 to rotate at this time, so that the vibration rod 833 can seal the bottom of the fabric bin 82 in the next working stage. The fabric mechanism 8 further includes a tail plate 87, which is arranged at one end of the fabric box 81 close to the fabric multi-stage hydraulic cylinder 7. During the process of the fabric box 81 separating from the bottom of the storage box 6, the tail plate 87 synchronously seals the bottom of the storage box 6.

[0030] As a preferred technical solution of the above embodiments, the clamping assembly 86 includes a clamping block 861 and an elastic clamping seat 862. The clamping block 861 is arranged inside the driving frame 85, and the elastic clamping seat 862 is arranged at one end of the fabric box 81 away from the pressing die 5. The driving frame 85 is clamped and connected to the fabric box 81 through the clamping block 861 and the elastic clamping seat 862. Specifically, the elastic clamping seat 862 is made of elastic metal and can realize clamping and detachment from the clamping block 861. The driving frame 85 is clamped and connected to the fabric box 81 through the clamping block 861 and the elastic clamping seat 862. After the driving frame 85 drives the fabric box 81 to the top of the pressing die 5, the fabric multi-stage hydraulic cylinder 7 drives the driving frame 85 to continue to move against the clamping force of the elastic clamping seat 862 on the clamping block 861. The driving frame 85 drives the transmission gear 843 to rotate through the driving rack. The clamping assembly 86 further includes a positioning side frame 863, which is fixedly installed on the fabric box 81 on the same side as the transmission assembly 84 and is clamped outside the driving frame 85 for positioning the driving frame 85 when it moves outside the fabric box 81.

[0031] In the prior art, for ejecting the compacted briquette, it is mostly to drive the ejector plate 12 to move upward by a driving mechanism to eject the briquette in the cavity. However, since the briquette is subjected to a large force during compaction, the briquette is prone to adhesion to the side wall of the cavity. Ejecting the briquette only from the bottom easily causes damage to the top of the briquette and affects the integrity of the briquette. In view of this, the following embodiments are proposed to solve this problem.

[0032] In another embodiment provided by the present invention, it further includes a connecting mechanism 9, a release rod 10, and an ejector plate 12. The ejector plate 12 is clamped in the hydraulic bed body 1 and is located directly below the pressing die 5. The connecting mechanism 9 includes a connecting plug rod 91, a connecting sleeve 92, and an elastic clamping and releasing assembly. The connecting plug rod 91 is fixedly installed on the pressing head 4, and the connecting sleeve 92 is fixedly installed on the ejector plate 12. When the pressing head 4 moves down to the maximum stroke, the connecting plug rod 91 and the connecting sleeve 92 can be connected through the elastic clamping and releasing assembly.

[0033] Specifically: The pressing hydraulic cylinder 3 drives the pressing head 4 to move down to cooperate with the pressing die 5 to press the powder in the cavity. When the pressing head 4 moves down to the maximum stroke, the connecting sleeve 92 is sleeved outside the tapered head at the end of the connecting plug rod 91. The locking tongue plate 94 cooperates with the tapered head through the inner inclined surface, moves outward against the elastic force of the compression spring 95, and finally makes the end of the locking tongue plate 94 close to the middle of the connecting sleeve 92 be clamped at the bottom of the tapered head, realizing the connection between the connecting sleeve 92 and the connecting plug rod 91. After the powder is pressed, the pressing head 4 drives the ejector plate 12 to move up synchronously through the connecting mechanism 9, and the briquette in the cavity is stripped by the clamping method of the pressing head 4 and the ejector plate 12 to ensure the integrity of the briquette. When the ejector plate 12 moves up to the maximum stroke, the top of the ejector plate 12 is flush with the top of the pressing die 5. At this time, the release rod 10 presses the outer inclined surface of the locking tongue plate 94 to disconnect the locking tongue plate 94 from the tapered head of the connecting plug rod 91, so that the pressing head 4 can continue to move up and reset. When the ejector plate 12 moves up, it drives the locking rack 111 to move synchronously. The upward movement of the locking rack 111 can drive the one-way ratchet gear 113 to rotate. After the ejector plate 12 moves up in place, since the one-way ratchet gear 113 can only rotate in one direction, the one-way ratchet gear 113 locks the positions of the locking rack 111 and the ejector plate 12. When the subsequent feeding box 81 feeds materials, when the feeding box 81 moves towards the top of the pressing die 5, the feeding box 81 can push the ejected briquette to discharge materials. After the feeding box 81 moves in place at the top of the pressing die 5, the release dial 115 on the feeding box 81 can drive the one-way ratchet gear 113 to move against the elastic force of the return spring 114, disconnecting the one-way ratchet gear 113 from the locking rack 111 and resetting the ejector plate 12.

[0034] As a preferred technical solution of the above embodiments, it further includes a release rod 10. When the ejector plate 12 moves upward to the maximum stroke, the release rod 10 presses against the elastic clamping and releasing assembly to disconnect the connecting plug rod 91 from the connecting sleeve 92. Specifically, a conical head is provided at the top of the connecting plug rod 91, which cooperates with the elastic clamping and releasing assembly to realize the connection between the connecting plug rod 91 and the connecting sleeve 92. The elastic clamping and releasing assembly includes a U-shaped bracket 93, a locking tongue plate 94 and a compression spring 95. The U-shaped bracket 93 is fixedly installed below the outer side of the connecting sleeve 92. The locking tongue plate 94 is movably installed in the U-shaped bracket 93. A compression spring 95 is movably sleeved on the locking tongue plate 94. The compression spring 95 can continuously apply an elastic force to the locking tongue plate 94, so that the locking tongue plate 94 has a tendency to move towards the middle of the connecting sleeve 92. An inclined surface matching the conical head is provided at one end of the locking tongue plate 94 close to the middle of the connecting sleeve 92, and an inclined surface matching the release rod 10 is provided at the top of the other end; a slot matching the release rod 10 is provided on the locking tongue plate 94. After the release rod 10 presses against the locking tongue plate 94 to expand it outwards, the release rod 10 can be inserted into the slot subsequently, so that the pressure head 4 can drive the connecting sleeve 92 to continuously move upward and reset.

[0035] As a preferred technical solution of the above embodiments, it further includes a locking and releasing mechanism 11. The locking and releasing mechanism 11 includes a positioning shaft 112 fixedly installed on the top of the hydraulic bed body 1, a locking rack 111 fixedly connected to the ejector plate 12, and a one-way ratchet gear 113 slidably sleeved outside the positioning shaft 112. The one-way ratchet gear 113 meshes with the locking rack 111, and when the locking rack 111 moves upward, it can drive the one-way ratchet gear 113 to rotate. Specifically, when the ejector plate 12 moves upward, it drives the locking rack 111 to move synchronously. When the locking rack 111 moves upward, it can drive the one-way ratchet gear 113 to rotate. After the ejector plate 12 moves upward in place, due to the one-way rotation of the one-way ratchet gear 113, the one-way ratchet gear 113 locks the positions of the locking rack 111 and the ejector plate 12.

[0036] As a preferred technical solution of the above embodiments, the locking and releasing mechanism 11 further includes a release dial plate 115, and the release dial plate 115 is fixedly connected to the fabric box 81. After the fabric box 81 moves in place on the top of the pressing die 5, the release dial plate 115 can press the one-way ratchet gear 113, so that the one-way ratchet gear 113 is disengaged from the locking rack 111. Specifically, when the fabric box 81 feeds materials, when the fabric box 81 moves towards the top of the pressing die 5, the fabric box 81 can push the ejected pressing block to discharge materials. After the fabric box 81 moves in place on the top of the pressing die 5, the release dial plate 115 on the fabric box 81 can drive the one-way ratchet gear 113 to move, so that the one-way ratchet gear 113 is disconnected from the locking rack 111, and the ejector plate 12 is reset; the locking and releasing mechanism 11 further includes a return spring 114, which is movably sleeved outside the positioning shaft 112 and can apply an elastic force to the one-way ratchet gear 113 to reset it. The one-way ratchet gear 113 is a prior art, and the one-way ratchet gear 113 and the positioning shaft 112 are connected by splines.

[0037] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
