Abstract
Description
Technical Field
[0001] The utility model relates to an anti-clogging hammer crusher, belonging to the technical field of material crushing equipment. Background Art
[0002] The working principle of the hammer mill is that after the material enters the crushing chamber through the feed port, it is crushed by the impact of the rotating hammer head. The material is impacted by the high-speed rotating hammer head in the machine, and at the same time collides and breaks with the liner and screen plate in the crushing chamber, and is finally crushed into the required particle size and discharged through the sieve hole. When using the current hammer mill, due to the humidity and particle size of the material, it is easy for the material to be blocked on the mesh of the screen plate. When this happens, the material will accumulate on the screen plate, and the crushing output efficiency will drop significantly. In severe cases, it may even cause the equipment to shut down. At present, since the screen plate is usually installed inside the crushing barrel, when the screen plate needs to be cleaned, it is usually necessary to open the cover to clean the material and then clean the screen plate, which seriously delays the production process and affects production efficiency, and is also very inconvenient to operate. Summary of the Invention

[0024] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances. Example
[0025] The embodiment of the present invention provides an anti-clogging hammer mill, which is used for timely cleaning of the clogged mesh port of the hammer mill, and can conveniently replace the unblocked screen plate when a blockage occurs to ensure the normal operation of the mill, and can conveniently clean the screen plate replaced to other positions, which is convenient to operate and is conducive to ensuring the stable operation of the mill equipment. In order to realize the structural function of the equipment, the device is provided here, which includes a crushing barrel 1 and a crushing hammer mechanism 2 rotatably arranged inside the crushing barrel 1. A driving device for driving the crushing hammer mechanism 2 to rotate is also provided on one side of the crushing barrel 1. In order to realize the replacement of the particle filter part, thereby ensuring that the equipment can timely guarantee the output efficiency during the crushing process, a receiving tray 3 is rotatably provided at the lower position of the crushing barrel 1, such as Figure 1 and Figure 5 As shown, the side of the receiving tray 3 is provided with a plurality of receiving pipes passing through the receiving tray 3, and a sieve plate 4 is provided at the feed port position of each receiving pipe, and the sieve plate 4 is provided so as not to protrude from the outer circular arc surface where the receiving tray 3 is located. An opening is provided at the bottom of the crushing cylinder 1, and the receiving tray 3 is provided so as to drive the sieve plate 4 to correspond to the opening position at the bottom of the crushing cylinder 1 during rotation, so that the screened particulate material can pass through the sieve plate 4 and then be discharged from the corresponding receiving pipe, wherein the receiving tray 3 and the opening part of the crushing cylinder 1 are rotatably sealed to prevent the crushed particles from leaking out from the fitting gap between the equipment and the receiving tray 3. When the device is in use, the sieve plate 4 is used to screen and filter the particle size. When the material is clogged due to particle blockage or moisture, the receiving tray 3 can be rotated to rotate another sieve plate 4 fixed on it to the opening position of the crushing cylinder 1, so that the clogged sieve plate 4 can be replaced. Except for the position of the receiving pipe, the material will not be discharged from the receiving tray 3, so that the screening function can be normally realized after the sieve plate 4 is replaced to the appropriate position, thereby ensuring the output efficiency of the equipment. According to the special design of the solution, the sieve plate 4 can even be replaced without stopping the equipment, thereby improving the output efficiency of the product. The replaced sieve plate 4 can be manually cleaned and waited for standby.
[0026] The embodiment of the present invention provides an anti-clogging hammer mill, which specifically provides a rotating mechanism for driving the rotation of the receiving tray 3. In order to realize the function of the mechanism, the mechanism is provided here and also includes a stand 5, and bearing seats 6 are fixedly installed on both sides of the stand 5. Connecting shafts 7 are fixedly installed on both sides of the receiving tray 3. The two connecting shafts 7 on both sides are rotatably set on the corresponding bearing seats 6. The stand 5 is also provided with a motor 8 for driving the connecting shafts 7 to rotate. Although this setting method can determine the rotation position of the receiving tray 3, the height error when adjusting the sealing position when sealing with the crushing barrel 1 will be relatively large. Preferably, a plurality of adjustment feet can be provided at the bottom of the stand 5 to adjust the height and angle of the stand 5, so as to facilitate the coarse adjustment of the position of the receiving tray 3.
[0027] The present invention provides an anti-clogging hammer mill. In order to ensure that the collected fine powder particles flow down the pipeline, a plurality of receiving pipelines are provided, all of which pass through the center of the receiving tray 3, and each receiving pipeline is provided in a straight line. Figure 5 As shown, in order to prevent the product particles from flowing into other pipes, the number of pipes is preferably set to be relatively small. As a preferred embodiment, the receiving pipes are provided here, including a first receiving pipe 9 and a second receiving pipe 10. Specifically, the first receiving pipe 9 and the second receiving pipe 10 intersect vertically. In order to further reduce the deviation of the granular products from flowing into other pipes and making it inconvenient to collect them, a distribution port 11 is provided at the center of the receiving tray 3. Figure 5 As shown, the material distribution port 11 is arranged in a rectangular shape, wherein the first material receiving pipe 9 and the second material receiving pipe 10 are respectively connected to the four corner points of the rectangle where the material distribution port 11 is located. When the granular product flows down from one of the pipe ports, it will pass through the two sides of the rectangle for material guidance so that it can fall normally at the pipe port position of the discharge pipe, thereby reducing the deviation of the granular material and facilitating the collection of the material particles.
[0028] The embodiment of the present invention provides an anti-clogging hammer mill. In order to prevent one of the pipes from being ventilated during the material collection process and affecting the material collection action of the other pipe, a dust cover 12 can be installed on the stand 5. Figure 2 as well as Figure 5 As shown, the receiving tray 3 is rotatably arranged in the inner area of the dust cover 12. The dust cover 12 can block the first receiving pipe 9 or the second receiving pipe 10 separately during the rotation of the receiving tray 3, thereby preventing wind or other factors from affecting the normal receiving process. In order to ensure the normal collection of materials, a discharge pipe 13 for connecting the first receiving pipe 9 or the second receiving pipe 10 can be provided at the bottom of the dust cover 12. In order to ensure a good sealing action of the non-working discharge pipe, an elastic sealing layer for blocking the first receiving pipe 9 or the second receiving pipe 10 can also be provided inside the dust cover 12. The specific shape of the dust cover 12 can be referred to Figure 2 As shown, it is sufficient to achieve its functions. There are many other ways to facilitate installation, and we will not make too many restrictions here.
[0029] The embodiment of the present invention provides an anti-clogging hammer mill. In order to improve the sealing contact performance between the receiving tray 3 and the pulverizing drum 1, an auxiliary sealing block 15 can be provided at the opening position of the pulverizing drum 1. A circular arc surface matching the receiving tray 3 can be provided on the auxiliary sealing block 15, or a corresponding elastic sealing layer can be provided on the circular arc surface, so as to ensure good rotational sealing cooperation between the receiving tray 3 and the pulverizing drum 1. In order to detect the rotation position of the first receiving tube 9 or the second receiving tube 10 corresponding to the inside of the receiving tray 3, or to facilitate the direct rotation of the corresponding receiving tube to the specified position, a detection mechanism for detecting the rotation position of the receiving tray 3 can be provided on the auxiliary sealing block 15. Specifically, the detection mechanism can be set as a distance detection sensor 16, and a notch that can correspond to the distance detection sensor 16 can be provided on the receiving tray 3. The notch detects the distance change and thus infers whether the internal pipe is in the required position (the position of the preset notch needs to correspond to the position of the internal pipe).
[0030] The embodiment of the present invention provides an anti-clogging hammer mill. In order to facilitate the cleaning or replacement and installation of the sieve plate 4, countersunk grooves can be provided on the outer circumferential surface of the receiving tray 3. The positions of these countersunk grooves correspond to the corresponding receiving pipes. The sieve plate 4 is detachably installed in the countersunk grooves. The sieve plate 4 is arranged in a curved surface. The thickness of the sieve plate 4 is less than or equal to the height of the countersunk grooves. In the most ideal state, the sieve plate 4 should fit in with the outer arc surface of the receiving tray 3 to reduce the blockage and loss of particulate materials. It should be noted that the diameter of the receiving tray 3 should not be too small, otherwise it will cause the arc part to bulge too high inside the crushing barrel 1, which is easy to cause position conflict with the crushing mechanism. According to the actual design of the product, the distance between the edge of the crushing mechanism and the inner wall of the crushing barrel 1 should be reduced as much as possible, so that the diameter of the receiving tray 3 should be as large as possible within the ideal range.
[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
