Description
Technical Field
[0001] The utility model relates to a hammer crusher, belonging to the technical field of crusher equipment. Background Art
[0002] The working principle of the hammer crusher 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 crushes 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 the current hammer crusher is in use, it is easy for the material to be blocked on the mesh of the screen plate due to the humidity problem and the particle size problem of the material. After this happens, the material will accumulate on the screen plate, and the crushing output efficiency will be greatly reduced. 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.

[0025] The embodiment of the present invention provides a hammer crusher for the rapid replacement and cleaning of the screen plate, and can quickly replace the blocked screen plate when the equipment is running or temporarily stopped, thereby ensuring that the crushed materials of the equipment are discharged smoothly. The simple operation can be beneficial to improving the operating efficiency of the equipment. In order to realize the structural function of the device, the device is provided here, which includes a crushing barrel 1, wherein a crushing hammer assembly 2 is provided for rotation inside the crushing barrel 1, and a driving device 3 (a transmission mechanism such as a motor and a reducer) is provided on one side of the crushing barrel 1 for driving the crushing hammer assembly 2 to rotate. The top of the crushing barrel 1 is provided with a feed port. After the material enters the crushing barrel 1 from the top of the crushing barrel 1, it is impacted and broken by the high-speed rotating crushing hammer. In order to collect the material that meets the particle size requirements, a discharge pipe 4 is provided below the crushing barrel 1, and a screening component is provided at the feed port position of the discharge pipe 4 to screen products that meet the required particle size. In order to be able to deal with the blockage in time, the screening component is provided here, including a discharge plate 5, which is as shown in FIG. Figure 2 As shown, below the pulverizing cylinder 1 and at the position of the feed port of the discharge pipe 4, a sliding device is provided which penetrates the pulverizing cylinder 1, wherein discharge ports are respectively provided on both sides of the discharge plate 5, and each discharge port is installed with a sieve plate 6 which can form a position corresponding to the feed port of the discharge pipe 4. The sieve plate 6 is provided with mesh holes for normal screening of materials that meet the required particle size. In order to prevent the material from leaking from the fitting gap between the discharge plate 5 and the pulverizing cylinder 1, it is necessary to set the discharge plate 5 to fit closely with the upper sliding surface of the pulverizing cylinder 1. When the device is blocked during operation, it is mainly manifested as the blockage of the mesh of the sieve plate 6. At this time, the material output efficiency will be significantly reduced. At this time, by switching the position of the discharge plate 5, different sieve plates 6 can correspond to the position of the nozzle of the discharge pipe 4, so that the clean sieve plate 6 can be replaced in time when blocked to perform normal screening work. According to the setting method between the mechanisms, the sieve plate 6 can be directly replaced when the device is running, or the sieve plate 6 can be replaced during a short shutdown, so that the material can be screened and discharged smoothly without a complicated action process. At this time, the blocked sieve plate 6 can be cleaned and replaced when another sieve plate 6 is blocked. The operation is convenient and does not delay the production process.
[0026] A hammer crusher provided by an embodiment of the present invention takes into account that in order to allow the material to be better removed from the screen plate 6 by impact, the matching protrusion between the screen plate 6 and the inner wall of the crushing cylinder 1 should be reduced as much as possible. For this reason, as a preferred embodiment, the screen plate 6 can be set to a curved surface, wherein the curved surface shape of the screen plate 6 matches the inner wall shape of the crushing cylinder 1, and it is better to form a circular ring with the inner wall of the crushing cylinder 1 that does not interfere with each other.
[0027] The present invention provides a hammer crusher. In this embodiment, there are two screen plates 6. In order to enable the screen plate 6 to be accurately positioned at the nozzle of the discharge pipe 4 after movement, mounting plates 7 are provided on the crushing cylinder 1 and on both sides of the discharge pipe 4. Figure 2 as well as Figure 5 As shown, two mounting plates 7 are each provided with a locating pin 8, and a locating opening is provided on the discharge plate 5. The two locating pins 8 on either side can respectively engage within the corresponding locating openings, so that the corresponding sieve plate 6 can match the position of the discharge tube 4. To facilitate this action, or for the convenience of manual operation, the locating pins 8 can be set as elastic retractable pins. In this case, the locating pins 8 are fixed to the mounting plate 7, and the locating opening is set so that it does not pass through the discharge plate 5. The bottom surface of the locating opening and the top surface of the discharge plate 5 are in a circular arc transition. During operation, the discharge plate 5 is manually pushed to the other side, and the elastic retractable pins automatically retract until the elastic retractable pins on the other side automatically pop out, thus confirming that the sieve plate 6 has moved to a position that matches the discharge tube 4. This method requires pre-setting the locating openings and the installation position of the sieve plate 6. After positioning, it can greatly simplify manual work and is also more convenient for manual judgment of whether the sieve plate 6 is in the correct position. To facilitate pulling the discharge plate 5, handles 9 can be fixed on both sides of the discharge plate 5.
[0028] The hammer crusher provided by the embodiment of the present invention takes into account that in order to facilitate the cleaning of the replaced sieve plate 6, an annular recess can be provided on the discharge plate 5, and the sieve plate 6 can be fixed on the annular recess by bolts and other structures. The cleaning method can be blowing or water washing. However, considering that forward cleaning is still prone to clogging, it can be considered to turn the sieve plate 6 over and then wash it with water or blow it with air. At this time, the annular recess can be used to position the turned-over sieve plate 6 to prevent the sieve plate 6 from running during the cleaning process.
[0029] The hammer crusher provided by the present invention is designed to facilitate collection of pollutants from the sieve plate 6 during washing or blowing, which can directly affect the environment surrounding the equipment. Specifically, the wastewater tank 10 is provided with a connecting pipe 11 connected to the bottom of the sieve plate 6 where the discharge plate 5 is located. When the sieve plate 6 is cleaned, the pollutants can be directly collected into the wastewater tank 10 through the connecting pipe 11, thereby collecting the raw materials and avoiding pollution to the working environment. Considering that the cleaning positions of the sieve plates 6 on both sides are located on both sides of the crushing drum 1 after being pushed out, in order to save labor and avoid moving the wastewater tank 10, the connecting pipe 11 is preferably a hose, and a connector is provided at the top of the hose for connecting to the discharge plate 5. The hose 11 can be connected to different positions of the discharge plate 5 by bending, thereby avoiding the need to move the wastewater tank 10. To improve the extensibility or scalability of the connecting pipe 11, the connecting pipe can also be a telescopic hose.
[0030] The hammer crusher provided by the embodiment of the present invention can also include a columnar protective tube 13 in order to avoid the splashing of adhesive particles caused by high-pressure water washing or blowing. Specifically, an annular groove 12 is preferably provided on the top surface of the discharge plate 5 and on the outside of the annular concave platform. Figure 2 As shown, a columnar protective tube 13 is provided which can be inserted into the inner portion of the annular groove 12, as shown in FIG. Figure 1 As shown, the edge protection function of the columnar protective tube 13 can prevent the bonded particles from splashing to the surrounding side when cleaning the particles, thereby ensuring that they can fall within the range of the columnar protective tube 13, thereby ensuring the reliability of the cleaning and collection function.
[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.
