Technical Field
[0001] This utility model relates to the field of power coal technology, specifically a coal desliming and sorting device for power coal. Background Technology
[0002] Thermal coal refers to coal used as a power source. In a narrow sense, it generally refers to coal used for thermal power generation. In a broader sense, any coal used for power generation, locomotive propulsion, boiler combustion, etc., to produce power, is considered thermal coal. The requirements for calorific value, volatile matter, and ash content of thermal coal are not as high as those for chemical coal (such as coking coal used in steelmaking). However, considering the economic benefits of power processes, thermal coal should also meet certain quality requirements. Coal is an important energy source in my country. During the formation of raw coal, various mineral impurities are mixed in, and during mining and transportation, rocks and other impurities from the roof and floor are inevitably mixed in. The main task of coal preparation is to remove impurities from raw coal and reduce its ash and sulfur content.
[0003] Extensive research revealed that the Chinese Utility Model Patent Publication No. CN221046212U discloses a coal desliming and sorting device, comprising a sorting box body and a feed inlet located at the top of the sorting box body for feeding. A servo motor is fixedly connected to the top of the sorting box body via a motor frame. A rotating shaft is provided at the output end of the servo motor, and a crushing roller for crushing coal is provided on the rotating shaft. A filter plate for screening is fixedly connected to the inner wall of the sorting box body. The filter plate has multiple first filter holes arranged in a circle. The rotating shaft is provided with a drive unit for moving the filter plate and a turning unit for turning the raw material. A rotating block is provided inside the drive unit, and a turning fan blade is provided inside the turning unit.
[0004] While the above-mentioned solution offers numerous advantages, the filter plates used in this device will experience clogging of the filter holes and surface wear after prolonged use, thus affecting the filtration efficiency of the filter plates. Therefore, they need to be replaced and cleaned regularly. However, the filter plates in this device are difficult to disassemble and assemble, which will affect the working efficiency of the coal desliming and sorting equipment. Utility Model Content
[0005] The purpose of this utility model is to provide a coal desliming and sorting device for power coal, so as to solve the problem that the maintenance and replacement of filter plates in the current coal desliming and sorting device for power coal is very troublesome.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a coal desliming and sorting device for power coal, comprising a housing, a sorting mechanism disposed within the housing, a bin disposed within the housing, the sorting mechanism disposed within the cavity of the bin, and an outlet and an inlet formed on one inner wall of the bin, a fixing groove formed on the inner side of the bin, a through-type mounting groove formed on one inner wall of the fixing groove, a filtering mechanism installed within the fixing groove, an mounting plate adapted to restrict the movement of the filtering mechanism within the cavity of the mounting groove, a non-circular first arc groove formed on one side of the mounting plate, a second arc groove formed on the inner wall of the first arc groove, and a limiting component for restricting the movement of the mounting plate within the cavity of the mounting groove disposed on one side of the housing.
[0007] Preferably, the filtration mechanism includes a fixing ring and a filter plate. The bottom of the filter plate is fixedly connected to a fixing rod arranged in a circumferential array.

[0008] Preferably, a retaining groove is formed on one side of the housing and opposite to the opening of the mounting groove, and a baffle is adapted to be installed in the retaining groove. The inner diameter of the mounting groove is smaller than the outer diameter of the baffle, and the baffle is fixedly connected to one side of the mounting plate.
[0009] Preferably, two track grooves are provided on one side of the housing, and the mounting groove is located between the two track grooves. A slider is slidably connected in the track groove, and a slide rod is fixedly connected between the two sliders. Two through threaded holes are provided on one side of the slide rod, and a threaded rod is threadedly connected in the threaded holes.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example: Figure 1 - Figure 6 As shown, this utility model provides a technical solution for a coal desliming and sorting equipment for power coal, including a box body 1, a sorting mechanism 2 disposed inside the box body 1, a bin 16 disposed inside the box body 1, the sorting mechanism 2 disposed inside the cavity of the bin 16, and a discharge port and a feed port formed on one side of the inner wall of the bin 16, a fixing groove 3 formed on the inner side of the bin 16, a through mounting groove 4 formed on one side of the inner wall of the fixing groove 3, a filter mechanism 5 installed in the fixing groove 3, an mounting plate 6 adapted to limit the movement of the filter mechanism 5 in the cavity of the fixing groove 3, a non-circular first arc groove opened on one side of the mounting plate 6, a second arc groove formed on the inner wall of the first arc groove, and a limiting component that limits the movement of the mounting plate 6 in the cavity of the mounting groove 4 disposed on one side of the box body 1;
[0026] When installing the filter mechanism 5, simply insert the filter mechanism 5 into the cavity area of the fixing groove 3 through the mounting groove 4, and then insert the mounting plate 6 into the cavity of the mounting groove 4 to install the filter mechanism 5. Otherwise, the filter mechanism 5 will be disassembled.
[0027] The specific structure of the sorting mechanism 2, as well as the connection method and usage method of the relevant structure, are all existing technologies. For a detailed description, please refer to the corresponding structure and components in the coal desliming and sorting equipment published in CN221046212U. This application will not elaborate further.
[0028] like Figure 5 and Figure 6As shown, the filter mechanism 5 includes a fixing ring 501 and a filter plate 502. The bottom of the filter plate 502 is fixedly connected to a fixing rod 503 arranged in a circular array. The fixing ring 501 has a fixing opening at the corresponding position of each fixing rod 503. The fixing rod 503 is slidably connected to the fixing opening. A spring is slidably sleeved on the outside of the fixing rod 503. The spring is located between the fixing ring 501 and the filter plate 502. One side of the fixing ring 501 and the filter plate 502 are in contact with one side of the mounting plate 6. One side of the fixing ring 501 is in contact with the second arc groove cavity, and one side of the filter plate 502 is in contact with the first arc groove cavity.
[0029] The fixing rod 503 is designed to stabilize the spring and the movement of the filter plate 502.
[0030] The outer wall of the filter plate 502 is in contact with the inner wall of the box 16. The outer diameter of the filter plate 502 is smaller than the outer diameter of the fixing ring 501. The fixing ring 501 is adapted to the cavity of the fixing groove 3. Simply insert the fixing ring 501 into the cavity of the fixing groove 3 and then rotate the mounting plate 6 to install the filter plate 502. The filter plate 502 uses a spring to slide up and down, thereby vibrating the filter plate 502 and facilitating the filtering of materials.
[0031] like Figure 1 - Figure 6 As shown, a retaining groove is formed on one side of the housing 1 and opposite to the groove opening of the mounting groove 4. A baffle 7 is adapted to fit in the retaining groove. The inner diameter of the mounting groove 4 is smaller than the outer diameter of the baffle 7. The baffle 7 is fixedly connected to one side of the mounting plate 6.
[0032] The baffle 7 is used to limit the mounting plate 6 from going too deep into the cavity of the mounting groove 4, so as to prevent the mounting plate 6 from going too deep into the mounting groove 4.
[0033] like Figure 4 - Figure 6 As shown, two track grooves 8 are opened on one side of the box body 1, and the mounting groove 4 is located between the two track grooves 8. A slider is slidably connected in the track groove 8, and a slide rod 9 is fixedly connected between the two sliders. Two through threaded holes are opened on one side of the slide rod 9, and a threaded rod 10 is threadedly connected in the threaded holes. A turntable 11 is rotatably connected to the movable end of the threaded rod 10, and the turntable 11 contacts one side of the mounting plate 6.
[0034] Slide the slide bar 9 using the track groove 8 so that the slide bar 9 is aligned with the baffle 7. Then rotate the threaded rod 10 so that the turntable 11 at the movable end of the threaded rod 10 abuts against the baffle 7. At this time, the mounting plate 6 in the mounting groove 4 can be fixed and stabilized. Conversely, it is convenient to loosen and remove the mounting plate 6.
[0035] like Figure 5 and Figure 6As shown, an inner ring 12 is fixedly connected to the bottom of the filter plate 502, and an outer ring 13 is fixedly connected to the top of the fixing ring 501. The outer ring 13 is slidably sleeved on the outside of the inner ring 12.
[0036] The outer wall of the inner ring 12 is in contact with the inner wall of the outer ring 13. By utilizing the cooperation between the inner ring 12 and the outer ring 13, material is prevented from falling into the installation area of the fixing rod 503.
[0037] like Figure 5 and Figure 6 As shown, the bottom end of the fixing rod 503 is provided with a threaded groove, and a bolt 14 is threadedly connected in the threaded groove. A hidden groove is formed at the bottom of the fixing port. The nut that is fixedly connected to the bottom end of the bolt 14 is located in the cavity of the hidden groove. The outer diameter of the nut is smaller than the inner diameter of the hidden groove, and the outer diameter of the nut is larger than the outer diameter of the fixing port.
[0038] The fixing rod 503 passes through the fixing opening and is then connected to the threaded groove at the bottom of the fixing rod 503 by bolt 14. This limits the fixing rod 503 and ensures that it can only slide within the cavity of the fixing opening and cannot leave the cavity, thus preventing the filter plate 502 from detaching from the contact with the fixing ring 501. The hidden groove can hide the nut and prevent the nut from affecting the installation and removal of the fixing ring 501.
[0039] like Figure 5 and Figure 6 As shown, an inclined ring is fixedly connected to the top of the filter plate 502, and multiple filter holes 15 arranged in a circular pattern are opened on the filter plate 502, with each filter hole 15 located inside the inclined ring.
[0040] The material is filtered using filter holes 15, and the inclined ring facilitates the material falling into the filter hole 15 area.
[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
