[0041] like Figure 1-Figure 5As shown, this embodiment provides a coal drying device, which includes a screening assembly 100, an aggregate container 200 and a drying assembly 300.

[0042] like Figure 1 and Figure 2 As shown, the screening assembly 100 includes a box body 101 and a filter screen 120. The filter screen 120 is arranged in the box body 101 and divides the space in the box body 101 into a first space 130 and a second space 140. The first space 130 is located on the upper side of the filter screen 120, and the second space 140 is located on the lower side of the filter screen 120. The box body 101 is provided with a feed port 115 connected to the first space 130, and a first discharge port 116 is provided on the box wall of the first space 130, and a second discharge port 117 is provided on the box wall of the second space 140. The aggregate container 200 is provided with a first aggregate trough 201 and a second aggregate trough 202 that are independent of each other. The first aggregate trough 201 is used to receive the incoming material from the first discharge port 116, and the second aggregate trough 202 is used to receive the incoming material from the second discharge port 117. The drying assembly 300 is used to dry the coal in the first aggregate trough 201 and the second aggregate trough 202.

[0043] In the coal drying equipment provided in this embodiment, the screening component 100 divides the space in the box 101 into a first space 130 and a second space 140 through a filter 120. Coal of different particle sizes can enter the first space 130 from the feed port 115, and then be screened by the filter 120. The coal that meets the particle size requirements enters the second space 140. This design realizes the preliminary screening of coal, provides a basis for subsequent different treatments, and improves the pertinence and efficiency of coal treatment. The aggregate container 200 is provided with a first aggregate trough 201 and a second aggregate trough 202 that are independent of each other, respectively receiving the incoming materials from the first discharge port 116 and the second discharge port 117, and classifying and collecting the sieved coal, so that different types of coal can be separated, and then the subsequent drying process is carried out to avoid confusion, which is helpful to improve the drying effect and product quality. The drying component 300 dries the particle size classified coal in the first aggregate trough 201 and the second aggregate trough 202 to achieve coal drying.

[0044] In some embodiments, the coal drying equipment further includes a first fixing frame 170 , and the box body 101 is fixedly disposed on the upper end of the first fixing frame 170 .

[0045] like Figure 1As shown, optionally, the aggregate container 200 includes a trough-type aggregate box 203 and a partition 204, the partition 204 is arranged in the trough-type aggregate box 203, and divides the space in the trough-type aggregate box 203 into a first aggregate trough 201 and a second aggregate trough 202, both of which are open upward, and the screening assembly 100 also includes a first material guide 118 and a second material guide 119, the feed end of the first material guide 118 is connected to the first material outlet 116, the feed end of the second material guide 119 is connected to the second material outlet 117, the discharge end of the first material guide 118 is located above the first aggregate trough 201, and the discharge end of the second material guide 119 is located above the second aggregate trough 202. The aggregate container 200 adopts the design of the trough-type aggregate box 203 and the partition 204, and has a simple and reasonable structure, which is convenient for manufacture and installation. The partition 204 separates the trough-type aggregate box 203 into the first aggregate trough 201 and the second aggregate trough 202, ensuring the independence of the aggregates. At the same time, the first guide 118 and the second guide 119 can accurately guide the screened coal to the corresponding aggregate trough, with a simple structure, convenient for continuous operation, ensuring the continuity of screening and aggregation, and improving production.

[0046] In some embodiments, the first guide member 118 and the second guide member 119 extend obliquely downward from their respective feed ports 115 to their respective discharge ports, so as to facilitate the output of the coal under gravity. The first guide member 118 and the second guide member 119 can be guide pipes or guide troughs.

[0047] Optionally, the bottom wall of the trough-type material collection box 203 is a heat-conducting wall, and the drying assembly 300 is arranged below the heat-conducting wall. In other words, the first material guide 118 and the second material guide 119 are at the top, and the drying assembly 300 is at the bottom, and they are arranged on both sides of the trough-type material collection box 203 respectively. The structure is compact and the spatial layout is more reasonable, and efficient classification, collection and drying of coal are achieved in a limited space. The heat-conducting wall can transfer heat more directly to the coal in the material collection trough, improve the heat transfer efficiency, reduce heat loss, thereby accelerating the drying speed of the coal, improving the energy utilization efficiency of the drying assembly 300, and reducing energy consumption.

[0048] In some embodiments, the trough-type aggregate box 203 is a sheet iron box, which has good thermal conductivity.

[0049] like Figure 1As shown, optionally, the coal drying equipment also includes a support structure 400 and a reciprocating drive member 500, the support structure 400 is arranged on both sides of the trough-type aggregate box 203 in the first direction, the trough-type aggregate box 203 is movably mounted on the support structure 400, the reciprocating drive member 500 is connected to the trough-type aggregate box 203, and the reciprocating drive member 500 can reciprocate and extend along the second direction, and the first direction is perpendicular to the second direction. The trough-type aggregate box 203 is movably mounted on the support structure 400, and the reciprocating drive member 500 drives the trough-type aggregate box 203 to reciprocate and extend along the second direction, so that the coal in the trough-type aggregate box 203 can be continuously turned over during the drying process. This not only increases the contact opportunity between the coal and the heat-conducting wall, further improves the drying efficiency, but also avoids the problem of excessive or uneven local drying of the coal due to long-term static state, thereby improving the drying quality.

[0050] like Figure 1 As shown, in some embodiments, the reciprocating drive member 500 is disposed on a side of the trough-type aggregate box 203 away from the box body 101 in the second direction. Optionally, the reciprocating drive member 500 includes a support seat 501 and a telescopic push rod 502, the support seat 501 is disposed on a side of the trough-type aggregate box 203 away from the box body 101 in the second direction, the telescopic push rod 502 is disposed on the support seat 501, and the telescopic push rod 502 extends along the second direction. When the telescopic push rod 502 is started, the telescopic push rod 502 pushes the trough-type aggregate box 203 to swing left and right above the drying assembly 300, so that the coal inside the trough-type aggregate box 203 is evenly heated.

[0051] like Figure 1 As shown, optionally, the support structure 400 includes at least three support columns 401, each support column 401 is provided with a groove 402, and each support column 401 is respectively arranged on both sides of the trough-type aggregate box 203 in the first direction, and the outer walls of the trough-type aggregate box 203 on both sides in the first direction are provided with protrusions 205 corresponding to the grooves 402, and the protrusions 205 are loosely matched in the grooves 402. The support structure 400 is loosely matched with the protrusions 205 on the outer wall of the trough-type aggregate box 203 through the grooves 402 on at least three support columns 401, and the loose matching provides a certain activity space, and provides stable support for the trough-type aggregate box 203, ensuring that the trough-type aggregate box 203 is limited to move within a certain range during the movement of the reciprocating drive 500, thereby ensuring the stability of the operation of the equipment. In some embodiments, there are four support columns 401, of which two support columns 401 are arranged on one side of the trough-type aggregate box 203, and the other two are arranged on the other side of the trough-type aggregate box 203.

[0052] like Figure 1As shown, optionally, the trough-type aggregate box 203 is arranged on one side of the box body 101 in the horizontal direction, and the first discharge port 116 and the second discharge port 117 are both arranged on the side wall of the box body 101 close to the trough-type aggregate box 203. The trough-type aggregate box 203 is arranged on one side of the box body 101 in the horizontal direction, and the first discharge port 116 and the second discharge port 117 are arranged on the side wall close to the trough-type aggregate box 203. This layout allows the screened coal to enter the first aggregate trough 201 and the second aggregate trough 202 in the shortest path, reducing the coal transportation distance, improving the coal transmission efficiency, and making the structure of the entire equipment more compact, reducing space occupancy, and saving equipment costs. In this embodiment, the screening assembly 100, the trough-type aggregate box 203 and the reciprocating drive member 500 are arranged in sequence along the second direction.

[0053] like Figure 4 and Figure 5 As shown, optionally, the box body 101 includes a main box 111 and a box door 112, the main box 111 is arranged on one side of the trough-type aggregate box 203 in the horizontal direction, the main box 111 is provided with a box opening on the side wall away from the trough-type aggregate box 203 in the horizontal direction, and the box door 112 can be opened and closed at the box opening, and a first locking member 113 is provided on the box door 112, and a second locking member 114 is provided on the main box 111, and the first locking member 113 can be locked with the second locking member 114. The box door 112 is arranged on the side facing away from the trough-type aggregate box 203, and the structure is compact and reasonable. The box door 112 can be opened and closed, which is convenient for cleaning and maintenance of the inside of the main box 111. After the equipment has been used for a period of time, opening the box door 112 can easily clean the remaining coal in the box body 101, check whether the filter 120 and other components are damaged, and ensure the normal operation of the equipment. The first locking member 113 and the second locking member 114 ensure that the box door 112 is tightly locked with the main box 111 when closed, so as to facilitate locking or unlocking the box door 112 .

[0054] In some embodiments, a pull ring 102 is provided on the box body 101 to facilitate the opening and closing operation. By pulling the pull ring 102, the box door 112 is easy to open or close, and the structure inside the box body 101 is easy to install and disassemble.

[0055] In some embodiments, the first locking member 113 includes a first ring, and the second locking member 114 includes a second ring and an insertion rod. The first ring and the second ring are arranged opposite to each other along the length direction of the insertion rod. The insertion rod is inserted into the first ring and the second ring at the same time to achieve locking. The insertion rod is pulled out of the first ring to achieve unlocking.

[0056] like Figure 1 and Figure 2As shown, optionally, the screening assembly 100 further includes a receiving platform 150 and a pushing assembly 160. The receiving platform 150 is located below the filter screen 120. The second space 140 is enclosed between the box body 101, the filter screen 120 and the receiving platform 150. The pushing assembly 160 can be reciprocatingly slidably arranged on the receiving platform 150. The second discharge port 117 is arranged on the side wall of the box body 101 in the sliding direction of the pushing assembly 160. The receiving platform 150 is located below the filter screen 120, and encloses the second space 140 with the box body 101 and the filter screen 120, providing a temporary storage platform for the coal in the second space 140. The pushing assembly 160 can reciprocatingly slide and can push the coal on the receiving platform 150 to the second discharge port 117, thereby realizing the effective collection and transportation of the coal in the second space 140, avoiding the accumulation of coal in the second space 140, and improving the smoothness of the screening process.

[0057] In some embodiments, the pushing assembly 160 reciprocates and telescopes in a straight line direction, and the second discharge port 117 is arranged on the box wall of the box body 101 on one side in the pushing direction. Further optionally, in the telescopic direction perpendicular to the pushing assembly 160, the two ends of the upper end surface of the receiving platform 150 are respectively protruded upward with a first baffle 151 and a second baffle 152, and the first baffle 151 and the second baffle 152 realize the delivery of the falling coal to the upper end surface of the receiving platform 150.

[0058] like Figure 2 and Figure 3 As shown, optionally, the pusher assembly 160 includes a pusher plate 161, which can be reciprocatingly slidably arranged on the surface of the receiving platform 150, and one of the pusher plate 161 and the receiving platform 150 is provided with a guide portion 162, and the other is provided with a guide groove 164, and the guide portion 162 is slidably arranged in the guide groove 164. The pusher plate 161 and the receiving platform 150 cooperate with the guide portion 162 and the guide groove 164 to provide precise guidance for the reciprocating sliding of the pusher plate 161, ensure that the pusher plate 161 will not deviate during the sliding process, stably push the coal to the second discharge port 117, and improve the accuracy and reliability of the pushing process. Moreover, the cooperation between the guide groove 164 and the guide portion 162 is conducive to reducing the sliding resistance. In some embodiments, the guide portion 162 can be a guide rib or a slider.

[0059] like Figure 2 As shown, in some embodiments, the driving member 163 of the pushing assembly 160 can be an electric push rod. The electric push rod is connected to the pushing plate 161 by transmission, and the electric push rod can be set on the box wall of the box body 101. The number of electric push rods is not limited. Optionally, two electric push rods are provided, both of which are connected to the pushing plate 161 by transmission. The driving member 163 pushes the coal to the second discharge port 117, and the coal falls into the second collecting tank 202 from the second discharge port 117.

[0060] like Figure 1 and Figure 2 As shown, optionally, a feed port 115 is provided at the upper end of the box 101, the periphery of the filter screen 120 is connected to the inner peripheral wall of the box 101, the space in the box 101 between the filter screen 120 and the feed port 115 is the first space 130, the first discharge port 116 is arranged on the side wall of the box 101 in the first space 130, the filter screen 120 is inclined from top to bottom, and the lower end extends to the first discharge port 116. The feed port 115 is arranged at the upper end of the box 101, and the filter screen 120 is connected to the inner peripheral wall of the box 101. This layout makes full use of the space of the box 101, making the flow and screening process of the coal in the box 101 more reasonable and orderly, and helping to improve the working efficiency of the entire screening assembly 100. The filter screen 120 is inclined from top to bottom and the lower end extends to the first discharge port 116, which is conducive to the natural sliding of the coal under the action of gravity, accelerating the speed of the coal passing through the filter screen 120, and improving the screening efficiency. At the same time, this inclined design can make the coal that does not meet the particle size of the filter 120 be discharged smoothly from the first discharge port 116, avoid the coal from accumulating at the filter 120, and ensure the smooth screening process. The coal is screened by the screen, so that the coal of different sizes can be screened, and the screened coal passes through the corresponding first discharge port 116 and the second discharge port 117, so that the large coal and the small coal are separated.

[0061] When the embodiment of the present invention is working, when it is necessary to dry the coal, the coal is first passed through the screen of the grouping assembly into the interior of the box 101, and the smaller coal falls into the second space 140 through the screen and falls on the upper end surface of the receiving platform 150, and is prevented from falling on the bottom of the box 101 by the first baffle 151 and the second baffle 152. The driving member 163 of the pushing assembly 160 is started to push the pushing plate 161, and the smaller coal passes through the second discharge port 117. , enters the second aggregate trough 202 through the second guide member 119, and the larger coal passes through the first discharge port 116 and the first guide member 118 and enters the first aggregate trough 201, and the drying assembly 300 and the reciprocating drive member 500 are started. The reciprocating drive member 500 pushes the trough-type aggregate box 203 to move back and forth, and the trough-type aggregate box 203 swings on the supporting structure 400, so that the coal swings inside the first aggregate trough 201 and the second aggregate trough 202, so that the coal is heated more evenly.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
