Abstract
Description
Technical Field
[0001] This utility model relates to the field of recycled sand production, specifically a coal gangue recycled sand separation device. Background Technology
[0002] Coal gangue recycled sand is a sandy material obtained by processing industrial waste such as coal gangue through a series of processes. First, the coal gangue is crushed, breaking large pieces into suitable particle sizes, generally between 0.15mm and 5mm. Then, the crushed coal gangue is screened using screening equipment to separate particles of different sizes, obtaining a particle size range that meets the requirements for recycled sand. Next, a washing step is performed, rinsing the coal gangue particles with water to remove impurities, dust, and harmful substances such as sulfides, thereby improving the quality of the recycled sand. The washed coal gangue particles undergo dehydration treatment to remove excess water, achieving a suitable moisture content. Finally, the treated coal gangue particles are dried to reduce their moisture content to a specified range, enabling stable use in construction and other fields.
[0003] Current sand separation devices, as described in patent CN214262747U, include a separation mechanism and a base. The separation mechanism is located on the upper part of the base and includes a screen and tall and short columns. The lower end of the screen is provided with tall and short columns. The base includes a receiving box, a placement table, and a motor. The receiving box is provided on the upper surface of the base. The receiving box is installed at the lower end of the screen and on one side of the screen. The placement table is installed on one side of the base, and the motor is located on the upper part of the placement table.
[0004] Regarding the aforementioned technologies, the inventors believe that because the size of the sieve holes on the sieve plate is fixed, the particle size range of the sand that can be screened is fixed, which cannot meet the requirements for screening sand of different particle size ranges, resulting in poor applicability of the entire sand separation device. Utility Model Content
[0005] The purpose of this invention is to provide a coal gangue recycled sand separation device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A screening mechanism includes a screen plate with multiple rows of screen holes evenly opened at the bottom of the screen plate. The diameter of each row of screen holes is arranged in an increasing manner. Multiple extension blocks are evenly fixedly connected to both sides of the screen plate. A spring is fixedly connected to the bottom of each group of extension blocks. A support seat is fixedly connected to the bottom of each group of springs. A support beam is fixedly connected to the bottom of the support seats on both sides. A crossbeam is fixedly connected to the top of the screen plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] By adopting the above-mentioned structure, this utility model, through the cooperation of the sieve holes, the partition plates and the guide beam, and by gradually increasing the aperture of each row of sieve holes, can gradually screen out the sand inside the sieve plate in order of increasing particle size. The partition plates can separate the discharged sand according to different particle size ranges, so that the partition plates can be slid to separate the sand screened by the sieve holes according to different particle size ranges, thereby effectively improving the applicability of the entire separation device.

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0023] Please see Figure 1-4 A coal gangue recycled sand separation device includes a screening mechanism 1, which includes a screen plate 101. Multiple rows of screen holes 102 are uniformly opened at the bottom of the screen plate 101. The screen holes 102 are used to screen and separate the sand inside the screen plate 101. The diameter of each row of screen holes 102 increases progressively, allowing the sand to be screened out according to progressively larger particle sizes. Multiple extension blocks 105 are uniformly fixedly connected to both sides of the screen plate 101. Each set of extension blocks 105 has a reinforcing rib plate 106 symmetrically fixedly connected to its top. Each set of reinforcing rib plates 106 is fixedly connected to the screen plate 101, further connecting and fixing the extension blocks 105 to the screen plate 101, thereby improving the connection stability between the extension blocks 105 and the screen plate 101.
[0024] Each set of extension blocks 105 is fixedly connected to a spring 107 at its bottom, and each set of springs 107 is fixedly connected to a support base 108 at its bottom. The extension blocks 105, springs 107, and support bases 108 provide support for the screen plate 101. Support beams 109 are fixedly connected to the bottom of the support bases 108 on both sides, providing support for the support bases 108. A crossbeam 103 is fixedly connected to the top of the screen plate 101, and a vibration motor 104 is fixedly connected to the top of the crossbeam 103. The vibration motor 104 is used to drive the crossbeam 103 and the screen plate 101 to vibrate during startup, thereby improving the screening efficiency of sand.
[0025] The separation mechanism 2 includes guide beams 201 symmetrically fixedly connected to opposite sides of the two support seats 108. Multiple partition plates 204 are uniformly slidably connected between the two sets of guide beams 201. The partition plates 204 are used to separate the sand screened by the sieve holes 102, thereby separating sand of different particle size ranges. A guide plate 205 is symmetrically fixedly connected to the bottom of each set of partition plates 204. The guide plate 205 is used to guide the sand flow, thereby separating sand of adjacent particle size ranges more thoroughly. A connecting rod 206 is fixedly connected between adjacent guide plates 205. Guide grooves 202 are provided on opposite sides of the two sets of guide beams 201. Guide blocks 203 adapted to the guide grooves 202 are fixedly connected to both sides of each set of partition plates 204. The guide grooves 202 and guide blocks 203 are used to guide the movement of the partition plates 204. Both sets of support beams 109 are symmetrically threaded with adjusting screws 209. Abutment beams 208 are rotatably connected to the opposite sides of the adjusting screws 209. The two sets of abutment beams 208 abut against each set of partition plates 204. The adjusting screws 209 are designed to move the abutment beams 208 during rotation, thus restricting the sliding of the partition plates 204 when the abutment beams 208 abut against them, thereby positioning the partition plates 204. Grooves 207 are formed on the opposite sides of both sets of support beams 109. The grooves 207 are adapted to the abutment beams 208 and are designed to accommodate the abutment beams 208, allowing the abutment beams 208 to move into the grooves 207 and push away any sand on top of them.
[0026] In this embodiment, the vibration motor 104 is existing technology and will not be described in detail here.
[0027] In use, the vibration motor 104 is started, which drives the crossbeam 103 and the screen holes 102 to vibrate. Then, the sand to be screened is poured in from one side of the screen plate 101. After the sand is poured in, it can be gradually screened by each row of screen holes 102 under the vibration of the screen plate 101. As the aperture of each row of screen holes 102 gradually increases, the particle size of the screened sand gradually increases. Then, the position of each set of partition plates 204 can be slid as needed to separate and discharge the sand screened by the screen holes 102 according to the required particle size range, thereby effectively improving the applicability of the entire sand separation device.
[0028] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
