Technical Field
[0001] This utility model relates to the field of sorting equipment technology, and in particular to a barite sorting device that facilitates quick screen replacement. Background Technology
[0002] Barite, as an important non-metallic mineral raw material, is widely used in oil drilling, paint manufacturing, rubber filling, pharmaceuticals, and other fields. Different applications have strict requirements on its particle size. Paint production requires finer particles to ensure a uniform and dense coating. Barite screening equipment is the core of the processing flow, responsible for separating raw ore or semi-finished products into different grades according to particle size. This directly determines the quality of downstream products and production efficiency, and is a key link in meeting the differentiated needs of various industries.
[0003] Based on the above application scenarios, existing technology proposes a barite powder screening device (CN202421066529.9), including a screening box, a collection box movably connected to the lower inner side of the screening box, and feed hoppers symmetrically fixedly connected to the front and rear sides of the top of the screening box. A cover plate is hinged to the top of the feed hopper. A discharge ramp is fixedly installed in the middle of one side of the screening box, and limit side plates are symmetrically fixedly connected to the front and rear ends of the top of the discharge ramp. A discharge port is opened on the side of the screening box corresponding to the discharge ramp, and a filter screen is movably connected to the upper inner side of the screening box. This barite powder screening device, through the cooperation of the filter screen, side plates, vibrating motor, guide column, and spring, can achieve efficient filtration and screening of barite powder. The cylinder and baffle plate can seal and block the discharge port, ensuring that the barite powder on top of the filter screen is fully screened for a period of time before being discharged, thus improving the screening effect.
[0004] However, the aforementioned screening device suffers from significant inconvenience in screen replacement. Its filter screen lacks a dedicated quick-disassembly structure, requiring the removal of side plates, limiting components, and even temporary removal of components like the vibrating motor. This cumbersome and time-consuming process leads to production interruptions and severely impacts processing efficiency when production demands change and screens with different mesh sizes are needed to accommodate different barite particle sizes. Utility Model Content
[0005] To address the technical deficiencies in the background art, this utility model proposes a barite screening device that facilitates quick screen replacement. To further solve the aforementioned technical problems and meet practical needs, the specific technical solution is as follows: A barite sieving device with easy and quick screen replacement includes a sieving box. Inside the sieving box are symmetrically arranged pull-out and replaceable sieving components that are movably connected to the sieving box. The sieving components are arranged in a V-shape with symmetrical inclination within the sieving box. Below the sieving components is a crushing component connected to the inner wall of the sieving box. The sieving components include a screen frame, a screen disposed within the screen frame, and a vertically arranged pull-out side plate connected to one side wall of the screen frame. One side wall of the sieving box has a pull-out opening matching the size of the screen frame. Below the screen frame is a supporting crossbar. One end of the supporting crossbar is placed inside the pull-out opening and connected to the side wall of the sieving box, while the other end is connected to the inner wall of the sieving box on the side away from the pull-out opening. The supporting crossbar has a sliding groove extending along its length inside, and the bottom of the screen frame has a sliding strip that slides in cooperation with the sliding groove.
[0006] As a further technical solution of this utility model, an installation strip is provided on the side wall of the sieve frame away from the pull-out side plate, and an installation slot that cooperates with the installation strip is provided on the inner side wall of the sieve box.
[0007] As a further technical solution of this utility model, a handle is provided on the outer surface of the pull-out side plate, and a plurality of second threaded holes are symmetrically arranged on the outer surface of the pull-out side plate, with the second threaded holes being equally spaced and located on the upper and lower sides of the handle.
[0008] As a further technical solution of this utility model, the sieve box has a first threaded hole corresponding to the second threaded hole on the outer wall at the pull-out position, and a fixing screw for threaded connection is provided through the second threaded hole and the first threaded hole.
[0009] As a further technical solution of this utility model, the crushing assembly has a crushing seat installed inside the screening box, the crushing seat has a crushing chamber inside, the crushing chamber has crushing rollers symmetrically arranged inside, the feeding end of the crushing chamber is located below the downward inclined end of the screen, and the discharge end of the crushing chamber is connected to the bottom of the screening box.
[0010] As a further technical solution of this utility model, the rotating shafts at both ends of the crushing roller are rotatably connected to the side wall of the sieve box. The crushing roller is provided with a drive gear connected to one end of its rotating shaft outside the sieve box. The drive gears of the two crushing rollers mesh with each other, and a motor is connected to the rotating shaft on the side of the crushing roller connected to the drive gear.
[0011] As a further technical solution of this utility model, the top of the crushing seat is symmetrically equipped with a guide plate that is inclined in the opposite direction to the screen frame. The guide plate is located directly below the screen. The top of the screening box is equipped with a feeding hopper, and the feeding hopper is equipped with a separating plate. The two sides of the screening box are symmetrically equipped with side discharge ports. The upper end of the guide plate is located at the edge of the discharge end of the crushing chamber, and the lower end of the guide plate is connected to the side discharge port.
[0012] The beneficial effects of this utility model are as follows: The pull-out screening component design, with its bottom sliding strip and support crossbar groove, along with a handle and detachable fixing screws, eliminates the need to disassemble complex parts when replacing the screen. Simply unscrew the screws to pull it out, significantly reducing replacement time, preventing production interruptions, and effectively improving processing efficiency.

Detailed Implementation
[0019] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.
[0020] like Figures 1 to 5 As shown, this utility model provides a technical solution: a barite sieving device with a screen that facilitates quick screen replacement. It includes a sieving box 1, with sieving components 2 symmetrically arranged inside the sieving box 1. These components are removable and movably connected to the sieving box 1. The sieving components 2 are arranged in a V-shape, tilted symmetrically within the sieving box 1. Below the sieving components 2 is a crushing component 3 connected to the inner wall of the sieving box 1. The sieving component 2 includes a screen frame 22, a screen 21 disposed within the screen frame 22, and a vertically arranged pull-out screen connected to one side wall of the screen frame 22. Side plate 23, a pull-out opening 14 matching the size of the sieve frame 22 is provided on one side wall of the sieve box 1, a support crossbar 222 is provided below the sieve frame 22, one end of the support crossbar 222 is placed in the pull-out opening 14 and connected to the side wall of the sieve box 1, and the other end of the support crossbar 222 is connected to the inner wall of the sieve box 1 on the side away from the pull-out opening 14, a sliding groove 223 extending along the length direction is provided inside the support crossbar 222, and a sliding strip 221 that slides in cooperation with the sliding groove 223 is provided at the bottom of the sieve frame 22.
[0021] This utility model utilizes the sliding engagement between the bottom slide bar 221 of the sieve frame 22 of the sieve assembly 2 and the slide groove 223 of the support crossbar 222. The pull-out side plate 23 is provided with a handle 232, and its second threaded hole 231 is connected to the first threaded hole 15 at the pull-out port 14 of the sieve box 1 by a fixing screw 233. After unscrewing the fixing screw 233, the sieve assembly 2 can be pulled out by pulling the handle 232. There is no need to disassemble complex parts, and the sieve assembly 2 with different mesh screens 21 can be quickly replaced, which greatly shortens the replacement time, avoids production interruption, effectively improves processing efficiency, and solves the problem of inconvenient screen replacement in existing devices.
[0022] Meanwhile, the screening assembly 2 is arranged in a V-shape with symmetrical inclination. Combined with the distribution plate inside the feed hopper 11, it can evenly distribute barite to the screens 21 on both sides, extending the material screening path and improving screening adequacy. Coarse material that does not pass through the screen 21 falls into the feed end of the crushing chamber 311 of the crushing seat 31 due to the tilt of the screen frame 22. The motor 33 drives one of the crushing rollers 32 to rotate, and through the meshing drive gear 34, it drives the other crushing roller 32 to rotate synchronously, crushing the coarse material. After crushing, the material leaves the screening box 1 from the discharge end of the crushing chamber 311 and falls below the bottom of the screening box 1. Fine material that passes through the screen 21 falls onto the surface of the guide plate 13 and flows out from the side discharge port 12, achieving separation of coarse and fine materials and improving raw material utilization. Furthermore, the mounting strips 224 of the screen frame 22 are positioned in conjunction with the mounting slots 16 of the screening box 1 and reinforced by fixing screws 233, ensuring that the screening assembly 2 operates stably without shaking and guaranteeing the reliability of the equipment.
[0023] As one of the preferred embodiments of this utility model, such as Figures 2 to 4 As shown, the side wall of the sieve frame 22 away from the pull-out side plate 23 is provided with an installation strip 224, and the inner side wall of the sieve box 1 is provided with an installation slot 16 that cooperates with the installation strip 224.
[0024] The mounting strip 224 on the side wall of the screen frame 22 away from the pull-out side plate 23 is adapted to the mounting slot 16 on the inner side wall of the screening box 1. This allows for precise positioning and stable installation of the screening assembly 2. When the screen frame 22 is pushed into the screening box 1 along the slide groove 223 of the support crossbar 222 using the handle 232, the mounting strip 224 naturally embeds into the mounting slot 16. This prevents the screen frame 22 from shifting due to pushing and causing misalignment with the inner wall of the screening box 1, ensuring that the subsequent fixing screws 233 can be accurately aligned with the first threaded hole 15 and the second threaded hole 231. Simultaneously, the mating structure of the mounting strip 224 and the mounting slot 16 restricts the lateral sway of the screen frame 22 during equipment operation, forming a double fixation with the fixing screws 233. This further enhances the installation stability of the screening assembly 2, ensuring reliable screening processes without affecting the pull-out operation of the screen frame 22, and assists in the quick replacement of the screen 21.
[0025] As one of the preferred embodiments of this utility model, such as Figures 2 to 4 As shown, a handle 232 is provided on the outer surface of the pull-out side plate 23, and a plurality of second threaded holes 231 are symmetrically arranged on the outer surface of the pull-out side plate 23. The second threaded holes 231 are evenly spaced and located on the upper and lower sides of the handle 232.
[0026] Furthermore, in the above structure, the sieve box 1 has a first threaded hole 15 on its outer wall at the pull-out port 14 position, which corresponds to the second threaded hole 231. The second threaded hole 231 and the first threaded hole 15 are connected by a threaded fixing screw 233.
[0027] The handle 232 on the outer side of the pull-out side plate 23 allows operators to easily pull or push the screen frame 22 along the sliding groove 223 of the support crossbar 222 from the pull-out port 14 of the screening box 1, providing a convenient operating basis for the quick replacement of the screen 21. The second threaded holes 231, symmetrically distributed vertically and at equal intervals on the pull-out side plate 23, correspond to the first threaded holes 15 on the outer wall of the pull-out port 14 of the screening box 1. The two are connected by a through-threaded fixing screw 233, which firmly fixes the pull-out side plate 23 to the screening box 1, preventing the screening assembly 2 from loosening or shaking during equipment operation. When replacing the screen 21, simply unscrew the fixing screw 233 and pull the handle 232 to remove the screening assembly 2, without disassembling complex parts; during installation, simply align the screws with the holes and tighten them, greatly simplifying the operation and shortening the replacement time.
[0028] As one of the preferred embodiments of this utility model, such as Figure 1 As shown, the crushing component 3 has a crushing seat 31 installed inside the screening box 1. The crushing seat 31 has a crushing chamber 311 inside. The crushing chamber 311 has crushing rollers 32 symmetrically arranged inside. The feed end of the crushing chamber 311 is located below the downward inclined end of the screen 21. The discharge end of the crushing chamber 311 is connected to the bottom of the screening box 1.
[0029] In the crushing assembly 3, the crushing chamber 311 inside the crushing seat 31 provides space for crushing coarse materials and avoids material splashing during the crushing process. The symmetrically arranged crushing rollers 32 can crush coarse materials into fine materials that meet the particle size requirements through squeezing and grinding. The screening assembly 2 is V-shaped and inclined. Coarse materials that do not pass through the screen 21 will slide down along the inclined direction of the screen 21. The feed end of the crushing chamber 311 is located directly below the downward inclined end of the screen 21, which can receive these coarse materials. The discharge end of the crushing chamber 311 is connected to the bottom of the screening box 1. The material processed by the crushing rollers 32 can flow directly out from the bottom of the screening box 1, completing the secondary processing of the coarse materials.
[0030] As one of the preferred embodiments of this utility model, such as Figure 1 and Figure 5 As shown, the rotating shafts at both ends of the crushing roller 32 are rotatably connected to the side wall of the sieve box 1. The crushing roller 32 is provided with a drive gear 34 connected to one end of its rotating shaft outside the sieve box 1. The drive gears 34 of the two crushing rollers 32 mesh with each other. One of the crushing rollers 32 has a motor 33 connected to the rotating shaft on the side connected to the drive gear 34.
[0031] The rotating shafts at both ends of the crushing roller 32 are rotatably connected to the side wall of the sieve box 1, providing stable rotational support for the crushing roller 32. Outside the sieve box 1, the rotating shafts at one end of the two crushing rollers 32 are connected to drive gears 34, and the two drive gears 34 mesh with each other. The motor 33 is connected to the rotating shaft of one of the crushing rollers 32. The transmission of the drive gear 34 drives the other crushing roller 32 to rotate in the opposite direction through the meshing drive gear 34, thereby forming a crushing effect of squeezing and grinding on the coarse material falling into the crushing chamber 311.
[0032] As one of the preferred embodiments of this utility model, such as Figure 1 As shown, the top of the crushing base 31 is symmetrically equipped with a guide plate 13 that is inclined in the opposite direction to the screen frame 22. The guide plate 13 is located directly below the screen 21. The top of the sieving box 1 is provided with a feed hopper 11, and a dividing plate is provided inside the feed hopper. The sieving box 1 is symmetrically provided with side discharge ports 12 on both sides. The upper end of the guide plate 13 is placed at the edge of the discharge end of the crushing chamber 311, and the lower end of the guide plate 13 is connected to the side discharge port 12.
[0033] The guide plates 13 are symmetrically installed on the top of the crushing seat 31 and are inclined in the opposite direction to the screen frame 22 and located directly below the screen 21. They can receive the fine material after being screened by the screen 21. The inverted angle can guide the fine material to slide down and prevent the fine material from accumulating below the screen 21. The feed hopper 11 is installed on the top of the screening box 1. The feed plate inside the feed hopper 11 can divert the input barite raw material to the screens 21 that are inclined in a V shape on both sides, so as to avoid excessive load on one side of the screen 21 and ensure the uniformity of screening.
[0034] Fine materials can be discharged from the side outlets 12 on both sides of the screening box 1. The lower end of the guide plate 13 is connected to the side outlet 12, so that the fine materials can flow smoothly from the side outlet 12 along the guide plate 13 and effectively separate from the crushed materials discharged from the bottom of the screening box 1, thus completing the classification and collection of coarse and fine materials.
[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
