Description

Technical Field

[0001] This utility model relates to the field of lime screening technology, and more specifically, to a lime particle screening device. Background Technology

[0002] Different industrial applications have specific requirements for the particle size of lime, necessitating the use of screening devices to screen the lime particles to meet the application requirements.

[0003] There are many existing technologies for screening equipment, such as:

[0004] Chinese patent application CN209406822U discloses a metallurgical lime screening and recovery device, including a support frame, a motor, and a reducer. A screen cylinder frame is welded to the inner side of the support frame, and a screen cylinder is embedded within the inner side of the screen cylinder frame. A feed hopper is located on the left side of the screen cylinder and welded to the top of the support frame. The reducer is located on the right side of the screen cylinder, and the motor is located on the right side of the reducer. A discharge hopper is located on the inner side of the screen cylinder frame, and a discharge assembly is located at the bottom of the discharge hopper and welded to the lower surface of the screen cylinder frame. A groove is provided on the outer surface of the front end of the support frame, and a support ring is embedded within the groove. Gauze is adhered to the right side of the support ring, and a fixing assembly is located on the left side of the support ring. The advantages of this invention are that it facilitates maintenance while reducing dust emission, facilitates cleaning of the screen cylinder's inner mesh, and allows for easy adjustment of the discharge port position and size.

[0005] In existing screening devices, lime granules are typically poured into the equipment and screened by a screening mechanism. However, during the screening process, the screening equipment is usually designed for materials within a specific particle size range. Particles that are significantly too large and do not meet the particle size requirements are prone to getting stuck in the screen. Furthermore, under the high-frequency vibration of the vibrating motor, large particles can easily cause the mesh to deform due to impact, shortening the service life of the screen. In view of this, we propose a lime granule screening device. Utility Model Content

[0006] The purpose of this utility model is to solve the above-mentioned shortcomings and provide a lime particle screening device to solve the problem that obviously oversized particles that do not meet the particle size requirements enter the screening mechanism, easily clogging the screen, and that large particles are easily deformed by impact under the high-frequency vibration of the vibrating motor.

[0007] To achieve the above objectives, this utility model provides a lime particle screening device, including a screening equipment body, a pretreatment box, and a pretreatment component. The pretreatment box is fixedly connected to one side of the top of the screening equipment body, and the pretreatment component is arranged in the inner cavity of the pretreatment box. The pretreatment component includes a selection component arranged near the bottom of the inner cavity of the pretreatment box. The selection component is inclined in the inner cavity of the pretreatment box, and an adjustment component is arranged at the bottom of the selection component. A crushing component is arranged on one side of the inner cavity of the pretreatment box, and the crushing component is located above the lower side of the selection component.

[0008] The beneficial effect of adopting the above-mentioned further solution is that after the lime particles are poured into the pretreatment box, obviously excessively large particles are intercepted, preventing them from entering the screening mechanism and easily causing the screen to be deformed by impact, thus shortening the service life of the screen.

[0009] As a further improvement to this technical solution, the screening equipment body includes a shell, a screening component is provided on the shell, a vibration motor is provided on the shell, the pretreatment box is fixedly installed on one side of the top of the shell, a material discharge port is provided at the bottom of the inner cavity of the pretreatment box, and a material outlet is provided on the lower side of the shell away from the pretreatment box.

[0010] As a further improvement to this technical solution, a feed inlet is fixedly provided on the top of the pretreatment box, and a communicating hole is opened at the connection between the feed inlet and the pretreatment box.

[0011] As a further improvement to this technical solution, the sorting component includes a sorting plate fixedly disposed at the bottom of the pretreatment chamber cavity. The sorting plate is inclined at the bottom of the pretreatment chamber cavity, and a plurality of material dropping holes are evenly opened on the surface of the sorting plate.

[0012] The advantage of adopting the above-mentioned further solution is that it guides the selected particles closer to the crushing component, making it easier to crush them so that they meet the screening standards and can be subjected to subsequent screening processing.

[0013] As a further improvement to this technical solution, the adjustment component includes a slider that is slidably disposed at the bottom of the selection plate, and multiple sliders are evenly disposed thereon. An adjustment plate is fixedly disposed at the bottom of the slider, and multiple grooves that are adapted to the sliders are opened at the bottom of the selection plate.

[0014] As a further improvement to this technical solution, the crushing component includes a rotating rod rotatably disposed in the inner cavity of the pretreatment box near the side with a lower height from the sorting plate. The rotating rod has blades fixedly disposed on its surface, and multiple sets of blades are evenly disposed on the surface of the rotating rod. A motor is disposed on one side of the pretreatment box, and the output end of the motor is fixedly connected to one end of the rotating rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this lime particle screening device, a sorting component intercepts particles that are obviously too large or do not meet the particle size requirements in the pretreatment box, thereby reducing the load on subsequent screening equipment. The intercepted non-compliant particles are then rolled by gravity to the crushing component for crushing. Once they meet the standards of the sorting component, they enter the screening equipment for screening. This conveniently crushes particles that do not meet the screening standards, avoiding the need to transfer them to a dedicated crushing mechanism for further crushing and then re-feeding them to the screening equipment itself. This improves work efficiency. By adjusting the components to change the interception specifications, the sorting process can be made to fit different production standards, while avoiding frequent replacement of the sorting components, which further improves work efficiency.

[0026] 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.

[0027] Please see Figures 1-5 As shown, this embodiment provides a lime particle screening device, including a screening equipment body 1, a pretreatment box 2, and a pretreatment component 3. The pretreatment box 2 is fixedly connected to the top side of the screening equipment body 1, and the pretreatment component 3 is provided in the inner cavity of the pretreatment box 2. The pretreatment component 3 includes a selection component 31 disposed near the bottom of the inner cavity of the pretreatment box 2. The selection component 31 is inclined in the inner cavity of the pretreatment box 2. An adjustment component 32 is provided at the bottom of the selection component 31. A crushing component 33 is provided on one side of the inner cavity of the pretreatment box 2. The crushing component 33 is located above the lower side of the selection component 31.

[0028] The pretreatment box 2 is used to pour in lime particles. The sorting component 31 intercepts particles that are obviously too large or do not meet the particle size requirements in the pretreatment box 2 to reduce the load on the subsequent screening equipment. The adjustment component 32 is used to control the diameter of the particles intercepted by the sorting component 31 so that the sorting process conforms to different production standards. The intercepted particles that do not meet the requirements are rolled to the crushing component 33 by gravity for crushing.

[0029] The improvement in this embodiment lies in the following: During the screening of lime particles, the selection component 31 intercepts particles that are obviously too large or do not meet the particle size requirements in the pretreatment box 2, thereby reducing the load on the subsequent screening equipment. Then, the intercepted non-compliant particles are rolled by gravity to the crushing component 33 for crushing. After meeting the standard of the selection component 31, they enter the screening equipment for screening. This facilitates the crushing of particles that do not meet the screening standards, avoiding the need to transfer them to a dedicated crushing mechanism for crushing and then re-transport them to the screening equipment body 1 for screening. This improves work efficiency. By adjusting the component 32 to change the interception specifications, the selection process can be made to fit different production standards, while avoiding frequent replacement of the selection component 31, which also improves work efficiency.

[0030] Considering that existing screening devices typically have a screening mechanism to sieve lime particles, which are then discharged from the outlet, therefore, if Figure 1 As shown, the screening equipment body 1 includes a shell 11, a screening component 12 is provided on the shell 11, a vibrating motor 13 is provided on the shell 11, a pretreatment box 2 is fixedly installed on the top side of the shell 11, a material discharge port is provided at the bottom of the inner cavity of the pretreatment box 2, and a discharge port 14 is provided on the lower side of the shell 11 away from the pretreatment box 2. When screening is performed, lime particles are poured into the pretreatment box 2, processed by the pretreatment component 3, and then fall into the screening component 12 below for screening. The screened lime particles are discharged through the discharge port 14 for subsequent processing, replacing manual screening, which facilitates the processing of large amounts of materials in a short time, helps to save labor and improve work efficiency.

[0031] To facilitate the conveying of materials into the inner cavity of pretreatment box 2, therefore, as Figures 1-5 As shown, a feed inlet 21 is fixedly installed on the top of the pretreatment box 2. A through hole is opened at the connection between the feed inlet 21 and the pretreatment box 2. When lime needs to be screened, lime particles are poured into the feed inlet 21 and then fall into the pretreatment box 2 through the through hole at the connection between the pretreatment box 2 and the feed inlet 21. After pretreatment, the lime particles enter the screening component 12, which facilitates the pouring of materials and makes subsequent screening work easier.

[0032] Considering that screening equipment is typically designed for materials within a specific particle size range during lime particle pretreatment, large-diameter particles can easily get stuck in the screen, and the high-frequency vibration of the vibrating motor 13 can cause deformation of the mesh due to the impact of large particles. Therefore, to facilitate the selection of particles that are significantly too large or do not meet the particle size requirements, therefore, Figures 2-5 As shown, the sorting component 31 includes a sorting plate 311 fixedly installed at the bottom of the pretreatment box 2. The sorting plate 311 is inclined at the bottom of the pretreatment box 2. Multiple discharge holes 312 are evenly opened on the surface of the sorting plate 311. After the lime particles enter the pretreatment box 2, the particles that meet the aperture of the discharge holes 312 fall into the screening component 12 below for screening. Large-diameter particles that do not meet the requirements are intercepted on the surface of the sorting plate 311. This prevents large-diameter particles that do not meet the screening standards from entering the screening component 12 and hitting the screen, which could easily cause the screen to deform. By intercepting large-diameter particles that do not meet the screening standards in advance by the sorting plate 311, it is beneficial to extend the service life of the screen.

[0033] Considering that the required particle size for lime granules may change when production processes are adjusted or product specifications change, in order to better meet the screening requirements, therefore, as Figures 2-5 As shown, the adjustment assembly 32 includes a slider 321 slidably disposed at the bottom of the sorting plate 311. Multiple sliders 321 are evenly distributed. An adjustment plate 322 is fixedly disposed at the bottom of the slider 321. Multiple grooves 323 adapted to the sliders 321 are opened at the bottom of the sorting plate 311. When the pre-interception standard needs to be adjusted, the number of adjustment plates 322 is increased or decreased. When the diameter of the intercepted lime particles decreases, the inspection port on one side of the pretreatment box 2 is opened, and the slider 321 is inserted into the groove 323. The adjustment plate 322 is placed below the aperture of the sorting plate 311 through the slider 321, so that the diameter of the particles that can pass through the discharge hole 312 decreases. When the diameter of the particles to be intercepted increases, the adjustment plate 322 can be pulled out from the bottom of the sorting plate 311 to reduce the number of adjustment plates 322 and reduce the pre-interception effect. This makes it easier to control the size of the intercepted particles according to different production needs and meet different usage requirements.

[0034] Considering that the large-diameter lime particles to be pre-intercepted need to be transferred to specialized crushing equipment for processing, and then enter screening equipment for grading and screening, the entire process involves relatively many steps. Therefore, if Figures 2-5 As shown, the crushing component 33 includes a rotating rod 331 rotatably mounted on the side of the pretreatment box 2 near the lower side of the sorting plate 311. Multiple sets of blades 332 are evenly distributed on the surface of the rotating rod 331. A motor 333 is mounted on one side of the pretreatment box 2, and the output end of the motor 333 is fixedly connected to one end of the rotating rod 331. Large-diameter particles intercepted on the upper surface of the sorting plate 311 are rolled along the inclined slope of the sorting plate 311 to the crushing component 33 due to gravity. At this time, the motor 333 is started, driving the blades 332 to rotate. The blades 332 then crush the intercepted large-diameter particles, ensuring they conform to the diameter of the discharge hole 312 before being discharged. The particles then enter the screening component 12 for subsequent screening. This facilitates the crushing of particles that do not meet the screening standards, avoiding the need to transfer them to a dedicated crushing mechanism for further crushing and then re-transport them to the screening equipment body 1 for screening, thus improving work efficiency.

[0035] In practical use, the lime particle screening device of this utility model involves pouring lime particles into the pretreatment box 2. After entering the inner cavity of the pretreatment box 2, particles that conform to the aperture of the discharge hole 312 fall into the screening component 12 below for screening. Large-diameter particles that do not meet the requirements are intercepted on the surface of the selection plate 311. Under the influence of gravity, the large-diameter particles intercepted on the upper surface of the selection plate 311 roll along the inclined slope of the selection plate 311 to the crushing component 33. At this time, the motor 333 is started to drive the blades 332 to rotate. Then, the blades 332 crush the intercepted large-diameter particles to make them conform to the requirements. After the material is discharged from the discharge hole 312, it enters the screening assembly 12 for subsequent screening. When the pre-interception standard needs to be adjusted, it can be achieved by increasing or decreasing the number of adjusting plates 322. When the intercepted lime particle size decreases, the inspection port on one side of the pretreatment box 2 is opened, and the slider 321 is inserted into the chute 323. The adjusting plate 322 is placed below the aperture of the selection plate 311 through the slider 321, so that the particle diameter that can pass through the discharge hole 312 decreases. When the particle size to be intercepted increases, the adjusting plate 322 can be pulled out from the bottom of the selection plate 311 to reduce the number of adjusting plates 322 and reduce the pre-interception effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
