Description

Technical Field

[0001] This utility model relates to the field of industrial salt production, specifically to an automatic screening and grading machine for industrial salt production. Background Technology

[0002] Mineral salt, also known as "well salt" or "underground salt," is a type of salt extracted and refined from underground salt mines. It is primarily produced by drilling to extract natural underground brine and by processing mined rock salt. Mineral salt is buried 100 to 3000 meters underground and requires drilling, water injection for dissolution, and extraction for processing. The production process includes two main parts: mining and salt production.

[0003] In the prior art, such as in the publication number CN222197749U, a screening device for industrial salt production is disclosed. It includes a screening machine body and a screen frame installed on the screening machine body. A box is fixedly connected to the front end of the screen frame. Multiple rotating columns are linearly arrayed and rotatably installed on the inner wall of the rear end of the box. The rear ends of the multiple rotating columns are rotatably connected to the inner rear end of the screen frame.

[0004] While the aforementioned patent makes switching between different screen sizes more convenient and faster, improving work efficiency, during the screening and feeding of industrial salt, the particles accumulate together, resulting in a slow feeding speed and affecting the transport of salt particles. At the same time, when the salt particles are screened by grade, the screen plates must be replaced, thereby reducing the efficiency of grading and screening. Therefore, an automatic screening and grading machine for industrial salt production is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, such as the slow feeding speed caused by granules accumulating during the screening and feeding process of industrial salt production, which affects the transport of salt granules, and the need to replace screen plates during grading and screening, thus reducing the efficiency of grading and screening, this utility model proposes an automatic screening and grading machine for industrial salt production.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The automatic screening and grading machine for industrial salt production of this utility model includes a processing box; a trapezoidal feeding hopper with a wider top and narrower bottom is provided on one side of the top of the processing box, a flow guiding component is provided inside the processing box below the trapezoidal feeding hopper, and a screening component is provided on one side of the inside of the processing box; the flow guiding component includes a U-shaped outer plate, A springs are provided at the four corners of the top surface of the U-shaped outer plate, the top of the A springs are connected to the U-shaped inner plate, and A vibration motor is provided at the bottom of the U-shaped inner plate; the screening component includes a receiving box, a vibration box is provided inside the receiving box, B springs are provided on both sides of the vibration box, B vibration motor is provided at the bottom of the vibration box, A square frame and B square frame are symmetrically arranged on the upper and lower axes inside the vibration box, and filter screens are provided inside both the A square frame and B square frame, and discharge troughs are symmetrically opened on the front of the vibration box; guide plates are symmetrically arranged on the upper and lower axes of the surface of the processing box, and the guide plates are respectively connected to the upper and lower discharge troughs of the vibration box, and a secondary box is provided at the bottom of the processing box.

[0007] Preferably, both the U-shaped outer panel and the U-shaped inner panel are inclined, the opening at the top of the receiving box is located on one side of the bottom of the U-shaped outer panel, and the receiving box as a whole is inclined.

[0008] Preferably, a U-shaped groove is provided on the front of the receiving box, and the filter mesh aperture inside the square frame A is larger than the filter mesh aperture inside the square frame B.

[0009] Preferably, the upper guide plate of the guide plate is connected to the discharge chute at the top of the vibrating box, and the lower guide plate of the guide plate is connected to the discharge chute at the bottom of the vibrating box.

[0010] Preferably, the U-shaped inner plate is elastically connected to the U-shaped outer plate via spring A, and the vibration box is elastically connected to the inner wall of the receiving box via spring B.

[0011] Preferably, the auxiliary box is located at the bottom of the processing box and is perpendicular to the B-shaped frame at the bottom of the vibration box, and the outlet of the trapezoidal feeding hopper is directly opposite the U-shaped inner plate of the flow guiding component.

[0012] The advantages of this utility model are:

[0013] 1. This utility model achieves the function of preventing the accumulation of industrial salt by linking the U-shaped inner plate of the flow guiding component with the A vibration motor; the A vibration motor drives the U-shaped inner plate to vibrate inside the U-shaped outer plate through the A spring, and combined with the inclined setting of the U-shaped inner plate, the industrial salt is evenly shaken into the receiving box, which solves the problem of slow material discharge caused by the accumulation of salt particles during feeding and improves the conveying efficiency.

[0014] 2. This utility model achieves automatic grading and sieving function through the coordinated design of the double-layer filter screens of the A square frame and B square frame of the screening component and the B vibration motor. The B vibration motor drives the vibrating box to vibrate at high frequency through the B spring, so that the industrial salt passes through the upper large-pore filter screen and the lower small-pore filter screen in sequence, separating particles of different sizes and discharging them from the upper and lower discharge troughs. This solves the problem of cumbersome replacement of traditional screen plates and improves the grading and sieving efficiency. Through the overall inclined setting of the receiving box and the connection design between the guide plate and the discharge trough, the directional flow function of the sorted particles is realized. The inclined layout of the receiving box, together with the upper and lower guide plates corresponding to the upper and lower discharge troughs of the vibrating box, ensures that salt particles of different sizes are quickly separated and slide out along the guide plates, avoiding mixing or retention of particles after screening and optimizing the smoothness of the discharge path.

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 scope of protection of the present utility model.

[0023] Please see Figures 1-4 As shown, the automatic screening and grading machine for industrial salt production includes a processing box 1; a trapezoidal feeding hopper 2, wider at the top and narrower at the bottom, is provided on one side of the top of the processing box 1; a flow guiding component 3 is provided inside the processing box 1 below the feeding hopper 2; a screening component 4 is provided on one side of the inside of the processing box 1; the flow guiding component 3 includes a U-shaped outer plate 31, with A springs 32 at the four corners of the top surface of the U-shaped outer plate 31; the top of the A springs 32 is connected to the U-shaped inner plate 33; and an A vibration motor 34 is provided at the bottom of the U-shaped inner plate 33; the screening component 4 includes a receiving box 41. 1. An internal vibration chamber 42 is provided. B springs 43 are provided on both sides of the vibration chamber 42. B vibration motor 44 is provided at the bottom of the vibration chamber 42. A square frame 45 and B square frame 46 are symmetrically arranged on the upper and lower axes inside the vibration chamber 42. Filter screens 47 are provided inside both square frame 45 and B square frame 46. Discharge troughs 48 are symmetrically opened on the front of the vibration chamber 42. Guide plates 5 are symmetrically arranged on the upper and lower axes on the surface of the processing box 1. The guide plates 5 are respectively connected to the upper and lower discharge troughs 48 of the vibration chamber 42. A secondary box 6 is provided at the bottom of the processing box 1.

[0024] During operation, a trapezoidal feeding hopper 2, wider at the top and narrower at the bottom, is welded to one side of the top of the processing box 1. A flow guiding assembly 3 is fixed below the feeding hopper 2, and a screening assembly 4 is installed on the other side of the interior of the processing box 1. The flow guiding assembly 3 is composed of a U-shaped outer plate 31, with A springs 32 fixed to the four corners of its top surface by bolts. A U-shaped inner plate 33 is welded to the top of the A springs 32, and an A vibration motor 34 is bolted to the bottom of the U-shaped inner plate 33. The screening assembly 4 includes a receiving box 41, inside which a vibrating box 42 is placed. The two sides of the vibrating box 42 are connected to the inner wall of the receiving box 41 by B springs 43. A B vibration motor 44 is installed at the bottom of the vibrating box 42. A square frame 45 and a square frame 46 are symmetrically embedded inside the vibrating box 42, and filter screens 47 are clipped into both frames. Discharge slots 48 are opened on the front of the vibrating box 42. The upper and lower guide plates 5 are welded to the surface of the processing box 1. The upper guide plate is aligned with the upper discharge chute 48 of the vibrating box 42, and the lower guide plate is aligned with the lower discharge chute 48. The auxiliary box 6 is bolted to the bottom of the processing box 1. The U-shaped inner plate 33 is driven to vibrate by the A vibration motor 34 of the flow guiding component 3. Combined with the elastic support of the A spring 32, the industrial salt is quickly dispersed and guided to prevent the accumulation of feed. The double-layer filter screen 47 of the screening component 4 is linked with the B vibration motor 44 to automatically complete the particle classification and screening without the need for manual replacement of the screen plate, which greatly improves the screening efficiency.

[0025] Furthermore, both the U-shaped outer panel 31 and the U-shaped inner panel 33 are inclined, and the opening at the top of the receiving box 41 is located on one side of the bottom of the U-shaped outer panel 31. The receiving box 41 is inclined as a whole.

[0026] During operation, the U-shaped outer plate 31 and the U-shaped inner plate 33 are welded to the processing box 1 at a 15° angle. The top opening of the receiving box 41 is directly opposite the bottom inclined end of the U-shaped outer plate 31. The receiving box 41 is fixed at a 10° angle. The inclined layout of the flow guiding component 3 guides the salt particles to slide naturally into the receiving box 41. The inclination angle of the receiving box 41 optimizes the path of the salt particles into the vibrating box 42, reducing the risk of jamming.

[0027] Furthermore, a U-shaped groove 49 is opened on the front of the receiving box 41, and the filter screen 47 inside the square frame A 45 has a larger aperture than the filter screen 47 inside the square frame B 46.

[0028] During operation, the receiving box 41 has a U-shaped groove 49 cut on the front. The filter screen 47 of the square frame A 45 has a pore size of 3mm, and the filter screen 47 of the square frame B 46 has a pore size of 1mm. The U-shaped groove 49 collects residual salt particles from the screening and avoids clogging. The difference in pore size between the double-layer filter screen 47 enables automatic grading of coarse and fine particles, ensuring screening accuracy.

[0029] Furthermore, the upper guide plate of the guide plate 5 is connected to the discharge chute 48 at the top of the vibrating box 42, and the lower guide plate of the guide plate 5 is connected to the discharge chute 48 at the bottom of the vibrating box 42.

[0030] During operation, the upper guide plate extends at an angle to the side outlet of the processing box 1, and the lower guide plate extends at an angle to the top of the auxiliary box 6. The guide plate 5 is directly connected to the discharge chute 48. Large particles after sorting are discharged through the upper guide plate, and small particles fall into the auxiliary box 6 through the lower guide plate, thus achieving graded output.

[0031] Furthermore, the U-shaped inner plate 33 is elastically connected to the U-shaped outer plate 31 via spring A 32, and the vibrating box 42 is elastically connected to the inner wall of the receiving box 41 via spring B 43.

[0032] During operation, the U-shaped inner plate 33 forms an elastic suspension structure with the U-shaped outer plate 31 through spring A 32, and the vibrating box 42 forms an elastic support structure with the receiving box 41 through spring B 43. The elastic connection structure buffers the vibration impact, reduces equipment wear, and at the same time enhances the vibration amplitude of the U-shaped inner plate 33 and the vibrating box 42, thereby improving the guiding and screening effect.

[0033] Furthermore, the auxiliary box 6 is located at the bottom of the processing box 1 and is perpendicular to the B square frame 46 at the bottom of the vibration box 42, and the outlet of the trapezoidal feeding hopper 2 is directly opposite the U-shaped inner plate 33 of the flow guiding component 3.

[0034] During operation, the top opening of the auxiliary box 6 is vertically aligned with the B-shaped frame 46 at the bottom of the vibrating box 42, and the center line of the outlet of the trapezoidal feeding hopper 2 coincides with the center line of the U-shaped inner plate 33. The auxiliary box 6 accurately collects the smallest salt particles, and the trapezoidal feeding hopper 2 feeds the material directionally to the central area of ​​the U-shaped inner plate 33 to avoid salt particles from scattering and improve the uniformity of flow.

[0035] Working principle: Industrial salt falls from the trapezoidal feeding hopper 2 into the guiding component 3 inside the processing box 1. Vibration motor A 34 drives the U-shaped inner plate 33 to vibrate at high frequency within the inclined U-shaped outer plate 31 via spring A 32, evenly dispersing the salt particles into the vibrating box 42 of the receiving box 41. Vibration motor B 44 drives the vibrating box 42 to vibrate via spring B 43, causing the salt particles to pass through the large-aperture filter screen 47 of square frame A 45 and the small-aperture filter screen 47 of square frame B 46 for grading and screening. Larger particles are discharged from the upper discharge chute 48 through the guide plate 5, smaller particles slide into the guide plate 5 from the lower discharge chute 48, and the finest particles pass through square frame B 46 and fall into the auxiliary box 6, realizing multi-stage automatic screening and collection.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
