Description

Technical Field

[0001] This utility model relates to the field of salt production, and in particular to a circular vibrating screen device for salt production. Background Technology

[0002] In the salt production process, the vibrating screen, as a key piece of equipment for dry salt screening, plays a crucial role in separating salt particles of different sizes and ensuring product quality. Its screening efficiency and equipment stability directly affect the efficiency of subsequent production stages and the quality of the finished product. In the salt and calcium workshop of the salt production branch, dry salt must be screened by a vibrating screen to remove impurities and substandard particles before it can proceed to subsequent packaging and processing steps.

[0003] Traditional salt vibrating screens use a conventional linear vibrating screen design, where the salt material moves in a straight line in one direction. This makes the salt material prone to accumulating or deviating from its course, leading to screen blockage and low screening efficiency. Utility Model Content

[0004] To address the shortcomings or deficiencies in the existing technology, this utility model provides a circular vibrating screen device for salt production. This device can break up salt clumps, ensuring uniform dispersion of salt particles. It also allows the salt to continuously tumble and jump during the sieving process, preventing salt accumulation and clogging of the screen holes. Furthermore, it can perform multi-stage sieving of salt particles, improving sieving accuracy and ensuring the purity of the finished product.

[0005] The technical solution of this utility model is: a circular vibrating screen device for salt production, comprising a mounting frame, a collection frame on the mounting frame, four swing springs fixedly connected to the mounting frame, a screen frame fixedly connected between the four swing springs, a coarse screen and a fine screen fixedly connected to the screen frame, the coarse screen being located above the fine screen, the collection frame on the mounting frame being located below the fine screen, two sliding blocks slidably connected to the mounting frame, the two sliding blocks being symmetrically arranged, two return springs connecting the mounting frame to each of the two sliding blocks, and each of the two sliding blocks having... The slide is connected by a sliding sleeve. Two telescopic springs are connected between the slide block and the sliding sleeve. The telescopic springs are sleeved on the slide block. A camshaft is rotatably connected between the two sliding sleeves. A motor frame is fixedly connected to one of the sliding sleeves. A servo motor is fixedly connected to the motor frame. The output shaft of the servo motor is fixedly connected to the camshaft. Two connecting ring frames are fixedly connected to the screen frame. The two connecting ring frames are symmetrically arranged. The camshaft is rotatably connected to both connecting ring frames. A protective shell is fixedly connected to the top of the mounting frame. The camshaft passes through the protective shell.

[0006] Beneficial effects: When the operator starts the servo motor, the eccentric motion of the camshaft drives the screen frame, coarse screen, and fine screen to periodically oscillate and vibrate through two connecting rings. When salt particles fall from above onto the coarse screen, the screen frame drives the coarse and fine screens to oscillate and vibrate periodically, which can break up salt particles clumping together and ensure that the salt particles are evenly dispersed. It can also make the salt continuously roll and jump during the sieving process, avoiding the accumulation of salt particles that clog the screen holes. At the same time, it can perform multi-stage sieving of salt particles, improve sieving accuracy, and ensure the purity of the finished product. Attached Figure Description

Detailed Implementation

[0011] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0012] Example 1

[0013] A circular vibrating screen device for salt production, such as Figures 1-3As shown, the device includes a mounting frame 1, on which a collection frame is provided. Four swing springs 2 are fixedly connected to the mounting frame 1, and a screen frame 3 is fixedly connected between the four swing springs 2. A coarse screen 41 and a fine screen 42 are fixedly connected to the screen frame 3, with the coarse screen 41 located above the fine screen 42. The collection frame 3 is located below the fine screen 42. Two sliding blocks 5 are slidably connected to the mounting frame 1, and the two sliding blocks 5 are symmetrically arranged. Two return springs 6 are connected between the mounting frame 1 and the two sliding blocks 5. Sliding sleeves 71 are slidably connected to each of the two sliding blocks 5. Two telescopic springs 72 are connected between the sliding sleeves 71. The telescopic springs 72 are sleeved on the sliding block 5. A camshaft 8 is rotatably connected between the two sliding sleeves 71. A motor frame 9 is fixedly connected to one of the sliding sleeves 71. A servo motor 10 is fixedly connected to the motor frame 9. The output shaft of the servo motor 10 is fixedly connected to the camshaft 8. Two connecting ring frames 11 are fixedly connected to the screen frame 3. The two connecting ring frames 11 are symmetrically arranged. The camshaft 8 is rotatably connected to both connecting ring frames 11. A protective shell 12 is fixedly connected to the top of the mounting frame 1. The camshaft 8 passes through the protective shell 12.

[0014] The operator starts the servo motor 10, which drives the camshaft 8 to rotate. During rotation, the camshaft 8 generates an eccentric motion. Under the influence of this eccentric motion, the motor frame 9, the servo motor 10, and the two sliding sleeves 71 simultaneously reciprocate vertically and horizontally. The extension spring 72 is continuously compressed or stretched. The horizontal reciprocating motion of the sliding sleeves 71 drives the sliding block 5 to reciprocate horizontally, causing the return spring 6 to be continuously compressed or stretched. The eccentric motion of the camshaft 8, through the two connecting rings 11, causes the screen frame 3, the coarse screen 41, and the fine screen 42 to periodically oscillate and vibrate. When salt particles pass through… When the salt falls onto the coarse screen 41, the coarse screen 41 will perform preliminary screening of the salt particles, intercepting large salt particles. The remaining salt particles will fall onto the fine screen 42, where the fine screen 42 will perform secondary screening of the salt particles. The fine salt particles will fall downward into the collection frame on the mounting frame 1. In this way, the screen frame 3 drives the coarse screen 41 and the fine screen 42 to perform periodic oscillation and vibration, which can break up salt particles clumping together, ensuring that the salt particles are evenly dispersed. It can also make the salt material roll and jump continuously during the screening process, avoiding the accumulation of salt material and clogging of the screen holes. At the same time, it can perform multi-stage screening of salt particles, improve screening accuracy, and ensure the purity of the finished product.

[0015] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
