Description

Technical Field

[0001] The utility model relates to the technical field of industrial salt production, in particular to a screening device for industrial salt production. Background Art

[0002] Industrial salt is one of the most basic raw materials in the chemical industry, and its main component is sodium chloride. It is widely used in many fields such as chlor-alkali industry, soap manufacturing, ceramic manufacturing, glass production, daily necessities manufacturing, petrochemical industry, etc., and is known as the "mother of the chemical industry". After the industrial salt is dried, in order to meet different production needs, the dried salt needs to be screened and classified with different coarseness and fineness. There are many ways to screen industrial salt, among which it is more common to use a small vibrating screening machine to screen industrial salt.

[0003] When two kinds of industrial salts with different coarseness and fineness need to be screened out for classification, a small vibration screening machine can be used to screen and classify the industrial salt. However, a single screen of a small vibration screening machine can only screen out industrial salt of one coarseness and fineness. When industrial salts of other coarseness and fineness need to be screened, the screen must be replaced, which is not only inconvenient but also affects work efficiency. To this end, we propose a screening device for industrial salt production. Utility Model Content

[0024] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6The rotating mechanism shown in the figure includes a connecting column 18, which is fixedly connected to the middle part of the front end of one of the gears 12, and the connecting column 18 movably penetrates the front end inner wall of the box body 3, and the front end of the connecting column 18 is fixedly connected to a concave block 6, and a handle 7 is fixedly connected between the front edges of the inner sides of the concave block 6, and a limiting mechanism is provided between the concave block 6 and the box body 3.

[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 The limiting mechanism shown in the figure includes two symmetrical sleeves 11 and four limiting holes 17. The two sleeves 11 are respectively fixedly connected to the inner rear end surface of the concave block 6, and the interiors of the two sleeves 11 are slidably inserted with limiting columns 10. The two limiting columns 10 are both movable and penetrate the rear end inner wall of the concave block 6, and the front ends of the two limiting columns 10 are commonly fixedly connected with an arc plate 9, and the outer walls of the two limiting columns 10 are fixedly sleeved with a ring 19, and the two rings 19 are respectively fixedly connected to the inner walls of the two sleeves 11 with springs 20, and the two springs 20 are respectively slidably sleeved on the outer walls of the two limiting columns 10, and four limiting holes 17 are opened at the front end of the box body 3 in an annular array around the axis of the connecting column 18, and the two limiting columns 10 are respectively slidably matched with two of the limiting holes 17.

[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 , a non-slip pad 8 is fixedly sleeved on the outer wall of the handle 7 shown in the figure, and the non-slip pad 8 is made of rubber material; by providing the non-slip pad 8, the handle 7 can be not only non-slip but also more comfortable to hold.

[0027] See also Figure 1 , universal wheels 4 are fixedly installed at the four corners of the lower end of the screening machine body 1 shown in the figure; by setting the universal wheels 4, the screening machine body 1 is easy to move.

[0028] In this embodiment, when the device is used to screen industrial salt, when a sieve plate 13 with a smaller aperture is needed to screen the industrial salt, the screening machine body 1 is first started, and the screening machine body 1 can drive the sieve frame 2 to vibrate, and the sieve frame 2 can drive the box body 3, the multiple rotating columns 5 and the multiple sieve plates 13 to vibrate synchronously, and then the industrial salt to be screened is poured into the sieve frame 2, and the industrial salt will contact the multiple horizontal sieve plates 13 on the inner side of the sieve frame 2, and the multiple horizontal sieve plates 13 are provided with multiple sieve holes a14, so the poured industrial salt can be screened.

[0029] When it is necessary to switch to a sieve plate 13 with a larger aperture, first hold the handle 7 and the curved plate 9 at the same time, and then squeeze the curved plate 9 in the direction of the handle 7. At this time, the curved plate 9 can drive the two limit columns 10 to move together, and the two limit columns 10 can respectively drive the two circular rings 19 to slide in the two sleeves 11 respectively, and the spring 20 connected between the circular rings 19 and the sleeves 11 can be squeezed until the two limit columns 10 slide out of the two symmetrical limit holes 17 at the front end of the box body 3 respectively, and then rotate the handle 7 and the curved plate 9 ninety degrees at the same time, and the concave block 6 will rotate ninety degrees accordingly, and the concave block 6 will drive the connecting column 18 to rotate ninety degrees in the inner wall of the box body 3, and the connecting column 18 can drive a gear 12 connected to it to rotate ninety degrees. Since the two adjacent gears 12 are meshed, multiple gears 12 will rotate together. Ninety degrees, the multiple gears 12 will drive the multiple rotating columns 5 to rotate ninety degrees respectively, and the four sieve plates 13 on the outer walls of the multiple rotating columns 5 will rotate ninety degrees together, then the sieve plate 13 originally in a horizontal state will rotate to a vertical state, and the sieve plate 13 originally in a vertical state will rotate to a horizontal state, and then the arc plate 9 is released, and under the action of the spring 20, the arc plate 9, the two limit columns 10 and the two rings 19 can be reset. At this time, the two limit columns 10 will automatically insert into the two upper and lower symmetrical limit holes 17, so as to fix the multiple gears 12, the multiple rotating columns 5 and the multiple sieve plates 13, and the sieve plate 13 with multiple sieve holes b15 can be used for screening industrial salt. Since the radius of the sieve hole b15 is larger than the radius of the sieve hole a14, it can be switched to the sieve plate 13 with a larger aperture to screen the industrial salt.

[0030] It should be noted that, using the present screening device, industrial salt can be screened into two different coarsenesses, and the two sieve plates 13 of different coarsenesses are very easy to switch between. The switch can be completed by simply turning the screen. Compared with the traditional small-scale industrial salt vibration screening machine that requires manual disassembly, replacement and installation of the screen, the present screening device is more convenient and faster when switching between sieve plates 13 of different coarsenesses, thereby improving work efficiency.

[0033] In this embodiment, when the concave block 6 is rotated ninety degrees clockwise, the concave block 6 will fit on the side surface of the triangular block 16. When the concave block 6 is rotated ninety degrees counterclockwise, the concave block 6 will fit on the upper end surface of the triangular block 16. The triangular block 16 can assist in positioning the concave block 6, thereby indirectly facilitating the alignment of the limit column 10 and the limit hole 17.
