Therefore, a technical measure is proposed to solve the problem that the existing technology lacks a mechanism to block the quartz sand. In the inclined screening device, the falling speed of the quartz sand will become faster and faster, which may cause some quartz sand to pass through the screening device without being fully screened.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] This specific embodiment is a quartz sand screening device, and its structural diagram is as follows Figure 1 、 Figure 2As shown, it includes a body 1, which is tilted, and a sieve plate 3 is provided at the bottom of the body 1. The sieve plate 3 is provided with evenly distributed sieve holes 4. A deceleration component 2 is installed in the middle position of the upper part of the body 1, and two groups of side plates 9 are symmetrically installed in the middle position of the lower part of the body 1. The two groups of side plates 9 are installed with vibration motors 10. An extension plate 5 is provided at the lower end of the body 1, and the extension plate 5 is horizontally arranged. A filling box 12 is provided at the high end of the body 1. The filling box 12 is large at the top and small at the bottom. A discharge port 13 is provided at the lower part of the side of the filling box 12 facing the sieve plate 3. A support frame 8 is installed at the bottom of the body 1, and a shock-absorbing base 7 is installed at the lower end of the support frame 8. A first collecting box 6 is provided at the bottom of the extension plate 5, and a second collecting box 11 is provided at the bottom of the sieve plate 3. Two groups of symmetrically distributed bottom plates 14 are installed in the middle position of the upper surface of the body 1, and the deceleration component 2 is threadedly connected to the bottom plate 14. When screening quartz sand, The crushed quartz sand is put into the feeding box 12, and then the quartz sand falls into the sieve plate 3 through the discharge port 13, and the vibration motor 10 is started. The vibration motor 10 transmits the vibration to the side plate 9, and the side plate 9 transmits the vibration to the main body 1, and the main body 1 transmits the vibration to the sieve plate 3. The sieve plate 3 vibrates the quartz sand to accelerate the falling of the quartz sand and prevent the quartz sand from clogging the sieve hole 4. The quartz sand with particles that meet the requirements falls into the second collecting box 11, and the quartz sand with larger particles falls through the main body 1 into the extension plate 5, and then under the action of the vibration motor 10, it gradually moves horizontally and falls into the first collecting box 6, and the vibration generated by the vibration motor 10 is absorbed by the shock-absorbing base 7 to prevent the vibration motor 10 from causing adverse effects on other machines. When screening the quartz sand, the deceleration component 2 is started synchronously to decelerate the quartz sand to prevent the quartz sand from passing through the sieve plate 3 too quickly.
[0026] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, the deceleration assembly 2 includes a connecting plate 201, which has two groups. Bolts 204 are symmetrically passed through the two ends of the connecting plate 201. The connecting plate 201 is connected to the bottom plate 14 through the bolts 204. A vertical plate 202 is installed in the middle position of the upper surface of the connecting plate 201. There are two groups of vertical plates 202. The upper ends of the two groups of vertical plates 202 are connected to the mounting plate 203. A cylinder 206 is installed in the middle position of the mounting plate 203. The lower end of the cylinder 206 is connected to the lifting plate 205. The lifting plate 205 is slidably engaged with a card plate 207. A plurality of groups of evenly distributed springs 209 are installed on the upper surface of the card plate 207. The upper end of the spring 209 is fixedly installed above the inner part of the lifting plate 205. A baffle 208 is installed in the middle position of the lower surface of the card plate 207. The baffle 208 is tilted. The tilt angle of the baffle 208 is adapted to the body 1. Start the cylinder 206. The lifting plate 205 is driven to move downward, and the downward movement of the lifting plate 205 drives the spring 209 and the baffle 208 to move downward. When the baffle 208 moves downward and contacts the upper surface of the quartz sand, a downward force is applied to the quartz sand, and the quartz sand is resisted, and the quartz sand does not continue to flow. When the baffle 208 continues to move downward, the card plate 207 is squeezed, and the card plate 207 squeezes the spring 209, and the spring 209 is compressed. At this time, the falling quartz sand is blocked at the position between the baffle 208 and the injection box 12, and the speed of the quartz sand is zero. Then the cylinder 206 retracts and drives the lifting plate 205, the baffle 208, and the spring 209 to move upward, releasing the obstruction to the quartz sand. The quartz sand begins to roll (accelerates from zero) and is screened through the sieve plate 3. When the baffle 208 rises, the spring 209 returns to its initial state.
[0027] Working principle: When quartz sand is screened, the crushed quartz sand is put into the injection box 12, and then the quartz sand falls into the sieve plate 3 through the discharge port 13, and the vibration motor 10 is started. The vibration motor 10 transmits the vibration to the side plate 9, and the side plate 9 transmits the vibration to the main body 1, and the main body 1 transmits the vibration to the sieve plate 3. The sieve plate 3 vibrates the quartz sand to accelerate the falling of the quartz sand and prevent the quartz sand from clogging the sieve hole 4. The quartz sand with particles that meet the requirements falls into the second collecting box 11, and the quartz sand with larger particles falls through the main body 1 into the extension plate 5. Then, under the action of the vibration motor 10, it gradually moves horizontally and falls into the first collecting box 6, and the vibration generated by the vibration motor 10 is absorbed by the shock-absorbing base 7 to prevent the vibration motor 10 from causing adverse effects on other machines.
[0028] When screening the quartz sand, the deceleration component 2 is started synchronously to decelerate the quartz sand to prevent the quartz sand from passing through the sieve plate 3 too quickly. Specifically, the cylinder 206 is started to drive the lifting plate 205 to move downward. The lifting plate 205 moves downward to drive the spring 209 and the baffle 208 to move downward. When the baffle 208 moves downward and contacts the upper surface of the quartz sand, a downward force is applied to the quartz sand. The quartz sand is resisted and does not continue to flow. When the baffle 208 continues to move downward, it squeezes the card plate 207, and the card plate 207 squeezes the spring 209. The spring 209 is compressed, and the falling quartz sand It is blocked at the position between the baffle 208 and the injection box 12, and the speed of the quartz sand is zero. Then the cylinder 206 retracts to drive the lifting plate 205, the baffle 208, and the spring 209 to move upward, releasing the blockage of the quartz sand. The quartz sand begins to roll (accelerate from zero) and is screened through the sieve plate 3. When the baffle 208 rises, the spring 209 returns to its initial state. Through the setting of the deceleration component 2, the quartz sand is blocked, which increases the time that the quartz sand stays on the sieve plate 3, preventing some quartz sand from passing through the screening device without being screened, thereby improving the screening effect of the quartz sand.
