Description

Technical Field

[0001] This application relates to the field of dewatering screen technology, and more particularly to a dewatering screen with a cleaning function. Background Technology

[0002] A dewatering screen is a screening device that integrates dewatering, desliming, and demediuming functions. It is mainly used for material processing in industries such as mining, building materials, chemicals, and sand and gravel aggregates. By making the material vibrate at high frequency on the screen surface, water, fine mud, impurities, etc. pass through the screen and are discharged, achieving solid-liquid separation and material classification. However, since sand often contains impurities such as mud, stone powder, metal oxides, and organic matter, although traditional dewatering screens can remove water, they have limited separation effects on fine mud and stone powder attached to the surface of sand particles or mixed in the gaps between particles. This leads to a decrease in the bonding force of cementitious materials such as cement in subsequent processing, affecting the quality of the finished product. Utility Model Content

Several nozzles are provided on the liquid storage pipe, which are spaced apart along the length of the liquid storage pipe. The output end of the nozzles faces the sieve plate.

[0007] The machine body is also equipped with an extrusion assembly, which includes a drive rod. The drive rod is rotatably mounted on the machine body. One end of the drive rod extends to the outside of the machine body and is connected to a drive motor. The part of the drive rod inside the machine body is equipped with a pressure roller. The pressure roller is located above the screen plate and forms an extrusion gap with the screen plate.

The spraying assembly is located between the propulsion assembly and the extrusion assembly. The propulsion assembly includes a push rod component. The piston end of the push rod component passes through the storage seat and is connected to a support plate. Several guide plate components are provided on the support plate, which are spaced apart along the length of the support plate. The guide plate components include a plate body.

[0009] The push rod assembly allows the plate components to be oriented towards or away from the sieve plate.

[0010] In one embodiment, the guide plate component further includes a bearing seat, which is disposed on the support plate. A support rod is mounted on the bearing seat, and the plate body is provided with two sets of support rods symmetrically distributed on both sides of the support rods.

[0011] With the cooperation of the bearing housing, the support rod can drive the plate to rotate in a circular motion.

[0017] The advantages or beneficial effects of the above technical solutions include at least the following:

[0018] This application discloses a dewatering screen with a cleaning function. Material on the screen plate moves along the length of the screen plate with the assistance of a vibrating motor. Because the screen plate has evenly distributed screen holes, water can flow out through the screen holes during the movement, achieving dewatering. As the material moves below the liquid storage pipe of the spray assembly, the liquid in the storage pipe is sprayed onto the material through the spray nozzles, removing impurities and sludge adhering to the material surface, further improving the cleanliness of the material. After spraying, the material moves to the pressure roller of the extrusion assembly. The pressure roller rotates through the cooperation of a drive rod and a drive motor, extruding the material and further dewatering it by removing the water adhering to the spray. The material then moves along the screen plate until it enters the next process. Through the cooperation of the spray assembly and the extrusion assembly, the material can be cleaned and extruded again, ensuring the cleanliness and dewatering efficiency of the processed material. This solves the problem of limited operation and low product quality caused by existing dewatering screens that can only perform a single dewatering operation. Attached Figure Description

[0035] Reference Figures 1-4 A dewatering screen with a cleaning function includes a base 1, an organic body 2 mounted on the base 1, a screen plate 21 mounted on the organic body 2, the screen plate 21 having uniformly distributed screen holes to connect the interior and exterior of the organic body 2, a support 22 mounted on the organic body 2, and two sets of spaced-apart vibrating motors 221 mounted on the support 22. The two sets of vibrating motors 221 are usually parallel and symmetrically mounted on both sides or both ends of the dewatering screen, and each motor shaft end is equipped with an adjustable eccentric block. By adjusting the included angle of the eccentric block, the magnitude and direction of the centrifugal force can be changed. Under the action of horizontal excitation force, the screen plate 21 drives the material to perform linear reciprocating vibration in a direction perpendicular to the motor axis. The linear movement of the material is achieved by the two sets of vibrating motors 221, which is a conventional method in the prior art.

[0036] The machine body 2 is equipped with a spray assembly 3, which is used to clean the mud and sand again. The spray assembly 3 includes a liquid storage pipe 31, which is set on the machine body 2 and located between the support 22 and the screen plate 21. One end of the liquid storage pipe 31 extends to the outside of the machine body 2 and is provided with a liquid inlet 311. The liquid inlet 311 is connected to an external water source through a pipeline. Several nozzles 32 are provided on the liquid storage pipe 31 and are spaced apart along the length of the liquid storage pipe 31. The output end of the nozzles 32 faces the screen plate 21. The nozzles 32 can be high-pressure nozzles with fan-shaped nozzles. The liquid used for external cleaning enters the liquid storage pipe 31 through the liquid inlet 311 and is sprayed out through the nozzles 32.

[0037] The machine body 2 is also equipped with an extrusion assembly 4, which includes a drive rod 41. The drive rod 41 is rotatably mounted on the machine body 2. A bearing seat 532 is provided at the connection between the drive rod 41 and the machine body 2. One end of the drive rod 41 extends to the outside of the machine body 2 and is connected to a drive motor 42. The drive motor 42 and the drive rod 41 are connected by a coupling. The drive motor 42 is a servo drive motor in the prior art. The part of the drive rod 41 located inside the machine body 2 is equipped with a pressure roller 43. The pressure roller 43 is located above the screen plate 21 and forms an extrusion gap with the screen plate 21. After the material enters the extrusion gap, it contacts the outer periphery of the pressure roller 43 to further improve the dewatering of the material.

[0038] Based on the above structure, the material enters the screen plate 21 of the machine body 2 from the sand washing machine. Since the screen plate 21 has screen holes, and two sets of vibrating motors 221 vibrate and drive the material to move along the straight line of the screen plate 21, the material will shake during movement, causing water to fall through the screen holes to the bottom of the machine body 2 for dehydration. Because the machine body 2 is equipped with a spray assembly 3, when the material moves to below the liquid storage pipe 31 under the cooperation of the vibrating motors 221 and the screen plate 21, the liquid in the liquid storage pipe 31 washes the material through the spray nozzles 32, causing impurities on the material to fall off, thus preventing impurities from remaining on the material and affecting its quality. Simultaneously, it washes the screen holes on the screen plate 21. Furthermore, because a squeezing assembly 4 is also provided on one side of the machine body 2, when the material… After rinsing with the help of the spray assembly 3, the rinsing process can also break up clumps of material to prevent material accumulation. When the material moves to the position of the pressure roller 43 in the extrusion assembly 4, the material is positioned between the pressure roller 43 and the screen plate 21. The pressure roller 43 rotates with the help of the drive rod 41 and the drive motor 42, which squeezes the material to remove moisture from the material again and further improve the dewatering effect. Through the cooperation of the spray assembly 3 and the extrusion assembly 4, the material can achieve three operations in the machine body 2: vibration, spraying and extrusion. Vibration loosens the material, spraying cleans impurities, and extrusion removes moisture, thereby improving the efficiency of the dewatering screen and solving the problem that the existing dewatering screen can only remove moisture alone and has limited use.

[0039] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 4The machine body 2 is equipped with a storage seat 23, on which a propulsion assembly 5 is installed. A spray assembly 3 is located between the propulsion assembly 5 and the extrusion assembly 4. When the material moves on the screen plate 21, it is first dispersed by the propulsion assembly 5 and then washed again by the spray assembly 3. Subsequently, the material is extruded by the extrusion assembly 4 to ensure the degree of dehydration. The propulsion assembly 5 includes a push rod component 51, which adopts an electric push rod, pneumatic push rod, or hydraulic push rod as used in the prior art. The piston end of the push rod component 51 passes through the storage seat 23 and is connected to a support plate 52. Several guide plate components 53 are provided on the support plate 52 at intervals along the length of the support plate 52. The spaced guide plate components 53 can... Multiple independent material pushing areas are formed. The guide plate component 53 includes a plate body 531. With the cooperation of the push rod component 51, the plate body 531 is oriented towards or away from the screen plate 21. When the material is located on the screen plate 21 and moves, it first contacts the plate body 531 in the push assembly 5. The contact between the plate body 531 and the material can beat the material on the screen plate 21 to disperse it, thereby avoiding the accumulation of large pieces of material and thus affecting the dewatering effect. The guide plate component 53 is connected to the push rod component 51. Therefore, the support plate 52 is extended and retracted by the push rod component 51, thereby controlling the position of the guide plate component 53 and changing the position of the guide plate component 53 to achieve adjustment according to different material conditions.

[0040] The guide plate component 53 also includes a bearing seat 532, which is disposed on the support plate 52. A support rod 533 is installed on the bearing seat 532. The plate body 531 is provided with two sets of support rods 533 symmetrically distributed on both sides of the support rods 533. With the cooperation of the bearing seat 532, the support rods 533 can drive the plate body 531 to rotate in a circular motion. When the support rods 533 drive the plate body 531 to rotate in a circular motion with the cooperation of the bearing seat 532, a turning force can be applied to the material, breaking the compaction state of the material and exposing the impurities or moisture inside. At the same time, the rotation action can reduce the adhesion of the material on the surface of the plate body 531, avoiding the material residue problem caused by friction in traditional linear push plates and reducing the frequency of manual cleaning.

[0041] The plate 531 has several overflow holes 5311, which are evenly distributed on the plate 531. When the plate 531 pushes the material, the washing water and free water in the material can pass through the overflow holes 5311, which prevents the liquid from carrying the material to accumulate in front of the plate 531. At the same time, it can break up large pieces of accumulated material and improve the screening efficiency.

[0042] In one embodiment, reference is made to Figures 1-3The base 1 is equipped with a liquid collection tank 11, which is located below the sieve plate 21. The liquid collection tank 11 is used to collect the liquid filtered by the sieve plate 21. The machine body 2 is equipped with a return material box 24, which is connected to a hydrocyclone 25. The input end of the hydrocyclone 25 extends into the liquid collection tank 11 through a pipeline, and the output end of the hydrocyclone 25 faces the sieve plate 21. The hydrocyclone 25 uses centrifugal force to separate the liquid in the liquid collection tank 11 into solid and liquid, and re-transports the effective material to the sieve plate 21 to avoid material loss caused by direct discharge. At the same time, when the output end of the hydrocyclone 25 sprays material onto the sieve plate 21, the high-speed fluid can flush the surface of the sieve holes, reduce the retention of fine particles in the sieve holes, and reduce the risk of sieve plate blockage.

[0043] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 5 The machine body 2 is equipped with a flow divider plate 26, which is located below the output end of the hydrocyclone 25. The flow divider plate 26 has a protrusion 261, and inclined ends 2611 are provided on both sides of the protrusion 261. When the material output from the hydrocyclone 25 passes through the flow divider plate 26, the protrusion 261 divides the concentrated material flow into two streams, which diffuse to both sides along the inclined ends 2611, ensuring that the material evenly covers the entire width of the screen plate 21, avoiding local overload or uneven wear of the screen plate. The structural design of the protrusion 261 can break up small particle clumps that may be output from the hydrocyclone 25, preventing clumps from directly impacting the screen holes and causing blockage. At the same time, the flow divider plate 26 bears the main material impact load, playing a buffering role, protecting the screen plate 21 from high-speed fluid wear, and extending the screen plate life.

[0044] In one embodiment, reference is made to Figure 1 and Figure 2 A guide plate 27 is inclinedly provided at the end of the machine body 2 away from the extrusion component 4. One end of the guide plate 27 extends to the outside of the machine body 2. The inclined guide plate 27 uses gravity to assist the material movement, ensuring that the material after dewatering by the extrusion component 4 leaves the screen plate 21 quickly, avoiding material accumulation or backflow at the discharge end. At the same time, the smooth inclined surface reduces material adhesion.
