Description

Technical Field

[0001] This utility model relates to the field of dewatering screen technology, and in particular to an energy-saving and environmentally friendly dewatering screen. Background Technology

[0002] Dewatering screens are mainly used for dewatering, desliming, and demediuming. They can be used for washing sand in sand and gravel plants, recovering coal slime in coal preparation plants, and dry discharge of tailings in mineral processing plants. Therefore, they are also called sand and gravel dewatering screens, mining dewatering screens, coal slime dewatering screens, and tailings dewatering screens.

[0003] Existing dewatering screens use high-power vibration sources to drive the screen frame to vibrate, which in turn causes the material on the screen plate to vibrate, thus achieving material screening. Although this can achieve a good screening effect, the high-power vibrator consumes a lot of energy and generates a lot of noise. The screened water is diverted through the guide plate below the screen frame, but the water contains a lot of dirt, which is inconvenient for workers to clean. Over time, the water accumulates, emits a foul odor, and causes many problems.

[0004] Therefore, this application provides an energy-saving and environmentally friendly dewatering screen to meet the requirements. Utility Model Content

[0005] The purpose of this application is to provide an energy-saving and environmentally friendly dewatering screen, which aims to solve the problems of high energy consumption and inconvenient cleaning of existing dewatering screens during use.

The material distribution assembly diverts the material during screening, thereby improving screening efficiency; by adopting a separate structure for the screen frame and the guide plate, the mass to be vibrated by the vibrator during operation is reduced, thereby reducing the energy consumed by the vibrator during operation, and the material distribution assembly is set on the screen frame to divert the material to be screened, ensuring the dewatering rate under the premise of low energy consumption, thus playing an energy-saving role;

[0007] A flow guide plate is mounted on the base via a support. The flow guide plate is located below the sieve plate and is used to guide the water separated from the material. A cleaning component is also provided on the flow guide plate.

[0008] Preferably, the material distribution assembly includes a diverting rod and a connecting beam. The connecting beam is installed on the screen frame.

[0009] Preferably, the diverting rod includes a mounting part and a diverting part. The mounting part is connected to the connecting beam by the bolts. The diverting part is provided with an arc-shaped surface, which corresponds to the feeding direction of the material.

[0010] Preferably, the cleaning assembly includes a scraper and a screw. The screw and a slide bar are respectively provided at the left and right ends of the diversion plate. The scraper is also slidably connected to the diversion plate. The scraper has threaded holes that mesh with the screw and sliding holes that match the slide bar at its left and right ends. A bidirectional motor that drives the screw to rotate is also installed on the diversion plate. Driven by the bidirectional motor, the scraper cleans the top surface of the diversion plate. The cleaning assembly on the diversion plate prevents dirt contained in the water from adhering to the diversion plate, thereby preventing the dirt from smelling bad and polluting the working environment, thus playing an environmental protection role.

[0011] Preferably, the front and rear sides of the diversion plate are provided with drain ports, and the scraper discharges the dirt on the diversion plate from the drain ports.

[0012] Preferably, both the sieve plate and the guide plate are inclined, and their inclination directions are opposite.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] In this invention, by adopting a separate structure for the screen frame and the diversion plate, the mass of vibration that the vibrator needs to drive during operation is reduced, thereby reducing the energy consumed by the vibrator during operation. A material distribution component is set on the screen frame to divert the material to be screened, ensuring the dehydration rate while using low energy consumption, thus achieving energy saving. A cleaning component is set on the diversion plate, which prevents dirt contained in the water from adhering to the diversion plate, thereby preventing dirt from odor and polluting the working environment, thus achieving an environmental protection effect.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0021] Example 1: Reference Figure 1-3 The present invention relates to an energy-saving and environmentally friendly dewatering screen, comprising a base 1 and a screen frame 2. The screen frame 2 is mounted on the base 1 via a spring seat 5. The screen frame 2 is provided with a vibrator 4 that drives it to vibrate. The screen frame 2 is also provided with a screen plate 6. The screen frame 2 is also provided with a multi-component material distribution assembly. The material distribution assembly divides the material in the screening process to improve the screening efficiency.

[0022] like Figure 2 As shown, the material distribution assembly includes a diverting rod 7 and a connecting beam 3. The connecting beam 3 is installed on the screen frame 2. The connecting beam 3 has multiple sets, and the diverting rod 7 is connected to the connecting beam 3 by bolts 8. The connecting beam 3 has multiple sets of bolt holes that mesh with the bolts 8. The diverting rod 7 has multiple sets and is arranged in an array on the connecting beam 3. The diverting rods 7 on adjacent connecting beams 3 are staggered.

[0023] The diverting rod 7 includes an installation part and a diverting part. The installation part is connected to the connecting beam 3 by the bolt 8. The diverting part is provided with an arc-shaped surface, which corresponds to the feeding direction of the material.

[0024] A flow guide plate 9 is installed on the base 1 via a support 11. The flow guide plate 9 is located below the sieve plate 6 and is used to guide the water separated from the material. The flow guide plate 9 is also equipped with a cleaning component.

[0025] like Figure 3As shown, the cleaning assembly includes a scraper 13 and a screw 12. The screw 12 and a slide bar 14 are respectively provided at the left and right ends of the diversion plate 9. The scraper 13 is also slidably connected to the diversion plate 9. The scraper 13 has threaded holes that mesh with the screw 12 and sliding holes that match the slide bar 14 at its left and right ends, respectively. A bidirectional motor 10 that drives the screw 12 to rotate is also installed on the diversion plate 9. Under the drive of the bidirectional motor 10, the scraper 13 slides on the upper surface of the diversion plate 9, and cleans the top surface of the diversion plate 9 at the same time.

[0026] The front and rear sides of the diversion plate 9 are provided with sewage outlets 15, and the scraper 13 discharges the dirt on the diversion plate 9 from the sewage outlets 15.

[0027] Both the sieve plate 6 and the guide plate 9 are inclined, and their inclination directions are opposite.

[0028] The working principle of this utility model is as follows: When in use, the equipment is connected to electricity and connected to an external PLC control center. The PLC control center controls the opening and closing of the electrical components in the equipment.

[0029] The vibrator 4 is controlled to work, which drives the screen frame 2 and screen plate 6 to vibrate. The material to be dewatered is put on the screen plate 6. Under the action of the vibration of the screen plate 6 and its own gravity, the material rolls along the screen plate 6, and the water is screened out. The material comes into contact with the diversion rod 7 on the connecting beam 3. The diversion rod 7 plays a role in pushing the material, causing the material to turn over and improve the dewatering rate.

[0030] Water falls from the sieve plate 6 onto the guide plate 9 and is collected under the guidance of the guide plate 9. At the same time, the water also contains a lot of dirt, which adheres to the guide plate 9 and cannot flow with the water. The bidirectional motor 10 is controlled to work, driving the screw 12 to rotate. The screw 12 engages with the thread on the scraper 13, and under the limit of the slide rod 14, it drives the scraper 13 to slide on the guide plate 9, thereby cleaning the dirt on the guide plate 9 and allowing the dirt to be discharged from the drain port 15 on the guide plate 9, preventing the accumulation of dirt and the emission of foul odors, thus achieving the purpose of environmental protection.
