Description

Technical Field

[0001] This invention relates to the field of vibrating screen technology, and specifically to a triaxial elliptical vibrating screen with anti-clogging holes. Background Technology

[0002] A triaxial elliptical vibrating screen is a device used for screening materials. It mainly consists of three axial vibrators, which can realize the movement of materials horizontally, vertically, and obliquely. When separating materials, after the materials enter the equipment, they are evenly distributed to the three axial vibrators through the feed inlet. The vibration frequency and amplitude of each axial vibrator can be adjusted according to different material characteristics and process requirements. Under the action of the three axial vibrators, the materials will be subjected to different degrees of vibration and impact, thereby causing the different components in the materials to separate. Lighter materials will be screened out and move upward along the vibrating screen, ultimately achieving the purpose of separation. The separated materials will be discharged through the discharge outlet.

[0003] If the screen of a triaxial elliptical vibrator becomes clogged during operation, it will affect the normal operation of the equipment and may even damage equipment parts. Therefore, it is necessary to pay attention to whether the screen is working properly. If the screen of the triaxial elliptical vibrator becomes clogged, the material cannot be screened out in time, which will affect the production capacity of the equipment and reduce the output. At the same time, screen clogging will increase the wear of the screen holes, which will lead to excessive wear of equipment parts in the long run, thereby affecting the service life of the equipment and increasing the maintenance and repair costs.

[0062] A connecting pipe is provided between the drain pipe and the output end of the water pump.

[0063] The working principle and beneficial effects of this invention are as follows:

[0064] 1. In this invention, the eccentric wheel is first fitted onto the fixed cylinder according to requirements. Then, the fixed outer shell is inserted into the end of the fixed cylinder until the end of the fixed outer shell contacts the eccentric wheel, and at the same time, the eccentric wheel contacts the fixed ring. At this point, the fixing screw is screwed into the fixing nut. Through the setting of the fixed outer shell and the fixed ring, the eccentric wheel is firmly fixed to the fixed cylinder, and the eccentric wheel does not rotate relative to the fixed cylinder. At this time, the fixed cylinder can be driven to rotate by the rotating frame, and the fixed cylinder drives the eccentric wheel to rotate. Through the cooperation between the coupling, the transmission shaft and the transmission gear, multiple eccentric wheels can be driven to rotate simultaneously, thereby applying vibration to the vibration box. When it is necessary to adjust the vibration frequency of the vibration box, it is only necessary to unscrew the corresponding fixing screw and adjust the position of the corresponding eccentric wheel, which improves the working efficiency.

[0065] 2. In this invention, the second motor drives the cam to rotate, and the rotation of the cam drives the pressure plate to move. When the cam contacts the pressure plate at its maximum radius, the second spring is in a compressed state. When the cam rotates past the maximum radius, the second spring releases the pressure, thereby driving the pressure plate to move quickly, which in turn drives the impact rod to strike the screen plate until the cam contacts the pressure plate again, realizing the periodic impact on the screen plate, thereby shaking down the material stuck on the screen plate and improving the screening efficiency.

[0066] 3. In this invention, the water pump draws water from the water tank and then discharges the water into the connecting pipe. The connecting pipe discharges the water into the drain pipe. When the drain pipe is full of water, the spray nozzle is activated to spray the material, thereby reducing dust generation during the screening process and improving work safety.

[0067] 4. In this invention, the vibration frequency of the vibrating box can be quickly adjusted by setting up the vibration component and the shock absorption component, so that the equipment can cope with the screening of different materials, improving the screening efficiency and quality. Moreover, the vibration of the vibrating box can also reduce the impact of the vibration of the vibrating box on the overall stability of the equipment during the screening process. By setting up the anti-clogging component and the water spray component, the possibility of material getting stuck on the screen plate during the screening process is reduced, so that the material can be screened out in time, improving the screening effect and thus improving the screening efficiency.

Detailed Implementation

[0082] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0083] like Figures 1 to 12 As shown, this embodiment proposes a triaxial elliptical vibrating screen with anti-clogging holes, including a base plate 1, a mounting frame 2, a shock absorption assembly, a vibrating box 3, a screening assembly, a vibrating assembly, an anti-clogging assembly, and a water spray assembly. The mounting frame 2 is fixedly mounted on the base plate 1, the shock absorption assembly is mounted on the mounting frame 2, and the vibrating box 3 is mounted on the shock absorption assembly. The shock absorption assembly is used to reduce the vibration of the vibrating box 3 during operation. The shock absorption assembly includes columns 4, first springs 5, and load-bearing frames 6. Two columns 4 are symmetrically and fixedly mounted on both sides of the upper part of the mounting frame 2, and first springs 5 ​​are fixedly mounted on the top of each of the four columns 4. Load-bearing frames 6 are symmetrically and fixedly mounted on both sides of the vibrating box 3, and the four load-bearing frames 6 correspond one-to-one with the four columns 4. The load-bearing frames 6 are fixedly connected to the first springs 5.

[0084] Specifically, when materials need to be screened, the materials are first poured into the vibrating chamber 3, and the vibration component is started. The vibration component applies vibration to the vibrating chamber 3, and the vibration of the vibrating chamber 3 drives the screening component to vibrate, thereby screening the materials. During the screening process, the water spray component is activated to spray water onto the materials entering the vibrating chamber 3, thereby reducing the possibility of dust generation during screening and improving work safety. During the screening process, in order to prevent materials from clogging the screening component, the anti-clogging component is activated, and the screening component is periodically impacted, thereby shaking down the materials that are blocked in the screening component through inertial force, thus reducing the possibility of blockage. At the same time, as the vibrating chamber 3 vibrates, the vibrating chamber 3 drives the load frame 6 to vibrate. The setting of the first spring 5 can effectively eliminate the possibility of the vibration of the vibrating chamber 3 being transmitted to the bottom plate 1, preventing the vibration from being transmitted to the ground and causing resonance, thus improving the safety during use.

[0085] like Figure 3 , Figure 5 As shown, the screening assembly is installed inside the vibrating box 3 for screening materials. The screening assembly includes a screen plate 7, a feed hopper 8, a discharge hopper 9, and a waste port 10. The screen plate 7 is fixedly installed inside the vibrating box 3. The feed hopper 8 is fixedly installed at the feed end of the vibrating box 3 and is located above the screen plate 7. The discharge hopper 9 is fixedly installed at the discharge end of the vibrating box 3 and is located above the screen plate 7. A waste port 10 is provided at the bottom of the discharge end of the vibrating box 3.

[0086] Specifically, when screening materials, the materials are first poured into the vibrating box 3 from the feed hopper 8. At this time, the materials are on the screen plate 7. As the vibrating box 3 vibrates, the screen plate 7 vibrates, thereby screening the materials. The broken materials will enter the bottom of the vibrating box 3 for storage. As screening continues, the materials will move towards the discharge port. At this time, the screened materials will be discharged through the discharge hopper 9. After working for a period of time, the waste port 10 is opened to clean out the broken materials.

[0087] like Figures 5 to 9 As shown, the vibration assembly is installed on the vibration box 3 to apply vibration to the vibration box 3. The vibration assembly includes a mounting shell 11, transmission gears 12, rotating frames 13, protective shells 14, a drive unit, and a vibration unit. Mounting shells 11 are fixedly installed on both sides of the vibration box 3. Three transmission gears 12 are equidistantly and rotatably installed inside the two mounting shells 11. Each pair of adjacent transmission gears 12 in each mounting shell 11 meshes with each other. A rotating frame 13 is fixedly installed on each transmission gear 12 and is rotatably connected to the mounting shell 11. A protective shell 14 can be detachably installed at the end of each rotating frame 13. The drive unit is installed on the base plate 1 and is used to drive multiple rotating frames 13 to rotate simultaneously. A vibration unit is installed inside the rotating frame 13 to apply vibration to the vibration box 3.

[0088] Specifically, when applying vibration to the vibration chamber 3, the start-up drive unit drives one of the rotating frames 13 to rotate. Through the setting of the transmission gear ring, all the rotating frames 13 can be driven to rotate in the mounting shell 11 at the same time, thereby driving the vibration unit to rotate and applying vibration to the vibration chamber 3. Through the setting of the protective shell 14, the vibration unit can be protected from interference during operation, and the safety of the staff is also improved.

[0089] The above, such as Figure 7 As shown, the drive unit includes a first motor 15, a driving pulley 16, a driven pulley 17, and a transmission belt 18. The first motor 15 is fixedly mounted on the base plate 1, the driving pulley 16 is fixedly mounted on the output end of the first motor 15, the driven pulley 17 is fixedly mounted on one of the rotating frames 13, and the transmission belt 18 is tensioned and sleeved between the driving pulley 16 and the driven pulley 17.

[0090] Specifically, when the rotating frame 13 is rotated, the first motor 15 is started. The first motor 15 drives the driving pulley 16 to rotate. The driving pulley 16 drives the driven pulley 17 to rotate through the transmission belt 18, thereby driving one of the rotating frames 13 to rotate. Through the setting of the transmission gear 12, multiple rotating frames 13 can be driven to rotate simultaneously.

[0091] The above, such as Figure 8 , Figure 9As shown, the vibrating part includes a fixed cylinder 19, a fixed ring 20, a fixed housing 21, an eccentric wheel 22, a fixing screw 23, a fixing nut 24, a coupling 25, and a drive shaft 26. Each rotating frame 13 has a fixed cylinder 19 fixedly installed inside, a fixed ring 20 fixedly installed on each fixed cylinder 19, a fixed housing 21 slidably installed on each fixed cylinder 19, an eccentric wheel 22 fitted on each fixed cylinder 19, the eccentric wheel 22 being located between the fixed ring 20 and the fixed housing 21, a fixing screw 23 rotatably installed on each fixed housing 21, a fixing nut 24 threaded onto each fixing screw 23, the fixing nut 24 being fixedly connected to the fixed cylinder 19, a coupling 25 fixedly installed at the end of each fixed cylinder 19, and a drive shaft 26 fixedly installed between every two couplings 25.

[0092] Specifically, before applying vibration to the vibration chamber 3, the eccentric wheel 22 is first fitted onto the fixed cylinder 19 as required. Then, the fixed outer shell 21 is inserted into the end of the fixed cylinder 19 until the end of the fixed outer shell 21 contacts the eccentric wheel 22, and at the same time, the eccentric wheel 22 contacts the fixed ring 20. At this time, the fixing screw 23 is screwed into the fixing nut 24. Thus, through the setting of the fixed outer shell 21 and the fixed ring 20, the eccentric wheel 22 is firmly fixed on the fixed cylinder 19, and the eccentric wheel 22 does not rotate relative to the fixed cylinder 19. At this time, the fixed cylinder 19 can be driven to rotate by the rotating frame 13, and the fixed cylinder 19 drives the eccentric wheel 22 to rotate. Through the cooperation between the coupling 25, the transmission shaft 26 and the transmission gear 12, multiple eccentric wheels 22 can be driven to rotate simultaneously, thereby applying vibration to the vibration chamber 3.

[0093] like Figure 10 , Figure 11 As shown, the anti-clogging component is installed inside the vibrating box 3 to prevent the screening component from clogging during the material screening process. The anti-clogging component includes a support frame 27, an impact rod 28, a pressure plate 29, and a power unit. Multiple support frames 27 are fixedly installed at equal intervals inside the vibrating box 3. The support frames 27 are located on the upper part of the screen plate 7. An impact rod 28 is slidably installed on each support frame 27. A pressure plate 29 is fixedly installed on the top of each impact rod 28. The pressure plate 29 slides with the support frame 27. The power unit is installed on the support frame 27 to drive the impact rod 28 to move back and forth.

[0094] Specifically, during the screening process, in order to prevent the material from clogging the screen holes of the screen plate 7 and affecting the screening efficiency, the power unit is started. The power unit drives the pressure plate 29 to move periodically. During the movement, the impact rod 28 continuously applies impact force to the screen plate 7, thereby shaking the material stuck on the screen plate 7 off through the inertial force of the material.

[0095] The above, such as Figure 11As shown, the power unit includes a second motor 30, a cam 31, and a second spring 32. A second motor 30 is fixedly installed on each support frame 27, and a cam 31 is rotatably installed inside each support frame 27. The cam 31 is fixedly connected to the output end of the second motor 30. A second spring 32 is fixedly installed on the top of each pressure plate 29 and is fixedly connected to the inner top wall of the support frame 27.

[0096] Specifically, when the pressure plate 29 is moved, the second motor 30 is started. The second motor 30 drives the cam 31 to rotate. The rotation of the cam 31 drives the pressure plate 29 to move. When the maximum radius of the cam 31 contacts the pressure plate 29, the second spring 32 is in a compressed state. When the cam 31 rotates past the maximum radius, the second spring 32 releases the pressure, thereby driving the pressure plate 29 to move quickly, thereby driving the impact rod 28 to strike the screen plate 7 until the cam 31 contacts the pressure plate 29 again. Repeating the above steps can achieve periodic impact on the screen plate 7, thereby shaking off the material stuck on the screen plate 7.

[0097] like Figure 12 As shown, the water spraying assembly is installed on the base plate 1 and is used to spray water on the material during the screening process. The water spraying assembly includes a water tank 33, a water pump 34, a support frame 35, and a water spraying part. The water tank 33 is fixedly installed on the base plate 1, the water pump 34 is fixedly installed on the water tank 33, and the input end of the water pump 34 is connected to the water tank 33. The support frame 35 is fixedly installed on the top of the vibrating box 3 and is located close to the feed hopper 8. The water spraying part is installed inside the support frame 35 for spraying water.

[0098] Specifically, when screening materials, it is also necessary to reduce the dust generated during the screening process. At this time, the water pump 34 is started to draw water from the water tank 33 and then discharge the water into the spray unit. The spray unit is then started to spray water onto the materials during the screening process.

[0099] The above, such as Figure 12 As shown, the water spray unit includes a drain pipe 36, a nozzle 37, and a connecting pipe 38. The drain pipe 36 is fixedly installed inside the support frame 35. Multiple nozzles 37 are connected to the drain pipe 36 at equal angles. The drain pipe 36 is connected to the output end of the water pump 34 by a connecting pipe 38.

[0100] Specifically, the water pump 34 discharges water into the connecting pipe 38, and the connecting pipe 38 discharges water into the drain pipe 36. When the drain pipe 36 is full of water, the spray nozzle 37 is activated to spray the material, thereby reducing the dust phenomenon that occurs during the screening process.

[0101] In summary, when materials need to be screened, the materials are first poured into the vibrating box 3 from the feed hopper 8. At this time, the materials are on the screen plate 7. Then, the first motor 15 is started, which drives the drive pulley 16 to rotate. The drive pulley 16 drives the driven pulley 17 to rotate through the transmission belt 18, thereby driving one of the rotating frames 13 to rotate. Through the cooperation between the coupling 25, the transmission shaft 26 and the transmission gear 12, multiple rotating frames 13 are driven to rotate simultaneously. The rotating frames 13 drive the fixed cylinder 19 to rotate, and the fixed cylinder 19 drives the eccentric wheel 22 to rotate. Thus, multiple eccentric wheels 22 can be driven to rotate simultaneously, thereby applying vibration to the vibrating box 3. The protective shell 14 can protect the vibrating part from interference during operation and also improve the safety of the staff.

[0102] As the vibrating box 3 vibrates, the screen plate 7 vibrates, thereby screening the material. The broken material will enter the bottom of the vibrating box 3 and be stored. As screening continues, the material will move towards the discharge port. At this time, the screened material will be discharged through the discharge hopper 9. After working for a period of time, the waste port 10 can be opened to clean out the broken material.

[0103] During the material screening process, it is also necessary to reduce the dust generated during screening. At this time, the water pump 34 is started to draw water from the water tank 33. Then the water pump 34 discharges the water into the connecting pipe 38, and the connecting pipe 38 discharges the water into the drain pipe 36. When the drain pipe 36 is full of water, the spray nozzle 37 is started to spray the material, thereby reducing the dust generated during screening and improving the safety of the operation.

[0104] During the screening process, to prevent material from clogging the screen plate 7 and affecting screening efficiency, the second motor 30 is started. The second motor 30 drives the cam 31 to rotate, which in turn drives the pressure plate 29 to move. When the maximum radius of the cam 31 contacts the pressure plate 29, the second spring 32 is compressed. After the cam 31 rotates past the maximum radius, the second spring 32 releases pressure, thereby driving the pressure plate 29 to move quickly, which in turn drives the impact rod 28 to strike the screen plate 7 until the cam 31 contacts the pressure plate 29 again. By repeating the above steps, the screen plate 7 can be periodically impacted, and the material stuck on the screen plate 7 can be shaken off by the inertial force of the material.

[0105] At the same time, as the vibration box 3 vibrates, the vibration box 3 drives the load frame 6 to vibrate. With the setting of the first spring 5, the possibility of the vibration of the vibration box 3 being transmitted to the bottom plate 1 can be effectively eliminated, preventing the vibration from being transmitted to the ground and causing resonance, thus improving the safety during use.

[0106] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
