Description

Technical Field

[0001] The present invention relates to the technical field of material dehydration, and particularly to a centrifugal dehydrator. Background Art

[0002] The dehydrator, mostly referring to the centrifugal dehydrator, is mostly used for the centrifugal dehydration of materials in traditional industries. It utilizes the centrifugal force to rotate the inner tank and conducts high-speed rotation dehydration on the materials inside the inner tank.

[0003] In the prior art, traditional dehydration equipment generally sets a base and a motor at the bottom of the equipment, so that after each dehydration operation, it is necessary to manually take out the dehydrated materials from the top, which cannot perform automated and streamlined operations, resulting in low production efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a centrifugal dehydrator to solve the technical problems that the dehydration equipment in the prior art cannot perform automated and streamlined operations and has low production efficiency.

[0005] The present invention provides a centrifugal dehydrator, including a centrifugal inner barrel, a centrifugal outer barrel and a transmission mechanism. The bottom of the centrifugal inner barrel is provided with small holes and is embedded in the centrifugal outer barrel and is concentric with the centrifugal outer barrel. The transmission mechanism is arranged directly above the centrifugal inner barrel, is fixed to the centrifugal inner barrel, and drives the centrifugal inner barrel to rotate in the centrifugal outer barrel. The center of the transmission mechanism is set as a feed inlet. The bottom of the centrifugal inner barrel is detachably embedded with an inner barrel bottom cover. A spiral wire groove and a guide pin are concentrically arranged inside the inner barrel bottom cover, and the guide pins are circumferentially arrayed and embedded on the surface of the spiral wire groove. A support frame is arranged directly below the centrifugal inner barrel. A bottom cover engaging structure is slidably connected to the surface of the support frame through a bottom cover transverse movement structure. The bottom cover engaging structure can drive the engagement of the inner barrel bottom cover and the centrifugal inner barrel in a liftable manner. In the prior art, traditional dehydration equipment generally sets a base and a motor at the bottom of the equipment, so that after each dehydration operation, it is necessary to manually take out the dehydrated materials from the top, which cannot perform automated and streamlined operations, resulting in low production efficiency. In response to such problems, this product is designed to feed materials from the top and discharge materials automatically from the bottom, and the transmission mechanism is arranged at the top of the equipment, which can achieve high-efficiency automated and streamlined operations.

[0006] Further, the bottom cover transverse movement structure includes a guide rail fixed to the support frame. The surface of the guide rail drives the bottom cover transverse movement structure to slide on the surface of the guide rail through a synchronous pulley, a synchronous belt, and a bottom cover transverse movement motor. It also includes a bottom cover switch board and a placement groove, and the bottom cover switch board is arranged on the top surface of the placement groove. A transverse positive limit trigger piece and a transverse negative limit trigger piece are fixed on the side surface of the placement groove. Transverse positive limit sensors and transverse negative limit sensors are respectively arranged at both ends of the guide rail. When the inner barrel bottom cover is directly below the centrifugal inner barrel, the transverse positive limit sensor contacts the transverse positive limit trigger. In this product, when the inner barrel bottom cover can be transversely moved to directly below the centrifugal inner barrel along with the bottom cover switch board, the transverse positive limit sensor and the transverse positive limit trigger are triggered, thereby preventing the inner barrel bottom cover from being overly transversely moved, and then driving the bottom cover clamping structure to raise the bottom cover switch board and clamp the inner barrel bottom cover.

[0007] Further, the bottom cover clamping structure includes a bevel gear arranged on the top surface of the bottom cover switch board. A conical tooth is correspondingly and penetratingly opened at the center of the inner barrel bottom cover, and the conical tooth fits with the bevel gear correspondingly. A rotating motor is arranged at the bottom of the bottom cover switch board, and the rotating motor drives the bevel gear to rotate. A planetary gear set is arranged in the placement groove. The planetary gear set is used to drive the lifting screw rod to lift and lower, and the upper end of the lifting screw rod is rotatably fixed to the bottom cover switch board. The planetary gear set is driven to rotate by a lifting motor, and the lifting motor is fixed to the bottom of the placement groove. In this product, after the inner barrel bottom cover is transversely moved to directly below the centrifugal inner barrel through the bottom cover transverse movement structure, the lifting motor drives the planetary gear set and the lifting screw rod to lift the bottom cover switch board and the inner barrel bottom cover, so that the inner barrel bottom cover and the centrifugal inner barrel fit. Then, the rotating motor drives the conical tooth to rotate. Since the conical tooth meshes with the guide pin inside the inner barrel bottom cover, the guide pin rotates together with the conical tooth, and will rotate in the spiral groove, and the guide pin will extend outwards, so as to be clamped into the inner barrel card slot to achieve fixation, thereby realizing the automatic clamping or opening of the inner barrel bottom cover.

[0008] Further, magnets are arrayed and fixed on the top surface of the bottom cover switch board. After the centrifugal dehydration is completed and the bottom cover switch board rises to receive the inner barrel bottom cover, in order to prevent the inner barrel bottom cover from not being able to fall with the bottom cover switch board due to friction, magnets are designed to adsorb the inner barrel bottom cover, so that the inner barrel bottom cover can fall together with the bottom cover switch board.

[0009] Further, an inner barrel card slot is opened at the bottom of the centrifugal inner barrel, and the centrifugal inner barrel is detachably installed with the inner barrel bottom cover through the inner barrel card slot.

[0010] Further, the transmission mechanism includes a rotating bracket fixed to the top of the centrifugal inner barrel. The rotating bracket is driven to rotate by a transmission motor through a transmission pulley and a transmission belt, and the transmission pulley is rotationally connected to the feed port through a bearing.

[0011] Further, inner barrel buckles are fixedly arranged in a circumferential array at the top of the centrifugal inner barrel, and the centrifugal inner barrel is fixed to the rotating bracket through the inner barrel buckles.

[0012] Further, the centrifugal outer barrel includes an outer barrel wall, and the outer barrel wall is made of a flexible material. Outer barrel brackets are arranged in a circumferential array around the centrifugal inner barrel, and the outer barrel wall is embedded in the outer barrel brackets.

[0013] Further, an outer barrel drain port is opened at the bottom of the centrifugal outer barrel, and a cleaning scraper is fixed at the bottom of the centrifugal outer barrel. After a round of centrifugal dehydration is completed, when discharging materials from the bottom and retracting the inner barrel bottom cover, when the inner barrel bottom cover moves horizontally, the cleaning scraper can scrape off the dirt staying on the surface of the inner barrel bottom cover, avoiding the dirt from affecting the sealing of the inner barrel bottom cover.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] First, in the prior art, traditional dehydration equipment generally sets a base and a motor at the bottom of the equipment, so that after each dehydration operation, it is necessary to manually take out the dehydrated materials from the top, and it is impossible to perform automated and streamlined operations, resulting in low production efficiency. In view of such problems, this product is designed to feed materials from the top and discharge materials automatically from the bottom, and the transmission mechanism is arranged at the top of the equipment, which can realize high-efficiency automated and streamlined operations.

[0016] Second, in the present invention, when the inner barrel bottom cover can be horizontally moved to directly below the centrifugal inner barrel along with the bottom cover switch board, the horizontal positive limit sensor and the horizontal positive limit trigger are triggered, thereby preventing the inner barrel bottom cover from being horizontally moved excessively, and then driving the bottom cover clamping structure to raise the bottom cover switch board and clamp the inner barrel bottom cover.

[0017] Third, in the present invention, after the inner barrel bottom cover is horizontally moved to directly below the centrifugal inner barrel through the bottom cover horizontal movement structure, the jacking motor drives the planetary gear set and the jacking screw rod to jack up the bottom cover switch board and the inner barrel bottom cover, so that the inner barrel bottom cover fits with the centrifugal inner barrel. Then, the rotating motor drives the conical gear to rotate. Since the conical gear meshes with the guiding pins inside the inner barrel bottom cover, the guiding pins rotate together with the conical gear, and will rotate in the spiral wire groove, and the guiding pins will extend outwards, so as to be clamped into the inner barrel clamping groove to achieve fixation, thereby realizing the automatic clamping or opening of the inner barrel bottom cover.

[0034] The following is combined with Figures 1 to 8As shown in the figure, an embodiment of the present invention provides a centrifugal dehydrator, which includes a centrifugal inner barrel 3, a centrifugal outer barrel 4, and a transmission mechanism 2. A small hole is opened at the bottom of the centrifugal inner barrel 3, and it is embedded in the centrifugal outer barrel 4 and is concentric with the centrifugal outer barrel 4. The transmission mechanism 2 is arranged directly above the centrifugal inner barrel 3, is fixed to the centrifugal inner barrel 3, and drives the centrifugal inner barrel 3 to rotate in the centrifugal outer barrel 4. The center of the transmission mechanism 2 is set as a feed inlet 1. The transmission mechanism 2 includes a rotating bracket 205 fixed to the top of the centrifugal inner barrel 3. The rotating bracket 205 is driven to rotate by a transmission pulley 201 and a transmission belt 202 through a transmission motor 203. The transmission pulley 201 is rotatably connected to the feed inlet 1 through a bearing 204; a plurality of inner barrel buckles 302 are fixedly arranged in a circumferential array at the top of the centrifugal inner barrel 3, and the centrifugal inner barrel 3 is fixed to the rotating bracket 205 through the inner barrel buckles 302. The centrifugal outer barrel 4 includes an outer barrel wall 401, and the outer barrel wall 401 is made of a flexible material. A plurality of outer barrel supports 402 are arranged in a circumferential array around the centrifugal inner barrel 3, and the outer barrel wall 401 is embedded in the outer barrel supports 402; a detachable inner barrel bottom cover 6 is embedded at the bottom of the centrifugal inner barrel 3. A spiral wire groove 601 and a guide pin 602 are concentrically arranged inside the inner barrel bottom cover 6, and the guide pin 602 is circumferentially arrayed and embedded on the surface of the spiral wire groove 601. A support frame 10 is arranged directly below the centrifugal inner barrel 3. A bottom cover engaging structure 8 is slidably connected to the surface of the support frame 10 through a bottom cover transverse movement structure 7. The bottom cover transverse movement structure 7 includes a guide rail 705 fixed to the support frame 10. The surface of the guide rail 705 drives the bottom cover transverse movement structure 7 to slide on the surface of the guide rail 705 through a synchronous pulley 703, a synchronous belt 704, and a bottom cover transverse movement motor 702. It also includes a bottom cover switch plate 701 and a placement groove 710. The bottom cover switch plate 701 is arranged on the top surface of the placement groove 710. A transverse positive limit trigger piece 707 and a transverse negative limit trigger piece 709 are fixed to the side surface of the placement groove 710. Transverse positive limit sensors 706 and transverse negative limit sensors 708 are respectively arranged at both ends of the guide rail 705. When the inner barrel bottom cover 6 is directly below the centrifugal inner barrel 3, the transverse positive limit sensor 706 contacts the transverse positive limit trigger. In this product, when the inner barrel bottom cover 6 can be horizontally moved to directly below the centrifugal inner barrel 3 along with the bottom cover switch plate 701, the transverse positive limit sensor 706 and the transverse positive limit trigger are triggered, thereby preventing the inner barrel bottom cover 6 from being excessively horizontally moved, and then driving the bottom cover engaging structure 8 to lift the bottom cover switch plate 701 and engage the inner barrel bottom cover 6;The bottom cover engaging structure 8 enables the engagement of the liftable bottom cover 6 of the ground-driven inner barrel with the centrifugal inner barrel 3. The bottom cover engaging structure 8 includes a bevel gear 805 disposed on the top surface of the bottom cover switch board 701. A tapered tooth 806 is correspondingly and penetratively formed at the center of the inner barrel bottom cover 6, and the tapered tooth 806 is correspondingly fitted with the bevel gear 805. A rotary motor 804 is disposed at the bottom of the bottom cover switch board 701, and the rotary motor 804 drives the bevel gear 805 to rotate. A planetary gear set 802 is disposed in the placement groove 710. The planetary gear set 802 is used to drive the lifting screw rod 803 to lift and lower, and the upper end of the lifting screw rod 803 is rotatably fixed to the bottom cover switch board 701. The planetary gear set 802 is driven to rotate by a lifting motor 801, and the lifting motor 801 is fixed to the bottom of the placement groove 710.;

[0035] In this product, after the inner barrel bottom cover 6 is horizontally moved to directly below the centrifugal inner barrel 3 through the bottom cover horizontal movement structure 7, the lifting motor 801 drives the planetary gear set 802 and the lifting screw rod 803 to lift the bottom cover switch board 701 and the inner barrel bottom cover 6, so that the inner barrel bottom cover 6 and the centrifugal inner barrel 3 are fitted. Then, the rotary motor 804 drives the tapered tooth 806 to rotate. Since the tapered tooth 806 meshes with the guiding pin 602 inside the inner barrel bottom cover 6, the guiding pin 602 rotates together with the tapered tooth 806, and will rotate in the spiral wire groove 601, and the guiding pin 602 will extend outwards, so as to be clamped into the inner barrel clamping groove 301 to achieve fixation. The bottom of the centrifugal inner barrel 3 is provided with an inner barrel clamping groove 301, and the centrifugal inner barrel 3 is detachably installed with the inner barrel bottom cover 6 through the inner barrel clamping groove 301, so as to realize the automatic engagement or opening of the inner barrel bottom cover 6; at the same time, after the inner barrel bottom cover 6 is engaged, the structure for lifting will cause the bottom cover switch board 701 to fall. At this time, the inner barrel bottom cover 6 and the centrifugal inner barrel 3 are integrated and rotate together during rotation, while the bottom cover switch board 701 and a series of components inside it have separated and will not rotate together, thus preventing the bottom cover switch board 701 from accidentally not detaching from the inner barrel bottom cover 6, causing the inner barrel bottom cover 6 and the centrifugal inner barrel 3 to be non-concentric during the rotation of the centrifugal inner barrel 3 and resulting in the damage of the lifting screw rod 803, avoiding the occurrence of such failures. It not only realizes the function, but also can greatly improve the reliability and stability of the mechanism. In the prior art, traditional dehydration equipment generally sets a base and a motor at the bottom of the equipment, so that after each dehydration operation, it is necessary to manually take out the dehydrated materials from the top, and it cannot perform automatic and streamlined operations, with low production efficiency. In view of such problems, this product is designed with a top-feed and bottom-automatic-discharge method, and the transmission mechanism 2 is disposed at the top of the equipment, which can realize high-efficiency automatic and streamlined operations.

[0036] In another embodiment, magnets 807 are fixed in an array on the top surface of the bottom cover switch plate 701. After centrifugal dehydration is completed, the bottom cover switch plate 701 rises, and when the inner barrel bottom cover 6 is taken down, in order to prevent the friction from causing the inner barrel bottom cover 6 to be unable to fall with the bottom cover switch plate 701, the magnets 807 are designed to adsorb the inner barrel bottom cover 6 so that the inner barrel bottom cover 6 can fall together with the bottom cover switch plate 701.

[0037] In another embodiment, an outer barrel drain port 5 is opened at the bottom of the centrifugal outer barrel 4, and a cleaning scraper 9 is fixed to the bottom of the centrifugal outer barrel 4. After a round of centrifugal dehydration is completed, when the bottom is discharged, when the inner barrel bottom cover 6 is folded up, the cleaning scraper 9 can scrape off the dirt remaining on the surface of the inner barrel bottom cover 6 when the inner barrel bottom cover 6 moves horizontally, so as to prevent the dirt from affecting the sealing of the inner barrel bottom cover 6.

[0038] Working principle of the present invention: In this product, the inner barrel bottom cover 6 is transversely moved to the transverse positive limit sensor 706 under the action of the bottom cover transverse movement motor 702, the synchronous pulley 703, the synchronous belt 704 and the guide rail 705, and then the lifting motor 801 rotates, driving the planetary gear set 802 and the lifting screw 803 to lift the bottom cover switch plate 701. When the bottom cover switch plate 701 is lifted into place, the conical teeth 806 cooperate with the bevel gear 805, and the rotating motor 804 rotates, driving the inner barrel bottom cover 6 and the spiral groove 601 to rotate, and the guide pin 602 extends outward and is stuck in the inner barrel slot 301. After ensuring that the inner barrel bottom cover 6 is combined with the centrifugal inner barrel 3, the lifting motor 801 reverses, driving the planetary gear set 802 to reverse accordingly, and the lifting screw 803 descends, and the bottom cover switch plate 701 is separated from the inner barrel bottom cover 6. During centrifugal dehydration, the inner barrel bottom cover 6 will rotate together with the centrifugal inner barrel 3.

[0039] At this time, the material is put into the feed port 1, the inner barrel buckle 302 fastens the centrifugal inner barrel 3 and the rotating bracket 205, the transmission motor 203 rotates, and under the transmission of the transmission pulley 201, the transmission belt 202 and the bearing 204, the rotating bracket 205 drives the centrifugal inner barrel 3 to rotate, and the water will be thrown into the centrifugal outer barrel 4 through the holes of the centrifugal inner barrel 3, and the centrifugal outer barrel 4 will block the water and divert it to the outer barrel drain port 5.

[0040] After the centrifugal dehydration is completed, the bottom cover clamping structure 8 repeats the jacking step to lift the bottom cover switch plate 701. The rotation motor 804 retracts the guiding pin 602, and the magnet 807 attracts the inner barrel bottom cover 6. Then, the jacking motor 801, the planetary gear set 802, and the jacking lead screw 803 flip to lower the inner barrel bottom cover 6 to a certain height. The bottom cover clamping structure 8 controls the lateral movement of the inner barrel bottom cover 6. When the inner barrel bottom cover 6 moves laterally, the cleaning scraper 9 scrapes off the dirt remaining on the surface of the inner barrel bottom cover 6 to prevent the dirt from affecting the bottom cover seal. After the inner barrel bottom cover 6 is opened, the materials in the centrifugal inner barrel 3 fall down by their weight and enter the next process, thus realizing centrifugal dehydration and achieving an automated and streamlined operation process.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
