Description

Technical Field

[0001] This utility model belongs to the field of ceramic processing technology, specifically a ceramic slurry constant temperature mixing and feeding device. Background Technology

[0002] The uniformity of ceramic slurry mixing directly determines the density, appearance smoothness, and finished product qualification rate of ceramic products. In large-scale ceramic production, constant temperature mixing and feeding equipment is a key piece of equipment connecting raw material preparation and molding processes. Its performance stability is crucial to the continuity of production. Therefore, there is an urgent need in the market for a constant temperature mixing and feeding equipment for ceramic slurry.

[0003] Most existing ceramic slurry constant temperature mixing and feeding equipment adopts a single-shaft mixing structure. The mixing blades are regularly distributed and in a single direction. During the mixing process, insufficient convection between the upper and lower layers of slurry is easily caused. High-viscosity slurry is prone to deposit at the bottom of the tank and adhere to the tank wall, resulting in poor slurry mixing uniformity.

[0004] Therefore, a ceramic slurry constant temperature mixing and feeding device is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a ceramic slurry constant temperature mixing and feeding device, which effectively avoids slurry deposition and wall adhesion, improves the uniformity of slurry mixing, and enables continuous scraping of the tank wall without dead corners, further reducing the slurry adhesion residue rate and ensuring the uniformity of slurry components during the feeding stage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ceramic slurry constant temperature mixing and feeding device, comprising a constant temperature chamber, a power motor fixedly connected to the top of the constant temperature chamber, an output shaft fixedly connected to the output end of the power motor passing through the top of the constant temperature chamber, a connecting frame rotatably connected to the outer surface of the output shaft, a drive gear fixedly connected to the bottom end of the output shaft passing through the connecting frame, two mirror-distributed driven gears meshing with the outer surface of the drive gear, the two driven gears meshing with the drive gear, and a gear ring meshing with the outer surface of the two driven gears, the gear ring being fixedly connected to the constant temperature chamber;

[0007] Both driven gears and the driving gear are fixedly connected to the bottom end of a stirring rod. Several stirring blades are fixedly connected to the outer surface of each of the three stirring rods. The outer surfaces of the three stirring rods are rotatably fitted with two mounting brackets. Both ends of the two mounting brackets are fixedly connected to elastic telescopic rods. The two elastic telescopic rods on the same vertical side are fixedly connected to a scraper.

[0008] Preferably, the stirring blades on the bottom stirring rods of the two driven gears are staggered with the stirring blades on the bottom stirring rod of the driving gear, and the horizontal projections of two adjacent stirring blades do not overlap.

[0009] Preferably, the stirring blades on the stirring rod at the bottom of the driven gear are inclined, and the stirring blades on the upper side of the stirring rod are inclined in opposite directions to the stirring blades on the lower side.

[0010] Preferably, a feed pipe is installed on the outer surface of the constant temperature chamber, the bottom of the constant temperature chamber is shaped like a frustum, and a discharge pipe is installed at the lowest point of the frustum shape of the constant temperature chamber.

[0011] Preferably, the elastic telescopic rod includes a fixed rod, which is fixedly connected to the mounting bracket, and a movable rod is slidably connected to the inner surface of the fixed rod. One end of the movable rod is fixedly connected to the scraper, and a return spring is fixedly connected to the end of the movable rod located inside the fixed rod. One end of the return spring is fixedly connected to the inner wall of one side of the fixed rod.

[0012] Preferably, the outer surface of the movable rod is fixedly connected to two limiting blocks, and the inner surface of the fixed rod is provided with a limiting groove that cooperates with the two limiting blocks.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses a driving gear to mesh with two mirror-distributed driven gears, which, together with a gear ring, form a planetary stirring structure. The stirring blades on the driven gear stirring rod and the driving gear stirring rod are staggered. Under the action of multi-axis synchronous rotation and no overlap or interference of the stirring blades, the mud in the tank is driven to form a three-dimensional convection, which effectively avoids mud deposition and wall adhesion, and improves the uniformity of mud mixing.

[0016] 2. By setting up an elastic telescopic rod and a scraper, and with the curvature of the scraper consistent with the inner wall of the constant temperature chamber, this utility model can effectively compensate for minor errors in the processing or installation of the tank body, avoid scratches on the tank wall or damage to the scraper caused by rigid scraping, achieve continuous scraping of the tank wall without dead corners, further reduce the residual rate of mud adhesion, and ensure the uniformity of mud composition during the feeding stage.

[0026] 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.

[0027] like Figures 1 to 5 As shown, this utility model provides a ceramic slurry constant temperature mixing and feeding device, including a constant temperature chamber 1. A power motor 2 is fixedly connected to the top of the constant temperature chamber 1. The output end of the power motor 2 passes through the top of the constant temperature chamber 1 and is fixedly connected to an output shaft 29. A connecting frame 22 is rotatably connected to the outer surface of the output shaft 29. A drive gear 30 is fixedly connected to the bottom end of the output shaft 29 through the connecting frame 22. Two mirror-distributed driven gears 23 are meshed on the outer surface of the drive gear 30. The two driven gears 23 mesh with the drive gear 30 together, and a toothed ring 21 is meshed on the outer surface of the two driven gears 23 together. The toothed ring 21 is fixedly connected to the constant temperature chamber 1.

[0028] Two driven gears 23 and the bottom of the driving gear 30 are fixedly connected to stirring rods 26. Several stirring blades 27 are fixedly connected to the outer surface of the three stirring rods 26. The outer surfaces of the three stirring rods 26 are rotated together and fitted with two mounting brackets 24. Both ends of the two mounting brackets 24 are fixedly connected to elastic telescopic rods 28. The two elastic telescopic rods 28 on the same vertical side are fixedly connected to scrapers 25. The driving gear 30, the two mirror-distributed driven gears 23 and the gear ring 21 cooperate to form a planetary stirring structure. Combined with the synchronous rotation of the three stirring rods 26, compared with the traditional single-shaft stirring equipment, it can drive the mud in the tank to form a multi-directional and multi-angle stirring motion, which greatly improves the uniformity of mud mixing and avoids the mud stratification problem caused by a single stirring direction.

[0029] Specifically, the stirring blades 27 on the stirring rods 26 at the bottom of the two driven gears 23 and the stirring blades 27 on the stirring rods 26 at the bottom of the driving gear 30 are staggered. The horizontal projections of two adjacent stirring blades 27 do not overlap. The staggered distribution design of the stirring blades 27 and the absence of horizontal projection overlap can avoid interference between adjacent stirring blades 27 during the stirring process. At the same time, it can fully cover the stirring area in the constant temperature box 1, reduce the stirring dead corners, further improve the comprehensiveness of mud mixing, and prevent local mud from being insufficiently stirred, which would affect the subsequent molding quality.

[0030] like Figures 1 to 5 As shown, the stirring blades 27 on the stirring rod 26 at the bottom of the driven gear 23 are inclined, and the stirring blades 27 on the upper side of the stirring rod 26 are inclined in opposite directions to the stirring blades 27 on the lower side. The stirring blades 27 on the upper side of the stirring rod 26 corresponding to the driven gear 23 are inclined in opposite directions to the stirring blades 27 on the lower side. During the stirring process, the mud can be driven to form an up-and-down convection motion, breaking the stratified swirling state of the mud. This not only improves the fullness of the integration of the various components of the mud, but also reduces the generation of air bubbles in the mud, ensuring the uniformity of the mud texture.

[0031] Furthermore, a feed pipe 12 is installed on the outer surface of the constant temperature chamber 1, the bottom of the constant temperature chamber 1 is shaped like a frustum, and a discharge pipe 11 is installed at the lowest point of the frustum shape of the constant temperature chamber 1.

[0032] like Figures 1 to 5As shown, the elastic telescopic rod 28 includes a fixed rod 281, which is fixedly connected to the mounting bracket 24. A movable rod 282 is slidably connected to the inner surface of the fixed rod 281. One end of the movable rod 282 is fixedly connected to the scraper 25. A return spring 283 is fixedly connected to the end of the movable rod 282 located inside the fixed rod 281. One end of the return spring 283 is fixedly connected to the inner wall of one side of the fixed rod 281. The elastic force of the return spring 283 can be used to push the scraper 25 to always fit against the inner wall of the constant temperature chamber 1. At the same time, it can adapt to the slight deformation or processing error of the inner wall of the constant temperature chamber 1, avoid damage to the scraper 25 or scratches on the tank wall caused by rigid connection, and improve the stability and service life of the scraper structure.

[0033] It is worth noting that two limiting blocks 284 are fixedly connected to the outer surface of the movable rod 282, and a limiting groove 285 is provided on the inner surface of the fixed rod 281 to cooperate with the two limiting blocks 284. The cooperation between the limiting blocks 284 and the limiting groove 285 can limit the sliding stroke of the movable rod 282 in the fixed rod 281, preventing the movable rod 282 from detaching from the fixed rod 281 due to the force of the return spring 283 or the impact of the mud, ensuring the integrity of the elastic telescopic rod 28 structure and the operational stability, and ensuring that the scraper 25 always maintains an effective wall scraping state.

[0034] like Figures 1 to 5 As shown, the two scrapers 25 are in contact with the inner surface of the constant temperature chamber 1, and the curvature of the two scrapers 25 is consistent with the curvature of the inner wall of the constant temperature chamber 1. The curvature of the scrapers 25 is completely consistent with the inner wall of the constant temperature chamber 1, and the two scrapers 25 are in contact with the tank wall. This can achieve scraping of the inner wall of the constant temperature chamber 1 without dead corners, avoid the mud from adhering and clumping on the tank wall, reduce mud waste, and ensure that the mud composition of the subsequent supply is uniform, preventing the adhering mud from falling off and mixing into the new mud, which would affect the product quality.

[0035] Working principle and process: First, the raw material is added to the constant temperature chamber 1 through the feed pipe 12. The power motor 2 is started, and the power motor 2 drives the output shaft 29 to rotate. The output shaft 29 synchronously drives the drive gear 30 to rotate. The drive gear 30 meshes with two mirror-distributed driven gears 23, and the two driven gears 23 mesh with the gear ring 21 fixed on the constant temperature chamber 1. This allows the two driven gears 23 to both revolve around the drive gear 30 and rotate around their own axes when the drive gear 30 rotates. This, in turn, drives the three stirring rods 26 to rotate synchronously in a planetary motion. The stirring blades 27 on the stirring rods 26 stir and mix the ceramic slurry in the constant temperature chamber 1. Among them, the staggered stirring blades 27 To avoid interference from stirring, the oppositely tilted stirring blades 27 drive the mud to flow up and down, improving the uniformity of mixing. At the same time, when the stirring rod 26 rotates, it drives the mounting frame 24 to move synchronously. The mounting frame 24 drives the scraper 25 to move in a circular motion against the inner wall of the constant temperature chamber 1 through the elastic telescopic rod 28. The return spring 283 of the elastic telescopic rod 28 ensures that the scraper 25 is in close contact with the tank wall. The limiting block 284 and the limiting groove 285 ensure the stable operation of the elastic telescopic rod 28, realizing the removal of mud from the tank wall without dead corners. The mud enters the constant temperature chamber 1 through the feed pipe 12. After being stirred and scraped, it is stably discharged from the discharge pipe 11 at the lowest point of the frustum-shaped structure at the bottom of the constant temperature chamber 1, completing the constant temperature stirring and feeding operation.
