Description

Technical Field

[0001] This utility model relates to the field of ceramic manufacturing technology, and more specifically, to a double-helix vacuum extrusion dewatering device for ceramic clay. Background Technology

[0002] Ceramic clay is a mixture of plastic raw materials, lean raw materials, and fluxing raw materials. Dehydration of ceramic clay improves its molding and drying properties, reduces shrinkage and deformation during drying, and increases yield. Dehydrated clay is easier to process and shape, and also reduces deformation and cracking during firing. However, existing vacuum extrusion dehydration devices for ceramic clay still have the following drawbacks:

[0003] (1) The existing equipment dewatering process can remove most of the water, but there will be residual ceramic clay in the dewatered clay suspension, which will result in waste of resources. Furthermore, the dewatered clay will not be further mixed and dried, which may lead to uneven moisture distribution and cause deformation, cracking or uneven shrinkage of the clay in subsequent processes.

[0004] (2) In traditional clay dewatering devices, the clay may become too viscous or accumulate locally without stirring, increasing the internal resistance of the equipment and causing blockage and jamming. To address this, a double-helix vacuum extrusion dewatering device for ceramic clay is proposed. Utility Model Content

[0005] The purpose of this utility model is to address the problem that the existing double-spiral vacuum extrusion dewatering device for ceramic clay can remove most of the water during the dewatering process, but there will be residual ceramic clay in the clay suspension after dewatering, which will result in waste of resources. Furthermore, the clay after dewatering is not further mixed and dried, which may lead to uneven moisture distribution and cause deformation, cracking or uneven shrinkage of the clay in subsequent processes.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] The present invention is as follows: a double-helix vacuum extrusion dewatering device for ceramic clay, including a clay box, the top of which is provided with a dewatering mechanism for vacuum dewatering the clay suspension, and a swinging component for placing the clay accumulation is provided on one side of the dewatering mechanism.

[0008] The dewatering mechanism includes a first motor bolted to the side wall of the mud box. A roller is fixedly connected to the output end of the first motor. Several filter holes are opened on the side wall of the roller. A filter cloth is provided on the side wall of the roller. A rectangular plate is fixedly connected to the side wall of the mud box. A vacuum pump is provided at the top of the rectangular plate. A flexible hose is connected to the output end of the vacuum pump. An outlet pipe is connected to the bottom of the mud box. A first solenoid valve is provided on the outer wall of the outlet pipe. A support plate is fixedly connected to the side wall of the mud box away from the vacuum pump. A water pump is provided at the top of the support plate. A liquid extraction pipe is connected to the input end of the water pump. A liquid outlet pipe is connected to the output end of the water pump. A mixing and drying assembly is provided on one side of the mud box.

[0009] As a preferred technical solution of this utility model, the mixing and drying assembly includes a mixing channel disposed on one side of the mud box, a feeding hopper connected to the top of the mixing channel, a second motor bolted to one side of the mixing channel, a first gear disposed at the output end of the second motor, a second gear disposed on one side of the first gear and meshing with the first gear, a rotating rod coaxially disposed on the side wall of the first gear and the second gear, a spiral blade welded to the side wall of the rotating rod, the spiral blades being staggered, two dryers disposed on the inner top wall of the mixing channel, and a discharge channel connected to the bottom of the mixing channel away from the second motor.

[0010] As a preferred technical solution of this utility model, the swing assembly includes a third motor bolted to the side wall of the mud box, a rotating component fixedly connected to the output end of the third motor, a connecting rod hinged to one side of the rotating component, a swing component hinged to one end of the connecting rod and rotatably connected to the inner wall of the mud box, and a crossbar fixedly connected to the bottom of the swing component.

[0011] As a preferred technical solution of this utility model, two strip plates are fixedly connected to the side wall of the mud box, and adjusting components are threadedly connected to the opposite side walls of the two strip plates. A scraper is fixedly connected to the top of the adjusting component, and the scraper is inclined.

[0012] As a preferred technical solution of this utility model, a recovery box is provided at the bottom of the liquid outlet pipe and the outlet pipe, a filter screen is provided on the inner wall of the recovery box, a recovery pipe is connected to the outer wall of the bottom of the recovery box, and a second solenoid valve is provided on the outer wall of the recovery pipe.

[0013] As a preferred technical solution of this utility model, a scraper is fixedly connected to the bottom of the crossbar, and the bottom of the scraper is provided with an inclined surface.

[0014] As a preferred technical solution of this utility model, the filter cloth is made of polyester fiber.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. Through the dewatering mechanism, the first motor drives the roller to rotate and starts the vacuum pump to extract the air from the roller, creating a negative pressure state inside the roller. This separates the solid impurities in the clay suspension into a filter cake, which adheres to the filter cloth, thus achieving solid-liquid separation and ensuring the dewatering effect of the ceramic clay. When the clay enters the mixing channel, the second motor drives the first gear to rotate, which in turn drives the spiral blades to rotate, allowing the clay to be fully turned and mixed evenly in the mixing channel. At the same time, the dryer generates heat to heat and dry the ceramic clay in the mixing channel, reducing the moisture content of the clay and enabling it to reach the degree of dryness required for subsequent processing, thereby improving the quality of the clay.

[0017] 2. With the swing component in place, when the third motor drives the rotating part to rotate, the rotation of the rotating part pulls the swing component to swing back and forth through the connecting rod. The crossbar at the bottom of the swing component swings accordingly, thereby stirring and turning the ceramic clay in the clay box, preventing the clay from accumulating in the clay box and causing uneven dehydration. The swing of the crossbar can break the accumulation of clay, keeping the clay in a loose state, which is conducive to the drainage of water. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0025] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] like Figure 1 As shown, this embodiment proposes a ceramic clay double-helix vacuum extrusion dewatering device, including a clay box 1. The top of the clay box 1 is provided with a dewatering mechanism 2 for vacuum dewatering the clay suspension, and a swinging component 3 for placing the clay accumulation is provided on one side of the dewatering mechanism 2.

[0029] like Figure 3 and Figure 4As shown, the dewatering mechanism 2 includes a first motor 201 bolted to the side wall of the mud box 1. A roller 202 is fixedly connected to the output end of the first motor 201. The first motor 201 drives the roller 202 to rotate, thereby driving the mud through the dewatering process. Several filter holes 203 are provided on the side wall of the roller 202, and a filter cloth 204 is provided on the side wall of the roller 202. The filter holes 203 and the filter cloth 204 prevent mud from entering the interior of the roller 202. A rectangular plate 205 is fixedly connected to the side wall of the mud box 1. A vacuum pump 206 is provided on the top of the rectangular plate 205. The vacuum pump 206 is used to support and fix the vacuum pump 206. A flexible hose 207 is connected to the output end of the vacuum pump 206, enabling the vacuum pump 206 to effectively extract gas from the roller 202 and maintain a negative pressure state within the mud tank 1. An outlet pipe 208 is connected to the bottom of the mud tank 1, used to drain liquid from the mud tank 1 for subsequent processing. A first solenoid valve 209 is installed on the outer wall of the outlet pipe 208. By controlling its opening and closing, the liquid drainage time and flow rate can be precisely controlled. The mud tank 1 is located away from the vacuum pump. A support plate 210 is fixedly connected to the side wall of roller 206. A water pump 211 is installed on the top of the support plate 210. The input end of the water pump 211 is connected to a liquid extraction pipe 212, and the output end of the water pump 211 is connected to a liquid outlet pipe 213. The water pump 211 can extract the water separated in the roller body 202 to prevent water from accumulating in the roller body 202 and affecting the dehydration effect. A mixing and drying component 214 is installed on one side of the mud box 1. When in use, the ceramic mud suspension to be dehydrated is put into the mud box 1. After confirming that the mud suspension covers the bottom of the roller body 202, the first motor 201 is started. The vacuum pump 206 is activated, which drives the roller 202 to rotate. The vacuum pump 206 is then activated to extract the air from the roller 202, creating a negative pressure state inside the roller 202. This separates the solid impurities in the mud suspension into a filter cake, which adheres to the filter cloth 204, thus achieving solid-liquid separation. Then, the water pump 211 is activated to extract the separated liquid from the roller 202 for subsequent processing. Vacuum adsorption can effectively remove water from the mud suspension, achieving full utilization of the mud and ensuring the dehydration effect of the ceramic mud, providing suitable materials for subsequent ceramic forming processes.

[0030] like Figure 3As shown, the mixing and drying assembly 214 includes a mixing channel 2141 disposed on one side of the clay box 1. The mixing channel 2141 provides a space for mixing and drying the clay. A feed hopper 2142 is connected to the top of the mixing channel 2141. The feed hopper 2142 is used to introduce the dehydrated ceramic clay into the mixing channel 2141. A second motor 2143 is bolted to one side of the mixing channel 2141. The second motor 2143 provides a power source. A first gear 2144 is disposed at the output end of the second motor 2143, and a second gear 214 is disposed on one side of the first gear 2144. 5. It meshes with the first gear 2144. A rotating rod 2146 is coaxially arranged on the side wall of the first gear 2144 and the second gear 2145. The first gear 2144 and the second gear 2145 cooperate with each other to transmit the rotational power of the second motor 2143 to the rotating rod 2146. Spiral blades 2147 are welded to the side wall of the rotating rod 2146. The spiral blades 2147 are staggered. The staggered arrangement of the spiral blades 2147 increases the mixing effect of the mud, which can make the mud fully turn over and mix evenly in the mixing channel 2141, thereby improving the quality and consistency of the mud. Two dryers 2148 are installed on the inner top wall of the mixing channel 2141. The dryers 2148 are used to dry the ceramic clay in the mixing channel 2141. A discharge channel 2149 is connected to the bottom of the mixing channel 2141 away from the second motor 2143. The discharge hopper is used to draw the ceramic clay after mixing and drying from the mixing channel 2141 for subsequent processing. In use, the dehydrated ceramic clay enters the mixing channel 2141 through the feed hopper 2142 connected to the top of the mixing channel 2141. The second motor 2143 is started, and its output end drives the second motor 2148. When gear 2144 rotates, it drives gear 2145 to rotate synchronously, thereby transmitting the power of motor 2143 to two rotating rods 2146, which in turn drive spiral blades 2147 to rotate. During the rotation, spiral blades 2147 stir the clay in mixing channel 2141, ensuring the consistency of clay composition. At the same time, dryer 2148 generates heat to heat and dry the ceramic clay in mixing channel 2141, reducing the moisture content of the clay and bringing it to the required dryness level for subsequent processing, thus improving the quality of the clay.

[0031] like Figure 5As shown, the oscillating assembly 3 includes a third motor 301 bolted to the side wall of the mud box 1. A rotating component 302 is fixedly connected to the output end of the third motor 301. The third motor 301 drives the rotating component 302 to rotate by outputting power, providing initial power. The rotating component 302 plays a role in power transmission and conversion, transforming the rotational motion of the motor into the oscillating motion of the oscillating component 304. A connecting rod 303 is hinged to one side of the rotating component 302, and the oscillating component 304 is hinged to one end of the connecting rod 303 and rotatably connected to the inner wall of the mud box 1. A crossbar 305 is fixedly connected to the bottom of the oscillating component 304, and the oscillating component 304 transmits power to the crossbar 305. The lever 305 causes the crossbar 305 to swing. During use, the third motor 301 drives the rotating part 302 to rotate. The rotation of the rotating part 302 pulls the swinging part 304 to swing back and forth through the connecting rod 303. The crossbar 305 at the bottom of the swinging part 304 swings accordingly, thereby stirring and turning the ceramic clay in the clay box 1. This can make the clay more evenly distributed in the clay box 1 and improve the dewatering efficiency. During the dewatering process, the clay may accumulate in the clay box 1 due to gravity and other factors, resulting in uneven dewatering. The swinging of the crossbar 305 can break the accumulation of the clay and keep the clay in a loose state, which is conducive to the discharge of water.

[0032] like Figure 1 As shown, two strip plates 4 are fixedly connected to the side wall of the mud box 1. Adjusting parts 5 are threadedly connected to the opposite side walls of the two strip plates 4. A scraper 6 is fixedly connected to the top of the adjusting part 5. The scraper 6 is inclined and can easily scrape off the mud adsorbed by vacuum on the roller body 202. Rotating the adjusting part 5 can adjust the angle of the scraper 6, so as to better fit the outer wall of the roller body 202 and adapt to different roller body 202 specifications.

[0033] like Figure 1 As shown, a recovery tank 7 is installed at the bottom of the liquid outlet pipe 213 and the outlet pipe 208. A filter screen 8 is installed on the inner wall of the recovery tank 7, and a recovery pipe 9 is connected to the outer wall of the bottom of the recovery tank 7. A second solenoid valve 10 is installed on the outer wall of the recovery pipe 9. The filter screen 8 can filter the separated liquid, intercepting mud particles and impurities on the filter screen 8, so that the relatively pure liquid enters the bottom of the recovery tank 7 through the filter screen 8. The filtered pure liquid is more conducive to subsequent recycling and improves resource utilization. The second solenoid valve 10 can adjust the opening of the recovery pipe 9 according to actual needs to meet the liquid flow requirements of different production stages.

[0034] like Figure 2 As shown, a scraper 11 is fixedly connected to the bottom of the crossbar 305. The bottom of the scraper 11 is provided with an inclined surface. The mud will come into contact with the inner wall of the mud box 1. Some mud may adhere to the inner wall of the box. The scraper 11 can scrape off the residual mud on the inner wall of the box.

[0035] like Figure 1 As shown, the filter cloth 204 is made of polyester fiber. The polyester fiber filter cloth 204 has uniform fiber fineness, which can form a relatively dense filter pore structure, enabling precise filtration and reducing the mixing of impurities.

[0036] Specifically, in use, the ceramic clay double-screw vacuum extrusion dewatering device works as follows: The ceramic clay suspension to be dewatered is placed into the clay box 1, ensuring the suspension covers the bottom of the roller 202. Then, the third motor 301 starts, its output driving the rotating component 302 to rotate. The rotation of the rotating component 302, via the connecting rod 303, pulls the oscillating component 304 to reciprocate. The crossbar 305 at the bottom of the oscillating component 304 swings accordingly, thereby stirring and agitating the ceramic clay in the clay box 1, allowing for a more uniform distribution of the clay within the box (e.g., ...). Figure 5 (As shown), then the first motor 201 is started, and its output end drives the roller 202 to rotate. The vacuum pump 206 is started to extract the air from the roller 202, creating a negative pressure state inside the roller 202. This separates the solid impurities in the mud suspension to form a filter cake, which adheres to the filter cloth 204, thereby achieving solid-liquid separation. Next, the water pump 211 is started to extract the separated liquid from the roller 202 to the recovery tank 7 for subsequent processing. The dehydrated ceramic mud enters the mixing channel 2141 through the feed hopper 2142 connected to the top of the mixing channel 2141. The second motor 2143 starts, and its output drives the first gear 2144 to rotate. The rotation of the first gear 2144 drives the second gear 2145 to rotate synchronously, thus transmitting the power of the second motor 2143 to the two rotating rods 2146, which in turn drive the spiral blades 2147 to rotate. During the rotation, the spiral blades 2147 stir the clay in the mixing channel 2141. The dryer 2148 generates heat to heat and dry the ceramic clay in the mixing channel 2141, reducing the moisture content of the clay. Finally, the clay is discharged through the discharge hopper for subsequent processing (such as...). Figure 3 and Figure 4 (As shown).

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
