[0002] Ceramic membranes are a type of inorganic membranes and belong to solid membrane materials in membrane separation technology. They mainly use inorganic ceramic materials such as alumina, zirconia, titanium oxide, and silicon oxide in different specifications as supports, and are formed by surface coating and high-temperature firing.

[0003] After retrieval, a utility model with the Chinese patent publication number CN211837292U discloses a low-temperature film forming device for manufacturing ceramic membranes, including a box body. A feeding port is opened on the right side of the top of the box body. A rotating rod is provided on the left side of the feeding port and at the top of the box body. A baffle is provided on the right side of the rotating rod. A first sliding plate is provided below the baffle and on the left inner wall of the box body. A conical shaft rod is provided below the first sliding plate.

[0004] The above device forms a film by controlling the pressure plate to extrude the raw materials on the top of the conveyor belt. However, these raw materials directly slide onto the top of the conveyor belt, so it is difficult to ensure that the raw materials are evenly distributed, and thus the quality of the extruded ceramic membrane will also be affected.

Start the motor outside the support plate. The motor drives the reciprocating screw rod to rotate between the two support plates. Under the drive of the reciprocating screw rod and the cooperation of the first limiting rod, the installation block will reciprocate left and right on the top of the installation frame, and the leveling plate can also move synchronously with the installation block. The piled-up part of the raw materials will be blocked and then fall into the sunken part of the raw material layer when the leveling plate moves, so as to ensure that the raw material layer is evenly distributed enough, and the position of the leveling plate can also be adjusted as needed. By driving the first screw rod to rotate through the knob, the leveling plate can be changed arbitrarily along the vertical direction under the drive of the first screw rod and the cooperation of the second limiting rod.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0024] The present utility model provides a technical solution: As Figure 2 and Figure 3 shown, in this embodiment, a film forming device for alumina ceramic coating includes a mounting frame 1, and is characterized in that: a smoothing assembly 5 is installed outside the mounting frame 1. The smoothing assembly 5 includes two support plates 501 fixedly connected to the outer walls of both ends of the mounting frame 1. The same reciprocating lead screw 502 is rotatably connected between the two support plates 501. An installation block 505 is sleeved outside the reciprocating lead screw 502. A slider forming a transmission fit with the reciprocating lead screw 502 is arranged inside the installation block 505. A plurality of first limiting rods 503 are fixedly connected between the two support plates 501. The installation block 505 is slidably sleeved outside the plurality of first limiting rods 503. A motor 504 is fixedly installed on the outer wall of one end of one of the support plates 501. The rotating shaft of the motor 504 and one end of the reciprocating lead screw 502 are coaxially fixed.

[0025] A first screw 506 is threadedly connected to the middle of the installation block 505. One end of the bottom of the first screw 506 is rotatably connected to a smoothing plate 508. A plurality of second limiting rods 507 are slidably inserted into one side of the installation block 505. One ends of the plurality of second limiting rods 507 are fixedly connected to the top outer wall of the smoothing plate 508.

[0026] Start the motor 504 outside the support plate 501. The motor 504 drives the reciprocating lead screw 502 to rotate between the two support plates 501. The installation block 505 will reciprocate left and right on the top of the mounting frame 1 under the driving of the reciprocating lead screw 502 and in cooperation with the first limiting rods 503. The smoothing plate 508 can also move synchronously with the installation block 505. The piled-up part of the raw materials will be blocked, and then fall into the sunken part of the raw material layer when the smoothing plate 508 moves, so as to ensure that the raw material layer is sufficiently uniform, and the position of the smoothing plate 508 can also be adjusted as needed. By rotating the knob to drive the first screw 506 to rotate, the smoothing plate 508 can be changed arbitrarily along the vertical direction under the driving of the first screw 506 and in cooperation with the second limiting rods 507.

[0027] As Figure 2 and Figure 4 shown, a correction assembly 6 is installed on one side of the mounting frame 1. The correction assembly 6 includes two limiting sleeves 601 fixedly connected to one side of the bottom outer wall of the mounting frame 1. A moving rod 602 is slidably inserted into each of the two limiting sleeves 601. One ends of the tops of the two moving rods 602 are fixedly connected with a correction plate 604. The tops of the two correction plates 604 are in an inclined state and are symmetrically arranged. A second screw 603 is threadedly connected to the middle of each of the two moving rods 602. One ends of the two second screws 603 are respectively rotatably connected to the outer walls of both ends of the mounting frame 1.

[0028] Inside the mounting frame 1, a conveyor belt is installed (both inner walls at the two ends of the mounting frame 1 are fixedly connected to the same support plate, and the support plate is in contact with the upper half of the conveyor belt, so as to achieve a supporting effect and is conducive to improving the forming effect). The bottom walls of the two correction plates 604 are both in contact with the top wall of the conveyor belt.

[0029] The raw materials fall onto the top of the conveyor belt and will slide down along the inclined part of the correction plate 604 to the bottom. And under the restriction of the correction plate 604, these raw materials can reach the required width, and the position of the correction plate 604 can also be adjusted as needed. By rotating the knob to drive the second screw 603 to rotate outside the mounting frame 1, the moving rod 602 will move away from or close to the mounting frame 1 at will under the drive of the second screw 603 and the cooperation of the limit sleeve 601. Furthermore, the position of the correction plate 604 will move synchronously with the moving rod 602.

[0030] As Figure 4 shown, scale lines 605 are provided on the inner walls at the bottoms of the two moving rods 602, and the scale lines 605 are perpendicular to the mounting frame 1. By referring to the scale lines 605, the adjustment can be ensured to be more accurate.

[0031] As Figure 2 shown, the leveling plate 508 is integrally bent, and the concave part faces the correction assembly 6. When the leveling plate 508 is translated, half of it will gradually move to the top of the conveyor belt to achieve the effect of pushing the raw materials, and the other half will gradually retract without affecting the leveling work.

[0032] As Figure 1 and Figure 2 shown, on the other side of the outer wall at the top of the mounting frame 1, a support frame 2 is fixedly connected. A hydraulic cylinder 3 is fixedly installed on the outer wall at the top of the support frame 2. The output end of the hydraulic cylinder 3 is fixedly connected to a pressure plate 4. By starting the hydraulic cylinder 3, the pressure plate 4 can be driven to squeeze on the top of the raw materials, so that the raw material layer can be formed.

[0033] The present utility model provides a film forming device for alumina ceramic coating, and the specific working principle is as follows:

[0034] When the device is working, the raw materials fall onto the top of the conveyor belt and will slide down along the inclined part of the correction plate 604 to the bottom. Under the restriction of the correction plate 604, these raw materials can reach the required width, and the position of the correction plate 604 can also be adjusted as needed. By rotating the knob to drive the second screw 603 to rotate outside the mounting frame 1, the moving rod 602 will move away from or close to the mounting frame 1 at will under the drive of the second screw 603 and the cooperation of the limit sleeve 601. Furthermore, the position of the correction plate 604 will move synchronously with the moving rod 602. Then, start the motor 504 outside the support plate 501. The motor 504 drives the reciprocating screw rod 502 to rotate between the two support plates 501. The mounting block 505 will reciprocate left and right on the top of the mounting frame 1 under the drive of the reciprocating screw rod 502 and the cooperation of the first limit rod 503. The leveling plate 508 can also move synchronously with the mounting block 505. Some of the piled-up raw materials will be blocked, and then fall into the sunken part of the raw material layer when the leveling plate 508 moves, so as to ensure that the raw material layer is sufficiently uniform. Moreover, the position of the leveling plate 508 can also be adjusted as needed. By rotating the knob to drive the first screw 506 to rotate, the leveling plate 508 can be changed vertically at will under the drive of the first screw 506 and the cooperation of the second limit rod 507.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
