Description

Technical Field

[0001] This utility model relates to the field of wet paperboard production technology, and in particular to a slurry level control device. Background Technology

[0002] Currently, in the wet process of paperboard production, the fiber raw materials are mixed with water to form a suspension, and the fiber distribution in the forming device is relatively dispersed. Due to the water absorption of the fibers, the pre-formed thickness of the fiber blank will inevitably be higher than the actual required thickness. During the drying and forming process of the blank, due to the thermal shrinkage of the fiber material, it is necessary to control the thickness of the fiber blank and the overall moisture content of the blank to effectively control the amount of fiber shrinkage and ensure the thickness of the finished product. There is an urgent need for a liquid level control device for the flow of slurry to meet the control of the fiber blank thickness and the blank moisture content. Utility Model Content

[0003] The purpose of this invention is to provide a slurry level control device to solve the above-mentioned problems.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a slurry level control device, including a wall-mounted frame. The wall-mounted frame is U-shaped with its opening facing downwards. The wall-mounted frame is hung on the wall of a fiber forming device and fixed to the wall of the fiber forming device by a fastening assembly. A limit plate is connected to the wall-mounted frame by a sliding fastening assembly. The lower half of the side wall of the limit plate is an arc-shaped surface. The front end face of the wall-mounted frame is provided with scale lines.

[0006] Furthermore, the fastening assembly includes a fastening bolt, the tail of which penetrates one side wall of the wall-mounted bracket and abuts against the wall of the fiber forming device.

[0007] Furthermore, the inner wall of the sealed end of the wall-mounted bracket is provided with an anti-slip layer.

[0008] Furthermore, the length of the limiting plate is greater than the width of the wall-mounted bracket.

[0009] Furthermore, the sliding fastening assembly includes two symmetrically arranged connecting blocks. The connecting blocks are connected to both ends of the end face of the limiting plate near the wall-mounted bracket. A guide groove is provided on the end face of the wall-mounted bracket opposite to the connecting blocks. A fastening screw is threaded through the connecting blocks, and the tail of the fastening screw abuts against the bottom of the guide groove.

[0010] Furthermore, a level is embedded in the top surface of the limiting plate.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0012] This invention can be used in conjunction with a fiber forming device to control the thickness of the blank, solving the problems of difficult control of the moisture content and fiber shrinkage in the blank during forming. This makes it easier to control the thickness and fiber shrinkage of the insulating wet paper blank, improving product quality, reducing the difficulty of subsequent processing, and increasing production efficiency.

[0019] like Figure 1-4 As shown, a slurry level control device includes a wall-mounted bracket 1, which is U-shaped with its opening facing downwards. The bracket is hung on the wall of a fiber forming device and fixed thereto by a fastening assembly. An anti-slip layer 5 is provided on the inner wall of the sealed end of the bracket 1 to increase slip resistance. The fastening assembly includes a fastening bolt 4, the tail of which penetrates one side wall of the sealed end of the bracket 1 and presses against the fiber forming device wall. In use, the bracket 1 is hung on the fiber forming device wall, and then the fastening bolt 4 is tightened, causing its tail to press against the fiber forming device wall, thereby fixing the bracket 1 in place.

[0020] A limiting plate 2 is connected to the wall-mounted frame 1 via a sliding fastening assembly. The length of the limiting plate 2 is greater than the width of the wall-mounted frame 1. The limiting plate 2 serves to adjust the pressure limit position, thereby controlling the overall thickness of the slurry and the amount of fiber shrinkage.

[0021] The lower half of the side wall of the limiting plate 2 is an arc-shaped surface. The arc-shaped surface can effectively guide the slurry to the lowest plane of the limiting plate 2 for pressing the liquid surface, and can also effectively prevent the slurry from jumping onto the top surface of the limiting plate 2. The front end face of the wall-mounted bracket 1 is provided with a scale line 3. The height of the limiting plate 2 can be determined by observing where the limiting plate 2 is located on the scale line 3.

[0022] The sliding fastening assembly includes two symmetrically arranged connecting blocks 6. The connecting blocks 6 are connected to both ends of the end face of the limiting plate 2 near the wall mount 1. The connecting blocks 6 are connected to the upper half of the limiting plate 2. The wall mount 1 has a guide groove 7 on the end face opposite to the connecting blocks 6. A fastening screw 8 is threaded through the connecting blocks 6, and the tail of the fastening screw 8 abuts against the bottom of the guide groove 7.

[0023] A level is embedded in the top surface of the limiting plate 2, which can be used to determine whether the limiting plate 2 is in a horizontal state.

[0024] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
