Description

Technical Field

[0001] The utility model relates to the technical field of papermaking equipment, in particular to a pulping and filtering device for paper production. Background Art

[0002] Pulping, also known as beating, is an operation process that uses mechanical action to treat pulp fibers suspended in water, performs mechanical or fluid treatment on pulp fibers, changes the morphology of fibers, makes them have the characteristics required for production on paper machines, and makes the produced paper reach the expected quality. In order to ensure the quality of the pulp after beating, a filter screen is generally provided in the pulping device to facilitate filtering the pulp after beating, so that some materials that are not completely broken up can be separated, thereby maintaining the quality of the pulp. It is difficult to clean the unbroken materials remaining inside the device and on the filter screen. Therefore, the patent publication number CN216156246U discloses "a pulping device for papermaking". In the filtering part, the inverted V-shaped filter screen in the filter box and the two limit bearing strips can be set up to discharge the pulped materials from the beating barrel for filtration. At the same time, the filter screen is easy to disassemble and clean, thereby improving the convenience of use and the efficiency of the pulping operation.

[0003] The above-mentioned filtering part makes it easy to disassemble the filter so that the filter can be cleaned easily. However, when there are multiple beaters and the size of the beaters is large, the flow rate of the pulping material is large, and the filter will be quickly blocked by the undisturbed material, so it needs to be cleaned continuously. The above-mentioned method of cleaning the filter is not suitable for continuous cleaning, which affects the filtration efficiency. Utility Model Content

[0018] like Figure 1 As shown, the utility model provides a pulping and filtering device for paper production, including a receiving box 1 and a pulping pipe 9, a bracket 2 is fixedly installed on the top of the receiving box 1, at least two driving rollers 3 driven by a motor are fixedly installed on the bracket 2, a filtering mesh belt 4 is sleeved on the driving roller 3, a blowing assembly 5 is arranged on the upper right side of the filtering mesh belt 4, a slag trough box 6 is arranged on the right side of the receiving box 1, the slag trough box 6 is arranged below the blowing assembly 5, and the filtering mesh belt 4 is arranged below the pulping pipe 9.

[0019] The pulping pipe 9 is used to discharge the pulping liquid produced by the pulping machine. The pulping liquid is discharged from the pulping pipe 9 and falls onto the filter mesh belt 4. The holes arranged on the filter mesh belt 4 can allow the pulp to be filtered down and the coarse fibers to be filtered on the filter mesh belt 4. The filter mesh belt 4 is tensioned by using the driving roller 3 and transmits the coarse fibers filtered out of the pulp like a conveyor belt. When it is transmitted to the right side, under the influence of its own gravity and the auxiliary blowing of the blowing component 5, the coarse fibers fall into the slag trough box 6 and can be collected for recycling. The filter mesh belt 4 circulates and transmits, thereby enabling continuous filtering.

[0020] The blowing assembly 5 includes a support frame 501, which is fixedly mounted on the top of the bracket 2, and an air pump 502 is fixedly mounted on the support frame 501, and a high-pressure blowing nozzle 503 is connected to the output end of the air pump 502. The support frame 501 provides support, and the air pump 502 can drive the high-pressure blowing nozzle 503 to blow the surface of the filter mesh belt 4. The high-pressure blowing nozzle 503 blows obliquely on the cross-section of the bend of the filter mesh belt 4, which can better blow off the coarse fibers.

[0021] A water spray gun 7 is installed on the support frame 501. In order to prevent the mesh of the filter mesh belt 4 from being clogged by the slurry after long-term use, the controller is used to control the water spray gun 7 to spray water. After the filter mesh belt 4 has been used for a period of time, the water spray gun 7 can be turned on to rinse the filter mesh belt 4 with clean water to prevent the mesh holes from being clogged and causing blockage.

[0022] A vibration assembly 8 is mounted on the bracket 2. The vibration assembly 8 can vibrate the filter mesh cloth, which is conducive to filtering and falling of the slurry.

[0023] The vibration assembly 8 includes a spring group 801 and a vibration motor 802. The top of the spring group 801 is connected to the driving roller 3. The bottom of the spring group 801 is fixedly mounted on the bracket 2. The bottom of the vibration motor 802 is fixedly mounted with a main beam 803. Both ends of the main beam 803 are fixedly connected to the top of the spring group 801. The spring group 801 is used to enable the driving roller 3 and the filter grid belt 4 to swing to a certain extent. The vibration motor 802 is used to vibrate. The main beam 803 is used for conduction, so that the filter grid belt 4 can be vibrated, which is conducive to the falling of the slurry.

[0024] Working principle: when in use, the slurry is discharged from the pulping pipe 9 and falls onto the filter mesh belt 4. The holes set on the filter mesh belt 4 can allow the slurry to filter down and filter the coarse fibers on the filter mesh belt 4. The driving roller 3 drives the filter mesh belt 4 to transport. The slurry water falls into the receiving box 1 from the filter holes of the filter mesh belt 4. The coarse fibers are transported to the right side and, under the influence of their own gravity and the auxiliary blowing of the blowing component 5, the coarse fibers fall into the slag trough box 6 and can be concentrated for recycling. The filter mesh belt 4 circulates and transports, and can filter continuously. The vibration component 8 can be used to vibrate the filter mesh cloth, which is conducive to the slurry water being filtered and falling. In order to prevent the mesh of the filter mesh belt 4 from being blocked by the slurry little by little after long-term use, the controller is used to control the water spray gun 7 to spray water. After the filter mesh belt 4 has been used for a period of time, the water spray gun 7 can be turned on to rinse the filter mesh belt 4 with clean water to prevent the mesh holes from being blocked and causing blockage.
