Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly paper production technology, and in particular to an environmentally friendly paper production equipment that provides uniform mixing. Background Technology

[0002] In recent years, with increasingly stringent environmental protection requirements, the paper industry has continuously increased its demand for energy conservation, emission reduction, and resource recycling. Existing equipment filtration systems typically employ fixed screens or single-stage filtration, which are prone to clogging and cannot effectively separate impurities of different particle sizes, resulting in high impurity content in white water and affecting recycling efficiency. White water recovery systems mostly rely on external pumps and pipelines, lacking self-cleaning functions; after long-term operation, the filter screens are easily clogged by fibers, reducing filtration efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as low filtration efficiency and insufficient white water recovery, and to provide an environmentally friendly paper production equipment with uniform mixing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an environmentally friendly paper production equipment for uniform mixing, comprising a pulper, a headbox fixedly connected to one end of the pulper, a preliminary filter box provided on the inner wall of the headbox, a storage box provided on the inner wall of the headbox, a recycling trough provided on the inner wall of the headbox, a screen fitted onto the inner wall of the preliminary filter box, a slot fixedly connected to the inner wall of the headbox, a filter plate fitted onto the inner wall of the slot, a water pump fixedly connected to one side of the headbox, a guide pipe fixedly connected to the outer surface of the water pump, and an adjustment frame fixedly connected to one side of the headbox.

[0005] In a preferred embodiment, a motor is fixedly connected to one side of the adjusting frame, a lead screw is fixedly connected to one end of the motor, a bearing is fixedly connected to one end of the lead screw, a movable plate is sleeved on the lead screw, a limit rod is fixedly connected to one side of the movable plate, and a scraper is fixedly connected to one end of the limit rod.

[0006] In a preferred embodiment, the inner wall of the movable plate is threadedly connected to the outer surface of the lead screw, and the inner wall of the adjusting frame is slidably connected to the outer surface of the limiting rod.

[0007] In a preferred embodiment, the outer surface of the filter plate is engaged with the inner wall of the slot.

[0008] In a preferred embodiment, the outer surface of the screen is engaged with the inner wall of the primary filtration box.

[0009] In a preferred embodiment, a conveying pipe is fixedly connected to one side of the pulper, and a through hole is opened on one side of the headbox, which is fixedly connected to the conveying pipe.

[0010] In a preferred embodiment, the bearing is placed inside the adjusting frame, and the outer surface of the bearing is fixedly connected to the inner wall of the adjusting frame.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This invention uses a pulper to break down waste paper or raw materials into pulp, which is then injected into a preliminary filter box inside the headbox. Large particles of impurities in the pulp are sieved through a screen, leaving them on the screen surface. The pulp then falls through the screen into a storage box, where it is filtered by a filter plate. The filtered pulp then passes through the storage box to the next stage of paper production. The large amount of white water contained in the pulp passes through the filter plate into a recycling tank, where a water pump injects the white water into a guide pipe, which then re-injects it into the pulper. This achieves water recycling and improves water utilization efficiency. The filter plate is easily replaced by a locking mechanism. Attached Figure Description

[0019] 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.

[0020] Example 1

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: an environmentally friendly paper production equipment for uniform mixing, including a pulper 1, a headbox 2 fixedly connected to one end of the pulper 1, a preliminary filter box 5 opened on the inner wall of the headbox 2, a storage box 7 opened on the inner wall of the headbox 2, a recycling tank 8 opened on the inner wall of the headbox 2, a screen 6 sleeved on the inner wall of the preliminary filter box 5, a slot 9 fixedly connected to the inner wall of the headbox 2, a filter plate 10 sleeved on the inner wall of the slot 9, a water pump 3 fixedly connected to one side of the headbox 2, a guide pipe 4 fixedly connected to the outer surface of the water pump 3, and an adjusting frame 11 fixedly connected to one side of the headbox 2.

[0022] In this embodiment, waste paper or raw materials are broken down into pulp by a pulper 1, and then injected into the preliminary filter box 5 inside the headbox 2. Large particles of impurities mixed in the pulp are then screened by a screen 6, leaving the large particles on the surface of the screen 6. The pulp then falls into the storage box 7 through the screen 6. The pulp is then filtered by a filter plate 10. The filtered pulp then passes through the storage box 7 to the next paper production stage. The large amount of white water contained in the pulp is filtered through the filter plate 10 into the recycling tank 8, and then pumped by a water pump 3 into the guide pipe 4. The white water is then reinjected into the pulper 1 through the guide pipe 4, thereby realizing the recycling of water resources and improving the efficiency of water use. The filter plate 10 is connected by a slot 9, which facilitates the replacement of the filter plate 10 by the staff.

[0023] Example 2

[0024] like Figures 1-4 As shown, a motor 12 is fixedly connected to one side of the adjusting frame 11, a lead screw 13 is fixedly connected to one end of the motor 12, a bearing 15 is fixedly connected to one end of the lead screw 13, a moving plate 14 is sleeved on the lead screw 13, a limit rod 16 is fixedly connected to one side of the moving plate 14, a scraper 17 is fixedly connected to one end of the limit rod 16, the inner wall of the moving plate 14 is threadedly connected to the outer surface of the lead screw 13, and the inner wall of the adjusting frame 11 is slidably connected to the outer surface of the limit rod 16.

[0025] In this embodiment, after the filter plate 10 filters out the white water, some pulp may adhere to the surface of the filter plate 10, which may affect the discharge of the white water. The motor 12 drives the lead screw 13 to rotate inside the adjusting frame 11. The bearing 15 ensures that the lead screw 13 rotates more smoothly. Since the lead screw 13 is threadedly connected to the moving plate 14 and the limiting rod 16 is slidably connected to the adjusting frame 11, the moving plate 14 is moved while the lead screw 13 rotates. The moving plate 14 drives the limiting rod 16 to move, thereby driving the scraper 17 to clean the surface of the filter plate 10, ensuring that no pulp adheres to the surface of the filter plate 10.

[0026] Working principle:

[0027] like Figures 1-4 As shown, in this invention, the worker uses a pulper 1 to break down waste paper and raw materials into pulp, which is then injected into the preliminary filter box 5 inside the headbox 2. Large particles of impurities mixed in the pulp are then screened through a screen 6, leaving them on the surface of the screen 6. The pulp then falls through the screen 6 into the storage box 7, where it is filtered by a filter plate 10. The filtered pulp then passes through the storage box 7 for the next paper production stage. The large amount of white water originally contained in the pulp passes through the filter plate 10 into the recycling tank 8, where it is pumped by a water pump 3 into a guide pipe 4, and then reinjected into the pulper 1 through the guide pipe 4. The internal structure of the filter plate 10 enables the recycling of water resources and improves water utilization efficiency. After the filter plate 10 filters out white water, some pulp may adhere to the surface of the filter plate 10, which may affect the discharge of white water. The motor 12 drives the lead screw 13 to rotate inside the adjusting frame 11. The bearing 15 ensures that the lead screw 13 rotates more smoothly. Since the lead screw 13 is threadedly connected to the moving plate 14 and the limiting rod 16 is slidably connected to the adjusting frame 11, the moving plate 14 is moved while the lead screw 13 rotates. The moving plate 14 drives the limiting rod 16 to move, thereby driving the scraper 17 to clean the surface of the filter plate 10, ensuring that no pulp adheres to the surface of the filter plate 10.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
