Description

Technical Field

[0001] This utility model relates to the technical field of pulp mixing equipment, specifically to a pulp mixing device. Background Technology

[0002] Currently, after the mixing equipment has been used for a period of time, pulp fibers adhere to the mixing shaft and the barrel wall, affecting subsequent processing and production. When producing different types of pulp raw materials, there is also pollution. To address this, manual scraping of the barrel wall is usually performed periodically, which is inefficient, requires workers to enter the barrel, creates a poor working environment, and has poor cleaning results.

[0003] The existing technology patent announcement number CN219744535U describes a pulp mixing device that can complete the scraping operation on the barrel wall without the need for personnel to enter, and uses high-pressure water flow to clean the mixing shaft, achieving a comprehensive cleaning operation and improving cleaning efficiency.

[0004] However, the aforementioned patented mixing tank has an open top structure. When the pulp is being mixed or the inner wall is being cleaned, a certain amount of pulp is very likely to splash out from the open top and land on the meshing teeth. This can cause the drive motor to run and the gears to mesh with the meshing teeth, which can lead to jamming and affect the rotation effect of the meshing teeth on the scraper. Utility Model Content

[0005] To solve the above-mentioned technical problems, a pulp mixing device is provided, which solves the problem that in the prior art, the mixing tank has an open top structure, and when pulp is being mixed or the inner wall is being cleaned, a certain amount of pulp is easily splashed out of the open top and lands on the meshing teeth. This causes the drive motor to run and drive the gears to mesh with the meshing teeth, which can easily cause the teeth to jam and affect the rotation effect of the meshing teeth on the scraper.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a pulp mixing device, including a mixing tank with an open top, a scraper ring that slides linearly on the inner wall of the mixing tank, and a rotary lifting mechanism disposed on the open top of the mixing tank. The rotary lifting mechanism further includes a toothed disc rotatably disposed on the cover ring. An inverted L-shaped mounting frame is disposed above the toothed disc and fixedly connected to the cover ring. A drive motor is mounted on the top of the mounting frame, and a power gear meshing with the toothed disc is tightly sleeved on the shaft of the output shaft of the drive motor. The device also includes a suction mechanism for handling paper impurities on the toothed disc.

[0007] The suction mechanism includes an adsorption box installed at the bottom edge of the cover ring and an adsorption head disposed next to the suction head, wherein the adsorption head is connected to the adsorption box;

[0008] The adsorption box includes a box body with one side open and mounted to the bottom of the cover ring by a bracket, a cover body that is detachably mounted to the open end of the box body by bolts, and a filter section built into the box body. A blower is installed on the rear side of the box body, and the suction pipe of the blower enters the inner cavity of the box body and is located below the filter section.

[0009] Preferably, the suction head includes a suction head located above the cover ring, and a suction pipe is fixedly connected between the suction head and the housing.

[0010] Preferably, the filtration section is a filter plate that is fixed in an inclined shape between the inner walls of both sides of the box body, and there is a gap between the lower inclined end of the filter plate and the cover body, in which a filter box fixedly connected to the cover body is disposed.

[0011] Preferably, a spray pipe is provided at the upper inclined end of the filter plate, the spray pipe has a plurality of spray holes, a water pipe connector fixedly connected to the spray pipe is also provided on the box body, and a water collection tank is fixedly connected to the bottom of the box body.

[0012] Preferably, a supply slide is vertically fixed on the wall of the mixing tank, and an impact member that cooperates with the drive motor is elastically slidably arranged on the inner side of the supply slide.

[0013] Preferably, the impact member includes a movable block that slides within the supply slide seat via a slider and a groove. One end of the movable block is in contact with the housing, and a buffer spring is fixed between the other end of the movable block and the innermost inner wall of the supply slide seat.

[0014] Preferably, a transmission column is fixed to the bottom end of the output shaft of the drive motor, a transmission gear is fixed to the bottom end of the transmission column, and a transmission gear plate that meshes with the transmission gear is fixed to the top surface of the movable block.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] (1) By setting up the suction mechanism, the suction head located next to the suction head can effectively and continuously suck up the pulp impurities attached to the toothed disc during the rotation of the toothed disc and pass them into the suction box for centralized storage. This can not only avoid the pulp impurities affecting the rotation effect of the toothed disc, but also facilitate the secondary use of pulp raw materials.

[0017] (2) By setting up the spray pipe, the water pipe joint is connected to the water supply pipe, so that water can be continuously supplied to the spray pipe, and the water is output from the spray hole and washes the pulp on the filter plate, so that the pulp can enter the inside of the filter box for storage more quickly and completely under water flow operation.

[0018] (3) By setting the impact component, when the drive motor is turned on and its output shaft is continuously rotating, the impact component reciprocates elastically contracting inside the slide block and intermittently knocks on the outer wall of the box, which creates a certain vibration effect on the box and filter plate, further accelerating the discharge rate of pulp to the inside of the filter box, so as to prevent pulp from accumulating and clogging on the filter plate.

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0025] Reference Figure 1-3 As shown, a pulp mixing device includes a mixing tank 1 with an open top, a scraper ring 6 that slides linearly on the inner wall of the mixing tank 1, and a rotary lifting mechanism disposed on the open top of the mixing tank 1. The mixing tank 1 has a mixing mechanism built in.

[0026] The rotary lifting mechanism includes a cover ring 2 fixed to the open end of the mixing tank 1, a support frame 4 fixed to the cover ring 2 in an inverted U-shape, and a horizontal plate 5 that slides linearly inside the support frame 4. A connecting rod 7 is fixed between the horizontal plate 5 and the scraper ring 6. A cylinder is installed on the top of the support frame 4. The telescopic end of the cylinder passes through the inside of the support frame 4 and is rotatably connected to the horizontal plate 5.

[0027] The rotary lifting mechanism also includes a gear 8 rotatably mounted on the cover ring 2. The connecting rod 7 is slidably fitted with a limiting sleeve 9 that is fixedly connected to the inner wall of the gear 8. An inverted L-shaped mounting bracket 10 is provided above the gear 8 and is fixedly connected to the cover ring 2. A drive motor 3 is mounted on the top of the mounting bracket 10. The output shaft of the drive motor 3 rotates through the mounting bracket 10 and the cover ring 2 in sequence. The shaft of the output shaft of the drive motor 3 is tightly fitted with a power gear 11 that meshes with the gear 8.

[0028] When in use, the cylinder and drive motor 3 are turned on. The operation of the cylinder can drive the horizontal plate 5, the connecting rod 7 and the scraper ring 6 to move up and down as a whole. This allows the scraper ring 6 to effectively scrape the inner wall of the mixing tank 1. The operation of the drive motor 3 can drive the power gear 11 to continuously mesh with the gear plate 8, providing rotation for the connecting rod 7, the horizontal plate 5 and the scraper ring 6 as a whole. This allows the scraper ring 6 to rotate synchronously during the up and down scraping process, thereby further improving the cleaning effect.

[0029] However, since the mixing tank 1 has an open top structure, when the pulp is being mixed or the inner wall is being cleaned, a certain amount of pulp is very likely to splash out from the open top and land on the toothed disc 8. This can cause the drive motor 3 to run and drive the power gear 11 to mesh with the toothed disc 8, which can easily cause the teeth to jam and affect the rotation effect of the toothed disc 8 on the scraper ring 6.

[0030] Therefore, referring to Figure 2 and Figure 3 As shown, it is worth noting that it also includes a suction mechanism for handling paper impurities on the toothed disc 8.

[0031] The suction mechanism includes an adsorption box installed at the bottom edge of the cover ring 2 and an adsorption head located on the side of the suction head 13, with the adsorption head connected to the adsorption box;

[0032] By using the suction mechanism, the suction head located next to the suction head 13 can effectively and continuously suck up the pulp impurities attached to the toothed disc 8 during its rotation and pass them into the suction box for centralized storage. This not only avoids the pulp impurities affecting the rotation effect of the toothed disc 8, but also facilitates the secondary use of pulp raw materials.

[0033] Furthermore, referring to Figure 2 As shown, it is worth noting that the adsorption box includes a box body 12 with one side open and mounted on the bottom of the cover ring 2 by a bracket, a cover body 18 that is detachably mounted on the open end of the box body 12 by bolts, and a filter section built into the box body 12. A blower (not shown in the figure) is installed on the rear side of the box body 12, and the suction pipe of the blower enters the inner cavity of the box body 12 and is located below the filter section.

[0034] The suction head includes a suction head 13 located above the cover ring 2, and a suction pipe 14 is fixedly connected between the suction head 13 and the box body 12.

[0035] When the blower is turned on, the blower's suction pipe will continuously generate suction force inside the chamber 12, causing the suction head 13 to directly suck up pulp impurities from the toothed disc 8. The pulp impurities are then passed into the chamber 12 through the suction pipe 14 and filtered by the filter section.

[0036] Furthermore, referring to Figure 2 As shown, it is worth noting that the filter section is a filter plate 15 that is fixed in an inclined shape between the inner walls on both sides of the box 12. There is a gap between the lower end of the filter plate 15 and the cover 18. A filter box 17 that is fixedly connected to the cover 18 is provided in the gap, and the filter box 17 is located below the lower end of the filter plate 15.

[0037] With the filter plate 15 and filter box 17, when pulp impurities are introduced into the housing 12 through the dust suction pipe 14, the filter plate 15 can effectively filter and intercept the pulp impurities, so as to prevent the pulp impurities from being directly sucked by the blower and affecting the service life of the blower.

[0038] The filter plate 15 is inclined so that after impurities in the pulp are filtered and intercepted, they can automatically slide down the incline to the inside of the filter box 17 for collection. Afterwards, only the bolts need to be loosened to disassemble the cover 18 from the box 12, and the filter box 17 can be taken out from the inside of the box 12 for manual pulping.

[0039] Furthermore, referring to Figure 2 and Figure 3 As shown, it is worth noting that a spray pipe 16 is provided at the upper inclined end of the filter plate 15. The spray pipe 16 has several spray holes. The box body 12 is also provided with a water pipe connector that is fixedly connected to the spray pipe 16 (not shown). A water collection tank 19 is fixedly connected to the bottom of the box body 12. A valve is built into the water outlet end of the water collection tank 19.

[0040] By setting up the spray pipe 16 and connecting the water pipe connector to the water supply pipe, water can be continuously supplied to the spray pipe 16, so that the water is output from the spray hole and washes the pulp on the filter plate 15, allowing the pulp to enter the filter box 17 for storage more quickly and completely under water flow operation.

[0041] Furthermore, during the process of water being output from the spray pipe 16, the water collection tank 19 can still effectively collect and store the water, facilitating subsequent recycling.

[0042] Furthermore, referring to Figure 3, it is worth noting that a sliding block 20 is vertically fixed on the wall of the mixing tank 1. The top of the sliding block 20 and the side facing the box 12 are open, and an impact member that cooperates with the drive motor 3 is elastically slidably arranged on the inner side of the sliding block 20.

[0043] By setting the impact component, when the drive motor 3 is turned on and its output shaft rotates continuously, the impact component reciprocates elastically and contracts inside the slide block 20, and intermittently knocks on the outer wall of the box 12, which creates a certain vibration effect on the box 12 and the filter plate 15, further accelerating the discharge rate of pulp to the inside of the filter box 17, so as to prevent pulp from accumulating and clogging on the filter plate 15.

[0044] Furthermore, referring to Figure 3 As shown, it is worth noting that the impact component includes a movable block 21 that slides within the supply slide 20 via a slider and a groove. One end of the movable block 21 is in contact with the housing 12, and a buffer spring 22 is fixed between the other end of the movable block 21 and the innermost inner wall of the supply slide 20.

[0045] A transmission column 24 is fixed at the bottom end of the output shaft of the drive motor 3, a transmission gear 25 is fixed at the bottom end of the transmission column 24, and a transmission tooth plate 23 that meshes with the transmission gear 25 is fixed on the top surface of the movable block 21.

[0046] When the drive motor 3 is turned on and its output shaft rotates continuously, the transmission gear 25 can intermittently mesh with the transmission gear plate 23. During this period, when the transmission gear 25 meshes with the transmission gear plate 23, the movable block 21 is forced to contract towards the inside of the slide block 20 and compress the buffer spring 22. When the transmission gear 25 rotates to a state where it is not meshing with the transmission gear plate 23, the movable block 21 can quickly reset under the elastic force of the buffer spring 22 and impact the outer wall of the housing 12.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
