Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of pulp processing technology, and more specifically, to an eccentric rotor hydraulic pulper. Background Technology

[0002] In industries such as papermaking and recycling, pulpers are key equipment used to decompose waste paper and waste fiber materials into uniform pulp. Their performance directly affects product quality and production efficiency. Traditional pulpers have the following problems during long-term use: (1) Poor mixing effect. The existing pulper's mixing device is simple in design, and the distribution and movement of the mixing blades are unreasonable, resulting in uneven mixing of materials in the processing tank. This causes some materials to be unable to be fully broken down, affecting the quality stability of the pulp, and prolonging the pulping time, thus reducing production efficiency; (2) During the pulping process, materials tend to accumulate and solidify at the bottom of the processing tank. This is especially prominent when processing raw materials containing viscous substances. This not only hinders the normal operation of the pulper and causes equipment failure, but also requires frequent shutdowns for cleaning, increasing maintenance costs. In addition to production interruption time, the discharge port is often blocked due to material solidification and agglomeration, which affects the smooth discharge of materials and further reduces production efficiency; (3) As the pulping process continues, the material will gradually adhere to the inner wall of the processing barrel, forming an adhesive layer that is difficult to remove. This will not only affect the mixing effect of the pulper, but also lead to material waste and increase production costs. Traditional pulpers lack effective wall scraping devices and cannot remove the material on the barrel wall in time, which causes the equipment operating efficiency to gradually decrease; (4) The processing barrel of traditional pulpers is usually a closed structure, and it is difficult for operators to observe the pulping situation in the barrel in real time and adjust the operating parameters of the equipment in time. This makes it difficult to accurately control the pulping process according to the characteristics of the material and the processing requirements, which increases the difficulty of production management and affects the stability of product quality.

[0031] like Figures 1-4 As shown, it illustrates an eccentric rotor hydraulic pulper of this disclosure, comprising:

[0032] Processing barrel 1, with a feed inlet 2 at the upper end of processing barrel 1;

[0033] Mixing feed assembly 3 is disposed inside processing barrel 1;

[0034] Anti-solidification processing component 4 is installed at the bottom of the processing barrel 1;

[0035] The mixing and feeding assembly 3 includes a dividing plate 3-1, which is disposed inside the processing barrel 1. A stirring motor 3-2 is disposed on the upper end of the processing barrel 1. The output end of the stirring motor 3-2 is inserted into the processing barrel 1. An extension rod 3-3 is disposed at the bottom of the output end of the stirring motor 3-2. A drive sleeve 3-4 is disposed at the bottom of the extension rod 3-3. A stirring frame 3-5 is disposed on opposite sides of the drive sleeve 3-4. A stirring blade 3-6 and a wall scraper 3-7 are disposed at opposite ends of the stirring frame 3-5, respectively. The lower end of the dividing plate 3-1 is provided with... A drive cover 3-8 is provided, and a motor frame 3-9 is provided inside the drive cover 3-8. An adjustment motor 3-10 is provided inside the motor frame 3-9. The output end of the adjustment motor 3-10 passes through the dividing plate 3-1. A stabilizing sleeve 3-11 is provided at the output end of the adjustment motor 3-10. An opening and closing plate 3-12 is fitted on the stabilizing sleeve 3-11. A connecting port 3-13 is provided on the opening and closing plate 3-12. A drop port 3-14 is provided on the dividing plate 3-1. The position, size and structure of the connecting port 3-13 and the drop port 3-14 correspond to each other.

[0036] The anti-solidification processing component 4 includes a stabilizing disc 4-1, a mixing motor 4-2 is embedded inside the stabilizing disc 4-1, the output end of the mixing motor 4-2 is positioned downwards, a mixing sleeve 4-3 is provided at the output end of the mixing motor 4-2, and mixing blades 4-4 are provided on the side wall of the mixing sleeve 4-3.

[0037] In some examples, the dividing plate 3-1 can divide the processing barrel 1 into a mixing area (upper end of the processing barrel 1) and an anti-coagulation area (lower end of the processing barrel 1). After the stirring motor 3-2 drives the extension rod 3-3 to rotate, the driving sleeve 3-4 can rotate on its own. The stirring blade 3-6 on the stirring frame 3-5 can stir the mixture, and the scraper blade 3-7 can scrape the inside of the processing barrel 1 to prevent the material from sticking to the inner wall of the processing barrel 1. The adjusting motor 3-10 is installed in the motor frame 3-9 in the drive cover 3-8. After the adjusting motor 3-10 drives the stabilizing sleeve 3-11 to rotate, it can drive the opening and closing plate 3-12 to rotate. The connecting port 3-13 on the opening and closing plate 3-12 is aligned with the drop port 3-14 on the dividing plate 3-1, and the material falls from above the dividing plate 3-1 to the lower area through the drop pipe 6.

[0038] A mixing motor 4-2 is embedded inside the stabilizing plate 4-1, with the output end of the mixing motor 4-2 facing downwards. During installation, it is necessary to ensure that the mixing motor 4-2 can work normally and is tightly connected to the stabilizing plate 4-1. A mixing sleeve 4-3 is installed at the output end of the mixing motor 4-2, and a suitable connection method (such as key connection or threaded connection) is used to ensure that the mixing sleeve 4-3 is firmly connected to the output end of the mixing motor 4-2. A mixing blade 4-4 is installed on the side wall of the mixing sleeve 4-3, ensuring that the mixing blade 4-4 is firmly installed and can rotate normally under the drive of the mixing sleeve 4-3, so as to achieve mixing and stirring of the material at the bottom of the processing barrel 1 and prevent solidification.

[0039] like Figures 1-4 As shown, in this embodiment, the lower end face of the opening and closing disc 3-12 is provided with a drive groove 3-15, the stabilizing sleeve 3-11 is fixedly embedded in the drive groove 3-15, the bottom surface of the stirring motor 3-2 is provided with a mounting plate 3-16, the mounting plate 3-16 is set on the top of the processing barrel 1, and the stirring motor 3-2 and the mounting plate 3-16 are connected by bolts.

[0040] In some examples, ...

[0041] For example, such as Figure 2 As shown, the inner bottom surface of the processing barrel 1 is provided with a discharge port 4-5, and a discharge cover 4-6 is provided on the discharge port 4-5.

[0042] In some examples, a discharge hood 4-6 is installed on the discharge port 4-5 to ensure that the discharge hood 4-6 is tightly connected to the discharge port 4-5. This can be achieved by welding or sealing to prevent material leakage and facilitate material discharge.

[0043] For example, such as Figure 2 As shown, the bottom surface of the processing barrel 1 is provided with several supporting feet 5. The multiple supporting feet 5 are equidistantly arranged at the bottom edge of the processing barrel 1. The lower end surface of the dividing plate 3-1 is provided with a drop pipe 6, and the drop pipe 6 is sealed and inserted into the drop outlet 3-14.

[0044] In some examples, the support foot 5 is used to lift the processing barrel 1 so that the discharge hood 4-6 on the discharge port 4-5 can discharge the material, and the drop pipe 6 is used to connect to the drop port 3-14 to guide the mixed material to fall from the drop port 3-14.

[0045] For example, such as Figure 2 As shown, the side wall of the processing barrel 1 is provided with a viewing glass 7 and an observation port 8. The position of the observation port 8 corresponds to that of the viewing glass 7. The outer side wall of the scraper blade 3-7 is an arc-shaped structure, and the scraper blade 3-7 is in contact with the inner side wall of the processing barrel 1.

[0046] In some examples, an observation port 8 is provided on the side wall of the processing barrel 1. The position of the observation port 8 should be convenient for the operator to observe the inside of the processing barrel 1.

[0047] First, the material to be pulped is added into the processing tank 1 through the feed inlet 2 at the top. The stirring motor 3-2 is then started, driving the extension rod 3-3, the drive sleeve 3-4, the stirring frame 3-5, the stirring blades 3-6, and the scraper blades 3-7 to rotate, thus initially mixing the added material. Depending on the processing requirements of the material, during the mixing process, the adjusting motor 3-10 is started to offset the connecting port 3-13 from the drop port 3-14, closing the material drop channel. After mixing is complete, the adjusting motor 3-10 is started again, driving the stabilizing sleeve 3-11 and the opening / closing disc 3... Rotate -12 to align the connecting port 3-13 on the opening and closing plate 3-12 with the drop port 3-14 on the dividing plate 3-1. The material falls from above the dividing plate 3-1 to the lower area through the drop pipe 6. During the material processing, start the mixing motor 4-2. The mixing motor 4-2 drives the mixing sleeve 4-3 and the mixing blade 4-4 to rotate, stirring and mixing the material at the bottom of the processing barrel 1 to prevent the material from solidifying and to ensure the uniformity and flowability of the material. After the material processing is completed, open the discharge hood 4-6 to discharge the processed material from the discharge port 4-5 for subsequent processing or collection.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
