Description

Technical Field

[0001] This utility model relates to the field of wood chip rinsing, and more specifically, to a mechanism for efficient rinsing of wood chips. Background Technology

[0002] Wood chip washing is an important step in the wood processing and pulp production process. In the pulping process, wood is first cut into small pieces or wood chips, and then converted into pulp by chemical or mechanical methods. The main purpose of wood chip washing is to remove impurities, dust, bark residue and other unwanted substances from the surface of the wood chips to ensure the efficiency of the subsequent pulping process and the quality of the pulp.

[0003] Existing wood chip rinsing methods mostly involve soaking in a water tank or simple agitation, resulting in poor cleaning effects. Static soaking or simple agitation makes it difficult for the wood chips to rub against each other and come into vigorous contact with the water flow, making it difficult to remove firmly attached impurities and resulting in incomplete cleaning. How to invent a high-efficiency wood chip rinsing mechanism to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-efficiency wood chip rinsing mechanism, which aims to improve the existing wood chip rinsing methods, which mostly use water tank soaking or simple stirring, resulting in poor cleaning effect. Static soaking or simple stirring makes it difficult for the wood chips to rub against each other sufficiently and come into vigorous contact with the water flow, making it difficult to remove firmly attached impurities and resulting in incomplete cleaning.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a high-efficiency rinsing mechanism for wood chips, including a rinsing tank and further comprising: a reciprocating agitation mechanism: the reciprocating agitation mechanism is disposed inside the rinsing tank, and the reciprocating agitation mechanism can drive the wood chips to agitate inside the rinsing tank, thereby improving the rinsing effect; and an air jet mechanism: the air jet mechanism is disposed on the side wall of the rinsing tank, and the air jet mechanism can spray air onto the reciprocating agitation mechanism to prevent the wood chips from clogging.

[0007] Preferably, the reciprocating disturbance mechanism includes a conveyor belt inside the rinsing tank.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example, refer to Figures 1-2 A high-efficiency rinsing mechanism for wood chips includes a rinsing tank 1 and further includes: a reciprocating agitation mechanism 2: the reciprocating agitation mechanism 2 is disposed inside the rinsing tank 1, and the reciprocating agitation mechanism 2 can drive the wood chips to agitate inside the rinsing tank 1 to improve the rinsing effect; and an air jet mechanism 3: the air jet mechanism 3 is disposed on the side wall of the rinsing tank 1, and the air jet mechanism 3 can spray air onto the reciprocating agitation mechanism 2 to prevent the wood chips from clogging.

[0019] The reciprocating disturbance mechanism 2 includes a conveyor belt 200 installed inside the rinsing tank 1. Two sets of rotating shafts 204 are connected to the outer wall of the rinsing tank 1 via bearings. Two sets of sealing grooves are opened on the front side wall of the rinsing tank 1. Bearings are fitted onto the outer walls of both sets of rotating shafts 204, and these bearings cooperate with the inner walls of the sealing grooves to ensure the sealing of the rotating shafts 204 and prevent leakage from the rinsing tank 1. Conveyor rollers 203 are fitted onto the outer walls of both sets of rotating shafts 204. The conveyor belt 200... The conveyor belt 200 is fitted onto the outer wall of two sets of conveyor rollers 203. Multiple sets of disturbance plates 201 are provided on the outer wall of the conveyor belt 200. One end of each of the two sets of rotating shafts 204 is provided with a driven pulley 205 and a driving pulley 207. A belt 206 is fitted onto the outer wall of the driven pulley 205 and the driving pulley 207. A support plate 209 is provided on the side wall of the rinsing tank 1. A motor 208 is provided on the side wall of the support plate 209. The output end of the motor 208 is connected to the side wall of the driving pulley 207.

[0020] One end of the disturbance piece 201 is bent, and multiple sets of slots 202 are opened on the side wall of the disturbance piece 201.

[0021] It should be noted that the disturbance plate 201 is bent to form a structure similar to a "rake", which makes it easier to pick up and lift the wood chips. The slot 202 is used to reduce the overall weight of the disturbance plate 201, while also being able to better grip the wood chips and increase friction.

[0022] The jet mechanism 3 includes a jet pipe 300 provided on the rinsing tank 1. The side wall of the jet pipe 300 is provided with multiple sets of jet nozzles 301. The jet nozzles 301 cooperate with the slot 202. One end of the jet pipe 300 is provided with a fixed pipe 302. One end of the fixed pipe 302 is provided with an air supply pipe 304. A fixed plate 303 is sleeved on the outer wall of the fixed pipe 302. One end of the fixed plate 303 is connected to the side wall of the rinsing tank 1.

[0023] It should be noted that the jet nozzle 301 is aimed at the conveyor belt 200 and the disturbance plate 201, and is matched with the position of the slot 202, which can prevent wood chips from getting tangled on the disturbance plate 201.

[0024] Working Principle: When rinsing wood chips in the rinsing tank 1, the motor 208 starts, driving the two rotating shafts 204 and the conveyor roller 203 to rotate slowly and synchronously via the driving pulley 207, belt 206, and driven pulley 205. The conveyor belt 200 then moves, and the multiple sets of agitators 201 mounted on it move accordingly. When the agitators 201 reach the bottom of the rinsing tank 1, their bent structure "raks up" or "catch" the wood chips at the bottom. As the conveyor belt 200 moves, the wood chips are lifted from the water by the agitators 201. When the agitators 201 reach the top and pass the conveyor roller 203, the wood chips detach from the agitators 201 under gravity and are thrown back into the water. This continuous "lifting-scooping-throwing" process violently agitates the wood chips in all areas of the tank, causing them to move between each other and between different parts of the tank. The water generates strong friction and scouring, thoroughly washing away impurities adhering to its surface. Due to their higher density, the washed-off impurities settle at the bottom of the box (which can be cleaned periodically). When the conveyor belt 200 is working, the jet mechanism 3 operates. Compressed air enters from the air supply pipe 304 and is ejected at high speed from multiple jet nozzles 301 through the jet pipe 300. The airflow is directly sprayed onto the surface of the passing disturbance plate 201 and the conveyor belt 200. The high-speed airflow can effectively blow off the wood chips stuck at the bend of the disturbance plate 201; and blow off and remove the fibers wrapped around the hinge of the disturbance plate 201 and the conveyor belt. By blowing air through the slots 202 on the disturbance plate 201, the debris accumulated in the slots and on the back can be cleaned. This process is carried out in each cycle, ensuring that the working parts are always clean and avoiding the accumulation of wood chips and fibers, thereby effectively preventing blockages.

[0025] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
