Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, and specifically relates to a cleaning device. Background Technology

[0002] Palm fiber is a natural plant fiber widely used in many fields, mainly derived from the fruit bunches of oil palm and the shells of coconut trees. This type of fiber possesses high mechanical strength, good air permeability and moisture absorption, and strong resistance to seawater and other corrosive environments. Therefore, it shows promising application prospects in agriculture and horticulture (such as plant cultivation substrates), furniture and home furnishings (such as mattresses and cushions), industrial materials (such as composite material reinforcing agents and filter media), and handicrafts and decorations.

[0003] The extraction of palm fiber involves preliminary processing, cooking or fermentation, mechanical separation, washing, and drying of the main raw materials, such as fruit bunches and shells. Washing is a crucial step, removing residual pulp, potassium ions, and other impurities to improve fiber cleanliness. Traditional washing methods often employ pool washing, where palm fibers are directly immersed in a washing tank for soaking and rinsing. However, this method suffers from incomplete washing, low efficiency, and high labor intensity, limiting the large-scale processing of palm fiber. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cleaning device includes a cleaning tank, the bottom of which slopes from its inlet end to its outlet end, with the bottom at the inlet end being higher than the bottom at the outlet end. A plurality of actuating rollers are arranged inside the cleaning tank, and the surfaces of the actuating rollers are provided with rake teeth for driving material to be transported to the outlet end of the cleaning tank. The outlet end of the cleaning tank is provided with a discharge auger.

[0007] The technical solution is further configured such that, along the direction from the feed end to the discharge end of the cleaning tank, several actuating rollers are arranged in parallel and at intervals, and the rotation direction of the several actuating rollers is the same.

[0008] The technical solution is further configured such that the rake teeth are configured as a bent structure, and the bending direction is opposite to the rotation direction of the agitator roller.

[0009] The technical solution is further configured such that a baffle is provided at the bottom of the cleaning tank at the discharge end, and a material channel is formed between the baffle and the discharge end of the cleaning tank, and the discharge auger is provided at the material channel.

[0010] The technical solution is further configured such that an impurity channel is formed between the end of the baffle and the side wall of the cleaning tank, and a drainage water tank is formed at the bottom of the cleaning tank at the discharge end, which is connected to the impurity channel. The side wall of the cleaning tank is provided with a guide plate for sealing the drainage water tank. The guide plate and the drainage water tank form a drainage water chamber, and the drainage water chamber is provided with a sewage discharge outlet.

[0011] The technical solution is further configured such that the inlet end of the cleaning tank is provided with a cleaning water inlet, the outlet end of the cleaning tank is provided with a cleaning water outlet, and the cleaning water outlet is connected to the material channel.

[0012] The technical solution is further configured to include an extrusion cylinder, wherein an extrusion auger is provided inside the extrusion cylinder, the feed end of the extrusion cylinder is connected to the discharge end of the cleaning tank, and the discharge end of the extrusion cylinder is located at a higher position than its feed end.

[0014] The technical solution is further configured such that the pitch of the extrusion auger decreases from large to small in the direction from the feed end to the discharge end of the extrusion cylinder.

[0015] The beneficial effects of this utility model are:

[0016] 1. The bottom of the cleaning tank is set as an incline, so that the material and cleaning water will naturally slide towards the discharge end under the action of gravity during the cleaning process; by setting up agitator rollers and rake teeth, pressure can be applied to the material to make it sink into the cleaning water and be thoroughly cleaned, and the material can be pushed to move towards the discharge end of the cleaning tank, which improves the efficiency of the cleaning operation and reduces the labor intensity of the operators; the inclined tank bottom combined with the rake teeth forms a composite conveying mechanism of mechanical propulsion and gravity sliding.

[0017] 2. By setting up an extrusion cylinder, an extrusion auger, and an extrusion water discharge cylinder, the cleaned material is lifted and extruded.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0025] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0026] According to an embodiment of this utility model, a cleaning device is provided. Please refer to [link / reference]. Figures 1 to 4 The system includes a cleaning tank 1, the bottom of which is inclined from the feed end to the discharge end, and the bottom of the tank at the feed end is higher than the bottom of the tank at the discharge end. Several actuating rollers 2 are arranged inside the cleaning tank 1. The surface of the actuating rollers 2 is provided with rake teeth 17 for driving the material to be transported to the discharge end of the cleaning tank 1. The discharge end of the cleaning tank 1 is provided with a discharge auger 3.

[0027] Understandably, the bottom of the washing tank 1 is designed as an incline, allowing the material and washing water to naturally slide towards the discharge end under gravity during the washing process. By incorporating the agitator roller 2 and rake teeth 17, pressure is applied to the material, immersing it in the washing water for thorough cleaning, while simultaneously propelling the material towards the discharge end of the washing tank 1. This improves washing efficiency and reduces the workload for operators. The inclined tank bottom combined with the rake teeth 17 forms a composite conveying mechanism of mechanical propulsion and gravity sliding, effectively reducing the driving force required to rely solely on the rake teeth 17, thus reducing equipment energy consumption, while simultaneously increasing the speed and continuity of material movement within the washing tank 1.

[0028] In one cleaning apparatus of this embodiment, please refer to Figures 1 to 4 Along the direction from the feed end to the discharge end of the cleaning tank 1, several actuating rollers 2 are arranged in parallel and at intervals, and the rotation direction of the several actuating rollers 2 is the same.

[0029] Furthermore, the agitator roller 2 is driven to rotate by a motor. Several agitator rollers 2 can be driven by the same motor or by different motors.

[0030] Understandably, the washing water flows from the feed end to the discharge end of the washing tank 1, and the agitator roller 2 rotates counterclockwise. When the agitator roller 2 rotates, it drives the rake teeth 17 on it to rotate synchronously. The rotation of the rake teeth 17 can both move the material forward and push the material that floats to the surface back underwater. In this process of floating and pressing down, the material is continuously transported forward in the washing water.

[0031] In one cleaning apparatus of this embodiment, please refer to Figures 1 to 4 The rake teeth 17 are configured as a bent structure, and the bending direction is opposite to the rotation direction of the agitator roller 2.

[0032] Furthermore, the rake tooth 17 includes a connecting end and a actuating end that are connected to each other at a certain angle. The connecting end extends radially along the actuating roller 2 and is connected to the roller body of the actuating roller 2. The actuating end extends in a direction away from the roller body of the actuating roller 2.

[0033] Understandably, as the rake teeth 17 rotate with the agitator roller 2, the angle between the rake teeth 17 and the horizontal plane continuously changes. When the agitator end is at a small upward angle or close to horizontal, it facilitates pressing the material into the washing water. As the agitator end continues to rotate, gradually increasing its angle with the horizontal plane, it lifts, tumbles, and pushes the material, promoting full contact between the material and the washing water, with most of the material being conveyed to the next agitator roller 2. A small portion of the material continues to rotate with the agitator end, and the angle further changes, achieving a "throwing" action, causing the material to detach from the rake teeth 17 and fall into the washing water, repeating the above process. This dynamic angle change mechanism significantly improves the washing effect.

[0034] In one cleaning apparatus of this embodiment, please refer to Figures 1 to 4 A baffle 14 is provided at the bottom of the cleaning tank 1 at the discharge end, and a material channel is formed between the baffle 14 and the discharge end of the cleaning tank 1. The discharge auger 3 is provided at the material channel.

[0035] Furthermore, the baffle 14 is located in the middle of the bottom of the tank. During the cleaning process, impurities such as mud and sand generated slide down the inclined bottom of the tank to the baffle 14. The baffle 14 can block impurities from entering the material channel and prevent impurities from being discharged from the cleaning tank 1 along with the cleaned material through the discharge auger 3.

[0036] Furthermore, the baffle 14 is composed of two adjacent sub-baffles at a certain angle, forming a "V" or "human" shaped structure. This structural design guides the flow of impurities, causing them to flow to the end position of the baffle 14.

[0037] In one cleaning apparatus of this embodiment, please refer to Figures 1 to 4 An impurity channel is formed between the end of the baffle 14 and the side wall of the cleaning tank 1. The bottom of the tank at the discharge end of the cleaning tank 1 is recessed to form a discharge water tank 6 that communicates with the impurity channel. The side wall of the cleaning tank 1 is provided with a guide plate 16 for sealing the discharge water tank 6. The guide plate 16 and the discharge water tank 6 form a discharge water chamber. The discharge water chamber is provided with a sewage discharge port 7.

[0038] Furthermore, the discharge auger 3 is positioned between the guide plates 16 on both sides, through which the material entering the material channel is discharged.

[0039] Understandably, baffle 14 separates the material channel from the impurity channel, achieving automatic separation of materials and impurities and improving the cleanliness of the cleaned material. The discharge water chamber is a semi-enclosed structure used to centrally collect some of the cleaning water and impurities.

[0040] In one cleaning apparatus of this embodiment, please refer to Figures 1 to 4 The cleaning tank 1 has a cleaning water inlet 4 at the feed end and a cleaning water outlet 5 at the discharge end, which is connected to the material channel.

[0041] Furthermore, the feed end of the cleaning tank 1 is provided with a feed inlet 15. The material enters the cleaning tank 1 through the feed inlet 15, and the cleaned material is output under the action of the discharge auger 3.

[0042] Furthermore, the cleaning device may include two layers of cleaning tanks 1 stacked one on top of the other, each layer of cleaning tank 1 operating independently, and the feed inlets 15 of the two layers of cleaning tanks 1 may be connected or independent of each other.

[0043] Understandably, cleaning water at a certain temperature is injected into the cleaning tank 1 through the cleaning water inlet 4, using warm or hot water to enhance the cleaning ability and efficiency. The cleaning water flows in from a higher position (feed end) and flows down the inclined bottom of the tank to a lower position (discharge end), carrying impurities such as mud and debris towards the discharge end. The cleaning water containing impurities is discharged through the wastewater outlet 7, while the cleaning water without impurities is discharged through the cleaning water outlet 5, allowing for recycling and resource conservation. In other words, water is supplied from one end and drained from the other, creating a flowing water flow inside the cleaning tank 1, which has a certain pushing effect on the materials.

[0044] Specifically, the temperature of the cleaning water can be adjusted according to the actual working conditions. The temperature of warm water can be selected from 30℃ to 50℃; the temperature of hot water can be selected from 60℃ to 80℃.

[0045] In one cleaning apparatus of this embodiment, please refer to Figures 1 to 5 It also includes an extrusion cylinder 8, which is equipped with an extrusion auger 9. The feed end 11 of the extrusion cylinder is connected to the discharge end of the cleaning tank 1, and the discharge end 12 of the extrusion cylinder is located higher than the feed end 11.

[0046] Understandably, the feed end 11 of the extrusion cylinder is directly connected to the discharge end of the washing tank 1 (i.e., the discharge end of the discharge auger 3), allowing the washed material to automatically enter the extrusion and dewatering process without intermediate transfer. This achieves a continuous and integrated operation process of "washing—discharge—extrusion—output," reducing manual intervention. The extrusion cylinder 8 and the extrusion auger 9 are arranged at an upward inclination. The material needs to overcome gravity to be conveyed upward, which slows down the movement speed and prolongs the residence time in the extrusion cylinder 8, which is conducive to the full extraction of moisture.

[0047] In one cleaning apparatus of this embodiment, please refer to Figures 1 to 5 The bottom periphery of the extrusion cylinder 8 is provided with an extrusion water discharge cylinder 10, and the extrusion cylinder 8 is provided with a through hole communicating with the extrusion water discharge cylinder 10.

[0048] Understandably, the extrusion auger 9 lifts and extrudes the cleaned material. The extrusion water generated by the extrusion auger 9 extruding the material flows into the extrusion water discharge cylinder 10 through the through hole. The bottom of the extrusion water discharge cylinder 10 is provided with an extrusion water discharge port 13. The extrusion water is discharged from the extrusion water discharge port 13. The extruded material is discharged from the discharge end 12 of the extrusion cylinder.

[0049] In one cleaning apparatus of this embodiment, please refer to Figures 1 to 5From the feed end 11 to the discharge end 12 of the extrusion cylinder, the pitch of the extrusion auger 9 gradually decreases. This structural design allows the material to be subjected to gradually increasing mechanical pressure during the conveying process, squeezing out the residual washing water in the material and achieving physical dehydration. This significantly reduces the moisture content of the material, which is beneficial for further processing.
