Description

Technical Field

[0001] The utility model relates to a cleaning mechanism, in particular to a cleaning mechanism used in a double-shaft mixer for hazardous waste. Background Art

[0002] The number of hazardous wastes discharged during industrial production processes is increasing. For the sake of environmental protection and health, hazardous wastes need to be treated. Some of these hazardous wastes form fly ash after combustion and are then transported and dumped into a hazardous waste treatment system for treatment. The current method of transporting fly ash is to dump the bagged fly ash into a spiral feeding mechanism, which is then transported to a belt conveyor mechanism by the spiral feeding mechanism. The belt conveyor mechanism then tilts the fly ash upward and transports it to a twin-shaft mixer for mixing with other additives. The waste after mixing is output through a discharge conveyor belt below the discharge port.

[0003] Since the fly ash waste is not processed continuously in the twin-shaft mixer, the twin-shaft mixer will be shut down after processing a batch of fly ash waste. The time for the next start-up of the twin-shaft mixer is uncertain. Therefore, waste will often accumulate on the mixing shaft or in the corners during the shutdown period of the twin-shaft mixer. If it is not cleared, it will easily increase the operating load of the equipment in the long run.

[0004] At present, in order to remove the accumulated waste, it is usually done by manually inserting a water pipe through the observation window for flushing. Since there is a small space between the discharge port of the twin-shaft mixer and the discharge conveyor belt, in order to place a water tank loaded with cleaning water at the discharge port, the discharge output belt needs to be moved, so that a water tank or a bucket can be placed on the ground where the discharge conveyor belt was originally placed. During the cleaning process, it is also necessary to replace the empty water tank or bucket to load a large amount of cleaning water. This method is not only time-consuming and labor-intensive, but also the cleaning water is likely to overflow and dirty the ground during the replacement of the water tank or bucket, which needs to be cleaned up later, which brings a large workload to the operator.

[0005] In addition, since fly ash is a fine granular object produced during the combustion process and is relatively light in weight, and the belt conveyor mechanism is inclined and the surface of the belt is flat, the fly ash squeezed into the input end of the belt conveyor mechanism is easily unable to follow the belt conveyor mechanism in time and be tilted upward, causing fly ash accumulation on the input end of the belt conveyor mechanism. The increased fly ash will fall off the belt surface along both sides of the input end of the belt conveyor mechanism, affecting the operation.

[0006] Currently retrieved Chinese patent "A concrete mixer cleaning mechanism", publication number CN215395978U

[0007] It includes a support frame, a mixing drum and a first driving mechanism. A plurality of water spray ports and a plurality of blocks are provided on the upper part of the mixing drum. The first driving mechanism is slidably connected to the mixing drum. The block drives the block to slide. The water spray ports correspond to the blocks one by one. When the blocks are extended, they block the corresponding water spray ports. The blocks are arranged in the water spray ports. Although the patent can clean the inner wall and the mixing shaft of the mixing drum after use, and can prevent the water in the water spray port from entering the mixing drum during the mixing process, resulting in excessive water in the concrete and affecting the quality of the concrete, the patent cannot realize the cleaning of the inside of the double-shaft mixer and the treatment of the cleaning water.

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] like Figure 1 , 2 As shown, the cleaning mechanism of the double-shaft mixer for hazardous waste of the utility model comprises a frame 1 and a belt conveyor mechanism 2 obliquely arranged on the frame, the output end of the belt conveyor mechanism is connected to the first feed port of the double-shaft mixer A1, so that the hazardous waste at the output end of the belt conveyor mechanism is input into the double-shaft mixer, and other feed ports are also provided on the double-shaft mixer A1 to add materials for treating the waste, and a plurality of water nozzles A2 connected to a tap water pipe are provided on the top of the housing of the double-shaft mixer, and the water nozzles can be densely distributed on a water pipe to discharge water. A hole is formed, or directly formed by a shower head. A discharge port A3 is provided at the lower part of the twin-shaft mixer (the discharge port is opened and closed by a manual or electric valve), a discharge output belt A4 is provided below the discharge port, a water storage bag A5 is detachably connected to the discharge port, the water storage bag is a plastic bag that does not leak water, a filter bag A6 is provided inside the water storage bag A5, the filter bag can be a cotton bag, the bag opening of the filter bag is fastened to the discharge port by a clamp, and the bag opening of the water storage bag is fastened to the discharge port by a clamp; the volume of the water storage bag is much larger than that of the filter bag.

[0029] The bag openings of the water storage bag A5 and the filter bag A6 are both sealed to cover the discharge port A3, and the bottoms of the water storage bag and the filter bag are supported above the surface of the discharge output belt (the discharge output belt stops working at this time). The volume of the filter bag can be 10-30 kg of water, and the volume of the water storage bag can be 50-300 kg. Since the water storage bag and the filter bag are both supported and placed on the discharge conveyor belt, and the water storage bag can be spread over a larger area, the extrusion pressure on the plastic of the water storage bag is smaller, and the water storage bag is not easily damaged; a drain port A7 is provided on the water storage bag, and the drain port is connected to the water nozzle through a pipeline A8 and a water pump A9 to guide the water in the water storage bag into the water nozzle through the water pump and the pipeline.

[0030] In order to better shake off the waste in the mixer, a vibration motor A10 is installed on the outer surface of the casing of the above-mentioned double-shaft mixer. The vibration motor A10 can vibrate the casing of the double-shaft mixer to make the sticky waste easier to fall off.

[0031] In order to facilitate the introduction of waste materials into the first feeding port of the twin-shaft mixer, a material guide inclined plate A11 is provided between the output end of the belt conveyor mechanism and the first feeding port.

[0032] After the mixing and stirring work of the twin-shaft mixer is completed, the discharge port at the bottom of the twin-shaft mixer is opened (through a manual or electric valve) to discharge the hazardous waste and output it through the discharge conveyor belt. After the hazardous waste in the twin-shaft mixer is completely discharged, the filter bag and the water storage bag are put on the discharge port in turn and tightened with a clamp. The water nozzle, the water pump and the water storage bag drainage port are connected through a pipeline. Initially, water is supplied through the tap water connected to the water nozzle. After the tap water is supplied for some time, the water pump is started. The water pump continuously transports the water in the water storage bag to the water nozzle. The water nozzle sprays water into the twin-shaft mixer, and then from the discharge port, it is filtered through the filter bag and enters the water storage bag. The water in the water storage bag returns to the water nozzle through the pipeline and the water pump. This is repeated for a period of time, thereby completing the cleaning of the twin-shaft mixer; after the cleaning is completed, the water pump is stopped, the connection between the pipeline and the water nozzle is removed, and the outlet of the pipeline is led into the drainage ditch.

[0033] The utility model has a simple structure. During use, there is no need to move a heavy discharging conveyor belt, replace a water tank or a water bucket, and overflow of cleaning water will not occur during the replacement process.
