Description

Primary Crusher for Food Waste Treatment

technical field

The invention relates to a garbage treatment device, in particular to a first-stage crusher for kitchen garbage treatment, which is used in a pretreatment crushing and pulping section of kitchen garbage.

Background technique

Food waste includes food processing waste (kitchen waste) and food residue (swill) produced by families, schools, canteens, and catering industries. Currently, there are special treatment equipment for reprocessing and utilization of food waste.

The food waste should be roughly sorted before being processed, and then the coarsely sorted food waste should be preliminarily crushed through the primary crusher to separate the light substances and heavy impurities in the food waste to achieve the primary pulp. effect, and then transported to the next process. Since food waste is a mixture of perishable organic waste, light debris (plastic bags, rags, straws, etc.) The adhesion is serious, and must be broken up vigorously, and it is not suitable to be completely crushed. At the same time, there are easily entangled objects (such as ropes, cloth strips, plastic bags, etc.) with a length greater than 20cm in the garbage, which need to be chopped. At present, the industry is using crushers with high operating speed, serious wear and tear, and only a single crushing function, and all materials are crushed, which is not conducive to the complete separation of debris, and becomes a size separation, making it difficult to completely harmless disposal of perishable organic matter. , At the same time, the easily entangled objects need to be cut off, otherwise it is easy to entangle the equipment, resulting in serious equipment failure and high maintenance rate, which brings difficulties to the subsequent process. In addition, the incoming time of food waste is generally relatively concentrated, and the processing capacity is large within a period of time, so the crusher must be able to realize continuous discharge processing.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in Figures 1 to 5, the primary crusher used for the treatment of kitchen waste in this embodiment includes a frame 1, and the primary crusher is divided into a feeding section A, a crushing section B and a discharging section from right to left. There are three sections of section C, a main shaft 2 is set up along the length direction in the frame 1, and a main shaft bearing 8 for supporting the main shaft 2 is provided at the left and right ends of the frame 1, and a feeding screw is provided on the part of the main shaft 1 that is in the feeding section. 21. There is a feeding port 11 above the right end of the frame 1 corresponding to the position of the feeding screw 21. The material enters from the feeding port 11 and is conveyed by the feeding screw 21 and then smoothly enters the crushing section B. The crushing section B is provided with an opposite The rotating outer drum 3 and the crushing blade group 4, the part of the main shaft 2 located in the crushing section B is a broken pinion shaft 22 with an enlarged diameter, and the right end of the broken pinion shaft 22 is conically connected with the feeding section of the main shaft 2 The diameter of the bottom diameter of the broken pinion shaft 22 is 480 mm. The broken blade group 4 includes a plurality of toothed blades, and the toothed blades are arranged in multiple rows along the axial direction of the surface of the main shaft 2 to form the broken pinion shaft 22. The tooth top diameter is 620mm, which can effectively avoid material winding. The outer drum 3 is rotatably sleeved outside the breaking gear shaft 22, so that a crushing cavity is formed between the outer drum 3 and the crushing blade group of the breaking gear shaft 22. The outer drum 3 has a cylinder diameter of 1000mm and a length of 3000mm. A tugwheel mechanism 5 for supporting and driving the outer roller 3 is provided under the main shaft 2 of the frame 1. The tugwheel mechanism 5 is connected with the power mechanism, and the outer roller 3 is equipped with a tugwheel mechanism The outer ring gear 32 meshed with the gears on 5, the tugwheel mechanism drives the outer drum to rotate through the gear transmission, the speed of the outer drum 3 is set at 10-20YPM, and there are multiple inclined shapes on the inner wall of the outer drum 3 to make the material flow outside. The guide flight 31 for lifting, turning and conveying in the drum 3, the height of the guide flight 31 is 150mm, and the inclination guide angle of the guide flight 31 is 15°, so that the material can be lifted, turned and conveyed in the cylinder , the material randomly falls on the crushing blade group 4 of the main shaft 2, and is crushed randomly and non-forced, which can reduce the damage of the crushing blade group 4, improve the life of the crushing blade group 4, and reduce the frequency of replacement; the discharge section C is equipped with a shaftless outlet The material auger 9, the lower left end of the frame 1 is provided with a discharge port 12 corresponding to the position of the shaftless discharge auger 9, and the crushed and discharged material is output into the next process through the discharge port 12, and the shaftless discharge The outer diameter and pitch diameter of the auger 9 are 245X220mm. The shaftless auger 9 is driven by a shaftless auger motor. The power of the shaftless auger motor is 1.5KW, and the speed of the shaftless auger 9 is 20YPM. The scheme of shaftless dragon discharge is convenient for collecting the pulverized slurry and entering the next process; the power mechanism includes a hydraulic station 6 and a hydraulic motor 7, and the hydraulic station 6 is set on the lower front side of the frame 1 and the tugboat mechanism 5 Connected, the hydraulic motor 7 is arranged on the right side of the frame 1, and the hydraulic motor 7 is coaxially connected with the right end of the main shaft 2 to drive the main shaft 2 to rotate. The power of the hydraulic motor 7 is 22KW, and the speed of the main shaft is set to 500YPM.

The working principle is: through the high-speed rotating crushing blade group 4 randomly hitting the material, the purpose of preliminary pulping of the crushed material is achieved.

Process: The material falls into the feed port 11, and at the same time, an appropriate amount of diluent (raw water or reclaimed water) is added to make the solid content of the material reach the requirement of 8% to 14%. The feeding screw 21 on the main shaft 2 of the feeding section A quickly Convey to the crushing section B; the inner wall of the outer drum 3 of the crushing section B is provided with a deflector 31, and the material rolls forward to the discharge section c under the action of the deflector 31 of the outer drum 3, and the material falls to the main shaft 2 during the process When the crushing blade group 4 is used, it is randomly crushed by the toothed crushing blade group 4 rotating at high speed. After the material is randomly crushed many times in the whole process, the material is initially crushed to a particle size ≦ 25mm, and the purpose of preliminary pulping of the crushed material is achieved. The crushed material finally enters the discharge section C, falls into the shaftless discharge auger 9, and is transported from the discharge port 12 to the next processing procedure.

The screw conveying section is installed at the feeding of the equipment, so that the material can enter the crushing chamber smoothly, and there will be no phenomenon of material popping up or splashing out from the feeding port 11; Lifting, overturning and conveying in the cylinder, the material randomly falls on the crushing blade group 4 of the main shaft 2, and is randomly and non-forced crushed, which can reduce the damage of the crushing blade group 4, improve the life of the crushing blade group 4, and reduce the frequency of replacement.
