Description

Technical Field

[0001] The utility model relates to the technical field of fly ash processing, in particular to a manually operated solid waste pretreatment device. Background Art

[0002] Fly ash is an ash-like substance produced by coal combustion and is commonly used as an additive to concrete and cement products. It can be synergistically complemented with coal gangue, desulfurization gypsum and carbide slag to prepare belite-sulfoaluminate cement. The use of cement with added fly ash can improve the working performance of concrete, reduce water permeability, and help reduce the temperature rise rate of concrete during concrete production.

[0003] Some existing solid waste pretreatment equipment, when grinding the fly ash poured in, is prone to adhere to the surface of the grinding roller due to the presence of some fly ash in a wet state, affecting the grinding effect. In addition, the grinding roller of this type of pretreatment equipment is usually integrated with the box body. When grinding particles of other sizes are required, other types of pretreatment equipment need to be used, which has relatively low practicality.

[0004] Therefore, those skilled in the art provide a manually operated solid waste pretreatment device to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the existing technology and propose a manually operated solid waste pretreatment equipment. By setting a pretreatment mechanism and a ventilation mechanism, fly ash can be dried to prevent the fly ash from sticking to the surface of the grinding roller when it is ground. By setting a disassembly mechanism, it is possible to select a suitable grinding size according to needs, thereby improving practicality.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a manually operated solid waste pretreatment device, comprising a pretreatment mechanism, two ventilation mechanisms and a disassembly mechanism, the pretreatment mechanism comprising a box, a first motor, two rotating rods, two containing rods, a filter screen and a guide plate, a first belt is provided between the output end of the first motor and one of the front sides of the two rotating rods, a second belt is provided between one side of the outer end surfaces of the two rotating rods, four arc-shaped plates are fixedly provided in the middle position between the inner walls on both sides of the box, four T-shaped blocks are fixedly provided on the upper side between the inner walls on both sides of the box, and baffles are fixedly provided on the lower end surfaces of the four T-shaped blocks;

[0007] The two ventilation mechanisms include two fixed shells and two fixed plates. Three heating wires are fixedly arranged on one side between the inner bottom surface and the inner top surface of the two fixed shells. A fan is fixedly arranged in the middle position between the inner bottom surface and the inner top surface of the two fixed shells.

[0008] The disassembly mechanism includes two U-shaped plates, two multi-stage electric telescopic rods, two connecting plates, a first circular ring, a second circular ring and a second motor. A accommodating cylinder is fixedly arranged between the two connecting plates, a supporting plate is fixedly arranged on the inner bottom surface of the accommodating cylinder, and a grinding roller is rotatably arranged through the middle position of the upper end surface of the supporting plate.

[0009] Through the above technical solution, the first motor drives the two rotating rods to rotate through the first belt and the second belt. The two rotating rods drive the two receiving rods to rotate together during the rotation process. At this time, the fly ash poured into the upper end is guided by the T-shaped block and the baffle, so that the fly ash enters the groove opened in the receiving rod, and before pouring the fly ash, a fan and a heating wire are set to make hot air enter one end of the rotating rod from the conduit at one end of the fixed plate, and then pass through the rotating rod and flow out from the other end. Through the contact between the hot air and the rotating rod, the heat of the rotating rod is transferred to the receiving rod, and the fly ash inside the receiving shell can be dried. By opening the two multi-stage electric telescopic rods, the receiving cylinder is driven downward by the two connecting plates. When it moves to the tail, the second ring can be taken out upward, and the fly ash can be ground by the first ring. Then the multi-stage electric telescopic rod is opened again to raise the receiving cylinder to its original position.

[0010] Furthermore, the first motor is fixedly connected to the box body, and the two rotating rods are rotatably arranged at the front and rear positions between the inner walls of both sides of the box body;

[0011] With the above technical solution, the first motor drives the two rotating rods to rotate, which reduces the use of motors and reduces the use cost.

[0012] Furthermore, the two accommodating rods are respectively fixedly sleeved on the outer end surfaces of the two rotating rods, and the four arc-shaped plates are respectively slidably connected to the two accommodating rods in pairs;

[0013] Through the above technical solution, when the rotating rod rotates, the accommodating rod on the surface is driven to rotate together. When the rotating rod rotates, the accommodating rod is blocked by the arc plate, so that fly ash can only enter from the upper end and exit from the lower end.

[0014] Furthermore, the filter is fixedly arranged on the lower side between the inner walls on both sides of the box, and the guide plate is fixedly arranged on the lower side between the inner walls on both sides of the box;

[0015] Through the above technical solution, the fly ash is screened through the filter, so that the fly ash with small particles can pass through the filter and then slide along the slope of the guide plate into the gap between the second ring and the box.

[0016] Furthermore, the two fixed shells are fixedly arranged at the middle position between the front and rear end surfaces of the box body, and the two fixed plates are fixedly arranged at the other side between the inner bottom surface and the inner top surface of the two fixed shells;

[0017] Through the above technical solution, the hot air inside the fixed shell enters the interior of the rotating rod through the conduit at one end of the fixed plate, then flows out from the other end of the rotating rod, and finally re-enters the interior of the fixed shell through the conduit of the fixed shell, thereby realizing hot air circulation.

[0018] Furthermore, the two U-shaped plates are respectively fixedly arranged on both sides of the lower end surface of the box body, the two multi-stage electric telescopic rods are respectively fixedly arranged in the middle position of the inner bottom surface of the two U-shaped plates, and the two connecting plates are respectively fixedly connected to the output ends of the two multi-stage electric telescopic rods;

[0019] Through the above technical solution, the connecting plate is driven to move by two multi-stage electric telescopic rods, so that the moving distance of the accommodating cylinder can be controlled more accurately.

[0020] Furthermore, the first ring is slidably sleeved on the outer end surface of the grinding roller, the second ring is slidably sleeved on the outer end surface of the first ring, the second motor is fixedly arranged in the middle position of the bottom surface of the accommodating cylinder, and the output end of the second motor is fixedly connected to the grinding roller;

[0021] Through the above technical solution, the grinding roller is driven to rotate by the second motor, and then the convex block on the surface of the grinding roller drives the first ring to rotate, and finally the convex block on the surface of the first ring drives the second ring to rotate.

[0022] The utility model has the following beneficial effects:

[0023] 1. The utility model proposes a manually operated solid waste pretreatment equipment, which drives two rotating rods to rotate through a first motor. During the rotation process, hot air is continuously introduced into the interior of the rotating rod through a fan and a heating wire, so that the heat of the hot air is transferred to the receiving rod. At this time, the fly ash in the receiving rod groove can be dried, and by arranging a T-shaped block and a baffle, the fly ash at the upper end can only slide into the interior of the receiving rod. At this time, when the filter is screening, the fly ash at the upper end has not fallen off, thereby avoiding too much fly ash falling onto the surface of the filter at the same time, thereby improving the screening efficiency.

[0024] 2. The utility model proposes a manually operated solid waste pretreatment equipment, which drives the second ring to rotate by a second motor so that it can grind the fly ash passing through the filter screen, and when it is necessary to change the size of the particles produced by grinding, the multi-stage electric telescopic rod drives the accommodating cylinder to move downward. When it moves to the tail, the second ring is manually taken up, and after the second ring is removed, the multi-stage electric telescopic rod is controlled to raise the accommodating cylinder to its original position. By setting a disassembly mechanism, it can select the appropriate grinding size according to needs, thereby improving practicality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1-6The present invention provides an embodiment of a manually operated solid waste pretreatment device, comprising a pretreatment mechanism 1, two ventilation mechanisms 2 and a disassembly mechanism 3. The pretreatment mechanism 1 comprises a box 101, a first motor 102, two rotating rods 103, two containing rods 106, a filter 110 and a guide plate 111. A first belt 104 is provided between the output end of the first motor 102 and one of the front sides of the two rotating rods 103. A second belt 105 is provided between one side of the outer end surface of the two rotating rods 103. The inner sides of the box 101 are provided with a plurality of belts. Four arc-shaped plates 107 are fixedly provided in the middle position between the walls, four T-shaped blocks 108 are fixedly provided on the upper side between the inner walls on both sides of the box body 101, and baffles 109 are fixedly provided on the lower end faces of the four T-shaped blocks 108. The first motor 102 is fixedly connected to the box body 101, and the two rotating rods 103 are respectively rotatably provided at the front and rear positions between the inner walls on both sides of the box body 101. The two accommodating rods 106 are respectively fixedly sleeved on the outer end faces of the two rotating rods 103, and the four arc-shaped plates 107 are respectively slidably connected to the two accommodating rods 106 in pairs.

[0035] When the slot of the accommodating rod 106 is not at the upper end, the end face of the accommodating rod 106 blocks the fly ash, so that no other fly ash will fall onto the surface of the filter screen 110 during the rotation of the accommodating rod 106.

[0036] The two ventilation mechanisms 2 include two fixed shells 201 and two fixed plates 204. Three heating wires 202 are fixedly arranged on one side between the inner bottom and the inner top of the two fixed shells 201. A fan 203 is fixedly arranged at the middle position between the inner bottom and the inner top of the two fixed shells 201. The opposite end faces of the two fixed shells 201 are respectively fixed at the middle position between the front and rear end faces of the box body 101. The two fixed plates 204 are respectively fixed at the other side between the inner bottom and the inner top of the two fixed shells 201. Before pouring fly ash, the fan 203 and the heating wire 202 are arranged to make the heat The wind enters one end of the rotating rod 103 from the conduit at one end of the fixed plate 204, then passes through the rotating rod 103 and flows out from the other end. Through the contact between the hot air and the rotating rod 103, the heat of the rotating rod 103 is transferred to the containing rod 106, and the fly ash inside the containing shell can be dried. The hot air entering the rotating rod 103 is sucked into the interior of the fixed shell 201 from the other end, realizing the circulation of hot air. Here, the conduit connecting the fixed plate 204 and the fixed shell 201 is set as a hard tube. When the rotating rod 103 rotates, one end of the conduit is located inside the rotating rod 103 and is in a relatively static state.

[0037] The disassembly mechanism 3 includes two U-shaped plates 301, two multi-stage electric telescopic rods 302, two connecting plates 303, a first ring 307, a second ring 308 and a second motor 309. A receiving cylinder 304 is fixedly arranged between the two connecting plates 303, a support plate 305 is fixedly arranged on the bottom surface of the receiving cylinder 304, and a grinding roller 306 is rotatably arranged in the middle position of the upper end surface of the support plate 305. The filter screen 110 is fixedly arranged on the lower side between the inner walls of the two sides of the box body 101, and the guide plate 111 is fixedly arranged on the lower side between the inner walls of the two sides of the box body 101. The U-shaped plates 301 are fixedly arranged on both sides of the lower end surface of the box body 101, and the two multi-stage electric telescopic rods 302 are fixedly arranged in the middle position of the inner bottom surface of the two U-shaped plates 301. The two connecting plates 303 are fixedly connected to the output ends of the two multi-stage electric telescopic rods 302. The first ring 307 is slidably sleeved on the outer end surface of the grinding roller 306, and the second ring 308 is slidably sleeved on the outer end surface of the first ring 307. The second motor 309 is fixedly arranged in the middle position of the inner bottom surface of the accommodating cylinder 304, and the output end of the second motor 309 is fixedly connected to the grinding roller 306.

[0038] The dried fly ash falls onto the surface of the filter 110, and small particles pass through the filter 110 and enter the gap between the second ring 308 and the through hole of the box 101. At this time, the grinding roller 306 is driven to rotate by the second motor 309, and then the convex blocks on the surface of the grinding roller 306 drive the first ring 307 to rotate together, and finally the convex blocks on the surface of the first ring 307 drive the second ring 308 to rotate together. During the rotation of the second ring 308, the fly ash in the gap is ground. When the size of the ground particles needs to be changed, the two multi-stage electric telescopic gates are opened. Rod 302, the multi-stage electric telescopic rod 302 controls the two connecting plates 303 to drive the accommodating cylinder 304 to move downward. When it moves to the tail, the second ring 308 can be taken out upward, and the fly ash can be ground through the first ring 307. Then the multi-stage electric telescopic rod 302 is opened again to raise the accommodating cylinder 304 to its original position. When it moves to the original position, the first ring 307 and the grinding roller 306 are limited by the cylinder at the lower end of the guide plate 111 so that the two cannot move upward. When the box body 101 is moved, the first ring 307 will not move upward.

[0039] Working principle: Before pouring fly ash, turn on the two fans 203 and multiple heating wires 202. At this time, the hot air inside the fixed shell 201 flows into the inside of the two rotating rods 103. Through heat conduction, the temperature inside the receiving rod 106 becomes higher. At this time, fly ash is poured into the upper end of the box body 101, and the first motor 102 and the second motor 309 are turned on. The poured fly ash is guided by the T-shaped block 108 and the baffle 109 and enters the groove of the receiving shell. The first motor 102 drives the receiving rod 106 to rotate. A certain amount of fly ash inside the filter 110 falls onto the surface of the filter 110. At this time, small particles of fly ash pass through the filter 110 and slide into the gap between the second ring 308 and the through hole of the box 101 under the guidance of the guide plate 111. At this time, the second motor 309 drives the second ring 308 to grind the fly ash. When the size of the ground particles needs to be changed, the multi-stage electric telescopic rod 302 is opened to drive the accommodating cylinder 304 to move to the tail, and then the second ring 308 is taken upwards. At this time, the accommodating cylinder 304 is raised to its original position.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
