Description

Technical Field

[0001] This utility model relates to the technical field of stone and coal collection devices, and in particular to a mobile stone and coal collection device. Background Technology

[0002] Coal dust is a typical industrial waste generated during the pulverized coal preparation process in coal-fired power plants. It consists of a mixture of uncrushed pyrite, gangue, and coal particles. It is mainly produced during the operation of medium-speed coal mills and ball mills, and is characterized by high sulfur content, low calorific value, and high ash content. Since its commissioning, the original design for discharging coal dust involved placing it in handcarts through the slide doors of the coal dust storage chamber, with unloading and transfer done manually.

[0003] Currently, the open-type slag discharge design of the coal mill in the pulverizing system causes significant dust pollution and harmful gas emissions from the mill and boiler, reducing the operational reliability of the equipment in this area and increasing maintenance costs. During high-load operation of the unit, the entire stone and coal slag discharge process is limited by the loading capacity of the handcart, requiring frequent transfer and operation of the gate valve for slag discharge. This not only results in a high failure rate of the stone and coal slag discharge gate but also leads to high labor costs. Furthermore, it poses safety hazards to unloading workers during the operation. Therefore, it is necessary to provide a mobile stone and coal collection device to solve the above-mentioned technical problems. Utility Model Content

[0004] The technical problem this invention aims to solve is that the current open-type slag discharge system causes significant dust pollution and harmful gas emissions from coal mills and boilers, reducing the operational reliability of equipment in the area and increasing maintenance costs. To address these shortcomings, this invention provides a mobile stone coal collection device, comprising a housing and a slag discharge pipe. Symmetrical fork slots are provided on one side of the housing, and a push-pull handle is fixedly installed on the top of the housing. Installation slots are symmetrically provided on the front and rear surfaces of the housing, and wheels are rotatably connected to the inner side of each installation slot. A feed hopper is located on the top of the housing. This invention transforms the original open-type stone coal storage chamber and manual handcart into an integrated sealed collection device, increasing slag capacity and reducing the frequency of slag discharge and transfer. The collection device is equipped with push-pull handles on top and wheels and forklift slots on the bottom. After the stone and coal waste is collected, it is transported to the transfer channel between the two units. The transfer work is completed by forklifts, which can improve human-machine efficiency. The sealed slag discharge design reduces the equipment failure rate and improves human-machine efficiency. At the same time, it can improve and solve the long-standing problem of safety, health and environmental protection in the pulverizing system area.

[0023] Example 1:

[0024] like Figure 1-5 As shown, a mobile stone and coal collection device of this utility model includes a box body 12 and a slag discharge pipe 8. A fork groove 1 is symmetrically opened on one side of the box body 12, and a push-pull handle 2 is fixedly installed on the top of the box body 12. The front and rear surfaces of the box body 12 are symmetrically opened with mounting grooves 7. A wheel 13 is rotatably connected to the inner side of each mounting groove 7. A feed hopper 4 is provided on the top of the box body 12, and a first sealing flange 5 is provided on the outer side of the feed hopper 4. A second sealing flange 10 that contacts the first sealing flange 5 is sleeved on the lower end of the slag discharge pipe 8, and a fixed seat 18 is fixedly installed on the top of the slag discharge pipe 8. A movable rod 17 is rotatably connected to the front surface of the fixed seat 18, and a fixed block 15 is fixedly installed on the front surface of the movable rod 17. A hand-adjusting bolt 14 is screwed into the inside of the fixed block 15, and an abutment block 16 that contacts the first sealing flange 5 is rotatably connected to one end of the hand-adjusting bolt 14.

[0025] During implementation, the original open-type stone and coal storage room and manual handcart were transformed into an integrated sealed collection device, increasing the waste slag capacity and reducing the frequency of slag transfer. A push-pull handle 2 is designed above the collection device's housing 12, and wheels 13 and forklift slots 1 are arranged below. After collection, the stone and coal waste slag is transported to the transfer channel between the two units, where a forklift completes the transfer work, improving human-machine efficiency. The sealed slag discharge design reduces equipment failure rate, improves human-machine efficiency, and simultaneously addresses and resolves long-standing safety, health, and environmental (SHE) issues in the pulverizing system area. The feed hopper 4 and the slag discharge pipe 8 are connected by a first sealing flange 5 and a second sealing flange 10, and are used in conjunction with a hand-adjusting bolt 14, a fixing block 15, an abutment block 16, a movable rod 17, and a fixing seat 18. The abutment block 16 abuts against the first sealing flange 5, facilitating a tight fit between the first sealing flange 5 and the second sealing flange 10, and simplifying assembly and fixation.

[0026] like Figure 1As shown, a feed hopper 4 is fixedly connected to the upper end of the slag discharge pipe 8, and a shut-off valve 6 is installed on the slag discharge pipe 8. The material discharge is controlled by opening and closing the shut-off valve 6.

[0027] like Figure 1-2 As shown, a pressure relief mechanism 3 is provided on the top of the box 12. The pressure relief mechanism 3 is located on the right side of the push-pull armrest 2. The movable rod 17 has an L-shaped structure, and the movable rod 17 is rotatably connected to the fixed seat 18 through a rotating shaft.

[0028] Example 2:

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: a fixed bracket 11 is fixedly installed at the bottom of the slag discharge pipe 8, the fixed bracket 11 is located between the shut-off valve 6 and the second sealing flange 10, a support plate 21 is fixedly installed on one side of the fixed bracket 11, a U-shaped block 20 is provided on the top of the support plate 21, two buffer springs 22 are fixedly connected between the U-shaped block 20 and the fixed bracket 11, a protrusion 19 that is inserted into the U-shaped block 20 is fixedly installed on one side of the box body 12, a guide slide rail 23 is provided on the upper surface of the support plate 21, and a guide slider 24 that is slidably connected to the guide slide rail 23 is fixedly installed on the lower surface of the U-shaped block 20.

[0030] In practice, a protrusion 19, a U-shaped block 20, and a buffer spring 22 are provided between the housing 12 and the fixed bracket 11. The U-shaped block 20 and the support plate 21 are movably connected by a guide slider 24 and a guide rail 23. When the housing 12 is in place, the protrusion 19 and the U-shaped block 20 come into contact. At this time, the elastic deformation capability of the buffer spring 22 can be used to avoid rigid collisions and improve the protection capability.

[0031] This technical solution also includes a pre-set track at the work site to match the wheels 13. Before use, the housing 12 of this device is first moved to the fixed support 11 using the push-pull handle 2 and wheels 13. At this time, the first sealing flange 5 and the second sealing flange 10 are in contact. When the protrusion 19 and the U-shaped block 20 are in contact, the buffer spring 22 undergoes elastic deformation, which plays a role in buffering and protection. Then, the movable rod 17 is rotated so that the abutment block 16 is located on the left side of the first sealing flange 5. Finally, the hand-adjusting bolt 14 is rotated so that the abutment block 16, which is rotatably connected to it, is in contact with the first sealing flange 5, and the first sealing flange 5 and the second sealing flange 10 are tightly contacted and fixed. During use, the shut-off valve 6 is opened so that the stones and coal are collected inside the housing 12 through the slag discharge hopper 9, slag discharge pipe 8 and feed hopper 4.
