[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] This lime double-chamber vertical kiln mobile charging device has never appeared before. We designed it for the first time and used it in the mobile rotating charging equipment on the top of the newly designed lime vertical kiln. Its beneficial effects are as follows:

[0017] 1) The mobile feeding device of the lime double-chamber vertical kiln adopts a rotating hopper driven by a variable frequency motor reducer. It can set the hopper rotation speed within the range of 8 to 16 r / min according to the amount of material conveyed by the upstream process equipment to adjust the operating speed to meet the needs of process production, making the process production line more flexible and making the materials in the rotating hopper and the kiln chamber more evenly dispersed, which is beneficial to improving the calcination quality of the materials in the kiln chamber.

[0018] 2) The design of the mobile rotary hopper overall device for horizontally moving material receiving and feeding (including the overall mobile vehicle, mobile vehicle guide rails and combined gantry, rotary hopper support ring beam and 12-frame hollow ring beam supported by the rotary hopper drive) is driven by a variable frequency motor reducer to control the moving speed within the range of 0.2-0.8m / s, which can meet the feeding quantity requirements of the mobile feeding device for process production. The mobile material receiving and feeding device replaces the reversible belt conveyor and the rotary feeding hopper, rotary hopper lifting device, kiln chamber closing gate and other equipment of each kiln chamber, simplifies the feeding process of the top of the vertical kiln chamber, solves the problem of poor connection between several equipments, reduces the total height of the kiln body, reduces the overall engineering cost of the vertical kiln, and provides a new, timely and effective mobile feeding solution.

[0019] 3) A hopper rotating support structure with 3 to 5 (preferably 3) centripetal support wheels evenly distributed within a 360° circumference is adopted. This method is simple and reliable. The centripetal method can ensure that the rotating hopper runs on a predetermined circular track. The photoelectric detection method can sense the rotation speed of the support wheel and the rotating hopper. This method is stable and reliable; a hopper top cover with a 12-side split structure and an electronic level measuring device in the hopper are used to detect the material level in the rotating hopper, that is, high material level and low material level send feedback signals to the main control room to ensure that the feeding process is safe and controllable, and avoid over-limit blockage or insufficient feeding of materials in the hopper; the sealed material bell at the bottom of the feeding hopper is lifted and lowered by a motor reducer, and the lifting stroke can be pre-set and adjusted. It can set different discharge heights and angles according to different material levels in the kiln chamber, and accurately adjust the annular top surface of the material in the kiln to ensure uniform distribution, so that the limestone material in the kiln is evenly heated, thereby improving product quality.

[0020] 4) The device is equipped with a charging seal and hot flue gas dust recovery at the top of the hopper, which reduces smoke and CO2 emissions. A removable, 15-20mm thick (data selected after considering noise reduction and construction difficulty) silent rubber lining is installed on the side wall of the rotating hopper and the sealing surface of the bell, which not only improves the sealing effect, but also greatly reduces the noise when loading and feeding into the kiln chamber, greatly improves the operating environment of the kiln top, and meets the environmental protection requirements for vertical kilns.

[0021] 5) The mobile charging device of the double-chamber vertical kiln is advanced, reasonable, practical and reliable. The system cost is low, the structure is reliable, and it is easy to promote and apply. It provides a new, timely and effective mobile charging solution for the top of the double-chamber kiln, meeting the requirements of the new lime vertical kiln process.

[0022] 6) The device is equipped with sensing detections such as position, weight, and material level to ensure smooth connection of the various components of the device. The use of many sensing detection devices is very important for ensuring the operation of the mobile rotary feeding device. They ensure the safety of the surrounding equipment and personnel during the entire rotary feeding and equipment movement, improve the working efficiency of the double-chamber vertical kiln top feeding, and enable the kiln chamber production to operate continuously safely, stably, and efficiently.
