Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fertilizer production equipment, in particular to an ore drying rotary kiln with a uniform feeding device. Background Art
[0002] In the production of fertilizers, especially in the production of compound fertilizers, some raw materials need to be dried to keep them dry so that the quality of the produced compound fertilizers is stable. These raw materials that need to be dried are like ore raw materials, such as phosphate rock, potassium salt, silicon ore, etc. The equipment used for drying is a rotary kiln.
[0003] The existing raw materials are shoveled into the rotary kiln by a loader for drying. Since the loader shovels the ore intermittently, the ore is unevenly distributed in the rotary kiln. The moisture content of the ore coming out of the rotary kiln varies greatly, and secondary drying is required to ensure that the ore is dried and avoid unstable quality of compound fertilizer during the production process.
[0004] Although secondary drying can ensure that moisture is removed from the ore raw materials, the process is repetitive and there is serious waste of energy. Utility Model Content
[0005] In view of this, the purpose of the utility model is to provide an ore drying rotary kiln with a uniform feeding device to address the deficiencies of the prior art. The moisture of the ore raw materials is uniform through stirring, and the ore raw materials are uniformly fed into the ore drying rotary kiln, so that the ore raw materials are uniformly heated in the ore drying rotary kiln to achieve the purpose of one-time drying.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] An ore drying rotary kiln with a uniform feeding device comprises a rotary kiln, wherein the uniform feeding device is arranged at the feeding port of the rotary kiln, wherein the uniform feeding device comprises a feeding hopper, a stirring shaft, a stirring arm, a stirring blade, a reducer, a stirring motor and a discharging auger, wherein the stirring shaft is provided with a stirring arm, and the stirring arm is provided with a stirring blade, the stirring shaft is horizontally placed in the feeding hopper, one end of the stirring shaft extends out of the feeding hopper and is connected to the reducer, the reducer is connected to the stirring motor, a discharging auger is arranged at the bottom of the feeding hopper, and the discharging port of the discharging auger faces the feeding port of the rotary kiln.
[0008] Furthermore, the feed port of the lower hopper is arranged at the upper part of one side of the lower hopper, and the discharge port of the discharge auger is arranged at the lower part of the other side of the lower hopper.
[0009] Furthermore, a chute is provided at the discharge port of the discharging auger, and the chute extends deep into the rotary kiln.
[0010] Furthermore, the stirring arms on the stirring shaft are arranged in a double helix.
[0011] Furthermore, each stirring arm is provided with a stirring blade.
[0012] Furthermore, the blades on the stirring arm on one of the spirals on the stirring shaft are all set at 30°, and half of the stirring blades on the stirring arm on the other spiral are set at 0°, and the other half are set at 30°.
[0013] Furthermore, the discharging auger is provided with a discharging motor at the other end relative to the discharging port.
[0014] Furthermore, there are two discharging augers, which are arranged in parallel and rotate relative to each other.
[0015] The utility model discloses an ore drying rotary kiln with a uniform feeding device. When working, the ore raw materials to be dried are first loaded into the feeding hopper by a forklift or other tools, and then are stirred in the feeding hopper and pushed toward the discharge port. Finally, the ore raw materials are uniformly fed from the feeding hopper by a discharge auger, so that the ore raw materials uniformly enter the ore drying rotary kiln.
[0016] The utility model discloses an ore drying rotary kiln with a uniform feeding device. After the ore raw materials to be dried are loaded into the feeding hopper, since the water contents of various parts of the ore raw materials are different, after entering the feeding hopper, under the action of stirring, the water content of the ore raw materials is approximately uniform. After being uniformly discharged by the discharging auger, the ore raw materials enter the ore drying rotary kiln through the chute. Since the water content of the ore raw materials passing through the uniform feeding device is approximately uniform and the feeding is uniform, after passing through the ore drying rotary kiln, the moisture of the ore raw materials can be dried to meet the production requirements of the fertilizer, and the water content of the dried ore raw materials is uniform.
[0017] The beneficial effects of the utility model are:
[0018] 1. The utility model is an ore drying rotary kiln with a uniform feeding device. The ore raw materials to be dried are stirred after entering the feeding bin, so that the water content of the ore raw materials can be approximately uniform.
[0019] 2. The utility model provides an ore drying rotary kiln with a uniform feeding device. The discharging auger can allow the ore raw materials to enter the ore drying rotary kiln uniformly, thereby achieving uniform feeding.
[0020] 3. The utility model is an ore drying rotary kiln with a uniform feeding device, which is arranged on two discharging augers, which can not only feed evenly, but also further stir the ore raw materials during the feeding process to make the moisture of the ore raw materials more uniform.
