Description

Technical Field

[0001] The utility model relates to the technical field of rotary kiln equipment, in particular to a rotary kiln reactant adding device. Background Art

[0002] As a calcining equipment, rotary kiln is widely used in mining, metallurgy, cement, lime, chemical industry and waste incineration. The rotary kiln generally starts working by driving the large ring gear through a small gear device. The gears used for transmission have the characteristics of low speed, heavy load, impact load, easy to be polluted by dust and water, and accompanied by high temperature.

[0003] The patent application number CN210058184U discloses a reagent adding device for a chemical reactor. Although in the utility model, the device is provided with two sealing tube mechanisms inside the device body, and the two sealing tube mechanisms operate independently, when the reagent is added, the reagent first enters between the two sealing tube mechanisms, and then enters the inside of the reactor. When the reagent enters the inside of the reactor, the sealing tube mechanism located above the vertical end of the device body will be closed. Such a structural setting can always ensure that the inside of the reactor is isolated from the external environment, prevent the gas inside the reactor from being emitted to the outside, improve the environmental protection of the reactor, and at the same time ensure that the addition of reagents will not be affected by the internal environment of the device. Influenced by, in the utility model, the device is connected by a mounting mechanism at the vertical end of the device body, and the mounting mechanism is mainly composed of two semicircular ring monomers, and the two semicircular ring monomers are fastened by bolts. Such a structural setting makes the installation and disassembly of the device inconvenient, but the device is not suitable for rotary kiln equipment. When adding materials, the existing rotary kiln equipment cannot mix the materials with the reactants, and the commonly used reactants are divided into liquid and powder. When adding, they can generally only be input into the interior of the rotary kiln for reaction, but it is easy for the materials and the reactants to be not fully mixed. Therefore, a utility model is proposed to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the problems that the existing equipment is inconvenient to add reactants and the material reactants cannot be fully mixed with powder or liquid reactants.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a rotary kiln reactant adding device comprises an equipment base, a material box is clamped on the upper surface of the equipment base, a feeding motor is clamped on one side of the material box, a threaded feeding shaft is inserted inside the feeding motor, a feeding pipeline is provided on one side of the equipment base, a reaction powder box is clamped on the upper surface of the feeding pipeline, a driving motor is clamped on one end of the reaction powder box, a powder control shaft is inserted inside the driving motor, a water tank is clamped on one side of the equipment base, a water pump is clamped on the inside of the water tank, a water delivery pipeline is inserted on one side of the water pump, an electric drive tee is sleeved on one end of the water delivery pipeline, a liquid infusion pipeline is inserted on one side of the electric drive tee, an infusion pump is clamped on one end of the liquid infusion pipeline, a reaction liquid box is sleeved on the outer surface of the infusion pump, an injection pipeline is inserted inside the electric drive tee, and an extension motor is inserted on the upper surface of the equipment base.

[0006] Preferably, a control groove is provided on the upper surface of the device base, and an electric drive tee is clamped inside the control groove.

[0007] Preferably, a manual valve is provided on the upper surface of the electric-driven tee, a telescopic space is provided inside the electric-driven tee, and an injection pipe is inserted inside the telescopic space.

[0008] Preferably, an active friction shaft is inserted into the interior of the extension motor, a clamping plate is clamped on the upper surface of the active friction shaft, and a passive friction shaft is inserted into the interior of the clamping plate.

[0009] Preferably, a driver is clamped on the upper surface of the device base.

[0010] Preferably, a movable motor is inserted into the interior of the equipment base, and a movable gear is sleeved on the outer surface of the movable motor.

[0011] Preferably, a slide groove is slidably connected to the lower surface of the equipment base.

[0012] Preferably, a bottom plate is provided on the lower surface of the slide groove, and a tooth row is provided on the upper surface of the bottom plate.

[0013] Preferably, a material funnel is provided on the upper surface of the material box.

[0014] The beneficial effects of the utility model are:

[0015] (1) The utility model adopts structures such as a spray pipe and an extension motor. When liquid needs to be sprayed, the extension motor can rotate the active friction shaft to control the spray pipe to extend outward. During the movement, the passive friction shaft assists the movement of the spray pipe. When conveying materials, the entire equipment needs to move forward to allow the materials to enter the interior of the rotary kiln. When the equipment needs to be repaired and inspected, the moving motor needs to rotate the moving gear to control the equipment base to move forward and backward on the bottom plate. All motors inside the equipment need to be controlled by the driver.

[0016] (2) The utility model uses a feeding motor, a reaction powder box and a reaction liquid box and other structures. When the equipment needs to transport materials to the inside of the rotary kiln, the feeding motor rotates the threaded feeding shaft to make the materials in the material box enter the inside of the rotary kiln along the feeding pipeline for calcination. When the materials are inside the feeding pipeline, the driving motor inside the reaction powder box rotates the powder control shaft to control the reactant powder to enter the feeding pipeline and fully mix with the materials. When the materials are transported to the rotary kiln, the electric drive tee will control the spraying of water or the injection of reactant liquid according to demand. The water tank uses a water pump to let water enter the electric drive tee along the water pipeline and inject it onto the upper surface of the material through the injection pipeline. The reactant in the reaction liquid box is injected into the injection pipeline through the infusion pump along the infusion pipeline and injected, and can also be fully mixed with the materials. When the rotary kiln needs to be inspected or repaired, the moving motor rotates the moving gear to rotate, and the moving gear meshes with the gear row, so that the equipment base moves on the bottom plate, and the slide groove prevents the equipment base from deviating from the track when moving.

[0017] (3) The utility model greatly enhances the use effect of the equipment through the electric drive tee, chute and water pump structures, effectively ensures the full mixing of materials and powder reactants or liquid reactants, and can effectively suppress the dust generated during material injection, thereby reducing the pollution to the environment during the operation of the equipment.

[0018] In summary, the utility model has the advantages of facilitating the mixing of powder reactants, liquid reactants and materials, and effectively reducing dust pollution to the environment during material transportation. BRIEF DESCRIPTION OF THE DRAWINGS

When the materials are in the feeding pipe 5, the driving motor 7 in the reaction powder box 6 rotates the powder control shaft 8 to control the reactant powder to enter the feeding pipe 5 and fully mix with the materials. When the materials are transported to the rotary kiln, the electric drive tee 12 will spray water or spray the reactant liquid according to the demand control. The water tank 9 uses the water pump 10 to let the water enter the electric drive tee 12 along the water pipe 11, and spray it onto the upper surface of the material through the spray pipe 16, which can effectively reduce dust and fully mix the materials.
