Description

Technical Field

[0001] This utility model relates to the field of heavy alkali calcination, specifically to a heavy alkali rotary calcination furnace. Background Technology

[0002] The process of calcining heavy alkali is to heat and decompose wet heavy alkali separated by a vacuum filter to produce anhydrous sodium carbonate. The main device used for thermal decomposition is a rotary calcining furnace.

[0003] The existing rotary calcining furnace can be found in the patent application number CN201911095896.5. It has a cylindrical body with a certain inclination. The cylinder is driven to rotate by gears or motors. The material is added from the higher end of the cylinder and discharged from the lower end. Heating the cylinder can dry the material inside. However, in the above-mentioned rotary calcining furnace, the material slides along the axis of the cylinder and quickly leaves the cylinder, resulting in a short residence time of the material inside the cylinder, which easily leads to insufficient drying of the material.

[0004] Therefore, how to extend the residence time of heavy alkali in the calcining furnace is an urgent technical problem to be solved. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a heavy alkali rotary calcining furnace to solve the technical problem that the residence time of heavy alkali in the calcining furnace is too short in the prior art.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a heavy alkali rotary calcining furnace, which includes: A heating assembly includes a furnace body and a heating element, the furnace body having a heating chamber, and the heating end of the heating element being built into the furnace body for raising the temperature within the heating chamber; and The flipping assembly includes a cylinder, a spiral guide plate, and a driving component.

The driving component is connected to the cylinder to drive the cylinder to rotate.

[0007] In some embodiments, the inner wall of the cylinder has a first material distribution plate protruding outward, the first material distribution plate being spiral-shaped and passing through the spiral channel.

[0008] In some embodiments, the flipping assembly further includes a support shaft, the support shaft being internally mounted in the cylinder, the inner edge of the spiral guide plate being connected to the support shaft, and the outer edge of the spiral guide plate being connected to the inner wall of the cylinder.

[0009] In some embodiments, the support shaft has an outwardly protruding second distribution plate, which is spiral-shaped and passes through the spiral channel.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problem of excessively short residence time of heavy alkali in the calcining furnace, this utility model provides a heavy alkali rotary calcining furnace. In the aforementioned heavy alkali rotary calcining furnace, heavy alkali slides down along a spiral channel, thereby extending the residence time of heavy alkali in the heavy alkali rotary calcining furnace.

[0021] It should be noted that the heavy alkali rotary calcining furnace of this utility model is used for heavy alkali drying, etc. For ease of explanation, this utility model is described using the heavy alkali rotary calcining furnace for heavy alkali drying. Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a rotary calcining furnace for heavy alkali in one embodiment of the present invention. The rotary calcining furnace for heavy alkali includes a heating assembly 100 and a turning assembly 200. The heating assembly 100 includes a furnace body 110 and a heating element 120. The furnace body 110 has a heating chamber 111. The heating end of the heating element 120 is built into the furnace body 110 and is used to raise the temperature inside the heating chamber 111. The turning assembly 200 includes a cylinder 210, a spiral guide plate 220 and a driving element 230. The cylinder 210 is inclined and rotatably built into the heating chamber 111 along its axis. The spiral guide plate 220 is built into the cylinder 210, and the spiral guide plate 220 and the inner wall of the cylinder 210 form a spiral channel. The driving element 230 is connected to the cylinder 210 to drive the cylinder 210 to rotate.

[0022] First, the heavy alkali to be dried is placed into the top of the spiral channel. Due to the inclined setting of the cylinder 210, the heavy alkali can slide down along the spiral channel. The heating element 120 raises the temperature inside the heating chamber 111. The heat passes through the cylinder 210 and dries the heavy alkali in the spiral channel. As the cylinder 210 rotates continuously, it can agitate the heavy alkali, ensuring that it is heated evenly. The heavy alkali in the above-mentioned heavy alkali rotary calciner slides down along the spiral channel, thereby prolonging the residence time of the heavy alkali in the rotary calciner and extending the drying time, ensuring that the heavy alkali is fully dried.

[0023] It should be noted that the rotation direction of the cylinder 210 and the spiral direction of the spiral channel both affect the downward speed of the alkali within the spiral channel. If the rotation direction of the cylinder 210 is the same as the spiral direction of the spiral channel, the rotation of the cylinder 210 will increase the downward speed of the alkali. If the rotation direction of the cylinder 210 is opposite to the spiral direction of the spiral channel, the rotation of the cylinder 210 will decrease the downward speed of the alkali. Therefore, if the tilt angle of the cylinder 210 is large, the rotation direction can be opposite to the spiral direction of the spiral channel, thereby slowing down the downward speed of the alkali. If the tilt angle of the cylinder 210 is small, the rotation direction can be the same as the spiral direction of the spiral channel, appropriately increasing the downward speed of the alkali.

[0024] In some embodiments, the inner wall of the cylinder 210 has a first distribution plate 211 protruding outward, which is spiral-shaped and passes through the spiral channel. As the heavy alkali slides in the spiral channel, it will collide with the first distribution plate 211, making the movement trajectory of the heavy alkali more complex and achieving the purpose of fully agitating the heavy alkali.

[0025] In some embodiments, the flipping assembly 200 further includes a support shaft 240, which is cylindrically embedded in the cylinder 210. The inner edge of the spiral guide plate 220 is connected to the support shaft 240, and the outer edge of the spiral guide plate 220 is connected to the inner wall of the cylinder 210. Since the spiral guide plate 220 surrounds and connects to the support shaft 240, the support shaft 240 provides support, thereby preventing deformation of the spiral guide plate 220.

[0026] In some embodiments, the support shaft 240 has an outwardly protruding second distribution plate 241, which is spiral-shaped and passes through a spiral channel. As the heavy alkali slides within the spiral channel, it impacts the second distribution plate 241, making the movement trajectory of the heavy alkali more complex and achieving the purpose of fully agitating the heavy alkali.

[0027] In some embodiments, the heating element 120 includes a heating wire 121, which is laid on the inner wall of the furnace body 110. Applying electricity to the heating wire 121 will cause it to heat up, thereby increasing the temperature inside the heating chamber 111.

[0028] In some embodiments, the inner wall of the furnace body 110 is covered with an insulation layer, which can prevent heat from escaping to the outside of the furnace body 110 and reduce energy loss.

[0029] In some embodiments, a transmission gear 212 is sleeved on the outer periphery of the cylinder 210. The driving component 230 includes a motor 231 and a driving gear 232. The driving gear 232 meshes with the transmission gear 212, and the motor 231 is connected to the driving gear 232 to drive the driving gear 232 to rotate. The motor 231 drives the driving gear 232 to rotate, and since the driving gear 232 and the transmission gear 212 are meshed, the cylinder 210 can be driven to rotate.

[0030] Based on the above embodiments, in some embodiments, there are two transmission gears 212 and two drive gears 232. The two drive gears 232 mesh with the two transmission gears 212 respectively. The drive component 230 also includes a drive shaft 233, which drives the two drive gears 232. A motor 231 is driven by the drive shaft 233 to drive the two drive gears 232 to rotate. The motor 231 drives the drive shaft 233 to rotate, and the rotating drive shaft 233 can drive the two transmission gears 212 to rotate synchronously, thereby driving the two drive gears 232 located at the end of the cylinder 210 to rotate, making the force on the cylinder 210 more even.

[0031] In some embodiments, the flipping assembly 200 further includes a support frame 260 and two bearings 270. The support frame 260 is built into the furnace body 110, and the two bearings 270 are sleeved at both ends of the cylinder 210 and mounted on the support frame 260, so that the cylinder 210 can rotate inside the furnace body 110.

[0032] In some embodiments, the turning assembly 200 further includes a feed hopper 250, which is mounted on the support frame 270, and the discharge end of the feed hopper 250 is connected to the top of the cylinder 210. The operator can feed the alkali to be dried into the feed hopper 250, which guides the alkali into the cylinder 210.

[0033] To better understand this utility model, the following is combined with... Figures 1 to 2 The technical solution of this utility model is described in detail below: First, the heavy alkali to be dried is fed into the feed hopper 250. Guided by the feed hopper 250, the heavy alkali enters the top of the spiral channel. Due to the inclined setting of the cylinder 210, the heavy alkali can slide down along the spiral channel. The heating wire is energized, thereby increasing the temperature inside the heating chamber 111. The heat passes through the cylinder 210 and dries the heavy alkali in the spiral channel. The motor 231 drives the drive gear 232 to rotate. Since the drive gear 232 and the transmission gear 212 mesh, the cylinder 210 can be rotated. As the cylinder 210 rotates continuously, it agitates the heavy alkali, ensuring that it is heated evenly. The heavy alkali in the rotary calciner slides down along the spiral channel, thus extending the residence time of the heavy alkali in the rotary calciner and prolonging the drying time, ensuring that the heavy alkali is fully dried.
