Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for glass kilns, and specifically relates to a feeding device for electronic glass kilns. Background Technology

[0002] Electronic glass kilns generally use screw feeders for material feeding. The advantages of this method are stable feeding volume and good sealing. Electronic glass batches contain fluxing agents such as boric acid; however, boric acid is prone to agglomeration when heated, increasing feeding resistance. This often causes blockages in the batch material during screw feeder operation, severely affecting the stability of the kiln's production process. Utility Model Content

[0003] The purpose of this invention is to overcome the problem of material blockage in the feeding process of existing electronic glass furnace feeding devices, and to provide a feeding device for electronic glass furnaces.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A feeding device for an electronic glass furnace includes a spiral shaft with spiral blades on it. The spiral blades include a first spiral blade, a second spiral blade, and a third spiral blade with different pitches.

[0006] The pitch L1 of the first helical blade is greater than the pitch L2 of the second helical blade, and the pitch L2 of the second helical blade is greater than the pitch L3 of the third helical blade.

[0007] The proportional relationship between L1, L2 and L3 is defined as follows: L1 = (1.1~1.2) * L2, L2 = (1.1~1.15) * L3.

[0008] The formula for the volume of material conveyed by a spiral blade is: Q = 47β*ψ*ρ*D 2 *L*n,

[0009] Where Q is the volume of material conveyed by the helical blade, β is the inclination coefficient of the helical blade, ψ is the material filling coefficient, ρ is the bulk density of the material, D is the diameter of the helical blade, L is the pitch of the helical blade, and n is the rotational speed of the helical blade.

[0010] Within the same spiral blade, when the size of the spiral blades is the same, the larger the pitch of the spiral blade, the greater the material conveying speed.

[0011] It includes a spiral shaft barrel, wherein the spiral shaft is disposed in the spiral shaft barrel.

[0012] One end of the spiral shaft cylinder is connected to the feeding hopper.

[0013] The other end of the spiral shaft cylinder is connected to the kiln.

[0014] The material in the feeding hopper is transported to the kiln through the spiral blades on the spiral shaft.

[0015] A material pile is formed at the connection between the inside of the kiln and the spiral shaft material cylinder.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This utility model provides a feeding device for an electronic glass kiln, including a spiral shaft, spiral blades, and a spiral shaft cylinder. The spiral blades consist of a first spiral blade, a second spiral blade, and a third spiral blade with different pitches. By varying the pitch of the blades on the spiral shaft, the difference in discharge speed between the front and rear parts of the spiral shaft cylinder is increased, resulting in a lower packing density of material at the front of the cylinder than at the rear. This improves the smoothness of the feeding device and avoids blockage problems within the cylinder. It also ensures a smoother discharge process during material transport within the spiral shaft cylinder, preventing blockages and guaranteeing the stability of the kiln melting process.

[0021] To further understand the present invention, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the embodiments are merely illustrative and not intended to limit the scope of the invention.

[0022] A feeding device for an electronic glass furnace, comprising the following components:

[0023] like Figure 1 As shown, a feeding device for an electronic glass kiln includes a feeding hopper 4, which is connected to a spiral shaft cylinder 3. A spiral shaft 1 is installed inside the spiral shaft cylinder 3, and spiral blades 2 are arranged around the spiral shaft 1. The spiral shaft cylinder 3 is connected to a kiln 5.

[0024] like Figure 2 As shown, preferably, the helical blade 2 includes a first helical blade 21, a second helical blade 22 and a third helical blade 23 with different pitches.

[0025] A feeding device for an electronic glass furnace, the method of use of which is as follows:

[0026] When the screw shaft cylinder 3 conveys the batch material in the feeding hopper 4 to the kiln 5 through the screw shaft 1, a material pile 6 is formed at the connection between the screw shaft cylinder 3 and the kiln 5.

[0027] As the ingredients agglomerate on the surface of the material pile 6 at high temperatures, the forward movement of the batch material within the screw shaft cylinder 3 is further increased. Simultaneously, the batch material at the rear of the screw shaft cylinder 3, driven by the screw blades 2, continuously moves forward, eventually causing blockage within the front of the screw shaft cylinder 3. This increases the friction between the batch material and the screw blades 2, resulting in severe wear on the screw blades 2. The worn-off metal material enters the kiln 5 along with the batch material, creating quality defects.

[0028] Therefore, in this embodiment, the relationship between the pitch L1 of the first helical blade 21, the pitch L2 of the second helical blade 22 and the pitch L3 of the third helical blade 23 is L1 > L2 > L3; the proportional relationship between L1, L2 and L3 is limited to: L1 = (1.1~1.2) * L2, L2 = (1.1~1.15) * L3.

[0029] Furthermore, the formula for the conveyed material volume of the spiral blade 2 is Q=47β*ψ*ρ*D 2 *L*n;

[0030] In the above formula: β is the inclination coefficient of the helical blade; ψ is the material filling coefficient; ρ is the material bulk density; D is the diameter of the helical blade; L is the pitch; and n is the rotational speed.

[0031] In the same spiral blade 2, when the spiral blade 2 has the same size, the larger the pitch, the greater the transmission speed. When the speed at the front is greater than the speed at the rear, the batch material in the rear barrel is always in a relatively sparse state, forming a smoother discharge effect, avoiding blockage of the batch material in the barrel, and ensuring the stability of the kiln melting process.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
