Description

Technical Field

[0001] The utility model belongs to the technical field of kiln charging, and in particular relates to a charging device for kiln baking. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] Before the melting furnace starts production, it needs to be baked. During the baking process, broken glass needs to be continuously added to the furnace. The feeder cannot withstand the high temperature during the baking process and will stick to the material. The material is mainly fed into the furnace manually with a shovel or the like. However, since the temperature of the furnace is above 1000°C, the radiation temperature is very high. This makes the working environment of the workers very harsh and poses a great safety hazard. China's utility model patent CN210595765U discloses a feeding funnel for a melting furnace. The feeding speed is adjusted by setting a threaded rod and a bevel gear structure. However, the feeding funnel still cannot solve the problem of sticking due to high temperature during the feeding process. Utility Model Content

[0004] The utility model aims to provide a feeding device for a kiln, which can solve the problem that the feeding hopper of the existing feeding machine sticks due to high temperature during the feeding process.

[0007] As a further technical solution, the feed trough is a semi-cylindrical trough, and one end provided with a feeding funnel is closed by a semi-circular end plate.

[0008] As a further technical solution, a circular hole is provided at the center of the semicircular end plate, and a push rod passes through the circular hole. One end of the push rod is placed in the feed trough, and the other end is placed outside the feed trough.

[0009] As a further technical solution, a semicircular push plate is provided at one end of the push rod placed in the feed trough, and the semicircular push plate is perpendicular to and fits with the inner wall surface of the feed trough.

[0010] As a further technical solution, a pushing handle is provided at one end of the pushing rod outside the feeding trough.

[0011] As a further technical solution, one end of the push rod placed outside the feed trough is connected to a telescopic cylinder.

[0012] As a further technical solution, the cross-section of the feeding funnel is trapezoidal, the bottom of the feeding funnel is a rectangular outlet, and the width of the feeding funnel is the same as the width of the discharge trough.

[0013] As a further technical solution, the cooling cavity is an arc-shaped closed structure, and a water inlet pipe and a water outlet are provided on the cooling cavity.

[0014] As a further technical solution, the water inlet pipe extends into the interior of the cooling cavity, and the water outlet of the water inlet pipe is close to the end of the feed trough.

[0016] The beneficial effects of the above-mentioned embodiments of the utility model are as follows:

[0017] The feeding device for kiln baking provided by the utility model can ensure that the bottom of the feeding trough is always at a relatively low temperature during the feeding process by arranging a cooling cavity on the feeding trough, thereby avoiding material sticking due to excessive temperature. At the same time, a pushing rod is arranged in the feeding trough to push the material in the feeding trough, and the pushing rod can be directly pushed manually or connected to a telescopic cylinder to push the material. Since the feeding trough can be set to a certain length, even if it is pushed manually, work can be carried out at a place far away from the kiln, which greatly improves the operating environment of the workers and reduces the occurrence of safety accidents.

[0024] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0025] Example 1

[0026] In a typical implementation of the present invention, Figure 1-3 As shown, a feeding device for a kiln baking kiln is provided, comprising a feeding trough 1, a feeding funnel 2 is arranged at one end of the feeding trough 1, and the bottom of the feeding funnel 2 is connected with the feeding trough 1; a cooling cavity 4 is arranged at the bottom of the other end of the feeding trough 1, and circulating cooling water is introduced into the cooling cavity 4; a pushing rod 3 is arranged in the feeding trough 1, and the pushing rod 3 pushes the material out of the feeding trough 1 from the end with the cooling cavity 4 for feeding.

[0027] Specifically, the feed trough 1 is a semi-cylindrical trough, and a semi-circular tube can be directly used as the feed trough. One end provided with the feeding funnel 2 is closed by a semi-circular end plate 5 to prevent the material from leaking out of the feed trough 1. Furthermore, a circular hole is provided at the center of the semi-circular end plate 5, and the push rod 3 passes through the circular hole. One end of the push rod 3 is placed in the feed trough 1, and the other end is placed outside the feed trough 1. A semi-circular push plate 7 is provided at the end of the push rod 3 placed in the feed trough 1. The semi-circular push plate 7 is perpendicular to and fits the inner wall surface of the feed trough 1. The semi-circular push plate 7 is reciprocated to push the material in the feed trough out of the feed trough 1, so as to realize the feeding.

[0028] In this embodiment, the pushing rod 3 is placed at one end outside the feed trough 1 and is provided with a pushing handle 6, and the staff holds the pushing wrench to push the material. Furthermore, in order to realize automatic feeding, the pushing rod 3 is placed at one end outside the feed trough 1 and is connected to a telescopic cylinder, and the pushing rod 3 and the semicircular pushing plate 7 are driven to reciprocate by the telescopic cylinder to complete the feeding.

[0029] In this embodiment, the cross-section of the feeding funnel 2 is trapezoidal, the bottom of the feeding funnel 2 is a rectangular outlet, the width of the feeding funnel is the same as the width of the discharge trough, and the length of the feeding funnel can be set as needed.

[0030] In this embodiment, the cooling cavity 4 is an arc-shaped closed structure, and a water inlet pipe 8 and a water outlet are provided on the cooling cavity. Furthermore, the water inlet pipe 8 extends into the interior of the cooling cavity, and the water outlet of the water inlet pipe is close to the end of the feed trough, and the water outlet is connected to the water outlet pipe 9.

[0031] In this embodiment, the cooling cavity 4 is formed by welding an arc plate at the bottom of the feed trough. In order to facilitate the connection of the water inlet pipe and the water outlet pipe, the water inlet and the water outlet on the cooling cavity are set on the same side. By extending the water inlet pipe into the cooling cavity and close to the end of the feed trough, it can be ensured that after the cooling water enters the cooling cavity, it flows from the end of the feed trough to the water outlet, and then flows out from the water outlet, which can improve the cooling effect. The cooling water cavity can be used to add circulating cooling water to reduce the temperature of the feed trough when it is subjected to radiant heat, and at the same time reduce the sticking of materials caused by excessive temperature.

[0032] When in use, fix the feeding funnel on the installed feeding trough. When feeding, the push rod is at the front of the feeding funnel. After adding appropriate amount of ingredients or broken glass, push the feeding rod manually or with a telescopic cylinder to push the powder into the end of the feeding trough. This feeding device reduces the danger of manual feeding when ordinary feeding machines cannot be used, and improves the working environment of the staff.

[0033] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
