Description

Technical Field

[0001] This invention relates to the field of kiln feeding technology, and in particular to a kiln feeding mechanism. Background Technology

[0002] When a glass furnace is in operation, once the internal temperature reaches the required level, raw materials such as crushed glass need to be added. Due to the high furnace temperature, manual feeding is not possible; instead, a conveyor belt or similar mechanism is used to feed the material into the furnace. Because of the rising hot air, to reduce heat loss, the feeding port is usually located at the end or side of the furnace. This requires the conveyor belt or similar feeding mechanism to extend into the feeding port, and the high temperature can affect its service life.

[0003] To address this issue, a glass kiln feeding mechanism, such as the one with patent number CN222250398U, was developed. However, this device has several drawbacks: its conveyor belt is located above the feeding port, and the material enters the opened feeding port in a parabolic trajectory using its initial velocity. This avoids the conveyor belt being directly exposed to heat after the sealing cover is opened. However, it is difficult to ensure that the raw material fed into the conveyor belt is well and completely thrown into the feeding port. During use, raw material often falls outside the feeding port, requiring secondary collection and feeding, which affects processing efficiency. At the same time, when the feeding port is opened and raw material is thrown into it, a large amount of hot air inside the kiln overflows through the feeding port, resulting in waste. Summary of the Invention

[0004] The purpose of this invention is to provide a kiln feeding mechanism.

[0005] The technical problem of this invention is mainly solved by the following technical solution:

[0006] A kiln feeding mechanism includes a feeding pipe located at the top of the kiln body, the top of the feeding pipe being sealed, a guide pipe connected to a feed hopper being inclined upward on one side wall of the feeding pipe, a conveyor belt extending one end to directly above the opening of the feed hopper being provided above the kiln body, a cooling mechanism being provided on the guide pipe, an arched portion protruding outward on one side wall of the feeding pipe below the guide pipe, a flow guide seat being provided on the same side of the feeding pipe below the arched portion, and a sealing seat driven by a hydraulic rod being provided in the opening formed between the flow guide seat and the side wall of the feeding pipe, the flow guide seat and the sealing seat sealing the bottom opening of the feeding pipe;

[0007] The cooling mechanism includes a jacket that is fitted onto the feed tube, and a cooling cavity is formed between the jacket and the feed tube.

[0008] Preferably, the jacket is provided with an inlet pipe and an outlet pipe on its upper and lower sides, respectively.

[0009] Preferably, the top of the flow guide seat is provided with a flow guide slope I, the bottom end of the flow guide slope I is provided on the same side as the sealing seat, and the top end of the flow guide slope I extends into the bottom opening of the arched part.

[0010] Preferably, the top of the sealing seat is provided with a flow guiding slope II, and the bottom end of the flow guiding slope II is located on the same side as the flow guiding seat.

[0011] Preferably, a vertical rod is provided on one side of the top of the sealing seat away from the guide pipe, the output shaft of the hydraulic rod is connected to the top of the vertical rod, a vertical pipe for installing the hydraulic rod is provided on the top sealing end of the feeding pipe, the output shaft of the hydraulic rod passes through the opening of the vertical pipe, a corrugated hose sleeved on the output shaft of the hydraulic rod is fixed on the inner top wall of the vertical pipe, and the bottom end of the corrugated hose is fixedly connected to the top of the vertical rod.

[0012] The beneficial effects of this invention are:

[0013] 1. The conveyor belt feeds the raw material into the feed hopper, and then fills it into the feeding pipe and the arched opening below it through the guide pipe. The hydraulic rod drives the sealing seat to move upward through the vertical rod and move it above the guide pipe. Then the raw material filled into the feeding pipe and the arched opening can flow downward into the kiln through the guide slope I. At this time, the conveyor belt, feed hopper and guide pipe continuously feed the raw material into the feeding pipe and into the kiln, so that the above components are filled with raw material before and during the feeding process. When the sealing seat moves upward and the feeding pipe feeds the kiln, the raw material that is always filled in the above components can prevent the hot air in the kiln from escaping through the opening of the above components, so as to prevent the heat in the kiln from escaping.

[0014] 2. Because the conveyor belt guides the raw materials into the feed hopper and then into the kiln through the guide pipe and feeding pipe, it can effectively ensure that the raw materials flow normally into the kiln and do not fall outside the kiln, thus ensuring the safety of feeding. In addition, the coolant in the cooling chamber cools down the side wall of the guide pipe, preventing the heat in the kiln from being conducted to the feed hopper through the side wall of the feeding pipe and guide pipe. The feed hopper is heated first, and then the conveyor belt is heated, thus ensuring the safety of the conveyor belt. Attached Figure Description

Detailed Implementation

[0018] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0019] A kiln feeding mechanism includes a feeding pipe 2 located at the top of the kiln body 1, the top of the feeding pipe 2 being sealed, and a guide pipe 3 connected to a feed hopper 4 being inclined upward on one side wall of the feeding pipe 2. A conveyor belt 5 extending one end to the top of the opening of the feed hopper 4 is provided above the kiln body 1. A cooling mechanism 6 is provided on the guide pipe 3. The cooling mechanism 6 includes a jacket 61 sleeved on the guide pipe 3, and a cooling chamber 62 is formed between the jacket 61 and the guide pipe 3. An inlet pipe 11 and an outlet pipe 12 are respectively provided on the upper and lower sides of the jacket 61.

[0020] An arched portion 7 protrudes outward from one side wall of the feeding pipe 2 below the guide pipe 3. A flow guide seat 8 is provided inside the feeding pipe 2 below the arched portion 7 and is arranged on the same side. A sealing seat 9 driven by a hydraulic rod 10 is provided in the opening formed between the flow guide seat 8 and the side wall of the feeding pipe 2. The flow guide seat 8 and the sealing seat 9 seal the bottom opening of the feeding pipe 2.

[0021] like Figure 1 , 2 As shown, the top of the flow guide seat 8 is inclined with a flow guide slope I13. The bottom end of the flow guide slope I13 is on the same side as the sealing seat 9, and the top end of the flow guide slope I13 extends into the bottom opening of the arched part 7.

[0022] like Figure 1 , 2 As shown, the top of the sealing seat 9 is provided with a flow guiding slope II14, and the bottom end of the flow guiding slope II14 is located on the same side as the flow guiding seat 8.

[0023] like Figure 1 , 2As shown, a vertical rod 15 is provided on one side of the top of the sealing seat 9, away from the feed tube 3. The output shaft of the hydraulic rod 10 is connected to the top of the vertical rod 15. A vertical tube 16 for installing the hydraulic rod 10 is provided on the top sealing end of the feeding tube 2. The output shaft of the hydraulic rod 10 passes through the opening of the vertical tube 16. A corrugated hose 17, which is sleeved on the output shaft of the hydraulic rod 10, is fixed on the inner top wall of the vertical tube 16. The bottom end of the corrugated hose 17 is fixedly connected to the top of the vertical rod 15. The corrugated hose 17 can effectively prevent the raw material introduced into the feeding tube 2 from contacting the output shaft of the hydraulic rod 10 and causing damage to it, thus protecting it.

[0024] Method of using the present invention: as follows Figure 1 As shown, the conveyor belt 5 feeds the raw material into the feed hopper 4, and then fills it through the guide pipe 3 into the opening of the feeding pipe 2 and the arched part 7 below it. At this time, as... Figure 2 As shown, the hydraulic rod 10 drives the sealing seat 9 to move upward and to the position above the guide pipe 3 via the vertical rod 15. Then, the raw material filled into the feeding pipe 2 and the opening of the arched part 7 can flow downward into the kiln through the guide slope I13. At this time, the conveyor belt 5, the feed hopper 4, and the guide pipe 3 continuously input the raw material into the feeding pipe 2 and into the kiln, so that the above components are filled with raw material before and during the feeding process. When the sealing seat 9 moves upward and the feeding pipe 2 feeds material into the kiln, the raw material that is always filled in the above components can prevent the hot air in the kiln from overflowing through the opening of the above components, thereby preventing the heat from overflowing from the kiln.

[0025] Meanwhile, since the conveyor belt 5 guides the raw materials into the feed hopper 4 and into the kiln through the guide pipe 3 and the feeding pipe 2, it can effectively ensure that the raw materials flow normally into the kiln and do not fall outside the kiln, thus ensuring the safety of feeding. In addition, the cooling liquid in the cooling chamber 62 cools down the side wall of the guide pipe 3, preventing the heat in the kiln from being conducted to the feed hopper 4 through the side wall of the feeding pipe 2 and the guide pipe 3. The conveyor belt 5 is then heated by heating the feed hopper 4, thus ensuring the safety of the conveyor belt 5.

[0026] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
