Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically to a non-powered, air-leak-proof clinker feeding device. Background Technology

[0002] Cement clinker is a semi-finished product obtained by mixing limestone, clay, and iron-based raw materials in appropriate proportions to form raw meal, burning it until partially or completely melted, and then cooling it. After processing, cement clinker is usually stored in silos and discharged as needed. After discharge, it is typically transported by a chain bucket conveyor.

[0003] After the cement clinker is fed, it is collected by the hoppers on the chain bucket conveyor. During the feeding process, because there is a certain gap between the chain buckets on the chain bucket conveyor, the cement clinker needs to be opened and closed frequently as the chain bucket conveyor is running, which is too troublesome. If the feeding hoppers are not repeatedly opened and closed, the clinker will fall between the chain buckets, resulting in clinker waste.

[0004] A non-powered, air-leak-proof clinker feeding device was proposed to address the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a non-powered, air-leak-proof clinker feeding device to solve the problem mentioned in the background art. Currently, after cement clinker is fed, it is collected by hoppers on a chain conveyor frame. During the feeding process, due to the certain interval between the chain hoppers on the chain conveyor, the cement clinker needs to be frequently opened and closed as the chain conveyor operates, which is too troublesome. If the feeding hoppers are not repeatedly opened and closed, the clinker will continuously fall between the chain hoppers, causing clinker waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a non-powered, air-leak-proof clinker feeding device, including a feeding hopper;

[0007] Also includes:

[0008] The hopper is equipped with feeding components both inside and outside;

[0009] The feeding assembly includes a baffle disposed inside the lower part of the feeding hopper, and rotating shafts are symmetrically installed on the upper sides of both sides of the baffle, and the rotating shafts are rotatably connected to the feeding hopper. A positioning strip is fixedly installed on the lower side of one side of the feeding hopper, and the baffle is in contact with the positioning strip.

[0010] In this configuration, a first sprocket is fixedly installed at one end of each of the two rotating shafts that are far apart from each other. A torsion spring is sleeved on the outside of the rotating shaft on one side of the first sprocket. The two ends of the torsion spring are fixedly connected to the hopper and the first sprocket, respectively. The torsion spring is in a stretched state. A rotating rod is rotatably connected to one side of the hopper. Both ends of the rotating rod pass through the hopper and are fixedly installed with a second sprocket. The second sprocket is rotatably connected to the first sprocket via a chain.

[0011] Preferably, a fixing frame is fixedly installed on one side of each of the two second sprockets on the outside of the rotating rod, and a fixing sleeve is fixedly installed on the lower side of one side of the fixing frame. An adjusting frame is slidably connected inside the fixing sleeve, and a roller is rotatably connected between the two adjusting frames.

[0012] Preferably, a positioning frame is fixedly installed on one side of each of the two fixed frames on the outside of the hopper, and a support frame is rotatably connected to one side of the positioning frame. A movable rod is slidably connected inside the support frame, and a telescopic spring is sleeved on the outer side of the movable rod. One end of the telescopic spring is fixedly connected to the support frame, and a fixing block is fixedly installed on the other end of the telescopic spring. The fixing block is fixedly connected to the movable rod.

[0013] Preferably, a connecting frame is fixedly installed on one side of the fixing block, and one side of the connecting frame is rotatably connected to the fixing frame.

[0014] Preferably, a U-shaped frame is fixedly installed on the side of the fixed sleeve away from the hopper, and a movable rod is symmetrically slidably connected inside the U-shaped frame. A movable plate is fixedly installed at one end of the two movable rods, and a positioning rod is symmetrically installed on the side of the movable plate close to the fixed sleeve. The positioning rod is inserted into the fixed sleeve, and a number of positioning holes are opened through one side of the adjusting frame. The positioning rod is inserted into the positioning hole.

[0015] Preferably, a return spring is sleeved on the outer side of each of the two moving rods, and a connecting plate is fixedly installed at the other end of the two moving rods, and the two ends of the return spring are fixedly connected to the connecting plate and the U-shaped frame respectively.

[0016] Preferably, the connecting plate has a knurled screw threaded to its internal center, and a threaded hole is provided through one side of the U-shaped frame, with the knurled screw threaded to the threaded hole.

[0017] Compared with the prior art, the beneficial effects of this utility model are: this non-powered, air-leak-proof clinker feeding device allows for automatic feeding of cement clinker based on the movement of the chain bucket, eliminating the need for frequent opening and closing of the feeding hopper, and preventing clinker from falling into the gaps between the chain buckets, thus avoiding waste and improving practicality. The specific details are as follows:

[0018] 1. When discharging concrete clinker, a chain bucket conveyor is installed below the hopper. The chain bucket conveyor drives the chain buckets to move. After moving, one side of the chain bucket can abut against the roller shaft. The movement of the chain bucket can then push the adjusting frame to rotate. This rotation of the fixed frame is driven by the fixed sleeve. After the fixed frame rotates, the movable rod can slide on the support frame through the connecting frame, which can drive the tension spring. The fixed frame can drive the rotating rod to rotate in the hopper. After the rotating rod rotates, the connection between the first sprocket and the second sprocket can drive the rotating shaft to rotate, which can stretch the torsion spring and thus drive the baffle to rotate. The baffle can rotate downwards, allowing the clinker inside the hopper to leak out and enter the chain hopper. During the movement of the chain hopper, the roller can rotate at the top of the chain hopper. After the chain hopper moves, the roller moves away from the chain hopper. At this time, under the action of the torsion spring and the extension spring, the rotating rod rotates to reset, causing the baffle to reset. After the baffle resets, it fits with the positioning strip to prevent air and ash leakage from the hopper. This allows for automatic feeding of cement clinker based on the movement of the chain hopper, eliminating the need for frequent opening and closing of the hopper and preventing clinker from falling into the gaps between the chain hoppers, thus avoiding waste and improving practicality.

[0019] 2. During use, the knurled screws can be rotated according to the height of the chain bucket to remove the limiting position of the connecting plate. Then, the connecting plate can be pulled to move the moving rod, which in turn moves the positioning rod, causing it to disengage from the positioning hole. This removes the limiting position of the adjusting frame, allowing the height of the roller shaft to be adjusted. After adjustment, the connecting plate can be released, and the return spring will reset, causing the positioning rod to engage with another positioning hole. Then, one end of the knurled screw can be screwed into the threaded hole to position the connecting plate, facilitating the adjustment of the height of the adjusting frame. This allows for easy adjustment of the roller shaft height based on the height of the chain bucket, enabling the movement of the chain bucket to control the opening and closing of the baffle.

A positioning bracket 212 is fixedly installed on the upper side of one side of each of the two fixing brackets 208 on the outside of the hopper 1. A support bracket 213 is rotatably connected to one side of the positioning bracket 212.

One end of the telescopic spring 215 is fixedly connected to the support frame 213, and a fixing block 216 is fixedly installed on the other end of the telescopic spring 215. The fixing block 216 is fixedly connected to the movable rod 214, which can support the rotation of the fixing frame 208 and facilitate the subsequent reset of the fixing frame 208. A connecting frame 217 is fixedly installed on one side of the fixing block 216, and one side of the connecting frame 217 is rotatably connected to the fixing frame 208, so that the fixing frame 208... Rotation can move the movable rod 214. A U-shaped frame 218 is fixedly installed on the side of the fixed sleeve 209 away from the hopper 1.

A threaded hole is opened through one side of the U-shaped frame 218, and the knurled screw 225 is threaded into the threaded hole, which can position the connecting plate 223.

[0031] Working principle: Before using this non-powered, air-leak-proof clinker feeding device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 7As shown, when discharging concrete clinker, a chain bucket conveyor is installed below the discharge hopper 1. The chain bucket conveyor drives the chain bucket to move. After moving, one side of the chain bucket can abut against the roller shaft 211. The movement of the chain bucket can push the adjusting frame 210 to rotate. The fixing sleeve 209 pushes the fixing frame 208 to rotate. After the fixing frame 208 rotates, the connecting frame 217 pulls the movable rod 214 to slide on the support frame 213, which can drive the tension spring 215. The fixing frame 208 can drive the rotating rod 206 to rotate in the discharge hopper 1. After the rotating rod 206 rotates, the connection between the first sprocket 207 and the second sprocket 204 can drive the rotating shaft 202 to rotate, which can stretch the torsion spring 205, thus... The baffle 201 can be rotated downwards, allowing the clinker inside the hopper 1 to leak out and enter the chain bucket. During the movement of the chain bucket, the roller 211 can rotate at the top of the chain bucket. After the chain bucket moves, the roller 211 leaves the chain bucket. At this time, under the action of the torsion spring 205 and the extension spring 215, the rotating rod 206 rotates and resets, causing the baffle 201 to reset. After the baffle 201 resets, it fits with the positioning strip 203 to prevent air and ash leakage from the hopper 1. This allows for automatic feeding of cement clinker based on the movement of the chain bucket, eliminating the need for frequent opening and closing of the hopper 1. It also prevents clinker from falling into the gaps between the chain buckets, avoiding waste and improving practicality.

[0032] During use, the knurled screw 225 can be rotated according to the height of the chain bucket, causing the connecting plate 223 to lose its limit. Then, the connecting plate 223 can be pulled to move the moving rod 219, which in turn moves the positioning rod 221, causing the positioning rod 221 to disengage from the positioning hole 222. This causes the adjusting frame 210 to lose its limit, and the height of the roller shaft 211 can be adjusted. After adjustment, the connecting plate 223 is released, and the return spring 224 is reset, causing the positioning rod 221 to engage with the other positioning hole 222. Then, one end of the knurled screw 225 is screwed into the threaded hole to position the connecting plate 223, which facilitates the adjustment of the height of the adjusting frame 210. This, in turn, facilitates the adjustment of the height of the roller shaft 211 according to the height of the chain bucket, so that the movement of the chain bucket can control the opening and closing of the baffle 201.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
