Description

Technical Field

[0001] The utility model relates to the field of sand and gravel drying, in particular to an auxiliary feeding device for a drying drum. Background Art

[0002] As people's living standards improve, the construction industry is also gradually increasing. Dry sand also occupies a dominant position in the construction industry, and the drying drum is also the main equipment for making dry sand.

[0003] When the existing drying drum is working, the relatively wet sand and gravel are usually transported into the drying drum by a belt conveyor or a lifting bucket. Then, the material rotates with the drum, and the wet material moves forward in the drum, and is directly or indirectly heated by the heat carrier, so that the wet material is dried, thereby obtaining dry sand.

[0004] However, some of these wet sands and gravels contain moisture and are easy to stick together. The sticky sands and gravels often block the feed port, causing the sands and gravels to be unable to come down and enter the dryer. However, once the material is cut off, the heating equipment is still heating, and the material in the dryer cylinder will gradually decrease. The heat remains unchanged, which directly causes the temperature in the dryer cylinder to rise sharply, which may cause the equipment cylinder to degenerate, the production volume to decrease, the drying effect is not ideal, and other problems, which will directly increase the cost investment of the factory, and then affect the production efficiency of the enterprise;

[0005] In addition, due to the high temperature of the feed inlet, there are problems of scalding or burns during manual blockage clearing, and the safety of the construction workers cannot be guaranteed. Utility Model Content

[0006] In order to solve the above-mentioned problems, the utility model provides a drying drum auxiliary feeding device.

[0007] The utility model is realized through the following technical scheme: an auxiliary feeding device for a drying drum comprises a drying drum body, a feeding port is arranged on the upper part of one side of the drying drum body, a cavity shell is arranged on the upper part of the feeding port, and the cavity shell is divided into a pre-crushing zone and a material-shifting crushing zone from top to bottom.

[0008] Further optionally, a pre-crushing component is provided in the pre-crushing zone, and a material-shifting component is provided in the material-shifting crushing zone.

[0009] Further optionally, the pre-crushing assembly includes a connecting block arranged in a layered and staggered manner in the pre-crushing zone, a crushing paddle is hingedly fixed in the connecting block, a sliding sleeve is provided at the lower part of the crushing paddle, the sliding sleeve is slidably connected to a limiting groove provided on the sliding rod through a limiting rod, a spring is provided in the limiting groove and is connected and fixed to the limiting rod.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0022] like Figure 1As shown, a drying drum auxiliary feeding device includes a drying drum body 1, a feeding port 3 is arranged on the upper part of one side of the drying drum body 1, a cavity shell 5 is arranged on the upper part of the feeding port 3, and the cavity shell 5 is divided into a pre-crushing area and a material-shifting crushing area from top to bottom.

[0023] like Figure 2 As shown, a pre-crushing assembly is arranged in the pre-crushing zone, and a material-shifting assembly is arranged in the material-shifting crushing zone.

[0024] like Figure 3 , 4 As shown, the pre-crushing assembly includes a connecting block 61 arranged in a layered and staggered manner in the pre-crushing zone, a crushing paddle 6 is hingedly fixed in the connecting block 61, a sliding sleeve 65 is provided at the lower part of the crushing paddle 6, and the sliding sleeve 65 is slidably connected to a limiting groove 66 provided on the sliding rod 62 through a limiting rod 64, and a spring 63 is provided in the limiting groove 66 and is connected and fixed to the limiting rod 64.

[0025] like Figure 2 , 3 As shown, the material discharging assembly includes a conical plate 7 which can disperse and drop the materials in the pre-crushing zone. A central shaft 71 is provided at the lower part of the conical plate 7. A material discharging rotor 9 is provided on the outer side of the central shaft 71. The material discharging rotor 9 is synchronously driven and connected to the output shaft of the driving motor 10 through a connecting sleeve.

[0026] like Figure 3 As shown, the conical plate 7 is fixed to the side wall of the pre-crushing zone of the cavity shell 5 through a connecting rod 8.

[0027] like Figure 3 As shown, a material drop opening 12 is provided at the lower portion of the cavity shell 5 .

[0028] like Figure 2 As shown, the driving motor 10 is supported and fixed on the side wall of the blanking opening 12 by a fixing bracket 11 .

[0029] like Figure 1 As shown, the cavity shell 5 is connected and fixed to the feed port 3 via a connecting plate 13 .

[0030] The implementation principle of the auxiliary feeding device for a drying drum in the embodiment of the present application is as follows:

[0031] Before the drying drum body 1 works, the cavity shell 5 is first fixed to the feed port 2 by bolts, and the external conveying device is placed just above the cavity shell 5, ready to start drying the sand and gravel;

[0032] When the drying drum body 1 is working, the sand and gravel materials are scattered from the upper part of the cavity shell 5 into the pre-crushing area through the conveying device. The sand and gravel entering the pre-crushing area will fall irregularly onto the upper part of several crushing paddles 6. After falling onto the crushing paddles 6, the impact of the sand and gravel will cause the limit rod 64 in the sliding sleeve 65 to slide along the limit groove 66 on the sliding rod 62. Since the spring 63 is arranged in the limit groove, the gravity generated by the falling sand and gravel will compress and deform the spring 63 to generate a rebound force. The generated rebound force will drive the crushing paddle 6 to shake up and down. When some sand and gravel blocks that are bonded together fall onto the crushing paddle 6 that shakes up and down, the crushing paddle 6 that shakes up and down will break them up, thereby completing the sand and gravel pre-crushing.

[0033] The pre-crushed sand and gravel continue to fall, and after falling to the conical plate 7, the pre-crushed sand and gravel are dispersed along the cone surface to the material discharging and crushing area, among which the sand and gravel that are not fully crushed will slide into the gap formed between the material discharging rotor 9 and the cavity shell 5. At the same time, when the sand and gravel fall, the driving motor 10 is started, and the driving motor 10 drives the material discharging rotor 9 to rotate along the central axis 71. The sand and gravel that are not fully crushed will be driven by the material discharging rotor 9 to impact and crush in the space between the side wall of the cavity shell 5, and the crushed sand and gravel will be together with the sand and gravel that are not bonded together when the material discharging rotor 9 rotates. The sand and gravel are thrown out from the angle between them, and the thrown out sand and gravel pass through the lower drop port 12 and enter the inside of the drying drum body 1 from the feed port 2. At the same time, the heating device 4 starts to heat, and the drying drum body 1 starts to rotate and starts to dry. The dried sand and gravel are finally discharged from the discharge port 2 and discharged to the external storage area, completing the entire feeding process. The fully adhered sand and gravel are broken in the whole process, preventing the feed port 3 from being blocked, reducing the investment cost, and improving the output. At the same time, it also speeds up the production efficiency and ensures the safety of life and property of the staff. .
