Description

Technical Field

[0001] The utility model belongs to the technical field of conveying equipment, and particularly relates to a wet salt auger hoist. Background Art

[0002] Since salt is a small particle material, an auger elevator suitable for small particle materials is often used when it is lifted and transported. The spiral auger in the auger elevator spirally propels the material in the auger barrel to achieve the function of transmitting and lifting the material (such as an adjustable auger elevator with publication number CN216334790U).

[0003] In vacuum salt-making enterprises, the wet salt after dehydration by the centrifuge contains about 3% moisture. In the process of conveying wet salt by the auger elevator, some of the wet salt containing moisture will adhere to the spiral blades of the auger elevator. After long-term operation, it will gradually accumulate on the spiral blades of the auger elevator. The more it sticks, the more it will cause the following three main problems:

[0004] Problem 1: The coated salt layer will reduce the conveying channel inside the auger and reduce the conveying efficiency. At the same time, the coated salt layer will increase the rotation burden of the auger, further reducing the conveying and lifting efficiency of the auger hoist;

[0005] Problem 2: The salt layer wrapped around the spiral blades on the auger, accelerating the corrosion of the spiral blades by wet salt;

[0006] Question 3: On the other hand, due to the uneven thickness of the attachments, the centrifugal force on the auger is unbalanced when the auger is running, which will cause the auger to shake significantly. The shaking will bring additional load loss to the power source of the auger, resulting in useless energy consumption.

[0007] In view of the above three main problems, it is necessary to make targeted improvements to the auger elevator used for salt lifting. Utility Model Content

[0008] The purpose of the utility model is to provide a wet salt auger hoist to solve the three main technical problems mentioned in the above background technology.

[0010] A wet salt auger elevator, comprising: a main support and an inclined channel; the inclined channel is a long and inclined closed channel fixed on the main support, and an inclined auger is rotatably fitted in the inclined channel through an end bearing. The main body of the inclined auger is a rotatable first auger shaft, and a spiral first spiral blade is provided on the first auger shaft. A pipe is connected below the top of the inclined channel to form a discharge port. A feeding hopper is connected above the bottom of the inclined channel. The feeding hopper is inclined downward, and is communicated with the inclined channel below and the end of a drying cylinder with a horizontal cylindrical structure above. The drying cylinder is composed of a concentric rotating cylinder and a fixed cylinder. The rotating cylinder and the fixed cylinder are rotatably fitted through a sealed bearing. The fixed cylinder is fixed on the main support through a sub-support with a frame structure. A feeding hopper is fixedly connected above the fixed cylinder. The rotating cylinder is rotatably fitted with the sub-support through a rotating support mechanism. The outer end of the fixed cylinder is closed, and a horizontal auger is concentrically fixed inside the drying cylinder. The main body of the horizontal auger is a tubular second auger shaft, and the end of the second auger shaft close to the feeding hopper is closed; a spiral second spiral blade is provided on the second auger shaft, and air injection holes communicating with the inside of the drying cylinder are provided on the second auger shaft inside the drying cylinder.

[0011] Further: In order to slow down the fixing pressure of the fixed cylinder and prevent the fixed cylinder from being deformed under the lever action, one end of the second auger shaft close to the fixed cylinder is extended, and an extender of a bracket structure wraps the extended part of the second auger shaft and fixes it on the sub-support.

[0012] Further: In order to facilitate the connection of the heat source pipe to the horizontal auger, a gas connection head with a flange structure is provided at one end of the second auger shaft close to the extender, and a sealing rubber ring is provided on the flange end face of the gas connection head.

[0013] Further: In order to improve the rotation smoothness of the rotating cylinder, the rotating support mechanism includes: a ring rail, a rotating bracket, a bearing seat, a rotating rod, and a support wheel. The ring rail is an annular track structure, and the number of the ring rails is at least two groups. The ring rails are externally embedded and fixed on the outer periphery of the rotating cylinder. Each group of ring rails is supported by two groups of support wheels. Each group of support wheels is rotatably fitted on two groups of bearing seats through a rotating rod, and each group of bearing seats is fixed on the sub-support by a rotating bracket.

[0014] Further: In order to enable the rotating cylinder to have the ability of active rotation, a chain ring is externally embedded and fixed on the outer periphery of the rotating cylinder. The chain ring is meshed with a driving sprocket through a chain, and the driving sprocket is externally connected with a rotating power.

[0015] Furthermore: in order to make the rotation of the driving sprocket and the inclined auger only require a set of motors with lower equipment cost, a power motor is fixed to the top of the inclined channel through a motor bracket, and a pulley is concentrically fixed to the outside of the inclined channel at the top of the first auger shaft, and the pulley and the output shaft of the power motor are matched through a belt; the bottom of the first auger shaft protrudes to the outside of the inclined channel and is connected to the transmission shaft of a universal coupling and a rod-shaped structure, and a number of horizontal bearing seats are fixed on the main bracket, and the horizontal bearing seats are embedded in the outer periphery of the transmission shaft through bearings to maintain rotational cooperation with the transmission shaft, and the driving sprocket is concentrically fixed to the transmission shaft with a key.

[0016] Furthermore: in order to prevent the auxiliary bracket from interfering with the transmission of the chain between the driving sprocket and the chain ring, the auxiliary bracket is provided with a chain channel for the chain to pass and move between the driving sprocket and the chain ring.

[0017] Furthermore, because the wet salt will be concentrated at the bottom of the drying drum under the action of gravity, the jet holes serving as the drying heat source are arranged on the second auger shaft with the holes facing downward.

[0018] Furthermore: in order to enable the humidity salt fed from the feed hopper to directly enter the rotating drum, a guide plate with an inclined plate structure is fixed below the feed hopper, and the lower part of the guide plate extends into the rotating drum.

[0019] In summary, the utility model has the following beneficial effects:

[0020] ① Through the establishment of a drying cylinder, a high-temperature airflow pipeline is connected to the air connection head to dry the high-temperature airflow. The high-temperature airflow enters the second auger shaft of the tubular structure from the air connection head and is ejected from the air jet hole on the second auger shaft. The high-temperature airflow ejected from the air jet hole will dry the wet salt in the rotating cylinder. That is to say, the wet salt will be dried by the high-temperature airflow in the process of being transported from the feed hopper side to the feed hopper. When the length of the rotating cylinder and the matching horizontal auger is long enough, the wet salt can be dried to the required dryness, with less stickiness and adhesion of the salt material; therefore, when the inclined auger lifts and transports dry salt, compared with lifting and transporting wet salt, the adhesion of wet salt on the inclined auger can be greatly reduced, and the wet salt can be prevented from excessively adhering to the inclined auger which is inconvenient to maintain, affecting the conveying efficiency of the inclined auger. At the same time, in the subsequent processing of wet salt, part of the drying process can also be reduced, simplifying the post-processing process of the salt material.

[0021] ② Due to the reduction of salt attached to the inclined auger, the salt layer is avoided from reducing the conveying channel inside the auger and the rotation burden of the auger is reduced, maintaining the conveying and lifting efficiency of the auger elevator; at the same time, it also reduces the corrosion of the spiral blades by wet salt on the inclined auger and reduces the useless consumption of energy.

Detailed implementation mode

[0030] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0031] Embodiment:

[0032] Please refer to Figures 1 - 7 , the present utility model provides the technical solution:

[0033] A wet salt auger elevator, comprising: a main bracket 1 and an inclined channel 2; the inclined channel 2 is a long and inclined closed channel fixed on the main bracket 1, and an inclined auger 3 is rotatably fitted in the inclined channel 2 through an end bearing 33. The main body of the inclined auger 3 is a rotatable first auger shaft 31, and a spiral first spiral blade 32 is provided on the first auger shaft 31. A pipeline is conductively connected below the top of the inclined channel 2 to form a discharge port 10. Above the bottom of the inclined channel 2, a feeding hopper 17 is connected. The feeding hopper 17 is arranged obliquely downward, and is conductively connected to the inclined channel 2 below and to the end of a drying cylinder 5 with a horizontal cylindrical structure above. The drying cylinder 5 is composed of a concentric rotating cylinder 51 and a fixed cylinder 52. The rotating cylinder 51 and the fixed cylinder 52 are rotatably fitted through a sealed bearing. Among them, the fixed cylinder 52 is fixed on the main bracket 1 through a sub-bracket 14 with a frame structure. Above the fixed cylinder 52, a feeding hopper 6 is conductively fixed. The rotating cylinder 51 is rotatably fitted with the sub-bracket 14 through a rotating support mechanism 8. The outer end of the fixed cylinder 52 is closed, and a horizontal auger 7 is concentrically fixed inside the drying cylinder 5. The main body of the horizontal auger 7 is a tubular second auger shaft 71, and the end of the second auger shaft 71 close to the feeding hopper 17 is closed; a spiral second spiral blade 72 is provided on the second auger shaft 71, and air spray holes 74 communicating with the inside of the drying cylinder 5 are provided on the second auger shaft 71 inside the drying cylinder 5.

[0034] In order to slow down the fixing pressure of the fixed cylinder 52 and prevent the fixed cylinder 52 from being deformed under pressure due to the lever effect, the end of the second auger shaft 71 close to the fixed cylinder 52 extends, and an extender 15 with a bracket structure wraps the extended part of the second auger shaft 71 and fixes it on the sub-bracket 14.

[0035] In order to facilitate the connection of the heat source pipeline to the horizontal auger 7, at one end of the second auger shaft 71 close to the extender 15, an air connection head 73 with a flange structure is provided, and a sealing rubber ring is provided on the flange end face of the air connection head 73.

[0036] In order to improve the rotation smoothness of the rotating cylinder 51, the rotating support mechanism 8 includes: a ring rail 81, a rotating bracket 82, a bearing seat 83, a rotating rod 84, and a support wheel 85. Among them, the ring rail 81 is an annular track structure, and the number of which is at least two groups. The ring rail 81 is externally fixed on the outer circumference of the rotating cylinder 51. Each group of ring rails 81 is supported by two groups of support wheels 85. Each group of support wheels 85 is rotatably fitted on two groups of bearing seats 83 through a rotating rod 84, and each group of bearing seats 83 is fixed on the sub-bracket 14 by a rotating bracket 82.

[0037] In order to enable the rotating cylinder 51 to have the ability of active rotation, a chain ring 13 is externally fixed on the outer circumference of the rotating cylinder 51. The chain ring 13 is meshed with a driving sprocket 12 through a chain, and the driving sprocket 12 is externally connected with a rotating power.

[0038] In order to make the rotation of the driving sprocket 12 and the inclined auger 3 only require a set of motors with lower equipment cost, a power motor 4 is fixed to the top of the inclined channel 2 through a motor bracket, and a pulley 34 is concentrically fixed to the outside of the inclined channel 2 at the top of the first auger shaft 31, and the pulley 34 and the output shaft of the power motor 4 are matched through a belt; the bottom of the first auger shaft 31 protrudes to the outside of the inclined channel 2 and is connected to a universal coupling 9 and a rod-shaped transmission shaft 11 for transmission, and a plurality of horizontal bearing seats 111 are fixed on the main bracket 1, and the horizontal bearing seats 111 are embedded in the outer periphery of the transmission shaft 11 through bearings and maintain rotational cooperation with the transmission shaft 11, and the driving sprocket 12 is concentrically fixed to the transmission shaft 11 with a key.

[0039] In order to prevent the auxiliary bracket 14 from interfering with the transmission of the chain between the driving sprocket 12 and the chain ring 13, the auxiliary bracket 14 is provided with a chain channel 16 for the chain to pass and move between the driving sprocket 12 and the chain ring 13.

[0040] Because the wet salt will be concentrated at the bottom of the drying drum 5 under the action of gravity, the air injection holes 74 serving as a drying heat source are arranged on the second auger shaft 71 with the holes facing downward.

[0041] In order to allow the wet salt fed from the feed hopper 6 to directly enter the rotating cylinder 51 , a guide plate 53 with an inclined plate structure is fixed below the feed hopper 6 , and the lower part of the guide plate 53 extends into the rotating cylinder 51 .

[0042] Brief description of the usage process:

[0043] When in use, first connect the power supply to the power motor 4, the power motor 4 rotates when powered and transmits the power to the first auger shaft 31 through the pulley 34, so that the inclined auger 3 rotates in the inclined channel 2, and the bottom of the first auger shaft 31 transmits the rotational power to the transmission shaft 11 through the universal joint 9, the transmission shaft 11 drives the driving sprocket 12 to rotate, the driving sprocket 12 drives the chain ring 13 to rotate through the chain, and the rotating cylinder 51 hooped in the chain ring 13 rotates around the fixed cylinder 52.

[0044] At this time, the wet salt is put into the feed hopper 6, and the wet salt enters from the feed hopper 6 and falls onto the guide plate 53, and enters the rotating cylinder 51 under the guidance of the guide plate 53. When the wet salt enters the rotating cylinder 51, the rotating cylinder 51 rotates around the horizontal auger 7. Through the relative motion relationship, the horizontal auger 7 rotates relative to the rotating cylinder 51. Therefore, according to the conveying principle of the conventional auger elevator, the rotating cylinder 51 in relative rotation will convey the salt from the side of the feed hopper 6 to the feed hopper 17 under the guidance of the horizontal auger 7.

[0045] Connect an external dry high-temperature air flow pipeline through the air connection head 73. The high-temperature air flow enters the inside of the second auger shaft 71 with a tubular structure from the air connection head 73 and is ejected from the air ejection holes 74 on the second auger shaft 71. The high-temperature air flow ejected from the air ejection holes 74 will dry the wet salt in the rotating cylinder 51. That is to say, the wet salt will be dried by the high-temperature air flow during the process of being conveyed from the side of the feed hopper 6 towards the material conveying hopper 17. When the lengths of the rotating cylinder 51 and the supporting horizontal auger 7 are long enough, the wet salt can be dried to the required dryness, reducing the viscosity and adhesiveness of the salt material.

[0046] The dried wet salt becomes dry salt material. After being conveyed to the material conveying hopper 17, it enters the inclined channel 2 under the inclined guidance of the material conveying hopper 17. The rotating inclined auger 3 lifts the salt material in the inclined channel 2 to the discharge port 10 (the conveying principles of the inclined auger 3 and the inclined channel 2 are the same as those of the auger elevator in the prior art, so they will not be repeated here). A receiving mechanism or a transportation mechanism is arranged below the discharge port 10 for receiving. Since the salt material lifted by the inclined auger 3 has been dried by the drying cylinder 5 when it is lifted, the viscosity and adhesiveness of the salt material after drying are greatly reduced. Therefore, when the inclined auger 3 lifts and conveys the dry salt material, compared with lifting and conveying wet salt, the adhesion of wet salt on the inclined auger 3 can be greatly reduced, preventing excessive adhesion of wet salt on the inclined auger 3 which is inconvenient for maintenance and affecting the conveying efficiency of the inclined auger 3. At the same time, in the subsequent processing operations of wet salt, some drying processes can also be reduced, simplifying the post-processing process of the salt material.

[0047] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
