Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a screw conveyor. Background Art

[0002] Rubber powder needs to go through multiple processing steps during the production process, among which the effective transportation of materials is one of the key links. Traditional screw conveyors usually only have basic conveying functions, that is, conveying materials from one end to the other, but in actual production, the special processing requirements of rubber powder, such as drying and cooling, are often not effectively met.

[0003] First, traditional screw conveyors usually operate only through the exhaust holes of the equipment when performing drying or cooling. This treatment method is not only lacking in specificity, but also difficult to accurately control the processing conditions, such as temperature and airflow distribution, resulting in energy waste and low processing efficiency. In some cases, the rubber powder may have uneven quality due to uneven drying, affecting the consistency of the final product.

[0004] In addition, conventional equipment often faces the problem of material agglomeration when processing rubber powder. Since rubber powder has small particles and is easily affected by environmental factors such as humidity, agglomeration will seriously affect the subsequent mixing and molding processes, further reducing product quality. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a screw conveyor to solve the above-mentioned problems.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a screw conveyor, comprising a base and four supporting legs installed at the bottom, the base is equipped with a ventilation pipe, the ventilation pipe is equipped with spiral blades, the ventilation pipe is fixedly equipped with a collection trough at the bottom position of the spiral blade, the collection trough is equipped with a feed port, the ventilation pipe is equipped with a discharge port corresponding to the top position of the spiral blade, the top of the ventilation pipe is equipped with a vibration motor, a plurality of air outlets are provided on the ventilation pipe, an L-shaped baffle is provided at the position corresponding to the air outlet on the spiral blade, a guide plate is fixedly connected to the lower wall surface of the horizontal end of the L-shaped baffle, the guide plate is composed of an arc block and a rectangular block, and the L-shaped baffle is fixedly connected to the spiral blade through a connecting mechanism.

[0007] Preferably, one end of the arc block on the guide plate is fixedly connected to an end adjacent to the rectangular block on the guide plate, the arc block on the guide plate is located on the side of the rectangular block on the guide plate away from the ventilation pipe, and the outer arc diameter of the arc block on the guide plate gradually increases from top to bottom.

[0008] Preferably, a plurality of auxiliary blocks are fixedly connected to a side wall of the rectangular block on the guide plate close to the inner side of the arc-shaped block on the guide plate.

[0009] Preferably, the auxiliary block is a V-shaped elastic block, and the horizontal height of the bottom end of the lower wall surface of the auxiliary block is lower than the horizontal height of the lower wall surface of the rectangular block on the guide plate.

[0010] Preferably, the connecting mechanism includes an adjustment hole, a bolt and a threaded hole. Two adjustment holes are symmetrically provided on the side wall of the vertical end of the L-shaped baffle away from the spiral blade. Two threaded holes are provided on the outer wall of the spiral blade at positions corresponding to the two adjustment holes. Bolts are movably clamped inside the two adjustment holes, and the bolts are threadedly connected to the corresponding threaded holes.

[0011] Preferably, the bolt can move up and down inside the adjustment hole.

[0012] Compared with the prior art, the utility model provides a screw conveyor with the following beneficial effects:

[0013] 1. By setting up ventilation ducts, air outlets, external hot air blowers or cold air blowers, and L-shaped baffles and guide plates on the spiral blades, the effect of efficient drying or cooling of raw materials is achieved. When the equipment is connected to an external hot air blower or cold air blower, the hot air or cold air is discharged through the air outlet on the ventilation duct, and the guide plate on the L-shaped baffle can guide the airflow and guide the airflow downward to the raw materials on the spiral blades, thereby improving the drying or cooling efficiency of the raw materials. At the same time, the special design of the arc block on the guide plate can also make the airflow reflux twice, greatly improving resource utilization and reducing energy consumption.

[0014] 2. By setting up the connection mechanism (adjustment hole, bolt and threaded hole), the purpose of quickly installing the L-shaped baffle and adjusting its installation height is achieved, so that it can be applied to the processing of various types of materials, which greatly improves the practicality of the equipment. Specifically, the combination of bolts and threaded holes enables the L-shaped baffle to be quickly installed on the spiral blade, which provides convenience for the assembly and maintenance of the equipment. The design that the bolt can move up and down in the adjustment hole allows the operator to flexibly adjust the height of the L-shaped baffle according to the characteristics and processing requirements of different materials. For example, for some materials that require strong airflow guidance, the L-shaped baffle can be adjusted to a lower position to ensure that the guide plate can better guide the airflow discharged from the air outlet; for some materials that are sensitive to airflow, the L-shaped baffle can be adjusted to a higher position to reduce the impact of airflow on the material. This height-adjustable design enables the equipment to adapt to the processing of materials of different types and specifications, improving the versatility and adaptability of the equipment.

[0015] 3. By setting auxiliary blocks on the guide plate, the effect of avoiding the agglomeration of raw materials and improving the processing quality is achieved. The auxiliary block is a V-shaped elastic block, and the horizontal height of the bottom end of its lower wall is lower than the horizontal height of the lower wall of the rectangular block on the guide plate. During the operation of the equipment, with the vibration of the equipment, the auxiliary block can squeeze and break up the raw materials on the spiral blades, effectively avoiding the problem of unqualified processing caused by the agglomeration of raw materials and ensuring the quality of the finished product.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5A screw conveyor comprises a base 1 and four supporting legs 2 installed at the bottom, and the four supporting legs 2 provide a stable support for the base 1. A ventilation pipe 3 is installed on the base 1, and a spiral blade 9 is installed on the ventilation pipe 3. A collecting trough 4 is fixedly installed at the bottom of the spiral blade 9 on the ventilation pipe 3, and a feeding port 5 is provided on the collecting trough 4. A discharge port 7 is provided at the top position of the ventilation pipe 3 corresponding to the spiral blade 9, and a vibration motor 8 is provided on the top of the ventilation pipe 3. A plurality of air outlets 6 are arranged on the ventilation pipe 3, and an L-shaped baffle 10 is arranged at the position corresponding to the air outlet 6 on the spiral blade 9. A guide plate 11 is fixedly connected to the lower wall surface of the horizontal end of the L-shaped baffle 10, and the guide plate 11 is composed of an arc block and a rectangular block. The L-shaped baffle 10 is fixedly connected to the spiral blade 9 through a connecting mechanism.

[0024] When in use, the raw materials to be processed are fed into the interior of the aggregate trough 4 through the feed port 5, and then the vibration motor 8 is started to drive the equipment to operate. The raw materials in the aggregate trough 4 will be vibrated and lifted by the spiral blades 9. The processed raw materials will be transported to the designated position through the discharge port 7. At the same time, the ventilation duct 3 can be connected to an external hot air blower or cold air blower through a hose according to actual needs. The hot air or cold air can be discharged in conjunction with the air outlet 6 on the ventilation duct 3, thereby completing the drying or cooling of the raw materials on the spiral blades 9.

[0025] One end of the arc block on the guide plate 11 is fixedly connected to the end adjacent to the rectangular block on the guide plate 11. The arc block on the guide plate 11 is located on the side of the rectangular block on the guide plate 11 away from the ventilation pipe 3, and the outer arc diameter of the arc block on the guide plate 11 gradually increases from top to bottom.

[0026] When in use, because the position of the L-shaped baffle 10 corresponds to the air outlet 6, when the air outlet 6 discharges hot air or cold air, the guide plate 11 on the L-shaped baffle 10 will guide it. Since the guide plate 11 is composed of an arc block and a rectangular block, and the outer arc diameter of the arc block on the guide plate 11 gradually increases from top to bottom, the guide plate 11 can not only guide the airflow discharged from the air outlet 6 downward, thereby improving the drying or cooling efficiency of the raw materials on the spiral blades 9, but also the arc block on the guide plate 11 can perform secondary reflux on the airflow discharged from the air outlet 6, thereby greatly improving resource utilization and reducing energy consumption.

[0027] A plurality of auxiliary blocks 12 are fixedly connected to a wall surface of one side of the rectangular block on the guide plate 11 close to the interior of the arc-shaped block on the guide plate 11 .

[0028] The auxiliary block 12 is a V-shaped elastic block, and the horizontal height of the bottom end of the lower wall of the auxiliary block 12 is lower than the horizontal height of the lower wall of the rectangular block on the guide plate 11 .

[0029] Since the horizontal height of the bottom end of the lower wall of the auxiliary block 12 is lower than the horizontal height of the lower wall of the rectangular block on the guide plate 11, and the auxiliary block 12 is elastic, the auxiliary block 12 can squeeze and break up the raw materials on the spiral blade 9 as the equipment vibrates during use, thereby avoiding the problem of unqualified processing due to agglomeration of raw materials.

[0030] The connecting mechanism includes an adjustment hole 13, a bolt 14 and a threaded hole 15. Two adjustment holes 13 are symmetrically provided on the side wall of the vertical end of the L-shaped baffle 10 away from the spiral blade 9, and two threaded holes 15 are provided on the outer wall of the spiral blade 9 at positions corresponding to the two adjustment holes 13. Bolts 14 are movably clamped inside the two adjustment holes 13, and the bolts 14 are threadedly connected to the corresponding threaded holes 15.

[0031] The bolt 14 can move up and down inside the adjustment hole 13 .

[0032] The L-shaped baffle 10 can be quickly installed through the bolts 14 and the threaded holes 15, and the installation height of the L-shaped baffle 10 can be adjusted by cooperating with the adjustment holes 13, so as to be suitable for processing various types of materials, greatly improving the practicality of the equipment.

[0033] Working principle:

[0034] When in use, first connect an external cold air blower or hot air blower to the ventilation duct 3 as needed, then adjust the position of the L-shaped baffle 10 in conjunction with the connecting mechanism, and finally put the raw materials to be processed into the collecting trough 4 through the feed port 5, and start the vibration motor 8 to drive the equipment to run. During this period, the guide plate 11 on the L-shaped baffle 10 can guide and reflux the airflow discharged from the air port 6, thereby greatly improving the processing efficiency of the equipment, and the auxiliary block 12 on the guide plate 11 can also break up the raw materials immediately, avoiding the problem of incomplete processing due to clumping of raw materials, affecting the effect of the finished product.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
