Description

Technical Field

[0001] The utility model relates to the technical field of spiral hoists, in particular to a spiral hoist. Background Art

[0002] The screw elevator is a large-scale mechanical equipment that transports by changing potential energy. It is mainly used to transport powder, granular and small block materials, chemicals, etc. The rotating spiral blades push the materials for transportation. The force that prevents the materials from rotating with the screw elevator blades is the weight of the materials themselves and the friction resistance of the screw elevator casing to the materials. Therefore, during the transportation process, the screw elevator will generate a certain amount of heat. When transporting some special materials, the heat generated by the screw elevator will affect the performance of the materials to a certain extent. However, most of the existing screw elevators do not have the cooling function and cannot guarantee that the performance of the materials will not change after transportation. Utility Model Content

[0028] Combine the following Figure 1 and Figure 2 The invention discloses a spiral elevator.

[0029] like Figure 1 and Figure 2 As shown, the utility model provides a spiral elevator, including a support frame 1, a lifting pipe 2, a main shaft 3, a spiral blade 4 and a driving mechanism 5.

[0030] Among them, the lifting pipe 2 is arranged on the support frame 1, and a transportation chamber 21 and a cooling chamber 22 are arranged inside the lifting pipe 2. The transportation chamber 21 is not connected with the cooling chamber 22. A water inlet 25 and a water outlet 26 are arranged on the lifting pipe 2. The water inlet 25 and the water outlet 26 are both connected with the cooling chamber 22. A feed port and a feed port are arranged on the lifting pipe 2. The feed port and the feed port are both connected with the transportation chamber 21. The main shaft 3 is arranged in the transportation chamber 21, the spiral blade 4 is arranged on the main shaft 3, and the driving mechanism 5 is connected with the main shaft 3 to drive the main shaft 3 to rotate.

[0031] In the spiral elevator provided in this embodiment, the support frame 1 is used to provide support to ensure that the entire spiral elevator can run smoothly. The material enters the transportation chamber 21 from the feed port, and the driving mechanism 5 drives the main shaft 3 to rotate. The rotation of the main shaft 3 drives the spiral blade 4 to rotate, thereby lifting the material from the feed port to the discharge port, and the material leaves the transportation chamber 21 from the discharge port, thereby realizing the transportation function of the spiral elevator. In order to solve the problem that the existing elevator does not have a cooling function, the utility model provides a cooling chamber 22 that is not connected to the transportation chamber 21 in the lifting pipe 2. A water pump and a water tank can be used to inject water from the water inlet 25 into the cooling chamber 22. The water takes away the heat generated by the friction between the material and the lifting pipe 2 and then flows out from the water outlet 26. In this way, the heat of the lifting pipe 2 can be reduced, that is, the heat of the material can be reduced, thereby realizing the cooling function, avoiding the influence of heat on the performance of the material, ensuring that the performance of the material remains unchanged after transportation, ensuring the good quality of the material, and improving the yield rate, so that the material can better enter the next production process.

[0032] In some embodiments, the lifting pipe 2 includes a transport pipe 23 and a cooling pipe 24. The cooling pipe 24 wraps the transport pipe 23. The length of the cooling pipe 24 is less than the length of the transport pipe 23. The part of the transport pipe 23 that is longer than the cooling pipe 24 is set as an installation part 27. A cooling cavity 22 is formed between the inner wall of the cooling pipe 24 and the outer wall of the transport pipe 23. The interior of the transport pipe 23 is a transport cavity 21. The overall structure is more compact, which can save the space occupied by the entire spiral hoist.

[0033] In some embodiments, the driving mechanism 5 includes a motor seat 51, a reduction motor 52 and a transmission member 53. The motor seat 51 is arranged on the mounting portion 27, and the reduction motor 52 is arranged on the motor seat 51. The reduction motor 52 is connected to the main shaft 3 through the transmission member 53, which can drive the main shaft 3 to rotate more smoothly.

[0034] In some embodiments, the transmission member 53 includes a driving sprocket, a driven sprocket and a transmission chain. The reduction motor 52 is connected to the driving sprocket, and the main shaft 3 is connected to the driven sprocket. The driving sprocket is connected to the driven sprocket through the transmission chain, which can more smoothly transmit power to the main shaft 3, allowing the main shaft 3 to rotate more smoothly.

[0035] In some embodiments, the screw elevator also includes a feed seat 6, which is arranged on the upper side of the lifting pipe 2. The feed seat 6 is provided with a feed channel, which penetrates the feed seat 6 in a vertical direction. The feed channel is connected to the feed port. By setting the feed seat 6, the material can be more conveniently transported to the transport chamber 21.

[0036] In some embodiments, the spiral elevator also includes a grate mechanism 7, which includes a grate seat 71, a grate door plate 72 and a plurality of grate rods 73. The grate seat 71 is arranged above the feed seat 6, and the grate seat 71 is provided with a material distribution channel, which penetrates the grate seat 71 in a vertical direction, and the material distribution channel is connected to the feed channel. A material distribution port is provided on one side of the grate seat 71, and the grate door plate 72 is rotatably connected to the grate seat 71 to open or close the material distribution port. A plurality of grate rods 73 are evenly spaced on the grate seat 71, and one end of the grate rod 73 is connected to the grate seat 71, and the other end of the grate rod 73 is inclined downward toward the side of the material distribution port.

[0037] Specifically, the gaps between the multiple grate bars 73 are gaps for materials to pass through. By setting the grate seat 71, the materials can be added to the feed seat 6 more evenly, and some larger impurities cannot enter the gaps between the multiple grate bars 73, so they are screened out and leave the material distribution channel through the material distribution port, thereby realizing the screening function. In addition, the grate door plate 72 is rotatably connected to the grate seat 71. When screening and distribution of materials is not required, the grate door plate 72 can be closed to allow all materials to enter the material distribution channel and the feed channel, which has better adaptability and is more convenient to use.

[0038] In some embodiments, the screw elevator also includes a discharge seat 8, which is arranged on the lower side of the mounting portion 27. The discharge seat 8 is provided with a discharge channel, which penetrates the discharge seat 8 in a vertical direction. The discharge channel is connected to the discharge port. By setting the discharge seat 8, the material can be more conveniently discharged from the transport cavity 21.

[0039] In some embodiments, the screw elevator also includes a material guide seat 9, which is arranged on the lower side of the material discharge seat 8. The material guide seat 9 is provided with a material guide channel, which passes through the material guide seat 9 obliquely along the vertical direction. The material guide channel is connected with the material discharge channel. The material guide seat 9 has a guiding function and can lead the material to the area where it needs to be placed, which is more convenient to use.

[0040] In some embodiments, a water inlet pipe and a water outlet pipe are provided on the cooling pipe 24. The water inlet pipe is connected to the water inlet 25, and the water outlet pipe is connected to the water outlet 26. The water inlet pipe and the water outlet pipe are sealed by a flange assembly, which has a better sealing effect without affecting the water inlet and outlet.

[0041] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
