Description

Technical Field

[0001] The utility model relates to a material guide trough, in particular to an anti-grading chute. Background Art

[0002] The anti-gradation chute is a device used to transport raw materials from high to low. Its main function is to prevent the powder and granular materials in the raw materials from stratifying under the action of gravity and air buoyancy.

[0003] The commonly used anti-grading chute, during operation, mainly reduces the impact of gravity and air buoyancy on the raw materials by designing various tortuous routes, thereby achieving anti-grading.

[0004] However, in the prior art anti-grading chute, since the raw materials are in continuous motion inside the chute, there is still a certain grading problem for the raw materials. Utility Model Content

[0005] In view of the technical problem that the anti-grading chute in the prior art still has a certain grading phenomenon due to the continuous movement of raw materials inside the anti-grading chute, the utility model provides an anti-grading chute. By adding a buffer tank, the raw materials can stay briefly in the middle of the anti-grading chute, thereby avoiding raw material classification.

[0006] The technical solution of the utility model is:

[0007] An anti-grading slide pipe, comprising:

[0008] The pipe has an inlet at one end and an outlet at the other end, and is arranged in a vertical direction;

[0009] The support rod is arranged inside the pipeline and along the length of the pipeline;

[0010] Multiple spiral troughs are arranged on the support rod at equal intervals and arranged around the circumference of the support rod, with the ends of two adjacent spiral troughs close to each other;

[0011] Multiple buffer troughs are arranged on the inner wall of the pipeline and located between two adjacent spiral troughs. The top of the buffer trough is connected to the tail of one spiral trough, and the bottom of the buffer trough is connected to the head of the other spiral trough.

[0012] Optionally, a buffer plate is provided in the buffer groove.

[0013] Optionally, two buffer plates are rotatably provided in the buffer groove, and the two buffer plates can cut off the buffer groove.

[0014] Optionally, a positioning magnetic block and a rebound magnetic block are provided inside the buffer groove, and a connecting magnetic block is provided on the buffer plate;

[0015] The positioning magnetic block is located above the buffer plate, and the side close to the connecting magnetic block has opposite magnetic poles;

[0016] The rebound magnetic block is located below the buffer plate, and the side close to the connecting magnetic block has the same magnetic pole.

[0017] Optionally, both sides of the bottom of the buffer tank are inwardly contracted structures.

[0018] Optionally, the tail of the spiral trough is a structure with a gradually narrowing width.

[0019] Optionally, the number of spiral turns of the spiral trough is greater than or equal to one turn.

[0020] Optionally, a guide plate is obliquely provided at the feed inlet of the pipeline, and the guide plate is connected to the head of the spiral trough at the feed inlet of the pipeline.

[0021] Optionally, there is a gap between the top and the bottom of the buffer trough and the spiral trough.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] A pipeline is set up, and the raw materials enter from the pipeline inlet. After entering the pipeline, the raw materials slide downward in the spiral trough and slide into the buffer trough, where the raw materials are buffered and temporarily stopped. During this process, due to the height limit of the spiral trough, the powdered raw materials and granular raw materials enter the buffer trough before they are classified. In the buffer trough, the granular raw materials and powdered raw materials are also kept mixed.

[0024] In this technical solution, multiple spiral troughs and multiple buffer troughs are arranged in the pipeline, so that when the raw materials at a high place are transported to a low place, the raw materials are still in a mixed state. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Example:

[0035] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4This embodiment discloses an anti-grading chute, comprising a pipe 10, a support rod 20, a spiral trough 30, and a buffer trough 40. The support rod 20 is disposed within the pipe 10, the spiral trough 30 is disposed on the support rod 20 and is located within the pipe 10, and the buffer trough 40 is located within the pipe 10 and docked with the spiral trough 30. This embodiment primarily achieves the purpose of preventing raw material grading through the spiral trough 30 and the buffer trough 40.

[0036] Specifically, the pipe 10 is a hollow cylindrical structure, with an inlet at one end and an outlet at the other. When in use, the inlet is located at the top of the pipe 10, while the outlet is located at the bottom. A support rod 20 is positioned within the pipe 10, and its length is aligned with that of the pipe 10. The support rod 20 is located in the middle of the pipe 10.

[0037] There are multiple spiral troughs 30, all of which are installed on the support rod 20. On the support rod 20, all spiral troughs 30 are evenly distributed and all are arranged around the circumference of the support rod 20. At the same time, there is a gap between two adjacent spiral troughs 30, and a buffer trough 40 is provided between two adjacent spiral troughs 30.

[0038] The head end of the spiral trough 30 faces the inlet of the pipeline 10 , and the tail end faces the outlet of the pipeline 10 . The inner side of the spiral trough 30 is connected to the support rod 20 , and the outer side is connected to the inner wall of the pipeline 10 .

[0039] The head and tail ends of two adjacent spiral troughs 30 are on the same vertical plane. The top of the buffer trough 40 is connected to the tail of the spiral trough 30 above it, and the bottom of the buffer trough 40 is connected to the head of the spiral trough 30 below it.

[0040] In this embodiment, after entering the pipe 10, the raw materials slide downward within the spiral trough 30 and into the buffer trough 40, where they are buffered and briefly held. During this process, due to the height restriction of the spiral trough 30, the powdered and granular raw materials enter the buffer trough 40 before any grading occurs, and the granular and powdered raw materials remain mixed within the buffer trough 40.

[0041] In this technical solution, a plurality of spiral troughs 30 and a plurality of buffer troughs 40 are provided in the pipeline 10, so that the raw materials are still in a mixed state when they are transported from a high place to a low place.

[0042] In one specific embodiment:

[0043] The anti-grading chute further comprises a buffer plate 41, a positioning magnetic block 42, a rebound magnetic block 43, and a connecting magnetic block 44, disposed within each buffer trough 40. Specifically, taking the internal structure of a buffer trough 40 as an example, two buffer plates 41 are rotatably disposed on either side of the buffer trough 40. When both buffer plates 41 are horizontal, they can cut off the middle of the buffer trough 40, thereby forming a structure that intercepts raw materials and allows them to remain within the buffer trough 40.

[0044] The ends of the two buffer plates 41 that are away from each other are rotatably connected to the inner wall of the buffer groove 40 .

[0045] In this technical solution, a connecting magnet 44 is provided on the end of the buffer plate 41 away from the inner wall of the buffer groove 40, and a positioning magnet 42 and a rebound magnet 43 are provided on the inner wall of the buffer groove 40. The positioning magnet 42 is located above the buffer plate 41, and the rebound magnet 43 is located below the positioning magnet.

[0046] During installation, the magnetic pole of the positioning magnet 42 on the side closest to the buffer plate 41 is different from the magnetic pole of the upward-facing side of the connecting magnet 44, while the magnetic pole of the downward-facing side of the connecting magnet 44 is the same as the magnetic pole of the upward-facing side of the rebound magnet 43. Furthermore, when the positioning magnet 42 and the connecting magnet 44 are in contact, both buffer plates 41 are horizontal. When the connecting magnet 44 approaches the rebound magnet 43, the buffer plate 41 tilts downward.

[0047] In this embodiment, by selecting connecting magnets 44 and positioning magnets 42 of appropriate magnetic strength and attaching them together, raw materials can be buffered within the container formed by the two buffer plates 41 and the buffer trough 40. When the raw materials reach a certain volume, their weight offsets the attractive force of the connecting magnets 44 and positioning magnets 42, and the two buffer plates 41 rotate, allowing the raw materials in the buffer trough 40 to pass through the bottom thereof. After the raw materials pass through, the rebound magnet 43 causes the connecting magnets 44 and buffer plates 41 to rebound to a certain height. Combined with the attractive force of the connecting magnets 44 and positioning magnets 42, the two buffer plates 41 again block the interior of the buffer trough 40.

[0048] In another specific embodiment:

[0049] The two sides of the bottom of the buffer tank 40 are inwardly contracted to increase the pressure at the bottom of the buffer tank 40 .

[0050] In another specific embodiment:

[0051] The tail of the spiral trough 30 is a structure with a gradually narrowing width. This structure ensures that the raw materials flow evenly into the buffer trough 40 from the tail of the spiral trough 30 .

[0052] In another specific embodiment:

[0053] The number of spiral turns of the spiral trough 30 is greater than or equal to one turn. Through this design, the number of buffer troughs 40 installed can be reduced without affecting the anti-gradation effect.

[0054] In another specific embodiment:

[0055] A guide plate 11 is provided at an angle at the feed inlet of the pipeline 10 , and the guide plate 11 is connected to the head of the spiral trough 30 at the feed inlet of the pipeline 10 . The guide plate 11 is provided for the purpose of facilitating the input of raw materials onto the spiral trough 30 .

[0056] In another specific embodiment:

[0057] There is a gap between the top and bottom of the buffer trough 40 and the spiral trough 30, which can simplify the structure.

[0058] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
