Description

Technical Field

[0001] This utility model relates to the field of conditioner technology, and in particular to a vertical dual-axis differential conditioner. Background Technology

[0002] As a device for hydrothermal exchange of feed and steam, the conditioner mainly mixes materials and steam through the impact and tumbling of the rotor blades. It transfers the moisture and heat from the steam to the feed, softening and cooking it to meet the requirements of subsequent feed forming processing. The more thoroughly the feed is conditioned during the forming process, the less energy is required for forming, and the higher the quality of the formed feed.

[0003] As conditioners become larger, the ratio of steam to feed is different when the machine is first started. Often, the feed needs to be conditioned to a specified temperature by the conditioner before it can be considered qualified feed. The feed that was initially prepared at the start of the machine is unqualified and is called "machine head feed".

[0004] Referring to Chinese patents CN205962778U and CN212035952U, current dual-shaft conditioners all have horizontally arranged rotating shafts. They can only transport materials from the inlet to the outlet and stir the materials in the process. Therefore, the material at the head of the machine cannot be fully conditioned from the inlet to the outlet. As a result, the material at the head of the machine needs to be returned to the previous process and re-entered into the conditioner for conditioning. This not only increases the labor intensity of workers but also increases the production cost caused by rework and reduces production efficiency. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a vertical dual-shaft differential speed conditioner to solve the problem that the conditioner in the prior art can only convey material from the inlet to the outlet, resulting in insufficient conditioning and the need for rework of the head material.

[0006] To achieve the above and other related objectives, this utility model provides a vertical dual-shaft differential conditioner, including a base, a cylinder on the base, a first rotating shaft and a second rotating shaft arranged longitudinally side by side inside the cylinder, the first rotating shaft being located above the second rotating shaft, the first rotating shaft and the second rotating shaft rotating in opposite directions, a first blade spaced apart outside the first rotating shaft, a second blade spaced apart outside the second rotating shaft, the first blade and the second blade being staggered.

[0007] In one embodiment of the present invention, the first rotating shaft and the second rotating shaft are respectively provided with a first gear and a second gear at their outer ends extending out of the cylinder, and the first gear and the second gear mesh with each other.

[0008] In one embodiment of the present invention, the first rotating shaft or the second rotating shaft is driven to rotate by a variable frequency motor.

[0009] In one embodiment of the present invention, the diameter of the first blade is larger than the diameter of the second blade.

[0010] In one embodiment of the present invention, a feed inlet is provided at one upper end of the cylinder, and a discharge outlet is provided at the lower end of the other end of the cylinder.

[0011] In one embodiment of the present invention, the first rotating shaft is provided with spiral blades at the end near the feed inlet.

[0012] In one embodiment of this utility model, a gate is provided at the discharge port.

[0013] In one embodiment of this utility model, a plurality of steam ports are also provided above the cylinder.

[0014] As described above, the vertical dual-shaft differential conditioner of this utility model has the following beneficial effects:

[0015] 1. This utility model features a vertically arranged dual shaft with opposite rotation directions. During operation, the upper first shaft pushes material from the inlet to the outlet, while the lower second shaft returns material from the outlet to the inlet. This allows the material to circulate and condition repeatedly within the cylinder, extending the conditioning time to a certain extent and making the conditioning more thorough and uniform. Simultaneously, after the machine starts working, due to the return action of the second shaft, the material gradually accumulates at the end plate near the inlet, preventing material from initially being discharged from the outlet and thus solving the problem of material at the machine head.

[0016] 2. By providing complete spiral blades on the end of the first rotating shaft near the feed inlet, this utility model can prevent material from piling up at the feed inlet and also prevent steam from escaping from the feed inlet. Attached Figure Description

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] Please see Figures 1-5 This utility model provides a vertical dual-shaft differential conditioner, including a base 1, on which a cylinder 2 is provided. A first rotating shaft 3 and a second rotating shaft 4 are arranged longitudinally side by side inside the cylinder 2. The first rotating shaft 3 is located above the second rotating shaft 4. The first rotating shaft 3 and the second rotating shaft 4 rotate in opposite directions. A first blade 31 is arranged at intervals outside the first rotating shaft 3, and a second blade 41 is arranged at intervals outside the second rotating shaft 4. The first blade 31 and the second blade 41 are staggered.

[0026] This invention features two axes arranged vertically, with opposite rotation directions. (See reference...) Figure 5 During operation, the first rotating shaft 3 at the top pushes the material, while the second rotating shaft 4 at the bottom returns the material, allowing the material to circulate and condition repeatedly within the cylinder. This extends the conditioning time to a certain extent, making the conditioning more thorough and uniform, and also solves the problem of material at the machine head.

[0027] To achieve opposite rotation directions for the first rotating shaft 3 and the second rotating shaft 4, the first rotating shaft 3 and the second rotating shaft 4 are respectively provided with a first gear 5 and a second gear 6 extending out of the cylinder 2, and the first gear 5 and the second gear 6 mesh with each other.

[0028] Furthermore, either the first rotating shaft 3 or the second rotating shaft 4 is driven to rotate by a variable frequency motor. The motor of the conditioner adopts variable frequency control, which can adjust the conditioning effect by changing the speed, thereby promoting the mixing of materials, water, and steam within the conditioning cylinder.

[0029] Furthermore, the diameter of the first blade 31 is larger than the diameter of the second blade 41. On the one hand, using two blade sizes can provide different conditioning effects, allowing the material to be conditioned better and more uniformly; on the other hand, the inner diameter of the cylinder 2 is matched with the size of the blades, and the smaller diameter of the lower blade 41 makes the volume of the lower part of the cylinder 2 smaller, which can reduce the deposition of material at the bottom of the cylinder 2 and promote the material to be pushed upward by the second blade 41 to the first blade 31, driving the repeated circulation of the material.

[0030] Furthermore, a feed inlet 21 is provided at one upper end of the cylinder 2, and a discharge outlet 22 is provided at the lower end of the other end of the cylinder 2.

[0031] Furthermore, the first rotating shaft 3 is provided with a spiral blade 32 at the end near the feed inlet 21. By using a complete spiral blade 32 in the feed inlet 21 area, material accumulation at the feed inlet can be prevented, and steam can also be prevented from escaping from the feed inlet.

[0032] Furthermore, a gate is provided at the discharge port 22. The gate at the discharge port 22 can close the discharge port 22, keeping the material inside the cylinder and extending the conditioning time as needed.

[0033] Furthermore, multiple steam ports 23 are provided on the top of the cylinder 2 to ensure sufficient steam supply.

[0034] Instructions for use: See reference Figure 5 When the conditioner is working normally, the first rotating shaft 3 pushes the material from the feed inlet 21 to the discharge outlet 22. After the material enters the cylinder 2, some of the material falls directly and is then pushed towards the feed inlet 21 by the second rotating shaft 4, circulating and accumulating at the end plate near the feed inlet 21. The other part of the material is pushed towards the discharge outlet 22 by the first rotating shaft 3. Under the action of gravity, the material moves towards the discharge outlet 22 while falling, and is pushed back towards the feed inlet 21 by the second rotating shaft 4, thus realizing the circulation of the material. Based on this principle, when the conditioner first starts working, material will gradually accumulate at the end plate near the feed inlet 21 of the cylinder 2, and no material will be discharged from the discharge outlet 22. As the accumulated material gradually increases, material will begin to be discharged from the discharge outlet 22 when it accumulates to the vicinity of the discharge outlet 22.

[0035] When the conditioner stops production, the feed inlet 21 stops feeding and controls the motor to rotate in the opposite direction. At this time, the second rotating shaft 4 will push the material from the direction of the feed inlet 21 to the direction of the discharge outlet 22, so as to achieve the purpose of emptying the material in the cylinder 2.

[0036] In summary, this invention features a vertically arranged dual-shaft configuration with opposite rotation directions. During operation, the upper first shaft pushes material from the inlet to the outlet, while the lower second shaft returns material from the outlet to the inlet. This allows the material to circulate and condition repeatedly within the cylinder, extending the conditioning time and resulting in more thorough and uniform conditioning. Simultaneously, after operation begins, the return material from the second shaft causes material to gradually accumulate near the inlet end plate, preventing initial discharge from the outlet and resolving the issue of material buildup at the machine head. Therefore, this invention effectively overcomes the shortcomings of existing technologies and possesses significant industrial application value.

[0037] The terms used in this specification, such as "upper", "lower", "left", "right", "front", "back", "middle" and "one", are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of implementation of this utility model.

[0038] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
