Description

Technical Field

[0001] This utility model relates to the technical field of quality preservation devices for feed processing, and in particular to a dual-axis equal-diameter quality preservation device. Background Technology

[0002] Conditioners are generally used in the conditioning section of feed processing to keep materials warm for extended periods to improve maturation, especially for powdered feed, as this directly affects the quality of the finished product. Traditional conditioners use a single-cylinder, single-shaft structure, resulting in a low filling coefficient and poor material kneading effect; furthermore, the geared motor uses a direct-drive structure, making the geared motor susceptible to significant impact from material fluctuations, thus affecting its service life. Utility Model Content

[0003] The technical problem to be solved by this utility model is: In order to overcome the above-mentioned technical problems, this utility model provides a dual-axis equal-diameter conditioner, which can effectively improve the conditioning time and the kneading effect of the material, improve the gelatinization degree, and facilitate granulation.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a dual-shaft equal-diameter tempering device, including a cylinder, a main tempering shaft, a secondary tempering shaft, a variable frequency motor, and a reducer. The reducer has a single input shaft and two output shafts, and the two output shafts of the reducer rotate in the same direction. The output shaft of the variable frequency motor is drivenly connected to the input shaft of the reducer. The two output shafts of the reducer are respectively drivenly connected to the main tempering shaft and the secondary tempering shaft. The main tempering shaft and the secondary tempering shaft are arranged side by side in parallel, and both the outer circumferences of the main tempering shaft and the secondary tempering shaft are provided with screws. The helical blades of the main tempering shaft and the auxiliary tempering shaft are staggered, with the same rotation direction and outer diameter. The reducer has a housing containing a multi-stage speed-reducing transmission gear set and a driven output gear set. The input shaft of the reducer is driven by one of its output shafts via the multi-stage speed-reducing transmission gear set, and this output shaft is driven by the other output shaft via the driven output gear set. The input and output shafts are located on opposite sides of the housing, and a partition separates the input and output shafts. The partition does not provide a seal, but only separates the input and output; the flow of lubricating oil is not restricted by the partition. The output shaft of the reducer and the multi-stage speed-reducing transmission gear set are located on the same side of the partition, while the two output shafts and the driven output gear set are located on the other side of the partition. The housing is filled with lubricating oil. The main tempering shaft and the auxiliary tempering shaft are located inside a cylinder, which has an inlet and an outlet.

[0005] Preferably, the level of the lubricating oil in the gearbox is just above the level of the primary gear in the multi-stage reduction gear set. Ensure lubrication of the input shaft.

[0006] To improve the filling coefficient, preferably, the outer diameters of both the main and secondary heat-conditioning shafts are matched with the inner diameter of the cylinder.

[0007] Preferably, the reducer is a three-stage parallel shaft reducer.

[0008] Preferably, the speed reducer is connected to the variable frequency motor via a belt, and the main heat-cooling shaft and the auxiliary heat-cooling shaft are each connected to the speed reducer via a coupling.

[0009] To improve the filling coefficient, the cylinder is preferably a double-cylinder structure with partially overlapping parallel sections.

[0010] The upstream process configuration of the conditioner connects a feeder and a conditioner. The feeder is driven by a feed motor to feed material to the conditioner. The conditioner has a steam inlet, which mixes the material flowing to the conditioner with the steam input from the steam inlet of the conditioner, thus completing the mixing of the material.

[0011] A level sensor is installed at the feed inlet, which serves to protect against excessive material levels. When the material level reaches the upper limit in the storage tank, the level sensor will stall and issue a signal. The feed rate can be reduced by adjusting the speed of the variable frequency feed motor through a program or manually. When the level sensor stalls for a set time, the variable frequency motor can be stopped. The motor will restart after the stall signal is released, preventing machine blockage and ensuring smooth operation.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a dual-shaft equal-diameter quality retainer, which adopts a dual-shaft equal-diameter large cylindrical structure. The material conveying direction of the main conditioning shaft and the secondary conditioning shaft is the same, the material is first-in-first-out, and it will be biased to one side to achieve material extrusion, resulting in a longer shelf life and better gelatinization. The outer diameters of the main conditioning shaft and the secondary conditioning shaft are matched with the inner diameter of the cylinder, which can improve the filling coefficient. While optimizing the dual-shaft co-directional conditioning shaft, the transmission structure of the gearbox has also been optimized to improve the reliability of operation.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] like Figure 1-2 As shown, this utility model discloses a dual-shaft equal-diameter tempering device, comprising a cylinder 1, a main tempering shaft 2, a secondary tempering shaft 3, a variable frequency motor 5, and a reducer 6. The reducer 6 has a single input shaft 6-1 and two output shafts 6-2, with the two output shafts 6-2 rotating in the same direction. The output shafts 6-2 of the variable frequency motor 5 are drive-connected to the input shaft 6-1 of the reducer 6. The reducer 6 is drive-connected to the variable frequency motor 5 via a reducer pulley 8, a belt 7, and a motor pulley 9. The main tempering shaft 2 and the secondary tempering shaft 3 are each drive-connected to the reducer 6 via a coupling 10.

[0024] The two output shafts 6-2 of the reducer 6 are respectively connected to the main quenching and tempering shaft 2 and the auxiliary quenching and tempering shaft 3. The main quenching and tempering shaft 2 and the auxiliary quenching and tempering shaft 3 are arranged side by side in parallel, and both the outer circumferences of the main quenching and tempering shaft 2 and the auxiliary quenching and tempering shaft 3 are provided with helical blades 4. Figure 7 As shown, the helical blades 4 of the main heat treatment shaft 2 and the helical blades 4 of the secondary heat treatment shaft 3 are interleaved, and their rotation direction and outer diameter are the same.

[0025] like Figure 4-6 As shown, the reducer 6 has a housing 6-3, inside which there is a multi-stage speed reduction transmission gear set 6-4 and a driven output gear set 6-5. The reducer 6 is a three-stage transmission parallel shaft reducer, and it is a high-speed input and low-speed output reducer. The input shaft 6-1 of the reducer 6 is driven by one of its output shafts 6-2 via a multi-stage speed reduction gear set 6-4. This output shaft 6-2 is driven by the other output shaft 6-2 via a driven output gear set 6-5. The input shaft 6-1 and output shaft 6-2 of the reducer 6 are respectively located on opposite sides of the housing 6-3. A partition 6-6 is provided inside the housing 6-3 to separate the input shaft 6-1 and output shaft 6-2. The partition 6-6 does not provide a seal; it only separates the input and output. The flow of lubricating oil is not restricted by the partition 6-6. The output shaft 6-2 of the reducer 6 and the multi-stage speed reduction gear set 6-4 are located on the same side of the partition 6-6. The two output shafts 6-2 and the driven output gear set 6-5 of the reducer 6 are located on the other side of the partition 6-6. The housing 6-3 is filled with lubricating oil, and the oil level inside the housing 6-3 is just above the primary gear in the multi-stage speed reduction gear set 6-4. The height of the lubricating oil reduces the churning of internal gears and high-speed gears within the lubricating oil, effectively lowering the oil temperature. Simultaneously, it lubricates the input shaft 6-1, improving the operational reliability of the reducer 6. Under the premise of controllable cost, it is necessary to solve the problems of excessively high oil temperature in the reducer 6 and lubrication of the input shaft 6-1. A partition 6-6 is used to divide the housing 6-3 into chambers, allowing the input and output shafts 6-2 to be arranged horizontally. The partition 6-6 provides installation space and a fixed position for the horizontal arrangement of the input and output shafts 6-2. Without changing the external dimensions of the reducer, the input and output shafts 6-2 are arranged horizontally, meeting the multi-stage speed reduction requirements of the output speed. At the same time, the lubricating oil immersion height is improved, reducing the problem of oil tank temperature rise and ensuring long-term, low-speed, high-load operation of the retainer of this utility model.

[0026] The main conditioning shaft 2 and the auxiliary conditioning shaft 3 are located inside the cylinder 1, which has a feed inlet 1-1 and a discharge outlet 1-2. Starting the variable frequency motor 5 enables the main conditioning shaft 2 and the auxiliary conditioning shaft 3 to rotate in the same direction, allowing material to flow from the feed inlet 1-1 to the discharge outlet 1-2. The conditioner controls the speed of the variable frequency motor 5 to meet different filling coefficient requirements, achieving a long maturation process and ensuring sufficient maturation time for the material.

[0027] The cylinder 1 is a double-cylinder structure with partial spatial overlap and parallel arrangement, which can match the stirring range of the main conditioning shaft 2 and the secondary conditioning shaft 3 as much as possible, thereby improving the filling coefficient.

[0028] like Figure 3As shown, the upstream process configuration of the conditioner connects the feeder 11 and the conditioner 12. The feeder 11 is driven by the feeder motor 11-1 to feed the material to the conditioner 12. The conditioner 12 has a steam inlet 12-1, which mixes the material flowing to the conditioner 12 with the steam input into the steam inlet 12-1 of the conditioner 12, thus completing the mixing of the material. Figure 3 The upper arrow indicates the feeding direction, and the lower arrow indicates the discharging direction.

[0029] like Figure 3 As shown, a level sensor 13 is installed at the feed inlet 1-1. The level sensor 13 serves as a protection device against excessively high material levels. When the material level in the storage tank reaches its upper limit, the level sensor 13 will stall and send a signal. The feed rate can be reduced by adjusting the speed of the variable frequency feeding motor through a program or manually. When the stall time of the level sensor 13 reaches the set time, the variable frequency motor 5 can be controlled to stop running. After the stall signal of the level sensor 13 is released, the variable frequency motor 5 will restart, thus preventing machine blockage and ensuring smooth process operation.

[0030] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
