Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of chemical pulp preheating equipment, and particularly relates to a steaming bin reinforced material pushing rotor. BACKGROUND

[0002] At the present stage, with the state limiting waste paper import, the decline of waste paper raw materials will inevitably need to be supplemented by wood materials. Paper pulp production using wood materials as raw materials requires paper pulp manufacturers to change the existing production mode. At present, many domestic papermaking enterprises are undergoing transformation and upgrading. However, the investment scale of chemical pulp production lines is large, and the approval is relatively strict. Therefore, many papermaking enterprises now tend to invest in chemical mechanical pulp production lines.

[0003] The production process of the chemical mechanical pulp production line necessarily needs wood chip and bamboo chip pre-steaming equipment to pre-steam the wood chips, thereby facilitating subsequent process treatment. Therefore, the wood chip pre-steaming equipment is particularly important at this time. The steaming bin is an ideal wood chip pre-steaming equipment.

[0004] Wood chips enter the steaming bin body in the form of chips and need to stay in the bin body for a certain period of time. Therefore, the steaming bin body is generally high in height, and the wood chips entering the bin are relatively dry. After encountering steam, the wood chips will expand sharply and increase in volume. After the volume of the wood chips increases, it is easy to be extruded with the inside of the bin body and form an overall plug from the bottom of the material collection cone upwards, causing "bridging", which leads to the failure of the wood chip bin to discharge normally. In addition, the conventional material collection cone inside the steaming bin needs to arrange personnel to enter the bin body for maintenance after the effective volume rate of the bin body and "bridging", which is dangerous and time-consuming, thereby affecting the operation of the entire production line.

[0005] With the continuous improvement of production capacity, the diameter and height of the steaming bin are also increasing to meet the demand for production capacity. A larger diameter and height of the steaming bin require a larger torque when the material pushing rotor pushes the wood chips to rotate. The traditional material pushing rotor is relatively thin, as shown in FIG. 1. Under this working condition, it is easy to cause the material pushing rotor to deform, warp, bend or even break. To meet the working condition of a larger torque and ensure the normal operation of the equipment, the material pushing rotor needs to have a higher strength. The previous rotor structure needs to be optimized and the strength needs to be improved to meet the working condition requirements. Figure 1 Utility model content

[0006] The utility model provides a steaming bin reinforced material pushing rotor, which is used to solve the deficiencies described in the prior art.

[0007] The technical scheme adopted by the utility model is as follows:

[0008] ​The utility model provides a kind of steaming bin reinforced type poking rotor, including main cutter body and blade, the main cutter body includes cantilever and middle cylinder, cantilever is symmetrically located in the outer wall of middle cylinder, blade is arranged in the outer wall of middle cylinder and is located above cantilever, and reinforcing plate structure is equipped on cantilever.Cantilever is relatively long itself, and deformation, warping is easy to occur, so it needs to be strengthened, to adapt to the existing large capacity steaming bin.

[0009] As a preferred scheme of the utility model, the reinforcing plate structure is arranged between the cantilever and the outer wall of the middle cylinder and forms a triangular support structure. The triangular structure is stable and can provide stronger and more stable support.

[0010] As a preferred scheme of the utility model, the reinforcing plate structure includes a front reinforcing plate, a middle reinforcing plate and a rear reinforcing plate. The front reinforcing plate, the middle reinforcing plate and the rear reinforcing plate are sequentially assembled into a reinforcing plate. The end of the reinforcing plate close to the middle cylinder is welded to the outer wall of the middle cylinder. The end of the reinforcing plate close to the cantilever is welded to the cantilever. The reinforcing plate, the cantilever and the outer wall of the middle cylinder form a cavity. The cavity structure can provide stable support for the main cutter body with less weight increase, thereby improving the overall strength of the main cutter body.

[0011] As a preferred scheme of the utility model, the blade includes an upper bent blade and a lower bent blade. The upper bent blade and the lower bent blade are spliced and welded into a triangular blade body. The end of the triangular blade body is fixed to the outer wall of the middle cylinder. The triangular blade body has a shape similar to an airfoil. Compared with the old blade, the blade has a larger stirring area. The material at the position of the blade is more easily dispersed.

[0012] As a preferred scheme of the utility model, the cross section of the triangular blade body gradually decreases in the direction of extending outward from the middle cylinder. The end of the triangular blade body close to the middle cylinder is more robust. The cross section gradually decreases when extending outward, thereby reducing the resistance while ensuring the strength transition.

[0013] As a preferred scheme of the utility model, there is a cavity between the upper bent blade and the lower bent blade. The cavity is used to reduce the weight of the blade, thereby achieving the purpose of increasing the overall strength with less weight.

[0014] As a preferred scheme of the utility model, a steam pipe is arranged on the outer wall of the middle cylinder. The steam pipe is located above the cantilever. The steam pipe is in communication with a steam pipeline installed in the middle cylinder. The gas outlet of the steam pipe faces downward. The arrangement of the steam pipe can fully pre-steam the material at the bottom of the steaming bin and the middle cylinder, which is beneficial to the processing and production of the subsequent process.

[0015] As a preferred scheme of the utility model, the outer wall of the middle cylinder is provided with an air hole, the steam pipeline is provided with an air outlet hole at the part located in the middle cylinder, the air inlet of the steam pipe is communicated with the cavity of the middle cylinder through the air hole, and the air outlet hole is communicated with the cavity of the steam pipe.

[0016] As a preferred scheme of the utility model, the steam pipe is a semicircular pipe, and the semicircular pipe cover is welded on the outer wall of the middle cylinder.

[0017] As a preferred scheme of the utility model, the installation part of the steam pipeline and the middle cylinder is provided with a lip-shaped sealing element, so that steam leakage from the bottom of the stirring rotor is prevented, and steam flow from the steam inlet pipeline is ensured.

[0018] The utility model changes the structure of the original stirring rotor, adds a triangular support structure between the cantilever and the middle cylinder, can improve the overall strength under the premise of increasing smaller weight, also changes the blade structure, uses a triangular blade body to improve the stirring strength and stirring amount, and also sets up a steam pipe to fully pre-steam the materials at the bottom of the steaming bin and the middle cylinder, which is beneficial to the processing and production of the later stage.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] A steam chamber reinforced feed rotor, such as Figure 2 As shown, it includes a main blade body 1 and a blade 2. The main blade body 1 includes a cantilever 11 and a central cylinder 12. The cantilever 11 is symmetrically located on the outer wall of the central cylinder 12. The blade 2 is disposed on the outer wall of the central cylinder 12 and located above the cantilever 11. A reinforcing plate structure is provided on the cantilever 11. The cantilever itself is relatively long and is prone to deformation and warping, so it needs to be reinforced to be suitable for existing large-capacity steam chambers.

[0030] The reinforcing plate structure is disposed between the cantilever 11 and the outer wall of the middle cylinder 12, forming a triangular support structure. For example... Figure 2 , 3 As shown in Figure 5, specifically, there is a front reinforcing plate 31, a middle reinforcing plate 32, and a rear reinforcing plate 33. These three plates are sequentially assembled to form a reinforcing plate. The end of the reinforcing plate near the middle cylinder is welded to the outer wall of the middle cylinder, and the end of the reinforcing plate near the cantilever is welded to the cantilever. The reinforcing plate, the cantilever, and the outer wall of the middle cylinder form a cavity. Figure 2 As can be seen, the height of the reinforcing plate gradually decreases as it extends outward, forming a triangular support structure. This cavity structure provides stable support for the main blade body with minimal weight increase, thereby improving the overall strength of the main blade body.

[0031] In practice, steel plates can be bent directly to make reinforcing plates, which are then assembled and welded together. The parts have a simple structure and are easy to process and produce.

[0032] To further enhance the strength of the feeding rotor, the blade structure has been changed. The original blade was a steel plate cutting structure; the blade 2 in this application includes an upper bending blade 21 and a lower bending blade 22, as shown below. Figure 2 and 4 As shown, the upper folding blade 21 and the lower folding blade 22 are welded together to form a triangular blade body. There is a cavity between the upper folding blade 21 and the lower folding blade 22. This cavity is designed to reduce the weight of the blade itself, achieving a significant increase in overall strength with only a small increase in weight. The ends of the triangular blade body are fixed to the outer wall of the middle cylinder. The triangular blade body resembles an airplane wing shape, providing a larger material-dispersing area compared to older blade designs, making it easier to break up material at the blade's location.

[0033] And the triangular cutter body gradually reduces in cross section in the direction of extending outward from the middle cylinder, the end of the triangular cutter body close to the middle cylinder is more robust, and the cross section gradually reduces when extending outward, which reduces the resistance and ensures the equal strength transition.

[0034] The steaming bin needs to be connected with steam to steam the materials in the bin body during work, and the old type of stirring rotor has upper air inlet, and the bottom of the bin body and the stirring rotor cylinder cannot be fully pre-steamed, in order to realize the full pre-steaming of the bottom of the bin body and the stirring rotor cylinder, Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown in the figure, the gas hole is arranged on the outer wall of the middle cylinder 12, the steam pipe 5 is provided with a gas outlet hole 51 in the part located in the middle cylinder, and the steam pipe 4 is arranged on the outer wall of the middle cylinder, the steam pipe is located above the cantilever, and the steam pipe can use a semicircular pipe which is clamped and welded on the outer wall of the middle cylinder, the gas inlet of the steam pipe 4 communicates with the cavity of the middle cylinder through the gas hole, the gas outlet hole communicates with the cavity of the steam pipe, and the gas outlet of the steam pipe 4 faces downward. The arrangement of the steam pipe can fully pre-steam the materials at the bottom of the steaming bin and the middle cylinder, which is beneficial to the processing and production of the later process.

[0035] In order to prevent steam from leaking from the bottom of the stirring rotor, and ensure that the steam flows from the steam pipe, as shown in the figure, Figure 6 The installation part of the steam pipe and the middle cylinder is provided with a lip seal 6, and the installation of the stirring rotor in the steaming bin is as shown in the figure. Figure 7

[0036] The steam in the steam pipe 5 enters the cavity of the middle cylinder from the gas outlet hole and enters the steam pipe 4 from the gas hole, and is discharged from the gas outlet of the steam pipe 4 to the bottom of the steaming bin and the middle cylinder, so as to pre-steam the materials at the place.
