Description of the invention () Manmin field: The present invention relates to a device for manufacturing various papers from fiber materials by aerodynamic methods, especially in the paper industry A device for supplying a fiber suspension to a forming wire. 1 Background: The aerodynamic method of papermaking can be roughly divided into the following main steps: grinding the fiber material and dispersing it (that is, separating the material to be ground into individual fibers and forming a suspended state) Fiber); forming a fiber layer on a forming wire; pressing and drying. In order to make the paper uniform in thickness and width when leaving the papermaking machine, the uniformity of the fibers deposited on the forming wire must meet the equivalent requirements, but this requirement is for the manufacture of a wide paper. Difficult to meet. In this case, in order to maintain the productivity, multiple devices (ie, spreaders) capable of separating the fiber material into individual fibers are used to supply the suspension flow to a device capable of forming a single suspension flow, of which a single The overhang flow must also provide uniformly distributed fibers over the full width of the forming wire. A device for drying the paper from a fibrous material of the ocean is known. One of the devices includes a cavity with a perforated bottom, and a shaft wheel, a housing, and a brush body. The chamber has an input channel and an output channel, and includes a concentrator disposed on the input channel. As disclosed in USSR Auth〇r, sCertificate No. 111〇845 3D21H5 / 26 published on August 30, 1984, the main body of the concentrator is bent radially from the supply side to the supply direction and a waste collection bin is arranged in its Large-radius wall, the above main page 2 This paper size is applicable to China National Standard (CNS) A4 specification (210 X 297 mm) -------- · ----------.— Order --------- (Please read the notes on the back before filling out this page) 579403 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention Divided into two parts for transmitting a fiber stream and removing air, the partition is erected on the fiber output side. The air removal portion is provided with a plurality of separation blades. The concentrator has an increased portion on its side, and the suspended fibers are supplied and configured with a rotating baffle. When a suspended stream enters the concentrator, the 'concentrator removes large particles into a waste collector and separates the suspended stream into a concentrated fiber stream and an air stream. The air is removed and the suspended stream is supplied to a rotor with a brush body. When the brush body is operated at the bottom of the perforation, additional damage to the fiber coil occurs. The separated fibers pass through the perforations at the bottom and settle on the forming wire. However, although the dispersed main body is arranged directly next to the forming net by the shaft wheel with the brush body, the structure uniformity of the produced paper is messy, because the entire suspended fiber passes through the perforations at the bottom of the chamber for a unit of time. It cannot be precisely controlled. Such a device generally cannot produce a uniform suspension flow to produce a wide paper at an increasing rate in the aerodynamic formation process, that is, a plurality of diffusers are combined into a single suspension flow, which covers the entire width of the forming net All have uniformly distributed fibers. Another apparatus for forming a dry web includes a cylindrical fiber supply tube having a continuous groove for supplying dispersed fibers to a continuous forming web. For example, USSR Auth〇r, s Certificate No. 1 154400, 4D21H5 / 26, published on May 7, 1985. The part of the groove of the pipe body is gradually tapered toward the moving net. The pipe body is set at an angle of less than 90 degrees relative to the axis of the wire mesh ', and the tilt angle is adjustable. The pipe body is provided with a device for uniformly spreading the fibers across the width of the row of nets, in the form of a set of measuring rings joined along the pipe body, each ring forming a fishing body. The suction box is placed on the web page 10 @ (cns) A4 --------: ------------- order --------- (please first Read the notes on the back and fill in this page) 579403 A7 B7 printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Below the description of the invention () to provide a controlled vacuum generation. The uniform distribution of fibers over the width of the row of nets requires the same number of fibers per unit of tube length to be spread at the beginning and at the end of the row of nets. This state is provided by the tapering of the tube body. The adjusting ring controls the size of the opening of the groove at any point along the entire length of the pipe body for detailed adjustment of convection. The above-mentioned device is simple in design. However, a lot of labor will be wasted. The device needs to be adjusted when the forming rate is different for each specific situation. In addition, the device cannot provide a uniform fiber flow from multiple dispensers. A device for refibrillating a fibrous material is considered to be closest to the applicant of the present invention, and it was disclosed in USSR Author's Certificate No. 746007, 2D21D1 / 34, published July 7, 1980. This device includes a cylindrical body, a shaft wheel, and a stator having a design such as a concentric nest tube with a chuck partition. The partition plate and the disk form an annular duct extending in the axial direction of the main body, whereby the suspended fibers from the respective diffusers are supplied. Coaxial groove rings are fixed on both sides of the disc. The axle wheel contains two support discs which are stationary outside the stator via bearings. The support disc is connected to blades fixed around it, thereby forming a fan. This fan blade is attached with a shaft disk. The disc carries concentric grooved rings on its sides. The concentric ring of the shaft wheel is coaxial with the concentric ring of the stator. A filter screen is placed a distance around the axle wheel. The device is configured with a channel for supplying and removing the suspended fiber. The device combines a spreading function and generates a suspended flow of uniformly spreading fibers across the width of the forming web. Suspension flow from each diffuser is supplied to the axle wheel through the tube. The flow through the shaft wheel blades and the rotating ring of the shaft wheel and the stationary ring of the stator are not the same.

The last uniform precipitation and therefore the manufacturer of the papermaking equipment can satisfy the needs of the papermaker in virtually any available width. However, as described above, combining the function of scatter and the distribution of suspended fibers in the width of the forming net reduces the uniformity of the paper-forming structure and makes the design of the entire device more complicated. The presence of a filter screen reduces the production capacity of the device. 1 Clear purpose and summary: Therefore, the present invention provides a device for enhancing the structural uniformity of the formed paper, and the structure of such a device appears simple. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs according to the present invention, the presenter is a device for supplying suspended fibers to a papermaking machine forming net, the device includes a cylindrical body including a plurality of input pipes, It is used to receive the suspended fiber stream; and an output pipe is used to lead the received suspended stream out of the cylinder body. A shaft wheel has an outer surface and a shaft length, and is arranged in the cylinder body. Each of the plurality of shaft wheel blades' has an axial dimension, which is provided in the radial direction of the shaft wheel. In addition, the input pipe and the output pipe are provided outside the cylindrical royal body, and their installation directions are tangent to the direction in which the shaft wheel rotates. According to a special embodiment of the present invention, the channel pattern of the input pipeline can be designed as a diffusion / convergence channel. With respect to the cylindrical body, the diffusion-convergence channel diffuses in the axial direction and converges in the radial direction.

Description of the invention () The convergence channel has a diffusion part and a convergence part, where the former side A is equivalent to the axial direction of the cylinder body and the latter direction is equivalent The radial direction of the cylindrical body. According to this embodiment, the suspended flow can be dispersed substantially in the axial direction before entering the cylindrical body. According to another embodiment of the present invention, the output pipe includes a curved portion, and the curved portion is located at an outlet of the cylinder body. The deflection portion causes the output pipe to go in a direction opposite to the rotation direction of the shaft wheel. The axial dimension of the shaft wheel blade does not exceed half of the shaft wheel shaft length. In addition, the axle wheel blades are arranged on the surface of the axle wheel in a staggered order to improve the agitation of suspension. The position of the input pipe and the output pipe outside the main body and the tangent to the rotation direction of the shaft wheel enable the floating flow to be freely supplied by a plurality of diffusers into the active agitation area generated by the rotation of the shaft wheel in the cylinder body. The diffusion-convergence-shaped input pipe enables the suspension flow entering the cylindrical body to be dispersed by an additional axis, thereby accelerating the completion of the mixing process. In addition, if a curved portion is provided at the outlet of the main body, the fiber bundle in the suspended flow can be prevented from being sent to the output pipe, and it is also prevented from being deposited on the forming wire. It is clear that the fiber bundle is taken away by the recirculation of the suspension stream and is mixed again by the shaft wheel. If the blade length is less than half of the length of the shaft wheel, and the intersection is set on the outer surface of the shaft wheel, then the suspended flow can be dispersed again through the additional shaft #, and the mixing of the suspended flow can be more perfect. Finally, the suspension flow is fed from the output duct to the forming wire to form uniformly dispersed fibers across the width of the paper.

The fan blade (not shown) is supplied by the diffuser (not shown) to the input of the device (please read the precautions on the back before filling this page) A, 铪. The right is as shown in Figure 2, The input pipe 2 is designed as a diffusion _JI channel, and the supply of the suspended stream is concentrated in the direction of the radiation toward the cylindrical body 1 and diffuses in its I * direction. Because of this—as a result of re-dispersion, the suspended stream can be roughly Scattered in its axial direction and supplied into the space between the main body 1 and the shaft wheel 3. The suspended flow flows in the cylindrical body 1 and reaches the blade 4 provided on the shaft wheel 3 (see section 3) A moving agitation area generated by the blade 4 draws a part of the entire flow into a rotating (or circulating) flow around the axle wheel 3. A static pressure drop is generated by the blade 4 and additional circulation The flow is presented by the vortex between the blades, thereby agitating the suspended fibers strongly. If the output pipe 5 shown in FIG. 2 has a curved portion 6, the suspended flow in the bend P wound 6 is turned by centrifugal force , To avoid the possibility of fiber integration when entering the output pipe 5. The fiber It will be taken away by the circulating flow, scattered by the blades 4 of the axle wheel 3 and mixed again. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, therefore, 'the uniformly distributed fibers are provided over the entire width of the forming net— Suspended flow is generated by a relatively simple device. This suspended flow can form a wide paper with enhanced uniformity.
