Description

Slurry structure

This creation relates to a slurry tank structure, particularly for a pulping process in wet paper forming equipment.

In the pulping process of the existing wet paper forming equipment, the pulp tank is a necessary device for storing pulp, but the conventional pulp tank often cannot keep the composition of the pulp (including plant fragments, various fibers, water and other raw materials). It can be mixed evenly and maintain a certain pulp concentration. This is because in the process of making the paper-plastic, the mold needs to be repeatedly immersed in the slurry tank and then lifted up the pulp from the slurry tank, so that the movement is repeated continuously, such as by using the method of stirring the pulp, the mold is made. The pulp process is interrupted or delayed and causes problems.

The composition of the pulp is complex and mostly insoluble. It is an urgent problem to solve the problem that the pulp is in a state of uniform mixing without using a stirring method without affecting the operation of the mold for making the paper.

In order to solve the above problems, the purpose of the present invention is to propose a sump structure for a wet paper forming apparatus which can keep the pulp in a state of uniform mixing at any time in the pulp process without affecting the operation of the mold for making the paper.

In a preferred embodiment, the tank further includes a line surrounding the bottom wall of the working area and disposed within the tank.

In a preferred embodiment, the line forms at least one vent for transporting upward gas into the tank for uniform mixing of the slurry.

In a preferred embodiment, the structure further includes a gas pump connected to the line to provide high pressure gas through the at least one vent.

In a preferred embodiment, the at least one injection port is positioned higher than the line.

In a preferred embodiment, the height of the at least one spacer is lower than the height of the slot wall of the slot.

In a preferred embodiment, the at least one partition comprises two vertical partitions for separating the loading space into one working area and two overflow areas, the two overflow areas being respectively set On opposite sides of the work area.

In a preferred embodiment, the structure further includes a recovery unit for conveying the slurry from the at least one extraction unit to the at least one injection unit.

The creation divides the loading space into a work area and an overflow area, and sets a pipeline in the work area. The gas is continuously supplied by the at least one orifice on the line to maintain uniform mixing of the pulp. The pulp with a lower concentration of the upper layer of the work area is allowed to overflow to the overflow area to maintain the concentration of the pulp for subsequent production of the paper-plastic product.

The following description of the various embodiments is set forth to illustrate the specific embodiments The directional terms mentioned in this creation, such as "upper", "lower", "before", "after", "left", "right", "inside", "outside", "side", etc., are only references The direction of the schema. Therefore, the directional terminology used is used to describe and understand the creation, and is not intended to limit the creation.

Refer to Figures 1 and 2. 1 is a top plan view of a slurry tank structure 100 in accordance with a first preferred embodiment of the present invention. 2 is a side cross-sectional view showing a slurry tank structure 100 according to FIG. 1. The sump structure 100 includes a tank body 110 and at least one injection unit 120 (although only one injection unit is illustrated in this embodiment, but not limited to other applications in which more than one injection unit 120 is disposed), at least one extraction unit 130 A line 150, a recovery unit 160, and a gas pump 170.

The trough body 110 is composed of a plurality of trough walls 112. The plurality of trough walls 112 collectively define a loading space 114 for loading a slurry. The trough body 110 is provided with at least one vertical partition 140 for The loading space 114 is divided into a working area 116 and an overflow area 118, wherein the height of the partition 140 is lower than the height of the groove wall 112 of the trough 110 (ie, the height of the trough wall 112 minus the partition 140) The height difference is H1, H1 is greater than zero), whereby when the slurry injected into the working area 116 is excessive, a portion of the slurry will overflow from the working area 116 through the partition 140 to the overflow. District 118.

The at least one injection unit 120 is configured to inject the slurry into the working area 116 through at least one injection port 125 located in the working area 116. The at least one extraction unit 130 is configured to transmit a portion through at least one extraction port 135 of the overflow area 118. The slurry is withdrawn from the overflow body 118 from the tank body 110. In this embodiment, the at least one injection unit 120 and the at least one extraction unit 130 respectively include a pump.

The line 150 is enclosed in the working area 116, preferably on the bottom channel wall 113 in the working area 116 of the tank body 110. In addition, at least one air hole 155 is formed in the pipeline 150 for conveying the upward gas into the tank body 110 to uniformly mix the slurry; in the embodiment, the pipeline 150 forms a plurality of air holes 155 along the pipeline. The length of 150 is arranged, and the gas pump 170 is connected to one end of the pipeline 150 to transmit pressurized or high-pressure gas (generally air) through at least one air hole 155 of the pipeline 150 of the bottom tank wall 113. Different gases are used to the bottom wall 113 in response to different paddles.

In order to increase the mixing degree of the contents of the slurry (such as pulp, long and short fibers, etc.), the position of the line 150 in the tank body 110 is lower than the position of the at least one injection port 125, so that the rising high pressure gas can be injected. The slurry provides a better mixing with the original slurry. Moreover, the concentration of the slurry flowing above the working zone 116 is generally low, so overflowing to the overflow zone 118 is to help maintain the concentration of the slurry of the working zone 116; and then by the extraction unit 130 The slurry in the overflow zone 118 is further withdrawn and injected into the recovery unit 160, mixed by the recovery unit 160, and then sent to the injection unit 120, and then injected into the work area 116 through the injection unit 120 to The slurry is recycled and reused.

The introduction of pressurized gas into the tank 110 through the line 150 in the working area 116 not only increases the uniform mixing of the slurry components in the tank 110. The effect is also that the paper-making mold (not shown) can be continuously moved in the slurry tank without being affected: especially because in the slurry, except for water, some substances are insoluble in water, and in this part A compound having a specific gravity greater than that of water is formed after water absorption, so that the concentration in the slurry can be effectively stabilized by the rising gas.

3 is a top plan view of a slurry tank structure 200 in accordance with a second preferred embodiment of the present invention. The slurry tank structure 200 of the second preferred embodiment differs from the slurry tank structure 100 of the first preferred embodiment in that at least one partition 140 of the second preferred embodiment includes two vertical partitions 140 for The load space 114 is divided into a working area 116 and two overflow areas 118, which are respectively disposed on opposite sides of the working area 116. The design of the working area 116 and the overflow area 118 of the above two preferred embodiments respectively produce different fluid states, which are respectively applicable to different slurries.

The above is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make some improvements and retouching without departing from the principle of the present invention. These improvements and retouchings should also be regarded as The scope of protection of this creation.
