Abstract
The utility model discloses a vacuum box, comprising a box body, a vacuum chamber and an upper bracket. The vacuum box is characterized in that the vacuum chamber is arranged inside the box body; extraction openings are arranged at one side of the box body; the upper bracket is arranged at the upper part of the box body and consists of transverse strips; and the transverse strips are connected in a welding manner. With the adoption of an optimized vacuum pipeline, the air flow direction is perpendicular to the movement direction of paper sheets and the movement direction of a screen, so that air is facilitated to pass through the paper sheets; the dewatering time is reduced; and the energy needed by the vacuum box is reduced. The upper bracket is connected in the welding manner, so that the mounting time is reduced.
Description
Technical field
The utility model relates to a kind of vacuum tank, particularly relates to the vacuum tank in a kind of papermaking machine dewatering process.
Background technology
In the field of papermaking, need dewater with vacuum tank.Wet web is compressed under differential pressure action, and the compression dehydration takes place, and air begins to penetrate paper web, and interfibrous portion of water is brought in the vacuum tank with air-flow, forms the air force dehydration.Paper web dewaters through vacuum dehydration technology can cause very high energy consumption, and the manufacturing and the set-up time of this dewatering elements are expended length simultaneously.
Summary of the invention
The utility model technical problem to be solved is to provide a kind of energy to consume vacuum tank low, that the set-up time is short.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of vacuum tank, comprise casing, vacuum chamber and upper bracket, and it is characterized in that: described vacuum chamber is located at box house; Casing one side is provided with bleeding point; Described upper bracket is located at casing top, is made up of horizontal stripe, adopts the mode of welding to connect between the horizontal stripe.
Aforesaid vacuum tank is characterized in that: the quantity of said bleeding point is 2.
Compared with prior art, the utility model has the advantages that: the direction that the vacuum line after the optimization flows air is vertical with the direction of motion of page, net, is convenient to the air penetration page, shortens dewatering time, has reduced the energy that vacuum tank needs; Upper bracket adopts the mode of welding to connect, and has shortened the set-up time.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the vacuum line figure in the utility model.
The specific embodiment
For further disclosing the technical scheme of the utility model; Now be described with reference to the accompanying drawings the embodiment of the utility model: like Fig. 1, shown in 2, a kind of vacuum tank comprises casing 1, vacuum chamber and upper bracket 3; Vacuum chamber is located at casing 1 inside, and casing 1 one sides are provided with two bleeding points 2.Upper bracket 3 is located at casing top, is made up of horizontal stripe, adopts the mode of welding to connect between the horizontal stripe, substitutes to be threaded, and has shortened the set-up time.。
On paper web and net were incumbent on support during work, the air on the paper web came out from 2 through 3 entering of net from Fig. 1.The direction that air flows is a vertical direction, and the direction of motion of page and net is horizontal direction, and both are vertical each other, and this design is convenient to the air penetration page, shortens dewatering time, has reduced the energy that vacuum tank needs.
More than, the basic design and the basic principle of the utility model have been set forth through introduction to listed embodiment.But the utility model never is limited to above-mentioned listed embodiment, and every equivalent variations, improvement of doing based on the technical scheme of the utility model reaches and deliberately become of inferior quality behavior, all should belong to the protection domain of the utility model.
Claims (2)
1. a vacuum tank comprises casing, vacuum chamber and upper bracket, it is characterized in that: described vacuum chamber is located at box house, and casing one side is provided with bleeding point, and described upper bracket is located at casing top, is made up of horizontal stripe, adopts the mode of welding to connect between the horizontal stripe.
2. vacuum tank according to claim 1 is characterized in that: the quantity of said bleeding point is 2.
