Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
Example 1
An air collecting box is formed by transversely connecting two boxes 101 and 201 as shown in figure 1, and a gate valve 3 for communicating or disconnecting the adjacent boxes is arranged at the joint of the adjacent boxes. The box body 101 is provided with an air inlet 102 and two air outlets 103; the box 2012 is provided with an air inlet 202 and two air outlets 203. Each air outlet is provided with an air outlet butterfly valve (not shown in figure 1) for controlling the opening and closing of the air outlet.
The gate valve belongs to the existing mature products on the market and can be divided into a manual type, a pneumatic type and an electric type according to different power sources. The gate valve is mainly used for a fluid conveying system to play roles in diversion, interception and the like. In some application occasions, the air tightness of the gate valve is also required to be higher.
In the embodiment, the gate valve is mainly used for connecting or disconnecting the gas flow between adjacent boxes, plays a role in reducing the air volume or increasing the air volume, and has no particularly strict requirement on air tightness, so that the gate valve adopts a simple structure, and comprises a frame body 301 fixed at the joint of the adjacent boxes, an insert plate 302 sliding in the frame body, and an electric driving mechanism (not shown in fig. 1) for driving the insert plate to slide. The sliding direction of the inserting plate can be vertical or horizontal, but the horizontal sliding is more convenient for the arrangement of the electric driving mechanism. The electric driving mechanism can be an electric cylinder with the end part fixed on the plugboard, or a motor can drive the lead screw to rotate to realize the sliding of the plugboard, or other electric driving mechanisms which can drive the plugboard to move.
As is easily understood by those skilled in the art, when the air intake of the air collecting box is constant, the larger the internal space of the box body is, the more the air outlets are, the smaller the generated air pressure is. The bellows disclosed in the present application is designed based on this principle. The gate valve is used for adjusting the size of the inner space of the box body; the quantity of the air outlets is adjusted by opening and closing the air outlets through the air outlet butterfly valves.
For example, in this embodiment, when the two boxes are separated into two independent boxes by the gate valve, and the two independent boxes are both supplied with fluid with a certain air volume by the independent fans, the fluid can only flow through the corresponding box and then flow out from the corresponding air outlet. When the inserting plate of the inserting plate valve is moved away under the driving of the electric driving mechanism, the two box bodies are combined into a whole, and at the moment, if only one fan is started and four air ports corresponding to the two box bodies are opened, the air pressure of the air outlet is far smaller than that of the former case; at this time, if one of the four air outlets is closed, the air pressure of the air outlet is higher than that of the case that all the four air outlets are opened.
Example 2
An air supply system of a fireproof glass tempering furnace is shown in figure 2 and comprises a fan 4, an air duct 5, an air collecting box and an air grid pipe 6, wherein one side of the air duct 5 is connected with the fan 4, the other side of the air duct is connected with the air collecting box, one side of the air grid pipe 6 is connected with the air collecting box, and the other side of the air grid pipe is connected with a tempering section 7 of the glass tempering furnace.
The air collecting box is disclosed in embodiment 1, an air inlet of each box body is connected with an independent fan 4, each air outlet is communicated with a toughening section 7 of the glass toughening furnace through an air grid pipe, and a plurality of air blowing holes are formed in the connecting side of the air grid pipe and the toughening section.
When the fireproof glass with the thickness of 5mm or 6mm is produced, high wind pressure is needed in the toughening stage, the gate valve is closed, and the air collecting box is divided into two independent boxes. Two fans are started simultaneously, and four air outlet butterfly valves are all opened.
When 8mm or 10mm fireproof glass is produced, the air pressure is required in the toughening stage, the gate valve is opened, the two boxes are combined into a large box, and the butterfly valve of one or two air outlets in the four air outlets is closed (specifically according to the air pressure requirement).
When the fireproof glass with the thickness of more than 10mm is produced, low wind pressure is needed in the toughening stage, the gate valve is opened, the two boxes are combined into a large box, and the four air outlet butterfly valves are all opened.
The start and stop of the fan connected with the air inlet of each box body, the opening and closing of the air inlet butterfly valve of the air outlet of each box body and the opening and closing of the gate valve between the adjacent box bodies are automatically controlled by a PLC according to a set program, and when the fireproof glass with different thicknesses is produced, the thickness parameters can be directly set through a human-computer interface. In the actual use process, the air quantity of the fan, the number of the boxes and the number of the air outlets of each box can be selected according to actual requirements. PLC is the programmable logic controller that current fire prevention glass tempering furnace has been equipped with, consequently, the scheme that this application provided has only add push-pull valve and several wind gap butterfly valves, can directly reform transform on current fire prevention glass tempering furnace basis to reform transform with low costs, energy-conserving effectual.
It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present disclosure.
