Problems solved by technology

The problem at this time is that the hot air that just came out of the air duct on the left has a high temperature and a fast flow rate, which leads to the curing of the fireproof glue on the left side quickly, while the curing on the right side is slow, and the left and right drying temperature of the glue surface has a large error, but The glue on the glass surface is initially a water-like liquid. If the wind speed is too high, the glue surface will be wrinkled and the glue will be blown from the left to the right, resulting in different thicknesses of the left and right glue layers. If the wind speed is low, the wind will not blow it. left side

Embodiment 1

[0038] Such as Figure 1~2 As shown, a kind of internal guide type flow equalizing pipe, one end of the flow equalizing pipe 1 is a closed end 12, and the other end is an open end 11, and the open end 11 is connected with an air inlet pipe 9 to make the air flow to the flow equalizing pipe 1. At least one outlet air hole 2 is provided between the open end 11 and the closed end 12 of the flow equalizing pipe 1 so that the air is discharged to the outside of the flow equalizing pipe 1, and each outlet air hole 2 contains a plurality of air outlet holes 2 .

[0039] The flow equalizing pipe 1 is provided with a deflector 3 connected to the downstream end of the air flow inside the air outlet hole 2. Since the air outlet hole 2 has a certain length in the direction of the air flow, the downstream end of the air flow is the air outlet 2. In the present invention, the direction words such as left and right are only relative to the accompanying drawings; The angle α between the hol...

Embodiment 2

[0042] On the basis of Embodiment 1, in order to make the air output of each air outlet hole 2 consistent, further detailed limitations are made on the internal guide type flow sharing pipe 1, as follows.

[0043] Such as Figure 1~3 As shown, a plurality of the air outlet holes 2 in each row are evenly arranged on the flow equalizing pipe 1, and all the air outlet holes 2 have the same shape and size, that is, all the air outlet holes 2 are exactly the same hole.

[0044] Starting from the first air outlet hole 2 at the upper opening end 11 of the flow equalizing pipe 1, at every interval of 200-400 mm, the angle between the deflector 3 and the air outlet 2 increases by a gradient, and the increment of each gradient 1 to 5°. Specifically, in each air outlet hole 2, the distance N between the head and the tail of two adjacent air outlet holes 2 is 40-60 mm, preferably N is 50 mm, along the air flow direction, the air is discharged from the first Starting from the hole 2, the...

Embodiment 3

[0048] On the basis of Example 2, such as Figure 4~5 shown, where Figure 5 The middle dotted line part is the deflector 3 inside the tube, which is generally invisible from the outside.

[0049] The flow equalizing pipe 1 is a square pipe, and the upper end surface of the square pipe is provided with two discharge air holes 2, and the two discharge air holes 2 are arranged in a staggered arrangement. Among the two discharge air holes 2, two adjacent air discharge holes 2 The horizontal distance between the beginning and the end is 1 / 2 or half of the distance between the beginning and the end of two adjacent air outlets in each row. The meaning of this sentence is: any air outlet in any row 2 are all arranged between the two adjacent air outlet holes 2 in the other row before and after it, for example, if the distance N between the head and the tail of each row of adjacent two air outlet holes 2 in embodiment 2 is 50mm, Then in the two air outlet holes 2, the horizontal dis...

Abstract

The invention relates to an inward-inducing type flow equalization tube and an application thereof. The inward-inducing type flow equalization tube is characterized in that one end of the flow equalization tube is a closed end while the other end is of an opening end, a wind inlet duct is connected to the opening end to enable wind current to flow to the flow equalization tube, at least one row of wind holes are arranged between the opening end and the closed end of the flow equalization tube to enable the wind to flow out of the flow equalization tube, inducers connected with wind current downstream ends inside the wind holes are arranged in the flow equalization tube, the angle between the inducers and the wind holes is greater than 0 degree and smaller than 90 degrees along the wind flow direction, and the angle between a flow equalization board and the wind holes is increased sequentially to enable wind volume of the wind holes to be consistent. The wind volume induced from the wind holes is consistent, and uniform wind feeding or heat supplying can be realized; the inward-inducing type flow equalization tube is simple in manufacturing, low in cost and remarkable in effect.

Description

technical field [0001] The invention relates to an air outlet pipe, in particular to an internally guided flow equalizing pipe and its application. Background technique [0002] In many occasions or equipment, pipes are used to convey air or heat flow, and in many cases, the requirements for uniform air supply or heat flow are high. For example, in a fire-resistant vitrification machine, whether heat flow can be evenly conveyed directly affects the quality of glass. [0003] For example, the patent application No. 201120561294.7 discloses an oxygen equalizing tube, and the pore diameter gradually increases from the open end to the closed end. That is, uniform oxygen output is achieved by increasing the pore size. However, in practice, along the flow direction of the wind from the air inlet of the pipe, the flow velocity of the wind on the inner wall of the pipe is from large to small, and the pressure is from small to large. In order to meet the requirement of consistent a...
