Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and in particular to an automatic defoaming device for a white water pool under the wire mesh. Background Technology

[0002] In the papermaking process, foam is easily generated in the white water tank below the wire mesh. Existing technologies typically use defoamers to reduce the surface tension of the foam, causing it to burst and thus defoaming. However, existing technologies usually add defoamers at fixed intervals or according to a fixed ratio with white water, which cannot achieve precise addition. If too little defoamer is added, defoaming will not be achieved; if too much is added, excess defoamer will remain in the paper, affecting its performance. In view of these technical problems, this invention proposes an automatic defoaming device for the white water tank below the wire mesh, used to detect the amount of foam in the white water in real time, thereby precisely adding defoamer. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an automatic defoaming device for a white water pool under a net, which aims to solve the technical problem of inaccurate addition of defoamer in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic defoaming device for a white water tank under a net includes a dosing tank, a dosing pump, a foam sensor, and a support; the support includes a fixed rod, a first vertical rod connected to the fixed rod, a horizontal rod connected to the first vertical rod, a second vertical rod connected to the horizontal rod, and a support rod connected to the second vertical rod; the foam sensor is mounted on the support rod.

[0006] Furthermore, the bracket is installed at the overflow outlet of the white water pool below the net.

[0007] Furthermore, in the aforementioned automatic defoaming device for the white water pool under the net, a vertical guide hole is provided on the fixed rod, and the first vertical rod passes through the vertical guide hole on the fixed rod.

[0008] Furthermore, in the aforementioned automatic defoaming device for the white water pool under the net, a vertical guide hole is provided on the support rod, and a second vertical rod passes through the vertical guide hole of the support rod.

[0009] Furthermore, in the aforementioned automatic defoaming device for the white water pool under the net, the first vertical rod and the second vertical rod are respectively connected to the horizontal rod through a guide sleeve. Each guide sleeve has a horizontal guide hole and a vertical guide hole. The first vertical rod and the second vertical rod pass through the vertical guide hole of the corresponding guide sleeve, and the horizontal rod passes through the horizontal guide holes of the two guide sleeves.

[0010] Furthermore, in the aforementioned automatic defoaming device for the white water pool under the net, the horizontal bar, the first vertical bar, and the second vertical bar are all straight pipes.

[0011] Furthermore, in the aforementioned automatic defoaming device for the white water pool under the net, the probe of the foam sensor is 3-5 cm higher than the overflow port.

[0012] Furthermore, in the aforementioned automatic defoaming device for the white water pool under the net, the dosing pump is a metering pump.

[0013] Beneficial effects: This utility model provides an automatic defoaming device for white water pools under netting, which has at least the following advantages compared with the prior art:

[0014] (1) Precise defoaming: The device is equipped with a foam sensor, which can accurately detect the foam floating on the surface of the white water pool under the wire in real time. When the foam content is detected to exceed the preset value, the dosing pump will automatically start to add defoamer, avoiding the problem of adding too much or too little defoamer. This effectively eliminates foam and prevents the paper performance from being affected by defoamer residue.

[0015] (2) Flexible adjustment: The bracket structure is cleverly designed. The fixed rod is equipped with a vertical guide hole, which makes it easy to adjust the height of the first vertical rod and thus adjust the overall height of the bracket. The support rod also has a vertical guide hole, which can directly adjust the height of the foam sensor. The first and second vertical rods are connected to the horizontal rod through a guide sleeve with a horizontal guide hole and a vertical guide hole, which can realize the horizontal adjustment of the horizontal rod and the second vertical rod, and can flexibly adjust the horizontal position of the foam sensor to adapt to the white water pool under the net with different sizes and working conditions.

[0016] (3) Structural optimization: The horizontal bar, the first vertical bar, and the second vertical bar all adopt a straight tube design and are hollow structures. This greatly reduces the weight of the support itself, improves the ease of assembly, reduces transportation and installation costs, and makes it less prone to deformation during use, ensuring the stability and reliability of the device and extending its service life.

[0027] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model is further described in detail below. It should be understood that the specific embodiments described herein are merely for explaining this utility model and are not intended to limit this utility model.

[0028] Please see Figures 1 to 3 This utility model provides an automatic defoaming device for a white water pool under a net. The accompanying drawings are for illustrative purposes only and are not proportional to an actual product. The drawings only depict structures relevant to the present utility model; some conventional structures are not specifically shown. The terms "first," "second," etc., used herein are merely different names for similar structures for ease of explanation and are not intended to limit this application.

[0029] An automatic defoaming device for a white water tank under a net includes a dosing tank, a dosing pump, a foam sensor, and a support frame. The support frame includes a fixed rod, a first vertical rod connected to the fixed rod, a horizontal rod connected to the first vertical rod, a second vertical rod connected to the horizontal rod, and a support rod connected to the second vertical rod. The foam sensor is mounted on the support rod. The dosing tank is used to hold defoamer. The inlet pipe of the dosing pump is connected to the dosing tank, and the outlet pipe of the dosing pump is connected to the white water tank under the net. When the foam sensor detects that the foam content in the white water tank under the net exceeds a preset value, the dosing pump is activated to add a certain amount of defoamer to the white water tank.

[0030] Preferably, the bracket is positioned at the overflow outlet of the white water tank below the net. Foam is relatively concentrated at the overflow outlet; positioning the bracket here makes it easier for the foam sensor to detect foam, ensuring the accuracy of the detection results.

[0031] Furthermore, a vertical guide hole is provided on the fixing rod, through which the first vertical rod passes. This arrangement facilitates adjustment of the first vertical rod to a suitable height, thereby adjusting the overall height of the bracket. The attached diagram schematically shows a locking hole (threaded hole) at the guide hole on the fixing rod. A locking bolt is provided at the locking hole; tightening the locking bolt will fix the first vertical rod. Several threaded holes (not shown in the figure) can be provided on the first vertical rod for connection with the locking bolt; since the weight borne by the bracket is not large, the first vertical rod may also not have threaded holes, and the locking bolt, after being tightened, can still secure the first vertical rod through static friction. The various guide holes mentioned below can also be locked in the same way (i.e., locked by locking bolts), and the same structural principle will not be repeated below.

[0032] Furthermore, a vertical guide hole is provided on the support rod, through which the second vertical rod passes. This arrangement facilitates adjustment of the support rod's height, thereby directly adjusting the height of the foam sensor on the support rod.

[0033] Furthermore, the first and second vertical rods are each connected to the horizontal rod via a guide sleeve. Each guide sleeve has a horizontal guide hole and a vertical guide hole. The first and second vertical rods pass through the vertical guide holes of their respective guide sleeves, while the horizontal rod passes through the horizontal guide holes of both guide sleeves. This arrangement allows for horizontal adjustment of the horizontal rod relative to the first vertical rod, as well as horizontal adjustment of the second vertical rod relative to the horizontal rod. Both adjustment methods can adjust the horizontal position of the foam sensor.

[0034] Furthermore, the horizontal bar, the first vertical bar, and the second vertical bar are all straight tubes. That is, the horizontal bar, the first vertical bar, and the second vertical bar are all hollow structures, which significantly reduces the weight of the support, makes assembly easier, and makes it less prone to deformation during use. Although the attached diagram shows a square tube, it can also be a round tube or a straight tube of other shapes; this is not a limitation here.

[0035] Furthermore, the probe of the foam sensor is 3-5 cm higher than the overflow port. This design allows the foam sensor to effectively detect foam floating on the surface of the white water tank below the net, thus enabling precise addition of defoamer. For ease of understanding, the attached diagram schematically illustrates the overflow pipe, and the connection point between the overflow pipe and the white water tank below the net is the overflow port.

[0036] Preferably, the dosing pump is a metering pump, which can accurately control the amount of defoamer added, ensuring that the amount of defoamer used is neither too much nor too little.

[0037] In practical applications, the fixing rod is set on the side wall of the white water tank below the net, near the overflow port. The positions of the first vertical rod, the horizontal rod, the second vertical rod, and the support rod are adjusted and fixed so that the probe of the foam sensor is slightly higher than the overflow port. The foam sensor detects the foam content in the white water in real time. When the foam sensor detects that the foam content in the white water exceeds the preset value, the dosing pump is started, injecting a certain amount of defoamer into the white water tank below the net.

[0038] It should be noted that this application seeks protection for the structure of the automatic defoaming device for the white water tank below the net. In practical applications, how to achieve automatic control through PLC, the PLC control program, and the amount of chemicals added are all determined by the actual production situation, and this application does not impose any limitations.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
