[0025] The specific embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0026] In the embodiments of the present application, the window device is used to observe the powdery materials in the storage tank so as to understand the situation of the materials in real time. In this regard, in the embodiments of the present application, the field of application of the window is not specifically limited. For example, it can be used in the food industry or other industries, as long as it meets the storage device for storing powdery materials.

[0027] Refer to Figure 1 and Figure 2The embodiment of the present application provides a window device, the window device A includes a shell 10 and a guide assembly, the shell 10 is provided with a through observation port 10c and a closed space located on one side of the observation port 10c, the observation port 10c is covered by a transparent plate 20, the closed space includes a first chamber 80 and a second chamber 70 which are not connected to each other, the first chamber 80 is adjacent to the observation port 10c, a blowing nozzle 30 is provided on the partition wall between the first chamber 80 and the observation port 10c, the blowing nozzle 30 is located behind the transparent plate 20, and is used to form a wind curtain on the back of the transparent plate 20, and the second chamber 70 is used to receive external compressed air. The guide assembly is arranged in the first chamber 80 and is located between the blowing nozzle 30 and the second chamber 70, and the guide assembly has a guide air duct 90a inside, the guide air duct 90a connects the second chamber 70 and the blowing nozzle 30, and is used to guide the gas in the second chamber 70 to the blowing nozzle 30.

[0028] For example, the gas blown out of the blowing nozzle 30 can be blown in the horizontal direction of the transparent plate 20 (refer to Figure 1 In the X direction), a wind curtain can be formed on the back of the transparent plate 20 to prevent dust from adhering to the surface of the transparent plate 20. Compared with the method in which the gas blown out of the blowing nozzle 30 directly acts on the back of the transparent plate 20, a better observation line of sight is provided.

[0029] For example, an observation port that passes through the storage tank is opened on the housing 10, and the observation port 10c is covered with a transparent plate 20, and a closed space is formed on the housing 10 at the same time, the closed space includes a first chamber 80 and a second chamber 70 that are not connected to each other, and a guide assembly is arranged in the first chamber 80, and the transparent plate 20 and the guide assembly are cleverly integrated into a whole, which facilitates the subsequent installation of the window device A on the storage tank. Specifically, the housing 10 can adopt a detachable connection method (such as bolts, screws), or a fixed connection method (such as welding), which is not limited.

[0030] Exemplarily, before directing the gas to the blowing nozzle 30, it is necessary to first introduce the external compressed air into the second chamber 70 for pressure stabilization to avoid the gas generating turbulence that causes confusion when blowing the dust, and there is still the problem of obstructed vision. In this regard, in the present embodiment, a second chamber 70 is provided in a confined space so that the introduced compressed air can be pressure-stabilized in the second chamber 70 to reduce the internal gas bypass. In addition, it should be noted that the external compressed air can be connected to the second chamber 70 through a connecting pipe through the housing 10, so that the compressed air is introduced into the second chamber 70 for pressure stabilization. The above method of introducing compressed air into the second chamber 70 is only an example, but is not limited to this.

[0031] Exemplarily, the air blowing nozzle 30 is arranged behind the transparent plate 20, and the air blowing nozzle 30 is connected to the second chamber 70 through a diversion air duct 90a. The other end of the air blowing nozzle 30 is arranged in a direction away from the sealed space, so that the gas in the second chamber 70 flows towards the air blowing nozzle 30 under the guidance of the diversion air duct 90a, and then is blown out from the air blowing nozzle 30, thereby forming a dynamic air curtain on the back surface of the transparent plate 20 to blow away the dust behind the transparent plate 20, avoid the dust from adhering to the surface of the transparent plate 20, and ensure a clear line of sight in the area behind the transparent plate 20.

[0032] Exemplarily, in order to prevent dust from adhering to the surface of the transparent plate 20, it is necessary to ensure that the air blowing nozzle 30 is always in the blowing state to form a dynamic air curtain behind the transparent plate 20. For this purpose, it is necessary to continuously introduce compressed air into the second chamber 70, so that the air in the second chamber 70 continuously flows towards the diversion air duct 90a and is finally blown out through the air blowing nozzle 30, thereby forming a dynamic air curtain in the area on the back surface of the transparent plate 20, and using the pressure difference to control the flow of the gas without using a power component for driving.

[0033] Based on the window device A with the above technical features, by arranging a plurality of air blowing nozzles 30 on one side of the sealed space close to the observation port 10c, and arranging a second chamber 70 in the sealed space, and then using a diversion plate 90 arranged at intervals between the second chamber 70 and the air blowing nozzle 30 to form a diversion air duct 90a, so that the diversion air duct 90a guides the gas in the second chamber 70 to the air blowing nozzle 30, and finally the gas is blown out from the air blowing nozzle 30 along the horizontal direction of the transparent plate 20, thereby forming a dynamic air curtain behind the transparent plate 20 to blow away the dust behind the transparent plate 20, avoid the dust from adhering to the surface of the transparent plate 20, and ensure a clear line of sight in the area behind the transparent plate 20.

[0034] In one embodiment, a plurality of air blowing nozzles 30 are provided, and the plurality of air blowing nozzles 30 are distributed at the same intervals along the vertical direction of the transparent plate 20 (refer to the Y direction in Figure 1 ), and the areas of the diversion air ducts 90a formed by the intervals between adjacent diversion plates 90 are the same, so that the air volumes blown out by the air blowing nozzles 30 are kept consistent.

[0035] It should be noted that the above-mentioned "a plurality of air blowing nozzles 30" may refer to one or more than one, and specifically can be determined according to the actual situation. For example: if the size of the adopted transparent plate 20 is large, five evenly spaced air blowing nozzles 30 are required to ensure that the formed dynamic air curtain can cover the entire area behind the transparent plate 20 and ensure a clear line of sight in the area behind the transparent plate 20; if the size of the adopted transparent plate 20 is small, only two air blowing nozzles 30 need to be arranged for blowing to cover the area behind the transparent plate 20.

[0036] Exemplarily, setting the areas of the diversion air ducts 90a to be formed to be the same is to ensure that the air volume flowing from the second chamber 70 to each air blowing nozzle 30 can be kept consistent, so that a uniform air curtain can be formed behind the transparent plate 20, avoiding the situation that the line of sight is blocked in some areas due to different blowing effects of the dust caused by different air output volumes.

[0037] In one embodiment, the diversion assembly includes a plurality of diversion plates 90 distributed at intervals, and a diversion air duct 90a is defined between adjacent diversion plates 90.

[0038] Exemplarily, the diversion air ducts 90a are formed by a plurality of diversion plates 90 distributed at intervals in the first chamber 80, so that the compressed air in the second chamber 70 can be guided to the air blowing nozzles 30 and blown out from the air blowing nozzles 30, thereby forming an air curtain in the back area of the transparent plate 20.

[0039] In addition, the diversion plates 90 can be inclined or horizontally arranged, which needs to be determined according to the position of the second chamber 70. For example: referring to Figure 2 , the second chamber 70 is arranged at the lower part of the enclosed space. At this time, the diversion plates 90 are gradually inclined upward along the gas blowing direction.

[0040] In one embodiment, an air inlet 10b communicating with the enclosed space is provided on the housing 10. The air inlet 10b is connected to the second chamber 70 through an air inlet pipe 100, and a regulating valve 110 is provided on the air inlet pipe 100. The regulating valve 110 is used to regulate the air intake volume of the air inlet pipe 100.

[0041] Exemplarily, by providing an air inlet 10b communicating with the enclosed space on the housing 10 and using the air inlet pipe 100 to connect the air inlet 10b with the second chamber 70, when the external compressed air is led to the second chamber 70, the air inlet pipe is inserted into the air inlet 10b so that the air inlet pipe is connected to the air inlet pipe 100, and then the compressed air flows into the second chamber 70 through the air inlet pipe and the air inlet pipe 100. The structure is simple and the connection is convenient. At the same time, a regulating valve 110 is also provided on the air inlet pipe 100, so that according to the dust situation behind the transparent plate 20, the opening degree of the regulating valve 110 can be controlled to adjust the intake volume of the compressed air, thereby adjusting the air volume blown out by the air blowing nozzles 30.

[0042] In one embodiment, it further includes a differential pressure gauge 130, a pneumatic tube 120, and a controller 40. One end of the pneumatic tube 120 is connected to the intake pipe 100, and the other end of the pneumatic tube 120 is connected to the blowing nozzle 30. The differential pressure gauge 130 is disposed on the pneumatic tube 120 for monitoring the differential pressure between the intake pipe 100 and the blowing nozzle 30, and the differential pressure gauge 130 is electrically connected to the controller 40. The control panel of the controller 40 is embedded in the front surface of the housing 10, and the regulating valve 110 is electrically connected to the controller 40.

[0043] Exemplarily, both ends of the pneumatic tube 120 are respectively connected to the intake pipe 100 and the blowing nozzle 30, and a differential pressure gauge 130 is disposed on the pneumatic tube 120 so as to be able to monitor the differential pressure between the intake pipe 100 and the blowing nozzle 30, and transmit the monitored data into the controller 40. By comparing with the value preset in the controller 40, the opening degree of the regulating valve 110 is controlled, so that corresponding adjustment can be made according to the dust situation behind the transparent plate 20. For example, when there is more dust staying in the area behind the transparent plate 20, the air volume blown out by the blowing nozzle 30 is blocked at this time, resulting in a differential pressure between the blowing nozzle 30 and the intake pipe 100. At this time, the differential pressure gauge 130 detects the data and transmits it to the controller 40. Then the controller 40 controls the regulating valve 110 to allow more compressed air to enter the second chamber 70, thereby enhancing the air output volume to blow away the dust; when there is a turbulent flow formed in the area behind the transparent plate 20, the controller 40 controls the regulating valve 110 to reduce the compressed air entering the second chamber 70, thereby reducing the air output volume and avoiding the occurrence of turbulent flow phenomenon.

[0044] In one embodiment, it further includes a lighting member 60 for illuminating the observation port 10c. The lighting member 60 is disposed on the side of the observation port 10c away from the enclosed space, and the lighting member 60 is electrically connected to the controller 40. In this way, the lighting member provided can illuminate the area of the observation port 10c to provide lighting in the dark, facilitating personnel to observe the situation inside the storage tank.

[0045] In one embodiment, it further includes an infrared detection member 50. The infrared detection member 50 is disposed on the surface of the housing 10 and is electrically connected to the controller 40.

[0046] Exemplarily, by disposing the infrared detection member 50 on the surface of the housing 10, when someone approaches, the infrared detection member 50 detects the signal and transmits it to the controller 40, and then the controller 40 controls the lighting member 60 to automatically turn on the lighting, without the need for manual operation, which is more convenient to use.

[0047] In one embodiment, an electrical interface 10a communicating with the sealed space is provided on the housing 10. The electrical interface 10a is used for electrically connecting an external power cord to the controller 40. In this way, it is convenient for the external power cord to pass through the electrical interface 10a and be electrically connected to the internal controller 40 to provide the power required by the controller 40.

[0048] In one embodiment, the transparent plate 20 is high-strength laminated glass. In this way, while ensuring that it does not affect personnel's observation of the inside of the tank B, it also has good compressive performance, avoiding the breakage of the transparent plate 20 during transportation.

[0049] Referring to Figure 3 , the present disclosure embodiment also provides a storage tank, including a tank B and the window device A of the above embodiment installed on the tank B.

[0050] For the storage tank according to the embodiment of the present disclosure, adopting the above window device A, the technical effects are the same as those of the above window device, which will not be elaborated here.

[0051] The working process of the present utility model is as follows:

[0052] External compressed air is introduced into the second chamber 70 so that the gas is stabilized in the second chamber 70. Then, the gas in the second chamber 70 is guided to the blowing nozzle 30 through the diversion air duct 90a formed between the diversion plates 90. Finally, the gas blows out from the blowing nozzle 30 along the horizontal direction of the transparent plate 20, so that a dynamic air curtain can be formed behind the transparent plate 20, which can prevent dust from adhering to the surface of the transparent plate 20 and ensure a clear line of sight in the area behind the transparent plate 20.

[0053] When a person approaches the observation port 10c for observation, the infrared detection member 50 detects a signal and transmits it to the controller 40. The controller 40 controls the lighting member 60 to turn on, which can illuminate the area of the observation port 10c to provide lighting in the dark and facilitate the person to observe the situation inside the storage tank; when the person moves away from the observation port 10c, the infrared detection member 50 does not detect a signal, and then the controller 40 controls the lighting member 60 to turn off, realizing the automatic on or off control of the lighting member 60.

[0054] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present utility model.
