[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the embodiments of the specification.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0040] Example 1

[0041] Reference Figure 1 to Figure 2 , is the first embodiment of the present invention, which provides an indoor air blast dust removal device, including an air blast dust removal device 100, the air blast dust removal device 100 includes a pipeline 101, a dust collector 102 and an exhaust fan 103, the air intake port of the exhaust fan 103 is connected to the dust collector 102 through a flange, and the exhaust port of the exhaust fan 103 is connected to the pipeline 101 through a flange, and the dust collector 102 and the exhaust fan 103 are supported and fixed by a bracket platform 104. The dust collector 102 of this embodiment adopts a bag dust collector, and the exhaust fan 103 adopts an axial flow fan. The axial flow fan is arranged longitudinally, the bag dust collector is located directly below the axial flow fan, and the pipeline 101 is installed above the axial flow fan, and the other end of the pipeline 101 extends into the room.

[0042] Through the structural setting of the device of the present invention, it is suitable for closed areas such as fan rooms, TRTs, and electromagnetic stations. The indoor positive pressure dust removal technology is applied. The exhaust fan 103 works to keep the indoor air at a positive pressure, thereby preventing outdoor dust from entering the room. After the outdoor air is processed by the dust collector 102, it is continuously transported to the room, so that the indoor air maintains a positive pressure state, improves the working environment of the machine room, reduces the failure rate of equipment, and plays a role in dust reduction, temperature reduction, and noise reduction.

[0043] It should be noted that the detector 200 for detecting the dust concentration in the duct 101 is also included. Through real-time monitoring by the detector 200, it can be determined whether the dust collector 102 needs to be cleaned. If cleaning is required, it can be back-blown and cleaned through the back-blowing device conventionally provided in the bag dust collector to ensure the indoor air quality; the detector 200 is installed near the exhaust fan 103 and can detect feedback data in the first time. The detector 200 of this embodiment adopts the S400-JD electrostatic dust concentration detector, which can detect dust particle sizes ranging from nominally 0.1μM to 200μM.

[0044] The detector 200 is installed outdoors. In order to provide a stable working environment for the detector 200 and prevent it from being accidentally disassembled during the operation of the entire device, the detector 200 of the present invention is connected to the pipeline 101 through the air control component 300. The air control component 300 of this embodiment can be a gas pressure control device such as a cylinder. When the cylinder is filled with gas, the cylinder piston rod extends to press and fix the detector 200. The air source of the air control component 300 is provided by the blower 102 of the air blowing dust removal device 100. When the entire device is in operation, the blower 200 is always working, and the air source inlet P1 of the air control component 300 is continuously filled with gas. At this time, the detector 200 can always be kept in a fixed state. When the blower 200 stops running, the air control component 300 also stops working at this time, and it is possible to disassemble, repair or replace the detector 200.

[0045] It should be noted that the pipe 101 at the exhaust port of the exhaust fan 103 is connected to the gas source inlet P1 through the connecting pipe 101a, and the connecting pipe 101a is installed on the side wall of the pipe 101 through a connector. The diameter of the connecting pipe 101a is larger than the diameter of the gas source inlet P1. Preferably, the connecting pipe 101a is in a shape of gradually shrinking diameter, and the smallest diameter end is connected to the gas source inlet P1, which has the effect of gathering and pressurizing the gas, thereby increasing the pressure of the gas entering the gas control component 300. The gas pressure can make the gas control component 300 work smoothly. Since the size of the detector 200 of this embodiment is small, the output power of the gas control component 300 does not need to be very large to meet the fixed requirements, and the axial flow fan is large in size and high in power, which can fully meet the needs of the gas control component 300; of course, those skilled in the art can also use a boosting device, such as a boosting pump, a boosting valve, etc., installed between the connecting pipe 101a and the gas source inlet P1 to further increase the gas pressure entering the gas control component 300, which is also within the protection scope of our invention. It only needs to meet the following requirements: when the exhaust fan 103 is working, the gas control component 300 is working at the same time; when the exhaust fan 103 stops running, the gas control component 300 stops running at the same time.

[0046] Example 2

[0047] Reference Figure 2 , Figure 3 , Figure 5 , which is the second embodiment of the present invention. The difference between this embodiment and the above embodiments is that the air control component 300 includes a cylinder body 301 connected to the pipeline 101, a piston 302 arranged in the cylinder body 301, and a control rod 303 connected to the piston 302. The piston 302 divides the cylinder body 301 into an air control chamber N1 and a reset chamber N2. The air source inlet P1 is connected to the air control chamber N1, and the reset chamber N2 is provided with an exhaust port P2. When the air control chamber N1 is filled with gas, the piston 302 moves in the direction of compressing the reset chamber N2, and the gas in the reset chamber N2 is discharged from the exhaust port P2. The piston 302 drives the control rod 303 to move linearly. When the control rod 303 contacts the detector 200, it is fixed.

[0048] In this embodiment, the control rod 303 and the detector 200 are locked together. When the control rod 303 approaches the detector 200, it is gradually locked to achieve the purpose of fixing. When the control rod 303 moves away from the detector 200, it is unlocked to achieve the purpose of disassembly.

[0049] Specifically, the detector 200 includes a columnar body 201, and the electronic components of the detector 200 are located in the columnar body 201. The columnar body 201 is detachably connected to the side wall of the pipe 101 through a thread S1, that is, the installation or disassembly of the detector 200 is achieved by rotating the columnar body 201. Therefore, the so-called locking in this embodiment, that is, locking the rotation of the columnar body 201, the columnar body 201 cannot rotate, and the detector 200 as a whole cannot be disassembled.

[0050] It should be noted that if Figure 3 As shown, a stop protrusion 202 is provided on the circumference of the columnar body 201, and a locking piece 303a is provided on the control rod 303. When gas is filled into the air control chamber N1, the control rod 303 drives the locking piece 303a to gradually approach the stop protrusion 202 until the locking piece 303a contacts the stop protrusion 202 in the circumferential direction. When the columnar body 201 drives the stop protrusion 202 to rotate, the stop protrusion 202 cannot continue to rotate due to the blocking effect of the locking piece 303a, and the control rod 303 and the detector 200 are locked.

[0051] Among them, a reset spring 304 connected to the piston 302 is provided in the reset chamber N2. When gas is filled into the air control chamber N1, the piston 302 compresses the reset spring 304 to move. When the exhaust fan 103 stops running, the reset spring 304 drives the piston 302 to reset, and the control rod 303 drives the locking piece 303a to move away from the stop protrusion 202, thereby realizing unlocking and separation from the detector 200.

[0052] Example 3

[0053] Reference Figures 3 to 5 , which is the third embodiment of the present invention. The difference between this embodiment and the above embodiments is that two locking members 303a are provided along the circumference of the detector 200, and the circumferential sides of the stop protrusion 202 can contact with two adjacent locking members 303a.

[0054] As shown in the above-mentioned embodiment 2, when there is only one locking member 303a, the stop protrusion 202 can rotate freely outside the circumferential width range of the locking member 303a, and the locking purpose can only be achieved when the stop protrusion 202 contacts the locking member 303.

[0055] Therefore, on this basis, this embodiment 3 is as follows. Figure 4 As shown, two locking members 303a are provided. When the locking members 303a move toward the stop protrusion 202, the stop protrusion 202 is located between the two locking members 303a. The rotation range of the stop protrusion 202 is limited to the space between the two locking members 303a, which greatly reduces the rotation range of the entire detector 200.

[0056] Example 4

[0057] Reference Figure 5 to Figure 6 , which is the fourth embodiment of the present invention. The difference between this embodiment and the above embodiments is that the locking members 303a are evenly distributed along the circumference of the detector 200, and the shape between two adjacent locking members 303a is complementary to the shape of the stop protrusion 202.

[0058] On the one hand, when the locking piece 303a moves toward the stop protrusion 202, the stop protrusion 202 can randomly enter the space between any two adjacent locking pieces 303a. Since the columnar body 201 is installed by threaded rotation, the position of the stop protrusion 202 may not be fixed. This arrangement can increase the fault tolerance and facilitate installation and operation. On the other hand, when the stop protrusion 202 enters the space between two adjacent locking pieces 303a, both sides of the stop protrusion 202 are in contact with the two adjacent locking pieces 303a at the same time, and the stop protrusion 202 has no rotation space, so the locking effect is better.

[0059] It should be noted that a control plug 303b is provided on the control rod 303, and a center hole 303b-1 is opened at the axis of the control plug 303b. The control plug 303b is sleeved on the outside of the detector 200 through the center hole 303b-1, and the locking piece 303a is evenly distributed along the inner wall of the center hole 303b-1 of the control plug 303b.

[0060] Example 5

[0061] Reference Figures 5 to 7, which is the fifth embodiment of the present invention. The difference between this embodiment and the above embodiments is that the detector 200 penetrates the cylinder 301 along the axial direction, the detection end 204 of the detector 200 is located outside the end cover 301a of the cylinder 301, and the connection terminal 205 of the detector 200 is located outside the end cover 301b of the cylinder 301.

[0062] The stopper protrusion 202 extends to the outside of the end cover 301a, and the control rod 303 extends from the air control chamber N1 to the outside of the end cover 301a and is connected to the control plug 303b; wherein, there are several control rods 303 distributed along the axial direction of the cylinder body 301, and there is a gap between two adjacent control rods 303, and the control rods 303 all penetrate the end cover 301a. At this time, the control rod 303 and the control plug 303b are restricted by the end cover 301a and cannot rotate, that is, the columnar body 201 cannot drive the control plug 303b to rotate, and the columnar body 201 cannot be forcibly rotated for disassembly, and the fixation is more reliable. wherein, the gap between the control rod 303 and the end cover 301a is filled with rubber to ensure the air tightness in the air control chamber N1.

[0063] It should be noted that, in order to ensure the airtightness of the entire device, an auxiliary cylinder 305 is provided on the outside of the control plug 303b, and the auxiliary cylinder 305 completely wraps the control plug 303b, the locking member 303a, and the stop protrusion 202. One end of the auxiliary cylinder 305 is fixed to the end cover 301a by means of thread, welding, or integral molding, and the other end of the auxiliary cylinder 305 is provided with a base 305a, and the control plug 303b is restricted to move between the base 305a and the end cover 301a. The axis of the base 305a is provided with a threaded hole P4, and the columnar body 201 is threadedly connected to the threaded hole P4; wherein, a mounting seat 306 is also provided on the outside of the cylinder body 301, and the cylinder body 301 is welded or threadedly fastened to the outside of the pipe 101 through the mounting seat 306, and the auxiliary cylinder 305 is fixed to the pipe 101 through the mounting seat 306, so as to achieve the purpose of detachable connection between the columnar body 201 and the pipe 101 through the thread.

[0064] Example 6

[0065] Reference Figures 7 to 10 , which is the sixth embodiment of the present invention. The difference between this embodiment and the above embodiments lies in that the locking piece 303a is in the shape of a straight tooth, that is, the overall shape is similar to an internal gear. The detector 200 is also provided with a spring bead 203 located between two adjacent locking pieces 303a. During the rotation of the columnar body 201, the spring bead 203 jumps from between the two locking pieces 303a to between the other two locking pieces 303a, which can realize the fixed-angle rotation of the columnar body 201, thereby realizing the fixed-angle movement of the stop protrusion 202, and can always maintain the relative position relationship between the stop protrusion 202 and the two adjacent locking pieces 303a, so that the locking cooperation and unlocking and separation actions are carried out smoothly.

[0066] Among them, the spring bead 203 can adopt a common structure with a bouncing function in the prior art. For example, the specific structure can include a round bead part 203a and a spring part 203b. The columnar body 201 is radially provided with an installation cavity. The spring part 203b located in the installation cavity is connected to the round bead part 203a. The pre-tightening force of the spring part 203b causes the end of the round bead part 203a smaller than the diameter to extend to the outside of the installation cavity.

[0067] In this embodiment, the spring bead 203 is located at the front end of the stop protrusion 202. When installing, the spring bead 203 first enters the central hole 303b-1 of the control plug 303b. When the columnar body 201 rotates and is threadedly connected with the base 305a, the spring bead 203 realizes the fixed angle rotation of the columnar body 201 under the action of the locking member 303a, ensuring that the stop protrusion 202 on the columnar body 201 moves along the circumferential direction at the same angle, so that the position of the stop protrusion 202 and the space between two adjacent locking members 303a always corresponds. In this way, the stop protrusion 202 can be evenly distributed along the circumference of the columnar body 201; further, in order to facilitate manufacturing, the stop protrusion 202 can be a gear sleeved on the outside of the columnar body 201, which can mesh with the locking member 303a in the shape of an internal gear.

[0068] In order to facilitate the installation of the detector 200, a hollow auxiliary cylinder 307 is also provided in the cylinder body 301. The auxiliary cylinder 307 and the cylinder body 301 form a hollow annular tube. The auxiliary cylinder 307 is formed integrally with the cylinder body 301 through the end cover 301a. The auxiliary cylinder 307 and the cylinder body 301 are located at the end cover 301b and are open. The end cover 301b is installed at the opening. It can be detachably installed by threads or fixedly installed by welding. The end cover 301b is provided with a through hole P5 matching the inner cavity of the auxiliary cylinder 307. The piston 302 and the reset spring 304 are located in the annular space between the cylinder body 301 and the auxiliary cylinder 307. The piston 302 divides the annular space into the air control chamber N1 and the reset chamber N2; the control rod 303 extends into the auxiliary cylinder 305 through the through hole P3 provided on the end cover 301a. The inner diameter of the auxiliary cylinder 307 can meet the requirements of the columnar body 201 and the stop protrusion 202 to enter and exit.

[0069] In this embodiment, the detection end 204 of the detector 200 is cylindrical, and its diameter is smaller than the diameter of the columnar body 201. A columnar transition portion 206 is arranged between the detection end 204 and the columnar body 201, and the diameter of the transition portion 206 is between the two; a thread is provided on the transition portion 206 for installation, and at the same time, the stop protrusion 202 and the spring bead 203 are both arranged at the transition portion 206, wherein the protrusion height of the stop protrusion 202 is not greater than the outer diameter of the columnar body 201, and the columnar body 201 cooperates with the inner diameter of the auxiliary cylinder 307, so that the columnar body 201 can move axially and rotate circumferentially in the auxiliary cylinder 307.

[0070] It should be noted that the space between the piston 302 and the end cover 301a is the air control chamber N1, and the space between the piston 302 and the end cover 301b is the reset chamber N2. In the initial state, the reset spring 304 moves the control plug 303b away from the end cover 301a. When the air control chamber N1 is filled with gas, the control plug 303b moves toward the end cover 301a, passing the spring ball 203 and moving toward the position of the stop protrusion 202.

[0071] It should be further explained that the control plug 303b has a certain axial length, which can ensure that when the control rod 303 is locked or unlocked with the detector 200, the spring bead 203 is always located in the center hole 303b-1 of the control plug 303b, that is, no matter when locked or unlocked, the circumferential position is always limited by the spring bead 203.

[0072] Specifically, when installing the air control component 300 , a mounting hole is pre-opened on the side wall of the pipeline 101 , the auxiliary cylinder 305 of the air control component 300 is first inserted into the mounting hole, and then the entire air control component 300 is threadedly fastened to the outside of the pipeline 101 through the mounting seat 306 .

[0073] When installing the detector 200, the detection end 204 of the detector 200 is extended into the auxiliary cylinder 307 from the through hole P5 of the end cover 301b. After the detection end 204 passes over the control plug 303b, the spring ball 203 first enters the central hole 303b-1 of the control plug 303b, and then the thread S1 of the transition part 206 contacts the threaded hole P4 of the base 305a. At this time, the spring ball 203 cannot move further due to the obstruction of the thread S1.

[0074] The detector 200 is rotated to make the thread S1 enter the threaded hole P4. During the rotation, the spring ball 203 bounces from between two locking pieces 303a to between another two locking pieces 303a, and the rotation of the detector 200 is controlled at a fixed angle until the thread of the detector 200 is locked.

[0075] Start the dust removal device 100, and the blower 102 fills gas into the air control chamber N1 through the connecting pipe 101a and the air source inlet P1. The air pressure pushes the piston 302 to move into the reset chamber N2 to compress the reset spring 304, and the control plug 303b moves along the spring ball 203 toward the position of the stop protrusion 202 until the locking piece 303a in the center hole 303b-1 of the control plug 303b is in circumferential contact with the stop protrusion 202. At this time, it is in a locked fit state, and the detector 200 cannot be forcibly rotated for disassembly.

[0076] When maintenance is required, the air blowing dust removal device 100 stops running, and the reset spring 304 in the reset chamber N2 pushes the moving piston 302 to reset until the locking member 303a is separated from the stop protrusion 202. At this time, the detector 200 can be rotated in the opposite direction for disassembly.

[0077] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), installation arrangement, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application.
