Description

Technical Field

[0001] The present invention relates to the technical field of blowers, and more particularly to a high-performance large-mass gas circulation blower. Background Art

[0002] In scenarios such as the aeration tank of a sewage treatment plant, flue gas desulfurization in a thermal power plant, and blast furnace blowing in iron and steel smelting, it is necessary to continuously transport tens of thousands of cubic meters of gas per minute. Ordinary blowers are difficult to meet the requirements due to flow limitations. High-performance equipment can significantly improve the gas transportation efficiency by optimizing the impeller design and power system. For some processes (such as pneumatic conveying and fluidized bed reaction), it is necessary to simultaneously meet high pressure and large flow. The efficiency of traditional equipment drops sharply under high pressure, while high-performance blowers can maintain high energy efficiency in the high-pressure range through multi-stage compression or turbine technology. Although the initial investment of high-performance blowers is relatively large, they adopt technologies such as variable frequency control and magnetic levitation bearings, and the energy consumption is reduced by 30%-50% compared with traditional equipment. For industrial scenarios with an annual operation of more than 8000 hours, the cost savings brought by energy conservation far exceed the price difference of the equipment. Some high-performance blowers adopt explosion-proof sealing structures to ensure safe and stable operation. Traditional equipment is prone to failure due to material deformation, while some high-performance equipment can adapt to harsh conditions through high-temperature resistant coatings and strengthened structure designs.

[0003] When a high-performance large-mass gas circulation blower is working, it generally sucks in gas and pre-treats the inhaled air, and then compresses the air through the impeller. After compression, the air passes through the outlet. In some specific working conditions, the blower also needs to filter the compressed air again (for example, a filter plate is installed at the outlet of the blower in a ceramic factory to prevent clay dust from entering the downstream pipeline and prevent secondary pollution). Finally, the gas is discharged.

[0004] After the filter plate at the air outlet of the current high-performance large-mass gas circulation blower filters for a period of time, the filtering effect of the filter plate is greatly reduced, and it can no longer meet the filtering requirements. Even the filter screen may cause secondary pollution to the discharged air. However, most of the time, the filter screen cannot be automatically replaced when it is replaced, which may cause secondary pollution of the air due to the pollution of the filter screen. In addition, in some blower production activities, a fixed air volume may not be required, and the outlet air volume may need to be changed in some situations. Summary of the Invention

[0033] In this embodiment, it should be specifically noted that: the weight of the impurities accumulated on the air outlet filter plate 10 can cause a considerable deformation of the second spring 706, resulting in the operation of the device.

[0034] The main difference between this embodiment and the prior art is that in this embodiment, the air outlet filter plate 10 with ineffective filtering effect and changed weight is replaced by utilizing the initiative of the motor and the fluidity of the gas, specifically including the reversing strip 2, the pushing component 3, the transmission mechanism 7, the elastic abutting and clamping component 8, and the energy storage component 9;

[0035] The above structure is the main structure of this embodiment, which solves the problem that the current blower flow is difficult to adjust. The third motor 11 is an existing structure, and the specific structure and connection method of the third motor 11 are not described in detail in this embodiment.

[0036] Reference Figure 2 , Figure 3 and Figure 9 The blower body 1 includes an air outlet pipe 105, a dustproof shell 103 is provided above the air outlet pipe 105, a support shell 104 is fixedly connected below the air outlet pipe 105, the dustproof shell 103 includes an upper shell 1031, an upper stopper 1032 and a lower stopper 1033 are respectively fixed above and below the inner wall of the dustproof shell 103 close to the impeller 6, an upper moving groove 1034 is provided on the upper inner wall of the upper shell 1031, and the length of the upper moving groove 1034 extends to the upper stopper 1032, and a displacement sensor 1035 is provided on the inner side wall of the upper shell 1031 close to the impeller 6 A lower movable groove 1051 is provided on the top of the upper wall of the air outlet pipe 105, and the length of the lower movable groove 1051 extends through the lower stopper 1033. A clearance groove 1052 is provided inside the air outlet pipe 105, and the opening and closing component 5 is located in the clearance groove 1052. An air volume adjustment groove 1053 is provided at the outlet of the air outlet pipe 105. An upper through-hole 1054 is penetrated through the upper wall of the air outlet pipe 105, and the upper through-hole 1054 is penetrated with the air volume adjustment groove 1053. A lower through-hole 1055 is penetrated through the lower wall of the air outlet pipe 105, and the lower through-hole 1055 is located at the bottom of the upper through-hole 1054.

[0037] In this embodiment, it should be specifically explained that: when the filtering effect of the air outlet filter plate 10 fails and falls into the inside of the receiving barrel 709, the spare air outlet filter plate 10 will fall to the top of the sliding sealing plate 704 through the upper through hole 1054 and the lower through hole 1055.

[0038] Reference Figure 3 The push assembly 3 includes a first motor 301, a screw 302 is fixedly connected to the rotating shaft of the first motor 301, a sliding block 304 is connected to the screw 302, the sliding block 304 is slidably connected to the upper moving groove 1034 and the lower moving groove 1051, and a first bracket 303 is rotatably connected between the screw 302 and the upper moving groove 1034 and the lower moving groove 1051.

[0039] In this embodiment, it should be specifically explained that: the sliding blocks 304 in four directions are started, driving the screw 302 to rotate, and the sliding blocks 304 move toward the direction close to the third motor 11, and the sliding blocks 304 in four directions squeeze multiple spare air outlet filter plates 10 and move slowly forward.

[0040] Reference Figure 4, The opening adjustment component 4 includes a placement box 401. The placement box 401 is box-shaped with an opening. The opening of the placement box 401 faces the air volume adjustment groove 1053. A sliding block 403 is slidably connected inside the placement box 401, and an oil cylinder 402 is connected between the sliding block 403 and the placement box 401.

[0041] In this embodiment, it should be specifically noted that: if it is necessary to change the flow rate discharged by the blower, start the oil cylinder 402. The oil cylinder 402 pushes the sliding block 403 to extend into the air outlet pipe 105 through the air volume adjustment groove 1053. The amount by which the sliding block 403 extends out of the air outlet pipe 105 can be adjusted, thereby changing the flow rate discharged by the blower.

[0042] Refer to Figure 5 , The reversing bar 2 includes a guiding portion 201. One end of the guiding portion 201 is fixedly connected to one end of a rack portion 202. The upper part of the other end of the rack portion 202 is connected to a lifting portion 203. The upper part of the lifting portion 203 is connected by a turning to a transverse portion 204. The transverse portion 204 is perpendicular to the guiding portion 201. The other end of the transverse portion 204 is connected to a pushing portion 205. The pushing portion 205 is parallel to the guiding portion 201. The rack portion 202 meshes with the energy storage component 9. The pushing portion 205 and the cross block 7011 are located in the same vertical plane. A first support guiding rod 206 is provided between the guiding portion 201 and the bottom wall of the support shell 104. The first support guiding rod 206 is slidably connected to the guiding portion 201. A second support guiding rod 207 is provided between the pushing portion 205 and the opening box 701. The second support guiding rod 207 is slidably connected to the pushing portion 205.

[0043] In this embodiment, it should be specifically noted that: the length of the rack portion 202 is sufficient for the pushing portion 205 to complete the corresponding actions.

[0044] Refer to Figure 3 and Figure 7 , The energy storage component 9 includes a rotating rod 902. Two second driving wheels 901 are key-connected to both sides of the rotating rod 902. A power storage gear 903 is provided between the second driving wheels 901. The power storage gear 903 is coaxial with the rotating rod 902. A scroll spring 904 is connected between the rotating rod 902 and the power storage gear 903. The two ends of the second driving wheel 901 are rotatably connected to a second bracket 905. The bottom of the second bracket 905 is fixedly connected to the bottom inner wall of the support shell 104.

[0045] In this embodiment, it is necessary to specifically explain that: the second rack 7013 descends and drives the second driving wheel 901 meshed with it to rotate, and the rotating rod 902 also rotates. The power storage gear 903 does not rotate under the obstruction of the clamping portion 804, but the volute spring 904 elastically contracts under the rotation of the rotating rod 902. When the elastic clamping assembly 8 releases the fixation of the power storage gear 903, the power storage gear 903 rotates under the elastic restoring force of the volute spring 904, and the power storage gear 903 drives the rack portion 202 meshed with it to rotate. The second rack 7013 also rises, driving the second driving wheel 901 and the rotating rod 902 to rotate in the opposite direction. The rotation of the rotating rod 902 causes the power storage gear 903 to rotate in the opposite direction through the volute spring 904. The reverse rotation of the second driving wheel 901 causes the reversing bar 2 to return to its original position. The sliding sealing plate 704 returns to its original position under the elastic restoring force of the first spring 703, blocking the first through hole 705. In the process of the inclined block 7014 returning to its original position, the suppression of the elastic blocking assembly 8 disappears, and the elastic blocking assembly 8 returns to its original position to clamp the power storage gear 903.

[0046] Reference Figure 8 The elastic card assembly 8 includes a vertical round rod 802, the middle protrusion of the vertical round rod 802 is connected to an extrusion block 803, the top of the vertical round rod 802 is fixedly connected to a card part 804, the head of the card part 804 is pointed, and a support tube 801 is provided at the bottom of the vertical round rod 802. The support tube 801 is an open tube, and a third spring 805 is provided between the support tube 801 and the extrusion block 803.

[0047] In this embodiment, it should be specifically explained that: when the inclined block 7014 descends, the inclined block 7014 compresses the third spring 805 through the extrusion block 803 to shrink the locking portion 804 and descend, and the locking portion 804 releases the fixation of the power storage gear 903. In the process of the inclined block 7014 returning to its original position, the pressure on the extrusion block 803 disappears, and the locking portion 804 rises and returns to its original position under the rebound action of the third spring 805 to clamp the power storage gear 903.

[0048] Reference Figure 9 The opening and closing component 5 includes a second motor 501, which is meshedly connected to a first driving wheel 502, one side of the first driving wheel 502 is meshedly connected to a first rack 503, a movable baffle 504 is fixedly connected to the top of the first rack 503, the movable baffle 504 is slidably connected to the clearance groove 1052, and a guide plate 505 is movably connected to the back side of the first rack 503, and the guide plate 505 is fixedly connected to the clearance groove 1052.

[0049] In this embodiment, it should be specifically explained that: the first driving wheel 502 moves the first rack 503 and the movable baffle 504 back and forth under the action of the forward and reverse rotation of the second motor 501, so that the upper through-hole 1054 is opened or closed.

[0050] Working principle of the present invention:

[0051] The main problem solved in this embodiment is as follows: by utilizing the initiative of the motor and the fluidity of the gas, the air outlet filter plate 10 with ineffective filtering effect and changed weight is replaced, and by utilizing the continuity of the gas, the size of the outlet of the blower is adjusted, thereby changing the air volume, and solving the problem that the flow rate of the current blower is not easy to adjust.

[0052] The specific steps are as follows:

[0053] The third motor 11 is started, the impeller 6 rotates, compresses the air that enters the inside of the air inlet filter plate 106 after being filtered by the air inlet filter plate 106, the compressed air passes through the air outlet pipe 105, and after being filtered by the air outlet filter plate 10, it is discharged through the outlet of the air outlet pipe 105. If it is necessary to change the flow rate discharged by the blower, the oil cylinder 402 is started, and the oil cylinder 402 pushes the sliding block 403 to extend into the air outlet pipe 105 through the air volume adjustment groove 1053. The amount by which the sliding block 403 extends out of the air outlet pipe 105 can be adjusted, thereby changing the flow rate discharged by the blower;

[0054] When the air outlet filter plate 10 continuously filters impurities, the impurities continuously adhere to the air outlet filter plate 10, the weight of the air outlet filter plate 10 continuously increases, and the air outlet filter plate 10 compresses the opening box 701 through the first spring 703 supported below the air outlet filter plate 10. The opening box 701 compresses the second spring 706 and undergoes a compressive deformation and descends. The avoidance guide groove 7012, the sliding sealing plate 704, the air outlet filter plate 10, and the cross block 7011 descend. The second rack 7013 and the inclined block 7014 also descend accordingly. The second rack 7013 drives the second driving wheel 901 engaged with it to rotate, and the rotating rod 902 also rotates. The energy storage gear 903 does not rotate under the blockage of the blocking portion 804, but the scroll spring 904 elastically contracts under the rotation of the rotating rod 902. When the weight of the air outlet filter plate 10 increases to a certain extent, during this process, the filtering effect of the air outlet filter plate 10 is greatly reduced and cannot meet the filtering requirements. During this process, the cross block 7011 descends to the same height as the pushing portion 205. The descent of the inclined block 7014 compresses the third spring 805 through the extrusion block 803 and the blocking portion 804 descends. The blocking portion 804 releases the fixation of the energy storage gear 903. At this time, under the elastic restoring force of the scroll spring 904, the energy storage gear 903 rotates. The energy storage gear 903 drives the rack portion 202 engaged with it to move, and the pushing portion 205 also moves accordingly. The pushing portion 205 pushes the sliding sealing plate 704 through the cross block 7011. The sliding sealing plate 704 compresses the first spring 703 until the first through hole 705 is completely opened. The air outlet filter plate 10 falls from the first through hole 705 through the second through hole 708 to the bottom of the material receiving cylinder 709. The force on the opening box 701 disappears, and under the rebounding action of the second spring 706, the opening box 701 rises to restore its original position. The second rack 7013 and the inclined block 7014 also rise, driving the second driving wheel 901 and the rotating rod 902 to rotate reversely. The rotation of the rotating rod 902 causes the energy storage gear 903 to rotate reversely through the scroll spring 904. The reverse rotation of the second driving wheel 901 causes the reversing strip 2 to restore its original position. The sliding sealing plate 704 restores its original position under the elastic restoring force of the first spring 703 and blocks the first through hole 705. During the process of the inclined block 7014 restoring its original position, the pressing on the extrusion block 803 disappears, and the blocking portion 804 rises to restore its original position under the rebounding action of the third spring 805 and blocks the energy storage gear 903;

[0055] Subsequently, the second motor 501 starts to drive the first driving wheel 502 to rotate. The first driving wheel 502 drives the first rack 503 engaged with it to move. The first rack 503 drives the moving baffle 504 to move away from the impeller 6, and the upper through opening 1054 is opened. The second motor 501 stops rotating. The spare air outlet filter plate 10 falls from the upper through opening 1054 and the lower through opening 1055 to the top of the sliding sealing plate 704 under the action of gravity, pressing the sliding sealing plate 704 and the opening box 701 to descend;

[0056] Subsequently, the displacement sensor 1035 senses that the spare air outlet filter plate 10 has reached the working position, and the second motor 501 rotates reversely, driving the movable baffle 504 to return to its original position, and the upper through port 1054 is closed. At this time, the sliding blocks 304 in four directions are activated, driving the screw 302 to rotate, and the sliding blocks 304 move towards the direction close to the third motor 11. The sliding blocks 304 in four directions squeeze the multiple spare air outlet filter plates 10 to move forward slowly until the displacement sensor 1035 senses that the spare air outlet filter plate 10 closest to the third motor 11 falls from the upper surface of the top plate of the air outlet pipe 105 above the movable baffle 504, and the first motor 301 stops rotating and the sliding blocks 304 also stop moving.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
