Description

Technical Field

[0001] The invention relates to the technical field of centrifugal air compressors, in particular to an improved centrifugal air compressor for textile use. Background Art

[0002] The principle of centrifugal air compressor is that the impeller drives the gas to rotate at high speed, so that the gas generates centrifugal force. Due to the expansion pressure flow of the gas in the impeller, the flow rate and pressure of the gas after passing through the impeller are increased, and compressed air is continuously produced. It is usually used in weaving factories. There are multiple air jet looms in the loom workshop, and air compressors and peripheral equipment are installed in the compressor room. The air compressed by the air compressor is supplied to multiple main tanks and auxiliary tanks of the air jet loom through the air pipeline, and is used for the operation of the air jet loom.

[0003] For example, the patent with publication number CN219795706U discloses a centrifugal air compressor with an air intake filtering function, comprising: a device body, including an equipment body, one end of the equipment body is connected to a motor, the other end of the equipment body is connected to an air intake pipe, and one side of the air intake pipe is connected to an air outlet pipe; a filtering structure is embedded in the air intake pipe, including a first filter screen, one side of the first filter screen is connected to a connecting spring, the first filter screen and the second filter screen are used to perform layered filtration on dust and impurities mixed in the airflow, and the filter cotton between the first filter screen and the second filter screen performs secondary filtration on impurities that have not been filtered out by the first filter screen, thereby achieving a multi-layer filtration effect, avoiding dust and impurities mixed in the air from following the airflow into the centrifugal air compressor, causing dust and impurities to accumulate inside the centrifugal air compressor, affecting the normal use of the centrifugal air compressor. However, the existing centrifugal air compressor filter is more or less fixed, and is embedded at the air inlet port of the centrifugal air compressor. After long-term use, a large amount of dust is easily collected on its surface, causing mesh clogging, thereby affecting the air supply effect of the centrifugal air compressor. Therefore, it needs to be manually replaced and cleaned regularly, which is inconvenient to use.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The improved centrifugal air compressor for textile use proposed by the present invention has a motor driving an impeller to rotate at high speed in a volute through a transmission shaft, thereby creating negative pressure and continuously attracting external air into the volute from an air inlet. The impeller works on the gas to increase the gas pressure, thereby forming a high-pressure airflow that is led out from an air outlet pipe for use by textile equipment. During the air intake process, the impeller rotates to attract external airflow into the volute, thereby forming a stable and fast airflow in the air intake cylinder, which impacts the wind wheel to make it rotate. The wind wheel drives the first roller to rotate through a pulley, thereby driving the filter belt to move along the opening opened by the first roller and the second roller. The font rotates continuously, and the end of the filter belt close to the air inlet enters the installation cavity and touches the end cover, causing the dust on the surface to fall off. At the same time, the cleaning cotton in the installation cavity further cleans the filter belt to ensure its cleanliness, avoiding the traditional filter screen from clogging the mesh due to dust accumulation due to continuous fixed-point use, which affects the use effect of the air compressor. Moreover, after the air supply is completed, the guide plate can also scrape the outer wall of the filter belt in the air inlet when it is deflected and reset, which effectively solves the problem of easy clogging of the air intake filter of the traditional centrifugal air compressor and ensures the stable operation and efficient air supply of the centrifugal air compressor in textile production.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1 and Figure 2The invention discloses an improved centrifugal air compressor for textile use, which is mainly composed of important parts such as a base 1, a device body 2, a volute 3, an air outlet pipe 31, heat dissipation fins 23 and an air inlet cylinder 4. The top of the base 1 is fixedly connected with the device body 2, and the base 1 can fix the device body 2 inside a soundproof box for installation to ensure the silence of the device during operation. The outer wall of one end of the device body 2 is fixedly connected with a volute 3, and the outer wall of one side of the volute 3 is fixedly connected with an air outlet pipe 31. Heat dissipation fins 23 are evenly arranged on the side wall of the air outlet pipe 31 and on the top of the device body 2, respectively. A connected air inlet cylinder 4 is fixedly connected to the side wall at the end of the volute 3. After the air is taken in from the air inlet cylinder 4, it enters the volute 3 for centrifugal supercharging, so that the high-pressure airflow is led out from the air outlet pipe 31 for use by the textile equipment.

[0032] In order to solve the problem that the existing centrifugal air compressor filter is fixed and easy to be clogged by dust after long-term use, it needs to be replaced and cleaned regularly, which is troublesome. Figure 1-Figure 4 and Figure 7-Figure 8 , provide the following preferred technical solutions:

[0033] A motor 21 is fixedly connected to the outer wall of the device body 2 away from the volute 3, and a transmission shaft 22 is fixedly connected to the output end of the motor 21. The end of the transmission shaft 22 passes through the device body 2 and extends into the volute 3. The end of the transmission shaft 22 in the volute 3 is fixedly connected to the impeller 32. An end cover is provided at the end of the air inlet cylinder 4. The end cover is detachably connected to the outer wall at the port of the air inlet cylinder 4 by bolts. A square air inlet 41 is opened on the side wall at the middle of the end cover. A first mounting groove 42 is opened at the top of the inner cavity of the air inlet cylinder 4 inside the air inlet 41. First rollers 43 are movably arranged between the inner walls on both sides of the first installation groove 42 and between the inner walls on both sides of the inner cavity of the air inlet cylinder 4 above the air inlet port 41. The first installation grooves 42 are arranged horizontally and parallelly. A wind wheel 44 is movably arranged between the inner walls on both sides of the inner cavity of the air inlet cylinder 4 at the bottom port of the first installation groove 42. The wind wheel 44 is located at the junction of the first installation groove 42 and the inner cavity of the air inlet cylinder 4. Pulleys are respectively arranged on the outer walls of the wind wheel 44 and the shaft rod at the end of the first roller 43 in the first installation groove 42. A transmission belt is sleeved on the outer wall of the pulley. The transmission ratio between the pulleys is adjusted to realize the slow rotation control of the first roller 43, and an installation cavity 45 is arranged below the inner cavity of the air inlet cylinder 4, and a fixing plate 46 is fixedly connected to the side wall of the installation cavity 45 and the lower end of the top plate, respectively, and a second roller 47 is movably arranged between the side wall of the installation cavity 45 and the side wall of the fixing plate 46 at the lower end of the top plate, and a filter mesh belt 5 is sleeved in a mouth shape on the outer wall of the first roller 43 and the second roller 47, and the width of the filter mesh belt 5 is greater than the width of the air inlet 41, and the end of the filter mesh belt 5 close to the end cover is in contact with the end of the air inlet 41. The air inlet 41 is provided with an outer wall thereof, and the inner walls of the end covers on both sides of the air inlet 41 are respectively fixedly connected with clamping strips 6, the clamping strips 6 are arranged in contact with the outer wall of the filter mesh belt 5 on both sides of the air inlet 41, and guide plates 411 are movably arranged at even intervals between the inner walls on both sides of the air inlet 41, and the upper and lower adjacent guide plates 411 are linked by movable strips, and the inner wall at the top of the end cover is provided with an electric telescopic rod movably connected to the uppermost guide plate 411, and the electric telescopic rod controls the deflection opening of the guide plate 411 by telescopic adjustment (prior art).

[0034] Positioning rods 412 are fixedly connected to both ends of the guide plate 411, and positioning holes are respectively opened on the inner walls on both sides of the air inlet 41 corresponding to the guide plates 411. The ends of the positioning rods 412 extend through the positioning holes, and the outer walls of the positioning rods 412 in the positioning holes are fixedly connected to the first springs 413, and the outer ends of the first springs 413 are fixedly connected to the inner walls of the positioning holes; the positioning rods 412 on the outer walls at both ends of the guide plates 411 are both arranged above the horizontal center line of the guide plates 411. When the first springs 413 maintain a normal relaxed state, the guide plates 411 in the air inlet 41 are both fitted together at the upper and lower ends. At this time, the guide plates 411 completely block the air inlet 41, and when the guide plates 411 are tilted, their tilted lower ends are fitted together with the outer wall of the filter belt 5 at the air inlet 41.

[0035] A fixing rod is fixedly connected to the lower end of the top plate of the installation cavity 45, and a limiting baffle 451 is fixedly connected to the bottom of the fixing rod. The limiting baffle 451 is horizontally close to and suspended above the filter mesh belt 5 between the second rotating rollers 47. Cleaning cotton 452 is fixedly connected to the lower end of the top plate of the installation cavity 45 on one side of the limiting baffle 451. The cleaning cotton 452 is suspended and distributed on both sides of the filter mesh belt 5 on one side of the limiting baffle 451. The cleaning cotton 452 is used to wipe and clean the outer walls on both sides of the filter mesh belt 5.

[0036] The compression strip 6 includes a guide rod 61 fixedly connected to the inner walls of the end covers on both sides of the air inlet 41 and an L-shaped plate 62 movably inserted into the outer wall of the guide rod 61. The end of the guide rod 61 outside the L-shaped plate 62 is fixedly connected to a side plate, and an elastic component 63 is wrapped around the outer wall of the guide rod 61 between the side plate and the L-shaped plate 62, and a ball 64 is evenly and movably embedded on the outer wall of the end of the L-shaped plate 62 close to the air inlet 41. One end of the ball 64 extends to the outside of the L-shaped plate 62, and when the ball 64 is set in contact with the outer wall at the edge of the filter belt 5 on both sides of the air inlet 41, the elastic component 63 is in a compressed state.

[0037] Specifically, when the motor 21 drives the impeller 32 to rotate at a high speed in the volute 3 through the transmission shaft 22, negative pressure is created to continuously draw outside air from the air inlet 41 through the air inlet cylinder 4 into the volute 3. Due to the centrifugal force, the impeller 32 works on the gas to increase the gas pressure, and causes the gas in the volute 3 to form a high-pressure airflow that is continuously discharged from the outlet pipe 31 for use by the textile equipment. When the impeller 32 rotates to draw the outside airflow into the volute 3, a stable and fast airflow is formed in the air inlet cylinder 4. The airflow impacts the wind wheel 44 located at the lower part of the inner cavity of the air inlet cylinder 4 to rotate it. The wind wheel 44 drives the first roller 43 in the first mounting groove 42 to rotate by using a pulley, so that the first roller 43 drives the filter mesh belt 5 on its outer wall. The filter belt 5 continuously rotates along the U-shaped opening opened by the first roller 43 and the second roller 47, and the end of the filter belt 5 close to the air inlet 41 enters the installation cavity 45 from the inner cavity of the air inlet cylinder 4 and touches the side wall of the end cover. The dust attached to the surface of the filter belt 5 falls from the air inlet 41 through the rotational contact with the end cover, and at the same time, the cleaning cotton 452 in the installation cavity 45 is used to further clean the automatically rotating filter belt 5 to ensure the cleanliness of the filter belt 5 rotated to the air inlet 41, and to avoid the problem of dust adhesion and accumulation causing mesh clogging and affecting the use effect of the air compressor when the traditional filter is used continuously at a fixed point, and when the guide plate 411 is deflected and reset after the air supply is completed, the outer wall of the filter belt 5 in the air inlet 41 is scraped at the same time, which is convenient to use.

[0038] like Figure 3-Figure 6 As shown, in order to further ensure the cleanliness of the filter belt 5, thereby maintaining the efficient filtering and air supply effect of the air compressor, this embodiment provides the following technical solutions:

[0039] Both ends of the second roller 47 are fixedly connected with positioning shafts, which extend through and extend to the outside of the fixed plate 46. The end of the positioning shaft on the outside of the fixed plate 46 is fixedly connected with a toggle bar 471, and the end of the toggle bar 471 is movably connected with a first connecting rod 472 on the side wall, and the end of the first connecting rod 472 is movably connected with a fixing bar 473, and the bottom of the fixing bar 473 is fixedly connected with a mounting plate 474, which is suspended parallel to the filter belt 5 between the second rollers 47, and the top of the mounting plate 474 is fixedly connected with auxiliary cleaning parts 7 at uniform intervals, and dust discharge holes 453 are evenly spaced on the bottom plate of the mounting cavity 45 below the mounting plate 474.

[0040] The auxiliary cleaning part 7 includes an elastic air cushion 71 fixedly connected to the top of the mounting plate 474 at uniform intervals and a mounting head 72 fixedly connected to the top of the elastic air cushion 71, a second mounting groove 73 is provided on the top of the mounting head 72, a one-way air inlet nozzle 74 is provided on the bottom plate at the middle of the second mounting groove 73, and one-way air outlet nozzles 75 are evenly arranged on the bottom plate of the second mounting groove 73 outside the one-way air inlet nozzle 74, the one-way air inlet nozzle 74 and the one-way air outlet nozzle 75 are both connected to the elastic air cushion 71, and an interception net 76 is fixedly connected between the inner wall of the second mounting groove 73 at the top of the one-way air inlet nozzle 74 and the one-way air outlet nozzle 75, and the top of the interception net 76 is flush with the top port of the second mounting groove 73.

[0041] When the end of the toggle bar 471 is vertically located at the bottom of the second roller 47, the mounting plate 474 and the filter mesh belt 5 between the second roller 47 maintain the maximum parallel distance. At this time, the elastic air cushion 71 remains inflated and the top of the interception net 76 fits against the bottom of the filter mesh belt 5 between the second rollers 47.

[0042] Specifically, when the wind wheel 44 drives the first roller 43 to rotate, the first roller 43 drives the filter mesh belt 5 to rotate by cooperating with it, and the filter mesh belt 5 synchronously drives the remaining first rollers 43 and second rollers 47 to rotate, so that when the filter mesh belt 5 rotates in a square shape, the second roller 47 drives the toggle bar 471 to rotate by using the positioning shaft at the end, and the toggle bar 471 drives the first connecting rod 472 to rotate when rotating, so as to cooperate with the fixing bar 473 and the mounting plate 474 to squeeze the filter mesh belt 5 between the second rollers 47 up and down to squeeze the auxiliary cleaning part 7. When the mounting plate 474 moves up, it pushes the elastic air cushion 71 to squeeze the filter mesh belt 5 for compression, and the gas inside the elastic air cushion 71 is exhausted through the one-way After the nozzle 75 sprays out, it impacts the filter belt 5 through the intercepting net 76, so that the dust attached to the bottom of the filter belt 5 flies outward from the gap between the filter belt 5 and the intercepting net 76, and then falls into the dust discharge hole 453 on the bottom plate of the installation cavity 45 and is discharged. When the installation plate 474 moves downward, the elastic air cushion 71 is squeezed and automatically expands under the action of elastic deformation recovery, and is inflated by the one-way air inlet nozzle 74. When the one-way air inlet nozzle 74 inhales air, it provides suction to the bottom of the filter belt 5, and sucks off the dust firmly adhered to the bottom of the filter belt 5, thereby completing the super cleaning of the rotating filter belt 5, effectively ensuring the filtering and ventilation effect of the filter belt 5 at the air inlet 41, and is easy to use.

An arc-shaped opening 372 is provided on the outer wall of one side of the connecting part above the bottom plate of the positioning cylinder 371. The measuring mark rod 35 in the positioning cylinder 371 is movably sleeved with an indicating needle 373. The end of the indicating needle 373 passes through the arc-shaped opening 372 and extends to the outside of the positioning cylinder 371. The top of the fixed end of the indicating needle 373 is fixedly connected with a sleeve 374. The sleeve 374 is sleeved around the outside of the measuring mark rod 35. A second clockwork spring 375 is fixedly connected to the outer wall of the sleeve 374, the outer end of the second clockwork spring 375 is fixedly connected to the inner wall of the positioning tube 371, a limiting groove 376 is provided on the inner wall of one side of the sleeve 374, and a slider is fixedly connected to the corresponding limiting groove 376 on the outer wall of one side of the measuring benchmark 35. When the second clockwork spring 375 maintains a normal relaxation state, the indicating needle 373 is parallel to the transmission shaft 22, and the slider is located at the edge of the bottom port of the limiting groove 376.

[0046] Specifically, when the bearing rotor is worn, the transmission shaft 22 automatically deflects and tilts downward under the action of gravity. After the transmission shaft 22 tilts, the positioning ring 33 cooperates with the second connecting rod 34 to squeeze the measuring mark rod 35 downward. The lower end of the measuring mark rod 35 moves downward and pushes the protruding compression support spring 36, so that the lower end of the measuring mark rod 35 extends out of the volute 3, thereby displaying the degree of inclination of the bearing rotor of the transmission shaft 22 after wear according to the moving scale data. The bearing can be replaced in time according to the data feedback to avoid excessive damage to the transmission shaft 22 and surging during operation of the air compressor equipment. After the measuring mark rod 35 moves downward, the protrusion on its outer wall slides out of the bottom port of the upper limit slide groove 376 on the inner wall of the measuring mark rod 35, and the sleeve 374 restricts it. Therefore, under the action of the second spring spring 375, the indicator needle 373 automatically rotates 90 degrees in the arc-shaped opening 372, so that the end of the indicator needle 373 is suspended on one side of the volute 3, staggered with the intake pipe 4, and convenient for observing the indicator needle 373, which is simple and effective.
