Description

Technical Field

[0001] The invention belongs to the technical field of rice processing, and in particular relates to a dust centralized settling device and method for rice fine processing. Background Art

[0002] The dust centralized sedimentation device is a device specially designed to collect and treat dust during rice processing. During the rice processing process, such as cleaning, husking, and milling, a large amount of dust will be generated. This dust will not only pollute the environment and affect the quality of rice, but may also pose a threat to the health of workers.

[0003] Most of the existing rice processing sedimentation devices adopt dry dust reduction and spray dust reduction in two ways when in use. In the spray centralized sedimentation process, in order to reduce production cost and maintenance difficulty, the spray dust reduction generally uses a traditional pressure type nozzle, which is mainly composed of a spray hole and a simple water flow channel, so that water is sprayed from the spray hole to a fixed direction under pressure. Since the area space inside the dust reduction box is large, if the spray device can only spray in one direction, then the water mist can only cover the area in this direction and its vicinity, and the area far away from the spray direction is difficult to be affected by the water mist, so that the dust in the corner area cannot contact with the water mist, thereby reducing the dust capture rate, resulting in the dust cannot be effectively settled, resulting in a decrease in the sedimentation efficiency of the entire device. Therefore, a dust centralized sedimentation device and method for rice processing are proposed to solve the problems raised in the background technology. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0034] like Figures 1 to 8 As shown, the present invention provides a dust centralized sedimentation device for rice finishing, comprising a dust reduction chamber 1, a water supply component 2 is arranged on one side of the dust reduction chamber 1, a first motor 3 is fixedly connected inside the water supply component 2, a swing component 4, a water delivery pipe 5 and a scraping component 9 are movably connected inside the dust reduction chamber 1, a plurality of nozzles 6 are arranged at the bottom end of the water delivery pipe 5, a second motor 7 is fixedly connected to one side of the top of the dust reduction chamber 1, a moving component 8 is movably connected to the top of the dust reduction chamber 1, a water outlet 10 is provided at the bottom end of the dust reduction chamber 1 near the second motor 7, and an air inlet pipe 11 is fixedly connected to one side of the dust reduction chamber 1;

[0035] The swing assembly 4 includes a rotating drum 41, an arc groove 42 is formed on the inner wall of the rotating drum 41, a round rod 43 is movably connected inside the arc groove 42, a tooth plate 44 is fixedly connected to the end of the round rod 43 away from the first motor 3, and a gear 45 is fixedly connected to the end of the water pipe 5 close to the first motor 3;

[0036] The moving assembly 8 includes a rotating rod 81, a guide groove 82 is formed on the surface of the rotating rod 81, and a slider 83 is movably sleeved outside the guide groove 82;

[0037] The scraping assembly 9 includes a scraper 91 , and the interior of the dust removal chamber 1 is symmetrically and movably connected with two limit blocks 93 .

[0038] The above scheme is adopted: through the design of the water supply component 2, it is convenient to transport clean water to the inside of the water pipe 5 and the nozzle 6, and then spray the dust air inside the dust reduction chamber 1. Through the opening of the arc groove 42, the rotating drum 41 can drive the round rod 43 and the gear 45 to move back and forth when rotating, and mesh with the gear 45 through the tooth plate 44, so that the gear 45 drives the water pipe 5 and several nozzles 6 at its bottom to swing left and right. The nozzle 6 swings to change the spray direction of the water mist, so that the water mist covers a larger space range in the dust reduction chamber 1, thereby increasing the probability of capturing dust inside the dust reduction chamber 1.

[0039] like Figure 1 , Figures 3 to 5 As shown, the water delivery assembly 2 includes a water tank 21, a water pump 22 is fixedly connected to the top of the water tank 21, the output end of the water pump 22 is fixedly connected to a water delivery pipe 23 connected to the water delivery pipe 5, the top of the water delivery pipe 23 is movably clamped in the inside of the water delivery pipe 5, the output shaft end of the first motor 3 is fixedly connected to the rotating drum 41, the arc groove 42 is corrugated, and the end of the round rod 43 away from the tooth plate 44 is fixedly connected with a protrusion, the protrusion is movably connected to the inside of the arc groove 42, the tooth plate 44 is meshed with the gear 45, and an atomizer is arranged inside the nozzle 6, and the top of the nozzle 6 is connected to the water delivery pipe 5.

[0040] The above scheme is adopted: an atomizer is arranged inside the nozzle 6, and its function is that the atomizer can break water into tiny droplets. During the spraying and dust reduction process, the tiny droplets have a larger specific surface area than ordinary water droplets, thereby greatly increasing the chance of the droplets contacting the dust particles. When the droplets contact the dust particles, they can more effectively adsorb the dust, causing the dust particles to agglomerate with each other and increase in weight, thereby settling faster under the action of gravity.

[0041] like Figures 2 to 3 , Figures 6 to 8As shown, the output shaft end of the second motor 7 is fixedly connected to the rotating rod 81, the guide groove 82 is composed of a transverse groove and an inclined groove with an arc of 360 degrees, the two ends of the transverse groove are respectively connected to the two ends of the inclined groove, the middle of the slider 83 is fixedly connected to a connecting column 84, the connecting column 84 is movably connected to the inside of the guide groove 82, one side of the slider 83 is fixedly connected to two springs 85, the slider 83 is elastically connected to the dust reduction chamber 1 through the springs 85, the opposite ends of the two limit blocks 93 are both movable inside the slider 83, and the top of the limit block 93 is fixedly connected There is a spring 86, and the limit block 93 is elastically connected to the slider 83 through the spring 86. A round block is set at the end of the limit block 93 away from the spring 86. Both sides of the inner wall of the dust removal chamber 1 are provided with slide grooves 94, and the slide groove 94 is trapezoidal. The round block on the limit block 93 is movably connected to the inside of the slide groove 94. The bottom end of the scraper 91 is inclined, and the two ends of the top of the scraper 91 are fixedly connected with support rods 92. The top of the support rod 92 is fixedly connected to the limit block 93, and the inner wall of the dust removal chamber 1 is respectively provided with square grooves adapted to the slider 83 and the limit block 93.

[0042] The above scheme is adopted: through the design of the spring piece 85 and the spring 86, its function is that when the connecting column 84 drives the slider 83 to move a certain distance, the round block at one end of the limit block 93 moves upward along the trajectory of the slide groove 94. When the limit block 93 moves upward, the spring 86 is squeezed. At the same time, the scraper 91 is driven to move upward through the support rod 92. When the connecting column 84 slides completely to the inside of the horizontal groove of the guide groove 82, the slider 83 is quickly reset along the trajectory of the horizontal groove of the guide groove 82 under the action of the pulling force of the spring piece 85. When the slider 83 is reset, it drives the two limit blocks 93 to slide along the top of the inside of the slide groove 94, so that when the scraper 91 moves in the opposite direction, there is always a gap with the bottom of the inner cavity of the dust removal chamber 1, thereby preventing the scraper 91 from bringing back residual powder when it is reset, thereby ensuring the normal operation of the device;

[0043] When the connecting column 84 drives the slider 83 to fully return to its original position, the limit block 93 is reset along the track of the slide groove 94 under the action of the elastic force of the spring 86, so that the bottom of the scraper 91 is re-contacted with the bottom of the inner cavity of the dust removal chamber 1, thereby facilitating the next use of the device.

[0044] The working principle and use process of the present invention are as follows: the air containing dust is sent into the dust removal chamber 1 through the air inlet pipe 11, and at the same time, the water pump 22 and the first motor 3 are started, so that the water pump 22 extracts the clean water inside the water storage tank 21, and transports it to the inside of the water delivery pipe 5 through the water delivery pipe 23, and then the clean water inside the water delivery pipe 5 passes through the nozzle 6, and passes through the atomizing sheet inside the nozzle 6, and is sprayed into the dust removal chamber 1 in the form of mist. While the first motor 3 is running, it drives the rotating drum 41 to rotate, so that the protrusion on the round rod 43 slides along the trajectory of the arc groove 42, and because the arc groove 42 is corrugated, Therefore, when the drum 41 continues to rotate, the round rod 43 will drive the tooth plate 44 to move back and forth, and then the tooth plate 44 is meshed with the gear 45, so that the water pipe 5 is driven to rotate back and forth through the gear 45, and then the plurality of nozzles 6 at the bottom of the water pipe 5 are swung back and forth, and the nozzles 6 are swung to change the spraying direction of the water mist, so that the water mist is no longer limited to a fixed area, but can cover a larger space range in the dust reduction chamber 1, thereby increasing the probability of capturing dust inside the dust reduction chamber 1 and enhancing the dust reduction effect on the dust inside the dust reduction chamber 1;

[0045] During the dust reduction process, the second motor 7 is started so that the second motor 7 runs once at regular intervals, and each operation will drive the rotating rod 81 to rotate one circle. While the rotating rod 81 rotates, it drives the connecting column 84 to slide along the trajectory of the inclined groove of the guide groove 82, and then drives the two limit blocks 93 to move toward the direction of the second motor 7 through the guide groove 82. While the limit blocks 93 move, the scraper 91 is driven to move in the same direction through the support rod 92, thereby driving the scraper 91 to scrape off the wet dust at the bottom of the inner cavity of the dust reduction chamber 1 to prevent excessive dust from remaining at the bottom and clogging the bottom of the inner cavity of the dust reduction chamber 1.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
