[0037] Please refer to Figures 1-3 This embodiment provides a cement packaging ash discharge pipe 100, which includes a nozzle 110, a connecting seat 120, and a negative pressure dust suction pipe 130.
[0038] The nozzle 110 is connected to the connecting seat 120; the end of the nozzle 110 is provided with a discharge port 111, and the outer periphery of the nozzle 110 is provided with an exhaust groove 112 along its axial direction;
[0039] The negative pressure suction pipe 130 is connected to the nozzle 110 and is used to communicate with the interior of the nozzle 110 or the exhaust channel 112 to absorb dust in the area of the exhaust channel 112 or dust in the nozzle 110.
[0040] Please refer to Figures 1-3 The working principle of the cement packaging ash discharge pipe 100 is as follows:
[0041] The cement packaging dust discharge pipe 100 includes a nozzle 110, a connecting seat 120, and a negative pressure dust suction pipe 130; the nozzle 110 is connected to the connecting seat 120; the end of the nozzle 110 is provided with a discharge port 111, and the outer periphery of the nozzle 110 is provided with an exhaust groove 112 along its axial direction; the negative pressure dust suction pipe 130 is connected to the nozzle 110 and is used to communicate with the inside of the nozzle 110 or the exhaust groove 112 to absorb dust in the area of the exhaust groove 112 or dust in the nozzle 110.
[0042] During use, the cement packaging dust discharge pipe 100 discharges cement through its discharge port 111. When it extends into the cement bag, the nozzle 110 is equipped with an exhaust groove 112 on its outer periphery. Therefore, when filling the cement bag with cement, the gas can be discharged through the exhaust groove 112, which can prevent the pressure inside the cement bag from becoming too high and exacerbating the situation where cement mixes with air and escapes to the outside. Moreover, the negative pressure dust suction pipe 130 can absorb the dust in the area of the exhaust groove 112 or the dust in the nozzle 110, thereby collecting the dust that escapes during the cement filling process, reducing dust pollution and improving the packaging environment.
[0043] Please refer to Figures 1-3 In this embodiment, a first partition 113 is provided inside the nozzle 110, which divides the interior of the nozzle 110 into a first discharge chamber 114 and a first dust suction chamber 115; the discharge port 111 is connected to the first discharge chamber 114; the cavity wall of the first dust suction chamber 115 is provided with a first dust guide port 116 connected to the first discharge chamber 114 and a second dust guide port 117 connected to the exhaust groove 112; and a negative pressure dust suction pipe 130 is disposed in the first dust suction chamber 115.
[0044] Thus, the first discharge chamber 114 and the first dust suction chamber 115 can be formed by setting the first partition 113. Based on this structure, the dust in the first discharge chamber 114 and the exhaust groove 112 can be collected by the negative pressure dust suction pipe 130 set in the first dust suction chamber 115 through the first dust guide port 116 and the second dust guide port 117 respectively.
[0045] Furthermore, in order to facilitate the collection of dust in the exhaust trough 112 area or the nozzle 110 according to the actual situation, the first dust guide port 116 and the second dust guide port 117 can be staggered along the axial direction of the nozzle 110, and the negative pressure suction pipe 130 can be movably disposed in the first suction chamber 115 so as to absorb dust through the second dust guide port 117, or absorb dust through the first dust guide port 116 and the second dust guide port 117.
[0046] That is, through the above-described structural configuration, the position of the negative pressure suction pipe 130 in the first suction chamber 115 can be adjusted so that the negative pressure suction pipe 130 is connected to the second dust guide port 117, or connected to the first dust guide port 116 and the second dust guide port 117, thereby adjusting the suction area state so as to adjust the suction state according to the usage requirements and improve its usage flexibility.
[0047] Furthermore, in order for the negative pressure suction pipe 130 to be connected to the second dust guide port 117, or to the first dust guide port 116 and the second dust guide port 117, the second dust guide port 117 is located in front of the first dust guide port 116 along the axial direction of the nozzle 110.
[0048] In order to drive the negative pressure suction pipe 130 to move relative to the first suction chamber 115, the cement packaging ash discharge pipe 100 in this embodiment also includes a driving unit 140. The driving unit 140 is connected to the connecting seat 120 and is used to drive the negative pressure suction pipe 130 to move relative to the first suction chamber 115.
[0049] Furthermore, when the negative pressure suction pipe 130 moves relative to the first suction chamber 115, in order to improve its sealing performance, the negative pressure suction pipe 130 includes a pipe body 131, a slip ring 132, and a suction nozzle 133; the slip ring 132 is sleeved on the pipe body 131 and slidably engages with the first suction chamber 115; the pipe body 131 is connected to the drive unit 140; and the suction nozzle 133 is located on the side of the slip ring 132 away from the drive unit 140.
[0050] Unlike the arrangement of the first partition 113 described above, please refer to... Figures 1-4 In an embodiment of this utility model, two second partitions 151 are provided inside the nozzle 110, which divide the inside of the nozzle 110 into a second discharge chamber 152, a second dust suction chamber 153 and a third dust suction chamber 154.
[0051] The discharge port 111 is connected to the second discharge chamber 152; the cement packaging ash discharge pipe 100 includes two negative pressure dust suction pipes 130, which are respectively installed in the second dust suction chamber 153 and the third dust suction chamber 154.
[0052] The second dust suction chamber 153 is connected to the second discharge chamber 152, and the third dust suction chamber 154 is connected to the exhaust channel 112.
[0053] Furthermore, the wall of the second dust suction chamber 153 is provided with a third dust guide port 155 that communicates with the second discharge chamber 152, and the wall of the third dust suction chamber 154 is provided with a fourth dust guide port 156 that communicates with the exhaust groove 112.
[0054] That is, by setting two second partitions 151, a second discharge chamber 152, a second dust suction chamber 153 and a third dust suction chamber 154 can be formed. Based on this, by configuring two negative pressure dust suction pipes 130, the dust suction control of the exhaust groove 112 and the nozzle 110 can be realized by independently controlling the two negative pressure dust suction pipes 130, thereby improving the flexibility of use.
[0055] When configuring the exhaust groove 112, in order to avoid it affecting the loading at the discharge port 111 during the dust collection process, the exhaust groove 112 is set at an angle to the discharge port 111 around the axis of the nozzle 110, and the included angle between the discharge port 111 and the exhaust groove 112 is greater than 90°.
[0056] Based on the above, please refer to Figures 1-4 This embodiment also provides a cement packaging system 200, which includes a material guiding component, a dust collection and recovery component 210, and the aforementioned cement packaging ash discharge pipe 100.
[0057] The material feeding assembly is connected to the cement packaging ash discharge pipe 100 to deliver cement to the nozzle 110; the dust collection and recovery assembly 210 is connected to the negative pressure dust suction pipe 130 to absorb and recover cement in the dust, and transport the recovered cement to the material feeding assembly.
[0058] It should be noted that the cement packaging system 200 includes the aforementioned cement packaging ash discharge pipe 100, which possesses all the advantages of the aforementioned cement packaging ash discharge pipe 100. On this basis, when configuring the dust collection and recovery component 210, it can include a bag filter, a dust collection inlet, and a conveying device. A dust collection inlet connected to the negative pressure suction pipe 130 is provided in the middle of the side wall of the dust collector. The dust sucked in by the negative pressure suction pipe 130 can be recovered into the dust collector. The cement residue after being treated by the dust collector can be conveyed back into the cement packaging machine through the conveying device to achieve recycling.
[0059] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
