[0002] The working principle of a metal mold centrifugal casting machine is based on centrifugal casting technology. Molten metal is poured into a high-speed rotating metal mold, and under the action of centrifugal force, the molten metal fills the mold and forms a casting.
[0003] The casting process generates dust that pollutes the environment. Dust is removed by connecting a suction device via a connecting pipe. For example, Chinese Patent Publication No. CN211161820U discloses a suction device for a centrifugal pipe casting machine, belonging to the field of mechanical equipment. This utility model includes a suction pipe and an exhaust pipe. Its structural features include a first swing pipe, a second swing pipe, and a connecting structure between the swing pipes. The suction pipe is connected to the first swing pipe, the first swing pipe and the second swing pipe are connected via the swing pipe connecting structure, and the second swing pipe is connected to the exhaust pipe. The first and second swing pipes swing more flexibly, achieving better dust removal efficiency.
[0004] In actual operation, since the centrifuge is moving during the production process, the original dust removal pipe system connects the equipment and the dust collector by rotating flexible hoses. However, due to the negative pressure and torque generated in the pipeline, the hoses are frequently damaged. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of the existing technology, such as frequent damage to the hoses, and to propose a dust removal active pipe structure for a centrifugal casting machine.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design a dust removal movable pipe structure for a centrifugal pipe casting machine, including a support, a movable trolley slidably connected to the top of the support, and a movable centrifugal device provided at the bottom of the support via a drive device, wherein the movable trolley and the openings at both ends of the centrifugal device are connected by a connecting structure.
[0008] The bracket has a dust removal trough inside, and the mobile trolley communicates with the dust removal trough through a bottom opening. The opening of the dust removal trough is sealed by a closure assembly between the mobile trolley and the bracket.
[0009] Furthermore, the connection structure includes a spigot dust cover and a socket dust cover. The spigot dust cover is connected to the socket dust cover via a rotating device and a connecting pipe. The spigot dust cover and the socket dust cover are respectively connected to the two end openings of the centrifuge device. The connecting pipe is also connected to the moving trolley.
[0010] Furthermore, the closing assembly includes guide pulleys, the top of the bracket is connected to the dust removal trough and slidably connected to the mobile trolley, the guide pulleys are rotatably connected to the left and right ends of the bracket and the periphery of the mobile trolley, and a flat belt is sleeved on the periphery of several guide pulleys through a tension adjustment assembly.
[0011] Furthermore, the two ends of the flat belt are fixedly connected to the bottom ends of the bracket, and the flat belt matches the top opening of the dust collection trough, wherein the dust collection trough is connected to the dust collector through a dust collection pipe.
[0012] Furthermore, the tension adjustment assembly includes a housing, which is installed at the bottom of one end of the bracket. Inside the housing, a sliding member and an adjusting member are slidably connected via a sliding groove. The side of the housing is connected to the sliding groove to form a guide groove. The shaft end of the sliding member is located in the guide groove and is rotatably connected to the guide pulley on its periphery.
[0013] Furthermore, it also includes an adjusting screw, which is rotatably connected to the top of the housing, and is threadedly connected to the adjusting member. A compression spring is provided between the adjusting member and the sliding member.
[0014] The present invention proposes a dust removal movable pipe structure for a centrifugal casting machine, which has the following advantages: The present invention is equipped with a connecting structure and a closing component. The centrifuge and the moving trolley are connected through the connecting structure, so that the vacuum cleaner can be paired with the closing component to clean the dust in the dust removal tank. The moving trolley and the centrifuge move synchronously and parallel through the connecting pipe, which prevents the connecting pipe from being frequently damaged. In addition, considering that the flat belt is prone to aging and elongation after long-term use, resulting in a decrease in sealing effect, a tension adjustment component is also provided between the flat belt and the guide pulley. The sealing of the top opening of the dust removal tank is ensured by tensioning the flat belt. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-5 A dust removal movable pipe structure for a centrifugal pipe casting machine includes a support 1, a movable trolley 2 slidably connected to the top of the support 1, and a movable centrifugal device 3 provided at the bottom of the support 1 via a drive device. The movable trolley 2 and the openings at both ends of the centrifugal device 3 are connected by a connecting structure 4.
[0023] The bracket 1 has a dust removal groove inside, and the mobile trolley 2 communicates with the dust removal groove through a bottom opening. The mobile trolley 2 and the bracket 1 are sealed by a closure assembly 5.
[0024] It should be added that the driving device can be a ball screw assembly, which drives the centrifugal device 3 to move and unload the cast pipe. Specifically, during the movement, the moving trolley 2 and the centrifugal device 3 move synchronously and in parallel.
[0025] Furthermore, the connection structure 4 includes a spigot dust cover 41 and a socket dust cover 42. The spigot dust cover 41 is connected to the socket dust cover 42 through a rotating device 43 and a connecting pipe 44. The spigot dust cover 41 and the socket dust cover 42 are respectively connected to the two ends of the centrifugal device 3. The connecting pipe 44 is also connected to the mobile trolley 2.
[0026] Furthermore, the closing component 5 includes guide pulleys 51. The top of the bracket 1 is connected to the dust removal trough and slidably connected to the mobile trolley 2. The guide pulleys 51 are rotatably connected to the left and right ends of the bracket 1 and the periphery of the mobile trolley 2. A flat belt 52 is sleeved on the periphery of several guide pulleys 51 through a tension adjustment component 6.
[0027] It should be added that the dust generated during the pipe casting process is high temperature. The flat belt 52 is in contact with the high temperature dust for a long time, and gradually ages and stretches due to the pulling of the moving trolley 2. The tension of the flat belt 52 is adjusted by the tension adjustment component 6 to prevent the stretched flat belt 52 from failing to seal the top opening of the dust removal tank.
[0028] More specifically, the two ends of the flat belt 52 are fixedly connected to the bottom ends of the bracket 1, and the flat belt 52 matches the top opening of the dust collection trough, wherein the dust collection trough is connected to the dust collector through the dust collection pipe 7.
[0029] In general, the tension adjustment assembly 6 includes a housing 61, which is installed at the bottom of one end of the bracket 1. Inside the housing 61, a sliding member 62 and an adjusting member 63 are slidably connected via a sliding groove. The side of the housing 61 is connected to the sliding groove to form a guide groove 64. The shaft end of the sliding member 62 is located in the guide groove 64 and is rotatably connected to the guide pulley 51 on its periphery.
[0030] Finally, it also includes an adjusting screw 65, which is rotatably connected to the top of the housing 61. The adjusting screw 65 is threadedly connected to the adjusting member 63, and a compression spring 66 is provided between the adjusting member 63 and the sliding member 62.
[0031] In specific operation, rotating the adjusting screw 65 drives the adjusting component 63 to move downwards. The adjusting component 63 and the sliding component 62 adjust the travel of the bottom guide pulley 51 by pressing the spring 66, thereby achieving the function of adjusting the tension of the flat belt 52.
[0032] Working method: During operation, the mobile trolley 2 is connected to the dust removal tank and the connecting pipe 44. When the centrifuge moves, the mobile trolley 2 also moves on the dust removal tank along with the centrifuge. A flat belt 52 is placed on the dust removal tank and the mobile trolley 2 to seal the dust removal tank and prevent the smoke and dust from overflowing.
[0033] Dust enters the mobile trolley 2 through the connecting pipe 44, and then enters the dust removal tank through the opening at the bottom of the mobile trolley 2. At the bottom of the support 1, a dust collector is connected through the dust removal pipe 7. The dust collector and the dust removal pipe 7 clean the dust in the dust removal tank and then discharge it into the atmosphere.
[0034] When the flat belt 52 ages and stretches after prolonged use, rotating the adjusting screw 65 drives the adjusting component 63 to move downward. The adjusting component 63 and the sliding component 62 adjust the travel of the bottom guide pulley 51 by pressing the spring 66, thereby adjusting the tension of the flat belt 52.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
