Description

Technical Field

[0001] This utility model relates to the field of horizontal screw centrifuge technology, and in particular to a sound-insulating and noise-reducing horizontal screw centrifuge. Background Technology

[0002] Horizontal screw centrifuges are commonly used centrifuge equipment that uses centrifugal force to separate solid particles or suspended matter in a mixture, causing them to settle to the bottom of the centrifuge. They are widely used in chemical, food, pharmaceutical, and environmental protection industries, effectively improving production efficiency and product quality. The vibration and noise issues of horizontal screw centrifuges are of great importance to safe production; therefore, there is an urgent need for a sound-insulating and noise-reducing horizontal screw centrifuge.

[0003] When a horizontal decanter centrifuge is working, the high-speed rotation of the drum relative to the shell generates significant vibration and noise. To address this, lubricating oil is applied to the connection between the shell and the drum to reduce friction. However, the current method of applying lubricating oil is manual. This manual application can result in either too much or too little lubricating oil being applied. Furthermore, manual application can only be performed when the centrifuge is stopped, and cannot be done while the centrifuge is running, which affects the sound insulation and noise reduction effect of the centrifuge. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides a sound-insulating and noise-reducing horizontal screw centrifuge. By improving the structure of the horizontal screw centrifuge, the sound insulation and noise reduction effect of the centrifuge can be improved.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A sound-insulating and noise-reducing horizontal decanter centrifuge includes: a motor, a housing, a rotating drum, and an applicator mechanism. The rotating drum is located inside the housing, the motor is located on one side of the housing, and the rotating drum is connected to the drive end of the motor. The applicator mechanism is installed at the connection between the housing and the rotating drum. The applicator mechanism includes: a liquid storage tank, a spray pipe, and a solenoid valve. The inlet of the spray pipe is connected to the liquid storage tank, and the liquid storage tank stores lubricating oil. The solenoid valve is installed on the spray pipe. The liquid storage tank and the solenoid valve are both installed on the outer wall of the housing.

[0007] Therefore, by setting up an application mechanism at the connection between the shell and the drum, lubricating oil can be applied to the horizontal decanter centrifuge without stopping the machine. Compared with the existing manual application method, this method is simple in structure and easy to operate. Through the solenoid valve, lubricating oil can be applied to the connection between the shell and the drum at any time during the operation of the horizontal decanter centrifuge, so as to reduce the friction between the shell and the drum and improve the sound insulation and noise reduction effect of the horizontal decanter centrifuge. In addition, the solenoid valve can achieve quantitative application of lubricating oil, thus avoiding waste due to excessive application of lubricating oil and failure to reduce friction due to insufficient application of lubricating oil.

[0008] As a further improvement to the above technical solution: multiple spray pipes are provided, and the number of solenoid valves is equal to the number of spray pipes; the outlets of the multiple spray pipes are distributed in a ring with equal spacing. Therefore, through the multiple equally spaced ring-shaped spray pipe outlets, it can be ensured that lubricating oil is evenly applied to the outer circumference of the connection between the housing and the drum, thus ensuring that the frictional force at all points around the connection between the housing and the drum is reduced.

[0009] As a further improvement to the above technical solution, it also includes: a sound insulation and noise reduction mechanism, which is installed on the outer wall of the housing.

[0010] As a further improvement to the above technical solution: the sound insulation and noise reduction mechanism includes: a sound-absorbing panel and a sound-insulating panel, wherein the sound-absorbing panel is installed on the outer wall of the housing, and the sound-insulating panel is installed on the outer wall of the sound-absorbing panel.

[0011] As a further improvement to the above technical solution: the sound-absorbing panel has a hollow structure, and the interior of the sound-absorbing panel is filled with sponge strips, which are corrugated. Therefore, during the operation of the horizontal screw centrifuge, the noise generated is absorbed by the sponge strips, and in conjunction with the sound insulation panel, it can block noise from inside the shell, ensuring that noise inside the shell does not transmit outwards, thereby further improving the sound insulation and noise reduction effect of the horizontal screw centrifuge.

[0012] As a further improvement to the above technical solution, it also includes: a spiral feeder and a feed pipe, wherein the spiral feeder is located inside the drum and connected to the drum, and the feed pipe is located inside the spiral feeder, with one end of the feed pipe extending from the other side of the housing to the outside of the housing.

[0013] As a further improvement to the above technical solution, it also includes: a first discharge port and a second discharge port, wherein the first discharge port is installed on the side of the drum away from the motor, and the second discharge port is installed on the side of the drum closer to the motor. Thus, the solid after solid-liquid separation is discharged through the first discharge port, and the liquid after solid-liquid separation is discharged through the second discharge port.

[0014] As a further improvement to the above technical solution, it also includes: a baffle plate, which is located inside the housing and on the side of the drum closest to the housing, and is installed between the housing and the drum. Thus, the baffle plate ensures that lubricating oil does not enter the housing.

[0015] As a further improvement to the above technical solution, it also includes: a coupling and a differential, wherein the drive end of the motor is connected to the coupling, the coupling is connected to the differential, and the differential is connected to the drum.

[0016] As a further improvement to the above technical solution, it also includes: a base, wherein the motor and the housing are both connected to the base.

[0017] The beneficial effects of this utility model are as follows:

[0018] By incorporating a coating mechanism at the connection between the shell and the drum, lubricating oil can be applied to the horizontal decanter centrifuge without stopping the machine. Compared to the existing manual coating method, this method is simpler in structure and easier to operate. Through a solenoid valve, lubricating oil can be applied to the connection between the shell and the drum at any time during the operation of the horizontal decanter centrifuge, thereby reducing the friction between the shell and the drum and improving the sound insulation and noise reduction effect of the horizontal decanter centrifuge. In addition, the solenoid valve can achieve quantitative application of lubricating oil, thus avoiding waste due to excessive application of lubricating oil and insufficient application of lubricating oil to achieve the effect of reducing friction.

[0019] This utility model also has the following advantages:

[0020] 1. This utility model, through multiple equally spaced annularly distributed liquid outlets of the spray pipes, can ensure that the outer circumference of the connection between the housing and the drum is evenly coated with lubricating oil, thereby ensuring that the friction at all points around the connection between the housing and the drum is reduced.

[0021] 2. During the operation of the horizontal screw centrifuge, the noise generated by the present invention is absorbed by the sponge strips, and with the cooperation of the sound insulation board, the noise inside the shell can be blocked to ensure that the noise inside the shell will not be transmitted to the outside, thereby further improving the sound insulation and noise reduction effect of the horizontal screw centrifuge.

[0042] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0043] like Figures 1 to 5The diagram shows the preferred embodiment of this utility model. The sound-insulating and noise-reducing horizontal screw centrifuge of this embodiment includes: a motor 1, a housing 2, a rotating drum 3, and a coating mechanism 4. The rotating drum 3 is located inside the housing 2, and the motor 1 is located on one side of the housing 2. The rotating drum 3 is connected to the drive end of the motor 1. The coating mechanism 4 is installed at the connection between the housing 2 and the rotating drum 3. The coating mechanism 4 includes: a liquid storage tank 401, a spray pipe 402, and a solenoid valve 403. The liquid storage tank 401 stores lubricating oil. The inlet of the spray pipe 402 is connected to the liquid storage tank 401. The solenoid valve 403 is installed on the spray pipe 402. The liquid storage tank 401 and the solenoid valve 403 are both installed on the outer wall of the housing 2. Therefore, by providing an application mechanism 4 at the connection between the shell 2 and the drum 3, the horizontal decanter centrifuge can be continuously lubricated without stopping the machine. Compared with the existing manual application method, this method is simple in structure and easy to operate. Through the solenoid valve 403, lubricating oil can be applied to the connection between the shell 2 and the drum 3 at any time during the operation of the horizontal decanter centrifuge, so as to reduce the friction between the shell 2 and the drum 3 and improve the sound insulation and noise reduction effect of the horizontal decanter centrifuge. In addition, the solenoid valve 403 can achieve quantitative application of lubricating oil, thus avoiding waste due to excessive application of lubricating oil and failure to reduce friction due to insufficient application of lubricating oil.

[0044] In other words, when the horizontal decanter centrifuge is working, the rotation of the drum 3 relative to the shell 2 can generate a large vibration. By applying lubricating oil at the connection between the shell 2 and the drum 3, the friction between the shell 2 and the drum 3 can be reduced, thereby eliminating the noise generated when the shell 2 and the drum 3 rotate relative to each other. The application mechanism 4 can apply lubricating oil at any time and is not affected by the working state of the horizontal decanter centrifuge.

[0045] In this embodiment, multiple spray pipes 402 are provided, and the number of solenoid valves 403 is equal to the number of spray pipes 402; the outlets of the multiple spray pipes 402 are distributed in a ring with equal spacing. Therefore, through the multiple equally spaced ring-shaped outlets of the spray pipes 402, it can be ensured that a uniform layer of lubricating oil is applied around the outer periphery of the connection between the housing 2 and the drum 3, thus ensuring that the frictional force at all points around the connection between the housing 2 and the drum 3 is reduced.

[0046] In this embodiment, a sound insulation and noise reduction mechanism 5 is also included, which is installed on the outer wall of the housing 2. The sound insulation and noise reduction mechanism 5 includes a sound-absorbing plate 501 and a sound-insulating plate 502. The sound-absorbing plate 501 is installed on the outer wall of the housing 2, and the sound-insulating plate 502 is installed on the outer wall of the sound-absorbing plate 501. The sound-absorbing plate 501 has a hollow structure, and the interior of the sound-absorbing plate 501 is filled with sponge strips 503, which are corrugated. Thus, during the operation of the horizontal screw centrifuge, the noise generated is absorbed by the sponge strips 503, and with the cooperation of the sound-insulating plate 502, the noise inside the housing 2 can be blocked to ensure that the noise inside the housing 2 will not be transmitted to the outside, thereby further improving the sound insulation and noise reduction effect of the horizontal screw centrifuge.

[0047] In this embodiment, it also includes: a spiral feeder 6 and a feed pipe 7. The spiral feeder 6 is located inside the rotating drum 3 and is connected to the rotating drum 3. The feed pipe 7 is located inside the spiral feeder 6, and one end of the feed pipe 7 extends from the other side of the housing 2 to the outside of the housing 2.

[0048] In this embodiment, the system further includes a first discharge port 8 and a second discharge port 9. The first discharge port 8 is installed on the side of the drum 3 away from the motor 1, and the second discharge port 9 is installed on the side of the drum 3 closer to the motor 1. Thus, the solid after solid-liquid separation is discharged through the first discharge port 8, and the liquid after solid-liquid separation is discharged through the second discharge port 9.

[0049] Specifically, the first discharge port 8 is a solid discharge port, and the second discharge port 9 is a liquid discharge port.

[0050] In this embodiment, a baffle plate 10 is also included. The baffle plate 10 is located inside the housing 2 and on the side of the drum 3 closest to the housing 2, and is installed between the housing 2 and the drum 3. Thus, the baffle plate 10 can ensure that lubricating oil does not enter the interior of the housing 2.

[0051] In this embodiment, it also includes a coupling 11 and a differential 12. The drive end of the motor 1 is connected to the coupling 11, the coupling 11 is connected to the differential 12, and the differential 12 is connected to the drum 3.

[0052] In this embodiment, it also includes: a base 13, and the motor 1 and the housing 2 are both connected to the base 13.

[0053] The working process of this utility model of horizontal screw centrifuge is as follows: First, the material to be separated into solid and liquid is injected into the screw feeder 6 through the feed pipe 7; finally, the motor 1 and solenoid valve 403 are started, and with the cooperation of coupling 11 and differential gear 12, the drum 3 and the screw feeder 6 rotate to achieve solid-liquid separation of the material. The solid after solid-liquid separation is discharged through the first discharge port 8, and the liquid after solid-liquid separation is discharged through the second discharge port 9. Through the cooperation of solenoid valve 403 and spray pipe 402, lubricating oil can be applied to the connection between shell 2 and drum 3 when the horizontal screw centrifuge is working. In this way, the friction between shell 2 and drum 3 can be reduced, and the vibration generated when drum 3 rotates relative to shell 2 can be eliminated. In addition, the noise reduction mechanism 5 can eliminate the noise generated when the horizontal screw centrifuge is working and prevent the noise inside shell 2 from being transmitted to the outside, so as to improve the noise reduction effect of the horizontal screw centrifuge.

[0054] In summary, this utility model, by providing an application mechanism 4 at the connection between the housing 2 and the drum 3, enables the application of lubricating oil to the horizontal decanter centrifuge without stopping the machine. Compared with the existing manual application method, this method has a simple structure and is easy to operate. Through the solenoid valve 403, lubricating oil can be applied to the connection between the housing 2 and the drum 3 at any time during the operation of the horizontal decanter centrifuge, so as to reduce the friction between the housing 2 and the drum 3 and improve the sound insulation and noise reduction effect of the horizontal decanter centrifuge. In addition, the solenoid valve 403 can realize the quantitative application of lubricating oil, thus avoiding the waste of too much lubricating oil or the failure to achieve the effect of reducing friction due to too little lubricating oil.
