Description

Technical Field

[0001] The utility model belongs to the technical field of reconstituted tobacco production, in particular to an external lubrication system for reconstituted tobacco decanter equipment using a papermaking method. Background Art

[0002] Papermaking-based reconstituted tobacco, commonly known as tobacco flakes, uses tobacco waste such as tobacco stems, cigarette dust and fragments as the main raw materials. The tobacco raw materials are impregnated with water, and then the water-soluble and insoluble substances in the tobacco are separated into solid and liquid. With the help of papermaking equipment and technology, the insoluble substances such as tobacco fibers are dispersed in water and then made into a fiber sheet base by a papermaking machine. At the same time, the water-soluble substances are concentrated and then coated back onto the sheet base. After drying, it becomes papermaking-based reconstituted tobacco.

[0003] In the production of reconstituted tobacco using the papermaking method, the horizontal decanter centrifuge (or decanter for short) is a key equipment process. This process is crucial for separating the extract and coating liquid solids, maintaining the fluidity of the coating liquid, and ensuring coating quality. The drum bearings of this equipment are lubricated with grease, and lubrication is performed manually once a day. Observations show that each time grease is added, the bearings accumulate and experience a temperature rise that can persist for more than half an hour. This excessive temperature can affect bearing life. This frequent lubrication also makes it easy to miss lubrication procedures. Summary of the Invention

[0004] The purpose of the utility model is to address the deficiencies of the above-mentioned prior art and to provide an external lubrication system for a papermaking method reconstituted tobacco leaf decanter equipment, so as to achieve automatic lubrication of the drum bearings in small quantities at multiple frequencies.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] An external lubrication system for a papermaking process reconstituted tobacco decanter comprises a quantitative grease pump and a grease tank provided on the outside of the decanter. The decanter is controlled by a control system configured to start and stop the quantitative grease pump. The quantitative grease pump is connected to bearing seats on both sides of the decanter via two oil pipes configured to be laid out in the same manner and connected to the bearing seats via a movable threaded head configured to be provided.

[0007] The quantitative grease pump is also equipped with a timing device, which can set and display the single running time of the quantitative grease pump and the running interval time of the lubrication pump.

[0008] A thread head for connection is fixedly provided on the bearing seat, and a movable thread head is matched with the thread head and leads to a bearing chamber of the bearing seat.

[0009] The quantitative grease pump is also equipped with a pressure gauge for displaying the outlet pressure of the grease pump when delivering and supplying grease.

[0010] The control system outputs an operating signal through a program to control the intermediate relay to be closed, thereby supplying power to the quantitative grease pump.

[0011] The grease pump is provided with a transparent observation port.

[0012] The oil pipe has a diameter of 5 to 10 mm.

[0013] The oil pipe has a diameter of 8 mm.

[0021] The following describes the implementation of the present invention through specific embodiments. People familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0022] The utility model provides an external lubrication system for a papermaking method reconstituted tobacco leaf horizontal screw machine. Figure 1 and Figure 2 shown.

[0023] An external lubrication system for papermaking reconstituted tobacco decanter equipment includes a quantitative grease pump 2 and a grease tank 3 provided on the outside of the decanter 1. The decanter 1 controls the quantitative grease pump 2 via a control system, and the quantitative grease pump 2 leads to bearing seats 5 on both sides of the decanter via two oil pipes 4. The two oil pipes 4 are arranged in the same manner and connected to the bearing seats 5 via a movable threaded head 7. The quantitative grease pump 2 is also provided with a grease tank 3, which is responsible for storing grease, while the quantitative grease pump 2 performs timed and quantitative grease delivery to provide quantitative and multi-frequency grease lubrication to the lubricated parts.

[0024] The quantitative grease pump 2 is also equipped with a timing device 6, which can set and display the single running time of the quantitative grease pump 2 and the running interval of the lubrication pump. In this embodiment, the single running time of the quantitative grease pump is set in seconds, and the setting range is 0-99; the running interval of the quantitative grease pump 2 is set in minutes, and the setting range is 0-999.

[0025] To achieve this connection, a threaded head is fixed to the bearing seat 5. A movable threaded head 7 is provided with the threaded head and leads to the bearing chamber of the bearing seat 5, facilitating quick connection and real-time lubrication. The oil pipe 4 can deliver grease to the outer bearing of the equipment drum that needs lubrication. The grease is a high-viscosity special grease, which can prevent clogging of the oil pipe to a certain extent.

[0026] The grease pump 2 is provided with a transparent observation port, which has a transparent appearance and a large transparent observation port, making it convenient to observe the grease inventory and replenish it.

[0027] The quantitative grease pump 2 is also equipped with a pressure gauge for displaying the outlet pressure of the grease pump when the grease is being transported and supplied.

[0028] To effectively prevent the oil pipe from being blocked, the diameter of the oil pipe is 5~10mm. In this embodiment, the diameter of the oil pipe is 8mm. To ensure that the two bearing seats are greased with the same amount of grease at the same time, two oil pipes of the same length are selected, and a movable threaded joint is used to connect the bearing seat and the oil pipe.

[0029] The power supply 8 of the horizontal screw machine is set in the horizontal screw machine control cabinet. When the horizontal screw machine is running, the program outputs an operating signal to control the intermediate relay to be attracted, and the quantitative grease pump is powered. After the machine is shut down, the quantitative grease pump is also powered off, and the grease pump and its grease tank are started and shut down at the same time as the horizontal screw machine.

[0030] When the equipment is running, the lubrication system starts immediately, delivers grease once according to the pre-set duration, and starts timing; after the pre-set lubrication cycle duration, the grease is delivered once according to the pre-set duration, and the timing is restarted, and the grease is delivered in a timely and quantitative manner in this cycle.

[0031] The external lubrication system of the horizontal spiral centrifuge for papermaking reconstituted tobacco is suitable for the external lubrication system of the horizontal spiral centrifuge used to process extracts and coating liquids of papermaking reconstituted tobacco. It has the characteristics of good effect, simple operation, simple structure, high degree of automation, low cost and easy installation. It can be applied to equipment that requires high-frequency manual grease supply for reconstituted tobacco, and can also be used for precision equipment in the industry that has strict requirements on bearing temperature rise.
