TECHNICAL FIELD

[0001] The utility model relates to a stem signature contains silk static separation device and belongs to the tobacco mechanical equipment field, especially relates to the technology of stem signature contains silk static separation in the tobacco production process. BACKGROUND

[0002] The current stem signature contains silk separation technology has the following deficiencies:

[0003] In the tobacco production process, stem signature removing equipment will be used in different stages and different positions to screen and remove the stem signature mixed in the tobacco to avoid the quality accident of the cigarette and ensure the qualified cigarette products for the consumers. Therefore, the removal rate of the stem signature will be increased, and the problem is that the removed stem signature contains a certain amount of qualified tobacco. If the qualified tobacco cannot be effectively recycled, it will cause waste and does not meet the requirement of reducing loss and increasing efficiency.

[0004] At present, by means of network, the data of the stem signature contains silk static separation device is searched, and no relevant patent data of the stem signature contains silk static separation device is found.

[0005] It is necessary to invent a stem signature contains silk separation device with reasonable structure and high-efficiency and fast static separation device. SUMMARY

[0006] In order to overcome the technical deficiencies of the stem signature contains silk static separation device, a stem signature contains silk static separation device is invented.

[0007] A stem signature contains silk static separation device, a centrifugal vibrating screen, including a feeding port, a trapezoidal screen, a screen box, a discharge port, a static device, an electrostatic generator, a tobacco receiving box, a stem signature and powder receiving box, a powder discharge port; the feeding port is arranged above the leftmost end of the screen, the screen box is arranged below the screen, the screen box powder discharge port is arranged obliquely below the rightmost end of the screen box, the discharge port of the screen is arranged obliquely below the rightmost end of the screen, the stem signature and powder receiving box are arranged directly below the powder discharge port, the tobacco receiving box is arranged side by side with the stem signature and powder receiving box, and a partition plate is arranged between the tobacco receiving box and the stem signature and powder receiving box, the static device is arranged corresponding to the oblique upper side of the discharge port of the screen, and the tobacco receiving box is arranged directly below the static device; the working surface of the static device is separated from the corresponding space of the discharge port of the screen; and the static device is electrically connected with the electrostatic generator.

[0008] The connection relationship of the stem signature contains silk static separation device is that the feeding port is fixed above the leftmost end of the screen, the screen is fixedly connected with the upper part of the screen box, the powder discharge port is fixedly connected with the rightmost end of the screen box, and the discharge port is fixedly connected with the rightmost end of the screen.

[0009] The screen is a trapezoidal screen.

[0010] The screen mesh is smaller than the stem.

[0011] The stem refers to the stem produced in the process of tobacco processing.

[0012] The working process of the stem and tobacco static separation device is as follows: the stem removed from the production line enters the centrifugal vibrating screen through the feeding port, the stem and tobacco are preliminarily separated by the trapezoidal screen in the centrifugal vibrating screen, and the fine and small granular materials are screened, the screened fine and small granular materials are discharged to the stem and powder receiving box through the powder discharge port, and the materials in the centrifugal vibrating screen are discharged through the discharge port, the discharged materials are further separated by the stem and tobacco under the action of the static electric field when passing through the static electric device, the separated tobacco falls into the tobacco receiving box, and the stem falls into the stem and powder receiving box, and the static electric device is connected with the static electric generator.

[0013] The core of the stem and tobacco static separation device is to combine the screening effect of the centrifugal vibrating screen and the charge effect of the static electric field to efficiently separate the stem and tobacco. First, the mixture removed from the production line, mainly containing stem and a small amount of tobacco, enters the centrifugal vibrating screen through the feeding port. In the centrifugal vibrating screen, the trapezoidal screen uses its special structure to preliminarily screen the materials. In this process, larger stems and tobacco clumps are blocked by the screen, while fine and small granular materials, including part of the fine tobacco and impurities, pass through the screen mesh and enter the screen box, and are discharged to the stem and powder receiving box through the powder discharge port.

[0014] The preliminarily screened materials continue to stay in the centrifugal vibrating screen and are further loosened and separated under the action of the vibration and centrifugal force of the screen.

[0015] In the static separation area, a static electric field is provided in the device. This static electric field is powered by the static electric generator and generated through the electrode plate. When the materials pass through the static electric field, due to the difference in electrical properties between the stem and the tobacco, the stem and the tobacco will be affected by the electric field force. The tobacco, due to its good electrical conductivity, is more easily affected by the electric field, thereby changing its trajectory and finally falling into the dedicated tobacco receiving box; the stem, due to its poor electrical conductivity, is less affected by the electric field, so it will fall into the stem and powder receiving box. In this way, the stem and the tobacco are further separated under the action of the static electric field. The working principle of the whole device fully utilizes the combination of physical screening and charge effect to ensure efficient and accurate separation.

[0023] Stem-containing-silk: In the tobacco industry, stem refers to the stem-like material in tobacco, which contains a small amount of tobacco. Stem mainly comes from the veins in tobacco leaves, and although it will be removed in multiple processes during cigarette production, a small amount of stem will still remain in the tobacco.

[0024] Centrifugal vibrating screen: existing known technology, supplied on the market. The principle of centrifugal vibrating screen is mainly based on the screening effect of vibration force on materials, and it produces vibration with a nearly circular trajectory when working. Main components include: exciter: usually installed on the side plate of the screen frame, which is the power source of the vibrating screen. When the motor starts, the eccentric block in the exciter rotates to generate centrifugal force, which is transmitted to the screen surface through the screen frame, forming vibration. Screen box: composed of screen frame and screen mesh, etc., is the main container for material screening. Support device and vibration isolation device: the support device is mainly the elastic element supporting the screen box. The commonly used vibration isolation devices are spiral springs, plate springs and rubber springs, etc., which play the role of support and buffering, ensuring the stability of the vibrating screen during work. Transmission device: vibrating screen usually uses a triangular belt transmission device, which has a simple mechanism and can arbitrarily select the number of revolutions of the vibrator. The centrifugal vibrating screen produces vibration of the screen box through the centrifugal force generated by the exciter, thereby realizing the screening of stem-containing-silk.

[0025] Electrostatic separation device: a kind of electrostatic equipment, used for separating or screening in the mixture of stem and tobacco by using electrostatic effect, so that the amount of tobacco contained in the stem is reduced to the minimum. Existing known technology equipment, according to the specific technical parameters of selection and customization.

[0026] Electrostatic generator: An electrostatic generator is a device capable of generating static electricity. It typically utilizes methods such as friction, separation, or charge transfer to produce static charge on the surface of a non-conductive material or between different media. An electrostatic generator mainly consists of a high-voltage power supply and electrodes, capable of creating a strong electric field between the two electrodes. When the object to be processed is placed between the electrodes, it acquires different amounts of opposite charges due to the applied voltage. Existing known technical equipment is selected and customized according to specific technical parameters.

[0027] The significant features and technological advancements of this utility model's electrostatic separation device for stem-containing fibers are:

[0028] The technical approach is: high-efficiency screening and separation. Vibrating screens utilize mechanical vibration to separate and classify materials. At the same time, combined with the charge effect of electrostatic field, the accuracy and efficiency of separation are further improved.

[0029] The technical objective achieved is to be able to adapt to materials with different particle sizes, humidity levels, and electrostatic properties, and to effectively distinguish between tangled and clumped tobacco shreds in the tobacco sticks, thereby meeting production needs.

[0030] The achieved effects include: strong adaptability, high degree of automation, continuous and stable production, and reduced difficulty and cost of manual operation. Simultaneously, it is environmentally friendly and energy-saving: the electrostatic separation process requires no chemical reagents or other harmful substances, causing no pollution to the environment. The vibrating screen also operates relatively stably, with relatively low noise and energy consumption, helping to reduce production costs and energy consumption. The structure is simple and easy to maintain; the vibrating screen has a relatively simple structure, making it easy to maintain and clean. Furthermore, the design of electrostatic separation devices typically takes into account ease of maintenance. Attached Figure Description
