Description

Technical Field

[0001] This application belongs to the field of cigarette equipment technology, specifically relating to a discharge hood structure for a cylindrical equipment. Background Technology

[0002] In industrial fields such as cigarette production, cylindrical equipment (such as tobacco drying machines, rehumidification cylinders, flavoring cylinders, etc.) are the core equipment for material processing. Their discharge hoods, as key structures connecting the equipment body and downstream conveying devices, mainly undertake functions such as material guidance, heat insulation, and environmental protection.

[0003] In existing technologies, the structural design of discharge hoods for cylindrical equipment typically employs a main frame constructed from profiles. The inner wall of the frame is fixed with steel plates via a fully connected method. The frame is filled with insulation material, and finally, an outer steel plate encapsulates and covers the entire structure. Because the inner steel plate and the profile frame are connected by large-area tight welding, the large contact area and the high thermal conductivity of steel allow heat inside the discharge hood to be easily and rapidly conducted to the external environment through the large contact area between the inner wall and the frame. This heat conduction path directly causes significant heat loss, resulting in a rapid temperature drop in the material inside the discharge hood (such as tobacco shreds and leaves in cigarette production) during the discharge process. This not only affects the stability of subsequent processing but may also cause condensation due to alternating hot and cold temperatures, leading to moisture absorption, clumping, or adhesion to the inner wall, ultimately affecting product quality.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] See also Figure 1-4 As shown, an embodiment of this application provides a discharge hood structure for a cylindrical device, comprising: Main frame 1; The side wall includes an inner wall 2, which is disposed inside the main frame 1 and forms a sealed space within the enclosure of the main frame 1. The inner wall 2 is fixedly connected to the main frame 1 through a point connection structure, so that a gap is formed between the inner wall 2 and the main frame 1 that is not fully fitted.

[0023] In this technical solution, the discharge hood structure for cylindrical equipment provided in this application includes a main frame 1 and side walls. The side walls include an inner wall 2, which is disposed inside the main frame 1 and forms a sealed space within the space defined by the main frame 1. The inner wall 2 and the main frame 1 are fixedly connected by a point connection structure, resulting in a non-fully fitted gap between the inner wall 2 and the main frame 1. During the operation of cylindrical equipment (such as tobacco drying machines and rehumidification cylinders in cigarette production), the sealed space of this discharge hood structure can achieve stable guiding and conveying of materials, preventing materials from scattering or splashing during discharge. The point connection structure between the inner wall 2 and the main frame 1 reduces the heat conduction contact area between the inner wall 2 and the main frame 1. Compared to the large-area contact between the inner wall 2 and the frame, this reduces heat loss within the sealed space, maintains a stable temperature within the sealed space, and prevents materials from becoming damp, clumping, or adhering to the inner wall 2 due to condensation caused by sudden temperature drops, thus ensuring product quality.

[0024] It is understandable that the point connection structure between the inner wall 2 and the main frame 1 can be either a number of discretely distributed spot welds or a local contact fixation achieved through structures such as protruding connecting blocks and connecting columns. The purpose of the connection is to block the heat conduction path by reducing the actual contact area, while ensuring the connection strength between the inner wall 2 and the main frame 1.

[0025] In one feasible embodiment, the point connection structure is a spot welding structure.

[0026] In this technical solution, the spot welding structure achieves a stable connection between the inner wall 2 and the main frame 1 through several discretely distributed welding points. Compared with traditional large-area bonding welding, the spot welding structure can reduce the actual contact area between the inner wall 2 and the frame. Since steel is a high thermal conductivity material, traditional large-area contact will cause heat to dissipate rapidly, while discrete welding points only form local contact points. Combined with the gap of non-full bonding, the heat loss in the sealed space is reduced. The reduction of heat loss can maintain the temperature stability in the sealed space, avoid the material from condensing due to sudden temperature drop and contact with cold air, and thus prevent the material from getting damp, clumping or adhering to the inner wall 2, ensuring the quality of products processed in subsequent stages.

[0027] In one feasible embodiment, the sidewall further includes: Outer wall 3, the outer wall 3 is disposed on the outside of the main frame 1, and an insulation space is formed between the outer wall 3 and the inner wall 2; A thermal insulation layer is disposed in the thermal insulation space between the inner wall 2 and the outer wall 3; An electric heating element is disposed between the insulation layer and the inner wall 2.

[0028] The electric heating element is an electric heating blanket.

[0029] In this technical solution, the sidewall also includes an outer wall 3, an insulation layer, and an electric heating element. When the cylindrical equipment completes material processing and conveys the material through the discharge hood, the point connection structure between the inner wall 2 and the main frame 1 reduces the heat conduction contact area. The insulation layer installed in the sealed insulation space enclosed by the outer wall 3 and the inner wall 2 further blocks air convection heat dissipation, effectively preserving the heat within the sealed space. Simultaneously, the electric heating element, positioned between the inner wall 2 and the insulation layer, directly conducts heat to the inner wall 2 and radiates it into the sealed space, reducing heat loss during the transfer process. This not only maintains a stable temperature within the sealed space, preventing condensation from the material due to sudden temperature drops and contact with cold air, thus preventing the material from becoming damp, clumping, or adhering to the inner wall 2, ensuring product quality consistency, but also provides continuous heat replenishment for the material, ensuring the stability of subsequent processing. Furthermore, the insulation layer reduces heat loss from the electric heating element to the external environment, lowering heating power consumption.

[0030] Understandably, the material of the insulation layer can be selected according to actual insulation needs, operating temperature and environmental protection requirements, such as rock wool, glass wool, polyurethane foam, etc.

[0031] It is understandable that the electric heating element can be an electric heating blanket, and the electric heating element can also be equipped with a temperature sensor and a thermostat to achieve temperature adjustment and control.

[0032] It is understandable that the connection between the outer wall 3 and the main frame 1 can be achieved by welding, bolting, or other methods. After installation, these methods are used to ensure the airtightness of the insulated space and prevent air convection from damaging the insulation effect.

[0033] In one feasible embodiment, the side wall is provided with an inlet 4 and an outlet 5, both of which are connected to the sealed space.

[0034] In this technical solution, a feed inlet 4 and a discharge outlet 5 are provided on the side wall, and both the feed inlet 4 and the discharge outlet 5 are connected to the sealed space. After the cylindrical equipment completes the material processing, the material can enter the sealed space through the feed inlet 4 and then be discharged to the downstream conveying device through the discharge outlet 5. Since the feed inlet 4 and the discharge outlet 5 are directly connected to the sealed space, and the sealed space has good sealing performance, it can not only prevent the material from scattering and splashing during the conveying process, reducing material loss, but also prevent the exhaust gas generated during the processing from escaping from the feed inlet 4 and the discharge outlet 5, thus ensuring the workshop working environment.

[0035] Understandably, the positions of the inlet 4 and outlet 5 can be set according to the structure of the sealed space and the material conveying path. For example, the inlet 4 can be opened at one end of the side wall and the outlet 5 can be opened at the bottom of the side wall to facilitate the conveying of materials.

[0036] In one feasible embodiment, an inspection port is provided on the side wall away from the discharge port 5, and a sealing door 6 is provided on the inspection port. A locking member 7 is provided between the sealing door 6 and the side wall.

[0037] An inspection window 8 is provided on the sealed door 6.

[0038] In this technical solution, by installing a sealing door 6, a locking element 7, and an inspection window 8 on the side wall, the locking element 7 can tightly lock the sealing door 6 to the side wall during normal equipment production, ensuring the sealing performance of the inspection port and preventing heat loss, exhaust gas escape, or material splashing within the sealed space. When it is necessary to inspect or maintain the interior of the sealed space, the operator can quickly open the sealing door 6 by unlocking the locking element 7 without disassembling the entire discharge hood, significantly shortening maintenance time and reducing downtime losses. Meanwhile, the inspection window 8 on the sealing door 6 is made of transparent, high-temperature resistant materials (such as tempered glass, high-temperature resistant acrylic, etc.). During equipment operation, the operator can directly observe the material conveying status and the working effect of the nozzles 10 within the sealed space through the inspection window 8 without opening the sealing door 6, achieving real-time monitoring of the interior of the discharge hood.

[0039] Understandably, the locking element 7 can be a quick-release type or a bolt type to ensure balanced force and sealing after locking.

[0040] Understandably, the sealing door 6 and the side wall can be connected by hinges, pivots, etc., to facilitate the smooth opening and closing of the sealing door 6. At the same time, a high-temperature resistant sealing gasket can be set on the contact surface between the sealing door 6 and the side wall to further improve the sealing performance.

[0041] In one feasible embodiment, an installation port is provided on the side wall, and a mounting base 9 is provided on the installation port. A nozzle 10 is rotatably provided on the mounting base 9, and the output direction of the nozzle 10 is towards the sealed space.

[0042] The nozzle 10 is a dual-media nozzle.

[0043] In this technical solution, a mounting base 9 is installed on the side wall, and a nozzle 10 is rotatably mounted on the mounting base 9. The output direction of the nozzle 10 is towards the sealed space. The nozzle 10 is a dual-media nozzle. When it is necessary to moisturize or enhance the aroma of the material in the sealed space, two different media can be introduced into the sealed space through the two channels of the dual-media nozzle. At the same time, since the nozzle 10 is rotatably mounted on the mounting base 9, the operator can directly adjust the output angle of the nozzle 10 from outside the discharge hood without opening the sealing door 6 or stopping the machine, thus controlling the position of the media spray and achieving uniform spraying of the material.

[0044] It is understandable that the rotatable connection between the nozzle 10 and the mounting base 9 can be achieved through structures such as bearings and rotary joints, ensuring the flexibility of adjusting the angle of the nozzle 10.

[0045] In one feasible embodiment, an illumination element 11 is provided on the side wall and on one side of the sealing door 6, the illumination element 11 being used to illuminate the sealed space.

[0046] In this technical solution, by installing a lighting element 11 on the side wall, the inside of the discharge hood can be illuminated, making it easier to observe the internal state of the discharge hood during the production process.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
