Description

Technical Field

[0001] This utility model relates to the field of exhaust structure technology, and in particular to an exhaust device for wet granulation. Background Technology

[0002] In wet granulation processes, the design of the exhaust structure directly affects granulation efficiency and equipment operability. Current technologies generally employ vertical exhaust channels in wet granulation equipment, resulting in a relatively high overall exhaust system height. This makes it difficult to accommodate the material discharge space requirements of IBC containers, often necessitating adjustments to the equipment layout or the addition of auxiliary devices, increasing operational complexity. Furthermore, traditional exhaust breathers have a small cross-sectional area, low exhaust efficiency, and often employ fixed connection structures with complex internal components, making cleaning and maintenance difficult and prone to material residue or cross-contamination. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a wet granulation discharge device to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an exhaust device for wet granulation, comprising:

[0005] An exhaust channel is provided with an angled section on the inner wall of the exhaust channel along the exhaust direction. The angled section extends from the exhaust inlet of the exhaust channel to the exhaust outlet. The exhaust channel is also connected to a wet granulation machine.

[0006] An exhaust breather is provided, which is connected to the outlet end of an exhaust channel and is detachably connected to the exhaust channel. The exhaust breather has an exhaust cavity inside and its axial height is adapted to the feeding space of the IBC bucket in the wet granulation process.

[0007] As a further improvement of this utility model: the angle of the oblique angle is 45°.

[0008] As a further improvement of this utility model: the outlet end of the exhaust channel is provided with a flow divider for dispersing airflow, and the flow divider is detachably connected to the exhaust channel.

[0009] As a further improvement of this utility model: the flow divider is provided with guide plates for dispersing airflow at intervals along the circumference.

[0010] As a further improvement of this utility model: a vibrating plate is provided on the exhaust channel, and the exhaust channel is linked with the vibrating plate.

[0011] As a further improvement of this utility model: the exhaust breather is detachably connected to the exhaust channel by means of a snap-fit.

[0012] As a further improvement of this utility model: the cross-sectional area of ​​the exhaust cavity of the exhaust breather is larger than the cross-sectional area of ​​the exhaust channel.

[0013] As a further improvement of this utility model: the exhaust breathing apparatus is provided with a filter, which is detachably connected to the housing of the exhaust breathing apparatus by a thread.

[0014] As a further improvement of this utility model: the exhaust breathing apparatus is also provided with an exhaust pipe, which is connected to the exhaust cavity of the exhaust breathing apparatus.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The exhaust device of this utility model, by setting an angle along the exhaust direction in the exhaust channel, can guide the hot and humid airflow to rise smoothly along a preset path, detect the turbulence between the airflow and the pipe wall, thereby improving exhaust efficiency and avoiding dust backflow or material adhesion caused by airflow turbulence. The exhaust breather and the exhaust channel outlet end are detachably connected, realizing quick disassembly and assembly, greatly simplifying the cleaning and maintenance process. The axial height of the exhaust breather is specially adapted to the IBC barrel unloading space, effectively solving the unloading interference problem caused by the excessive space occupation of traditional vertical exhaust devices. The exhaust cavity set inside the exhaust breather reduces the airflow velocity by increasing the cross-sectional area, and can intercept fine particles through an integrated detachable filter, reducing exhaust gas pollution.

[0017] 2. Setting the inner wall of the exhaust channel at a 45° angle can improve the airflow path. The 45° angle of the exhaust channel can reduce the collision and turbulence between the airflow and the inner wall of the channel, allowing the hot and humid airflow to rise smoothly along the angle, reducing airflow resistance and improving exhaust efficiency. At the same time, the smooth airflow helps to reduce disturbance to the material and reduce the material from adhering to the inner wall of the channel due to airflow turbulence.

[0018] 3. During the granulation process, particles carried by the hot and humid airflow are prone to adhere to the inner wall of the channel due to factors such as humidity and static electricity, which can lead to obstruction of exhaust. After the vibrating plate is linked with the exhaust channel, the mechanical force generated by the high-frequency vibration can effectively break the adhesion between the particles and the channel wall, so that the attached material can fall off in time and prevent the channel from being blocked.

[0027] An embodiment of this utility model provides an exhaust device for wet granulation, including an exhaust channel 2, the inner wall of which is provided with an oblique angle along the material flow direction, the oblique angle extending from the exhaust inlet to the exhaust outlet of the exhaust channel 2, the exhaust channel 2 being connected to a wet granulation machine; and an exhaust breather 1, which is connected to the outlet end of the exhaust channel 2 and is detachably connected to the exhaust channel 2, the exhaust breather 1 having an exhaust cavity, and the axial height of the exhaust breather 1 being adapted to the material feeding space of the IBC tank in the wet granulation process.

[0028] The exhaust device of this utility model, by setting an angle along the exhaust direction in the exhaust channel 2, can guide the hot and humid airflow to rise smoothly along a preset path, detect the turbulence between the airflow and the pipe wall, thereby improving exhaust efficiency and avoiding dust backflow or material adhesion caused by airflow turbulence. The exhaust breather 1 and the outlet end of the exhaust channel 2 are detachably connected, realizing quick disassembly and assembly, greatly simplifying the cleaning and maintenance process. The axial height of the exhaust breather 1 is specially adapted to the IBC barrel unloading space, effectively solving the unloading interference problem caused by the excessive space occupation of traditional vertical exhaust devices. The exhaust cavity set inside the exhaust breather 1 reduces the airflow velocity by increasing the cross-sectional area, and can intercept fine particles through the integrated detachable filter 6, reducing exhaust gas pollution.

[0029] In one embodiment of this invention, the angle of the oblique angle is 45°. In this invention, setting the oblique angle of the inner wall of the exhaust channel 2 to 45° optimizes the airflow path. The 45° oblique angle of the exhaust channel 2 reduces collisions and turbulence between the airflow and the inner wall of the channel, allowing the hot and humid airflow to rise smoothly along the oblique angle, reducing airflow resistance and improving exhaust efficiency. Simultaneously, the stable airflow helps reduce disturbance to the material, minimizing material adhesion to the inner wall of the channel due to airflow turbulence. Furthermore, setting the oblique angle of the exhaust channel 2 to 45° reduces vertical space occupation, lowering the overall height of the exhaust channel 2 and adapting to the limited space of the IBC container.

[0030] In one embodiment of this utility model, a flow divider 5 for dispersing airflow is provided at the outlet end of the exhaust channel 2, and the flow divider 5 is detachably connected to the exhaust channel 2. Further, the flow divider 5 is provided with guide plates 9 for dispersing airflow at intervals along the circumferential direction. When the airflow generated by wet granulation enters the exhaust breather 1, it tends to concentrate in the axial direction, resulting in uneven flow velocity and excessive local pressure. First, the airflow is discharged from the exhaust channel 2 into the exhaust breather 1. Then, the diverter 5 is set at the outlet end of the exhaust channel 2. The airflow is first discharged along the axial direction of the exhaust breather 1. After being diverted by the diverter 5, the airflow along the axial direction of the exhaust breather 1 is divided into airflow along the radial direction of the exhaust breather 1, thus achieving the effect of airflow diversion. The outlet end of the exhaust channel 2 is equipped with a detachable diverter 5 and a guide plate 9, which can disperse the airflow. The diverter 5 and the guide plate 9 can divide the axial airflow into radial airflow, so that the airflow is evenly diffused in the breather, avoiding the problem of particles clogging the filter screen caused by excessive local flow velocity, and extending the service life of the filter screen. At the same time, the diverter 5 is detachably assembled on the exhaust channel 2, which facilitates the periodic cleaning of the accumulated material on the diverter 5 and the guide plate 9, preventing material residue from affecting the diversion effect.

[0031] In one embodiment of this utility model, a vibrating plate 3 is provided on the exhaust channel 2, and the exhaust channel 2 and the vibrating plate 3 are linked. The vibrating plate 3 can be a piezoelectric ceramic vibrating plate 3. During the granulation process, particles carried by the hot and humid airflow are easily adhered to the inner wall of the channel due to factors such as humidity and static electricity, resulting in obstruction of exhaust. After the vibrating plate 3 is linked with the exhaust channel 2, the mechanical force generated by the high-frequency vibration can effectively break the adhesion between the particles and the channel wall, so that the adhered material can be detached in time and the channel can be prevented from being blocked.

[0032] In one embodiment of this utility model, the exhaust respirator 1 is detachably connected to the exhaust channel 2 via a snap-fit ​​8. The snap-fit ​​8 structure simplifies the connection between the respirator and the exhaust channel 2, eliminating the need for tools and allowing for quick installation and disassembly, thus reducing the time and cost of equipment maintenance, repair, and cleaning. When it is necessary to clean the internal filter or maintenance chamber of the exhaust respirator 1, the snap-fit ​​8 connection method can efficiently separate the components, facilitating deep cleaning and maintenance of each part. Alternatively, the exhaust respirator 1 is detachably connected to the exhaust channel 2 via a threaded connection.

[0033] In one embodiment of this invention, the cross-sectional area of ​​the exhaust cavity of the exhaust respirator 1 is larger than that of the exhaust channel 2. When the hot and humid airflow enters the exhaust respirator 1 from the exhaust channel 2, the sudden increase in the channel's cross-sectional area causes a sharp drop in airflow velocity, effectively reducing the impact of the airflow on the internal filter of the respirator and extending the filter's service life. Simultaneously, the diffused airflow is more easily filtered by the filter, significantly improving the efficiency of fine particle interception and reducing exhaust pollution.

[0034] In one embodiment of this utility model, a filter 6 is provided inside the exhaust respirator 1, and the filter 6 is detachably connected to the housing of the exhaust respirator 1 via a thread. The filter is a filter screen, and the threaded connection makes the connection between the filter 6 and the exhaust respirator 1 simple, requiring no tools and allowing for quick installation and disassembly, thus reducing the time and cost of equipment maintenance, repair, and cleaning. When it is necessary to clean the filter screen inside the exhaust respirator 1, the threaded connection can efficiently separate the components, facilitating deep cleaning and maintenance of each part.

[0035] In one embodiment of this utility model, the exhaust breather 1 is further provided with an exhaust pipe 4, which connects to the exhaust cavity of the exhaust breather 1. An electromagnetic valve 7 is also provided on the exhaust pipe 4, which controls the opening and closing of the exhaust pipe 4. When the exhaust breather 1 starts to exhaust, the electromagnetic valve 7 automatically opens to ensure timely and smooth airflow, avoiding exhaust obstruction or system pressure increase due to human operation delays. When the equipment is shut down, under maintenance, or when exhaust is abnormal, the electromagnetic valve 7 can close, effectively blocking the airflow and preventing backflow of waste gas and dust contamination of the granulation chamber, thus ensuring the safety of the equipment and the production environment.

[0036] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
