Description

Technical Field

[0001] This application relates to the field of drying tower technology, and more particularly to a material handling device for drying towers. Background Technology

[0002] Industrial waste gas fermentation to produce ethanol is a new technology that uses carbon monoxide as a carbon source to produce ethanol through microbial fermentation. After distillation to extract ethanol, the fermentation wastewater contains a certain amount of microbial protein, which greatly increases the difficulty of wastewater treatment. At the same time, the microbial protein in the wastewater has a single composition and high crude protein content, making it a high-value-added protein feed that can be widely used in aquaculture and livestock feeding. Furthermore, microbial protein powder can replace a portion of fishmeal in the feed industry to reduce the dependence on high-grade protein feed for marine fish. Therefore, fermentation wastewater can be used to produce protein powder, which can be obtained through processes such as centrifugal concentration and drying in a drying tower.

[0003] However, during the operation of the drying tower, a large amount of clumped protein powder will accumulate in the air outlet pipe of the drying tower after a long period of operation, which is difficult to clean and seriously affects the normal operation of the drying system. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a material handling device for a drying tower, which can reduce the risk of material accumulation clogging the air outlet pipe, and at the same time, can realize the recycling of material accumulation.

[0027] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0028] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0029] The following is in conjunction with the appendix Figure 1-2This application describes a material handling apparatus 100 for a drying tower according to some embodiments.

[0030] The material handling device 100 for the drying tower can be applied to the drying tower 200, such as... Figure 1 As shown, the drying tower 200 is equipped with an air outlet duct 210. In order to meet the subsequent process settings, the vertical heights of the inlet and outlet ends of the air outlet duct 210 are different. Therefore, a lifting section 211 is provided in the middle of the air outlet duct 210. Under long-term operation, a large amount of agglomerated protein powder (the accumulated material described in this application) is easily accumulated at the position of the lifting section 211 of the air outlet duct 210. The accumulated material is difficult to clean and seriously affects the normal operation of the drying system.

[0031] In response, this application proposes a material handling device 100 for a drying tower. For example... Figure 2 As shown, the material handling device 100 for the drying tower includes: a vibrating hammer 10, a cyclone dust collector 30, a bag filter dust collector 40, a discharge pipe 90, and an induced draft fan 50.

[0032] A vibratory hammer 10 is installed inside an air outlet 210. The air outlet 210 has a material accumulation outlet 20. A cyclone dust collector 30 has a first air inlet 31, a first air outlet 32, and a first dust collection port 33. The first air inlet 31 is connected to the material accumulation outlet 20. The first air outlet 32 ​​is equipped with an induced draft fan 50. The first dust collection port 33 is connected to the discharge pipe 90. A bag filter 40 is installed between the first air outlet 32 ​​and the induced draft fan 50. The bag filter 40 has a second air inlet 41 and a second air outlet 42. The second air inlet 41 is connected to the first air outlet 32, and the second air outlet 42 is connected to the induced draft fan 50.

[0033] It is understandable that the vibratory hammer 10 includes, but is not limited to, pneumatic vibratory hammers, electromechanical vibratory devices, and electromagnetic vibratory hammers. Pneumatic vibratory hammers use compressed air as power to generate shock waves by impacting the base plate through a piston, such as the K-series pneumatic hammers (K160G and other models). Electromechanical vibratory devices rely on a motor to drive the mechanical structure to achieve periodic impacts. They have a simple structure and are easy to maintain. Electromagnetic vibratory hammers use electromagnetic force to drive the hammer head to move. They have a fast response speed, but the impact force is relatively small and they are suitable for light working conditions.

[0034] In actual use, hot air flows through the outlet duct 210, and the vibrating hammer 10 vibrates to mix the accumulated material in the outlet duct 210 with the hot air and enter the cyclone dust collector 30 through the first air inlet 31. This reduces the risk of the accumulated material clogging the outlet duct 210. Then, the centrifugal force of the cyclone dust collector 30 sends the solid material to the discharge pipe 90. That is, the cyclone dust collector 30 performs primary dust removal on the mixture of accumulated material and hot air. Then, the filtered hot air enters the bag filter 40 through the second air inlet 41. The bag filter 40 performs secondary dust removal on the mixture of accumulated material and hot air after the primary dust removal. In this way, the air exiting the outlet duct 210 can be purified and dust removed, thereby reducing pollution to the atmospheric environment.

[0035] Meanwhile, the solid material is sent to the discharge pipe 90 by the centrifugal action of the cyclone dust collector 30, which enables the recycling of the material.

[0036] According to the embodiment of this application, the material handling device 100 for a drying tower uses a vibrating hammer 10 to discharge the accumulated material in the air outlet duct 210 to a cyclone dust collector 30 for primary dust removal. Then, the centrifugal force of the cyclone dust collector 30 sends the accumulated material to the discharge pipe 90. This reduces the risk of the accumulated material clogging the air outlet duct 210 and enables the recovery of the accumulated material. The air after primary dust removal enters a bag filter 40 for secondary dust removal and is finally discharged from the outlet of the induced draft fan 50. This achieves purification and dust removal of the air outlet from the air outlet duct 210, thereby reducing pollution to the atmospheric environment.

[0037] In some embodiments, such as Figure 2 As shown, the bag filter 40 is provided with a second dust collection port 43, which is connected to the discharge pipe 90. This facilitates the collection of the powdery solid material filtered by the bag filter 40 through the second dust collection port 43 to the discharge pipe 90, thereby realizing the recycling of the accumulated material.

[0038] In some embodiments, such as Figure 2 As shown, the material handling device 100 for the drying tower also includes a compressed air pipe 60, which is provided with a compressed air inlet and a compressed air outlet. The compressed air inlet is adapted to receive compressed air, and the compressed air outlet is open toward the filter bag of the bag filter 40.

[0039] In this way, compressed air can be injected into the compressed air pipe 60 to blow the protein powder particles on the filter bag of the bag dust collector 40 to the second dust collection port 43, and then collected by the discharge pipe 90.

[0040] In some embodiments, the material handling device 100 for the drying tower further includes an electronic pulse valve disposed at the compressed air inlet.

[0041] This facilitates the control of compressed air intake through electronic pulse valves. Electronic pulse valves are compact, occupy little space, and are easy to install and maintain. Electromagnetic pulse valves have a rapid response and can accurately control the opening and closing of airflow. The design and materials of electromagnetic pulse valves give them a long service life, reducing the frequency of replacement and maintenance.

[0042] In some embodiments, such as Figure 2 As shown, the material handling device 100 for the drying tower also includes a guide tube 70, which is provided with an inlet and an outlet. The inlet is connected to the material outlet 20, and the outlet is connected to the first air inlet 31.

[0043] In this way, the material outlet 20 can be connected to the first air inlet 31 through the guide tube 70, so as to facilitate the flow of the mixture of material and hot air into the cyclone dust collector 30. In order to ensure the centrifugal dust removal function of the cyclone dust collector 30, the material outlet enters tangentially along the cyclone dust collector 30 to ensure the realization of the centrifugal dust removal function of the cyclone dust collector 30.

[0044] In some embodiments, such as Figure 2 As shown, the inner diameter of the guide tube 70 gradually decreases in the direction from the inlet to the outlet.

[0045] In this way, the flow rate of the mixture of accumulated material and hot air entering the first air inlet 31 can be controlled, so as to avoid the amount of the mixture of accumulated material and hot air entering being too large and exceeding the load capacity of the cyclone dust collector 30, which would lead to damage to the cyclone dust collector 30.

[0046] In some embodiments, such as Figure 2 As shown, the material handling device 100 for the drying tower further includes a pneumatic regulating butterfly valve 81, which is disposed inside the guide tube 70 and located between the inlet and outlet. Thus, the pneumatic regulating butterfly valve 81 can control the opening and closing of the passage within the guide tube 70.

[0047] In some embodiments, such as Figure 2 As shown, the material handling device 100 for the drying tower also includes a control device and a level gauge 82. The level gauge 82 is installed inside the guide tube 70 and is located between the feed inlet and the pneumatic regulating butterfly valve 81. The level gauge 82 is used to detect the height of the accumulated material on the pneumatic regulating butterfly valve 81 when the pneumatic regulating butterfly valve 81 is closed. Both the level gauge 82 and the pneumatic regulating butterfly valve 81 are electrically connected to the control device.

[0048] Understandably, when the pneumatic regulating butterfly valve 81 is closed, material will accumulate on it. At this time, the level gauge 82 can detect the height of the accumulated material on the pneumatic regulating butterfly valve 81 and then send this height information to the control device. The control device can then control the pneumatic regulating butterfly valve 81 to open or close based on this height information to avoid the accumulated material on the pneumatic regulating butterfly valve 81 becoming too high and damaging it.

[0049] In some embodiments, the material handling device 100 for the drying tower further includes a first discharge valve disposed at the first dust collection port 33. Thus, the opening and closing of the first dust collection port 33 can be controlled by the first discharge valve.

[0050] In some embodiments, the material handling device 100 for the drying tower further includes a second discharge valve disposed at the second dust collection port 43. Thus, the opening and closing of the second dust collection port 43 can be controlled by the second discharge valve.

[0051] In some embodiments, the material handling device 100 for the drying tower further includes an air purifier, the inlet of which is connected to the outlet of the induced draft fan 50.

[0052] In this way, the hot air discharged from the outlet of the exhaust fan 50 can be purified by an air purifier. For example, the air purifier can be equipped with a filter to intercept larger particulate matter and reduce the possibility of it carrying odors, or the air purifier can be equipped with activated carbon to adsorb odor molecules by utilizing the rich microporous structure of activated carbon. Thus, the air purifier can reduce impurities and odors in the hot air, thereby reducing the pollution of the exhaust gas to the atmospheric environment.
