Description

Technical Field

[0001] The present application relates to the technical field of pneumatic conveying, and in particular to a gasification device in a pneumatic conveying silo pump. Background Art

[0002] The vaporization device within a pneumatic conveying silo pump is a critical component in the system. Air enters the silo pump through an air inlet pipe and diffuses within it. When the silo pump is full, the gas is able to escape through the gaps between the multiple vaporization plates, achieving vaporization. In practice, the vaporization device within a pneumatic conveying silo pump must accommodate materials of varying particle sizes. Traditional vaporization plates have fixed gaps, so the flow of larger particles can easily clog the plates, impacting subsequent vaporization.

[0003] Current pneumatic conveying silo pump gasification devices use a fixed gap for gas fluidization during the gasification process. Changes in gas flow rate or material size can lead to poor gas fluidization. Therefore, a pneumatic conveying silo pump gasification device with self-adjustable fluidization gap is urgently needed.

[0009] Preferably, the sizes of the through holes on the vaporization plate increase sequentially from top to bottom, so that the vaporization plates are lifted sequentially from top to bottom by the air pressure; or, the vaporization plates are lifted simultaneously by the air pressure.

[0010] Preferably, adjacent vaporization plates are vertically elastically connected via a plurality of elastic members, and the plurality of elastic members are evenly distributed along the circumferential direction of the vaporization plates.

[0011] Preferably, adjacent vaporization plates are vertically guided and slidably engaged with each other through a plurality of guide members uniformly arranged along the circumferential direction.

[0012] Preferably, in two adjacent vaporization plates, the guide member is fixedly mounted on one of the vaporization plates and slides through a corresponding guide hole on the other vaporization plate; the elastic member is a spring, which is sleeved on the guide member, and the two ends of the spring respectively abut against the guide member and the vaporization plate on which the guide hole is set.

[0013] Preferably, among any three consecutive vaporization plates, the outer contour size of the top vaporization plate is less than or equal to the size of the through hole in the center of the bottom vaporization plate, so that the guide member between the two top vaporization plates corresponds to the through hole of the bottom vaporization plate.

[0014] Preferably, the guide member is a bolt, which includes a screw and a nut; the bolt passes through the guide hole on one of the vaporization plates and is fastened to the other adjacent vaporization plate through the screw, so that the guide hole and the optical axis section of the screw are slidably matched; the spring is sleeved on the optical axis section and is respectively abutted against the nut and the vaporization plate on which the guide hole is set through its two ends.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] By elastically connecting multiple gasification plates and changing the air pressure below the gasification device in the pneumatic conveying silo pump, the gap between adjacent gasification plates can be adjusted in real time.

[0022] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] In the description of this application, it should be noted that for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, the directions and positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of this application.

[0024] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0025] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0026] One of the preferred embodiments of this application is as follows: Figures 1 to 3As shown, a gasification device within a pneumatic conveying silo pump includes multiple gasification plates 1. The multiple gasification plates 1 are stacked one above the other, with the bottom gasification plate 1 fixed to the bottom of the silo pump 5. Except for the top gasification plate 1, the remaining gasification plates 1 are provided with interconnected through-holes 100. The gasification plates 1 are vertically elastically connected to each other so that the multiple gasification plates 1 are tightly attached to each other under the action of elastic force, sealing the bottom of the silo pump 5. During gasification, air is ventilated to the bottom of the silo pump 5, causing at least one gasification plate 1 to lift under the action of air pressure, thereby creating a ventilation gap 120 between at least one pair of adjacent gasification plates 1 for ventilation to the top of the silo pump 5.

[0027] It should be known that the specific structure and working principle of the silo pump 5 are well known to those skilled in the art, so they will not be elaborated on in detail here. The lower part of the silo pump 5 is an elliptical head 4. The gasification device of the present application can be installed at the connection position between the elliptical head 4 and the silo body, so that the silo pump 5 forms a sealed cavity in the lower area of the elliptical head 4 through the multiple sealed gasification plates 1 of the gasification device. An air inlet pipe 41 for ventilation is provided at the bottom of the elliptical head 4. When gas fluidization is required in the silo pump 5, air can be ventilated into the elliptical head 4 through the air inlet pipe 41. As the air pressure inside the elliptical head 4 gradually increases, at least one gasification plate 1 can be lifted so that a ventilation gap 120 can be formed between at least one pair of gasification plates 1. In addition, the outlet direction of the ventilation gap 120 is horizontal, which can improve the divergence of gas fluidization.

[0028] At the same time, through the elastic connection structure between the vaporization plates 1 of the present application, when the demand for gas fluidization increases, the air intake of the air intake pipe 41 can be increased, and multiple vaporization plates 1 can be lifted to form multiple ventilation gaps 120. Compared with traditional methods, this embodiment elastically connects multiple vaporization plates 1, and the number of ventilation gaps 120 between adjacent vaporization plates 1 can be adjusted in real time by changing the air pressure below the vaporization device in the pneumatic conveying silo pump. When the vaporization device in the pneumatic conveying silo pump stops working, the multiple vaporization plates 1 can automatically mate tightly to prevent impurities from entering the vaporization device in the pneumatic conveying silo pump and causing blockage.

[0029] In this embodiment, Figure 1 As shown, the vaporization plate 1 can have various specific shapes, such as circular or regular polygonal. Generally, the cross-section of the silo pump 5 is circular, so a circular shape is preferably used for the vaporization plate 1. Multiple vaporization plates 1 can be aligned along the center of the end surface, and the sizes of the multiple vaporization plates 1 increase sequentially from top to bottom in the stacking order. When the multiple vaporization plates 1 are raised to form multiple ventilation gaps 120, the gas outlets of the ventilation gaps 120 can be spaced apart radially along the vaporization plate 1, thereby ensuring uniform gas fluidization.

[0030] It should be noted that the specific number of gasification plates 1 can be determined according to the number of ventilation gaps 120 required; for example Figure 1 As shown, a maximum of three ventilation gaps 120 need to be evenly distributed along the radial direction of the vaporization plate 1, so the number of vaporization plates 1 is four. The four vaporization plates 1, from top to bottom, can be the first vaporization plate, the second vaporization plate, the third vaporization plate, and the fourth vaporization plate; the fourth vaporization plate needs to be fixedly installed to support the vaporization plate 1 above it. A ventilation gap 120 can be formed between the first and second vaporization plates, a ventilation gap 120 can be formed between the second and third vaporization plates, and a ventilation gap 120 can also be formed between the third and fourth vaporization plates.

[0031] It should be understood that the multiple ventilation gaps 120 formed between the multiple vaporization plates 1 can be distributed at equal intervals or at non-equal intervals in the radial direction of the vaporization plate 1. In order to ensure uniform distribution of the fluidizing gas, in this embodiment, the multiple ventilation gaps 120 are preferably distributed at equal intervals along the radial direction.

[0032] In this embodiment, to ensure that the vaporization plate 1 can be lifted by air pressure, through holes 100 are provided in the remaining vaporization plates 1 other than the topmost. This allows the air pressure to flow through the through holes 100 and exert pressure on at least the topmost vaporization plate 1 when the air inlet pipe 41 vents air to the lower portion of the silo pump 5, thereby lifting the vaporization plate 1. The through holes 100 can be arranged in various ways based on the method used to lift the vaporization plate 1. For ease of understanding, two specific examples will be used to provide a detailed description.

[0033] Example 1: The through holes 100 on the vaporization plate 1 have the same size and are aligned with each other, so that the vaporization plate 1 is lifted up from top to bottom in sequence by air pressure.

[0034] Specifically, except for the topmost vaporization plate 1, the remaining vaporization plates 1 can have through holes 100 of equal size at their center positions. The through holes 100 can be circular or of other shapes. For ease of description, circular holes are preferred in this embodiment. When air is ventilated into the elliptical head 4, the gas will exert pressure on the topmost vaporization plate 1 along the connected through holes 100, thereby driving the topmost vaporization plate 1 to lift up first. If the pressure generated by the gas pressure is too high and the ventilation gap 120 created by the lifting of the topmost vaporization plate 1 cannot meet the release requirements, the topmost vaporization plate 1 will lift the lower vaporization plates 1 by forming an elastic member 2 or a fastening structure to increase the number of ventilation gaps 120 until the amount of air released from all ventilation gaps 120 is balanced with the amount of air entering the elliptical head 4.

[0035] Example 2: The sizes of the through holes 100 on the vaporization plate 1 increase sequentially from top to bottom, so that the vaporization plate 1 is lifted sequentially from top to bottom by the air pressure; or, the vaporization plate 1 is lifted simultaneously by the air pressure.

[0036] Specifically, the process of sequentially lifting the vaporization plates 1 is essentially the same as in Example 1 above. The case where multiple vaporization plates 1 are lifted simultaneously will be analyzed in detail below. It should be understood that when a vaporization plate 1 is lifted, it must overcome its own gravity and the elastic force between adjacent vaporization plates 1, and the pressure F exerted on the vaporization plate 1 is equal to pressure P / contact area S. Therefore, it is only necessary to adjust the pressure contact area S between each vaporization plate 1 and the air pressure until the forces acting on each vaporization plate 1 are balanced under the same pressure. Consequently, for different air pressure conditions, the degree of opening of the ventilation gap 120 formed between each vaporization plate 1 will vary.

[0037] It is understandable that both of the above two examples can meet the needs of this application. However, considering the weight of the structure, this embodiment preferably adopts the above two examples for the structure of the vaporization plate 1, and each vaporization plate 1 can be lifted in sequence.

[0038] In this embodiment, in order to ensure the stability of the vaporization plate 1 when it is lifted, a guide member 3 needs to be provided between the vaporization plates 1. There are many ways to arrange the guide member 3; Figure 2 and Figure 3 As shown, a guide member 3 may be provided between two adjacent vaporization plates 1. That is, the guide member 3 is fixedly mounted on one of the two adjacent vaporization plates 1 and slides through the corresponding guide hole 110 provided on the other vaporization plate 1. Alternatively, the guide member 3 may be provided on the bottommost fixed vaporization plate 1, with the remaining vaporization plates 3 slidingly engaging with the guide member 3. However, considering the arrangement of the vaporization plates 1, in this embodiment, the guide member 3 is preferably provided between two adjacent vaporization plates 1.

[0039] It should be known that there are many specific structures of the guide member 3, which can be a guide pin or can be guided by a fastener. For ease of understanding, the following will be described in detail using the guide member 3 formed by a fastener as an example.

[0040] like Figures 1 to 3 As shown, the guide member 3 is a bolt comprising a screw and a nut. The screw passes through a guide hole 110 in one vaporizer plate 1 to securely connect it to the adjacent vaporizer plate 1, such that the guide hole 110 and the optical axis of the screw slidably fit together. The screw and the other vaporizer plate 1 can be secured by threading the threaded section of the screw into the threaded hole provided in the vaporizer plate 1. Alternatively, the threaded section, once secured to the threaded hole, can be further tightened using a nut.

[0041] It should be noted that, in order to ensure the guiding stability between the vaporization plates 1 , there are multiple guide members 3 between adjacent vaporization plates 1 , and the multiple guide members 3 can be evenly distributed along the circumferential direction of the vaporization plate 1 .

[0042] In this embodiment, in order to avoid the installation of the guide member 3 between adjacent vaporization plates 1 from interfering with other vaporization plates 1, Figures 1 to 3 As shown, among any three consecutive vaporization plates 1 , the outer contour size of the uppermost vaporization plate 1 can be designed to be smaller than or equal to the size of the central through hole 100 of the lowermost vaporization plate 1 , so that the guide member 3 between the two upper vaporization plates 1 corresponds to the through hole 100 of the lowermost vaporization plate 1 .

[0043] In this embodiment, Figures 1 to 4 As shown, the elastic connection between the vaporization plates 1 is mainly achieved by providing elastic members 2 for vertical elastic connection. In order to ensure the stability of the force applied to the vaporization plates 1, adjacent vaporization plates 1 can be connected by multiple elastic members 2, which are evenly distributed along the circumference of the vaporization plates 1.

[0044] It should be noted that the specific structure and operating principle of the elastic member 2 are well known to those skilled in the art and will not be elaborated on in detail here. Common elastic members 2 include springs and shrapnel. There are many specific installation methods for the elastic member 2. For ease of understanding, the following will provide a detailed description using two specific examples.

[0045] Specific example 1: Figure 4 As shown, aligned mounting grooves 101 can be provided on the opposing end surfaces of two adjacent vaporization plates 1. The elastic member 2 can be directly installed in the mounting grooves 101 and connected to the two vaporization plates 1 at both ends. In this example, the elastic member 2 can be a spring or a spring, and the specific selection can be made based on the actual needs of those skilled in the art.

[0046] Specific Example 2: The elastic member 2 is a spring, which is sleeved onto the guide member 3. The two ends of the spring respectively abut against the guide member 3 and the vaporization plate 1 provided with the guide hole 110. For example, if the guide member 3 is a fastener, the spring can be sleeved onto the optical axis of the screw and abut against the nut and the vaporization plate 1 provided with the guide hole 110 at its two ends.

[0047] It is understood that both of the above-mentioned specific examples can meet the requirements of this application. Considering that specific example 2 can be directly installed according to the configuration of the guide member 3, specific example 2 is preferably used in this embodiment for the installation of the elastic member 2. It should be noted that in order to prevent the ventilation gap 120 from opening too much, the optical axis section of the screw can also be configured as a stepped shaft. Therefore, when the screw is engaged with the guide hole 110 through the stepped shaft, the relative sliding distance between the stepped shaft and the guide hole 110 can be limited, thereby limiting the maximum opening of the ventilation gap 120.

[0048] In this embodiment, Figure 1 As shown, in order to prevent the airflow entering the elliptical head 4 from directly impacting the vaporizer plate 1 and causing increased corrosion of the vaporizer plate 1, a ceramic baffle 300 can be fixedly installed downward from the middle of the uppermost vaporizer plate 1 to correspond to the airflow inlet pipe 41. The end surface size of the ceramic baffle 300 is significantly larger than the cross-sectional size of the airflow inlet pipe 41. This allows the airflow entering the elliptical head 4 from the airflow inlet pipe 41 to be dispersed to the surrounding area after flowing to the ceramic baffle 300, thereby reducing the impact on the vaporizer plate 1.

[0049] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. These changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
