Description

Technical Field

[0001] This utility model belongs to the technical field of unloading equipment, specifically relating to an anti-sticking unloader. Background Technology

[0002] Unloaders are widely used in industries such as cement, metallurgy, mining, and petrochemicals, primarily serving as material conveyors and airlocks. Traditional unloaders typically consist of a star rotor and a housing. Their working principle involves rotating the star rotor to drive the material discharge, while a sealing design prevents air leakage.

[0003] However, in practical applications, traditional unloaders often fail to effectively remove material adhering to the impeller during the unloading process, especially for sticky materials. Sticky materials tend to adhere to the impeller blades of the unloader, and as the unloading process continues, they gradually accumulate and form deposits, causing the impeller blades to rotate poorly and thus affecting the normal unloading of materials.

[0004] The aforementioned problems not only reduce the working efficiency of the unloader, but also aggravate equipment wear and tear, increase equipment maintenance costs, and require frequent manual cleaning, which seriously affects production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an anti-sticking unloader that solves the technical problem that existing unloaders cannot effectively remove adhering sticky materials.

[0006] This utility model discloses an anti-sticking unloader, comprising:

[0007] The shell has a hollow interior forming a rotating cavity, and has a feed inlet and a discharge outlet, both of which are connected to the rotating cavity.

[0008] A star-shaped rotor is arranged in the rotating cavity, including...

[0009] The main shaft is coaxially arranged within the rotating cavity, with both ends extending outside the housing.

[0011] At least three arc-shaped plates are arranged between the side end plates and connected end to end around the main shaft to form a discharge trough and a drying chamber;

[0012] Two sealing structures are respectively disposed between the end faces of the side end plate and the rotating cavity, and are sleeved on the outside of the main shaft to form an annular transfer cavity;

[0016] The side end plate has several through holes arranged around the main shaft, which are used to connect the drying chamber and the transfer chamber.

[0017] This application forms a discharge trough and a drying chamber by setting an arc-shaped plate between the side end plates and arranging them end to end around the main shaft. This allows hot flue gas to be introduced to dry the material, thereby reducing the stickiness of the material and playing an anti-sticking role.

[0059] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0060] First, it should be noted that some directional terms used in the following description to clearly illustrate the technical solution of this utility model, such as the terms "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," are all derived from the normal orientation of the components in the anti-stick unloader. They are only used to facilitate the description of this utility model and simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0061] In this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0062] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0063] Example:

[0064] like Figures 1-5 As shown in the figure, this application discloses an anti-stick unloader for material conveying and airlocking. Its specific structure includes: a housing 1, a star rotor 2, two sealing structures 3, two supporting structures 5, and a drive mechanism 6.

[0065] The shell 1 serves as the main structure, with a hollow interior forming a rotating cavity 11 for accommodating the star rotor 2 and conveying materials. It also has an inlet 12 and an outlet 13, both of which are connected to the rotating cavity 11 to ensure the smooth entry and exit of materials.

[0066] Preferably, the inlet 12 and the outlet 13 are respectively located on the upper and lower sides of the housing 1, which allows the material to smoothly enter the rotating cavity 11 from top to bottom, and smoothly discharge from the outlet 13 after conveying and processing.

[0067] The star-shaped rotor 2 is arranged in the rotating cavity 11, including:

[0068] The main shaft 21 is coaxially arranged inside the rotating cavity 11, and its two ends extend out of the housing 1;

[0069] Two side end plates 22 are fitted onto the main shaft 21 and are located on both sides of the feed inlet 12, respectively, and are in contact with the peripheral wall of the rotating cavity 11, thus playing a role in sealing and supporting.

[0070] At least three arc-shaped plates 23 are arranged between the side end plates 22 and are connected end to end around the main shaft 21 to form the unloading trough 24 and the drying chamber 25.

[0071] For example, the arc plate 23 is provided with six pieces and has a parabolic cross-section, which makes the concave surface without corners, thus improving the material conveying efficiency.

[0072] Specifically, the unloading trough 24 is formed by the inner concave surfaces of two side end plates 22 and an arc plate 23, and is used to accommodate and transport materials. It is also in contact with the peripheral wall of the rotating cavity 11, thereby playing a role in locking the air.

[0073] Specifically, the drying chamber 25 is formed by the cooperation of two side end plates 22 and the convex surfaces of all the arc plates 23, and is used to dry the material by introducing hot flue gas, thereby reducing the stickiness of the material and thus playing an anti-sticking role.

[0074] Two sealing structures 3 are respectively located between the end faces of the side end plate 22 and the rotating cavity 11, and are sleeved on the outside of the main shaft 21 to form an annular transfer cavity 31, which ensures the stable introduction and discharge of hot flue gas, while preventing material leakage and air pollution.

[0075] Two conveying pipes 4 are respectively located on both sides of the housing 1 and connected to the adjacent transfer chamber 31 for the input and discharge of hot flue gas, ensuring the stability of flue gas conveying.

[0076] Two support structures 5 are respectively located on both sides of the housing 1 and are rotatably connected to the main shaft 21, providing stable support and a rotation platform for the main shaft 21.

[0077] The drive mechanism 6 is mounted on a support structure 5 and is connected to the main shaft 21 for transmission. It provides the power source to drive the star rotor 2 to rotate, ensuring the smooth conveying and handling of materials.

[0078] The side end plate 22 has several through holes 221 arranged around the main shaft 21. The through holes 221 are used to connect the drying chamber 25 and the transfer chamber 31, so as to ensure that the hot flue gas can be smoothly input into the drying chamber 25 from one transfer chamber 31 and then output from the drying chamber 25 to another transfer chamber 31, thereby ensuring that the drying is not disturbed by the rotation of the star rotor 2.

[0079] For example, six through holes 221 are provided and are circular, which allows flue gas to enter and exit smoothly, ensures stable airflow, and improves the drying effect.

[0080] The above technical solution works as follows:

[0081] When conveying materials, the drive mechanism 6 drives the star rotor 2 to rotate in the rotating cavity 11 of the housing 1. Then, the viscous material is put in from the feed port 12 and falls into the rotating cavity 11 and is in a discharge trough 24. Then, as the star rotor 2 rotates, the discharge trough 24 is aligned with the discharge port 13 and is smoothly discharged from the discharge port 13 to the outside of the device.

[0082] During the drying and anti-sticking process, hot flue gas is introduced into a conveying pipeline 4, then into a transfer chamber 31, and then into the drying chamber 25 through the through hole 221. The hot flue gas heats the arc plate 23, and then dries the sticky material in the unloading trough 24 through heat transfer, thereby reducing the stickiness of the material and thus playing an anti-sticking role. Then the cooled hot flue gas is output from the drying chamber 25 to another transfer chamber 31, and finally transported out of the device through another conveying pipeline 4.

[0083] This application forms a discharge trough 24 and a drying chamber 25 by setting an arc-shaped plate 23 between the side end plates 22 and arranging it end to end around the main shaft 21. This allows hot flue gas to be introduced to dry the material, thereby reducing the stickiness of the material and playing an anti-sticking role. It also realizes waste heat recovery and improves the energy-saving and environmental protection effect. Furthermore, an annular transfer chamber 31 is formed by the sealing structure 3, and combined with the through hole 221 connecting the drying chamber 25 and the transfer chamber 31, the stable introduction and discharge of hot flue gas is ensured, while preventing material leakage and air pollution.

[0084] In some embodiments, such as Figure 4 As shown, the star rotor 2 includes: a sleeve 26, which is detachably sleeved on the main shaft 21, and side end plates 22 are fixedly sleeved at both ends.

[0085] By setting the sleeve 26, the structural strength of the star rotor 2 is improved, its resistance to deformation is enhanced, its structural stability is improved, and it is easier to assemble and produce, reducing manufacturing difficulty.

[0086] Based on the above embodiments, such as Figure 2 As shown, the star rotor 2 includes two sets of reinforcing plates 27, which are respectively disposed at both ends of the sleeve 26 and connected to the adjacent side end plates 22; wherein, each set of reinforcing plates 27 has multiple plates, which are evenly arranged around the sleeve 26.

[0087] By setting the reinforcing plate 27, the strength and stability of the connection between the sleeve 26 and the side end plate 22 can be significantly enhanced, thereby improving the load-bearing capacity and resistance to external loads of the entire structure.

[0088] In some embodiments, such as Figure 1 As shown, the sealing structure 3 includes two sealing units 32 and two inflation lines 34, which are configured as follows:

[0089] Two sealing units 32 are coaxially sleeved outside the through hole 221 and are arranged at intervals to form an annular sealing cavity 33;

[0090] An inflation line 34 is provided on the housing 1 and communicates with the sealing cavity 33. It is used to fill the sealing cavity 33 with gas (usually air or inert gas such as nitrogen) to increase the pressure inside the sealing cavity 33.

[0091] When the unloader starts working, gas is injected into the sealing cavity 33 through the air filling pipe 34, which makes the pressure in the sealing cavity 33 greater than the pressure in the transfer cavity 31. This will suppress the leakage of hot flue gas from the inlet 12 and outlet 13 in the transfer cavity 31, thus achieving the sealing effect.

[0092] The above design ensures the sealing of the unloader during operation, preventing the material from being contaminated by flue gas.

[0093] Based on the above embodiments, such as Figure 1 As shown, the sealing unit 32 includes multiple ring baffles 321, which are arranged in a circular ring structure and are attached to each other, and are alternately arranged on the side end plate 22 and the rotating cavity 11.

[0094] The above design avoids interference caused by the rotation of the side end plate 22, ensures the sealing effect, and has a simple and compact structure that is easy to manufacture and install.

[0095] In this embodiment, as Figure 1 As shown, the sealing structure 3 includes: an annular support 35, which is disposed on the end face of the rotating cavity 11 and rotatably sleeved on the outside of the main shaft 21; wherein, the sealing unit 32 is disposed between the end face of the annular support 35 and the side end plate 22.

[0096] Preferably, the annular support 35 is hollow inside, thereby reducing the overall weight and material costs.

[0097] By setting the annular support 35, the structural strength of the housing 1 is enhanced, the contact area with the main shaft 21 is increased, and the sealing effect and support stability are improved.

[0098] In some embodiments, such as Figure 1 As shown, the support structure 5 includes: a support plate 51, a rotating bearing 52, and multiple support arms 53, which are configured as follows:

[0099] Support plate 51 is used for mounting and securing other components;

[0100] Rotary bearing 52 is mounted on support plate 51 and fitted onto the end of spindle 21 to enable spindle 21 to rotate smoothly on support plate 51 while reducing friction and wear.

[0101] Multiple support arms 53 are disposed between the support plate 51 and the housing 1 and are arranged around the main shaft 21 to fix the support plate 51.

[0102] Through the coordinated action of the aforementioned support plate 51, rotating bearing 52, and multiple support arms 53, a stable and reliable support platform is provided, ensuring that the main shaft 21 can rotate smoothly, while preventing the structure from shaking or tilting during operation, thereby ensuring the stable operation and long-term reliability of the equipment.

[0103] In some embodiments, such as Figure 1 As shown, it also includes a speed detection mechanism 7, which is mounted on another support structure 5 to ensure that the speed of the spindle 21 is accurately monitored and controlled. By being mounted on the support structure 5, the accuracy and reliability of the measurement are improved, providing a strong guarantee for the stable operation of the equipment.

[0104] In this embodiment, as Figure 1 As shown, the rotational speed detection mechanism 7 includes: an L-shaped block 71, a protective cover 72, and a photoelectric sensor 73, which are configured as follows:

[0105] The L-shaped block 71 is located at one end of the main shaft 21 and is used to rotate with the rotation of the main shaft 21. Its L-shaped design can provide a rotation mark that is easily detected by the photoelectric sensor 73.

[0106] The protective cover 72 is mounted on a support plate 51 and covers the end of the main shaft 21. It is used to protect the photoelectric sensor 73 from dust and dirt, and also provides a safe installation environment to ensure that the photoelectric sensor 73 can work stably.

[0107] The photoelectric sensor 73 is mounted on the protective cover 72, and the detection end extends into the protective cover 72 and corresponds to the L-shaped block 71, and is used to detect the rotation of the L-shaped block 71.

[0108] When the L-shaped block 71 rotates with the spindle 21, it periodically blocks the detection end of the photoelectric sensor 73, which causes the electrical signal output by the photoelectric sensor 73 to change. By measuring the frequency and time interval of this change, the rotational speed of the spindle 21 can be accurately calculated.

[0109] The above design enables precise monitoring of the spindle speed 21, which not only improves the performance and safety of the equipment, but also provides strong support for the maintenance and management of the equipment.

[0110] In some embodiments, such as Figure 1 As shown, the drive mechanism 6 includes: a support frame 61, a motor 62, and a coupling 63, which are configured as follows:

[0111] The support frame 61 is mounted on a support plate 51 and is used to install and fix other components;

[0112] The motor 62 is mounted on the support frame 61 and serves as a power source, driving the main shaft 21 to rotate.

[0113] One end of the coupling 63 is sleeved with the end of the main shaft 21, and the other end is sleeved with the drive shaft of the motor 62, which ensures synchronous rotation between the motor 62 and the main shaft 21.

[0114] The above design enables the drive of the spindle 21, which not only ensures the normal operation of the equipment, but also improves the reliability and stability of the equipment.
