Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, and in particular to a scraper-type solid feeding equipment. Background Art

[0002] In the fine chemical industry, many reaction processes require the addition of solid materials into a reactor for reaction. However, due to the characteristics of these solid materials and the diversity of reaction processes, there are many problems with the feeding operation. At present, the solid feeding equipment in the existing technology has exposed obvious defects in practical applications, and there is a problem of being unable to accurately control the feeding amount and feeding rate. This results in the feeding operation being difficult to accurately meet the needs of the reaction process in the actual production process. When the feeding amount cannot be effectively controlled, too much or too little material may be added, which in turn affects the progress of the reaction and the quality of the product. The instability or uncontrollability of the feeding rate may cause fluctuations in key parameters such as pressure and temperature in the reactor, and may even cause the reaction to get out of control, causing a safety accident.

DETAILED DESCRIPTION

[0038] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0039] To simplify the drawings, only the parts relevant to the utility model are schematically shown in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0040] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0041] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0042] Reference Figures 1 to 5, which is the first embodiment of the utility model, proposes a scraper-type solid feeding equipment, including a shell 1, a first cavity 101 is provided in the shell 1, the shell 1 also has a feed port 102 and a discharge port 103, and the feed port 102 and the discharge port 103 are completely staggered; the rotating rod 2 is rotatably arranged in the first cavity 101 and coincides with the axis of the shell 1; there are a plurality of scraping members 3, and one end of each of the scraping members 3 is provided on the rotating rod 2, and the scraping members 3 abut against the bottom surface of the first cavity 101.

[0043] In this embodiment, the housing 1 is made of high-strength, corrosion-resistant stainless steel to ensure it will not be damaged by corrosion during long-term use. When the equipment begins operation, the nitrogen protection device is activated to continuously purge nitrogen into the first cavity 101, continuously displacing the air therein. Simultaneously, the oxygen detection device is activated to monitor the oxygen content within the first cavity 101. Excessive oxygen levels can create a risk of explosion due to static sparks during the scraping process. Therefore, it is crucial to ensure that the oxygen content meets safety standards throughout the entire operation. Once the test passes, the release valve is opened, and solid material is fed into the feed port 102. The feed port 102 is located on the upper left side of the housing 1, while the discharge port 103 is located on the lower right side of the housing 1. These two ports are staggered, effectively preventing uncontrolled material outflow. The rotating rod 2 is mounted in the center of the housing 1 to ensure smooth rotation. The length of scraper 3 is slightly smaller than the radius of first cavity 101, ensuring that it does not collide with the inner wall of housing 1 during rotation. As rotating rod 2 rotates, scraper 3 also rotates within first cavity 101, with its bottom in close contact with the bottom surface of first cavity 101, effectively scraping up material accumulated on the bottom surface and promoting its transport.

[0044] The advantage lies in the completely staggered layout of the feed port 102 and the discharge port 103, with the scraper 3 abutting the bottom surface of the first cavity 101. This design not only ensures that the material has sufficient time to be processed and conveyed within the device, preventing short-circuiting of the material outflow, but also ensures that the scraper 3 promptly clears the material from the bottom surface of the first cavity 101, preventing material accumulation. This ensures stable operation of the device and smooth material conveyance, thereby improving its operating efficiency and reliability.

[0045] Furthermore, the plurality of scraping members 3 are evenly distributed along the circumference of the axis of the rotating rod 2 .

[0046] In this embodiment, on the basic device of claim 1, the scrapers 3 are evenly distributed along the circumference of the axis of the rotating rod 2. The installation position of the scrapers 3 ensures that the pushing and cleaning effects of the scrapers 3 on the material are evenly distributed on the bottom surface of the first cavity 101 during the rotation of the rotating rod 2.

[0047] The advantage is that the uniform distribution of scraper elements 3 along the circumference of the axis of the rotating rod 2 allows for more uniform scraping of the bottom surface of the first cavity 101 during operation, preventing localized accumulation of material or incomplete cleaning. Furthermore, the even distribution of scraper elements 3 ensures more balanced force distribution across the entire device during operation, reducing wear and malfunctions caused by uneven force distribution, extending the device's service life, and improving its stability and reliability.

[0048] Furthermore, the scraper 3 includes a first mounting plate 301 , one end of which is disposed on the rotating rod 2 ; a scraper 302 is slidably disposed on the first mounting plate 301 , and the scraper 302 abuts against the bottom surface of the first cavity 101 .

[0049] In this embodiment, one end of the first mounting plate 301 is securely welded to the rotating rod 2, ensuring it does not loosen or fall off during rotation. The scraper 302 is mounted on the first mounting plate 301. The scraper 302 exhibits excellent wear and corrosion resistance. During operation, the scraper 302 can be flexibly slid and adjusted on the first mounting plate 301 to accommodate varying material properties and operating conditions.

[0050] The advantage lies in the sliding arrangement of the first mounting plate 301 and the scraper 302. The scraper 302 is slidably mounted on the first mounting plate 301, allowing its position to be flexibly adjusted according to actual conditions, greatly improving the adaptability of the equipment. This design also facilitates the replacement and maintenance of the scraper 302. When the scraper 302 becomes worn or damaged, it can simply be slid off the first mounting plate 301 for replacement, reducing equipment maintenance costs and downtime, while improving production efficiency.

[0051] Furthermore, the first mounting plate 301 has a plurality of first protrusions 3011, the scraper 302 has a first groove 3021 and a first abutting portion 3022, and the scraper 3 further includes a sliding block 303. The sliding block 303 is used in pairs, and the sliding block 303 has a first abutting surface 3031, a second abutting surface 3032 and a second abutting portion 3033. The sliding blocks 303 used in pairs are slidably arranged on the first protrusion 3011. After the first groove 3021 abuts against the two first abutting surfaces 3031, the sliding blocks 3 used in pairs are 03 approach each other, and after the two first abutting portions 3022 slide and abut against the second abutting surface 3032, the sliding blocks 303 used in pairs approach each other. After the two sliding blocks 303 are completely abutted, the first protrusion 3011 enters or disengages from the first groove 3021; ​​both ends of the elastic member 304 abut against the two sliding blocks 303 respectively, for providing a force to move the two sliding blocks 303 away from each other, and the fastener 305 passes through the first mounting plate 301 and the scraper 302, for limiting the relative position of the first mounting plate 301 and the scraper 302.

[0052] In this embodiment, when preparing to install the scraper 302 on the first mounting plate 301, the first groove 3021 of the scraper 302 is first aligned with the first protrusion 3011 on the first mounting plate 301, and one side of the first groove 3021 abuts against the first abutting surfaces 3031 of the two sliding blocks 303. During the abutment process, due to the interaction of forces, the two sliding blocks 303 begin to move closer to each other. As the scraper 302 is pushed further, when the two sliding blocks 303 are fully abutted together, the first protrusion 3011 and the two sliding blocks 303 begin to enter the first groove 3021. Once the first protrusion 3011 is fully in the first groove 3021, the elastic member 304 begins to take effect, and its elastic restoring force forces the two sliding blocks 303 away from each other. At this point, the second abutting portion 3033 on the sliding block 303 tightly abuts the scraper 302, effectively preventing the scraper 302 from separating from the first mounting plate 301. Finally, install the fastener 305. The fastener 305 passes through the first mounting plate 301 and the scraper 302, firmly locking them in place and ensuring that the scraper 302 does not loosen or shift during operation. When the scraper 302 needs to be removed from the first mounting plate 301, the fastener 305 must first be removed to release the lock between the first mounting plate 301 and the scraper 302. Then, slide the scraper 302 upward. During the sliding process, the first abutting portion 3022 on the scraper 302 will abut against the second abutting surface 3032 of the sliding block 303. Under the action of force, the two sliding blocks 303 move closer to each other again. When the two sliding blocks 303 are completely abutted together, the lock between the scraper 302 and the first mounting plate 301 is released, and the scraper 302 can now be easily removed from the first mounting plate 301. After the scraper 302 is removed, the two sliding blocks 303 will move away from each other under the action of the elastic member 304 and return to the initial state, ready for the next installation.

[0053] The advantage is that the coordination of the first groove 3021, the first protrusion 3011, and the sliding block 303 makes installation of the scraper 302 simple and quick. Operators can complete installation by simply following the correct steps without using complex tools or performing tedious operations, greatly improving work efficiency. When the scraper 302 needs to be replaced or repaired, disassembly is equally simple. The abutment structure between the scraper 302 and the sliding block 303, as well as the design of the fastener 305, allows the scraper 302 to be removed by simply removing the fastener 305 and then sliding it. This is convenient and quick, reducing maintenance costs and time. After the scraper 302 is installed, the locking action of the fastener 305 and the coordination between the elastic member 304 and the sliding block 303 ensure a secure and reliable connection between the scraper 302 and the first mounting plate 301. The presence of the elastic member 304 ensures that the sliding block 303 maintains a certain pressure, preventing the scraper 302 from loosening or falling off, thereby ensuring the stability and safety of the equipment during operation. For example, when the device is running at high speed, the scraper 302 will not be displaced or fall off due to vibration or external force, thereby ensuring the normal operation of the device.

[0054] Furthermore, it also includes a second mounting plate 4, which is arranged at the feed port 102 and is connected to the feed port 102; the first rotating plate 5 is rotatably arranged on the second mounting plate 4 and coincides with the axis of the second mounting plate 4; there are several rotating blocks 6, and several rotating blocks 6 are rotatably arranged on the second mounting plate 4. After the first rotating plate 5 rotates, the rotating block 6 rotates. After the rotating block 6 rotates, the gap formed between the several rotating blocks 6 increases or decreases.

[0055] In this embodiment, the second mounting plate 4 is fixed to the feed port 102. The first rotating plate 5 is mounted on the second mounting plate 4 to ensure stable rotation. Rotating blocks 6 are evenly distributed on and connected to the second mounting plate 4. Rotating blocks 6 rotate when the first rotating plate 5 rotates. As the rotating blocks 6 rotate, the gaps between the rotating blocks 6 increase or decrease accordingly, thereby enabling precise control of the feed rate.

[0056] The advantage is that the rotation of the rotating blocks 6 can be precisely controlled by adjusting the first rotating plate 5, thereby adjusting the gap size between the rotating blocks 6 to achieve precise control of the feed rate. This design allows the equipment to adapt to different production needs and material characteristics, improving the versatility and production efficiency of the equipment.

[0057] Furthermore, the first rotating plate 5 has first gear teeth 501 , the rotating block 6 has second gear teeth 601 , and the first gear teeth 501 mesh with a plurality of second gear teeth 601 .

[0058] In this embodiment, a circle of fine first gear teeth 501 is evenly distributed along the edge of the first rotating plate 5. The edge of the rotating block 6 is correspondingly machined with second gear teeth 601 that match the first gear teeth 501. When the first rotating plate 5 rotates, the first gear teeth 501 and the second gear teeth 601 engage with each other, driving the rotating block 6 through a gear transmission. This gear-engaging transmission method offers the advantages of precise transmission ratios and high transmission efficiency, ensuring stable and reliable transmission between the first rotating plate 5 and the rotating block 6.

[0059] The advantage is that the meshing transmission of the first gear 501 and the second gear 601 makes the transmission between the first rotating plate 5 and the rotating block 6 more accurate and stable, avoiding unstable feed amount or equipment failure caused by transmission error, and improving the working accuracy and reliability of the equipment.

[0060] Furthermore, the rotating blocks 6 are evenly distributed along the circumference of the axis of the second mounting plate 4 .

[0061] In this embodiment, the rotating blocks 6 are evenly spaced around the circumference of the second mounting plate 4 along the axis. Each rotating block 6 is identical in shape and size. During operation, when the first rotating plate 5 rotates, the gear transmission mechanism drives each rotating block 6 to rotate synchronously and uniformly. For example, when the first rotating plate 5 rotates clockwise by a certain angle, the rotating blocks 6 simultaneously rotate outward or inward by the same angle, thereby ensuring uniform and consistent changes in the gaps between the rotating blocks 6.

[0062] The advantage is that the uniform distribution of the rotating blocks 6 around the circumference allows for more uniform changes in the gaps between the rotating blocks 6 when adjusting the feed rate, thus avoiding overfeeding or underfeeding in some areas. This design improves the accuracy and stability of the equipment's feed rate control, helping to ensure the continuity of the production process and the stability of product quality.

[0063] Furthermore, it also includes:

[0064] The cleaning member 7 passes through the housing 1 , with one end located in the first cavity 101 .

[0065] In this embodiment, the cleaning component 7 is a cleaning agent pipeline with a nozzle, and the diameter of the cleaning agent pipeline is reasonably selected according to the cleaning requirements of the equipment and the cleaning agent pressure. The cleaning agent pipeline passes through the shell 1 through a sealed channel reserved on the shell 1. A sealing rubber ring is used to seal the channel and the cleaning agent pipeline to prevent the cleaning agent from leaking to the outside of the equipment during the cleaning process. One end of the cleaning agent pipeline is located in the first cavity 101, and a plurality of high-pressure nozzles are installed at this end, which can cover every corner of the first cavity 101. When the equipment needs to be cleaned, the cleaning agent pipeline valve is opened, and the cleaning agent is sprayed out through the nozzle under a certain pressure to form a high-pressure spray to fully flush the inside of the first cavity 101.

[0066] The advantage is that the provision of the cleaning part 7 facilitates the cleaning of the equipment after use, can effectively remove the residual materials and dirt inside the equipment, keep the equipment clean and sanitary, prevent the residual materials from contaminating the next production, and ensure the stability of product quality.

[0067] Furthermore, the discharge port 103 is tapered, and the cross-sectional diameter of the discharge port 103 gradually decreases from one end close to the first cavity 101 to the other end.

[0068] In this embodiment, discharge port 103 is made of stainless steel and features a tapered design, with a larger diameter at the end closest to first cavity 101 and gradually tapering toward the other end. The taper of discharge port 103 has been precisely calculated to ensure smooth material flow under the influence of gravity and internal pressure. During material conveying, the tapered shape of discharge port 103 guides material flow smoothly, reducing clogging and accumulation at discharge port 103.

[0069] The advantage is that the design of the tapered discharge port 103 allows materials to flow out of the equipment more smoothly under the action of gravity, reducing the risk of material residue and blockage at the discharge port 103. This design also helps to improve material discharge speed and production efficiency. For example, in some continuous production processes, fast and smooth discharge can ensure the continuity of the production process, reduce equipment downtime, and improve overall production efficiency. Furthermore, the tapered discharge port 103 can also reduce material splashing and dust during the discharge process, improving the working environment.

[0070] Furthermore, it also includes:

[0071] The feeding device 8 has one end disposed at the end of the discharge port 103 away from the first cavity 101 .

[0072] In this embodiment, the feeding device 8 is a screw conveyor made of carbon steel, one end of which is mounted via a flange connection at the end of the discharge port 103 away from the first cavity 101. After the material flows out of the discharge port 103, the screw conveyor transports it to the next production link or storage location.

[0073] The feeding device 8 improves the degree of production automation and material conveying efficiency, facilitates the connection and coordination with other equipment, and optimizes the production process.

[0074] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
