Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cement production, and in particular to a feeding device for cement production. Background Technology
[0002] Cement is a powdery hydraulic inorganic binder that forms a paste when mixed with water. It can harden in air or water and can firmly bind materials such as sand and stone together. The main raw materials for cement include limestone, clay, iron ore, and coal. These raw materials need to be crushed first, and then the various raw materials are mixed in proportion to form a uniform raw meal. During the mixing process, the material is usually continuously fed through a hopper. Therefore, a feeding device is required for cement production.
[0003] In existing cement production feeding devices, after the raw materials have been crushed and ground, they are directly fed into the mixing tank. Some of the raw materials that have not been ground completely will affect the mixing effect. Currently, the raw materials are generally fed directly through the hopper, which does not allow for screening. Utility Model Content
[0004] The purpose of this utility model is to provide a feeding device for cement production, in order to solve the problem mentioned in the background art that in existing cement production feeding devices, after the raw materials are crushed and ground, some of the raw materials that are not thoroughly ground will affect the mixing effect after being directly fed into the mixing tank. Existing devices generally feed directly through a hopper, which makes it impossible to screen the raw materials.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for cement production, comprising a feeding bucket, a top cover fixedly installed at one end of the feeding bucket, an inlet opening on one side surface of the top cover, a drive motor fixedly installed on the upper surface of the top cover, a connecting shaft fixedly connected to the output end of the drive motor, a screening mechanism provided at one end of the connecting shaft, a fixing groove opened on one side surface of the feeding bucket, a scraper fixedly installed at one end of the fixing groove, and a receiving plate fixedly installed on one side surface of the feeding bucket.
[0006] Preferably, the screening mechanism includes a fixed ring, a limiting ring, a screen, a connecting block, a limiting groove, a spring, a spiral rod, a support frame, a groove, a protrusion, a fixed block, and a ball. A fixed ring is provided at one end of the connecting shaft. A limiting ring is fixedly installed on the inner ring of the fixed ring, and a screen is fixedly installed on the outer ring of the fixed ring. A connecting block is embedded at one end of the limiting ring. Limiting grooves are formed on both sides of the surface of the connecting block. A spring is fixedly installed at one end of each limiting groove. A spiral rod is fixedly connected to one end of the connecting block. A support frame is bearing-connected to one end of the spiral rod. A groove is formed on the upper surface of the screen, and a protrusion is provided on the surface of the groove. A fixed block is fixedly installed on the inner surface of the feeding hopper, and a ball is welded to one end of the fixed block.
[0007] Preferably, one end of the connecting block passes through the limiting ring and is fixedly connected to one end of the connecting shaft, and one side of the limiting ring is fixedly connected to the spring.
[0008] Preferably, the fixing blocks are evenly distributed in the inner ring of the feeding barrel, and one end of the sphere is in contact with the surface of the groove.
[0009] Preferably, the scraper is attached to the upper surface of the screen, and the position of the receiving plate corresponds to the position of the fixing groove.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This feeding device for cement production, through the setting of the screening mechanism, in use, drives the connecting block at one end of the connecting shaft to rotate via the drive motor. The connecting block and the limiting ring are fitted together, and at the same time, the screen on the outer ring of the limiting ring and the fixed ring rotates. While the screen is rotating, the raised positions on the groove surface will continuously contact the ball. Under the pressure of the ball, the screen will vibrate through the spring. During the vibration process, qualified raw materials are quickly screened out and then fed into the mixing equipment through the feeding bucket below the screen. Larger raw materials are blocked by the scraper while vibrating and rotating. Moreover, the scraper has an L-shaped structure, and larger raw materials will accumulate on one side of the scraper and then move to one side of the fixed trough and be conveyed out through the receiving plate. This ensures that the raw materials fed into the feeding bucket are qualified without affecting the screening of the screen. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-4 The present invention provides a technical solution: a feeding device for cement production, including a feeding bucket 1, a top cover 2 fixedly installed at one end of the feeding bucket 1, an inlet 3 opened on one side surface of the top cover 2, a drive motor 4 fixedly installed on the upper surface of the top cover 2, a connecting shaft 5 fixedly connected to the output end of the drive motor 4, a screening mechanism 6 provided at one end of the connecting shaft 5, a fixing groove 7 opened on one side surface of the feeding bucket 1, a scraper 8 fixedly installed at one end of the fixing groove 7, and a receiving plate 9 fixedly installed on one side surface of the feeding bucket 1.
[0018] Furthermore, the screening mechanism 6 includes a fixed ring 601, a limiting ring 602, a screen 603, a connecting block 604, a limiting groove 605, a spring 606, a spiral rod 607, a support frame 608, a groove 609, a protrusion 610, a fixed block 611, and a ball 612. A fixed ring 601 is provided at one end of the connecting shaft 5. The inner ring of the fixed ring 601 is fixedly fitted with the limiting ring 602, and the outer ring of the fixed ring 601 is fixedly fitted with the screen 603. One end of the limiting ring 602 is embedded in... A connecting block 604 has limit grooves 605 on both sides of its surface. A spring 606 is fixedly installed at one end of the limit groove 605. A spiral rod 607 is fixedly connected to one end of the connecting block 604. A support frame 608 is connected to one end of the spiral rod 607 by a bearing. A groove 609 is provided on the upper surface of the screen 603. A protrusion 610 is provided on the surface of the groove 609. A fixing block 611 is fixedly installed on the inner surface of the feeding hopper 1. A ball 6 is welded to one end of the fixing block 611. 12. Through the arrangement of the fixing ring 601, limiting ring 602, screen 603, connecting block 604, limiting groove 605, spring 606, spiral rod 607, support frame 608, groove 609, protrusion 610, fixing block 611 and ball 612, in use, the drive motor 4 drives the connecting block 604 at one end of the connecting shaft 5 to rotate. Since the connecting block 604 is connected to the limiting ring 602 through the limiting groove 605, it drives the fixing ring 602 on the outer ring of the limiting ring 602. 01 and screen 603 rotate synchronously. While screen 603 is rotating, the protrusions 610 in the grooves 609 on its surface will be squeezed when they encounter the ball 612. Under the continuous squeezing and the rebound of spring 606, screen 603 will continue to vibrate, screening the qualified raw materials to the bottom and then discharging them through the lower opening of the feeding hopper 1. At the same time, the screw rod 607 and the support frame 608 will continue to rotate under the drive of the drive motor 4, which can effectively prevent outlet blockage.
[0019] Furthermore, one end of the connecting block 604 passes through the limiting ring 602 and is fixedly connected to one end of the connecting shaft 5. One side of the limiting ring 602 is fixedly connected to the spring 606. Through the setting of the spring 606, the screen 603 can extend and retract through the limiting ring 602 at one end of the connecting block 604, and can generate vibration under the elastic action of the spring 606.
[0020] Furthermore, the fixing blocks 611 are evenly distributed in the inner ring of the feeding barrel 1, and one end of the ball 612 is in contact with the surface of the groove 609. Through the setting of the ball 612, the ball 612 can work with the protrusion 610 to continuously squeeze the screen 603.
[0021] Furthermore, the scraper 8 is attached to the upper surface of the screen 603, and the position of the receiving plate 9 corresponds to the position of the fixing groove 7. Through the setting of the scraper 8, the scraper 8 can block larger particles of raw materials, and the raw materials will be discharged through the fixing groove 7 along one side of the scraper 8, and then conveyed and discharged by the receiving plate 9.
[0022] Working principle: First, the raw materials to be mixed are poured in from one end of the feed port 3. Then, the drive motor 4 drives the connecting block 604 at one end of the connecting shaft 5 to rotate. Since the connecting block 604 is connected to the limiting ring 602 through the limiting groove 605, it drives the fixing ring 601 on the outer ring of the limiting ring 602 and the screen 603 to rotate synchronously. While the screen 603 is rotating, the protrusion 610 in the groove 609 on the surface will be squeezed when it encounters the ball 612. Under the continuous squeezing and the rebound action of the spring 606, the screen 603 will continue to vibrate, screening the qualified raw materials to the bottom and then discharging them through the lower opening of the feeding barrel 1. At the same time, the larger particles of raw materials will move along one side of the scraper 8 and then be discharged through the fixing groove 7 to the surface of the receiving plate 9.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
