Abstract
Description
Technical Field
[0001] This utility model relates to a discharge valve, specifically a safety-type quartz sand bin discharge valve, belonging to the field of discharge valve technology. Background Technology
[0002] Quartz sand is an industrial mineral material processed from quartz stone, characterized by high hardness, high temperature resistance, and strong chemical stability. A quartz sand silo is a specialized facility used for storing and homogenizing quartz sand raw materials. The quartz sand silo discharge valve is a key piece of equipment used to control the unloading of quartz sand from the silo.
[0003] However, when material is discharged from the sand bin into the hopper through the discharge valve, the pressure at the cone of the bin increases the consolidation strength of the sand particles, which easily forms bridging, preventing the material from being discharged from the bottom of the sand bin. This affects the normal discharge of the material and is detrimental to improving the performance of the discharge valve. Utility Model Content
[0004] The purpose of this utility model is to provide a safe quartz sand silo discharge valve to solve the above problems. The gear drives the gear ring to rotate, so that when the rotating ring rotates in the sleeve, it can drive the scraper to rotate in the feeding hopper and the sleeve, thereby causing the stirring rod to rotate and destroy the electrostatic force between the material particles, preventing bridging and preventing the quartz sand from being discharged normally.
[0005] This utility model achieves the above-mentioned objective through the following technical solution: a safe quartz sand silo discharge valve, comprising a storage silo, a feeding hopper fixedly installed at the bottom end of the storage silo, a sleeve fixedly installed at the bottom end of the feeding hopper, a rotating mechanism rotatably installed inside the sleeve, the rotating mechanism comprising a motor and a rotating shaft, the motor fixedly installed on the sleeve, the output end of the motor fixedly connected to the rotating shaft via a coupling, a gear fixedly installed on the rotating shaft, a gear ring meshing on the gear, a rotating ring fixedly installed on the gear ring, two scraper plates symmetrically fixedly connected to the top end of the rotating ring, a plurality of stirring rods fixedly installed at equal intervals on the scraper plates, a support block fixedly connected to the sleeve, a discharge mechanism rotatably installed on the support block, and a discharge hopper connected to the bottom end of the sleeve.
[0006] Preferably, the rotating shaft and the sleeve are rotatably connected, and the cross-sectional diameter of the gear is smaller than the cross-sectional diameter of the gear ring.
[0007] Preferably, the rotating ring and the sleeve are rotatably connected, and the portion of the rotating ring near the inner diameter is provided with an inclined structure.
[0008] Preferably, the scraper is rotatably connected to the hopper and the sleeve, and the part of the scraper that contacts the hopper is arranged with an inclined structure.
[0009] Preferably, a plurality of the stirring rods are equidistantly arranged on the side of the scraper away from the feed hopper, and the stirring rods are inclined.
[0010] Preferably, the feeding hopper is internally connected to the unloading hopper via a sleeve, and both the feeding hopper and the unloading hopper are arranged with a conical structure.
[0011] Preferably, the material feeding mechanism includes a bracket and a hydraulic rod. The bracket is fixedly connected to the sleeve, and the hydraulic rod is fixedly installed on the bracket. A connecting block is fixed to the telescopic end of the hydraulic rod. A rotating plate is rotatably installed on the connecting block. A rotating rod is fixedly connected to the rotating plate. A baffle plate is fixedly installed at the bottom end of the rotating rod. The baffle plate is rotatably connected to the sleeve.
[0012] Preferably, the rotating rod is rotatably connected to the support block, and the baffle plate is arranged with an arc surface structure.
[0013] Preferably, the bracket is located near the support block on the sleeve, and the baffle plate rotates inside the hopper.
[0014] The beneficial effects of this utility model are as follows: After the material feeding mechanism is started, the bottom end of the sleeve is in an open state, so that the material in the upper hopper can be discharged into the lower hopper through the sleeve. During the feeding process, the motor switch installed on the sleeve is started. The output end of the motor is fixedly connected to the rotating shaft through the coupling. The rotating shaft drives the gear fixed on the side wall to rotate inside the sleeve. Since there is a gear ring meshing on the gear, the gear drives the gear ring to rotate, which can make the rotating ring fixed together with the gear ring rotate. Two scraper plates are symmetrically fixed at the top of the rotating ring. When the scraper plates rotate along the inner wall of the upper hopper and the sleeve, they can scrape off the material attached to the inner wall, so that the material is discharged more thoroughly. Several stirring rods fixed at equal intervals on the side wall of the scraper plates agitate the material in the upper hopper during the rotation. The rotation of the stirring rods can destroy the electrostatic force between the material particles, prevent bridging, and prevent the quartz sand from falling normally, so that the lower hopper can safely discharge the material.

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.
[0025] Please see Figures 1-8As shown, a safety-type quartz sand silo discharge valve includes a storage silo 1. A feeding hopper 2 is fixedly installed at the bottom of the storage silo 1. A sleeve 3 is fixedly installed at the bottom of the feeding hopper 2. A rotating mechanism 7 is rotatably installed inside the sleeve 3. The rotating mechanism 7 includes a motor 701 and a rotating shaft 707. The motor 701 is fixedly installed on the sleeve 3. The output end of the motor 701 is fixedly connected to the rotating shaft 707 via a coupling. The rotating shaft 707 is rotatably connected to the sleeve 3. A gear 706 is fixedly installed on the rotating shaft 707. A gear ring 705 meshes with the gear 706. The cross-sectional diameter of the gear 706 is smaller than the cross-sectional diameter of the gear ring 705. A rotating ring 704 is fixedly installed on the gear ring 705. The rotating ring 704 is rotatably connected to the sleeve 3. The portion of the rotating ring 704 near its inner diameter is arranged with an inclined structure. The rotating shaft 707 drives the gear 706, which is fixed to the side wall, to rotate inside the sleeve 3. Gear 706 drives gear ring 705 to rotate, thereby causing rotating ring 704 to rotate inside sleeve 3. Two scraper plates 702 are symmetrically fixedly connected to the top of rotating ring 704. The scraper plates 702 are rotatably connected to hopper 2 and sleeve 3. The part of scraper plate 702 that contacts hopper 2 is set with an inclined structure. Several stirring rods 703 are fixedly installed at equal intervals on scraper plate 702. The stirring rods 703 are equidistantly arranged on the side of scraper plate 702 away from hopper 2 and are inclined. During rotation, stirring rods 703 agitate the material in hopper 2. The rotation of stirring rods 703 can destroy the electrostatic force between material particles and prevent arch bridging that would prevent quartz sand from falling normally. Support block 5 is fixedly connected to sleeve 3. Discharge mechanism 6 is rotatably installed on support block 5. Discharge hopper 4 is connected to the bottom of sleeve 3.
[0026] As a technical optimization of this utility model, the feeding hopper 2 is internally connected to the unloading hopper 4 through the sleeve 3. When the bottom end of the sleeve 3 is in an open state, the feeding hopper 2 and the unloading hopper 4 can be internally connected, thereby allowing the material to be transported to the unloading hopper 4; both the feeding hopper 2 and the unloading hopper 4 are arranged with a conical structure.
[0027] As a technical optimization of this utility model, the material feeding mechanism 6 includes a bracket 601 and a hydraulic rod 602. The bracket 601 is fixedly connected to the sleeve 3, and the bracket 601 is located near the support block 5 of the sleeve 3. The hydraulic rod 602 is fixedly installed on the bracket 601. A connecting block 603 is fixedly installed at the telescopic end of the hydraulic rod 602. A rotating plate 604 is rotatably installed on the connecting block 603. A rotating rod 605 is fixedly connected to the rotating plate 604. The rotating rod 605 is rotatably connected to the support block 5. The bottom end of the rotating rod 605... A baffle plate 606 is fixedly installed. The extension end of the hydraulic rod 602 drives the fixed end of the connecting block 603 to move. The connecting block 603 pushes the rotating plate 604 to rotate, which can cause the rotating plate 604 to drive the rotating rod 605 to rotate along the inner wall of the sleeve 3 and the support block 5, and cause the baffle plate 606 to rotate along the bottom end of the sleeve 3. The baffle plate 606 is rotatably connected to the sleeve 3. The baffle plate 606 is set with an arc surface structure. The baffle plate 606 rotates inside the feed hopper 4, so that the sleeve 3 and the inside of the feed hopper 4 are connected, and the material is discharged into the feed hopper 4 through the sleeve 3.
[0028] In use, this invention firstly stores quartz sand through the storage silo 1; the storage silo 1 is internally connected to the feeding hopper 2, allowing material to be discharged into the feeding hopper 2; during material discharge, the control switch of the hydraulic rod 602 is turned on, causing its telescopic end to drive the end-fixed connecting block 603 to move. A rotating plate 604 is rotatably mounted on the connecting block 603. The connecting block 603 pushes the rotating plate 604 to rotate, causing the rotating plate 604 to drive the rotating rod 605 fixed on the inner wall to rotate. The rotating rod 605 rotates along the inner wall of the sleeve 3 and the support block 5, causing it to drive the end-fixed baffle plate 606 to rotate. The baffle plate 606 rotates along the bottom end of the sleeve 3, allowing the sleeve 3 to connect with the inside of the discharge hopper 4, thus allowing material to be discharged into the discharge hopper 4 through the sleeve 3; during the material discharge process, the motor 70 installed on the sleeve 3 is started. 1. A switch and a motor 701 are connected to a rotating shaft 707 via a coupling. The rotating shaft 707 drives a gear 706 fixed to the side wall to rotate inside the sleeve 3. Since a gear ring 705 meshes on the gear 706, the gear 706 drives the gear ring 705 to rotate, which can rotate the rotating ring 704 fixed to the gear ring 705. Two scraper plates 702 are symmetrically fixed at the top of the rotating ring 704. When the scraper plates 702 rotate along the inner wall of the feeding hopper 2 and the sleeve 3, they can scrape off the material attached to the inner wall, thus making the material discharge more thorough. Several stirring rods 703 fixed at equal intervals on the side wall of the scraper plates 702 agitate the material in the feeding hopper 2 during rotation. The rotation of the stirring rods 703 can break the electrostatic force between the material particles, prevent bridging, and prevent the quartz sand from falling normally, thus allowing the material to fall safely from the discharge hopper 4.
