Description

Technical Field

[0001] This utility model relates to the field of calcium carbide production technology, specifically to a foreign matter screening and feeding device for calcium carbide furnaces. Background Technology

[0002] In the calcium carbide production process, lime and carbon materials are used as the main raw materials for calcination to meet the needs of calcium carbide production and are then stored in lime silos for later use. The general transportation process is as follows: the raw materials are first transported to the top of the feeding port by a transmission device driven by a transmission belt, and then fall into the feeding port. They are then fed into the annular feeder for batch transportation. However, during the feeding process, the problem of large foreign particles often occurs. These large foreign particles may come from nodules formed during the calcination of the raw materials, or from large particles contained in the raw materials themselves, or even from detached parts such as wear-resistant plates of the equipment. The presence of these foreign particles poses a great threat to the normal operation of the calcium carbide furnace. For example, when large foreign particles enter the feeding pipe, their large size can easily cause blockages in the pipe, thereby affecting the feeding and reaction process of the calcium carbide furnace. This will not only reduce production efficiency and increase maintenance costs, but may even lead to machine failure and shutdown in severe cases. Utility Model Content

[0003] The purpose of this utility model is to provide a foreign object screening and feeding device for calcium carbide furnaces, so as to solve the problems of machine failure and product quality caused by foreign objects being discharged into the calcium carbide furnace.

[0004] To achieve the above objectives, the basic solution provided by this utility model is as follows: a foreign object screening and feeding device for a calcium carbide furnace, comprising a cylinder, a funnel on the cylinder, a box on the funnel, a number of steel bars inside the cylinder, the steel bars intersecting to form a mesh structure, a connecting plate covering the edge of the mesh structure, an arc-shaped groove on the inner wall of the cylinder, the connecting plate engaging with the arc-shaped groove, and a limiting component hinged to the outer wall of the cylinder, the limiting component being located on both sides of the arc-shaped through hole.

[0005] The working principle of this utility model is as follows: the raw material is fed into the funnel by the belt and enters the cylinder through the funnel. Several steel bars are distributed in a mesh. The steel bars are surrounded by connecting plates. The connecting plates are inserted into the grooves to fix the steel bars in the right position so that they will not fall. Raw materials of suitable size continue to fall downward through the gaps, while larger particles and foreign objects are blocked by the steel bars and cannot fall downward into the cylinder.

[0006] The advantages of this invention are: it can effectively separate and collect large particles of foreign matter in materials, ensuring the stable and reliable quality of materials entering the calcium carbide furnace, preventing the machine from being blocked and damaged by large particles of foreign matter, reducing production interruptions and maintenance costs caused by foreign matter, and improving production efficiency and quality.

[0007] Option 2, an optimal choice from the basic option, features an anti-clogging detector installed on the outside of the enclosure. This detector uses infrared sensing and is connected to the power transmission device. When large foreign objects accumulate to a set height, the detector sends a signal to the power transmission device, causing it to stop operating. This option offers advantages such as real-time monitoring and early warning, and reduced maintenance costs.

[0008] Option 3, a preferred option of the basic design, features an arc-shaped through-hole on one side of the cylinder. The mesh structure is movably connected to the cylinder through this through-hole. The inner diameter and arc length of the arc-shaped through-hole match the outer diameter of the mesh structure, and its height matches the width of the mesh structure. The connecting plate is inserted into the arc-shaped through-hole from the outside and enters the cylinder through the through-hole for placement and installation. When replacement is needed after prolonged use, it can also be easily removed and replaced through the arc-shaped through-hole.

[0009] Option four, a preferred option of option three, features a handle on the connecting plate. Installing a handle on the side of the connecting plate exposed outside the cylinder saves time and effort.

[0010] Option 5, an optimal choice from the basic option, features a manhole on the cylinder. When large foreign objects become clogged to a certain extent, the manhole is opened, allowing the foreign objects to be directly discharged and cleaned, reducing cleaning time and improving work efficiency.

[0011] Option 6, an optimal choice from the basic option, features a dustproof cloth on the cylinder. Dust leakage and overflow can occur at the connection between the bottom of the cylinder and the feeder below; the dustproof cloth reduces dust generation.

[0012] Option 7, a preferred embodiment of Option 3, includes a limiting assembly comprising a sleeve and a pin. A rotating rod is rotatably connected inside the sleeve. The sleeve and the cylinder are fixedly connected. A connecting rod is fixedly connected to the rotating rod, and a baffle is fixedly connected to the free end of the connecting rod. The pin passes through the sleeve and the rotating rod in sequence. By using the sleeve to limit the position of the isolation device, it ensures that during the material feeding process, there will be no deviation in forward / backward or left / right position due to mechanical vibration.

[0021] Example

[0022] The basic implementation examples are as follows: Figures 1 to 6 As shown: A foreign object screening and feeding device for a calcium carbide furnace includes a cylinder 1, a funnel 2 on the cylinder 1, a box 5 on the funnel 2, a plurality of steel bars 3 inside the cylinder 1, the plurality of steel bars 3 intersecting to form a mesh structure, the edge of the mesh structure being covered by a connecting plate 4, an arc-shaped groove 10 on the inner wall of the cylinder 1, the connecting plate 4 engaging with the arc-shaped groove 10, and a limiting component 8 hinged to the outer wall of the cylinder 1, the limiting component 8 being located on both sides of an arc-shaped through hole 11, the limiting component 8 including a sleeve 801 and a pin 802, a rotating rod 803 rotatably connected inside the sleeve 801, the sleeve 801 and The cylinder 1 is fixedly connected, and a connecting rod 804 is fixedly connected to the rotating rod 803. A baffle 805 is fixedly connected to the free end of the connecting rod 804. The pin 802 passes through the sleeve 801 and the rotating rod 803 in sequence. An arc-shaped through hole 11 is opened on one side of the cylinder 1. The mesh structure is movably connected to the cylinder 1 through the arc-shaped through hole 11. A sealing ring 10 is provided on the arc-shaped through hole 11. A handle 7 is provided on the connecting plate 4. An anti-clogging detector 6 is provided on the outside of the box 5. The type of anti-clogging detector 6 is ebch-50 chute anti-clogging detector. A manhole 12 is provided on the cylinder 1. A dustproof cloth 9 is provided on the cylinder 1.

[0023] The specific implementation process of this embodiment is as follows: The upper part of the feeding port is connected to the transmission belt. Limestone, carbon, and other raw materials are transported to the upper part of the box 5 by the transmission belt, and then fall downwards, passing through the box 5, funnel 2, and cylinder 1 in sequence. When the raw materials reach the mesh layer composed of several steel bars 3, those smaller than the mesh continue to fall, while larger particles are blocked by the steel bars 3 and cannot fall further. The feeding and screening process continues. During this period, the anti-blocking detector 6 continuously monitors the feeding situation. When the blocked large particles reach the set height, the anti-blocking detector 6 sends a signal to the transmission device on the transmission belt. After receiving the signal, the transmission device stops feeding. Then, the workers discharge and clean the large particles accumulated inside through the manhole 12, perform secondary crushing on larger raw materials, and remove other foreign objects. After cleaning, the transmission device is turned on to continue feeding. The lower part of the feeding port is connected to the annular feeder. The raw materials fall from the cylinder 1 into the annular feeder for batch feeding. During this process, the dustproof cloth 9 covers the gap between the cylinder 1 and the annular feeder to cover the dust. When the steel bar 3 has been used for too long, it will be worn and corroded. At this time, the transmission device needs to be shut down and the entire screening assembly needs to be replaced. First, pull out the pin 802, then rotate the connecting rod 804 outward to make the baffle 805 leave the connecting plate 4. Then pull the handle 7 to pull the connecting plate 4 and the steel bar 3 out of the cylinder 1 together. Then put the new connecting plate 4 and the steel bar 3 into the cylinder 1 through the arc-shaped through hole 11. Then push the handle 7 to push the connecting plate 4 into the arc-shaped groove 10 on the inner wall of the cylinder 1. Finally, rotate the connecting rod 804 inward to make the baffle 805 abut against the connecting plate 4. Then insert the pin 802 into the sleeve 801 and the rotating rod 803 to limit and fix the mesh structure and the limiting assembly 8, and continue the material feeding and screening work.
