Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to a transportation device for stable feeding of viscous materials. Background Art

[0002] Desulfurized gypsum is an industrial by-product in the steel industry. It is made by adding water to lime-limestone powder to make a slurry, and then treating sulfur dioxide in the flue as an absorbent. The product is concentrated and dehydrated. It has the characteristics of high water content and high viscosity. One of the major uses of desulfurized gypsum is as a retarder in cement. At present, dry conveying is the most common method for conveying powdered materials in various building materials industries, among which spiral reamer conveying is the most common method for conveying materials. In the cement production process, viscous materials such as desulfurized gypsum are generally discharged by reamer conveying. However, in the process of spiral reamer conveying, the following problems exist:

[0003] 1. Due to the high water content and viscosity of desulfurized gypsum itself, it is difficult to feed the material and the feeding is unstable during the production process.

[0004] 2. Due to the presence of foreign matter in the desulfurized gypsum, it is easy to get stuck or blocked when using a spiral reamer for transportation, causing the reamer motor coupling to break and the equipment to stop, resulting in large fluctuations in the discharge of the desulfurized gypsum, poor discharge and breakage, which in turn affects the quality of cement products.

[0005] 3. When personnel are dealing with reamer abnormalities, maintenance time is long and there are risks of mechanical injury, object impact, etc.

[0006] Therefore, the key to solving this problem is to study an effective and applicable device for the stable transportation of desulfurized gypsum to deal with sticking, blockage and equipment abnormalities during use, to achieve stable material unloading and transportation, and to protect the stable transportation of the production system. Utility Model Content

[0007] In view of the problems in the prior art of difficult feeding and unstable feeding of viscous materials such as desulfurized gypsum during the production batching process, the utility model provides a conveying device for stable feeding of viscous materials to solve the above problems.

[0008] The technical solution of the utility model is as follows:

[0009] A conveying device for stable feeding of viscous materials comprises a silo; the longitudinal section of the silo is an inverted trapezoid, and a drainage plate is provided on the inner wall; a discharge port is provided at the lower part of the silo, a conveyor belt is provided below the discharge port, one end of the conveyor belt is located below the discharge port, and the other end is located above a metering belt scale; ribs are provided on both side edges of the conveyor belt; and a metering roller is provided below the belt of the metering belt scale.

[0010] Furthermore, a vibration motor is provided on the outer side of the silo side wall for vibrating the silo during the unloading process to prevent the accumulation and blockage of sticky materials and ensure smooth unloading.

[0011] Furthermore, a baffle is provided above one end of the conveyor belt near the unloading port. When the unloading speed is fast and the unloading amount is large, the material can be timely blocked from spilling toward the tail, which is convenient for operation and cleaning of the material stored at the edge of the belt.

[0012] Furthermore, a scraper is provided at one end of the conveyor belt near the metering belt scale. When conveying sticky materials, a part of them will stick to the conveyor belt, and after long-term use, they will be hardened on the conveyor belt, making it difficult to clean. The scraper can clean the materials on the conveyor belt in time, and can also serve as a guide to neatly transfer the materials to the metering belt scale.

[0013] Furthermore, guide plates are provided on both sides of the metering roller. When materials are spilled on the metering roller below, the belt is easily deviated because the scattered materials are caught between the metering roller and the upper belt. Adding guide plates on both sides of the metering roller can prevent the belt scale from deviating and affecting the metering accuracy of the belt scale.

[0014] Furthermore, the conveyor belt is made of flexible plastic.

[0015] The beneficial effects of the utility model are:

[0016] The utility model provides a conveying device for stable feeding of viscous materials, and trapezoidal drainage plates are added on both sides of the inner wall of the desulfurized gypsum silo to change the discharge angle of the raw material silo to keep consistent with the size of the discharge port, thereby realizing the effect of accelerated drainage. A conveyor belt is used as a conveying method below the discharge port, and is staggered and has an upper and lower structure with the metering belt scale below. When the silo is stuck or blocked and foreign matter exists, it can be taken out from the upper conveyor belt, and the process processing time is short and easy to operate. The utility model can avoid the problems of frequent poor discharge, jamming, and blockage of viscous materials such as desulfurized gypsum during the production process, and the abnormalities of equipment such as motors, etc., avoid equipment damage, affect the quality of cement products, and realize a flexible way to handle abnormal problems on site. It has the advantages of flexible conveying methods, simple structure, easy use, and significant effects. BRIEF DESCRIPTION OF THE DRAWINGS
