Description

Metering cement clinker warehousing device

Technical Field

The invention relates to a metering warehousing device, in particular to a metering cement clinker warehousing device.

Background

The cement raw material is prepared from calcareous material, clayey material and a small amount of correction material (mineralizer, crystal seed, etc. are added sometimes, and coal is also added during production in vertical kiln) by mixing in proportion, and grinding to obtain a material with a certain fineness. Cement is one of common materials in the building industry, and the cement must be uniformly stirred with water and sand before use. Cement is a cementitious material used in civil engineering and is one of the most important building materials in the world. The production process of cement uses limestone, clay and silicon dioxide as main raw materials, and adopts the processes of crushing, proportioning and grinding to obtain raw material, then the raw material is fed into cement kiln and calcined into clinker, and cooled so as to obtain the invented semi-finished product. Clinker is an intermediate product (equivalent to a semi-finished product of cement) in the production process of cement, and some enterprises have a need to purchase clinker as a production raw material. When a cement manufacturer transports clinker to a company purchasing the clinker, the clinker is usually transported by a truck. Firstly, a truck is driven into the position below a clinker warehouse, then the clinker in the clinker warehouse is discharged into a hopper of the truck, and the truck filled with the clinker is driven into a wagon balance to be weighed, so that the factory transportation is shown to a purchasing enterprise on the premise of no overweight. During the process of discharging the clinker in the clinker warehouse into the hopper of the truck, the truck loader can only estimate the weight of the clinker loaded into the truck. When a truck loaded with clinker is driven into a weighbridge and weighed, an overweight or underloaded condition may occur. When the clinker aggregate is overweight, the overweight clinker aggregate needs to be unloaded; when the load is insufficient, clinker needs to be supplemented so as to fully utilize the load limit of the truck. It can be seen that this brings new workload and wastes manpower, material resources and time.

The clinker weighing device comprises a clinker warehouse for storing clinker and a weighing device for weighing the clinker, wherein a discharge port of the clinker warehouse is communicated to a feed port of the weighing device through a guide pipeline, the weight of the clinker continuously discharged from the discharge port of the clinker warehouse into the weighing device can be measured through the weighing device, and a discharge port of the weighing device is connected with a discharge pipeline and used for discharging the clinker measured by the weighing device into a hopper of a truck. When the clinker in the clinker warehouse is required to be discharged into the hopper of the truck, the truck runs into the position below the discharge pipeline, and the clinker continuously discharged from the discharge port of the clinker warehouse can be discharged into the hopper of the truck after being weighted and measured by the weighing device; when the weight measured by the weighing device approaches or reaches the load limit of the truck, the clinker is stopped to be discharged. At the moment, the clinker loaded by the truck is weighed by the weighing device, so that the requirement can be met at one time when the truck loaded with the clinker is driven into a wagon balance for weighing, and the condition of overweight or insufficient load is avoided. The weighing device is a disc weighing device. The clinker dust collector is used for pumping away clinker dust generated when clinker is discharged into a hopper of the truck. The clinker is often granular and powdery; when the clinker is discharged into the hopper of the truck from the discharge end of the clinker discharge pipeline, clinker dust is generated to pollute the surrounding environment, and the dust remover can pump away the clinker dust generated when the clinker is discharged into the hopper of the truck, so that the pollution to the surrounding environment is reduced. The dust remover is a bag type dust remover. The dust suction opening of the dust remover extends to the position near the discharge end of the discharge pipeline through a dust suction pipeline. The clinker dust generated when the discharge end of the clinker discharge pipeline is discharged into the hopper of the truck is basically concentrated at the position near the lower part of the discharge end, so that the clinker dust can be effectively pumped away when the design is adopted, and the pollution to the surrounding environment is reduced. The discharge end of the discharge pipeline is provided with a horn mouth. The bell mouth can cover more clinker dust, prevents plastic dust from rising, is convenient for a dust remover to pump away more clinker dust, and further reduces the pollution to the surrounding environment. After the clinker dust is pumped away by the dust remover, the clinker dust is collected in the dust remover, and purified air is discharged. Clinker dust collected in the dust separator can be recycled. The dust discharging port of the dust remover is communicated to the interior of the discharging pipeline through a dust discharging pipeline. The clinker dust discharged from the dust remover can be discharged into the truck hopper from the discharge pipeline. Or the dust discharging port of the dust remover is communicated to the feeding port of the weighing device through a dust discharging pipeline. And valves are respectively assembled on each pipeline of the clinker loading and weighing system. The corresponding pipeline can be cut off/conducted as required. Can weigh the measurement to the grog when grog loading for the freight train can once only satisfy the requirement when the weighbridge is weighed, need not to unload or the feed supplement, the limit for the load capacity of the maximize utilization freight train under the prerequisite of not overweight, avoided the waste of manpower, material resources and time.

In one embodiment, the scale body support 3 is of a frame structure.

In one embodiment, load cell 8 may accumulate the weight of the load. A force sensor for use on a load cell scale. The principle of the resistance strain type weighing sensor 8 is that the gravity acting on the measured object can be converted into a quantifiable output signal according to a certain proportion. The influence of the gravitational acceleration and the air buoyancy on the conversion in different use places, and the performance indexes of the weighing sensor 8 mainly include linear error, hysteresis error, repeatability error, creep, zero temperature characteristic, sensitivity temperature characteristic and the like. The weighing sensor 8 is classified into 8 types, such as a photoelectric type, a hydraulic type, an electromagnetic type, a capacitive type, a magnetic pole deformation type, a vibration type, a gyroscope type, and a resistance strain type, according to a conversion method, and is most widely used in the resistance strain type. The photoelectric type includes a grating type and a code disc type. The grating sensor converts the angular displacement into an optoelectronic signal by using moire fringes formed by the grating. The code disc of the code disc type sensor is a piece of transparent glass arranged on a dial shaft, and black and white codes coded according to a certain coding method are arranged on the transparent glass. The hydraulic sensor has simple and firm structure and large measuring range, but the accuracy generally does not exceed 1/100. The electromagnetic force works by using the principle that the load on the bearing platform is balanced with the electromagnetic force. The capacitor operates with a direct proportional relationship between the oscillation frequency f of the capacitor oscillation circuit and the plate spacing d. In the magnetic pole deformation mode, when the ferromagnetic element is mechanically deformed under the action of the gravity of an object to be measured, stress is generated inside the ferromagnetic element and causes the magnetic permeability to change, so that the induced voltage of secondary coils wound on two sides of the ferromagnetic element (magnetic pole) also changes along with the change. The vibration sensor has two types of vibration wire type and tuning fork type. In the use of weight sensors, strong thermal radiation, in particular one-sided strong thermal radiation, must be avoided. The load cell 8 is selected in consideration of many factors, and in practical use, we mainly consider the following factors. In addition, the sensitivity, the maximum division number, the minimum calibration division value, and the like of the load cell 8 are also indexes that must be considered in selecting the sensor. The number of the sensors is selected according to the application of the electronic weighing apparatus and the number of the points to be supported by the scale body (the number of the supporting points is determined according to the principle that the geometric center of gravity and the actual center of gravity of the scale body coincide). Generally, several sensors are selected for several supporting points of the scale body. The range selection of the sensors can be determined according to the maximum weighing value of the scale, the number of the selected sensors, the self weight of the scale body, the maximum unbalance load which can be generated and the comprehensive evaluation of the dynamic load factors. Generally, the closer the span of the sensor is to the load being distributed to each sensor, the more accurate the weighing thereof. However, in actual use, since the load applied to the sensor includes loads such as the weight of the scale body, tare weight, unbalance load, and vibration impact in addition to the object to be weighed, the sensor is selected in consideration of various factors to ensure the safety and the life of the sensor. The accuracy class of the load cell 8 includes technical indicators of sensor nonlinearity, creep, repeatability, hysteresis, sensitivity, etc. The sensor with high grade should not be pursued blindly when selecting, should consider accuracy grade and cost of electronic scale. Generally, the total accuracy of the selected sensors is a root mean square value of the sum of three indexes of nonlinearity, non-repeatability and hysteresis, which is slightly higher than the accuracy of the scale. The selection of the form of the weighing sensor 8 mainly depends on the type and the installation space of weighing, so that proper installation and safe and reliable weighing are ensured; on the other hand, the manufacturer's recommendations are considered. For sensor manufacturers, the stress condition, performance index, installation form, structural form, material of the elastic body and the like of the sensor are generally specified. For example, the aluminum alloy cantilever beam sensor is suitable for electronic valuation scales, platform scales, counter scales and the like; the steel cantilever beam sensor is suitable for electronic belt weighers, sorting weighers and the like; the steel bridge sensor is suitable for rail weighers, truck weighers and the like; the column sensor is suitable for truck scale, dynamic rail scale, large tonnage hopper scale, etc. The weighing sensor 8 is mainly applied to the fields of various electronic weighing machines, industrial control, on-line control, safety overload alarm, material testing machines and the like. Such as an electronic truck scale, an electronic platform scale, an electronic forklift, a dynamic axle weight scale, an electronic hook scale, an electronic price computing scale, an electronic steel scale, an electronic rail scale, a hopper scale, a batching scale, a canning scale and the like.
