Description

Technical Field

[0001] This utility model relates to the technical field of powder material metering equipment in the industrial sector, specifically to an online calibration and feeding device. Background Technology

[0002] Metering systems are key equipment in cement production processes, and their metering accuracy directly affects product quality and production cost control. However, the calibration of existing metering scales has always faced many technical challenges: traditional calibration methods require production to be stopped, the metering scale must be disassembled after unloading, and the material must be transferred to a designated container for weighing and calibration, which seriously affects the continuity of production; traditional calibration disassembly and assembly work is complex and cumbersome, the disassembly technology is difficult, and the calibration cycle is long, making it impossible for production enterprises to perform calibration regularly. As a result, the metering scale operates in a state of error for a long time, which is not conducive to cost control and product quality improvement.

[0003] Therefore, there is an urgent need for a simple and convenient method to calibrate weighing scales on-site, solving the technical problem of calibrating weighing scales without interrupting production. In view of this, we propose an online calibration and feeding device. Utility Model Content

[0014] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Please see Figure 1 The present invention will describe the above technical solution in detail through the following embodiments: The online calibration feeding device of this embodiment includes a Coriolis scale 2, which is the core of the metering system and has an inlet 1 and a outlet 3. In order to achieve online calibration, there is no need for complicated disassembly and assembly. This application has a calibration feeding part that can be detachably installed below the outlet 3.

[0016] Specifically, it includes a discharge chute 4 that can be detachably installed below the discharge port 3 via a flange. In this embodiment, the discharge chute 4 is vertically arranged, and a conveying chute 8 for conveying powder is installed at the bottom of the discharge chute 4. In other embodiments, a terminal conveying device such as a pneumatic conveying pump can be installed. In order to obtain the calibration function, a dual-channel chute is designed, and a calibration chute 5 for calibration purposes is provided on the discharge chute 4.

[0017] In order to independently perform the calibration and feeding functions, this embodiment has a feeding gate valve 6 and a calibration gate valve 7 detachably installed on the feeding chute 4 and calibration chute 5, respectively, as gates. Electric gate valves are used to realize automated control.

[0018] It should be explained that this application achieves rapid switching between the two chutes through an electric gate valve, which is simple and reliable to operate. When calibrating the material discharge, the calibration chute 5 discharges the powder into the calibration container for calibration. The calibration is performed by comparing the mass data discharged into the calibration container with the weighing data of the weighing scale 2. In order to reduce calibration error, the positions of the discharge gate valve 6 and the calibration gate valve 7 need to be limited. That is, the discharge gate valve 6 and the calibration gate valve 7 are respectively set near the bottom of the connection between the discharge chute 4 and the calibration chute 5 to reduce material accumulation. In actual application, errors in material conveying are allowed. Other embodiments can install a gas flow aid device or an air hammer at the connection between the discharge chute 4 and the calibration chute 5 to avoid material accumulation and further reduce calibration error.

[0019] The working principle of this application is as follows: During normal production, the discharge gate valve 6 is opened and the calibration gate valve 7 is closed. The material enters the downstream equipment through the normal discharge chute 4 to complete the material conveying. When calibration is required, the calibration gate valve 7 is opened and the material is discharged through the calibration chute 5 and collected into the calibration container. After weighing, the data is recorded, and the coefficient is corrected according to the actual weight and the reading of the weighing scale to achieve online calibration.

[0020] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
