Description

Technical Field

[0001] The utility model belongs to the field of dust suppression equipment, and particularly relates to a closed dust suppression device for an electronic batching scale. Background Technique

[0002] As a modern weighing device, the electronic batching scale has been widely used in many industries such as metallurgy, building materials, chemical industry, and food, and has become an indispensable part of these industries to accurately weigh and feed various bulk materials, thus ensuring the continuity and stability of the production process.

[0003] At present, in practical applications, the electronic batching scale is usually installed at a position 150 - 200 mm above the belt conveyor. Such a design can ensure that the material can accurately fall into the conveyor, and at the same time is conducive to the accurate weighing operation of the electronic batching scale to ensure that it can evenly feed the belt conveyor under the control of the automatic control system, greatly improving production efficiency and accuracy.

[0004] However, during the feeding process, due to the collision and friction of the material, a large amount of dust is often generated. Especially when dealing with powdery materials, the problem of dust flying is particularly prominent. These dusts will not only pollute the environment but also pose a threat to the health of workers. Therefore, in the industrial production process, it is particularly important to solve the problem of dust flying. Content of the Utility Model

[0005] The technical problem solved by the utility model is to provide a closed dust suppression device for an electronic batching scale that can effectively solve the dust hazard at the feeding point of the electronic batching scale above the conveyor, so as to significantly reduce the dust flying at the feeding point of the electronic batching scale and protect the environment and the health of workers.

[0006] To solve the above technical problem, the technical solution provided by the utility model is: a closed dust suppression device for an electronic batching scale, including a dust suppression cover that can cover the electronic batching scale and the belt conveyor. A spray assembly is installed inside the dust suppression cover. An observation window for the electronic batching scale is provided on the front or rear side of the dust suppression cover, and a wiping assembly is installed at the observation window for the electronic batching scale. Dust-proof curtains are installed at the conveyor belt passing windows provided on the left and right sides of the dust suppression cover. In this way, when the utility model is installed outside the electronic batching scale and the corresponding belt conveyor, on the one hand, it can prevent dust from flying out of the dust suppression cover through the dust suppression cover and the dust-proof curtains to protect the environment and the health of workers; on the other hand, it can perform dust reduction treatment on the dust inside the dust suppression cover through the spray assembly, and through the cooperation of the observation window for the electronic batching scale and the wiping assembly installed at the observation window for the electronic batching scale, ensure that the staff can clearly observe the working state of the electronic batching scale to ensure the continuity and stability of the production process.

[0007] Furthermore, a maintenance door is provided on the front or rear side of the dust suppression cover, and staff can enter the interior of the dust suppression cover through this maintenance door to repair the belt conveyor or the electronic batching scale.

[0008] Furthermore, a dust concentration monitor is provided inside the dust suppression cover. The dust concentration monitor is electrically connected to an alarm lamp, and the alarm lamp is installed on the outside of the dust suppression cover. In this way, the utility model can monitor the dust concentration inside the dust suppression cover in real time through the dust concentration monitor, and transmit a signal to the alarm lamp when the monitored dust concentration exceeds the standard, controlling the alarm lamp to give a warning to remind the staff that it is not suitable to enter the dust suppression cover at this time.

[0009] Furthermore, the spray assembly includes spray nozzles installed inside the dust suppression cover. The spray nozzles are connected to a water pump through a first water delivery pipe. The water pump is connected to a water tank through a second water delivery pipe. The water pump is electrically connected to a controller through a cable. The controller is preferably a pulse controller, and can control each spray nozzle to be turned on once every 60 seconds through this pulse controller, with each continuous spray lasting for 10 seconds to achieve the dust suppression effect.

[0010] Furthermore, the wiping assembly includes an active wiping head provided on the outside of the observation window of the electronic batching scale and a passive wiping head provided on the inside of the observation window of the electronic batching scale. An active adsorption magnet is installed inside the active wiping head, and an active wiping cloth is provided on the side of the active wiping head opposite to the observation window of the electronic batching scale; a passive adsorption magnet is installed inside the passive wiping head, and the passive adsorption magnet adsorbs with the active adsorption magnet; a passive wiping cloth is provided on the side of the passive wiping head opposite to the observation window of the electronic batching scale, and this passive wiping cloth can wipe the inside of the electronic batching observation window when the active wiping head drives the passive wiping head to move, so as to ensure that the staff can clearly observe the working condition of the electronic batching scale inside the dust suppression cover.

[0011] Furthermore, one side of the observation window of the electronic batching scale is hinged to the dust suppression cover through a hinge, and the other side of the observation window of the electronic batching scale is locked to the dust suppression cover through a door and window locking mechanism. In this way, in some special cases, the staff can open the observation window of the electronic batching scale to perform corresponding operations on the electronic batching scale.

[0012] From the above technical solutions, it can be seen that the utility model has the following advantages: on the one hand, it can prevent dust from flying out of the dust suppression cover through the dust suppression cover and the dust-proof curtain to protect the environment and the health of workers; on the other hand, it can perform dust reduction treatment on the dust inside the dust suppression cover through the spray assembly, and through the cooperation of the observation window of the electronic batching scale and the wiping assembly installed at the observation window of the electronic batching scale, ensure that the staff can clearly observe the working state of the electronic batching scale to ensure the continuity and stability of the production process.
