Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of funnels, and in particular relates to a funnel device. Background Art
[0002] Funnels are often used to transfer materials, especially into small-bore containers. When the target container already contains different materials, the addition of new materials can cause changes in the system, such as heat release and gas generation. This can occur during processes like adding reactants to a chemical reaction system, mixing different substances, or recovering multiple waste streams. If these changes are dramatic, the material in the container can backflush out of the funnel, causing injury to the operator and property damage. Summary of the Invention
[0003] In order to solve the problems existing in the background technology, the purpose of the present invention is to provide a funnel device with a simple structure and ingenious design, which can issue an early warning of possible dangers during the feeding process and protect the operator when flushing.
[0004] For this purpose, the present invention adopts the following technical solutions.
[0005] The utility model provides a funnel device, which comprises a funnel cavity, a feeding channel, a recoil cavity and a recoil channel; the feeding channel is connected below the funnel cavity, a one-way valve is arranged in the feeding channel, the recoil cavity is located outside the feeding channel and is not connected with the feeding channel, the recoil channel is arranged outside the funnel cavity and is not connected with the funnel cavity, and the recoil cavity is connected with the recoil channel.
[0006] In the utility model, a check valve is installed on the recoil channel.
[0007] In the utility model, an alarm device is installed on the side of the funnel cavity, and the alarm device is connected to a sensor. The sensor is used to test one or more of the temperature, pressure, conductivity, potential, pH value, optical rotation or refractive index information in the target container to which the funnel device adds material.
[0008] In the present invention, the sensor is at least one of a temperature sensor, a pressure sensor, a conductivity sensor, a potential sensor, a pH sensor, an optical sensor or a gas sensor.
[0009] In the utility model, the outer connecting device of the recoil chamber connects the funnel device and the target container for adding materials, and forms a seal with the target container.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] When the material is added to the target container from the funnel cavity, the sensor at the bottom of the funnel detects the material status in the target container in real time. When the measured value exceeds the limit, an alarm is issued, and the operator can take timely countermeasures such as slowing down the feeding speed or stopping the feeding. When the target container undergoes drastic changes and causes material backflushing, the one-way valve of the feed channel is closed, and the material is discharged from the backflushing channel through the backflushing cavity to protect the safety of the operator.

[0017] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
[0018] See also Figures 1 to 4 A funnel device includes a funnel chamber 1, a feeding channel 2, a one-way valve 3, a backflushing chamber 4, a backflushing channel 5, a connecting device 6, an alarm device 7 and a sensor 8.
[0019] The funnel chamber 1 is a downward-opening conical structure. The lower part of the funnel chamber 1 is connected to the feed channel 2, and a one-way valve 3 is provided inside the feed channel 2; the backwash chamber 4 is located outside the feed channel 2 and is not connected thereto, and the backwash channel 5 is located outside the funnel chamber 1 and is not connected thereto, and the backwash chamber 4 is connected to the backwash channel 5; a check valve is provided in the backwash channel 5, so that the material can only be discharged from the target container through the backwash chamber 4 and cannot return.
[0020] The connecting device 6 is located outside the backflushing chamber 4 and has specifications that match the target container. The connecting device 6 can be a thread, a piston, or a buckle structure that matches the target container.
[0021] Alarm device 7 is located above and outside funnel chamber 1 and is connected to sensor 8 via a wire. Sensor 8 is located below recoil chamber 4 and can be at least one of a temperature sensor, pressure sensor, conductivity sensor, potential sensor, pH sensor, optical sensor, gas sensor, or other sensor that captures system state parameters. Alarm device 7 is powered by a battery.
[0022] The working principle of this utility model is as follows:
[0023] During use, the sensor 8, the feed channel 2, and the lower portion of the backwash chamber 4 are inserted into the target container. The sensor 8 contacts the material in the target container, the connecting device 6 is fixed to form a seal with the target container, the alarm device 7 is powered on, and material is added through the funnel chamber 1. At this time, the one-way valve 3 is in the open state, and the material enters the target container through the feed channel 2. When the material parameters in the target container exceed the limit value, the alarm device 7 will sound an alarm, and the feeding speed can be slowed down or stopped. When the material in the target container changes drastically, causing material backwash, the one-way valve 3 is closed, and the material is discharged from the backwash channel 5 through the backwash chamber 4. The utility model can issue a warning of possible dangers during the feeding process and protect the operator when backwashing occurs.
