Description

Alarm and protection device for preventing protein separator from exploding and rushing

Technical Field

The utility model relates to the technical field of aquaculture device control, in particular to an alarm and protection device for preventing a protein separator from exploding and rushing.

Background

The protein separator, also called egg separator, is an indispensable device for maintaining the normal operation of the seawater tank for a long time, and can remove harmful organic substances out of the seawater tank to prevent the water quality from deteriorating.

The egg separation principle is as follows: the principle of utilizing the surface tension of bubbles in water to adsorb various granular dirt and soluble organic matters mixed in water is adopted, an oxygenating device or a vortex pump is adopted to generate a large amount of bubbles, seawater passing through a protein separator is purified, the bubbles are all concentrated on the water surface to form foam, the foam adsorbing dirt is collected in a container on the water surface, and the foam is converted into turbid liquid to be discharged. The contact surface of the protein separator is similar to the surface between air and water. For example, the contact surface formed by the water surface of an aquarium has a certain surface tension, so that cellulose, protein and food residues are inevitably accumulated thereon. In fact, if the surface area is enlarged, for example bubbles are generated (foam is produced), more cellulose, protein and food residues are naturally formed on the surface. The viscosity of the foam will change as the surface strengthens and enlarges, and the bubbles gradually disappear. The effectiveness of a protein separator is therefore to enlarge the surface area between gas and liquid and its specific surface tension. However, the foam generated is separate from the discharge of the water circulation in the aquarium, which is why the foam can be used directly to remove waste from the aquarium.

The reason for causing the egg burst is mainly caused by the following two conditions:

1) the artificial filter material contains a surfactant, has a foaming effect, is applied to a water body, and increases the foaming amount when egg is used for treating water quality, so that burst is caused;

2) oily substances are contained in the inner pipes of other seawater equipment, such as a submersible pump, a water chiller and the like, so that the egg score is unstable in foaming and explosion is caused.

When the egg is exploded, a large amount of foam for absorbing dirt is generated in the egg, so that turbid liquid in the foam collecting volume is rapidly increased, and the water level in the container is continuously increased. If the egg separation operation is not stopped in time, the sewage overflows the collecting container, flows into a cabinet for mounting the egg separation and on the ground, and can influence the normal operation of the sea vat.

Detailed Description

The following describes in detail specific embodiments of the present invention. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

Example 1

Fig. 1 shows an embodiment of the alarm and protection device for preventing protein separator explosion according to the present invention, which comprises a detection unit, a relay output unit, a main control unit, an operation unit, a wireless unit, an alarm unit and a power supply unit. The relay output unit, the main control unit, the operation unit, the wireless unit, the alarm unit and the power supply unit main control unit in the device can be integrated into a circuit board and designed to be integrated with a 220V socket.

In this embodiment, the detection unit is configured to detect a water level of the protein separator and transmit detection data to the main control unit. The main control unit is electrically connected with the detection unit, the relay output unit, the operation unit, the wireless unit, the alarm unit and the power supply unit and used for receiving signals and sending instructions. The relay output unit is electrically connected with the power supply unit and used for controlling the power supply unit. The main control unit controls the egg separator to start and stop through the relay output unit. The main control unit sends signals to an external server and a user APP through the wireless unit. The operation unit is used for resetting the main control unit. The alarm unit sends out an alarm signal according to the instruction of the main control unit. The power supply unit supplies power to the device and the protein separator.

In the embodiment, the device is provided with a shell, the shell 4 is similar to a commonly used intelligent socket at present, one surface of the shell 4 is provided with a plug which can be directly plugged into a 220V household power socket to supply power to the device and supply power to a power supply unit through a relay output unit; the egg power supply unit is inserted into the socket of the device, and on-off control of the power supply unit is realized through the relay output unit. The power supply unit supplies power to the device and the protein separator.

In this embodiment, the device of this embodiment adopts the mode of contactless detecting element, and the detecting element includes level sensor 3, and level sensor 3 installs in egg branch foam collecting container 1 department, and level sensor 3 is connected with other unit electricity, realizes level sensor 3's power supply and feeds back water level information for the main control unit. When the waste water in the foam collecting container 1 reaches a set water level, the waste water is required to be poured in time to prevent the waste water from overflowing, and the collecting container for egg separation is generally set to be convenient for a user to dismantle and pour the waste water. This embodiment adopts contactless water level sensor 3, is about to install water level sensor 3 at the lateral wall of foam collection container 1 through a fixed baseplate 2, and water level sensor 3 can dismantle with fixed baseplate 2 and be connected, and fixed baseplate 2 can bond at 1 lateral wall of foam collection container. When the user is clearing up the container sewage, tear down water level sensor 3 and can separate with the container. The mounting height of the fixed base 2 is close to the upper edge of the foam collecting container 1, and a certain safety margin is required. The horizontal central line of the fixed base 2 is the maximum safe threshold of the safe water level height of the water level sensor 3, namely the set water level detected by the water level sensor 3.

The contactless water level sensor 3 of the present embodiment operates on the principle of sensing the presence or absence of liquid using an inductive capacitor, when no liquid is close to the water level sensor 3, the water level sensor 3 has a certain static capacitance to the ground due to the distributed capacitance, when the liquid level rises slowly and approaches the water level sensor 3, the parasitic capacitance of the liquid will be coupled to the static capacitance, so that the capacitance value of the water level sensor 3 becomes larger, the changed capacitance signal is input into the control chip for signal conversion, the changed capacitance is converted into the variable quantity of a certain electric signal, the degree of the variable quantity is detected and judged by the data processing algorithm in the prior art, when the variation exceeds a certain threshold, the liquid level is considered to reach the sensing point, and whether the liquid is detected or not can be indicated by the variation of the output level. For example: when the liquid level is lower than the set water level height, the water level sensor 3 outputs a low level; when the liquid level is equal to or higher than the set water level height, the water level sensor 3 outputs a high level.

The water level in the foam collecting container 1 can reach the set water level detected by the water level sensor 3 under two conditions, firstly, eggs work normally, the collected wastewater can slowly increase, and when the water level is increased to the set water level, a user needs to clean the eggs; secondly, the water level can be rapidly raised to the set water level when the explosion and impact fault occurs. In both cases, the egg should be stopped as soon as the water level reaches the level set by the water level sensor 3, to prevent the water level from rising further and overflowing the container.

In this embodiment, the output signal of the water level sensor 3 is connected to the IO port of the main control unit, and the main control unit can determine whether the water level in the foam collecting container 1 reaches the set height by regularly inquiring the level of the water level sensor 3.

In this embodiment, the relay output unit is controlled by the main control unit and is used for realizing on-off control of the power supply unit. When the main control unit outputs an effective control level (such as a high level), the coil of the output relay is electrified, the normally open contact of the relay is closed, the egg work power supply is switched on, and the egg separator starts to work; when the main control unit outputs an invalid control level (such as a low level), the relay coil loses power, the normally open contact of the relay is disconnected, the egg work power supply is disconnected, and the egg stops working.

The main control unit adopts a single chip microcomputer as a control core, queries and logically judges the input port corresponding to the water level sensor 3 at regular time, for example, when the level of the port is low, if the level is lower than the set level, the effective control level is maintained to be output to the relay, and the normal work of the egg separator is ensured; when the received level of the port is high level, if the water level is equal to or higher than the set water level, an invalid control level is output to the relay, the egg separator stops working, and meanwhile, local alarm is triggered, so that the buzzer buzzes to remind a user.

In this embodiment, the main control unit has a function of delayed start. Generally, when the sea-vat equipment is restarted, the protein separator needs to be started after a delay after the main pump is started, otherwise, the explosion and rush can occur because the water level of the bottom vat is too high. The main control unit control device can operate a section of time delay program after the sea tank equipment is restarted by matching with the protein separator, the main control unit can output an invalid level to the relay output unit in the time delay process, the egg score can be guaranteed to stop working in the period, and the valid level can be output to the relay output unit until the time delay is finished, so that the egg score is started. The delay time is approximately 50% of the drop in the water level in the bottom tank, and the delay process can be ended.

The main control unit is communicated with the wireless unit in the operation process, and the main control unit sends the received data information of the water level sensor 3 to a user mobile phone or other displays through the wireless unit, so that remote burst alarming is realized. Be provided with control chip in the wireless unit, and can both carry out secondary development, the wireless unit can adopt ESP8266 series WIFI unit, can realize the master control unit and the function of wireless unit is unified.

In this embodiment, the operation unit includes an alarm reset button, and the alarm reset button is connected with the port of the main control unit chip and is used for resetting the water level alarm information. When the water level sensor 3 detects that the sewage in the protein separator foam collecting container 1 reaches a preset water level, the main control unit outputs an invalid level to the relay output unit, and the working power supply of the egg is cut off to prevent the water level from further rising. This inactive level will remain until the user presses the alarm reset button. After the user processes the explosion and impact fault or cleans the collecting container, the alarm can be reset through the alarm reset key, and after the reset, the main control unit outputs an effective level to the relay output unit to start egg separation.

In this embodiment, the alarm unit may be in the form of a sound signal or a light signal, and if the alarm unit is a light signal, the light signal is disposed outside the housing 4. When the water level sensor 3 detects that the sewage in the foam collecting container 1 reaches a preset water level, the main control unit outputs an alarm control signal and reminds a user in an audible and visual alarm mode, so that the user can timely handle faults or clean the collecting container.

Example 2

Fig. 2 shows a second embodiment of the alarm and protection device for preventing the protein separator from bursting, which is different from example 1 in that a floating ball type water level sensor 3 is used. The water level sensor 3 floats on the liquid surface of the foam collecting container 1. The floating ball 31 changes along with the change of the liquid level due to the buoyancy effect, the permanent magnet is placed in the floating ball 31, when the liquid level rises to a certain position, the permanent magnet in the floating ball 31 can trigger a magnetic reed switch in the water level sensor, and the permanent magnet is matched with a certain circuit to generate a level change. For example: when the liquid level is normal, the position of the floating ball 31 is lower, the magnetic reed switch is disconnected because the magnetic reed switch is far away from the permanent magnet, and high level is output; when the liquid level exceeds the limited water level, the position of the floating ball 31 rises, the magnetic reed switch is closed because of being close to the permanent magnet, and low level is output; the level change is input to a water level detection port of the main control unit through a signal line, and the main control unit judges whether the water level reaches the detection water level by inquiring the level change of the port.
