DETAILED DESCRIPTION

[0022] For further details of the utility model, next in combination with the drawings is explained. It is particularly pointed out that the examples described below are only a part of the utility model embodiments, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the scope of the utility model protection.

[0023] Reference Figure 1 As shown in the utility model provides a kind of enzyme preparation metering equipment, including a base 1, the base 1 is equipped with a storage tank 2 for storing liquid enzyme preparation and a diaphragm metering pump 3.The storage tank 1 is also equipped with a control device 7, and the control device is electrically connected with the diaphragm metering pump 3.

[0024] Specifically, as shown in the utility model Figure 1 And Figure 2 As shown in the utility model, the bottom of the storage tank 2 one side is equipped with a discharge port 4, the discharge port 4 is connected with the diaphragm metering pump 3 by a first pipeline 5, and the discharge port 4 is equipped with a flow meter 6;The flow meter 6 is used to detect the flow of liquid enzyme in the first pipeline 5;The other end of the diaphragm metering pump 3 is connected with a discharge pipeline (not shown in the figure).The flow meter 6 is electrically connected with the control device 7.The electrical connection of flow meter 6 and control device 7 enables control device 7 to obtain flow data in time, and adjusts the working state of diaphragm metering pump 3 according to the need, so as to realize the accurate control of liquid enzyme flow.

[0025] When using the equipment to add enzyme preparation, the diaphragm metering pump 3 starts to extract the liquid enzyme inside the storage tank 2, and when the liquid enzyme flows through the first pipeline 5, the flow meter 6 will monitor its flow in real time, and the measurement result will be converted into an electrical signal and transmitted to the control device 7. After obtaining the flow data according to the electrical signal, the control device 7 will be processed and analyzed in real time, and the running frequency of the diaphragm metering pump 3 will be adjusted according to the current demand of liquid enzyme, so as to realize the accurate metering of liquid enzyme. In the whole metering process, the control device 7 will continuously receive the feedback data of the flow meter 6, and automatically fine-tune the running frequency of the diaphragm metering pump 3 according to the actual situation, so as to determine whether the flow of the current liquid enzyme meets the set requirements.

[0026] The inside wall of the top of the storage tank 3 is provided with a spray pipe 8 through a plurality of fixing blocks (not marked in the figure), and a plurality of spray heads 9 are arranged on the spray pipe 8;The top of the storage tank 3 is provided with a water inlet pipe 10 for cleaning liquid to enter the storage tank 3 and a feed inlet 11 for adding liquid enzyme to the storage tank 3, and the water inlet pipe 10 is communicated with the spray pipe 8.In this embodiment, a cover 101 is arranged on the feed inlet 10;An electromagnetic valve 111 is arranged on the water inlet pipe 11.

[0027] When the storage tank 3 needs to be cleaned, the cleaning liquid enters the spray pipe 8 in the storage tank 3 through the water inlet pipe 10, and the spray heads 9 on the spray pipe 8 uniformly spray the cleaning liquid in the form of mist or fine stream to the inner wall and bottom of the storage tank 3, forming a wide cleaning layer in the storage tank 3, and the residual in the tank is preliminarily cleaned at the same time. In this embodiment, the cleaning liquid is tap water or tap water with cleaning agent added.

[0028] Referring to Figure 2 and Figure 3 , the storage tank 3 is also provided with a stirring mechanism; the stirring mechanism includes a drive motor 14 arranged at the top of the storage tank 3 and a rotating shaft 15 arranged in the storage tank 3, the rotating shaft 15 is connected with the output shaft of the drive motor 14, and a plurality of stirring blades 16 are symmetrically arranged on both sides of the rotating shaft 15. The drive motor 7 is electrically connected with the control device 7.

[0029] When the liquid enzyme preparation enters the storage tank 3 through the feed port 11, the drive motor 14 can be started at regular intervals to drive the rotating shaft 15 connected thereto to rotate, and the stirring blades 16 on the rotating shaft 15 agitate the liquid enzyme preparation with the rotation of the rotating shaft 15, ensuring uniform distribution of the liquid enzyme preparation in the storage tank 3, which helps to prevent stratification, precipitation or crystallization of the liquid enzyme preparation, and maintains its uniformity and stability.

[0030] When the cleaning liquid is introduced into the storage tank 3 for cleaning, the rotating stirring blades 16 form vortex or turbulent flow in the storage tank 3, thereby enhancing the fluidity and diffusivity of the liquid, so that the cleaning liquid can more fully contact each part of the tank body, significantly improving the cleaning efficiency and ensuring that the interior of the tank body is fully and thoroughly cleaned.

[0031] In some embodiments, the stirring blade 16 includes a fixed rod 161 horizontally arranged on the rotating shaft 15 and a stirring plate 162 arranged on the fixed rod 161, the stirring plate 162 is provided with through holes 163, and the stirring plate 163 is also provided with reinforcing ribs 164. The through holes 163 can reduce the resistance of the stirring plate 162 in the cleaning liquid, while increasing the speed of the cleaning liquid passing through. When the stirring blade 16 rotates, the liquid can pass through the stirring plate 162 more smoothly, forming stronger vortex and turbulent flow, further improving the stirring effect. The reinforcing ribs 164 can significantly improve the overall structural strength of the stirring blade 16 and prolong the service life.

[0032] The storage tank 3 is provided with at least one ultrasonic generator 12 outside, and a plurality of vibration contacts 13 are arranged on the inner wall of the storage tank 3 and electrically connected with the ultrasonic generator 12; the ultrasonic generator 12 is used to drive the connected vibration contacts 13 to generate ultrasonic vibration on the cleaning liquid in the storage tank 3.

[0033] When the cleaning liquid in the storage tank 3 reaches the preset liquid level, the ultrasonic generator 12 is started, and the ultrasonic generator 12 drives the vibration contacts 13 to generate ultrasonic vibration and transmit it to the cleaning liquid entering the storage tank 3. When the ultrasonic wave propagates in the cleaning liquid, cavitation effect is generated, which can generate strong impact force on the cleaning liquid, effectively stripping the dirt, residues and the like on the surface of the tank body and in the liquid. At the same time, the ultrasonic wave propagating in the cleaning liquid also forms micro-jets, which can penetrate the micro-gaps and dead angle areas in the liquid, ensuring that the tank body and the liquid are fully and thoroughly cleaned.

[0034] The ultrasonic cleaning effect formed by the ultrasonic generator 12 and the vibration contacts 13 effectively strips and disperses the residues attached to the inner wall and bottom of the storage tank, and further cooperates with the stirring mechanism to agitate the cleaning liquid, greatly improving the cleaning efficiency.

[0035] In some embodiments, the storage tank 3 is also provided with a hot air pipe 17 and an exhaust pipe 18 on one side, the hot air pipe 17 is connected with a hot air machine (not shown in the figure), and the hot air machine 17 is used to deliver high-temperature drying gas into the storage tank.

[0037] In some embodiments, a temperature sensor 19 for detecting the temperature in the storage tank 3 is installed in the storage tank 3. The temperature sensor 19 is electrically connected with the control device 7. Through the real-time detection of the temperature sensor 19, the storage tank 3 can be stored after drying at an appropriate temperature, and the temperature change can be monitored in real time during storage, so as to ensure that the liquid enzyme preparation is stored at an appropriate temperature.

[0038] In some embodiments, a magnetic float liquid level gauge 20 for detecting the liquid level in the storage tank 3 is also arranged in the storage tank, so as to master the change of the liquid level in the storage tank in real time.

[0039] In some embodiments, an observation window 21 is also arranged on the storage tank 3, so as to facilitate the observation of the inside of the storage tank 3.
