Description

Technical Field

[0001] This application relates to the field of pesticide preparation technology, and in particular to a condensate recycling and collection device in a condensation system. Background Technology

[0002] Among pesticide products, water-dispersible granules have unique advantages over traditional formulations: they do not produce dust during use, reducing environmental pollution, ensuring safety for users, and can reduce the toxicity of highly toxic pesticides; compared with wettable powders and suspensions, they have a higher content of active ingredients, a higher relative density, and a smaller volume, making them easier to package, store, and transport; they also have better storage stability and physicochemical stability, especially for pesticides that are unstable in water, as this formulation ensures the stability of the active ingredients compared to suspensions.

[0003] In existing technologies, granulation and drying are the two most critical steps in the preparation of water-dispersible granules. Drying equipment used in pesticide preparation requires a shell-and-tube condenser to condense and cool the gas. During the gas's passage through the condenser, the moisture carried in the gas liquefies into condensate. A condensate drain pipe is connected to the bottom of the condenser for the condensate to flow out. To recycle the condensate discharged from the condenser and save production costs, a collection tank is often fixed to the condenser via a flange. The top and bottom of the collection tank are connected to an inlet pipe and an outlet pipe, respectively, and both the inlet and outlet pipes are equipped with butterfly valves to control their opening and closing.

[0004] However, when operators take cooling water from the collection tank, they often place an empty bucket under the collection tank and manually open the butterfly valve on the outlet pipe. During the condensate flow, they need to pay close attention to the water level in the bucket for a long time to prevent the condensate from overflowing. This is inconvenient and needs improvement. Utility Model Content

[0005] To improve the convenience for operators to access the condensate in the collection tank, this application provides a condensate recycling and collection device for a condensation system.

[0006] The condensate recycling and collection device for a condensation system provided in this application adopts the following technical solution:

[0007] A condensate recycling and collection device for a condensation system includes a collection tank, and:

[0008] An electric control valve is installed on the liquid outlet pipe at the bottom of the collection tank to open and close the liquid outlet pipe;

[0009] A water bucket sensing unit is fixedly installed at the bottom of the collection tank to sense the water bucket and send out a first high-level signal;

[0010] The liquid level detection unit is fixedly installed on the side wall of the liquid outlet pipe. It is used to detect the distance of the liquid level in the water tank and output a second high-level signal when the liquid level distance is greater than a set value.

[0011] The control unit is connected to the signal output terminal of the water bucket sensing unit and the liquid level detection unit, and is used to output an open control signal or an close control signal.

[0012] The signal input terminal of the electric control valve is connected to the signal output terminal of the control unit, and is used to receive the opening control signal and open the liquid outlet pipe, and to receive the closing control signal and close the liquid outlet pipe.

[0013] By adopting the above technical solution, when the operator places an empty bucket under the discharge pipe of the collection tank, the operator can activate the bucket sensing unit and the liquid level detection unit. When the bucket sensing unit senses the bucket and the liquid level detection unit measures a distance greater than a set value, the control unit automatically controls the electric control valve to open the discharge pipe, achieving the technical effect of automatically sensing the bucket and automatically opening the discharge pipe. When the liquid level in the bucket rises to a point where the liquid level detection unit measures a distance less than a set value, the control unit controls the electric control valve to close the discharge pipe, achieving the technical effect of automatically controlling the liquid level in the bucket. This eliminates the need for the operator to constantly monitor the liquid level in the bucket while using condensate, allowing the operator to perform other operations while using condensate, thus improving the convenience of using condensate.

[0014] Preferably, the water bucket sensing unit includes a connecting rod, a sensing plate, a thin-film pressure sensor, and a first comparator chip. The top of the connecting rod is fixedly connected to the body of the collection tank. The sensing plate has a first through hole for the connecting rod to pass through. The bottom end of the connecting rod is fixedly connected to an anti-detachment plate. A spring is coaxially sleeved on the connecting rod, and the spring is pressed against the collection tank and the sensing plate.

[0015] The thin-film pressure sensor is fixedly installed at the bottom of the sensing plate. The thin-film pressure sensor detects the contact pressure between the sensing plate and the top of the water bucket and outputs a sensing pressure signal.

[0016] The signal input terminal of the first comparator chip is connected to the signal output terminal of the thin-film pressure sensor. The first comparator chip receives the sensed pressure signal and outputs a first high-level signal when the sensed pressure is greater than the set pressure value.

[0017] By adopting the above technical solution, after the operator places the empty water bucket under the liquid outlet pipe, the sensing plate can be raised so that the thin-film pressure sensor at the bottom of the sensing plate contacts the top edge of the water bucket. The thin-film pressure sensor is pressed against the top edge of the water bucket by the spring, and the sensing pressure measured by the thin-film pressure sensor is greater than the set value. The first comparator chip outputs the first high-level signal.

[0018] Preferably, a limiting rod is fixedly connected to the bottom of the collection tank, and a second through-rod hole is provided through the sensing plate for the limiting rod to pass through, and one end of the limiting rod extending out of the second through-rod hole is fixedly connected to the anti-detachment plate.

[0019] By adopting the above technical solution, the limiting rod restricts the trajectory of the sensing plate, so that the sensing plate can only move up and down along the axis of the limiting rod, which can improve the stability of the sensing plate sliding up and down.

[0020] Preferably, the liquid level detection unit includes an ultrasonic ranging sensor and a second comparator chip. A mounting plate is fixedly connected to the outer wall of the liquid outlet pipe. The ultrasonic ranging sensor is fixedly mounted on the mounting plate, and the sensing end of the ultrasonic ranging sensor is set downwards.

[0021] The signal output terminal of the ultrasonic ranging sensor is connected to the signal input terminal of the second comparator chip. The ultrasonic ranging sensor detects the distance between itself and the water surface in the bucket and outputs a liquid surface distance signal. The second comparator chip receives the liquid surface distance signal and outputs a second high-level signal when the liquid surface distance is greater than a set value.

[0022] By adopting the above technical solution, the ultrasonic ranging sensor detects the distance between the liquid surface of the condensate in the bucket below the liquid outlet pipe by ultrasonic waves. When the liquid surface distance measured by the ultrasonic ranging sensor is greater than the set value, the second comparator chip outputs a second high-level signal; when the liquid level of the condensate in the bucket reaches a certain height, the liquid surface distance measured by the ultrasonic ranging sensor is less than the set value, and the second comparator chip outputs a low-level signal.

[0023] Preferably, the control unit includes a microcontroller, the signal input terminal of which is connected to the signal output terminals of the first comparator chip and the second comparator chip. The microcontroller simultaneously receives a first high-level signal and a second high-level signal and outputs an enable control signal. The microcontroller outputs an disable control signal when it does not receive the first high-level signal and / or the second high-level signal.

[0024] By adopting the above technical solution, using a microcontroller, when the operator places the induction plate on top of the water bucket and the distance to the liquid surface measured by the ultrasonic sensor is greater than the set value, it can be determined that the condensate level in the water bucket has not reached the set value. The microcontroller then controls the electric control valve to open the outlet pipe. When the condensate level in the water bucket reaches a certain height and the distance to the liquid surface measured by the ultrasonic ranging sensor is less than the set value, the second comparator chip outputs a low-level signal, and the microcontroller outputs a shutdown control signal to control the electric control valve to close the outlet pipe. This achieves the technical effect of automatically closing the outlet pipe when the condensate level in the water bucket reaches the set height.

[0025] In summary, the condensate recycling and collection device in the condensation system of this application has at least the following beneficial technical effects:

[0026] 1. When the operator places an empty water bucket under the liquid outlet pipe of the collection tank, the operator can activate the water bucket sensing unit and the liquid level detection unit. When the water bucket sensing unit senses the water bucket and the liquid level detection unit measures a liquid level distance greater than the set value, the control unit automatically controls the electric control valve to open the liquid outlet pipe, which can achieve the technical effect of automatically sensing the water bucket and automatically opening the liquid outlet pipe.

[0027] 2. When the liquid level in the water tank rises to a point where the distance between the liquid level and the liquid level detected by the liquid level detection unit is less than the set value, the control unit controls the electric control valve to close the liquid outlet pipe. This achieves the technical effect of automatically controlling the liquid level in the water tank, eliminating the need for operators to constantly monitor the liquid level in the water tank while taking condensate. It also allows operators to perform other operations while taking condensate, improving the convenience of taking condensate. Attached Figure Description

[0032] The following combination Figures 1-3 This application will be described in further detail.

[0033] Example

[0034] This application discloses a condensate recycling and collection device in a condensation system. (Refer to...) Figure 1 It mainly includes a collection tank 1, and: an electric control valve 3, installed on the liquid outlet pipe 2 at the bottom of the collection tank 1, used to open and close the liquid outlet pipe 2; a water bucket sensing unit 5, fixedly installed at the bottom of the collection tank 1, used to sense the water bucket and send a first high-level signal; a liquid level detection unit, fixedly installed on the side wall of the liquid outlet pipe 2, used to detect the distance of the liquid level in the water bucket and output a second high-level signal when the liquid level distance is greater than a set value; a control unit, connected to the signal output terminals of the water bucket sensing unit 5 and the liquid level detection unit, used to output an opening control signal or a closing control signal; and a signal input terminal of the electric control valve 3 connected to the signal output terminal of the control unit, used to receive the opening control signal and open the liquid outlet pipe 2, and receive the closing control signal and close the liquid outlet pipe 2.

[0035] When the operator places an empty bucket on the outlet pipe 2 below the collection tank 1, the operator can activate the bucket sensing unit 5 and the liquid level detection unit. When the bucket sensing unit 5 senses the bucket and the liquid level detection unit measures a distance greater than a set value, the control unit automatically controls the electric control valve 3 to open the outlet pipe 2, achieving the technical effect of automatically sensing the bucket and automatically opening the outlet pipe 2. When the liquid level in the bucket rises to a point where the liquid level detection unit measures a distance less than a set value, the control unit controls the electric control valve 3 to close the outlet pipe 2, achieving the technical effect of automatically controlling the liquid level in the bucket. This eliminates the need for the operator to constantly monitor the liquid level in the bucket while using condensate, allowing the operator to perform other operations while using condensate, thus improving the convenience of using condensate.

[0036] Reference Figure 2 and Figure 3 The water tank sensing unit 5 includes a connecting rod 51, a sensing plate 52, a thin film pressure sensor 53, and a first comparator chip. The top of the connecting rod 51 is fixedly connected to the tank body of the collection tank 1. The sensing plate 52 has a first through hole for the connecting rod 51 to pass through, and the bottom end of the connecting rod 51 is fixedly connected to an anti-detachment plate 55. A spring 54 is coaxially sleeved on the connecting rod 51, and the spring 54 is pressed between the collection tank 1 and the sensing plate 52.

[0037] A thin-film pressure sensor 53 is fixedly installed at the bottom of the sensing plate 52. The thin-film pressure sensor 53 detects the contact pressure between the sensing plate 52 and the top of the water bucket and outputs a sensed pressure signal. The signal input terminal of the first comparator chip is connected to the signal output terminal of the thin-film pressure sensor 53. The first comparator chip receives the sensed pressure signal and outputs a first high-level signal when the sensed pressure is greater than the set pressure value.

[0038] After the operator places the empty water bucket under the liquid outlet pipe 2, the sensing plate 52 can be raised so that the thin film pressure sensor 53 at the bottom of the sensing plate 52 contacts the top edge of the water bucket. The thin film pressure sensor 53 is pressed against the top edge of the water bucket by the action of the spring 54, and the sensing pressure measured by the thin film pressure sensor 53 is greater than the set value. The first comparator chip outputs the first high-level signal.

[0039] Reference Figure 2 A limiting rod 56 is fixedly connected to the bottom of the collection tank 1. A second through hole for the limiting rod 56 to pass through is provided on the sensing plate 52, and one end of the limiting rod 56 extending out of the second through hole is fixedly connected to the anti-detachment plate 55. The limiting rod 56 restricts the trajectory of the sensing plate 52, so that the sensing plate 52 can only move up and down along the axial direction of the limiting rod 56, which can improve the stability of the sensing plate 52 sliding up and down.

[0040] Reference Figure 1 and Figure 3 The liquid level detection unit includes an ultrasonic ranging sensor 6 and a second comparator chip. A mounting plate is fixedly connected to the outer wall of the liquid outlet pipe 2. The ultrasonic ranging sensor 6 is fixedly mounted on the mounting plate, and the sensing end of the ultrasonic ranging sensor 6 is set downwards.

[0041] The signal output terminal of the ultrasonic ranging sensor 6 is connected to the signal input terminal of the second comparator chip. The ultrasonic ranging sensor 6 detects the distance between itself and the water surface in the bucket and outputs a liquid surface distance signal. The second comparator chip receives the liquid surface distance signal and outputs a second high-level signal when the liquid surface distance is greater than a set value.

[0042] The ultrasonic ranging sensor 6 detects the distance between the liquid surface of the condensate in the bucket below the liquid outlet pipe 2 using ultrasonic waves. When the liquid surface distance measured by the ultrasonic ranging sensor 6 is greater than a set value, the second comparator chip outputs a second high-level signal; when the liquid level of the condensate in the bucket reaches a certain height, the liquid surface distance measured by the ultrasonic ranging sensor 6 is less than the set value, and the second comparator chip outputs a low-level signal.

[0043] In this embodiment, the control unit is a microcontroller. The signal input terminal of the microcontroller is connected to the signal output terminals of the first comparator chip and the second comparator chip. The microcontroller simultaneously receives the first high-level signal and the second high-level signal and outputs an on control signal. If the microcontroller does not receive the first high-level signal and / or the second high-level signal, it outputs an off control signal.

[0044] Using a microcontroller, when the operator places the sensor plate 52 on top of the water bucket and the distance between the liquid surface measured by the ultrasonic sensor 6 is greater than the set value, it can be determined that the condensate level in the water bucket has not reached the set value. The microcontroller then controls the electric control valve 3 to open the outlet pipe 2. When the condensate level in the water bucket reaches a certain height and the distance between the liquid surface measured by the ultrasonic ranging sensor 6 is less than the set value, the second comparator chip outputs a low-level signal, and the microcontroller outputs a shut-off control signal to control the electric control valve 3 to shut off the outlet pipe 2. This achieves the technical effect of automatically shutting off the outlet pipe 2 when the condensate level in the water bucket reaches the set height.

[0045] The implementation principle of a condensate recycling and collection device in a condensation system according to an embodiment of this application is as follows: When the operator places the induction plate 52 on top of the water tank and the liquid level distance measured by the ultrasonic sensor is greater than the set value, it can be determined that the condensate level in the water tank has not reached the set value. The microcontroller controls the electric control valve 3 to open the outlet pipe 2. When the condensate level in the water tank reaches a certain height and the liquid level distance measured by the ultrasonic ranging sensor 6 is less than the set value, the second comparator chip outputs a low-level signal, and the microcontroller outputs a shut-off control signal to control the electric control valve 3 to shut off the outlet pipe 2. This achieves the technical effect of automatically shutting off the outlet pipe 2 when the condensate level in the water tank reaches the set height.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
