Description

Technical Field

[0001] The present invention relates to the technical field related to waste liquid treatment, and in particular to a waste liquid continuous collection device. Background Art

[0002] When the waste liquid in the industrial site is discharged in a small amount, it needs to be replaced manually when the waste liquid barrel is full. If the personnel fail to replace the waste liquid barrel in time, the waste liquid is likely to overflow, causing environmental pollution and safety hazards. In addition, the manual replacement of the waste liquid barrel can only be carried out during the waste liquid discharge period, which is very likely to cause the waste liquid to splash onto the ground during the replacement of the waste liquid barrel; or the enterprise temporarily closes the discharge valve when replacing the waste liquid barrel, but this method is likely to cause excessive pressure in the pipeline and cause danger.

[0003] Invention patent content

[0004] In view of the above problems, the present invention aims to provide a waste liquid continuous recovery device. When the waste liquid is discharged through the present invention, the device can automatically switch to an empty waste liquid barrel and detect whether the waste liquid barrel is full. When the waste liquid in the industrial site is discharged in a small displacement, when the waste liquid barrel is full, it needs to be replaced manually. When the personnel do not replace the waste liquid barrel in time, waste liquid overflow is likely to occur, causing environmental pollution and safety hazards. The purpose of the present invention is achieved through the following technical solutions:

[0005] The present invention provides a waste liquid continuous collection device, which comprises a controller, a liquid collecting device, a waste liquid pipeline and a flow direction switching device, wherein the liquid collecting device comprises no less than two waste liquid barrels; the outlet end of the waste liquid pipeline is connected to the inner cavity of the waste liquid barrel; the controller is connected to the flow direction switching device, and the flow direction switching device is connected to the waste liquid pipeline, and the controller controls the flow direction switching device to drive the waste liquid flow direction to switch between different waste liquid barrels.

[0006] Furthermore, it also includes a sensing device, and the at least two waste liquid barrels are within the effective sensing range of the sensing device; the sensing device is electrically connected to the controller, and the controller controls the action of the flow direction switching device according to the information transmitted by the sensing device, thereby changing the flow direction of the waste liquid and causing the waste liquid to flow into the set waste liquid barrel.

[0007] Furthermore, the sensing device includes a positioning sensor and a liquid level sensor, the positioning sensor transmits a signal indicating whether the waste liquid barrel is in place, and the liquid level sensor transmits a signal indicating the liquid level in the waste liquid barrel.

[0008] Further, the positioning sensor includes a gravity sensor and / or a photoelectric sensor.

[0009] Furthermore, a data receiving module, a comparison module and a control output module are provided in the controller. The data receiving module receives data transmitted by the sensing device, the comparison module compares the data transmitted by the sensing device with a preset threshold, and the control output module is connected to the flow direction switching device. The controller controls the action of the flow direction switching device according to the information transmitted by the comparison module and the data receiving module.

[0010] Alternatively, a timer and an output control module are provided in the controller, the timer and the output control module are connected, and the output control module is connected to the flow direction switching device. The technical solution using a timer is usually suitable for occasions where the waste liquid discharge time and discharge volume are relatively stable. In the technical solution using a timer, a liquid level sensor may not be provided, and the waste liquid flow direction may be changed simply according to the time parameter. Alternatively, a liquid level sensor may be provided at the same time. Through the dual design of the liquid level sensor and the timer, dual stable control of the waste liquid discharge process is achieved, thereby avoiding the problem of being unable to effectively switch the waste liquid flow direction when any of the devices fails.

[0011] Furthermore, a master control valve is provided at the inlet where the waste liquid pipeline is connected to the upper pipeline, and the master control valve is connected to the controller and is opened and closed by the controller. By providing the master control valve, when the flow direction of the waste liquid is switched, the supply of waste liquid from the upper pipeline to the waste liquid pipeline can be temporarily cut off, thereby effectively preventing the waste liquid from dripping onto the ground from the gap between different waste liquid barrels during the flow direction switching process and causing pollution.

[0012] Furthermore, it also includes a base, which has a base, and the multiple waste liquid barrels are arranged on the base of the base; the collection device includes positioning sensors corresponding to the number of waste liquid barrels, the positioning sensors are fixed on the base of the base, and each waste liquid barrel is located within the effective sensing range of at least one positioning sensor.

[0013] Preferably, the flow direction switching device includes a rocker mechanism, and the waste liquid pipeline is fixedly connected to the rocker mechanism by a strap, a pipe clamp or other similar means, so that the direction of its outlet end can change with the rotation of the rocker, and the rocker mechanism is electrically connected to a controller, and the controller controls the movement of the rocker mechanism to change the direction of the outlet end of the waste liquid pipeline, so that the waste liquid can flow into different waste liquid barrels.

[0014] Furthermore, the rocker arm mechanism includes a rocker arm body and a swing cylinder, the swing cylinder is electrically connected to a controller, the first end of the swing cylinder is fixedly connected to the rocker arm body, the second end of the swing cylinder is fixed, and the swing cylinder changes the angle between the rocker arm body and the swing cylinder through its piston movement, thereby driving the waste liquid pipeline fixed on the rocker arm body to turn.

[0015] Furthermore, the first end of the swing cylinder is connected to the swing arm body by a pin-plug connection. The pin-plug connection makes the initial angle between the swing cylinder and the swing arm body and the control stroke of the swing cylinder on the swing arm body adjustable, so that adaptive adjustment can be made when the structure and layout of the waste liquid barrel change, effectively ensuring the smooth progress of the waste liquid collection process.

[0016] Furthermore, the sensing device includes a liquid level sensor, and the liquid level sensor includes an ultrasonic sensor, and the ultrasonic sensor is fixed on the swing arm body. By fixing the ultrasonic sensor on the swing arm body, when the swing arm body rotates to drive the waste liquid flow to turn, the ultrasonic sensor can turn accordingly to monitor the liquid level in the waste liquid barrel after the turn, which can reduce the number of liquid level sensors configured and save production costs.

[0017] Furthermore, the collecting device includes a base having a longitudinal support portion extending from a common gap between the at least two waste liquid barrels, and the second end of the swing cylinder is fixedly connected to the longitudinal support portion of the base.

[0018] Alternatively, a solenoid valve structure can be used instead of a rocker structure as a flow direction switching device. Specifically, the waste liquid pipeline has a plurality of branches that match the number of waste liquid barrels, and the outlet end of each branch is connected to the inner cavity of a waste liquid barrel; a solenoid valve is configured in each branch, and the solenoid valve is connected to the controller and is driven to open and close by the controller. The process of switching the flow direction of the waste liquid using this technical solution is as follows: when the controller receives a signal transmitted by the liquid level sensor of the waste liquid barrel in the current operation, indicating that the liquid level in the waste liquid barrel is close to the warning line, the controller controls the closing of the solenoid valve in the branch corresponding to the current waste liquid barrel, and at the same time opens the solenoid valve in the branch corresponding to the next waste liquid barrel that is already in place and can receive waste liquid again, so that the waste liquid flows to the branch of the newly opened solenoid valve, and the continuous collection of waste liquid is realized over and over again.

[0019] The beneficial effects of the present invention are:

[0020] (1) By configuring multiple waste liquid barrels and a flow direction switching device that can switch the waste liquid outlet to correspond to different waste liquid barrels, the waste liquid can be discharged into the waste liquid barrel with a storage space, which buys sufficient time for manual replacement of the waste liquid barrel that is full of waste liquid, and effectively avoids the risk of pollution caused by the waste liquid overflowing from the waste liquid barrel;

[0021] (2) Through the design of the sensing device and the controller, the waste liquid can flow uninterruptedly into a specific waste liquid barrel according to the set program, thus realizing the continuous collection of the waste liquid and effectively avoiding the problem of excessive internal pressure of the system caused by the long-term closure of the main valve.

[0032] Embodiment 1:

[0033] The present embodiment provides a waste liquid continuous collection device, which includes a controller 1, a liquid collecting device, a waste liquid pipeline 7 and a flow direction switching device, wherein the liquid collecting device includes no less than two waste liquid barrels, and the liquid collecting device in the illustrated embodiment includes a first waste liquid barrel 41 and a second waste liquid barrel 42; the outlet end of the waste liquid pipeline 7 is connected to the inner cavity of the waste liquid barrel; the controller 1 is electrically connected to the flow direction switching device, and the flow direction switching device is connected to the waste liquid pipeline 7, and the controller 1 controls the action of the flow direction switching device to drive the waste liquid flow direction to switch between different waste liquid barrels.

[0034] In order to fully control the timing of switching the flow direction of the waste liquid, a sensing device is also provided in the illustrated embodiment. The sensing device is electrically connected to the controller. The controller controls the flow direction switching device according to the information fed back by the sensing device. Figure 1In the illustrated embodiment, the sensing device includes a liquid level sensor 6, a first positioning sensor 31 and a second positioning sensor 32, wherein the first waste liquid barrel 41 is located within the effective sensing range of the first positioning sensor 31, and the second waste liquid barrel 42 is located within the effective sensing range of the second positioning sensor 32; the liquid level sensor 6 transmits the liquid level information in the waste liquid barrel to the controller, and the first positioning sensor 31 and the second positioning sensor 32 transmit information to the controller as to whether the corresponding waste liquid barrels are in place.

[0035] The controller 1 is provided with a data receiving module, a comparison module and a control output module. The data receiving module receives the data transmitted by the sensing device, the comparison module compares the data transmitted by the sensing device with a preset threshold, and the control output module is connected to the flow direction switching device to control the action of the flow direction switching device.

[0036] In a preferred embodiment, the positioning sensor includes a gravity sensor and / or a photoelectric sensor.

[0037] In order to effectively fix the above-mentioned multiple devices, in a preferred embodiment, a base 2 is also provided, and the base 2 has a base and a longitudinal support portion extending perpendicular to the base. In the illustrated embodiment, the first waste liquid barrel 41 and the second waste liquid barrel 42 are arranged on the base of the base 2, and the first positioning sensor 31 and the second positioning sensor 32 use photoelectric sensors, which are respectively arranged near the first waste liquid barrel 41 and the second waste liquid barrel 42; the longitudinal support portion extends from the common gap between the two waste liquid barrels so as to achieve fixation of specific components.

[0038] In the illustrated embodiment, the flow direction switching device includes a rocker mechanism 5, and the waste liquid pipeline 7 is fixedly connected to the rocker mechanism 5 by means of a strap, a pipe clamp or other similar means, so that the outlet end of the waste liquid pipeline can change its direction as the rocker mechanism 5 moves. The rocker mechanism 5 is electrically connected to a controller, and the controller controls the rocker mechanism to change the direction of the outlet end of the waste liquid pipeline. Specifically, the rocker mechanism 5 includes a rocker body 51 and a swing cylinder 52, and the swing cylinder 52 is electrically connected to the controller. The first end of the swing cylinder 52 is fixedly connected to the rocker body 51, and the second end of the swing cylinder 52 is fixed to the longitudinal support portion of the base 2. The swing cylinder 52 changes the angle between the rocker body and the swing cylinder through its piston movement, thereby driving the outlet end of the waste liquid pipeline 7 to face different waste liquid barrels, such as Figure 2 and Figure 3 shown.

[0039] In the illustrated embodiment, the first end of the swing cylinder 52 is connected to the rocker body 51 by a pin-plug connection. In other embodiments, other connection methods can also be used as long as the relative fixation between the swing cylinder 52 and the rocker body 51 can be achieved.

[0040] In a preferred embodiment, the liquid level sensor 6 includes an ultrasonic sensor, which is fixed on the rocker body 51. The ultrasonic sensor can rotate and move with the rocker, thereby monitoring the liquid level in the waste liquid barrel in a working state, saving production costs.

[0041] In the illustrated embodiment, in order to prevent waste liquid from dripping onto the ground and causing pollution during the switching of the waste liquid flow direction, a main control valve 8 is provided at the inlet where the waste liquid pipeline 7 is connected to the upstream pipeline. The main control valve 8 is connected to the controller and is opened and closed by the controller so as to temporarily cut off the waste liquid supply from the upstream pipeline to the waste liquid pipeline 7 when the waste liquid flow direction is switched, thereby reducing the risk of pollution.

[0042] The working principle of this embodiment is:

[0043] (1) System initial self-check mode: After the controller 1 and the electrical components are powered on, the controller 1 detects whether the first waste liquid bucket 41 and the second waste liquid bucket 42 are in place through the first positioning sensor 31 and the second positioning sensor 32. If both the first waste liquid bucket and the second waste liquid bucket are in place, the controller 1 drives the swing arm body 51 to the top of the first waste liquid bucket 41 through the swing cylinder 52.

[0044] (2) Waste liquid discharge process: The waste liquid flows to the first or second waste liquid barrel through the waste liquid pipeline 7 fixed on the swing arm structure 5, and the liquid level sensor 6 monitors in real time whether the corresponding waste liquid barrel is full. If the current liquid level barrel is full, the controller 1 drives the swing arm body 51 to swing to the top of the other side liquid level barrel through the swing cylinder 52, and repeats the cycle.

[0045] For this embodiment 1, the following points need to be explained:

[0046] (1) Although the illustrated embodiment shows a design of two waste liquid barrels, the design of the present invention is not intended to have only two waste liquid barrels. When necessary, more waste liquid barrels can be designed. As long as the sensors are set according to the method of this embodiment and the parameters of the controller controlling the rocker mechanism are changed, the flow direction of the waste liquid can be switched between multiple waste liquid barrels.

[0047] (2) The working logic of the controller in this embodiment is to compare and judge the multiple parameters involved in the signal with the preset threshold values ​​of the corresponding parameters after reading the signal transmitted by the sensing device, and then control the rocker cylinder to move to a specific position according to the judgment result, so that the waste liquid can flow into the set waste liquid barrel; however, when designing the invention, the inventor of the present invention has also considered that in some industrial practices where the discharge time and discharge volume of waste liquid are relatively stable, the role of the liquid level sensor is not completely necessary. It can achieve timed directional control of the rocker cylinder to move to a specific position by setting a timer in the controller, which can also achieve the purpose of the present invention. Moreover, in other practices, the dual design of the timer and the liquid level sensor can also be used to achieve dual stable control of flow direction switching, fully ensuring the safety of waste liquid discharge.

[0048] Embodiment 2:

[0049] The basic principle of this embodiment is similar to that of embodiment 1, except that, in this embodiment, the flow direction switching device adopts a solenoid valve structure, and the waste liquid pipeline has outlet ends that match the number of waste liquid barrels, and each outlet end is connected to the inner cavity of a waste liquid barrel; each outlet end is equipped with a solenoid valve, which is connected to the controller and driven to open and close by the controller. In this embodiment, there is no need to set a rocker mechanism. When it is necessary to switch the waste liquid barrel that receives the waste liquid, the controller controls the solenoid valve at the outlet of the waste liquid pipeline corresponding to the waste liquid barrel that is being filled and the liquid level is at the warning line position to close, and then opens the solenoid valve at the outlet of the waste liquid pipeline corresponding to the empty waste liquid barrel that is in place, so as to realize the switching control of the flow direction of the waste liquid.

[0050] At the same time, the setting of fixing the ultrasonic sensor on the rocker mechanism in Example 1 is not applicable to this embodiment. In this embodiment, multiple ultrasonic sensors or other types of liquid level sensors can be used and fixed on each waste liquid barrel or waste liquid pipeline.

[0051] In addition, in the technical solution of this embodiment 2, a main control valve may not be provided, because the multiple branch outlet ends of the waste liquid pipeline directly correspond to a waste liquid barrel, and the waste liquid flow direction switching process is carried out inside the pipeline, and the waste liquid will not drip onto the ground.

[0052] Embodiment 3:

[0053] The basic principle of this embodiment is the same as that of Embodiment 1 and Embodiment 2. The technical solution of this embodiment 3 is to combine the technical solutions of Embodiment 1 and Embodiment 2 together, that is, the waste liquid pipeline has fewer branches than the number of waste liquid barrels, such as half or less of the number of waste liquid barrels, and a rocker mechanism is correspondingly arranged on each branch, so that the switching of the waste liquid flow direction is achieved through the joint adjustment of the rocker mechanism and the solenoid valve.

[0054] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention. The dimensions described in the drawings and embodiments are not related to the specific objects and are not used to limit the protection scope of the present invention. The dimensions of the objects can be selected and changed according to actual needs.
