Detailed Description
The following detailed description of the embodiments of the present invention is provided in connection with the accompanying drawings for the purpose of understanding and controlling the technical solutions of the present invention, so as to define the protection scope of the present invention more clearly.
The invention provides a connecting device which is innovated by designers aiming at the defects of the existing sludge treatment station in the aspect of infrastructure, in particular to the defects that the cost of construction, sealing, operation and maintenance and the like of a sludge unloading room is high, relies on long-term production line experience, and can ensure that a sludge vehicle can be directly butted with a wet sludge bin so as to improve the sludge transportation efficiency and prevent pollutants from overflowing at low cost.
As shown in fig. 1 and 2, the connecting device 3 of the present invention is integrally positioned and attached to the ground where the sinking type wet sludge bin 2 is located, and is a facility which is wholly in a fixed state and is partially exposed to the outside. From the structural characteristics of the device in summary, the device mainly comprises a sealing steel pipeline 31, an exhaust gas drainage pipe 32, a vacuum pump 33, a sealing canvas cover and a rubber air bag 35, wherein the lower end of the sealing steel pipeline 31 is connected and communicated with the wet sludge bin 2, the upper end of the sealing steel pipeline is connected and communicated with the sealing canvas cover, and the sealing steel pipeline is integrally formed into a channel for discharging sludge to the wet sludge bin. Because the inner cavity of the device is directly communicated with the wet sludge bin, negative pressure of the whole discharging channel needs to be kept in order to prevent malignant odor generated by sludge or wet sludge from overflowing to the outdoor environment, the waste gas drainage tube 32 is led out from one side of the middle-lower section of the sealing steel tube 31 and is connected into a primary air port A of the boiler, and the vacuum pump 33 is connected into the waste gas drainage tube 32 and is used for generating and maintaining the negative pressure in the sealing canvas cover. The sealing canvas cover is connected with the rubber air bag 35 into a whole from the front section of the discharge passage, the rubber air bag 35 is a ring with a horizontally arranged central shaft, and the size of the ring is suitable for the discharge opening 12 of the sludge truck 1 to be compatible with the ring; in addition, the rubber air bag 35 is connected with an inflator pump 5 and an air release valve 6 which are controlled to adjust the self-filling state, and in order to prevent the malodorous gas in the wet sludge bin from overflowing from the rubber air bag in the non-discharging time period, the rubber air bag is provided with a self-resetting temporary isolating layer close to the inner side of the sealing canvas cover.
Based on the above summary scheme, what needs to be described is: in order to replace the functions of the traditional sludge discharging room and overcome the defects in many aspects, the connecting device is mainly characterized in that the rubber air bag is provided with the negative pressure maintaining part which is similar to the negative pressure maintaining part and the power consumption of which is greatly reduced. In order to be suitable for the sludge vehicle to back up or move forward and enable the discharge opening of the sludge vehicle to freely enter and exit the rubber air bag, the diameter of the rubber air bag needs to be enlarged to a certain degree; moreover, when the sludge box 11 of the sludge vehicle is used for discharging sludge, the controlled inclination is needed (as shown in fig. 1), the discharge opening 12 of the sludge vehicle is completely compatible with the rubber air bag, and the inner size of the rubber air bag is also needed to meet the compatibility of the inclined material box 11. When the discharging channel is opened and sludge is discharged, even if negative pressure exists, the foul gas generated by the sludge is difficult to avoid overflowing due to rolling. Therefore, it is necessary to inflate the air bladder to fully fit the outer wall of the bin and to completely isolate the discharge passage from the environment. And after the discharge is finished, the air-out operation of the rubber air bag is carried out, so that the rubber air bag is in contact with the outer wall of the discharge opening and is relaxed. Therefore, the rubber air bag with controllable inflation degree becomes a main basis for the core component and the function realization of the connecting device for the sludge truck.
In view of further detailed features and optional implementation, the sealed steel pipeline is a coaxial sleeve with adjustable length in a telescopic mode, and the middle section of the sealed steel pipeline is provided with a clamp assembly 311 capable of being unlocked and locked controllably. The length of the sealed steel pipeline can be telescopically adjusted and locked on the premise of ensuring the self sealing of the sealed steel pipeline. The design aims to properly adjust the height of the sealing canvas cover and the rubber air bag relative to the discharge opening according to the heights of different vehicles so as to facilitate accurate and reliable butt joint. The hoop component can be a marble or a bolt and a positioning hole thereof, and can also be a hoop which is sleeved outside and is screwed and fastened, and the implementation-related implementation means is various for the technicians in the field, and the implementation-related implementation means is not taken as the key point of the protection of the application, so the exemplary description is omitted.
The above-described sealing canvas cover is constituted by a plastic sealing canvas 34a and a flexible sealing canvas 34b, wherein the plastic sealing canvas 34a is provided in a flat plate shape for bottom support, and a sufficient load bearing strength is required as a part of a load bearing structure which is in direct contact with the sludge. The flexible sealing canvas 34b is connected with the plastic sealing canvas 34a in a wrapping shape to form a special-shaped steering channel. And as can be seen in the figure, the plastic seal canvas 34a is also provided in a downwardly inclined shape in the sludge flow direction; therefore, the flow and the speed increase during sludge discharging are facilitated.
In the illustrated embodiment, the inflator 5 is connected to one side of the air bladder 35 via a hose 4, and the air release valve 6 is disposed on the other side of the air bladder away from the inflator. Therefore, the air flow for inflation and deflation can be effectively changed in a single direction, and the efficiency of inflation and deflation of the rubber air bag is improved. Here, the medium for inflating and deflating the rubber air bag is mainly outdoor air, so that the risk of pollution or explosion of a high-pressure air source is avoided.
As a preferred embodiment of the temporary blocking layer, a sealing baffle 36 with the top pivoted to the rubber air bag 35 can be used, the sealing baffle 36 is hung in a natural state, the overall breadth of the sealing baffle is larger than the inner contour of the rubber air bag, and the rubber air bag can be completely closed from the inner side. And in the sludge unloading time period, the sludge unloading device is driven by the thrust of the unloading opening to turn inwards and open the unloading channel, and when the unloading is finished and the sludge vehicle drives away, the sludge vehicle is driven by the dead weight to reset and close the unloading channel, and meanwhile, the gas in the inner cavity of the isolation device overflows. The temporary partition layer may be a flexible self-sealing shutter or blind, in addition to a sealing barrier customized from various rigid plates.
In addition to the above mechanical assembly members, the connection device can be configured and connected to various processing units or upper PCs having a control function for saving labor and facilitating operation and use. In particular, sludge treatment stations are usually provided with a master controller located in a control center. Of course, a small machine control unit of the micro-controller can be arranged beside the parking space of the sludge vehicle. And after the connecting device completes the infrastructure, the vacuum pump, the inflator pump and the deflation valve are all connected into the main controller or the microcontroller through signal lines, wherein the microcontroller is integrated with a communication unit for interacting instructions with the mobile terminal. In addition, the sealing baffle is connected with a sensor for detecting the opening and closing states of the discharging channel, and the sensing signal is used as a trigger signal of sludge discharging to be in butt joint interaction with a main controller of a sludge treatment station or a microcontroller arranged beside a sludge vehicle parking space.
Because the connecting device needs fewer electric parts to be controlled in the operation process, only the vacuum pump is controlled to be started to provide negative pressure or to be closed and stopped, the inflator pump is controlled to be started to inflate the rubber air bag to enable the rubber air bag to be inflated or to be closed and stopped, and the deflation valve is controlled to be opened to reduce the pressure of the rubber air bag. It can be seen that the above are all electromechanical control implementations commonly known to those skilled in the art, and are not the focus of the claims of the present application, so that the detailed description is omitted. But from an implementation perspective, may include, but is not limited to, the following.
When the sludge vehicle is a remote main controller, after the sludge vehicle accurately falls, an operator inputs an instruction for starting the unloading operation in a control room, and remotely drives related components to operate according to requirements. And when the remote control is a microcontroller arranged nearby, the driver of the sludge vehicle is an operator for unloading, and the mobile terminal can be in signal connection with the microcontroller and can interact with instructions. When the sludge vehicle is accurately positioned, a driver can operate the mobile phone, operate all functional components, complete the unloading operation according to a preset flow, and interact instructions to reset the connecting device and keep silent after the unloading is completed.
According to the connecting device, from the implementation of an operation period of sludge discharging, after a sludge vehicle conveys sludge, a reversing mode is adopted, the discharging opening of the sludge vehicle is inserted into the rubber air bag, and meanwhile, the thermoplastic sealing baffle is pushed open. At the same time or before, the vacuum pump can be started to form and maintain the negative pressure in the inner cavity of the device. And then operating the material box of the sludge truck to turn backwards by a proper angle (usually 30-60). Then, according to the contact degree of the rubber air bag and the material box, the inflation pump is properly started to inflate, so that the rubber air bag gradually swells and contacts more tightly; the purge valve is now closed. And then opening the discharge port of the sludge truck to start discharging. The sludge falls into the wet sludge bin through the plastic sealing canvas and the sealing steel pipeline. And after the sludge vehicle finishes discharging, closing the discharging opening. On the premise that the inflator pump is closed, the air release valve is properly opened to reduce the pressure of the rubber air bag, so that the sludge vehicle can easily leave the parking space. The sealing baffle is automatically closed along with the driving of the sludge vehicle. Before the sludge vehicle completely drives away and the sealing baffle plate resets to exert the function of isolating the outside, the vacuum pump is kept in an opening state to maintain the negative pressure in the sealing canvas cover, and the overflow of waste gas or foul gas is avoided to the greatest extent.
In summary, the present invention provides a solution and an embodiment of the connecting device, which have the following substantial features and remarkable progressions: the rubber air bag is directly butted with the discharge opening of the sludge truck and depends on controllable sealing measures, so that the sludge truck can directly discharge sludge outdoors conveniently, and a sludge discharge room is avoided; the power consumption and the medicament consumption of the vacuum pump are greatly reduced, energy is saved, and the construction and operation cost is reduced; meanwhile, sealing measures are more concentrated, and the environment pollution can be effectively prevented.
In addition to the above embodiments, the present invention may have other embodiments, and any technical solutions formed by equivalent substitutions or equivalent transformations are within the scope of the present invention as claimed.
