The utility model relates to a double-barrel switching device for a waste solvent, which is used for receiving the waste solvent and switching one barrel to the other barrel after the other barrel is full, in particular to a double-component waste solvent recovery system for a dry spraying room.
Background
Paint is cleaned by solvent when changing color, and a large amount of waste solvent is generated. The waste solvent is conveyed to a storage room from a spray room through a pipeline for unified recovery treatment; the traditional waste solvent recovery method is to recover the waste solvent into a stainless steel cylinder firstly, and then pour the waste solvent into a raw material barrel through a diaphragm pump after the stainless steel cylinder is full, and the waste solvent is conveyed away and treated by a paint manufacturer in a unified way. Stainless steel drums are typically expensive and require a dosing pump to complete the final recovery. The stainless steel barrel generally uses an electronic liquid level meter or a floating ball type pneumatic liquid level meter, and the electronic liquid level meter is easy to generate faults due to the interference of the environment or media because some residual liquid is recovered to be double-component suspension. The pneumatic floating ball liquid level meter has a complex structure, and the floating ball is easy to crust on the surface to cause the blocking of the floating ball bonding activity to generate faults.
The above prior art has the following disadvantages: 1. the process of rewinding is complicated; 2. the cost is high; 3. the electronic level gauge is unsafe to use.
In conclusion, the utility model designs a double-component waste solvent recovery system of a dry spraying room.

Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.
Referring to fig. 1-2, the following technical solutions are adopted in the present embodiment: a dry-type spray room two-component waste solvent recovery system comprises a pneumatic control cabinet 1, a first waste solvent recovery barrel A, a second waste solvent recovery barrel B, A, a barrel pneumatic angle valve 2, a barrel pneumatic angle valve B3, a main pipeline 4, a diversion pipe 5, a hose 6, a recovery pipe 7 and a recovery pipe limiting block 8, wherein the main pipeline 4 is connected with the hose 6 through two diversion pipes 5, the tail end of the hose 6 is connected with the recovery pipe 7, the recovery pipe 7 is respectively fixed on the first waste solvent recovery barrel A and the second waste solvent recovery barrel B through the recovery pipe limiting block 8, the diversion pipe 5 is respectively inserted with the barrel pneumatic angle valve A2 and the barrel pneumatic angle valve B3, the inner sides of the barrel pneumatic angle valves A2 and the barrel pneumatic angle valve B3 are provided with a manual valve 9, the diversion pipes 5 at the installation positions of the barrel pneumatic angle valves A2 and the barrel pneumatic angle valve B3 are also provided with pneumatic sensors, the barrel pneumatic angle valve A2, the barrel pneumatic angle valve B are connected with a pneumatic angle valve B, and a pneumatic angle valve B valve 2, The pneumatic angle valve 3 of the barrel B and the pneumatic sensor are both connected with the pneumatic control cabinet 1.
It is worth noting that the air pressure regulating filter 10 is arranged on the side of the air control cabinet 1.
It is worth noting that the pneumatic sensor adopts a pneumatic blowing micro-sensor, the sensitivity is 0.1bar, namely the pressure change is 0.1bar, and the triggering can be realized; for bucket full detection.
In addition, a tuning fork switch can be added on the small openings of the first waste solvent recovery barrel A and the second waste solvent recovery barrel B for standby.
The system of the embodiment is divided into a fluid passage and a pneumatic element control passage; the fluid passage consists of various pipes, pipe fittings and a manual automatic control valve and is arranged outside; the pneumatic control channel comprises various pneumatic control elements and an air source processing element and is arranged in the pneumatic control cabinet.
The pneumatic control cabinet of the embodiment is selected by two manual and automatic modes in the waste solvent recovery process: in the automatic mode, when the liquid level of the first waste solvent recovery barrel A is high, the recovery pneumatic valve (the barrel A pneumatic angle valve 2) of the first waste solvent recovery barrel A is closed, meanwhile, the recovery valve of the barrel B is opened, and the waste solvent is recovered into the barrel B; on the contrary, when the waste solvent barrel B is at a high liquid level, the recovery pneumatic valve of the barrel B is closed, meanwhile, the pneumatic angle valve 2 of the barrel A of the first waste solvent recovery barrel A is opened, and the waste solvent is recovered into the first waste solvent recovery barrel A; in the manual mode, an operator can control the recovery valve above each barrel through a manual button switch of the pneumatic control cabinet. In the manual mode, the recovery valve is manually forced to act and is not limited by the liquid level.
Since the gas requires a stable pressure, slight fluctuations may lead to false sensor alarms, and it is therefore necessary to ensure that the gas source process is absolutely reliable. The compressed air filtering precision is not more than 1 mu m, all air path supplies need step by step pressure regulation to ensure the pressure stability, and the pressure regulation pressure needs to be confirmed according to specific debugging because the length and the pipe diameter of the air pipe are different.
The automatic valve of the fluid passage needs to be reliable, and the valve which is resistant to the organic solvent needs to be integrally used for controlling the on-off of the passage because the conveying medium is the organic solvent; if double protection is needed, a tuning fork switch can be added on a small opening of the raw material barrel for standby.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
