Detailed Description

The present invention will be further explained below.

Example (b):

as shown in figures 1 and 2, the paint stirring tank with the material overturning function comprises a tank body 1 and a stirring piece, wherein the stirring piece comprises a motor 2, a stirring shaft 3 and stirring blades 4, the motor 2 is positioned at the top of the tank body 1, the output end of the motor 2 is in transmission connection with the stirring shaft 3, the stirring shaft 3 extends into the tank body 1, and the stirring blades 4 are arranged on the stirring shaft 3.

The main feed inlet 11 is seted up at jar body 1 top, and main feed inlet 11 department is provided with the closed door 12 that is used for sealing main feed inlet 11. The main charge door 11 mainly used is the interpolation of a large amount of materials for the first time, and the size of main charge door 11 does not have more obvious difference with the size of charge door on the conventional agitator tank, can accomplish the interpolation of a large amount of disposable materials smoothly, uses the closed door 12 to seal main charge door 11 after the interpolation is accomplished, and harmful gas that can effectually avoid producing when the stirring overflows from main charge door 11.

In the stirring process, need add some auxiliaries or partial batching, the volume of adding is obviously less than in the addition amount for the first time relatively, if open closing door 12 this moment, a large amount of harmful gas that produces in the stirring process just can scurry out from main charge door 11, endangers operating personnel's health, if adopt the less body of diameter to feed in raw material this moment, the diameter of body can be sheltered from basically to the material when feeding in raw material, just can effectual reduction harmful gas's escape. Therefore, in this application, jar body 1 top still communicates and is provided with the vice filling tube 13 of metal system for carry out the interpolation of material in the stirring process. In order to avoid harmful gas from escaping from the auxiliary feeding pipe 13 when the material is not added, a material valve 131 is arranged on the auxiliary feeding pipe 13 to block the auxiliary feeding pipe 13 when the material is not added.

In order to facilitate the charging of an operator, the auxiliary charging pipe 13 is inserted with the charging hopper 7, when charging, the material is placed in the charging hopper 7, and then the charging can be performed by opening the material valve 131. The connected mode of loading hopper 7 and auxiliary feed pipe 13 is for pegging graft for the suitable loading hopper 7 is selected to the volume of the material that operating personnel can add according to actual need, can make different kinds of materials pair the loading hopper 7 that corresponds simultaneously, can make the loading hopper 7 that the use of solid additive and liquid additive is different for example. When the loading hopper 7 is replaced, the loading hopper 7 is directly pulled out, so that the operation difficulty of an operator is reduced. In order to facilitate the inserting operation of an operator, the mouth of the auxiliary feeding pipe 13 is turned outwards to form a curled edge, so that the inserting end of the feeding hopper 7 is guided. The outer side wall of the charging hopper 7 is provided with a rubber ring 71 which is used for abutting against the mouth of the auxiliary charging pipe 13, so that harmful gas is prevented from escaping from a gap between the charging hopper 7 and the auxiliary charging pipe 13, and the escaping point of the harmful gas is reduced as much as possible. To the liquid material of jar internal interpolation usually organic compound, when accomplishing the material and adding back change loading hopper 7, the bottom of loading hopper 7 can remain partial organic compound liquid, this organic compound probably drips the tube mouth department at vice filling tube 13, if rubber circle 71 is located the tube mouth department of vice filling tube 13 then can contact with organic compound, very big influence rubber circle 71's life, it is also difficult to wipe cleanly because of the liquid that rubber circle 71 material problem drips on, consequently rubber circle 71 sets up on loading hopper 7 in this application, it can to adopt earlier when there is the spot in vice filling tube 13 mouth of pipe to wipe clean back installation rag 7 again.

Although the auxiliary feeding pipe 13 is arranged to reduce the feeding caliber and reduce the escape of harmful gas, part of harmful gas still escapes in the feeding process, in order to reduce the escape of harmful gas as much as possible, the top of the tank body 1 is also communicated with an exhaust pipe 5, the exhaust pipe 5 is provided with an exhaust fan 51, and the other end of the exhaust pipe 5 is communicated with a gas filtering device 6. Start air exhauster 51 when reinforced to open material valve 131, the gas in the jar body 1 is taken away by air exhauster 51 this moment, makes jar body 1 internal negative pressure state that appears, and external gas and the material in the loading hopper 7 can get into from vice filling tube 13 under the atmospheric pressure effect, has effectively reduced the escape of harmful gas from vice filling tube 13 in the charging process, has still assisted the interpolation of material simultaneously. The gas extracted by the exhaust fan 51 contains harmful gases, and is finally sent to the gas filtering device 6 to be purified, and the purified gas is finally discharged.

The whole charging process reduces the escape problem of harmful gas as much as possible, reduces the environmental pollution and improves the safety factor of operators.

As shown in fig. 1 and 3, when the material is stirred in the tank body 1, in order to uniformly select the stirring blades 4 with better stirring effect in the application as square blades, the square blades are uniformly distributed along the length direction of the stirring shaft 3. And because the paint density is higher and is more difficult during stirring, in order to reduce the overlarge stress at the connecting point of the square blade and the stirring shaft 3, the plurality of direction blades are all obliquely arranged, the oblique direction is opposite to the moving direction, the paint can be turned over under the guiding action of the square blade during stirring, and the resistance borne by the square blade is reduced. In order to avoid being located the paint deposit of jar body 1 bottom, the stirring is inhomogeneous, and the square blade that is close to jar body 1 bottom in stirring vane 4 is 5 ~ 15mm with the distance of jar internal diapire, guarantees also can be stirred evenly the paint of jar body 1 bottom, simultaneously because of square blade slope, the paint that the square blade can be located jar body 1 bottom is shoveled and is stirred when the (mixing) shaft 3 rotates, reaches better stirring effect.

The working process is as follows:

an operator installs the charging hopper 7 at the position of the auxiliary charging pipe 13, the material valve 131 on the auxiliary charging pipe 13 is in a closed state at the moment, and then the operator opens the closing door 12 to add materials into the main charging opening 11 and closes the closing door 12 after the addition is completed. When adding materials in the stirring process, an operator places the materials in the charging hopper 7, then opens the material valve 131 and opens the exhaust fan 51, and after the materials are added, the material valve 131 and the exhaust fan 51 are closed simultaneously. The whole charging process reduces the leakage of harmful gas as much as possible and reduces the pollution to the environment.

The principles and embodiments of the present invention have been described herein using specific examples, which are provided only to help understand the method and the core concept of the present invention; while the utility model has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
