Description
Technical Field
The utility model relates to a chlorinated polyethylene preparation technical field especially relates to a vacuum pump jar combination.
Background
Chlorinated polyethylene is a high molecular material prepared from high-density polyethylene through chlorination substitution reaction, and is mainly used as a resin impact modifier and synthetic rubber. At present, the product is mainly produced in our country. During the reaction and separation processes, a large amount of vacuum pump suction is required. At present, water ring type or jet-suction type vacuum pumps are mostly adopted as vacuum sources.
The defects and shortcomings of the prior art are as follows: most of the existing vacuum forming methods adopt a water-ring type or jet-suction type vacuum pump which takes process water as power liquid, a large amount of fresh water needs to be continuously consumed, and in the production of chlorinated polyethylene, the extracted gas is mainly hydrogen chloride which is very soluble in water. After the hydrogen chloride is dissolved in the power liquid circulating water, the hydrogen chloride becomes waste diluted acid water, and the key point is that the water is difficult to recycle and can only enter a subsequent wastewater treatment process and be treated by a sewage treatment plant. Not only causes the waste of water resources, but also causes the pressure of environment-friendly wastewater treatment.
Disclosure of Invention
The utility model aims at solving the prior art and providing a vacuum pump tank combination for the vacuum formation of chlorinated polyethylene. The vacuum forming mode uses the original hydrochloric acid tank of the device, and uses hydrochloric acid pumped by a circulating pump of the hydrochloric acid tank as power of a jet vacuum pump to form vacuum. Therefore, the hydrogen chloride gas pumped in the vacuum pumping process is dissolved in the hydrochloric acid, the concentration of the hydrochloric acid is increased, byproducts are recovered, and the effect of saving fresh water is achieved.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a vacuum pump canister combination comprising: hydrochloric acid storage tank, jet pump and hydrochloric acid circulating pump, wherein: hydrochloric acid tank inlet at the top of the hydrochloric acid storage tank is connected with an injection pump, the injection pump is connected with a hydrochloric acid circulating pump, the hydrochloric acid circulating pump is connected with the bottom of the hydrochloric acid storage tank, and the injection pump is connected with a vacuum pipeline for providing vacuum.
Further preferably, the top of the hydrochloric acid storage tank is provided with an exhaust port.
Further preferably, the hydrochloric acid storage tank is made of glass fiber reinforced plastic.
Further preferably, the injection pump is made of PP material.
Further preferably, the hydrochloric acid circulating pump adopts a fluoroplastic alloy pump.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model provides a pair of vacuum pump jar combination in production system, utilizes hydrochloric acid solution of hydrochloric acid storage tank, reduces the source of a continuous use fresh water to reach the purpose of water conservation.
2. The utility model provides a pair of vacuum pump jar combination reduces the production that contains acid waste water, reduces the waste water treatment expense, reaches environmental protection and emission reduction's purpose.
3. The utility model provides a pair of vacuum pump jar combination has reduced the equipment that sets up vacuum pump waste water alone and collect and carry the waste water station, practices thrift investment and space.
Drawings
Fig. 1 is a front view of the present invention;
in the figure: 1 is an exhaust port; 2 is a jet pump; 3 is a hydrochloric acid inlet; 4 is hydrochloric acid solution; 5 is a hydrochloric acid circulating pump; 6 is a vacuum pipeline; and 7 is a hydrochloric acid storage tank.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1, a vacuum pump canister combination includes: hydrochloric acid storage tank 7, jet pump 2 and hydrochloric acid circulating pump 5, wherein: hydrochloric acid tank inlet 3 at the top of hydrochloric acid storage tank 7 is connected with jet pump 2, jet pump 2 is connected with hydrochloric acid circulating pump 5, hydrochloric acid circulating pump 5 is connected with the bottom of hydrochloric acid storage tank 7, jet pump 2 is connected with vacuum pipeline 6 that provides the vacuum.
And the top of the hydrochloric acid storage tank 7 is provided with an exhaust port 1.
The hydrochloric acid storage tank 7 is made of glass fiber reinforced plastic.
The injection pump 2 is made of PP materials.
The hydrochloric acid circulating pump 5 adopts a fluoroplastic alloy pump.
In this embodiment, when in use, the injection and suction pump with the circulation amount corresponding to the specification is determined according to the storage amount of the hydrochloric acid storage tank. Since the solution storage amount is too small, the circulation amount is too large, and the solution temperature is easily raised too much. The vacuum pump tank combination is made of the following materials: the circulating pump adopts fluoroplastic alloy pump, the vacuum injection pump adopts PP material, the hydrochloric acid storage tank adopts glass steel material, pipeline valve etc. adopt PP material. When the device is used, the hydrochloric acid circulating pump extracts the hydrochloric acid solution from a liquid outlet at the bottom of the hydrochloric acid storage tank, the hydrochloric acid solution passes through the jet-suction pump and enters the tank from the top of the hydrochloric acid tank, and the functions and effects of forming vacuum and absorbing hydrogen chloride waste gas are achieved simultaneously in the circulating process of the hydrochloric acid solution.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
