Abstract
The utility model discloses a sodium hydride filter pressing hydraulic device, which comprises a filter press and a hydraulic station communicated with the filter press. A pressure valve is arranged between the filter press and the hydraulic station, and the hydraulic device is provided with a relief safety protection device including a manual hydraulic device communicated with the filter press and mutually connected in parallel with the hydraulic station. The hydraulic device greatly reduces safety risk in case of failure of a pressure system, and is simple in operation and high in reliability.
Description
Technical field
The utility model relates to the chemical industry equipment field, relates in particular to a kind of sodium hydride pressing filtering liquid pressure device.
Background technology
Sodium hydride is a kind of pungent, and chemical reactivity is very high, can spontaneous combustion in humid air, and be heated or contact and promptly emit heat and hydrogen with moisture, acids, cause burning and explode, chemical equation is: NaH+H
2O=NaOH+H
2Kickback can take place in sodium hydride and oxidant in addition, causes burning or blast.Meet moisture and moisture and generate hydroxide, corrosivity is very strong.Sodium hydride is used as condensing agent, reducing agent, alkylating reagent, catalyst and Ke Laixun reagent etc. in organic synthesis; Also can be used for medicine, spices, agricultural chemicals, fuel, brightening agent and macromolecule industry etc.Press filtration operation in the preparation process of sodium hydride; the general chamber-type press filter that uses carries out press filtration; run into that pressure system breaks down or power outage suddenly through regular meeting in the actual production; this moment, chamber-type press filter was because of pressure release; material in the filter press contacts with air, is easy to take place security incidents such as burning or blast.
Summary of the invention
Technical problem to be solved in the utility model is: the deficiency at prior art exists provides a kind of sodium hydride pressing filtering liquid pressure device that has the pressure release safety guard.
For solving the problems of the technologies described above, the technical solution of the utility model is:
Sodium hydride pressing filtering liquid pressure device; comprise filter press; with the Hydraulic Station that is communicated with described filter press; be provided with pressure valve between described filter press and the described Hydraulic Station; described hydraulic means is provided with the pressure release safety guard; described pressure release safety guard comprises with described filter press and being communicated with and the manual hydraulic device parallel with one another with described Hydraulic Station that described manual hydraulic device is super-pressure hand-hydraulic station.
As a kind of improvement, described pressure release safety guard also comprises the standby pressure valve that is arranged between described manual hydraulic device and the described filter press.
As further improvement, be provided with pressure display table between described filter press and Hydraulic Station parallel with one another and the manual hydraulic device.
Described filter press is a chamber-type press filter.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
1, pressing filtering liquid pressure device of the present utility model is provided with the pressure release safety guard; holding back that pressure system breaks down or during burst accident such as power failure; can use manual hydraulic device to give the chamber-type press filter voltage supply, avoid sodium hydride to contact, security incident takes place with air.
2, the utility model is provided with pressure display table between filter press and Hydraulic Station parallel with one another and manual hydraulic device, in pressure maintaining period, descends if pressure shows, utilizes the manual hydraulic device ftercompction at any time.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment.
Among the figure, 1. chamber-type press filter; 2. Hydraulic Station; 3. pressure valve; 4. pressure release safety guard; 41. manual hydraulic device; 42. standby pressure valve; 5. pressure display table.
The specific embodiment
As shown in drawings; sodium hydride pressing filtering liquid pressure device; comprise chamber-type press filter 1; with the Hydraulic Station 2 that is communicated with described chamber-type press filter 1; be provided with pressure valve 3 between described chamber-type press filter 1 and the described Hydraulic Station 2; described hydraulic means is provided with pressure release safety guard 4; described pressure release safety guard 4 comprises with described chamber-type press filter 1 and being communicated with; and the manual hydraulic device 41 parallel with one another with described Hydraulic Station 2, be provided with standby pressure valve 42 between described manual hydraulic device 41 and the described chamber-type press filter 1.Be provided with pressure display table 5 between described chamber-type press filter 1 and Hydraulic Station 2 parallel with one another and the manual hydraulic device 41.
When the utility model uses, in the pressure-filtering process of sodium hydride, break down or burst accident such as power failure as pressure system, when Hydraulic Station 2 can not normal supply chamber-type press filter 1 pressure, in time closing presure valve 3 was opened standby pressure valve 42, use manual hydraulic device 41 to give chamber-type press filter 1 voltage supply, prevent that the sodium hydride in the chamber-type press filter 1 from contacting with air, when pressure display table 5 shows that pressure reaches requirement, stop pressurization and close standby pressure valve 42.Do not get rid of in the pressure maintaining period in fault,, open standby pressure valve 42 and use manual hydraulic device 41 to continue pressurization if pressure descends.Fault is got rid of pressure system normally during voltage supply, opens pressure valve 3, pressure is provided for chamber-type press filter 1 by Hydraulic Station 2, the maintenance ordinary production.
