Abstract

The utility model discloses a device for controlling the quantitative car loading of hazardous liquid chemicals, which comprises a delivery pump, a relay and an integrating instrument, wherein, a transmission pipeline of the delivery pump is connected with a container and a tank car for containing the hazardous liquid chemicals, and the delivery pump is provided with a flowmeter; a normally opened contact of the relay is electrically connected with the power supply of the delivery pump for on-off control of the delivery pump; and the output end of the flowmeter is electrically connected with the integrating instrument. By means of the electromagnetic flow-meter and the flow rate integrating instrument, the utility model achieves the purpose of automatically controlling the loading volume of the hazardous chemicals, thereby ensuring that car loading measurement of the hazardous chemicals is performed in a timely, accurate and safe manner, and improving work quality and efficiency.

Description

A kind of liquid hazardous chemicals quantifying and loading control setup
(1) technical field
The utility model relates to the device of controlling quantifying and loading, especially a kind of liquid hazardous chemicals quantifying and loading control setup.
(2) background technology
The liquid hazardous chemicals entrucking of more known chemical enterprises generally all is after squeezing into tank car by feedway, to weigh to determine entrucking quantity that said method has the following disadvantages:
In case quantity transfinite carry tonnage or entrucking quantity not enough, the unloading or install the quantity of shortcoming again additional of all needing to move backward, thus bring unnecessary trouble and harm;
2. being difficult to the accurate quantifying and loading of realization controls the size;
3. if operating personal control is untimely, also cause the car that overflows easily, lead to the safety and environmental protection responsible accident.
(3) summary of the invention
The technical problems to be solved in the utility model has provided a kind of liquid hazardous chemicals quantifying and loading control setup, can realize quantifying and loading, stop the function of transmission pump automatically.
In order to solve the problems of the technologies described above, the utility model is realized by following measure: a kind of liquid hazardous chemicals quantifying and loading control setup comprises transmission pump, relay and integrating instrument; The delivery duct of this transmission pump connects and is used for the container and the tank car of carrying liquid dangerous chemical, and is provided with flow counter; The normally opened contact of relay is electrically connected the keying that is used to control transmission pump with the transmission pump power supply; Described flow counter mouth and integrating instrument are by being electrically connected.
The beneficial effects of the utility model:
By electromagnetic flowmeter survey, flow integrator integrating, accumulative total, automatic guidance loads the purpose of dangerous chemical quantity, can guarantee that dangerous chemical entrucking metering is timely, accurate, safety, has improved workmanship and efficient.
(4) description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
1 container among the figure, 2 transmission pumps, 3 flow counter, 4 integrating instruments, 5 relays, 6 reset buttons, 7 tank cars.
(5) specific embodiment
A kind of liquid hazardous chemicals quantifying and loading control setup as shown in Figure 1 comprises transmission pump 2, relay and integrating instrument 4; The delivery duct of this transmission pump 2 connects the container 1 and tank car 7 that is used for the carrying liquid dangerous chemical, and is provided with flow counter 3; The normally opened contact of relay 5 is electrically connected the keying that is used to control transmission pump 2 with transmission pump 2 power supplys; Described flow counter 3 mouths and integrating instrument 4 are by being electrically connected.
During manufacturing integrating instrument 4 and relay 5 can be processed into a control box and reset button 6 is set.
Working process of the present utility model is as follows: check system connects intact guaranteeing during normal can dangerous chemical, start transmission pump 2, dangerous chemical in the container 1 flows into tank car 7 by flow counter 3, flow counter 3 is measured simultaneously, form signal and be sent to integrating instrument 4, integrating instrument 4 adds up, calculates, compares with the number of car loadings value of setting, when integrating instrument 4 accumulation numerical value reach setting numerical value, 5 actions of integrating instrument 4 control relays, make transmission pump 2 outages, realize timely automatic guidance quantifying and loading.
