Embodiment 1

[0034] The nano-calcium carbonate production line of the present invention comprises a full-automatic PLC control system and on-site production equipment.

[0035] The structure of the on-site production equipment is as follows figure 1 As shown, it mainly includes trough digester 4, quicklime feeding device, digested water tank 12, first heat exchanger 9, first circular vibrating screen 15, coarse slurry tank, waste water tank 39, secondary coarse slurry tank 20, rotary Liquid separator 23, second circular vibrating screen 24, recovery water tank 32, fine slurry tank 25, fine slurry tank 27 and second heat exchanger 31.

[0036]The trough digester 4 of the present invention is a three-slot digester, the feed end of the first tank of the three-slot digester is respectively connected to the quicklime feeding device and the digestion water pipe, and the discharge end of the third tank is connected to the first circular vibrating screen 15, The waste water discharge end of the t...

Embodiment 2

[0051] Utilize the process that the production line described in embodiment 1 produces nano-calcium carbonate is:

[0052] (1) The screened quicklime is sent to the silo 1, and the quicklime in the silo passes through the electromagnetic vibrating feeder 2, falls on the weighing belt conveyor 3, and is transported to the trough digester 4; the production water flows along the water supply pipe The second branch 13 of the road enters the digested water tank 12 after the second heat exchanger 31 initially heats up. The digested water in the digested water tank 12 is pumped by the digested water pump 11 into the digested water pipeline 8, the digested water in the digested water pipeline 8 exchanges heat with the steam in the steam pipeline 10 in the first heat exchanger 9, and enters the In the trough digester 4, quicklime in the trough digester 4 reacts with digested water to obtain a coarse slurry of calcium hydroxide.

[0053] (2) The coarse slurry enters the coarse slurry t...

Abstract

The invention discloses a nanometer calcium carbonate digestion production line. The nanometer calcium carbonate digestion production line comprises a fully-automatic PLC system and an onsite production device; the production device mainly comprises a tank digester, a digestion water tank, a first heat exchanger, a first circular vibrating screen, a coarse slurry tank, a wastewater tank, a secondary coarse slurry tank, a hydrocyclone separator, a second circular vibrating screen, a recovered water tank, a fine slurry tank, a refined slurry tank and a second heat exchanger, and the fully-automatic PLC system includes a computer, a distributed I / O slave station, and a control box, a touch screen and a fault alarm which are arranged on site; and the online concentration detector, the temperature sensor, the dust sensor, the liquid level sensor and the pressure sensor of the production device are connected and communicated with the PLC control system. The control system is controlled through 485-modbus in PLC communication, so the operation can be easily controlled; and the whole digestion system can completely realize the fully-automatic mechanized production of nanometer calcium carbonate, realizes onsite unmanned operation, and completely realizes the mechanical and intelligent production from digestion to dust removal, slag removal and slurry refining.

Description

technical field [0001] The invention relates to calcium carbonate production equipment, in particular to a PLC-controlled full-automatic nano calcium carbonate digestion production line. Background technique [0002] Calcium carbonate is an important inorganic chemical product and one of the most widely used inorganic fillers. Nano-calcium carbonate is suitable for different fields due to its different particle sizes, and has a wide range of applications in industries such as rubber, plastics, paper, coatings, and inks. The existing nano-calcium carbonate production line is relatively low in automation, the production equipment is unreasonably configured, and the front and rear controls in the production process cannot be coordinated and unified, which affects the consistency of the produced nano-calcium carbonate particles. Contents of the invention [0003] The purpose of the present invention is to provide a kind of automatic nano-calcium carbonate production line, the...
