Description

Technical Field

[0001] The utility model relates to the technical field of pulverizing equipment, in particular to a black dye intermediate pulverizing and feeding device. Background Art

[0002] In the preparation process of black dye intermediates, the crushing pretreatment of the raw material solid preparation 6-nitro-1-diazo-2-hydroxy-4-naphthalenesulfonic acid is the first step of the reaction. The uniformity of material mixing and the uniformity of particle content will directly affect the particle size distribution of the raw materials, product quality, and the conversion rate of the reaction. Therefore, the particle size control of the raw materials is generally listed as one of the key process parameters.

[0003] Traditional crushing and feeding devices usually use mechanical grinders in conjunction with manual and semi-automatic feeding systems for crushing and feeding. During the crushing and feeding process, the labor intensity is high, which affects the processing efficiency. At the same time, the crushing is uneven, which affects the use effect of the raw materials. The control of the feeding amount is not precise enough, which affects the stability of product quality. At the same time, a large amount of dust is easily generated during the crushing process, which pollutes the environment and endangers the health of operators.

[0004] Therefore, a black dye intermediate pulverizing and feeding device is proposed. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. By setting up a quantitative conveying component, when the PLC controller controls the electric telescopic rod to retract, the electric telescopic rod can drive the piston to slide upward along the injection groove. At this time, the pressure in the injection groove becomes smaller, thereby generating suction in the injection groove, causing the solution in the mixing barrel to squeeze the one-way valve in the feed pipe and enter the injection groove from the feed pipe. By controlling the contraction length of the electric telescopic rod, the suction amount of the solution in the quantitative cylinder can be controlled. When the electric telescopic rod is extended, the electric telescopic rod can drive the piston to squeeze the solution in the injection groove. At this time, the solution can squeeze the one-way valve in the discharge pipe into the storage barrel. Then, the quantitatively extracted solution can be introduced into the next processing step through the guide pump, which can achieve accurate quantitative injection and ensure the stability of product quality.

[0016] 2. By setting up a crushing component, when the PLC controller drives the first motor to work, the first motor can drive the rotating shaft to rotate at high speed in the crushing barrel, so that the cutting blade on the outside of the rotating shaft can crush the solid raw materials entering the crushing barrel through the feeding pipe, and the raw material particles that meet the standards can pass through the filter net into the conduit, and are further gradually sent into the mixing barrel through the solenoid valve on the conduit. The raw materials with larger particles can continue to be crushed by the cutting blades until they meet the standards, and the crushing efficiency can be improved by crushing with multiple cutting blades. During the crushing process, the fan can extract the dust generated during the crushing process from the crushing barrel, and further collect it through a dust bag, which can avoid dust pollution to the surrounding environment and protect the health of the staff. It is automatically controlled by the PLC controller, which can reduce manual operation, liberate labor, and improve processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] See also Figure 4 , corresponding one-way valves 24 are respectively provided on the feed pipe 3 and the discharge pipe 6.

[0029] In this embodiment, during use, when the PLC controller 2 controls the electric telescopic rod 8 to retract, the electric telescopic rod 8 can drive the piston 19 to slide upward along the injection groove 20. At this time, the pressure in the injection groove 20 becomes smaller, thereby generating suction in the injection groove 20, causing the solution in the mixing barrel 1 to squeeze the one-way valve 24 in the feed pipe 3 and enter the injection groove 20 from the feed pipe 3. By controlling the contraction length of the electric telescopic rod 8, the suction amount of the solution in the metering cylinder 7 can be controlled. When the electric telescopic rod 8 is extended, the electric telescopic rod 8 can drive the piston 19 to squeeze the solution in the injection groove 20. At this time, the solution can squeeze the one-way valve 24 in the discharge pipe 6 into the storage barrel 4. Then, the quantitatively extracted solution can be introduced into the next processing step through the guide pump 5, so that accurate quantitative injection can be achieved and the stability of product quality can be guaranteed.

[0030] Embodiment 2:

[0031] See also Figures 1 to 3The utility model provides a technical solution: a black dye intermediate crushing and feeding device, which also includes: a crushing component arranged in a crushing barrel 10, the crushing component includes a first motor 12 fixedly installed on the top of the crushing barrel 10, and the output end of the first motor 12 extends to the crushing barrel 10 and is fixedly connected to a rotating shaft 23, and a plurality of cutting blades 16 are evenly and fixedly installed on the rotating shaft 23.

[0032] See also Figure 2 A filter screen 22 is fixedly installed at the bottom end of the crushing barrel 10, and a conduit 15 is connected to the bottom end of the crushing barrel 10.

[0034] In this embodiment, during use, when the PLC controller 2 drives the first motor 12 to work, the first motor 12 can drive the rotating shaft 23 to rotate at high speed in the crushing barrel 10, so that the cutting blade 16 on the outside of the rotating shaft 23 can crush the solid raw materials entering the crushing barrel 10 through the feeding pipe 13, and the raw material particles that meet the standards can pass through the filter screen 22 into the conduit 15, and are further gradually sent into the mixing barrel 1 through the solenoid valve 17 on the conduit 15. The raw materials with larger particles can continue to be crushed by the cutting blade 16 until they meet the standards, and the crushing efficiency can be improved by crushing with multiple cutting blades 16. During the crushing process, the fan 11 can extract the dust generated during the crushing process from the crushing barrel 10, and further collect it through a dust collecting bag, so as to avoid the dust from polluting the surrounding environment and protect the health of the staff.

[0035] Working principle: First, put the solid raw material into the crushing barrel 10, and then drive the first motor 12 to work through the PLC controller 2. At this time, the first motor 12 can drive the rotating shaft 23 to rotate at high speed in the crushing barrel 10, so that the cutting blade 16 on the outside of the rotating shaft 23 can crush the solid raw material entering the crushing barrel 10 through the feeding pipe 13. The raw material particles that meet the standards can pass through the filter screen 22 and enter the conduit 15, and are further gradually sent into the mixing barrel 1 through the solenoid valve 17 on the conduit 15. The raw materials with larger particles can continue to be crushed by the cutting blade 16 until they meet the standards. Crushing by multiple cutting blades 16 can improve the crushing efficiency. During the crushing process, the fan 11 can extract the dust generated during the crushing process from the crushing barrel 10, and further collect it through the dust bag, which can avoid dust pollution to the surrounding environment and protect the health of the staff. When the raw materials that meet the standards enter the mixing barrel 1 , an appropriate amount of water is injected into the mixing barrel 1 through the flow valve 21 and the water injection pipe 9, and then the stirring roller 18 is driven by the second motor 14 to mix and form a solution.
