Description

Technical Field

[0001] The utility model relates to the technical field of chemical engineering, in particular to an integrated feeding machine and a feeding system. Background Art

[0002] Vehicle urea is a necessary product for heavy-duty diesel vehicles to meet emission standards; vehicle urea refers to an aqueous urea solution with a urea concentration of 32.5% and a solvent of ultrapure water, and the raw materials are special raw materials for vehicle urea and ultrapure water. Domestic vehicle urea is mainly purified from industrial urea. Its main process is that at a temperature of 70 - 75°C, urea hydrolyzes in the aqueous solution; when the temperature is below 30°C, urea recrystallizes from the aqueous solution again; each time of hydrolysis and crystallization, its purity will be greatly improved. Generally, by hydrolyzing and crystallizing industrial first-grade urea once, the vehicle urea standard requirements can be met, and its output ratio is 1.5:1; however, the existing vehicle urea mixing and fusing processes are relatively independent, and each device also operates relatively independently, resulting in a large occupation area of the entire production line, and mainly relying on manual operation of the devices respectively, with a high risk of misoperation.

[0021] The following further explains the technical solutions of the present utility model in combination with the attached Figures 1-5 ,...

[0022] Example 1

[0023] As Figures 1-5 shown, an integrated loading machine includes an equipment frame 1, and a mixing storage tank 2 is arranged inside the equipment frame 1. In this embodiment, a stainless steel mixing pump is selected for the mixing storage tank 2.

[0024] Specifically, as Figure 1 shown, a pressurized water supply mechanism and a crushing mechanism are respectively integrated on one side of the mixing storage tank 2 and on the equipment frame 1, so as to pressurize and send ultrapure water into the mixing storage tank 2 through the pressurized water supply mechanism for mixing with urea particles, and to extract the mixed liquid from the mixing storage tank through the crushing mechanism and crush the urea particles contained in the mixed liquid. That is to say, a pressurized water supply mechanism and a crushing mechanism are also integrated on the equipment frame. After pressurizing the ultrapure water by the pressurized water supply mechanism, it is input into the mixing storage tank, and the urea particles in the mixing storage tank are fully mixed. Subsequently, the crushing mechanism extracts the urea mixed liquid from the mixing storage tank and sends it into the blending tank.

[0025] In some embodiments, as Figure 1 and Figure 5 shown, a control cabinet 3 is integrated inside the equipment frame 1, and the control cabinet 3 is electrically connected to the pressurized water supply mechanism and the crushing mechanism respectively, so as to respectively control the on-off states of the pressurized water supply mechanism and the crushing mechanism. That is to say, a control cabinet is integrated inside the equipment frame, and the control cabinet can be used to control the start and operation of the pressurized water supply mechanism and the crushing mechanism.

[0026] In some embodiments, as Figure 1 and Figure 5 shown, the cross-sectional shape of the mixing storage tank 2 is conical, so as to enable the pressurized ultrapure water introduced to flow along the inner wall of the conical mixing storage tank to form a vortex, thereby driving the urea particles in the mixing storage tank to rotate at a high speed and be fully mixed. That is to say, the mixing storage tank is designed in a conical shape. After the pressurized water supply mechanism pressurizes the ultrapure water and inputs it into the mixing tank, the high-pressure ultrapure water can form a strong vortex along the designed taper after entering the tank, thereby driving the urea particles poured into the mixing tank to rotate at a high speed and be fully mixed.

[0027] Specifically, as Figure 1 and Figure 4 shown, the pressurized water supply mechanism includes a liquid inlet high-pressure pump 4, and the water outlet of the liquid inlet high-pressure pump 4 is connected to the upper part of the mixing storage tank 2 through a connecting pipe; a first solenoid valve in the power supply circuit of the liquid inlet high-pressure pump 4 is electrically connected to the control cabinet 3. That is to say, by pressing the switch button of the control cabinet, the power supply circuit of the liquid inlet high-pressure pump is controlled to be closed and energized. After the liquid inlet high-pressure pump is energized and started, it pressurizes the ultrapure water and inputs it into the mixing storage tank, and the high-pressure ultrapure water flows into the mixing storage tank from the upper part along the taper of the mixing storage tank.

[0028] Specifically, as Figure 1 and Figure 4 shown, the crushing mechanism includes a high-pressure crushing pump 5, and the water inlet of the high-pressure crushing pump 5 is connected to the bottom of the mixing storage tank 2 through a liquid inlet pipe; a second solenoid valve in the power supply circuit of the high-pressure crushing pump 5 is electrically connected to the control cabinet 3. That is to say, the starting process of the high-pressure crushing pump is the same as that of the control liquid inlet high-pressure pump, that is, by pressing the switch button on the control cabinet, the high-pressure crushing pump is controlled to be powered on and started. The high-pressure crushing pump extracts the urea mixture from the mixing storage tank. After the mixture enters the crushing pump, under the action of centrifugal force, it continuously rubs and squeezes with the multi-stage impeller of the high-pressure pump, so that the original granular urea particles are turned into powder, and finally are transported to the required blending tank, where they are further dissolved and clarified in the blending tank.

[0029] Embodiment 2

[0030] A feeding system includes an integrated feeder. The crushing mechanism in the integrated feeder is connected to a plurality of blending tanks to crush the urea particles in the mixture extracted from the mixing storage tank and then transport them to the corresponding blending tanks. That is to say, the integrated feeder and multiple blending tanks form a feeding production line, and the one-key start of the equipment simplifies the cumbersome operation process. After the equipment is started, the liquid inlet pump starts to supply water to the mixing tank. When the water supply volume reaches the required standard, the crushing pump automatically starts to operate and transports the urea mixture to the designated blending tank. After the equipment stops, the liquid inlet pump will stop immediately, while the crushing pump will still continue to operate for a period of time until all the remaining materials in the mixing tank are transported to the blending tank, and then the crushing pump automatically shuts down. Thus, all the urea blending and batching work is completed.

[0031] When multiple blending tanks are used simultaneously, all processes such as blending tank batching and filtration are controlled by solenoid valves. Just select the corresponding switch on the control panel to control each blending tank to complete various work requirements, reducing various error risks that may be caused by manual operation and having a lower error rate.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
