Description

TECHNICAL FIELD

[0001] The utility model relates to aluminum silver paste production technical field, specifically, relate to a kind of aluminum silver paste production on-line detection sampling device. BACKGROUND

[0002] In the industrial production process, the surface of aluminum powder is treated in the reaction kettle to obtain aluminum silver paste. The sampling pipe is usually arranged below the reaction kettle, and it is not convenient for the staff to directly enter the lower part of the reaction kettle, so the sampling pipe usually extends outward for a long distance, and a sampling outlet is arranged on the sampling pipe. In the process of aluminum silver paste production, in order to continuously monitor the production status of aluminum silver paste, it is usually necessary to take samples several times during the reaction process.

[0003] During sampling, the sampling pipe may be contaminated by residual materials from the previous sampling or pipe wall attachments, affecting the accuracy of the sample, so that the sample cannot truly reflect the actual situation of the materials in the reaction kettle. Therefore, the staff flushes the sampling pipe by discharging a certain amount of aluminum silver paste from the sampling pipe first, and then takes samples; the discharged aluminum silver paste is usually directly stored in a waste liquid barrel, which not only wastes resources but also increases the cost of waste liquid treatment.

[0004] Therefore, it is an urgent need to develop an aluminum silver paste production on-line detection sampling device that can accurately sample and reduce waste liquid production to improve the production quality and efficiency of aluminum silver paste. UTILITY MODEL CONTENT

[0005] In view of the problem that a large amount of aluminum silver paste is needed to flush the sampling pipe to ensure sampling accuracy before sampling in the prior art, and the discharged aluminum silver paste is directly placed in a waste liquid barrel, which not only wastes resources but also increases the cost of waste liquid treatment, the utility model provides an aluminum silver paste production on-line detection sampling device.

[0006] To solve the above technical problems, the utility model solves them by the following technical schemes:

[0007] An aluminum silver paste production on-line detection sampling device includes a sampling pipe and a sampling outlet, the sampling pipe is fixed below the reaction kettle, a control valve is arranged on the sampling pipe, a recovery pipe is arranged between the control valve and the sampling outlet and communicates with the inner cavity of the sampling pipe, a recovery valve is arranged on the recovery pipe, a reflux pump is further arranged on the recovery pipe for pumping aluminum silver paste back to the reaction kettle, and a sampling valve is further arranged on the sampling pipe for controlling the opening and closing of the sampling outlet.

[0008] When sampling, the control valve and the recovery valve are opened, and the sampling valve is closed. The reflux pump is started, and the aluminum silver paste flows from the reaction kettle into the sampling pipe below under the action of gravity and the reflux pump, the sampling pipe is flushed to remove possible residues and pipe wall attachments, and then returns to the reaction kettle from the recovery pipe under the pump pressure provided by the reflux pump.

[0009] After a period of cleaning, the recovery valve is closed and the sampling valve is opened, and the aluminum slurry flows out of the sampling outlet under the action of gravity, and then the required sample is obtained from the sampling outlet for detection. After sampling, the control valve and the sampling valve are closed.

[0010] Before sampling, the pre-flushing operation can effectively avoid the influence of residues and pollution on the sample, and ensure that the taken sample can truly reflect the status of the aluminum slurry in the reactor. The aluminum slurry used for flushing is recovered to the reactor, which not only reduces the loss of raw materials, but also reduces the generation of waste liquid, and reduces the cost and burden of waste liquid treatment.

[0011] As a preferred, a pipeline sight glass is arranged on the sampling pipe between the control valve and the reactor.

[0012] When the sampling operation is performed, the flow of the aluminum slurry from the reactor to the control valve in the sampling pipe can be directly observed through the pipeline sight glass. Whether the sampling pipe is unobstructed can be determined.

[0013] As a preferred, a pipeline thermometer is arranged on the sampling pipe between the control valve and the reactor.

[0014] In the case that the sight glass cannot be seen clearly due to insufficient light at night or the like, the temperature of the pipeline is monitored through the pipeline thermometer. Usually, the aluminum slurry is heated during production, and when the aluminum slurry flows through the sampling pipe, the thermometer will show a high temperature; when there is no aluminum slurry flowing through, the temperature will be relatively low. The operator can determine whether the aluminum slurry is flowing according to the temperature change shown by the thermometer.

[0015] As a preferred, a pipeline flowmeter is arranged on the recovery pipe between the recovery valve and the reactor.

[0016] During the sampling and recovery of the aluminum slurry, the total flow of the aluminum slurry flowing back to the reactor from the recovery pipe can be known in real time by observing the pipeline flowmeter. Thus, it is ensured that the sampling pipe has been flushed by the aluminum slurry with sufficient flow before sampling.

[0017] As a preferred, the sampling pipe is bent downward at the sampling outlet to form a bent portion.

[0018] By using the downward bending structure, the direction of the sampling outlet is changed. When an unexpected situation of sudden damage of the valve occurs during sampling, the sprayed aluminum slurry changes the flow direction due to the existence of the bent portion, and does not directly spray far forward, but flows downward, thereby limiting the spraying distance and range to a certain extent. The safety of the sampling personnel is ensured

[0019] As a preferred, a sampling hose is sleeved on the sampling pipe at the sampling outlet, and the sampling hose is fixed on the sampling pipe by using a cable tie.

[0020] The flexibility and bendability of the sampling tubing facilitate sample flow and collection. The cable ties ensure a tight and reliable connection between the tubing and the sampling tube.

[0021] As a preferred option, it also includes a recycling bin, the upper surface of which has a recycling port for inserting a sampling hose.

[0022] After sampling, some aluminum silver paste will remain in the sampling tube. If this aluminum silver paste drips down, it will contaminate the production site. Therefore, a recycling bin is set up. After sampling, the tube is inserted into the recycling bin to recover the dripping aluminum silver paste. Attached Figure Description

[0028] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0029] Example

[0030] like Figs. 1-3 As shown in the figure, the online detection and sampling device for aluminum silver paste production disclosed in this embodiment mainly consists of a sampling tube 110, a control valve 1101, a pipe sight glass 1103, a pipe thermometer 1104, a recovery tube 120, a reflux pump 1202, a recovery valve 1201, a sampling valve 1102, a sampling outlet, a bend 1105, a sampling hose 130, and a recovery tank 140.

[0031] The reactor body 150 is used for the production of aluminum silver paste. A sampling tube 110 is fixed below the reactor body 150, and from the end closest to the reactor body 150, a control valve 1101, a sight glass 1103, and a thermometer 1104 are sequentially installed on it. Between the control valve 1101 and the sampling outlet, a recovery tube 120 is provided, communicating with the inner cavity of the sampling tube 110. The other end of the recovery tube 120 extends into the reactor body 150. A recovery valve 1201 and a reflux pump 1202 are installed on the recovery tube 120, as is a flow meter 1203. A sampling valve 1102 is located near the sampling outlet of the sampling tube 110. The sampling tube 110 bends downwards at the sampling outlet to form a bend 1105, and a sampling hose 130 is fitted at the outlet and secured with a cable tie. In addition, a recovery tank 140 is provided, with a recovery port on its upper surface for inserting the sampling hose 130.

[0032] The operating principle of the online detection and sampling device for aluminum silver paste production in this embodiment is as follows:

[0033] Before sampling, open control valve 1101 and recovery valve 1201, close sampling valve 1102, and start reflux pump 1202. Under the action of gravity and reflux pump 1202, aluminum silver paste flows from reactor body 150 into sampling pipe 110 to flush it and remove residues and attachments. Then it returns to reactor body 150 through recovery pipe 120.

[0034] After rinsing for a period of time, the recovery valve 1201 and the reflux pump 1202 are closed, and the sampling valve 1102 is opened. The aluminum silver paste flows out from the sampling outlet under gravity, and a sample is obtained through the sampling outlet for testing. The pipe sight glass 1103 and the pipe thermometer 1104 work together to determine whether the aluminum silver paste has flowed through the sampling tube 110. The total flow rate of the aluminum silver paste returning to the reactor body 150 is monitored in real time by the pipe flow meter 1203 on the recovery pipe 120 to ensure that there is sufficient flow to rinse the sampling tube 110 before sampling.

[0035] After sampling is completed, close control valve 1101 and sampling valve 1102, and insert sampling hose 130 into the recycling port of recycling bin 140.

[0036] Pre-rinsing effectively avoids the impact of residues and contamination on the samples, ensuring that the samples accurately reflect the condition of the aluminum silver paste inside the reactor body 150. The aluminum silver paste used for rinsing is recycled back to the reactor body 150, reducing raw material loss, waste liquid generation, and alleviating waste liquid treatment costs and burdens.

[0037] In summary, the above are merely preferred embodiments of this embodiment. All equivalent changes and modifications made in accordance with the scope of the patent application of this embodiment shall fall within the scope of the patent of this embodiment.
