DETAILED DESCRIPTION

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] First Embodiment

[0025] like Figure 1 As shown, this utility model provides a technical solution: a sampling device for detecting industrial sulfuric acid production, including a central collector 1. The volume of the central collector 1 should be moderate. If it is too large, it will affect the suction force when the air bag 6 is pressed. If it is too small, it will cause the liquid to accumulate. The central collector 1 is provided with an inlet tube 2 and an outlet tube 3 on its upper and lower sides, respectively. There are multiple outlet tubes 3, and each outlet tube 3 is provided with an outlet control valve 4.

[0026] A collection dish 5 is provided at the bottom of the sample tube 3. A scale line 7 is provided on the collection dish 5. A discharge port 8 is provided at the bottom of the collection dish 5. A discharge control valve 9 is provided on the discharge port 8.

[0027] The top of the central collector 1 is also provided with a flushing port 10, and a flushing control valve 11 is provided on the flushing port 10.

[0028] Sample inlet tube 2 is a straight-insertion tube, which can be directly connected to the storage container containing sulfuric acid to collect samples.

[0029] Connect the top of the injection tube 2 to the outlet of the sulfuric acid storage device (not shown in the figure). Sulfuric acid flows into the central collector 1 through the injection tube 2. According to specific needs, open the corresponding liquid outlet control valve 4 so that the sulfuric acid flows into the corresponding collection dish 5 through the corresponding sample outlet tube 3. The volume is controlled by the scale line 7 on the collection dish 5.

[0030] Then connect the sampling tube (not shown in the figure, usually a glass test tube) to the corresponding discharge port 8, open the discharge control valve 9, and control the amount of sulfuric acid flowing into the sampling tube through the scale line 7 to complete the sampling.

[0031] During cleaning, open the flushing control valve 11 and pour in cleaning water through the flushing port 10 to first clean the inside of the central collector 1. Then, open the liquid outlet control valve 4 and the cleaning liquid flows down to clean the sample outlet tube 3 and the collection dish 5. Finally, open the discharge control valve 9 to clean the sampling tube, thereby achieving integrated cleaning and simplifying the cleaning process.

[0032] The second embodiment differs from the first embodiment in that it provides an alternative sampling method.

[0033] As Figure 2 shown, the sample inlet tube 2 is a hose 22, and the head of the hose 22 is provided with a sampling nozzle 23 with a sharp beak.

[0034] The sample outlet tube 3 is provided with a pressurized air bag 6 near the collection dish 5, which is arranged obliquely upward to avoid liquid flowing into the pressurized air bag 6, or a gas-liquid separator can also be built-in. The volume of the pressurized air bag 6 should be moderate, at least one pressurized air bag 6 can complete the sampling purpose by single pressing.

[0035] The middle part of the sample outlet tube 3 is provided with a manifold 15, and the manifold 15 is provided with an on-off valve 16.

[0036] When the middle and upper layer liquid inside the sulfuric acid storage is needed to be sampled, the sampling nozzle 23 is inserted into the middle and upper layer liquid, the liquid outlet control valve 4 at the corresponding position is opened, and the pressurized air bag 6 below the position is pressed, so that the sampling nozzle 23 generates a negative pressure suction force, the sulfuric acid liquid is sucked into the central collector 1, and then flows into the collection dish 5 at the corresponding position.

[0037] When multiple sulfuric acid storage is needed to be sampled at the same time, the manifold 15 at different positions is connected to different sulfuric acid storage, the on-off valve 16 is opened, so that multiple collection dishes 5 simultaneously sample multiple sulfuric acid storage (at this time, the sample inlet tube 2 can not be used for sampling), which fully meets different sampling requirements.

[0038] When cleaning, the same way is installed for cleaning.

[0039] The third embodiment is different from the first and second embodiments in that another flushing mechanism is provided

[0040] As Figure 3 shown, the top of the central collector 1 is provided with a filling port 12, the filling port 12 is provided with a filling control valve 13, and the top of the filling port 12 is provided with a neutralizing tank 14.

[0041] In order to improve the cleaning effect, the neutralizing tank 14 contains neutralizing liquid (generally alkaline liquid), during cleaning, the filling control valve 13 is opened synchronously, so that the neutralizing liquid in the neutralizing tank 14 flows into the central collector 1, the neutralizing liquid and the cleaning water are mixed, so as to neutralize the residual sulfuric acid, generate neutral and non-toxic sulfate and water, and then be discharged, thereby reducing pollution.

[0042] Meanwhile, the contents not described in detail in the specification all belong to the existing technology known to those skilled in the art.

[0043] To sum up, the sampling device for industrial sulfuric acid production detection, by adopting the structure of one central collector plus multiple collection dishes, can realize the purpose of sampling multiple sampling tubes simultaneously in one time, of course, according to the requirement, only one or more liquid outlet control valves can be opened to sample one or more sampling tubes; further, by setting the collection dish with scale, the sampling capacity can be accurately controlled; further, by setting the flushing port and neutralization tank, a plurality of collection mechanisms can be directly and uniformly cleaned through the central collector, thereby reducing the workload.
