Technical field

The utility model relates to a kind of sampling thief, is specifically related to a kind of jar of vertical sampling thief down.

Background technology

In petroleum chemical industry, raw materials for production and finished product generally are stored in the jar, in order to obtain the sampling parameters of liquid in the jar, different parts collected specimens that need be in jar, artificial sample is wasted time and energy and is difficult to collect the sample that satisfies the sampling position, and Chinese patent ZL2008200366041 discloses a kind of jar of collector down, but when tank level descends, the sampling error of collection point is than higher, and its sampled result can not satisfy the demands.

Summary of the invention

The utility model has overcome the deficiencies in the prior art, has proposed a kind of jar of vertical sampling thief down, and the utility model aim is: by the set pulley blocks of sampling mechanism, grab sampling is avoided stochastic error accurately and reliably, improves the sampling work efficiency.

In order to solve the problem that prior art exists, the utility model by the following technical solutions:

The utility model is provided with a sampling hose set, a brace summer, a ball float and an acquisition processing device, described sampling hose set comprises top sampling flexible pipe, middle part sampling flexible pipe, bottom sampling flexible pipe, one meter sample flexible pipe and bottom sampling flexible pipe end of apart from, one end of described brace summer is fixed on the ball float bottom, its other end is fixed on the power-assisted rope, the other end of power-assisted rope is fixed on a side wall upper part of tank body, brace summer top fastening a tracker, a fixed pulley is fixed near ball float one side in the centre of brace summer, and the below of fixed pulley is provided with a travelling block; Another side wall upper part of tank body is provided with a fixed pivot, is a stay cord on the described fixed pivot, after the other end of stay cord is walked around travelling block and fixed pulley successively, is fixed on the described travelling block.Described travelling block both sides are provided with a U-shaped frame, two end points of described U-shaped frame be separately fixed at travelling block about on two axles, the right lower quadrant of described U-shaped frame is being tied up the middle part sampled point of middle part sampling flexible pipe; The lower left quarter of described U-shaped frame is fixed one and is gathered rope, the bottom sampled point of bottom sampling flexible pipe is being tied up in the position, lower middle of described collection rope, the end of described collection rope is being tied up the bottom sampled point of bottom sampling flexible pipe, at 1/2nd places of the end and the intermediate distance of described collection rope, tying up one meter sampled point of the one meter sampling flexible pipe end of apart from the end of apart from.

Fix another root collection rope on the described tracker, the other end of described collection rope is being tied up the top sampled point of top sampling flexible pipe.

The other end of five flexible pipes of described sampling hose set seals respectively and is fastened on the described hose connection.

Described hose connection is provided with five operation valves.

Described brace summer is made by anticorrosive material (as stainless-steel tube).

The utlity model has the advantage of following four aspects:

1, collection has replaced manually automatically, safe ready;

2, collector does not need extra sampling instrument, and is time saving and energy saving;

3, adopt the sampling of fixed pulley and travelling block combination form, five collection points are set, fixed point is reliable, and sampling accurately and reliably.

Description of drawings

Further specify the utility model below in conjunction with the drawings and specific embodiments.

Fig. 1 is a loading schematic flow sheet of the present utility model.

Fig. 2 is a control signal connection diagram of the present utility model.

Among the figure, 1. tank body; 2. power-assisted rope; 3. tracker; 4. brace summer; 5. ball float; 6. fixed pulley; 7. stay cord; 8. travelling block; 9. middle part sampled point; 10. bottom sampled point; 11. sampling hose set; 12. acquisition processing device; 13. hose connection; 14. bottom sampled point; 15. one meter sampled point the end of apart from; 16. top sampled point; 17.U shape frame; 18. operation valve.

Embodiment

Consult shown in Figure 1, harvester has been installed in tank body 1 inside, harvester is fixed on tank body 1 interior two relative tank skin tops, 2 pairs of harvesters of power-assisted rope by two point of fixity and plays auxiliary pulling force effect, under the buoyancy of ball float 5, five sampled point relative positions are fixed, and tracker 3 is fastened on the brace summer 4, have occupied the two ends of brace summer respectively with ball float 5, described brace summer 4 is made by anticorrosive material, can be stainless steel material; Under equilibrium state, fixed pulley 6 and travelling block 8 remain static, stay cord 7 has remained static, at this moment, top sampled point 16 is at sixth place, the top of liquid level, and middle part sampled point 9 is at 1/2nd places, and bottom sampled point 10 is at bottom sixth place, the end of apart from one meter sampled point 15 in the bottom one meter, the bottom sampled point is in the bottom; When liquid level reduces, ball float descends, power-assisted rope 2 moves around circular path, because the effect of travelling block, the position of sampled point changes, and when liquid level reaches new equilibrium position, ball float reaches a new fixed position, each sampled point arrives a new balance, it is apart from the proportionate relationship basic fixed of liquid level, and sampling hose set 11 is connected to acquisition processing device 12 by hose connection 13.

When collecting work began, a certain road operation valve in the hose connection 13 was opened, the electric motor starting in the acquisition processing device 12, sample extracts in the sampling flexible pipe of institute's gating, by opening different operation valves, but the different sampled point of gating, to reach the sampling purpose.

Consult shown in Figure 2ly, travelling block is provided with a U-shaped frame, so that fixing collection point and gather flexible pipe.

Consult shown in Figure 3, hose connection 13 comprises five operation valves 18 and some flanges, described operation valve 18 once can only be opened an operation valve, thereby once have only the sample of a collection point to flow into acquisition processing device 12, described operation valve 18 can also can be opened by the electric device of acquisition processing device 12 by artificial unlatching.
