Description

Technical Field

[0001] The utility model relates to a brine sampler, in particular to the structure of a brine sampler for a salt field. Background Art

[0002] Brine is a liquid mineral resource containing potassium, magnesium, sodium and other ions. The brine mined from the strata is dried in the salt pans, that is, according to the drying evaporation and concentration of the brine and the crystallization of minerals in the brine, the discharge and drying time of the brine are regulated, so that the brine gradually precipitates salt minerals such as sodium chloride, potassium salt, carnallite, and magnesium chloride. The potassium salt ore (carnallite ore, etc.) with higher purity that meets the production needs is sent to the potash fertilizer processing workshop for processing, and products with economic value such as potash fertilizer can be obtained.

[0003] In the salt field production process, the detection of brine data plays an important role in the salt field production process. Because brines of different specific gravities are stratified in salt fields and brine mining channels, the mineral components contained in the brine at each layer are quite different, so it is necessary to collect brine samples at multiple depths to detect the Baume degree of the brine and the component content of each ion in the brine.

[0004] Traditional brine samplers are difficult to seal underwater. During the process of the sampler entering and taking out brine, brine from other layers (depths) will enter from the openings on the sampler, contaminating the brine samples of a specific depth that have been obtained in the sampler, affecting the composition of the brine samples, causing distortion of the brine sampling data, affecting the test results, and easily leading to disruptions in the salt field production process control. Utility Model Content

[0005] The utility model aims to solve the problem that the existing sampler is difficult to seal underwater, which causes the brine sample to be easily contaminated by brine at other depths, thus affecting the detection result.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a brine sampler, including a cylinder 1, a measuring rope 5, a switch pull rope 6, a central pull rod 2, and a sealing gasket 201.

[0007] The upper end of the cylinder 1 is closed, and a sampling hole 102 and a sliding positioning sleeve 101 communicating with the interior of the cylinder 1 are formed on the top wall 11. The lower part of the cylinder 1 is closed, and an openable and closable sample opening 4 is formed on the side wall or the bottom.

[0008] One end of the measuring rope 5 is fixed to the upper outer portion of the cylinder 1 .

[0009] The center rod 2 is installed inside the cylinder 1 and fixedly connected to the sealing gasket 201 . The upper end of the center rod 2 passes through the sliding positioning sleeve 101 and is exposed to the outside. It is fixedly connected to one end of the switch pull rope 6 . The center rod 2 can slide up and down along the sliding positioning sleeve 101 .

[0010] The sealing gasket 201 is parallel to the top wall 11 and covers the injection hole 102 .

[0011] Therefore, the switch pull rope 6 can be used to control the movement of the central pull rod 2, thereby controlling the position of the sealing gasket 201, so that the sampling hole 102 can be opened and closed as needed. During the sampling process, the staff can hold the measuring rope 5 and the switch pull rope 6, and control the sealing gasket 201 to close the sampling hole 102 when the cylinder 1 is at a non-sampling depth, so as to ensure that the sampling is not contaminated. When the cylinder 1 reaches a specified depth, the sealing gasket 201 is moved down to open the sampling hole 102, so that the brine at the specified depth can be collected, and the sampling effect is good, and the accuracy and efficiency are high.

[0012] Preferably, a central support frame 3 is fixedly provided in the middle of the cylinder body 1 , a through hole is formed in the center of the central support frame 3 and is located directly below the sliding positioning sleeve 101 , and the central pull rod 2 passes through the through hole.

[0013] Since the central support frame 3 can play a guiding role, the central pull rod 2 will not deviate when moving up and down, so it can ensure that the sealing gasket 201 can be aligned with the annular sealing platform 103 to ensure the sealing effect.

[0014] Preferably, a measuring rope fixing ring 13 is formed on the upper side of the cylinder 1, and the measuring rope fixing ring 13 is symmetrical with respect to the center line of the cylinder 1. One end of the measuring rope 5 forms a branch corresponding to the measuring rope fixing ring 13, and is fixed to each measuring rope fixing ring 13 respectively.

[0015] Therefore, the measuring rope 5 can stably pull up or move the cylinder 1, and ensure to the greatest extent that the cylinder 1 will not tilt or overturn during the movement, causing the brine therein to spill out.

[0016] Preferably, the measuring rope 5 is provided with a scale.

[0017] Therefore, the depth of the brine sampler can be determined based on the readings on the measuring rope 5.

[0018] Preferably, handles are provided at the upper ends of the measuring rope 5 and the switch pull rope 6, respectively, to facilitate the staff to hold them.

[0019] Preferably, the sealing pad 201 is a silicone pad, the central pull rod 2 is fixedly connected to the sealing baffle 202 , the sealing baffle 202 is perpendicular to the center line of the central pull rod 2 , and the sealing pad 201 is fixedly arranged on the upper side of the sealing baffle 202 .

[0020] The silicone material has better sealing properties and can withstand the pressure generated by the brine sampler as it descends in the brine, thus maintaining the accuracy of brine sampling.

[0021] Preferably, the lower part of the central tie rod 2 forms a screw rod 205, which is thinner than the upper part of the central tie rod 2, forming a card platform structure, and the sealing gasket 201 and the sealing baffle 202 are plates with a mounting hole formed in the center, and the sealing gasket 201 and the sealing baffle 202 are detachably fixed on the screw rod 205 by the fixing nut 204 and the card platform structure. An annular sealing platform 203 matching the shape of the sealing gasket 201 is formed on the lower side of the top wall 11.

[0022] Since the sealing gasket 201 is made of a relatively soft material, the sealing baffle 202 can fix the sealing gasket 201 and provide support for the sealing gasket 201. The annular sealing platform 203 can protect the sealing baffle 202 and prevent the friction force generated when the fixing nut 204 is screwed from scratching the sealing baffle 202 and the fixing nut 204.

DETAILED DESCRIPTION

[0034] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. The following description is a concretization of the claims of the present invention.

[0035] Figure 1 It is a diagram illustrating the external structure of the brine sampler; Figure 2 It is a diagram illustrating the internal structure of the brine sampler; Figure 3 This is a cross-sectional illustration of the brine sampler cut along the central axis. Figures 1 to 3 A brine sampler is described.

[0036] like Figure 1 As shown, the brine sampler for salt fields includes a cylinder 1, a central pull rod 2, a sealing gasket 201, a measuring rope 5, and a switch pull rope 6.

[0037] like Figure 1 As shown, the upper end of the cylinder 1 is closed by the top wall 11, and the top wall 11 is formed with an injection hole 102 and a sliding positioning sleeve 101, the sliding positioning sleeve 101 extends upward from the top wall 11, and the lower part of the cylinder 1 forms an openable and closable sample placement port 4, the sample placement port 4 is provided with a latex tube 403, and the latex tube 403 is provided with a water stop clamp 401, and the upper part of the cylinder 1 is connected to one end of the measuring rope 5.

[0038] When sampling brine, the water stop clamp 4 is in a normally closed state, and the brine can enter the interior of the cylinder 1 through the sampling hole 102 and be stored. After the brine is successfully taken, the water stop clamp 401 is opened, and the brine can flow out from the latex tube 403.

[0039] like Figures 1-2 As shown, the upper end of the straight rod center pull rod 2 is fixedly connected to one end of the switch pull rope 6, and the lower part passes through the sliding positioning sleeve 101 and is fixedly connected to the sealing gasket 201. The center pull rod 2 can slide up and down along the sliding positioning sleeve 101, and the cross section of the sealing gasket 201 covers the cross section of the injection hole 102.

[0040] Pulling the switch pull rope 6 upwards drives the center pull rod 2 to move upwards, and the sealing gasket 201 moves upwards accordingly, close to the inner side of the top wall 11, covers each injection hole 102, and can seal all the injection holes 102. Loosening the switch pull rope 6, the brine can enter the interior of the cylinder 1 through the injection hole 102.

[0041] like Figure 2 As shown, a central support frame 3 is fixedly arranged in the middle of the cylinder 1, and a through hole is formed in the center of the central support frame 3 and is located directly below the sliding positioning sleeve 101, and the central pull rod 2 passes through the through hole.

[0042] Figure 4 Is the brine sampler along Figure 3 The sectional illustration of the AA section; Figure 5 Is the brine sampler along Figure 3 The cross-sectional view of the BB is shown in Figure 1. Figures 3 to 5 As shown, from a top view, the sealing gasket 201 covers each injection hole 102 , and when the sealing gasket 201 is in contact with the top wall of the cylinder 1 , all the injection holes 102 can be sealed. Figure 4 The oblique line portion represents the annular sealing platform 103 formed at the lower part of the top wall of the cylinder. Figure 3 From the perspective of the annular sealing platform 103, the shape of the sealing gasket 201 matches the shape of the sealing gasket 201, so that the outer edge of the sealing gasket 201 can fit with the inner edge of the annular sealing platform 103, and the sealing effect is good.

[0043] like Figure 5 As shown, the central support frame 3 is composed of three support ribs and a circular ring, and a through hole with a hole diameter larger than the outer diameter of the lower part of the central tie rod 2 is formed in the center of the circular ring, so that the lower part of the central tie rod 2 can slide up and down along the through hole. The central support frame 3 can play a guiding role, so that the central tie rod 2 will not deviate when moving up and down, ensuring that the sealing gasket 201 can be aligned with the annular sealing platform 103, thereby ensuring the sealing effect.

[0044] Figure 6 is an exploded diagram of the center tie rod 2, as shown in Figure 6 As shown, the sealing gasket 201 and the sealing baffle 202 are plates with a mounting hole formed in the center, and the sealing gasket 201 and the sealing baffle 202 are detachably fixed on the screw 205 by the fixing nut 204 and the clamping structure. Since the sealing gasket 201 is made of a relatively soft material, the sealing baffle 202 can fix the sealing gasket 201 and provide support for the sealing gasket 201.

[0045] An annular sealing platform 203 is provided between the sealing baffle 202 and the fixing nut 204 , which can protect the sealing baffle 202 and prevent the friction force generated when the fixing nut 204 is screwed from scratching the sealing baffle 202 and the fixing nut 204 .

[0046] Figure 7 This is a diagram illustrating the use of the brine sampler sealed into the brine; Figure 8 This is a diagram illustrating the use of the brine sampler when it is opened to absorb brine; Fig. 9 This is a diagram showing the resealing status of the brine sampler. Figures 7 to 9 , the use of the brine sampler is explained (taking the acquisition of 6m deep brine samples as an example).

[0047] Before sampling, close the water stop clamp 4 first, then Figure 7 As shown, the staff on the shore controls the (portable) measuring rope 5 and the switch pull 6, keeps the sealing gasket 201 sealing the top wall 11, and places the cylinder 1 to a position where the liquid level depth is 6m.

[0048] Afterwards Figure 8 As shown, release the switch and pull up 6, so that the sealing gasket 201 moves down, and the injection hole 102 on the top wall 11 (see Figure 4 ) is opened, and the brine (sample) with a liquid level depth of 6m enters the cylinder 1 from the sampling hole.

[0049] Afterwards Fig. 9 As shown, pull the switch puller 6 upward to move the sealing gasket 201 upward and seal the sampling hole 102 on the top wall 11, then pull the measuring rope 5 and the switch puller 6 upward, keep the top wall 11 sealed and lift the cylinder 1 ashore, then open the water stop clamp 4 to release the sample.

[0050] Therefore, if Figure 7 , Fig. 9 As described above, before and after the position where the liquid level depth is 6 m, the injection hole 102 is sealed with the sealing gasket 201 to ensure that the sample is not contaminated.

[0051] The switch pull rope 6 can control the movement of the central pull rod 2, thereby controlling the position of the sealing gasket 201 and determining the opening and closing of the sampling hole 102. This enables the brine sampler to have the function of multi-layer depth brine sampling, and can collect brine of a specified depth with good sampling effect, high accuracy and efficiency.
