Embodiment 1

[0024] see figure 1 , a method and device for eliminating film-laying bulges on the floor of a salt field, the specific steps are as follows:

[0025] (1) Pond sun-drying: introduce raw brine on the bottom of the salt pan to sun-dry NaCl pool slabs, and the thickness of the pool slabs is 50cm;

[0026] (2) Leveling and rolling: leveling and rolling the bottom surface and side slope of the salt pan, after the side slope of the salt pan is compacted, spray raw brine until the surface is consolidated, and the spraying amount of raw brine is 1L per square meter of slope;

[0027] (3) Membrane laying: On the bottom surface and side slope of the salt pan, lay the membrane along the slope from the high ground to the low ground, and weld it. After the bottom surface is finished, excavate at the top edge of the salt pan slope Anchor ditch, bury one end of the salt field slope membrane into the anchor ditch to fix;

[0028] (4) Divide the bottom plate of the salt field after film layi...

Embodiment 2

[0032] see figure 1 , a method and device for eliminating film-laying bulges on the floor of a salt field, the specific steps are as follows:

[0033] (1) Pool slab drying: introduce raw brine on the bottom of the salt pan to dry NaCl pool slabs, the thickness of the pool slabs is 40cm;

[0034] (2) Leveling and rolling: leveling and rolling the bottom surface and side slope of the salt pan, after the side slope of the salt pan is compacted, spray raw brine until the surface is consolidated, the spraying amount of raw brine is 3L per square meter of slope;

[0035] (3) Membrane laying: On the bottom surface and side slope of the salt pan, lay the membrane along the slope from the high ground to the low ground, and weld it. After the bottom surface is finished, excavate at the top edge of the salt pan slope Anchor ditch, bury one end of the salt field slope membrane into the anchor ditch to fix;

[0036] (4) Divide the salt field bottom plate after film laying into 1,000 squa...

Abstract

The invention discloses a method and an apparatus for eliminating salt field bottom plate covering film bulges. The method comprises: 1, exposing a pool plate in the sun, wherein original brine is introduced on the bottom surface of a salt field to expose a NaCl pool plate in the sun; 2, carrying out flattening rolling, wherein the bottom surface and the slope of the salt field are subjected to flattening rolling; 3, paving with an anti-seepage film, wherein the bottom plates on the bottom surface and the slope of the salt field are respectively paved with plastic anti-seepage films; 4, dividing the salt filed bottom plate paved with the film into uniformly distributed rectangular unit areas by salt blocks, and fixedly connecting a one-way gas discharge valve to each unit area; 5, eliminating bulges before the brine enters, wherein the gas discharge interface of a gas discharge device is sealed by screwing a sealing screw nut after the bulge is eliminated; and 6, eliminating bulge after the brine enters, wherein the gas discharge interface of the one-way gas discharge valve is connected to a gas discharge soft pipe, the other end is connected to the gas inlet of a floating ball, and the sealing screw nut on the gas discharge outlet is opened, such that the gas discharge device can automatically discharge the gas. With the method and the apparatus of the present invention, the problem of the generation of a large number of bulges can be solved, the bulging phenomenon before and after the water entering can be eliminated, and the subsequent salt field production can be ensured.

Description

technical field [0001] The invention belongs to a method for eliminating film-laying bulges on the floor of salt pans, in particular to a method and a device for eliminating film-laying bulges on the floor of salt pans. Background technique [0002] The loss of brine resources caused by the seepage of salt pans is a technical problem encountered by many sodium salt and potassium salt production units. According to actual production experience, the seepage rate of Qinghai Salt Lake Salt Fields and Xinjiang Salt Lake Salt Fields in my country is about 0.5-0.8mm / d, and the loss of potassium resources caused by seepage reaches 20-50%, while the brine leaked from salt fields is infiltrating into the ground After being dispersed and absorbed, it is difficult to mine and recover again. Aiming at the cost increase and resource loss caused by salt pan seepage, technicians have conducted a large number of salt pan anti-seepage research and developed a large number of salt pan anti-see...
