Description

Technical Field

[0001] This utility model relates to the field of methyl acrylate extraction technology, specifically to a methyl acrylate extraction and separation tower. Background Technology

[0002] Methyl acrylate is an organic compound that is slightly soluble in water. In the production process, it separates into layers with water and is extracted using extraction. In the extraction process of methyl acrylate, an methyl acrylate extraction tower is used. However, when the extracted material is separated into liquids, the bottom material is discharged from the bottom of the extraction tower first. This can easily lead to the problem of excessive discharge with the upper material, which cannot achieve effective separation in a convenient and accurate manner. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a methyl acrylate extraction and separation tower, which solves the problem of excessive extraction and resulting mixture mixing during the extraction process.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a methyl acrylate extraction and separation tower, comprising a storage tank, a separation tower body connected to the lower end of the storage tank, a sedimentation tank connected to the output end of the separation tower body, and the sedimentation tank connected to the output channel of the extract.

[0005] The sedimentation tank includes a first tank body and a second tank body. The installation height of the first tank body is greater than that of the second tank body. The first tank body is provided with a material receiving port and a material guiding port. The second tank body is provided with a material receiving port with a height equal to that of the material guiding port. The second tank body is provided with an output port that is opposite to the material receiving port. The opening height of the output port is less than that of the material receiving port.

[0006] The first tank and the second tank are fitted with an outer sleeve. The outer sleeve includes an outer ring sleeve that fits into the first tank and an armature sleeve that fits into the second tank. The outer ring sleeve and the armature sleeve are connected to form a support for the first tank and the second tank.

[0007] The output end of the separation tower is connected to the receiving port through a material conveying pipe.

[0008] In one embodiment, the separation tower body includes a plurality of tower tanks and a connecting sleeve installed on the tower tanks for connecting adjacent tower tanks. The tower tank at the bottom end has an observation window on its tank body, and a feed port connected to and communicating with a feed pipeline is opened on the tank body together with the observation window. The tower tank at the top end is connected to a storage tank.

[0009] The support sleeve is surrounded on the side wall of the bottommost tower tank. The support sleeve extends downward and connects with the connecting ring sleeve through an extension arm to expand the support area.

[0010] In one embodiment, the connection point between the conveying pipe and the receiving port is located above the centerline of the side wall of the first tank, and a monitoring window for observing the stratification state is provided on the same side of the side wall of the first tank where the receiving port is located.

[0011] In one embodiment, the feed inlet is located below the centerline of the first tank, the receiving inlet is located above the centerline of the second tank, and an output pipe is connected to the output port.

[0012] In one embodiment, the extension arm extends in an L-shape between the outer ring sleeve and the support sleeve, and the support sleeve is in the shape of a ring plate with its inner wall conforming to the side wall structure of the tank.

[0013] In one embodiment, both the feed pipe and the output pipe are equipped with shut-off valves to control the output of the extract.

[0014] Compared with the prior art, the present invention provides a methyl acrylate extraction and separation tower, which has the following advantages:

[0015] In the technical solution disclosed in this utility model, based on the existing situation where the output is greater than the stratification amount, this solution connects a sedimentation tank to the output extract channel to further intercept and precipitate the extract that has been output from the separation tower, thereby increasing its controllability in the overall extraction separation tower device and increasing the purity of the output extract.

[0016] Based on the setting of a sedimentation tank, this utility model, in order to increase the overall connection between the sedimentation tank and the split tower body and the supporting effect of the sedimentation tank itself, sets up a support sleeve and an extension arm to connect with the outer sleeve sleeved outside the sedimentation tank, thereby increasing the contact area between the outer sleeve and the pre-set ground, and effectively improving the supporting stability effect of the outer sleeve on the sedimentation tank.

[0025] Figures 1-4 This embodiment addresses the specific problem of methyl acrylate, an organic compound slightly soluble in water. During production, it separates from water, requiring extraction. The extraction process uses an methyl acrylate extraction tower. However, existing towers, when separating the extracted material, discharge the bottom layer first, which can lead to excessive discharge containing upper layer material, hindering efficient and accurate separation. To address this issue of excessive extraction causing mixing, this solution provides a methyl acrylate extraction separation tower. A sedimentation tank 3 is connected to the output channel of the tower body 2 to further intercept and precipitate the extract, increasing controllability within the overall extraction separation tower device and improving the purity of the output extract.

[0026] A methyl acrylate extraction and separation tower is provided with a storage tank 1 for storing the raw liquid of methyl acrylate to be extracted. The lower end of the storage tank 1 is connected to a separation tower body 2 for settling and stratification. The output end of the separation tower body 2 is connected to a sedimentation tank 3. The sedimentation tank 3 is connected to the output channel of the extract to transport the extract to an ideal storage location in the outside.

[0027] The sedimentation tank 3 includes a first tank body 31 and a second tank body 32. The installation height of the first tank body 31 is greater than that of the second tank body 32. The first tank body 31 has a receiving port 33 and a guiding port 34. The second tank body 32 has a receiving port 35 with a height equal to that of the guiding port 34. The second tank body 32 also has an output port 36, which is opposite to the receiving port 35 and has a lower opening height than the receiving port 35. The guiding port 34 is located below the centerline of the first tank body 31, and the receiving port 35 is located above the centerline of the second tank body 32. An output pipe 37 is connected to the output port 36. The output end of the separation tower 2 is connected to the receiving port 33 through a conveying pipe 4, so that the extract output from the separation tower 2 enters the first tank body 31 through the conveying pipe 4. Both the conveying pipe 4 and the output pipe 37 are equipped with shut-off valves to control the output of the extract. The material conveying pipe 4 and the receiving port 33 are located above the centerline of the side wall of the first tank 31, and a monitoring window for observing the stratification state is provided on the same side of the side wall of the first tank 31 where the receiving port 33 is located. An outer sleeve 38 is fitted onto the first tank 31 and the second tank 32. The outer sleeve 38 includes an outer ring sleeve 381 that fits onto the first tank 31 and an connecting ring sleeve 382 that fits onto the second tank 32. The outer ring sleeve 381 and the connecting ring sleeve 382 are connected, and the connection between the connecting ring sleeve 382 and the ground forms direct support for the second tank 32 and indirect support for the first tank 31.

[0028] The separation tower body 2 includes several tower tanks 21 and connecting sleeves 22 installed on the tower tanks 21 for connecting adjacent tower tanks 21. The tower tank 21 at the bottom end has an observation window 23 on its tank body, and a feed port connected to and communicating with the feed pipeline 4 is opened on the tank body together with the observation window 23. The tower tank 21 at the top end is connected to the liquid storage tank 1. In order to increase the overall connection between the sedimentation tank 3 and the separation tower body and the supporting effect of the sedimentation tank 3 itself, a support sleeve 24 is surrounded on the side wall of the tower tank 21 at the bottom end. The support sleeve 24 is in the shape of a ring plate, and its inner wall is set to follow the shape of the side wall structure of the tank body to increase the contact area with the tower tank 21. The support sleeve 24 extends downward and connects with the connecting sleeve 382 through the extension arm 25 to expand the supporting area. The extension arm 25 is L-shaped and extends between the outer ring sleeve 381 and the support sleeve 24, thereby increasing the contact area between the outer sleeve 38 and the pre-set ground, effectively improving the supporting stability effect of the outer sleeve 38 on the sedimentation tank 3.
