[0001] The utility model relates to the technical field of vacuum buffer tanks, in particular to a vacuum buffer tank for extracting turpentine. Background Art

[0002] Turpentine, also known as rosin oil or rosinol, is a natural volatile oil extracted from the resin of pine trees. It is primarily composed of terpenes and has a distinctive pine aroma. Turpentine is widely used in the pharmaceutical, chemical, and daily chemical industries.

[0003] For example, a vacuum buffer tank for extracting turpentine from rosin disclosed in authorization announcement number CN216998323U includes a vacuum tank, a liquid outlet is provided at the center of the bottom of the vacuum tank, support legs are fixedly connected by bolts near the four corners of the bottom of the vacuum tank, an air inlet pipe is provided near the left side of the top of the vacuum tank, an air outlet pipe is provided to the right of the air inlet pipe, one end of the air outlet pipe passes through the top of the vacuum tank and communicates with the inner cavity of the vacuum tank, and a cooling mechanism is provided inside the vacuum tank. After adopting the above technical solution, the beneficial effect of the utility model is that by providing the cooling mechanism, the device can conveniently control the condensation speed, thereby improving the work efficiency of the user.

[0004] Although the above patent can conveniently control the condensation speed, grease easily accumulates as an oil film on the inner wall of the vent in the cooling block. When the thickness of the oil film exceeds a certain level, it will affect the normal use of the vent. However, the above device does not have an anti-blocking mechanism. Utility Model Content

[0005] The purpose of the utility model is to provide a vacuum buffer tank for extracting turpentine, so as to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A vacuum buffer tank for extracting turpentine, comprising

[0008] A buffer tank body, wherein the top of the buffer tank body is connected to a vacuum pipe, and the middle of the bottom end of the buffer tank body is connected to an injection pipe;

[0009] A condensation mechanism is provided at the middle portion of the inner side of the buffer tank body, and an anti-blocking mechanism is provided at the upper end of the buffer tank body close to the condensation mechanism.

[0010] Preferably, the condensing mechanism includes a cooling block, which is fixedly mounted on the inner middle portion of the buffer tank body. A pipe groove is provided in an annular shape on the outer wall of the cooling block, and a cold water pipe is provided in an annular shape inside the pipe groove.

[0011] Preferably, the condensing mechanism further comprises a cooling groove, the cooling groove being regularly opened in the middle of the cooling block, and the cooling block and the injection pipe being on the same central axis;

[0012] Preferably, the anti-blocking mechanism includes a movable plate with a hole, which is movably installed on the upper part of the buffer tank body, and a plurality of sleeve rods are regularly provided at the bottom end of the movable plate with a hole, and the sleeve rods are movably connected to the cold guide groove;

[0013] Preferably, the anti-blocking mechanism further comprises guide rods, the guide rods being arranged on the four sides of the upper end of the cooling block and the buffer tank body, the four guide rods being movably sleeved with the four sides of the movable disk with holes, and the buffer tank body and the movable disk with holes being provided with springs outside the guide rods;

[0014] Preferably, the four corners of the bottom end of the buffer tank body are provided with supporting feet, and the two sides of the buffer tank body close to the injection pipe are provided with oil outlet pipes.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. A vacuum buffer tank for extracting turpentine, which is used in conjunction with a perforated movable disk, a cooling groove, a sleeve rod and a spring. When the compression pump injects gas into the buffer tank body from the injection pipe, the air pressure at the lower end of the cooling block is greater than the air pressure at the upper end, so the sleeve rod is lifted by the entering gas until the sleeve rod exits from the upper end of the cooling groove and compresses the spring. When the extraction is completed, external gas is reversely injected into the buffer tank body from the vacuum pipe. The compressed spring rebounds to control the sleeve rod to be inserted into the cooling groove from top to bottom, and the oil film formed in the cooling groove is discharged from the bottom, thereby avoiding blockage.

[0017] 2. A vacuum buffer tank for extracting turpentine, which is used in conjunction with a buffer tank body, a vacuum pipe, an injection pipe and a movable disk with holes. This device is used to extract turpentine from rosin. During extraction, an external vacuum pump is started to form a negative pressure inside the buffer tank body, and the gas generated by the combustion of rosin is injected into the buffer tank body from the injection pipe through a compression pump and condensed by a cooling block cooled by a cold water pipe. After the turpentine in the gas is condensed, it falls to the bottom of the buffer tank body and is collected through an oil outlet pipe, while the gas is discharged from the vacuum pipe at the upper end, thereby achieving the purpose of facilitating and rapid extraction.

[0026] In this embodiment, the device is used to extract turpentine from rosin. During extraction, the external vacuum pump is started to form a negative pressure inside the buffer tank body 1, and the gas generated by the combustion of rosin is injected into the buffer tank body 1 from the injection pipe 3 through the compression pump, and is condensed by the cooling block 4 cooled by the cold water pipe 6. After the turpentine in the gas is condensed, it falls to the bottom of the buffer tank body 1 and is collected through the oil outlet pipe 13, and the gas is discharged from the vacuum pipe 2 at the upper end, thereby achieving the purpose of facilitating rapid extraction.

[0027] like Figure 3 and Figure 4As shown, a condensing mechanism is provided at the middle part of the inner side of the buffer tank body 1, and an anti-blocking mechanism is provided at the upper end of the buffer tank body 1 near the condensing mechanism.

[0028] In this embodiment, when the compression pump injects gas into the buffer tank body 1 from the injection pipe 3, since the air pressure at the lower end of the cooling block 4 is greater than the air pressure at the upper end, the sleeve rod 9 is lifted by the entering gas until the sleeve rod 9 withdraws from the upper end of the cooling groove 7 and compresses the spring 11. When the extraction is completed, the external gas is reversely injected into the buffer tank body 1 from the vacuum tube 2, and the compressed spring 11 rebounds to control the sleeve rod 9 to be inserted into the cooling groove 7 from top to bottom, and the oil film formed in the cooling groove 7 is discharged from the bottom, thereby avoiding blockage.

[0029] Working principle: This device is used to extract turpentine from rosin. During extraction, the external vacuum pump is started to form a negative pressure inside the buffer tank body 1, and the gas generated by the combustion of rosin is injected into the buffer tank body 1 from the injection pipe 3 through the compression pump, and is condensed by the cooling block 4 cooled by the cold water pipe 6. After the turpentine in the gas is condensed, it falls to the bottom of the buffer tank body 1 and is collected through the oil outlet pipe 13, and the gas is discharged from the vacuum pipe 2 at the upper end. When the compression pump injects the gas into the buffer tank body 1 from the injection pipe 3, since the air pressure at the lower end of the cooling block 4 is greater than the air pressure at the upper end, the sleeve rod 9 is lifted by the entering gas until the sleeve rod 9 withdraws from the upper end of the cooling groove 7 and compresses the spring 11. When the extraction is completed, the external gas is reversely injected into the buffer tank body 1 from the vacuum pipe 2, and the compressed spring 11 rebounds to control the sleeve rod 9 to insert into the cooling groove 7 from top to bottom, and discharge the oil film formed in the cooling groove 7 from the bottom.
