Description

Technical Field

[0001] The utility model relates to the technical field of oil processing equipment, in particular to a crystal growing tank for oil processing. Background Art

[0002] The existing technology of oil crystallization and crystal growing tanks are of two types: vertical and horizontal. Both are equipped with a mechanical stirring shaft and its stirring blades in the center of the tank body. A heat exchange and cooling coil is provided between the tank body and the stirring blades. The low-temperature refrigerant liquid flows through the tank jacket and the coils. The oil in the tank is forced to flow under stirring, thereby achieving heat exchange and cooling. Crystals are precipitated during the cooling process, and the precipitated fine crystals are then formed into coarse agglomerates. The oil is forced to flow under mechanical stirring to complete the crystallization and crystal growing process. During the use of the existing technology of oil crystallization and crystal growing tanks, the stirring of the mechanical stirring blades causes the forced flow of the oil in the tank to The oil is uneven because the linear velocity of the oil flowing near the center is low, while the linear velocity of the oil flowing far from the center is high. In addition, the discontinuous distribution of the stirring blades also causes obvious differences in the flow velocity of the oil and grease that is touched and not touched. This will cause the oil and grease in the center of the tank to exchange less heat and have a lower flow rate, while the oil and grease in the tank wall area will exchange more heat and have a higher flow rate, resulting in poor crystallization and crystal growth effects of the oil and grease. At the same time, since the stirring shaft and its stirring blades occupy the center of the tank, the refrigerant coil cannot be distributed in the center. The coil is located in a narrow position of the tank shell and is small in number, resulting in uneven cooling of the oil and grease, which leads to poor crystallization and crystal growth effects. Utility Model Content

[0003] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology, and to propose a crystal growing tank for oil processing.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] The control cabinet that is provided with the control cabinet is provided with the control cabinet, and the control cabinet is provided with the control cabinet.

[0006] Preferably, the outer wall of the stirring rod is annular and has three stirring blades equidistantly arranged thereon, and the outer walls of the stirring blades are in close contact with the inner wall of the inner cylinder.

[0007] Preferably, a discharge port is provided at the bottom of the inner cylinder, and the discharge plate is matched with the discharge port, and the discharge plate is just embedded in the discharge port, and the discharge plate rises and falls vertically in the discharge port.

[0008] Preferably, hollow channels are provided at the left and right ends of the interior of the stirring rod, and the pipes at the discharge end and the inlet end of the circulating pump are connected to the right side of the interior of the stirring rod and the cooling water tank through the right connecting ring, and the left side of the interior of the stirring rod is connected to the interior of the cooling water tank through the left connecting ring and the pipe.

[0009] Preferably, a hollow cooling channel is provided inside the stirring blade, and the left and right ends of the cooling channel are respectively connected to the hollow channels at the left and right ends inside the stirring rod.

[0011] 1. During the crystallization process of grease, the servo motor drives the stirring blade to circulate and stir the grease through the stirring rod. Since the outer wall of the stirring blade is close to the inner cylinder, the grease will continue to roll and crystallize in the inner cylinder. When the crystallized grease sticks to the inner wall of the inner cylinder, the stirring blade will scrape off the crystallized grease. When the discharge plate moves down from the inner cylinder, the grease will fall from the inner cylinder, realizing the rapid collection of the grease.

[0012] 2. During the crystallization of oil, the circulating pump draws the cooling water from the cooling water tank through the right connecting ring into the right side of the stirring rod, then into the inside of the stirring blade to cool it down, then into the left side of the stirring rod and into the left connecting ring, and flows back to the cooling water tank along the pipeline. In this way, the stirring blade is cooled down and the heat sink is used to dissipate heat from the inner cylinder, so that the oil can be quickly cooled and crystallized. The oil is cooled more evenly during the heat exchange process, which further improves the crystallization speed of the oil. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] Example 1, with reference to Figure 1-4 A crystallization tank for oil processing comprises a workbench 1 and a support frame 101. The support frames 101 are fixed to the left and right ends of the top of the workbench 1. The feature is that a circulation pump 102 and a cooling water tank 103 are fixed to the right and left sides of the front end of the workbench 1 respectively, a servo motor 104 is fixed to the left side of the support frame 101, and the servo motor 104 and the right connecting ring 204 are fixed to the left and right ends above the two support frames 101 respectively. The right side of the servo motor 104 is connected to a stirring rod 105 for horizontal rotation, and a stirring blade 1 is fixed to the outer wall of the stirring rod 105. 06. An outer cylinder 2 is fixed horizontally above the workbench 1. Hydraulic cylinders 201 are fixed vertically on the left and right ends of the bottom of the outer cylinder 2. A discharge plate 202 is fixed on the top of the push rods at the output ends of the two hydraulic cylinders 201. An inner cylinder 21 is fixed above the two support frames 101. A heat sink 203 is fixed on the outer wall of the inner cylinder 21. A left connecting ring 205 is fixed on the left side of the inner cylinder 21. Electric push rods 206 are fixed horizontally at the front and rear ends of the right side of the support frame 101. A sealing plate 207 is connected to the left side of the push rods at the output ends of the two electric push rods 206.

[0020] The outer wall of the stirring rod 105 is annular and has three stirring blades 106 equidistantly arranged thereon. The outer wall of the stirring blades 106 is in close contact with the inner wall of the inner cylinder 21.

[0021] The bottom of the inner cylinder 21 is provided with a discharge port, and the discharge plate 202 is matched with the discharge port. The discharge plate 202 is just embedded in the discharge port, and the discharge plate 202 rises and falls vertically in the discharge port;

[0022] During the crystallization process of the grease, the servo motor 104 drives the stirring blade 106 through the stirring rod 105 to circulate and stir the grease. Since the outer wall of the stirring blade 106 is in close contact with the inner cylinder, the grease will continue to roll and crystallize in the inner cylinder. When the crystallized grease sticks to the inner wall of the inner cylinder 21, the stirring blade 106 will scrape the crystallized grease off. Subsequently, the hydraulic cylinder 201 pulls the discharge plate 202 downward, and when it is opened, the grease will fall from the inner cylinder 21, thereby realizing rapid collection of the grease.

[0023] Hollow channels are provided on both the left and right ends of the stirring rod 105. The pipes at the discharge end and the liquid inlet end of the circulating pump 102 are connected to the right side of the stirring rod 105 and the cooling water tank 103 through the right connecting ring 204. The left side of the stirring rod 105 is connected to the interior of the cooling water tank 103 through the left connecting ring 205 and the pipe.

[0024] A hollow cooling channel is provided inside the stirring blade 106, and the left and right ends of the cooling channel are respectively connected to the hollow channels at the left and right ends of the stirring rod 105;

[0025] During the process of the stirring rod 105 driving the stirring blade 106 to rotate and stir and crystallize the oil, the circulating pump 102 draws the cooling water in the cooling water tank 103 into the right side of the interior of the stirring rod 105 through the right connecting ring 204, and then enters the interior of the stirring blade 106 to cool the stirring blade 106, and then enters the left side of the interior of the stirring rod 105 and enters the left connecting ring 205, and flows back to the cooling water tank 103 along the pipeline. In this cycle, the stirring blade 106 is cooled and cooled, and the oil in the inner cylinder 21 is quickly cooled and crystallized. The oil is cooled more evenly during the heat exchange process, which further improves the crystallization speed of the oil.

[0026] Example 2. Example 2 differs from Example 1 in that there is a certain distance between the outer wall of the inner cylinder 21 and the inner wall of the outer cylinder 2, the heat sink 203 is arranged between the outer wall of the inner cylinder 21 and the inner wall of the outer cylinder 2, and the internal horizontal opening of the heat sink 203 is provided with a heat dissipation port.

[0027] During the crystallization process, the heat of the inner cylinder 21 is transferred to the heat sink 203 and then dissipated into the air from the heat dissipation port on the top of the outer cylinder 2, thereby dissipating heat from the outer cylinder 2;

[0028] When the two electric push rods 206 pull the sealing plate 207 to move rightward, the right side of the inner cylinder 21 is opened, and the interior of the inner cylinder 21 can be cleaned from time to time.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
