Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a sandblasting machine, in particular to a sandblasting cyclone separator and sandblasting equipment. Background Art

[0002] A large amount of dust will be generated during the sandblasting process. The sand and dust need to be continuously separated to effectively recycle the sand to achieve continuous cyclic sandblasting operations. If the dust mixed in the sand is not separated thoroughly, it will easily affect the qualified rate of the sandblasted products.

[0003] The existing separator is only provided with a simple conical cover for single sand material sedimentation and separation. However, the sand material is easily affected by the airflow during the sedimentation process, resulting in secondary rise, so that part of the sand material is discharged with the airflow, resulting in a reduced probability of sand material recovery, poor separation effect, and further increase in sandblasting.

[0004] For example, Chinese patent document 202111597610.0 discloses a cyclone separator, including a shell, the upper part of which is a spiral part; a mixed feed port is provided at the top of the shell for feeding; an exhaust pipe is provided at the top of the shell, one end of which is connected to the inner cavity of the shell, and the other end is used to connect a negative pressure device; an air supply pipe is provided in the exhaust pipe, one end of which is connected to the inner cavity of the shell, and the other end is connected to the atmosphere; a diffuser is provided at the bottom of the air supply pipe, and the diffuser is wrapped in the peripheral direction of the air supply pipe and expands outward. The cyclone separator is provided with an air supply pipe inside, and a diffuser is provided at the bottom of the air supply pipe. After the air flow in the supplementary pipe is guided by the diffuser, an upward air flow will be formed, which can continuously impact the mixed material falling in the shell, so that the lighter unqualified abrasive particles and dust and other debris are separated from the qualified abrasive, thereby improving the separation effect and separation efficiency of the cyclone separator.

[0005] In the above technical solution, a diffuser plate is used to guide the airflow to impact the falling mixed material and separate the debris and abrasive again. However, the diffuser plate has a conical structure, which is too simple in guiding the airflow and cannot provide centrifugal force, resulting in poor separation effect. Utility Model Content

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] Embodiment 1

[0031] like Figures 1 to 3 As shown, the sandblasting cyclone separator comprises a cylindrical shell with a separation inner cavity, in which an air outlet cylinder 3, a diverter hood 4 and a spiral separator are arranged in sequence from top to bottom, an air inlet 1a is opened on the side wall of the upper part of the cylindrical shell, the inlet of the air inlet 1a is arranged to be aligned with the outer wall of the air outlet cylinder 3, an air outlet 1b is opened on the top surface of the cylindrical shell, the top opening of the air outlet cylinder 3 is connected to the air outlet 1b, the bottom opening of the air outlet cylinder 3 is connected to the separation inner cavity, a sand outlet 2a is opened at the bottom of the cylindrical shell, and the spiral separator is suspended directly above the sand outlet 2a.

[0032] The shell includes an upper cylindrical shell 1 and a lower conical shell 2. An air inlet 1a is arranged on the side wall of the cylindrical shell 1, and an air outlet 1b is arranged on the top wall of the cylindrical shell 1. The large diameter end of the conical shell 2 is integrally connected to the bottom of the cylindrical shell 1, and a sand outlet 2a is opened on the small diameter end of the conical shell 2. The wind flows from the air inlet 1a into the separation cavity of the shell, fills the separation cavity, enters from the bottom of the air outlet 3 and rises, and is finally discharged from the upward air outlet 1b.

[0033] like Figure 2 and 3 As shown, the air outlet 3 is a circular cylinder, and the air outlet 3 is located in the cylindrical shell 1, and the bottom of the air outlet 3 exceeds the lower edge of the air inlet 1a. The length of the air outlet 3 is controlled so that it does not exceed the length of the cylindrical shell 1, and completely blocks the air inlet 1a, so that after the wind flow enters, the sand material carried in the wind flow contacts the outer wall of the air outlet 3. The top wall of the cylindrical shell 1 is provided with an annular plate, and the opening in the center of the annular plate is the air outlet 1b, and the top opening of the air outlet 3 is sealed with the opening.

[0034] like Figure 2 and 3 As shown, the diverter cover 4 is a conical cover body, the top angle of the conical cover body is upwardly aligned with the center point of the air outlet cylinder 3, the large diameter opening of the conical cover body is downwardly facing, the diameter of the large diameter opening of the conical cover body is larger than the bottom opening diameter of the air outlet cylinder 3, and a circulation annular gap is formed between the conical cover body and the bottom opening of the air outlet cylinder 3. After the sand material in the wind flow contacts the diverter cover 4, it slides down along the inclined surface of the cover body, and the wind flow carries the dust and continues to rise through the circulation annular gap and enters the air outlet cylinder 3.

[0035] The flow divider 4 is arranged in the cylindrical shell 1, and a gap is left between the edge of the large diameter opening of the flow divider 4 and the inner wall of the cylindrical shell 1. The gap provides a falling space for the sand material and an ascending space for the airflow to carry the dust.

[0036] like Figure 2 and3 As shown, the spiral separator includes a shaft rod 5, the top end of the shaft rod 5 is fixedly connected to a T-frame, the vertical rod of the T-frame passes through the top corner of the diverter hood 4 and connects to the shaft rod 5, the position of the diverter hood 4 is fixed by the vertical rod of the T-frame, the cross bar of the T-frame is fixed on the bottom surface of the annular plate, the shaft rod 5 is arranged on the central axis of the cylinder shell, and the outer periphery of the shaft rod 5 surrounds the spiral blade 6. The suspension state of the diverter hood 4 and the spiral blade 6 is realized by the T-frame and the shaft rod 5, the spiral blade 6 is fixed by the shaft rod 5, and the spiral guide structure is formed by the spiral blade 6.

[0037] The upper part of the spiral blade 6 is located in the cylindrical shell 1 , and the lower part of the spiral blade 6 extends into the conical shell 2 .

[0038] Embodiment 2

[0039] Based on the first embodiment, the differences of this embodiment are as follows:

[0040] like Figure 4 As shown, a sandblasting device comprises the above-mentioned sandblasting cyclone separator.

[0041] The sandblasting equipment comprises a machine platform 7, on which a cylinder shell is fixed by a fixing frame, and a sand outlet 2a of the cylinder shell is connected to a material storage box inside the machine platform 7 by a material delivery pipe.

[0042] The operation process of this sandblasting equipment:

[0043] The wind flow carrying sand and dust enters from the air inlet 1a, and contacts the outer wall of the air outlet 3 first, so that the wind flow carrying sand and dust is blocked by the circular cylinder, wherein the sand will sink according to its own weight, and at the same time, the wind flow carrying dust passes through the circulation annular gap above the conical cover body and enters the air outlet 3, until it is discharged from the air outlet 1b.

[0044] If the sunken sand material rises again and wants to enter the air outlet 3, the spiral blades 6 form a spiral blocking structure for the sand material. When rising, the sand material rotates around the spiral blades 6 in the fluid, thereby generating centrifugal force, so that the sand material falls again by its own gravity after contacting the spiral blades 6, which will enable the sand material to be separated more fully.

[0045] The sand outlet 2a at the bottom of the shell is connected to the material storage box inside the machine 7, so that the separated sand material can directly flow into the machine 7 for recycling.
