Description

Technical Field

[0001] The present application relates to the technical field of hydrocyclones, and in particular to an adjustable hydrocyclone. Background Art

[0002] A hydrocyclone is a classification device that uses centrifugal force to accelerate the settling of mineral particles. The size of the hydrocyclone's grit nozzle has a direct impact on the cyclone's separation efficiency and processing capacity. A larger nozzle reduces the flow rate of the processed liquid, allowing settled particles to settle more easily and concentrate in the nozzle, thereby improving separation efficiency. However, an oversized nozzle causes increased liquid loss, compromising separation efficiency. The size of the nozzle also affects the cyclone's processing capacity. A smaller nozzle results in finer discharged solid particles. These fine solid particles are easily carried over to the next device, potentially affecting subsequent processing. An oversized nozzle, on the other hand, can reduce processing capacity.

[0003] However, during the production process, grinding and classifying different ore bodies is often necessary. Due to the different properties of the ore, the size of the grit nozzle needs to be adjusted to control the classification of the slurry. However, the traditional method of replacing the grit nozzle is relatively complicated, which seriously affects the efficiency of grinding and mineral processing. Utility Model Content

[0004] In order to solve or partially solve the problems existing in the related art, the present application provides an adjustable hydrocyclone, which aims to solve the problem that the replacement method of the traditional sand settling nozzle is relatively complicated.

[0005] The present application provides an adjustable hydrocyclone, comprising a hydrocyclone cylinder, an adjustable sand settling nozzle group and a sand settling port;

[0006] The adjustable sand settling nozzle group is installed at the lower end of the hydrocyclone cylinder, and the sand settling port is installed at the bottom of the adjustable sand settling nozzle group;

[0007] The adjustable sand trap group consists of one or more sand trap splicing sections, which are spliced ​​into a smooth slope. The sand trap splicing section is a hollow frustum.

[0008] An external threaded sleeve is provided on the top of the sand settling nozzle splicing section, which is used to connect the hydrocyclone cylinder of the sand settling nozzle splicing section or the upper sand settling nozzle splicing section. An internal nut cavity is provided on the inner side of the bottom of the sand settling nozzle splicing section, which is used to fix the sand settling nozzle splicing section or sand settling port below.

[0009] Optionally, in some embodiments, the adjustable sand trap assembly is composed of one or more sand trap splicing sections, including:

[0010] The external threaded sleeve at the upper end of the lower sand setting nozzle splicing section is installed in the inner nut cavity of the upper sand setting nozzle splicing section.

[0011] Optionally, in some embodiments, the outer surface of the externally threaded sleeve is provided with threads, and the inner side of the inner nut cavity is provided with threads matching the externally threaded sleeve.

[0012] Optionally, in some embodiments, the cone angle of the sand trap joint section is 15-20 degrees.

[0013] Optionally, in some embodiments, the sand trap splicing section is made of plastic hard rubber material.

[0014] The technical solution provided by this application may have the following beneficial effects:

[0015] By adding or removing the sand nozzle splicing section at the bottom of the adjustable sand nozzle group, the size of the sand nozzle can be adjusted, thereby controlling the classification of the slurry and adjusting the sand ratio. This prevents the loss of useful minerals caused by the mismatch of the sand nozzle diameter when the grinding particle size is unstable, thereby improving the grinding and mineral processing efficiency.

[0025] During production, grinding and classifying different ore bodies is often necessary. Different ore properties necessitate adjusting the size of the grit nozzle to control the slurry classification. However, traditional methods of replacing grit nozzles are complex, significantly impacting grinding and beneficiation efficiency.

[0026] In response to the above problems, an embodiment of the present application provides an adjustable hydrocyclone, which can adjust the size of the sand nozzle by adding or removing the sand nozzle splicing section at the bottom of the adjustable sand nozzle group, thereby controlling the classification of the slurry and adjusting the sand setting ratio, preventing the classification from being uncontrollable due to the mismatch of the sand nozzle diameter when the grinding particle size is unstable, resulting in the loss of useful minerals, thereby improving the grinding and mineral processing efficiency.

[0027] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0028] Figure 1 It is a schematic structural diagram of an adjustable hydrocyclone shown in an embodiment of the present application.

[0029] See also Figure 1 , an adjustable hydrocyclone, comprising:

[0030] Hydrocyclone cylinder 1, adjustable sand settling nozzle assembly 2, sand settling nozzle splicing section 3, external threaded sleeve 4, internal nut cavity 5 and sand settling port 6;

[0031] The adjustable grit nozzle assembly 2 is mounted at the lower end of the hydrocyclone cylinder 1. It consists of one or more grit nozzle sections 3, each of which is a hollow, truncated cone made of a plastic hard rubber material. An externally threaded sleeve 4 is installed at the top of the grit nozzle section 3. This sleeve 4 has threads on its outer surface, connecting the grit nozzle section 3 to the hydrocyclone cylinder 1 or the upper grit nozzle section 3. An internal nut cavity 5 is located inside the bottom of the grit nozzle section 3. This cavity is threaded to match the externally threaded sleeve 4 and secure the grit nozzle section 3 or the grit port 6 below.

[0032] The taper angle of the sand trap splicing section 3 is 15, 16, 17, 18, 19, or 20 degrees. The externally threaded sleeve 4 of the lower sand trap splicing section 3 is screwed into the internal nut cavity 5 of the upper sand trap splicing section 3. When assembled, multiple sand trap splicing sections 3 are connected to form a smooth slope. The splicing sections 3 are tightly connected and leak-proof. The sand trap 6 is installed in the internal nut cavity 5 at the bottom of the upper adjustable sand trap assembly 2.

[0033] When used in this application, the adjustable sand settling nozzle group 2 is connected to the bottom of the hydrocyclone cylinder 1 by threading, and the sand settling nozzle splicing sections 3 are connected by threading to form the adjustable sand settling nozzle group 2. The external threaded sleeve 4 of the lower sand settling nozzle splicing section 3 is screwed into the internal nut cavity 5 of the upper sand settling nozzle splicing section 3. The size of the sand settling port 6 is adjusted by adding or removing the lowest sand settling nozzle splicing section 3. Specifically, according to production needs, when it is necessary to increase the sand settling port, the lowest sand settling nozzle splicing section 3 is rotated, the sand settling nozzle splicing section 4 is removed, and the sand settling port 6 is replaced and adjusted. At this time, the diameter of the sand settling port becomes the diameter of the sand settling nozzle splicing section 3 remaining at the bottom after removal, and the sand settling port is increased. When it is necessary to reduce the sand settling port, a smaller sand settling nozzle splicing section 3 is reinstalled and rotated to be installed on the lowest sand settling nozzle splicing section 3. At this time, the diameter of the sand settling port is the lower diameter of the newly installed sand settling nozzle splicing section 3, and the sand settling port is reduced.

[0034] The embodiments of the present application have been described above. The above description is illustrative and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or improvements to the technology in the market, or to enable other persons skilled in the art to understand the embodiments disclosed herein.
