Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and specifically relates to a sand washing machine. Background Art

[0002] Spiral sand washing machine is used in construction sites, gravel plants, prefabrication plants and hydropower sites where a large amount of sand and gravel is needed for desludging and screening operations. It can also be used for ore sorting operations. Spiral sand washing machine can effectively process sand and gravel within 0-30mm, wash away the mud and ash on the sand and gravel, and screen the sand and gravel with mud into clean sand and gravel. After a long time of sand washing, there will be a lot of mud or smaller sand and gravel in the water of the sand washing box.

[0003] When the spiral sand washing machine is working, the material enters the shell, then water is injected into the shell, and then the spiral conveying teeth rotate to carry out the sand washing operation.

[0004] However, when the spiral conveying teeth rotate, the material is mixed with water. At this time, due to the specific gravity, impurities and floating objects float in the upper part of the water, and sand is located in the lower part of the water. If the impurities are not removed at this time, these impurities and floating objects will be mixed in the sand, resulting in reduced quality of the sand. For example, a sand washing machine capable of cleaning floating objects as described in authorization number CN218308481U drives the threaded rod to rotate through a motor, and the threaded rod drives the half nut to rise, and the half nut can drive the filter screen to rise, so that the filter screen can take out the suspended matter, thereby removing the suspended matter; however, when removing the impurities and floating objects on the filter screen, it is done manually, which is time-consuming and labor-intensive.

[0005] To this end, we have proposed a sand washing machine that can separate floating objects from the water in the sand washing machine, and can automatically remove them without accumulation. It does not require manpower to remove, thus saving time and effort. Utility Model Content

[0006] The purpose of the utility model is to provide a sand washing machine, which can separate the floating objects from the water in the sand washing machine, and can automatically remove them without accumulation, and does not require manpower to remove, thereby achieving the effect of saving time and labor.

[0007] The technical solutions adopted in this utility are as follows:

[0008] A sand washing machine comprises a spiral sand washing machine body, wherein the spiral sand washing machine body comprises an inclined shell and two spiral sand washing assemblies arranged inside the shell;

[0009] An inclined through groove is provided on one side of the shell, and two fixing frames are provided on the top of the shell, rotating components are provided on the two fixing frames, two limiting plates and a rotating cylinder are provided on the rotating component, the rotating cylinder is provided between the two limiting plates, and a plurality of inclined filter plates are provided in an array outside the rotating cylinder, and an impurity removal area is formed between every two filter plates.

[0010] A material guide plate connected to the inner wall of the shell is arranged below the through slot, and the filter plate is fitted with the material guide plate when rotating.

[0011] Furthermore, a collecting shell is provided on one side of the shell.

[0012] Furthermore, the diameters of the two limiting plates are larger than the diameter of the rotating cylinder.

[0013] Furthermore, the rotating assembly includes a rotating shaft arranged between the two fixing frames, the limiting plate and the rotating cylinder are sleeved on the rotating shaft, and the rotating shaft is driven by a first motor arranged on one of the fixing frames.

[0014] Furthermore, the spiral sand washing assembly includes a driving motor arranged on the shell, a rotating shaft is installed at the output end of the driving motor, an end of the rotating shaft away from the driving motor passes through the shell, and a spiral conveying tooth is arranged on the rotating shaft.

[0015] Furthermore, the material guide plate is provided with a smooth surface.

[0016] The technical effects achieved by this utility model are:

[0017] When the assembly is rotated, the two limit plates and the rotating drum rotate. When the rotating drum rotates to the inside of the shell, because the filter plate is set at an angle, impurities and floating objects will enter the impurity removal area for carrying. The filter net allows the water to fall into the shell again for use. When it rotates to Figure 2 In the state shown, impurities and floating objects fall on the guide plate due to the tilting effect, and then flow out of the outside through the through slot. The device can separate the floating objects from the water in the sand washing machine, and can automatically remove them without accumulation, without manual removal, thus saving time and effort.

[0025] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0026] like Figure 1-5 As shown, the technical solution adopted by the present invention is as follows: a sand washing machine, comprising a spiral sand washing machine body 1, the spiral sand washing machine body 1 comprises an inclined shell 2 and two spiral sand washing components arranged inside the shell 2;

[0027] An inclined through slot 3 is provided on one side of the shell 2, and two fixing frames 4 are provided on the top of the shell 2, a rotating assembly is provided on the two fixing frames 4, two limiting plates 5 and a rotating cylinder 6 are provided on the rotating assembly, a rotating cylinder 6 is provided between the two limiting plates 5, and a plurality of inclined filter plates 7 are provided in an array outside the rotating cylinder 6, and an impurity removal area 8 is formed between every two filter plates 7.

[0028] A material guide plate 9 connected to the inner wall of the shell 2 is arranged below the through groove 3 , and the material guide plate 9 is in contact with the filter plate 7 .

[0029] Its working principle is: first, the material is allowed to enter the shell 2, and then water is injected into the shell 2. Because the shell 2 is tilted, the water and the material are located on the left side of the shell 2 due to gravity. At this time, the material is cleaned by the spiral sand washing component. Due to the specific gravity, the cleaned impurities and floating objects float in the upper half of the water, and the sand is located in the lower half of the water. If the impurities are not removed at this time, these impurities and floating objects will be mixed in the sand, resulting in a decrease in the quality of the sand. For this reason, people can make the floating objects be discharged with the water flow by opening an overflow port (because the opening opened on the shell 2 will not be too large, otherwise the sand washing effect will be poor). However, if a large floating object is encountered, the overflow port will be blocked. The utility model rotates the two limit plates 5 and the rotating drum 6 when the rotating assembly is rotated. When the rotating drum 6 rotates to the inside of the shell 2, because the filter plate 7 is tilted, the impurities and floating objects will enter the impurity removal area 8 for carrying, and the filter screen will make the water fall into the shell 2 again for use. When it is rotated to Figure 2 In the state shown, impurities and floating objects fall on the guide plate 9 due to the tilting effect, and then flow out of the outside through the through groove 3. The device can separate the floating objects from the water in the sand washing machine, and can automatically remove them without accumulation, without manpower removal, thus saving time and effort.

[0030] The opening of the through slot 3 can be large or small, which can be determined based on daily observations and the properties of floating materials.

[0031] At the same time, a collecting shell 10 is provided on one side of the shell 2, and the impurities and floating objects are collected by the collecting shell 10 for subsequent processing.

[0032] The diameter of the two limiting plates 5 is larger than the diameter of the rotating drum 6, so that when impurities and floating objects enter, they will not slide out from both sides.

[0033] It should be noted that the rotating drum 6 will not interfere with the spiral sand washing assembly when rotating, and a height adjustment assembly can be provided, such as Figure 5 As shown, the height adjustment assembly includes a threaded rod arranged on the shell 2, a threaded sleeve is sleeved on the threaded rod, and one side of the threaded sleeve is connected to the fixing frame 4, so that the height can be adjusted. Because the threaded rod and the threaded sleeve belong to the prior art, they are not described in detail here.

[0034] like Figure 4 As shown, the rotating assembly includes a rotating shaft 11 arranged between two fixed frames 4, a limiting plate 5 and a rotating cylinder 6 are sleeved on the rotating shaft 11, and the rotating shaft 11 is driven by a first motor 12 arranged on one of the fixed frames 4. The first motor 12 drives the rotating shaft 11 to rotate the limiting plate 5 and the rotating cylinder 6, thereby removing impurities and floating objects.

[0035] The first motor 12 is a DC speed regulating motor, which has the characteristics of excellent speed regulating performance and simple maintenance.

[0036] like Figure 3 As shown, the spiral sand washing assembly includes a driving motor 13 arranged on a housing 2, a rotating shaft is installed at the output end of the driving motor 13, an end of the rotating shaft away from the driving motor 13 passes through the housing 2, and a spiral conveying tooth 14 is arranged on the rotating shaft.

[0037] The driving motor 13 drives the rotating shaft to rotate the spiral conveying teeth 14, thereby cleaning the materials and completing the sand washing operation.

[0038] The guide plate 9 is provided with a smooth surface, through which impurities and floating objects can be prevented from adhering to each other and can be quickly guided out.

[0039] The working principle of the utility model is as follows: firstly, the material is allowed to enter the interior of the shell 2, and then water is injected into the interior of the shell 2. Because the shell 2 is tilted, the water and the material are located on the left side of the shell 2 due to gravity. At this time, the material is cleaned by the spiral sand washing component. Due to the specific gravity, the cleaned impurities and floating objects float in the upper half of the water, and the sand is located in the lower half of the water. At this time, if the impurities are not removed, these impurities and floating objects will be mixed in the sand, resulting in a decrease in the quality of the sand. For this reason, people can make the floating objects be discharged with the water flow by opening an overflow port (because the opening opened on the shell 2 will not be too large, otherwise the effect of sand washing will be poor). However, if a large floating object is encountered, the overflow port will be blocked. The utility model rotates the two limit plates 5 and the rotating drum 6 when the rotating assembly is rotated. When the rotating drum 6 rotates to the interior of the shell 2, because the filter plate 7 is tilted, the impurities and floating objects will enter the impurity removal area 8 for carrying, and the filter screen will make the water fall into the interior of the shell 2 again for use. When it is rotated to Figure 2 In the state shown, impurities and floating objects fall on the guide plate 9 due to the tilting effect, and then flow out of the outside through the through groove 3. The device can separate the floating objects from the water in the sand washing machine, and can automatically remove them without accumulation, without manpower removal, thus saving time and effort.

[0040] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
