Description

Technical Field

[0001] The invention relates to the technical field of screening, in particular to a raw material screening device for producing ceramic bottles. Background Art

[0002] The production of ceramic bottles requires a variety of raw materials, such as clay, quartz and feldspar, which need to be screened during the processing to ensure the quality and performance of the final product. Screening is to remove unsuitable particles, impurities or uneven materials to ensure the uniformity and plasticity of the raw materials.

[0003] Most of the existing screening equipment is a vibrating screener, which includes a vibration mechanism, a shell and a multi-layer screen. The top of the shell is a feed port, the bottom is a small particle discharge port, and the side is a large particle discharge port. The multi-layer screen is arranged in the shell and is arranged at intervals in the vertical direction. The vibration mechanism is arranged in the shell and connected to the multi-layer screen to make the multi-layer screen vibrate. When in use, the staff pours the material to be screened into the shell from the feed port, and the material falls on the screen. Under the action of the vibration mechanism, the large particle material remains on the screen, and the small particle material falls from the mesh of the screen. At this time, the large particle material is discharged from the large particle discharge port, and the small particle material is discharged from the small particle discharge port. However, the existing screening equipment has the following problems when in use: when the screen is in use, the material to be screened is mainly concentrated in the center of the screen, rather than being evenly dispersed on the screen, so the local wear of the screen is serious, and after long-term use, there is a risk of the screen wire breaking. Summary of the invention

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings). In the description of the present invention, it should be understood that the orientation or position relationship indicated by the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc. are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0038] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0039] like Figure 1-Figure 7As shown, a raw material screening device for ceramic bottle production includes a chassis 100 and a screening assembly 200. A screening chamber 110 is provided in the chassis 100. The upper and lower ends of the screening chamber 110 pass through the chassis 100. There are multiple screening assemblies 200, and the multiple screening assemblies 200 are arranged in the screening chamber 110 at equal intervals along the vertical direction. The screening assembly 200 includes a first drive shaft 210, a second drive shaft 220 and a conveyor mesh belt 230. The axes of the first drive shaft 210 and the second drive shaft 220 are horizontal and rotatably connected to the chassis 100. The first drive shaft 210 and the second drive shaft 220 can both rotate around their axes. The conveyor mesh belt 230 is transmission-connected to the first drive shaft 210, and the conveyor mesh belt 230 is transmission-connected to the second drive shaft 220. When in a non-working state, the conveyor mesh belt 2 30 is in a relaxed state as a whole. In the process of switching from a non-working state to a working state, the first drive shaft 210 rotates clockwise around its axis at a first rate, and the second drive shaft 220 rotates counterclockwise around its axis at a second rate, and the first rate is greater than the second rate. At this time, the conveyor mesh belt 230 is driven circumferentially by the first drive shaft 210 and the second drive shaft 220, and because the front end feed amount of the transmission mesh belt 230 is large and the rear end feed amount is small, the upper part of the conveyor mesh belt 230 gradually switches from a relaxed state to a tensioned state. After the upper part of the conveyor mesh belt 230 is in a tensioned state, the conveyor mesh belt 230 is in a working state, and the first drive shaft 210 and the second drive shaft 220 both rotate clockwise at a first rate to keep the upper part of the conveyor mesh belt 230 in a tensioned state.

[0040] When not in use, the conveyor mesh belt 230 is in a relaxed state to prevent the mesh of the conveyor mesh belt 230 from being stretched and broken due to long-term tension. When in use, the staff adjusts the upper part of the conveyor mesh belt 230 to a tensioned state to reduce the probability of mesh breakage of the conveyor mesh belt 230. The staff then starts the screening assembly 200 to rotate the first drive shaft 210 clockwise around its axis at a first rate, and the second drive shaft 220 rotates counterclockwise around its axis at a second rate. The first rate is greater than the second rate. At this time, the front end feed amount of the conveyor mesh belt 230 is large, and the rear end feed amount is small. Therefore, the upper part of the conveyor mesh belt 230 is gradually switched from a relaxed state to a tensioned state, and the conveyor mesh belt 230 After being in the tensioned state, the first drive shaft 210 and the second drive shaft 220 both rotate clockwise at a first speed. During this process, the upper part of the conveyor mesh belt 230 remains in a tensioned state. Next, the staff pours the material to be screened into the screening chamber 110 from the upper end opening of the screening chamber 110. Under the action of the material's own gravity, the material falls onto the conveyor mesh belt 230, and the small particle material passes through the mesh holes of the conveyor mesh belt 230, while the large particle material remains on the conveyor mesh belt 230. Due to the circumferential transmission of the conveyor mesh belt 230, the material on the conveyor mesh belt 230 is forced to roll, which can separate the large particle material from the small particle material, thereby completing the screening of the material.

[0041] It is understandable that, since the conveyor mesh belt 230 is circumferentially driven, the material to be screened is not in contact with only a part of the conveyor mesh belt 230, so the mesh body of the conveyor mesh belt 230 is not prone to serious local wear, and after long-term use, the conveyor mesh belt 230 is not prone to mesh wire breakage. It is also understandable that the reason why the upper part of the conveyor mesh belt 230 is tensioned is to prevent the conveyor mesh belt 230 from being concave due to the gravity of the material, thereby causing the material to be unable to be screened normally.

[0042] It should also be noted that in order to enhance the vibration force exerted on the material on the conveyor belt 230, a vibration source, such as a vibration motor, can also be arranged inside the screening chamber 110, so that the vibration force exerted on the material falling onto the conveyor belt 230 is stronger, so as to facilitate the full separation of large particles and small particles.

[0043] It should also be added that in order to prevent material accumulation, the material should be screened step by step. Specifically, the apertures of the multiple conveyor belts 230 from top to bottom in the vertical direction should be gradually reduced. This can disperse the material to each conveyor belt 230 and avoid material accumulation on one conveyor belt 230, which would make it difficult to separate large and small particles of material.

[0044] It should also be noted that if Figure 4 As shown, a plurality of upper limit rings 310 are disposed in the screening chamber 110 , and the plurality of upper limit rings 310 correspond one-to-one to the plurality of conveyor mesh belts 230 , and the upper limit rings 310 are in surface contact with the upper outer side surfaces of the conveyor mesh belts 230 .

[0045] The upper limit ring 310 is provided and is in surface contact with the upper outer side surface of the conveyor mesh belt 230 in order to limit the material to be screened, so that the material to be screened is limited in the inner annular area of ​​the upper limit ring 310 to prevent the material from falling with the circumferential transmission of the conveyor mesh belt 230.

[0046] It should be further explained that, in order to separate the large particles in the inner area of ​​the upper limit ring 310 from the upper limit ring 310, specifically, Figure 6 As shown, a notch 311 is provided on the upper limit ring 310 , and a plurality of large particle discharge ports 710 are provided on the outer side of the chassis 100 . The plurality of large particle discharge ports 710 correspond one-to-one to the plurality of conveyor belts 230 , and the notch 311 faces the large particle discharge ports 710 .

[0047] When the large-particle material in the inner area of ​​the upper limit ring 310 rolls to the position of the notch 311 , the large-particle material further rolls from the notch 311 to the large-particle discharge port 710 , so that the large-particle material is discharged from the chassis 100 through the large-particle discharge port 710 .

[0048] In a further embodiment, Figure 1 , Figure 4 and Figure 5 As shown, the raw material screening equipment for ceramic bottle production also includes an extrusion assembly 400. There are multiple groups of extrusion assemblies 400, each group has two, and the multiple groups of extrusion assemblies 400 correspond one by one to the multiple conveyor belts 230. The extrusion assembly 400 is located at the lower part of the conveyor belt 230. The extrusion assembly 400 can reciprocally extrude the upper part of the corresponding conveyor belt 230 so that the upper and lower parts of the conveyor belt 230 collide reciprocatingly. The two extrusion assemblies 400 in the same group are respectively arranged on the side close to the first drive shaft 210 and the side close to the second drive shaft 220.

[0049] During the process of the conveyor mesh belt 230 screening the material, the extrusion assembly 400 reciprocatingly squeezes the lower part of the conveyor mesh belt 230 corresponding thereto, thereby pushing the lower part of the conveyor mesh belt 230 to reciprocately approach the upper part of the conveyor mesh belt 230. As a result, the upper and lower parts of the conveyor mesh belt 230 are reciprocatingly squeezed and collided, so that the upper part of the conveyor mesh belt 230 is subjected to a greater vibration force, thereby preventing the mesh holes on the conveyor mesh belt 230 from being blocked by the material and affecting the screening of the material.

[0050] In a further embodiment, Figure 1 , Figure 4 and Figure 5 As shown, the extrusion assembly 400 includes a third motor 440, a swing arm 420 and a swing rod 410. The third motor 440 is arranged outside the chassis 100, one end of the swing arm 420 is arranged on the output shaft of the third motor 440, and the other end of the swing arm 420 is fixedly connected to the swing rod 410. Two guide waist grooves 430 are opened on the chassis 100, and the two guide waist grooves 430 are located in the middle area of ​​the first drive shaft 210 and the second drive shaft 220. One of the guide waist grooves 430 is concentric with the first drive shaft 210, and the other guide waist groove 430 is concentric with the second drive shaft 220. The swing rod 410 corresponding to the extrusion assembly 400 close to the first drive shaft 210 is slidably connected in the guide waist groove 430 concentric with the first drive shaft 210, and the swing rod 410 corresponding to the extrusion assembly 400 close to the second drive shaft 220 is slidably connected in the guide waist groove 430 concentric with the second drive shaft 220.

[0051] Specifically, during the process of the conveyor mesh belt 230 screening the materials, the staff starts the third motor 440, so that the output shaft of the third motor 440 alternately switches between clockwise rotation of a preset angle and counterclockwise rotation of a preset angle. When the output shaft of the third motor 440 drives the swing arm 420 to rotate upward, the swing arm 420 drives the swing rod 410 to swing upward along the guide waist groove 430, and the swing rod 410 pushes the lower part of the conveyor mesh belt 230 to move upward, so that the lower part of the conveyor mesh belt 230 and The upper parts approach and collide with each other. When the swing arm 410 abuts against the upper bottom of the guide waist groove 430, the output shaft of the third motor 440 rotates in the opposite direction by a preset angle. At this time, the output shaft of the third motor 440 drives the swing arm 420 to rotate downward so that the swing arm 410 abuts against the lower bottom of the guide waist groove 430, thereby causing the swing arm 410 to push the lower part of the conveyor mesh belt 230 and the upper part of the conveyor mesh belt 230 to reciprocately squeeze and collide, thereby preventing the mesh holes on the conveyor mesh belt 230 from being blocked and affecting the screening of materials.

[0052] In a further embodiment, Figure 5 As shown, a plurality of lower limit rings 320 are slidably provided in the screening chamber 110, and the plurality of lower limit rings 320 correspond one to one with the plurality of conveyor mesh belts 230. The lower limit rings 320 are located on the inner side of the conveyor mesh belt 230, and the lower limit rings 320 are in surface contact with the lower inner side surface of the conveyor mesh belt 230. A sliding guide rod 520 is provided on the side of the lower limit ring 320 close to the first drive shaft 210 and the side close to the second drive shaft 220. A linear guide groove 510 is correspondingly opened in the screening chamber 110, and the linear guide groove 510 extends in the vertical direction. The sliding guide rod 520 is slidably connected in the linear guide groove 510.

[0053] When the lower part of the conveyor mesh belt 230 is pushed by the rocker arm 410 and moves upward, the conveyor mesh belt 230 applies an upward force to the lower limit ring 320, so that the lower limit ring 320 moves upward along the linear guide groove 510 under the guidance of the linear guide groove 510 and the sliding guide rod 520. During this process, the lower limit ring 320 maintains surface contact with the lower inner side surface of the conveyor mesh belt 230, thereby limiting the material that falls onto the lower inner side surface of the conveyor mesh belt 230 and preventing the material from rolling down from the conveying end of the conveyor mesh belt 230.

[0054] It should also be noted that in order to discharge the large particle material that falls on the inner side of the lower limit ring 320, the lower limit ring 320 should also be provided with a notch 311, and the notch 311 on the lower limit ring 320 corresponds to the notch 311 on the upper limit ring 310. Similarly, a large particle discharge port 710 is also provided on the outside of the chassis 100 and at a position corresponding to the notch 311 on the lower limit ring 320. The large particle discharge port 710 is used to discharge the large particle material flowing out of the notch 311 of the lower limit ring 320 out of the chassis 100.

[0055] In a further embodiment, Figure 4 and Figure 5 As shown, a plurality of groups of pressure sensors 610 are arranged in the screening chamber 110, and the plurality of groups of pressure sensors 610 correspond one-to-one to the plurality of conveyor mesh belts 230. Each group of pressure sensors 610 is located on a side of the conveyor mesh belt 230 close to the first driving shaft 210. There are a plurality of pressure sensors 610 in each group, and the plurality of pressure sensors 610 in each group are arranged in a straight line along the width direction of the conveyor mesh belt 230. The sensing end of the pressure sensor 610 is in contact with the upper outer side surface of the conveyor mesh belt 230. In the initial state, there is a preset pressure between the pressure sensor 610 and the conveyor mesh belt 230.

[0056] A pressure sensor 610 is provided to detect whether there are damaged points on the surface of the conveyor mesh belt 230 (i.e., whether there is a mesh wire that is broken due to excessive tension). If the pressure sensor 610 detects that the pressure value is zero when a certain point of the conveyor mesh belt 230 moves below it, it means that the mesh wire of the conveyor mesh belt 230 at this location is broken, and then this location of the conveyor mesh belt 230 can no longer be used for material screening. Next, the first drive shaft 210 and the second drive shaft 220 are switched from clockwise rotation at the same speed to reciprocating switching between clockwise rotation at a preset angle and counterclockwise rotation at a preset angle, thereby preventing the damaged point of the conveyor mesh belt 230 from moving to the inner area of ​​the upper limit ring 310.

[0057] In a further embodiment, Figure 1 As shown, a first motor 810 and a second motor 820 are disposed outside the chassis 100 . The first motor 810 is used to drive the first drive shaft 210 to rotate, and the second motor 820 is used to drive the second drive shaft 220 to rotate. The first motor 810 and the second motor 820 are connected to the pressure sensor 610 for signal connection.

[0058] When a pressure sensor 610 detects that the pressure value of the pressure sensor 610 below it is zero, the pressure sensor 610 sends an electrical signal to the first motor 810 and the second motor 820, so the first motor 810 and the second motor 820 switch the working mode, and the first motor 810 and the second motor 820 switch from clockwise synchronous rotation to reciprocating between clockwise rotation of a preset angle and counterclockwise rotation of a preset angle. After the material screening is completed, the staff can remove the damaged conveyor mesh belt 230 and replace it with a new conveyor mesh belt 230. It should also be noted that in order to make the first motor 810 drive the first drive shaft 210 to rotate, specifically, a driving gear 830 is fixedly connected to the output shaft of the first motor 810, and a driven gear 840 is fixedly connected to the end of the first drive shaft 210 close to the first motor 810, so that the driving gear 830 is meshed with the driven gear 840, and the connection between the second motor 820 and the second drive shaft 220 is similar, which will not be repeated.

[0059] It should also be noted that in order to prevent the mesh from continuing to break, when the pressure sensor 610 detects that the mesh is broken, the tension on the upper part of the conveyor belt 230 can be appropriately reduced, and the tension on the lower part of the conveyor belt 230 can be increased to prevent the mesh at other positions from breaking.

[0060] In a further embodiment, Figure 2 As shown, a feed inlet 120 is opened on the top of the chassis 100 , and the feed inlet 120 is connected to the screening chamber 110 downwards.

[0061] A feed inlet 120 is provided for feeding the material to be screened into the screening chamber 110 through the feed inlet 120 , so that the material falls onto the conveyor mesh belt 230 under the action of its own gravity.

[0062] In a further embodiment, a small particle discharge port 130 is opened at the bottom of the chassis 100 , and the small particle discharge port 130 is connected to the screening chamber 110 upward.

[0063] The small particle discharge port 130 is provided to collect the small particle material that falls to the bottom of the screening chamber 110 after screening.

[0064] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
