Description

Technical Field

[0001] This utility model belongs to the field of lime milk preparation technology, and particularly relates to a lime milk preparation and screening device. Background Technology

[0002] The screening process in lime milk preparation aims to remove undigested particles and other mechanical impurities from the slurry after quicklime digestion, so as to ensure the fineness, uniformity and chemical activity of the final lime milk product.

[0003] High-frequency vibrating screens or rotary vibrating screens are typically used. The micro-amplitude high-frequency vibrations generated by these screens force the slurry through a screen with a specific aperture, effectively separating qualified slurry from coarse particles. The latter are discharged as waste residue. This process directly affects the operating efficiency, product quality, and equipment safety of subsequent chemical processes.

[0004] However, the core problem with traditional steel helical springs is that their near-ideal linear elasticity results in extremely poor damping effect, and vibration energy cannot be effectively dissipated. This causes dangerous amplitude amplification when the equipment crosses the resonance zone during start-up and shutdown, seriously threatening structural safety. Furthermore, the screen body will still have residual shaking for a long time after shutdown, requiring the addition of a damper for use, which increases system complexity and space occupation. Therefore, we propose a lime slurry preparation screening device. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides a lime milk preparation and screening device.

[0006] This invention is implemented as follows: a lime slurry preparation and screening device includes a support plate and an elastic support assembly, the elastic support assembly being fixed to the upper part of the support plate; a vibrating screen assembly, the vibrating screen assembly being fixed to the upper part of the elastic support assembly, the elastic support assembly providing space for movement and elastic support for the vibration of the vibrating screen assembly; wherein, the elastic support assembly includes a connecting seat, a support seat, and a connecting plate, several rubber blocks are inserted and installed inside the square grooves of the connecting seat and the support seat, two square tubes are fixedly connected to one side of the connecting plate, the square tubes on the side of the connecting plate closer to the connecting seat are inserted into the square grooves formed by the rubber blocks in the connecting seat; the square tubes on the side of the two connecting plates away from the connecting seat are respectively inserted and fixed into the square grooves formed by the rubber blocks in the support seats on the support plate and the vibrating screen assembly; the square tubes are rotatably arranged in the square grooves, and when the vibrating screen assembly is working, the square tubes rotate and compress the rubber blocks, and when the vibrating screen assembly stops working, the rubber blocks achieve rapid vibration reduction.

[0007] As a preferred embodiment of this utility model, the lower part of the support plate is provided with a support frame, the support frame is used to place in the work area, and the support plate is fixed to the upper part of the support frame.

[0008] As a preferred embodiment of this utility model, a grooved plate is slidably installed on the upper part of the support frame. The grooved plate is located below the support plate. In use, one output end of the vibrating screen assembly discharges the screened waste material, and the other output end of the vibrating screen assembly guides and transmits the screened material to the grooved plate for collection.

[0009] As a preferred embodiment of the present invention, the vibrating screen assembly includes a vibrating screen plate, and each of the elastic support components is provided with two support seats, which are respectively fixed to the upper part of the support plate and the lower part of the vibrating screen plate.

[0010] As a preferred embodiment of this utility model, baffles are fixedly installed on the upper three sides of the vibrating screen plate, and a waste output end is formed on one side of the vibrating screen plate. A vibration motor is fixedly installed outside the limiting plate at the lower part of the vibrating screen plate.

[0011] As a preferred embodiment of this utility model, two inclined plates are fixedly connected to the lower part of the vibrating screen plate, and a transmission plate is fixedly connected to the lower part of the inclined surface of the two inclined plates. A discharge gap is formed between the transmission plate and the limiting plate. The discharge gap communicates with a plurality of screen holes opened in the middle of the vibrating screen plate for guiding and transmitting the screened raw materials for lime milk preparation.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] When the vibrating motor in the vibrating screen assembly is started, the generated excitation force drives the screen box to vibrate and screen the lime slurry. This vibration is transmitted to the support seat at the top of the elastic support assembly below. The vulcanized rubber block in the support seat tightly wraps the square tube connected to it. The vibration energy forces the square tube to produce a small rotational movement in the square groove formed by the rubber block, rather than the traditional up and down extension. The vertical linear vibration is efficiently converted into a composite stress on the rubber material. The rotation of the square tube strongly squeezes and twists the rubber block, causing the internal molecular chains to generate severe friction. This friction irreversibly converts the harmful kinetic energy generated in the screening operation into heat energy, which is continuously dissipated into the external environment, thus providing a huge damping force.

[0014] This process solves the inherent defects of traditional steel springs: in the resonant speed range that the equipment inevitably passes through during startup and shutdown, this huge damping can instantly suppress the abnormal amplification of amplitude, absolutely ensuring structural safety. When stopping, the energy is quickly consumed, and the screen body has no residual kinetic energy to maintain shaking, achieving a stable state that stops immediately, completely eliminating the long-term residual shaking after traditional equipment stops;

[0015] The entire system provides flexible support through the elastic deformation of rubber and consumes energy through its viscous properties, integrating elasticity and damping functions. It requires no external additional devices, has a compact structure, and is extremely reliable, significantly improving the efficiency and safety of lime slurry screening.

[0023] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0024] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 4As shown, the lime slurry preparation and screening device provided in this embodiment of the present invention includes a support plate 1 and an elastic support component 2, which is fixed to the upper part of the support plate 1; a vibrating screen component 3, which is fixed to the upper part of the elastic support component 2, and the elastic support component 2 provides movement space and elastic support for the vibration of the vibrating screen component 3; wherein, the elastic support component 2 includes a connecting seat 205, a support seat 201 and a connecting plate 204, and a plurality of rubber blocks 202 are inserted and installed in the square grooves of the connecting seat 205 and the support seat 201, and one side of the connecting plate 204 is fixed. The fixed connection has two square tubes 203. The square tube 203 on the side of the connecting plate 204 near the connecting seat 205 is inserted into the rubber block 202 in the connecting seat 205, which has a square groove. The square tubes 203 on the side of the two connecting plates 204 away from the connecting seat 205 are respectively inserted into the square grooves formed by the rubber block 202 in the support seat 201 on the support plate 1 and the vibrating screen assembly 3. The square tubes 203 are rotatably set in the square grooves. When the vibrating screen assembly 3 is working, the square tubes 203 rotate and compress the rubber block 202. When the vibrating screen assembly 3 stops working, the rubber block 202 achieves rapid vibration reduction.

[0026] In the above-mentioned lime slurry preparation and screening device, when the vibrating motor 307 in the vibrating screen assembly 3 is started, the generated excitation force drives the screen box to vibrate and screen the lime slurry. The vibration is transmitted to the support seat 201 at the top of the elastic support assembly 2 below. The rubber block 202 fixed by vulcanization in the support seat 201 tightly wraps the square tube 203 connected to it. The vibration energy forces the square tube 203 to produce a small rotational movement in the square groove formed by the rubber block 202, rather than the traditional up and down extension.

[0027] The vertical linear vibration is efficiently converted into composite stress on the rubber material. The rotation of the square tube 203 forcefully squeezes and twists the rubber block 202, causing the internal molecular chains to generate intense friction. This friction irreversibly converts the harmful kinetic energy generated during the screening operation into heat energy, which is continuously dissipated into the external environment, thus providing a huge damping force and achieving the shock absorption effect.

[0028] In this embodiment, a support frame 4 is provided at the lower part of the support plate 1. The support frame 4 is used to place the support plate 1 on the work site. The support plate 1 is fixed on the upper part of the support frame 4. A groove plate 5 is also slidably installed on the upper part of the support frame 4. The groove plate 5 is located at the lower part of the support plate 1. When in use, one output end of the vibrating screen assembly 3 discharges the screened waste material, and the other output end of the vibrating screen assembly 3 guides the screened material to the groove plate 5 for collection.

[0029] After the vibrating screen assembly 3 completes the screening, its two output ends perform the sorting action:

[0030] Coarse waste particles that cannot pass through the screen will be discharged from the system at one end;

[0031] The other end will discharge and guide the qualified fine lime slurry to the top of the trough plate 5;

[0032] Since the trough plate 5 is installed on the support frame 4 through a slide rail or guide rail mechanism and is located below the support plate 1, it can slide in a certain direction to adjust its position, thereby accurately receiving the falling slurry and collecting and guiding it to the designated collection container or subsequent process pipeline, realizing the automated separation and collection of waste residue on the screen and finished material under the screen, which greatly improves the continuity and efficiency of operation.

[0033] In this embodiment, the vibrating screen assembly 3 includes a vibrating screen plate 301. Each elastic support assembly 2 is provided with two support seats 201. The two support seats 201 are fixed to the upper part of the support plate 1 and the lower part of the vibrating screen plate 301, respectively. Baffles 303 are fixedly installed on three sides of the upper part of the vibrating screen plate 301, and a waste output end is formed on one side of the vibrating screen plate 301. A vibration motor 307 is fixedly installed on the outside of the limiting plate 306 fixed to the lower part of the vibrating screen plate 301. Two inclined plates 304 are also fixedly connected to the lower part of the vibrating screen plate 301. A transmission plate 305 is fixedly connected to the lower part of the inclined surface of the two inclined plates 304. A discharge gap 308 is formed between the transmission plate 305 and the limiting plate 306. The discharge gap 308 communicates with several screen holes 302 opened in the middle of the vibrating screen plate 301 for guiding and transmitting the screened lime milk preparation raw materials.

[0034] The vibrating screen plate 301 is connected to the elastic support assembly 2 via the support base 201 installed on its upper and lower parts. It not only provides elastic support and room for movement, but also utilizes the shear deformation of the rubber block 202 to efficiently dissipate vibration energy and ensure smooth operation.

[0035] The lime slurry to be screened is put into the screening chamber consisting of a vibrating screen plate 301 and three side baffles 303. Under the action of vibration, the slurry is evenly distributed.

[0036] The fine slurry that meets the particle size requirements passes through the sieve hole 302 in the middle of the vibrating sieve plate 301 under the action of gravity and vibration, and falls into the space below it.

[0037] The bottom of the vibrating screen plate 301 is cleverly designed with two inclined plates 304 and a transmission plate 305, which together form a guide collection channel: qualified slurry passing through the screen hole 302 slides down the inclined plate 304 to the surface of the transmission plate 305 and flows along its inclined surface. Finally, it is discharged in a concentrated manner through the discharge gap 308 formed between the transmission plate 305 and the limiting plate 306, and becomes the finished product guide trough plate 5 for collection.

[0038] Large particles and waste residue that fail to pass through the sieve hole 302 are intercepted on the surface of the vibrating sieve plate 301 by the sieve mesh. Under the action of continuous vibration thrust and its own gravity, they move along the sieve surface and are eventually discharged from the specially formed waste output end on one side of the vibrating sieve plate 301, thereby realizing the continuous automated screening and separation of lime slurry and waste residue.

[0039] The working principle of this utility model:

[0040] When the vibrating motor 307 in the vibrating screen assembly 3 is started, the generated excitation force drives the screen box to vibrate and screen the lime slurry. This vibration is transmitted to the support seat 201 at the top of the elastic support assembly 2 below. The vulcanized rubber block 202 in the support seat 201 tightly wraps the square tube 203 connected to it. The vibration energy forces the square tube 203 to produce a small rotational movement in the square groove formed by the rubber block 202, rather than the traditional up and down extension. The vertical linear vibration is efficiently converted into a composite stress on the rubber material. The rotation of the square tube 203 strongly squeezes and twists the rubber block 202, causing the internal molecular chains to generate severe friction. This friction irreversibly converts the harmful kinetic energy generated in the screening operation into heat energy and continuously dissipates it to the external environment, thereby providing a huge damping force and achieving a shock absorption effect.
