Description

Technical Field

[0001] This invention relates to the field of food processing and conveying technology, and in particular to a conveying device for crushing and granulating sodium carboxymethyl cellulose. Background Technology

[0002] In the granulation production of food additives such as sodium carboxymethyl cellulose (CMC), the conveying and handling of post-granulation materials is a crucial step in ensuring the smooth operation of continuous food processing lines. Currently, screw conveyors are widely used in the industry to handle the transfer and return of post-granulation materials.

[0003] However, as a core conveying equipment in industrial food processing, screw conveyors have significant technical defects during operation. Relying on the forced rotation of the screw blades to push materials is not only not intelligent enough, but this mechanical force will continuously squeeze, shear, and rub the granulated CMC particles. Since CMC particles themselves are brittle, under the squeezing action of the screw blades and the friction of the inner wall of the shell, a large number of intact particles will break and form fine powder. These fine powders not only change the particle size distribution of the finished product, reducing the appearance and batch consistency of the product, but more seriously, the fine powdered CMC is very likely to form fish-eye-like clumps in the food processing dissolution process, resulting in slower dissolution and incomplete dissolution, directly affecting the uniformity and stability of the food ingredient system, and thus reducing the production efficiency of downstream food processing and the quality of the final product. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a conveying device for crushing and granulating sodium carboxymethyl cellulose.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A conveying device for crushing and granulating sodium carboxymethyl cellulose includes: a conveying pipe and a chain disposed within the conveying pipe; and a storage component disposed on the chain for conveying granules. The storage component includes a box disposed on the chain, a filter plate rotatably disposed at the bottom of the box, and when the box moves, the powder inside the box is discharged through the filter plate, forming a separation of granules and powder. When the box moves to the discharge port of the conveying pipe, the filter plate opens.

[0006] Preferably, a connecting rod is provided on one side of the box body, and the filter plate is fixedly mounted on the connecting rod. A gear is fixedly mounted on one end of the connecting rod, and a torsion spring is sleeved on the connecting rod. A rack is fixedly mounted inside the conveying pipe, and the rack is located at the outlet of the conveying pipe.

[0007] Preferably, the top of the box is symmetrically and obliquely provided with two receiving plates for receiving materials.

[0008] Preferably, a vibration component for vibrating the box is provided between the chain and the box body.

[0009] Preferably, the vibration assembly includes a sliding rod symmetrically slidably disposed on the housing, a roller is disposed at the bottom of the sliding rod, and a spring is sleeved on the sliding rod. A support frame is fixedly disposed at the other end of the sliding rod, one of the support frames is fixedly disposed on the chain, and the other support frame is slidably disposed in the conveying pipe, with a ball bearing disposed at the connection point. A pair of corrugated plates that are in movable contact with the roller are disposed in the conveying pipe.

[0010] Preferably, the filter plate is provided with a cleaning component for cleaning the filter plate.

[0011] Preferably, the cleaning assembly includes a brush plate slidably disposed on the surface of the filter plate, and a corrugated tube is provided on one side of the brush plate, and a pull rope is fixedly disposed between the brush plate and the box body.

[0012] Preferably, a metering component is provided at the inlet of the conveying pipe, and when the chain rotates, the metering component intermittently injects material into the box. The metering component includes a cylinder fixedly installed on the conveying pipe, a rotating shaft is rotatably installed inside the cylinder, and a metering shaft is fixedly installed on the rotating shaft, and a metering groove is opened on the metering shaft.

[0013] Preferably, an airflow assembly is provided on one side of the cylinder; the airflow assembly includes a fixed cylinder fixedly mounted on the cylinder, a piston plate slidably mounted inside the fixed cylinder, a piston rod fixedly mounted at the bottom of the piston plate, a cam disk fixedly mounted at one end of the metering shaft, and a pull rod hinged between the cam disk and the piston rod, a collection box is provided on the conveying pipe, and the collection box is located at the corrugated plate, and the fixed cylinder communicates with the collection box and the top of the cylinder respectively.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the continuous vibration of the box during the conveying process, the powdery material in the granular material is discharged through the filter plate mesh, realizing the online automatic separation of granules and powders during the conveying process. There is no need to configure additional independent screening equipment, which shortens the process flow of food additives, reduces the equipment footprint and investment costs, and improves the integration and continuity level of food industrial production lines.

[0015] 2. By adopting an independent material loading and closed track conveying method, the forced pushing structure of the traditional screw conveyor is abandoned, which avoids the particles being squeezed, sheared and rubbed during the conveying process. This effectively ensures the uniformity of the particle size distribution of CMC particles, reduces the generation of fine powder from the source, ensures its solubility and thickening stability in food processing, and directly improves the quality of the final food.

[0016] 3. The gear and rack meshing drive the filter plate to automatically open at the discharge port and the torsion spring drive to automatically close, realizing the full automation of the quantitative reception, vibration separation and automatic unloading of materials in the closed conveying pipe, reducing manual intervention and improving the intelligent and automated operation level of food ingredient processing equipment.

[0017] 4. The sealed conveying pipe structure isolates the material from the outside air throughout the conveying process, preventing the performance of CMC from deteriorating due to moisture absorption and ensuring the quality stability of food additives during processing, which meets the requirements of clean and controllable environment for raw materials in industrial food production.

[0018] 5. The rotating shaft synchronously drives the cam plate to move the pull rod and piston plate back and forth, so that the material is dispersed by blowing air at the feed port of the cylinder and the powder is collected by suction in the collection box. This realizes the synchronous linkage between material dispersion and dust collection, avoids the powder from flying and being wasted in the closed conveying pipe, improves the material utilization rate, and reduces the raw material loss in the food ingredient processing process.

[0019] 6. When the filter plate is opened and closed, the pull rope links the brush plate to move and clean the surface of the filter plate. This achieves automatic cleaning of the filter plate mesh after each unloading, avoids mesh clogging, ensures the continuous and stable powder separation efficiency during long-term operation, reduces the frequency of equipment downtime maintenance, and improves the continuous operation efficiency of the food additive production line.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] In the description of this specification, the references to terms such as "embodiment," "one embodiment," "some implementations," "exemplary," and "one implementation," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or implementation of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0027] The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0028] Combination Figures 1-9 This invention provides a conveying device for crushing and granulating sodium carboxymethyl cellulose, comprising: a conveying pipe 1, and a chain 2 disposed within the conveying pipe 1; and a storage component 3 disposed on the chain 2 for conveying particles. The storage component 3 includes a box 31 disposed on the chain 2, with a filter plate 32 rotatably disposed at the bottom of the box 31. When the box 31 moves, the powder inside the box 31 is discharged through the filter plate 32, resulting in separation of particles and powder. When the box 31 moves to the discharge port of the conveying pipe 1, the filter plate 32 opens, connecting the conveying pipe 1 with the discharge port of the granulator. After crushing and granulating by the granulator, the particles enter the inlet of the conveying pipe 1 through the discharge port, and simultaneously enter the box 31 through the inlet. At this time, the filter plate 32 and the box 31 form a single unit, suitable for handling granular materials. The system effectively stores and transports materials while preventing breakage due to compression during transport. When chain 2 moves, it drives box 31 to move, causing vibration that allows powdery material in the granular material to pass through filter plate 32, separating the granular material from the powder and preventing powdery material from mixing into the finished product and affecting its quality. When box 31 moves to the outlet of conveying pipe 1, filter plate 32 opens, and the material inside box 31 is discharged. The circular motion of chain 2 ensures continuous transport of the storage component 3, separating the material during transport. The entire system forms a closed space within conveying pipe 1, reducing contact between the material and air, preventing moisture absorption, and avoiding compression during transport, thus reducing the generation of powdery material and ensuring transport quality.

[0029] Preferred, Reference Figure 4 and Figure 5A connecting rod is provided on one side of the box body 31, and the filter plate 32 is fixedly mounted on the connecting rod. A gear 34 is fixedly mounted on one end of the connecting rod, and a torsion spring 35 is sleeved on the connecting rod. A rack 36 is fixedly mounted inside the conveying pipe 1, and the rack 36 is located at the discharge port of the conveying pipe 1. The connecting rod is rotatably mounted on the box body 31, and one end of the torsion spring 35 is fixed to the connecting rod, and the other end is fixed to the connection between the connecting rod and the box body 31. When the box body 31 moves to the discharge port, the gear 34 contacts the rack 36. As the box body 31 moves, the gear 34 rotates, causing the filter plate 32 to gradually open. When the filter plate 32 opens, the material in the box body 31 is discharged. When the gear 34 and the rack 36 disengage, the torque of the torsion spring 35 drives the filter plate 32 to close again, so as to facilitate the next material storage and transportation. No additional power source is required. The automatic opening and closing of the filter plate 32 can be completed by the movement of the box body 31 itself. The structure is compact and the response is reliable.

[0030] Preferred, Reference Figure 4 The top of the box 31 is symmetrically and inclined with two receiving plates 33 for receiving materials. When the box 31 moves to the inlet of the conveying pipe 1, in order to ensure that all the materials enter the box 31, the receiving plates 33 effectively extend the receiving area on both sides of the box 31, ensuring that all the materials can enter the box 31 when falling, and avoiding the waste caused by the materials scattering outside the box 31. The inclined guiding design of the receiving plates 33 can also effectively reduce the splashing and rebound of materials when falling, further improving the falling accuracy and collection efficiency.

[0031] Preferred, Reference Figure 6 A vibration component 4 is provided between the chain 2 and the box 31 for the vibration of the box 31. It is used to connect the chain 2 and the box 31, and at the same time facilitates the separation of materials in the box 31, reducing the amount of powder in the granular material. The vibration component 4 converts the linear motion of the chain 2 into the high-frequency micro-amplitude vibration of the box 31, providing continuous power for the online screening of materials.

[0032] Preferred, Reference Figure 4 , Figure 5 and Figure 6The vibration assembly 4 includes sliding rods 41 symmetrically slidably mounted on the housing 31. A roller 42 is mounted at the bottom of the sliding rod 41, and a spring 43 is sleeved on the sliding rod 41. A support frame 44 is fixedly mounted at the other end of the sliding rod 41. One support frame 44 is fixedly mounted on the chain 2, and the other support frame 44 is slidably mounted inside the conveying pipe 1, with a ball bearing at the connection point. A pair of corrugated plates 45 are mounted inside the conveying pipe 1, which are in movable contact with the rollers 42. When the housing 31 moves to the corrugated plates 45, the rollers 42 and corrugated plates 45 come into contact, and... As the chain 2 continues to move, driving the box 31 to move, the roller 42 travels on the corrugated plate 45. Due to the unevenness of the corrugated plate 45, when the roller 42 moves, the sliding rod 41 will drive the box 31 to move up and down, and at the same time, the elasticity of the spring 43 will cause the box 31 to vibrate. When the box 31 vibrates, the powdery material inside the box 31 is discharged through the filter plate 32 to ensure that the material during conveying is all large particles, thereby improving the quality of the product. This vibration structure does not require external energy input and relies entirely on the mechanical movement during the conveying process, making it energy-efficient, highly efficient, and easy to maintain.

[0033] Preferred, Reference Figure 4 and Figure 5 The filter plate 32 is equipped with a cleaning assembly 5 for cleaning the filter plate 32. The cleaning assembly 5 includes a brush plate 51 slidably disposed on the surface of the filter plate 32, and a corrugated tube is provided on one side of the brush plate 51. A pull rope 52 is fixedly disposed between the brush plate 51 and the housing 31. Each time the filter plate 32 is closed, the pull rope 52 pulls the brush plate 51 to move, and at the same time, the corrugated tube on one side of the brush plate 51 is compressed. When the filter plate 32 is opened, the pull rope 52 gradually relaxes, and the corrugated tube pushes the brush plate 51 to move at the same time, so that the brush plate 51 reciprocates to clean the surface of the filter plate 32 each time the filter plate 32 is opened and closed, so as to avoid the mesh of the filter plate 32 being blocked by powdery materials and ensure the permeability of the filter plate 32 during long-term use. The cleaning assembly 5 is linked with the opening and closing action of the filter plate 32, without the need for additional control programs, ensuring that each conveying cycle is accompanied by an effective cleaning, and greatly extending the maintenance cycle of the filter plate 32.

[0034] Preferred, Reference Figure 8A metering component 6 is provided at the inlet of the conveying pipe 1, and when the chain 2 rotates, the metering component 6 intermittently injects material into the box 31. The metering component 6 includes a cylinder 61 fixedly mounted on the conveying pipe 1, a rotating shaft 62 rotatably mounted inside the cylinder 61, and a metering shaft 63 fixedly mounted on the rotating shaft 62, with a metering groove opened on the metering shaft 63. When the chain 2 moves, since the chain 2 is driven by a drive motor, and a gearbox 34 is also provided on the drive shaft of the drive motor, the drive motor drives the chain 2 to rotate while simultaneously driving the gearbox 34. The rotating shaft 62 rotates; when the rotating shaft 62 rotates, the metering shaft 63 rotates, and the material entering the metering trough is gradually conveyed to the lower side of the cylinder 61. When the metering trough is completely located under the cylinder 61, the box 31 is just located under the cylinder 61. Therefore, the box 31 will catch the material and then convey it. During the conveying, the material is shaken and finally discharged. Each conveying can be metered to facilitate the processing of subsequent materials. By setting the volume of the metering trough, the amount of material conveyed at one time can be precisely controlled, effectively avoiding fluctuations in subsequent processes caused by uneven feeding.

[0035] Preferred, Reference Figure 9 An airflow assembly 7 is provided on one side of the cylinder 61. The airflow assembly 7 includes a fixed cylinder 71 fixedly mounted on the cylinder 61, a piston plate 74 slidably mounted inside the fixed cylinder 71, a piston rod fixedly mounted at the bottom of the piston plate 74, a cam disk 72 fixedly mounted at one end of the metering shaft 63, and a pull rod 73 hinged between the cam disk 72 and the piston rod. A collection box 75 is provided on the conveying pipe 1, and the fixed cylinder 71 communicates with both the collection box 75 and the top of the cylinder 61. When the rotating shaft 62 rotates, it simultaneously drives the cam disk 72 to rotate. When the cam disk 72 rotates, it drives the pull rod 73 to move, and when the pull rod 73 moves, it pulls the piston plate 74 to move. Since two sets of air pipes are provided on the fixed cylinder 71, and the two sets of air pipes are located on the upper and lower sides of the piston plate 74 respectively, and each set of air pipes is equipped with a solenoid valve, the following occurs: when the piston plate 74 rises, the air pipe connected to the collection box 75 is in a suction state, and the air pipe connected to the cylinder 61 is in a suction state. The air pipe connected to 61 is opened; that is, when the piston plate 74 moves upward, the gas on the upper side of the piston plate 74 enters the upper side of the cylinder 61, forming an airflow with the falling material, which disperses the falling material and prevents the material from accumulating and clumping at the outlet of the cylinder 61; the suction effect formed at the bottom of the piston plate 74 collects the powdery material generated by the shaking of the box 31 through the collection box 75, avoiding the formation of dust in the conveying pipe 1 during the shaking of the material and causing material waste; the connection between the collection box 75 and the air pipe is equipped with filter cotton to prevent powdery material from entering the fixed cylinder 71, thus not only effectively collecting powdery material, but also ensuring that the material is in a dispersed state during conveying, improving the separation effect of the material; the airflow component 7 works in conjunction with the quantitative shaft 63, realizing quantitative feeding while simultaneously completing the anti-clogging and dust removal functions, forming an integrated collaborative operation, effectively improving the system's operational stability and material processing quality.

[0036] Working principle After being crushed and granulated by the granulator, the granulated material enters the feed inlet of the conveying pipe 1 through the discharge port and falls into the box 31. The receiving plate 33 extends the receiving area on both sides of the box 31 to ensure that all the material enters. The drive motor drives the chain 2 to move, and at the same time drives the rotating shaft 62 of the metering component 6 to rotate through the gear box 34. The rotation of the metering shaft 63 causes the material to enter the lower side of the cylinder 61 through the metering groove and fall into the box 31 moving below. Chain 2 drives box 31 to move along conveying pipe 1. When box 31 passes through the corrugated plate 45 area, roller 42 at the bottom of sliding rod 41 moves along the uneven corrugated plate 45. The roller 42 moves up and down, causing box 31 to move up and down. Combined with the elasticity of spring 43, box 31 vibrates continuously. Vibration causes powdery material in granular material to be discharged through the mesh of filter plate 32, realizing the separation of granules and powder. When rotating shaft 62, it drives cam disk 72 to rotate. Cam disk 72 drives piston plate 74 to reciprocate in fixed cylinder 71 through pull rod 73. When piston plate 74 rises, gas on the upper side of piston plate 74 enters the upper side of cylinder 61 and blows down the falling material to disperse it. On the lower side of piston plate 74, the air pipe connected to collection box 75 produces suction, sucking the powdery material generated by the shaking of box 31 into collection box 75. Filter cotton prevents powder from entering fixed cylinder 71. When the box 31 moves to the discharge port of the conveying pipe 1, the gear 34 on the connecting rod meshes with the rack 36 inside the conveying pipe 1. As the box 31 continues to move, the gear 34 rotates, driving the connecting rod and the filter plate 32 to gradually open, and the granular material inside the box 31 is discharged. After the gear 34 disengages from the rack 36, the torque of the torsion spring 35 drives the connecting rod and the filter plate 32 to rotate in the opposite direction to reset and close. Each time the filter plate 32 opens and closes, the pull rope 52 pulls the brush plate 51 to move along the surface of the filter plate 32, the bellows is compressed and released, and the brush plate 51 moves back and forth on the surface of the filter plate 32 to clean.

[0037] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
