Description

Technical Field

[0001] This utility model relates to a vacuum feeding machine for lactose powder, belonging to the field of lactose processing technology. Background Technology

[0002] Currently, lactose powder is a commonly used raw material in the food and pharmaceutical industries, and its conveying process must meet the core requirements of being dust-free and clean, having uniform composition, and low loss. Existing technologies mostly employ manual feeding or mechanical conveying equipment for feeding lactose powder. Manual feeding is not only inefficient but also prone to causing lactose dust to spill out, polluting the production environment, increasing raw material loss, and posing a health risk to operators from inhaling dust. Mechanical conveying equipment, on the other hand, is prone to generating heat due to mechanical friction, which can damage the physicochemical properties of lactose. Furthermore, material residue can easily remain in the gaps between equipment, causing cross-contamination, and lactose stratification can easily occur during conveying, affecting the compositional uniformity of subsequent products.

[0003] Meanwhile, most existing vacuum feeding equipment has a general-purpose structure. On the one hand, the negative pressure stability of general-purpose vacuum generators is insufficient, and the vacuum level is prone to drop sharply due to lactose adhering to the filter element, which affects the conveying efficiency. On the other hand, lactose is prone to accumulate and clump on the inner wall of the hopper, which not only wastes raw materials but also increases the difficulty of cleaning and maintaining the equipment.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a lactose powder vacuum feeding machine, which would have greater industrial application value. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a vacuum feeding machine for lactose powder.

[0006] This utility model discloses a vacuum feeding machine for lactose powder, comprising a frame structure mounting bracket. A horizontal feeding worktable is provided on the top surface of the mounting bracket. A feeding body is quickly and detachably mounted on the feeding worktable. A feeding railing is installed around the surface of the feeding worktable to ensure worker safety during high-altitude operations. A circular through-hole is provided on the surface of the feeding worktable for mounting the feeding body. Multiple vibration supports are evenly distributed on the outer wall of the feeding body. Multiple vibration mechanisms are provided around the edge of the circular through-hole on the surface of the feeding worktable. The vibration supports are quickly and detachably mounted on the top surface of the vibration mechanisms. The vibration mechanism is a vibration motor with a set of adjustable eccentric blocks mounted at each end of the rotor shaft. The centrifugal force generated by the high-speed rotation of the shaft and eccentric blocks generates excitation force, thereby driving the entire feeding body to vibrate rhythmically after the vacuum feeding machine finishes feeding, thus vibrating and removing the lactose clumps accumulated on the inner wall of the feeding body. Furthermore, the feeding body includes a cylindrical sealed silo, which is completely sealed to prevent dust leakage. Multiple feeding pipes are evenly arranged on the side wall of the sealed silo, connecting the lactose raw material silo to the feeding machine to achieve negative pressure suction and conveying. A filter chamber is connected through the top of the sealed silo, and a vacuum generator and a pulse backflushing device are respectively connected to the top side wall of the filter chamber. The filter chamber is used to separate the air-material mixture, and the pulse backflushing device cleans the filter element with compressed air to prevent lactose adhesion and clogging. The vacuum generator generates negative pressure to draw lactose from the raw material container into the sealed silo through the pipes, ensuring no dust spillage throughout the process, meeting the cleanliness requirements of lactose. A conical discharge hopper is connected through the bottom of the sealed silo. After the negative pressure disappears, the lactose falls into the discharge hopper by gravity for centralized unloading to downstream equipment. Combined with the pulse backflushing device, powdery lactose can be recovered for reuse. Furthermore, a filter element mounting top plate is fixedly installed inside the filter chamber, and multiple filter element cylinders are suspended on the bottom surface of the filter element mounting top plate. The top surface of each filter element cylinder is penetrated through the filter element mounting top plate to form a filter element top opening.

[0007] Furthermore, the top of the pulse backflushing device is connected to the pulse top pipes arranged on the top of the filter chamber via a pulse connecting pipe. Multiple pulse branch pipes are provided on the bottom surface of the pulse top pipes, each corresponding to an opening on the top of a filter element. This is used to generate air pressure exchange between the vacuum generator and the pulse backflushing device and the sealed hopper, completing the filtration and backflushing cleaning. Furthermore, the mounting frame has a height of 2-2.5m and an opening on one side for inserting and docking the lactose collection tank. Furthermore, the number of vibration mechanisms and the number of vibration supports are equal and are matched with each other.

[0008] By means of the above-described solution, the present invention has at least the following advantages: (1) The pulse oscillation unit of this utility model can precisely control the oscillation intensity and frequency according to the lactose adhesion characteristics, efficiently peel off the dense lactose dust layer on the surface of the filter element, avoid the problem of sudden drop in vacuum caused by filter element blockage, keep the vacuum system in a stable negative pressure, improve the conveying efficiency by more than 30%, and reduce the frequency of shutdown cleaning, significantly enhancing the continuity of production.

[0009] (2) Pulse oscillation can act synchronously on the inner wall of the silo, effectively preventing lactose powder from accumulating and clumping. The residual rate of raw materials is reduced from 5%~8% in the existing technology to less than 1%, greatly reducing the waste of high-value lactose. At the same time, the filter element has a service life that is extended by more than 2 times due to the rapid removal of adhering substances, and the equipment cleaning and maintenance time is reduced by 60%, which reduces the production and operation costs.

[0010] (3) The fully enclosed conveying and pulse oscillation design without mechanical friction not only avoids the mechanical and thermal damage to the physical and chemical properties of lactose, but also prevents dust from spilling out and polluting the environment, which meets the food / GMP clean production standards; and the negative pressure conveying combined with the pulse anti-separation effect makes the uniformity of lactose components maintain a rate of over 99%, ensuring the quality stability of downstream products.

[0011] (4) The pulse oscillation function can be flexibly adjusted according to the humidity, flowability and other parameters of lactose to meet the conveying needs of different batches and specifications of lactose powder; at the same time, the dust collection and recycling unit and the pulse system are integrated into the design, which reduces the space occupied by the equipment and increases the dust recycling rate to more than 98%, further reducing the cost of raw materials.

[0016] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0017] See Figure 1 A preferred embodiment of the present invention provides a lactose powder vacuum feeding machine, comprising a frame structure mounting frame 1 with a height of 2-2.5m, an opening on one side of the mounting frame 1 for inserting and connecting a lactose collection tank; a horizontal feeding worktable 2 is provided on the top surface of the mounting frame 1, on which a feeding body 3 is quickly and detachably mounted; and feeding railings 4 are installed around the surface of the feeding worktable 2 to ensure the safety of workers operating at height. See Figures 2-4 The surface of the feeding workbench 2 is provided with a circular through hole for installing the feeding body 3. Multiple vibration brackets 312 are evenly provided on the outer wall of the feeding body 3. Multiple vibration mechanisms 21 are provided at the edge of the circular through hole on the surface of the feeding workbench 2. The number of vibration mechanisms 21 is equal to the number of vibration brackets 312 and they are matched with each other. The vibration brackets 312 can be quickly installed and disassembled on the top surface of the vibration mechanism 21. The vibration mechanism 21 is a vibration motor with a set of adjustable eccentric blocks installed at both ends of the rotor shaft. The centrifugal force generated by the high-speed rotation of the shaft and the eccentric blocks is used to obtain the excitation force, thereby driving the entire feeding body 3 to vibrate rhythmically after the vacuum feeder finishes feeding, thereby vibrating and removing the lactose clumps accumulated on the inner wall of the feeding body 3. The feeding body 3 includes a cylindrical sealed hopper 31, which is completely sealed to prevent dust leakage. Multiple feeding pipes 311 are evenly arranged on the side wall of the sealed hopper 31. These feeding pipes 311 connect the lactose raw material hopper to the feeding machine, enabling negative pressure suction and conveying. A filter chamber 32 is connected through the top of the sealed hopper 31. A vacuum generator 34 and a pulse backflushing device 35 are respectively connected to the top side wall of the filter chamber 32. The filter chamber 32 is used to separate the gas-material mixture. The pulse backflushing device 35 cleans the filter element by backflushing with compressed air to prevent lactose from adhering and clogging. The vacuum generator 34 is used to generate negative pressure, which draws lactose from the raw material container into the sealed silo through the pipeline. There is no dust spillage throughout the process, which meets the cleanliness requirements of lactose. The bottom of the sealed silo 31 is connected to a conical discharge hopper 33. After the negative pressure disappears, the lactose falls into the discharge hopper by gravity for centralized unloading to downstream equipment. The pulse backflushing device 35 can be used to recover powdery lactose for reuse. The filter chamber 32 is fixedly provided with a filter element mounting top plate 361. Multiple filter element cylinders 36 are suspended on the bottom surface of the filter element mounting top plate 361. The top surface of each filter element cylinder 36 is connected through the filter element mounting top plate 361 to form a filter element top opening 362, which is used to generate air pressure exchange between the vacuum generator 34 and the pulse backflushing device 35 and the sealed silo 31 to complete filtration and backflushing cleaning. The pulse backflushing device 35 is connected to the pulse top pipe 352 arranged on the top of the filter chamber 32 via a pulse connecting pipe 351. Multiple pulse branch pipes 353 are provided on the bottom surface of the pulse top pipe 352, and each pulse branch pipe 353 corresponds to a filter element top opening 362.

[0018] The working principle of this utility model is as follows: In actual use, after the vacuum generator 34 is started, a stable negative pressure is formed through the top opening of the filter element in the filter chamber 32. This negative pressure is transmitted along the sealed hopper 31 to the feeding pipe 311, which draws the lactose powder in the lactose raw material hopper into the sealed hopper 31 through the feeding pipe 311. The entire process is driven by negative pressure, with no dust spillage, which meets the clean conveying requirements of lactose.

[0019] After the airflow containing lactose powder enters the sealed silo 31, the airflow carries the lactose powder upward to the filter chamber 32. The filter cartridge 36 in the filter chamber 32 filters the airflow, and the lactose powder is trapped on the outer wall of the filter cartridge 36 and in the sealed silo 31. The filtered clean airflow passes through the filter cartridge 36, and is discharged through the top opening of the filter cartridge and the vacuum generator 34, thus completing the gas-material separation.

[0020] As the conveying process progresses, lactose powder easily adheres to the outer wall of the filter cartridge 36. At this time, the pulse backflushing device 35 is activated. Compressed air enters the pulse top pipe 352 through the pulse connecting pipe 351, and then through the pulse branch pipe 353 corresponding to the top opening of the filter cartridge, a high-pressure pulse airflow is injected into the filter cartridge 36. The airflow impacts the outer wall of the filter cartridge 36 in the opposite direction, blowing the adhered lactose powder off into the sealed hopper 31, avoiding filter cartridge blockage and vacuum reduction, and ensuring conveying efficiency.

[0021] After the vibration mechanism 21 on the surface of the feeding workbench 2 is started, it drives the entire feeding body 3 to generate rhythmic vibration through the matching vibration bracket 312, which shakes off the lactose powder accumulated in the inner wall of the sealed hopper 31 and the conical discharge hopper 33, preventing lactose from clumping and leaving residue, and reducing raw material waste.

[0022] When the lactose powder in the sealed silo 31 reaches the preset amount, the vacuum generator 34 stops working, the negative pressure disappears, and the lactose powder in the sealed silo 31 falls along the conical discharge hopper 33 under its own gravity, and is connected to the downstream equipment to complete the unloading. During the unloading process, a small amount of dust that has not completely fallen can be further removed by pulse backflushing and vibration, and at the same time, dust recycling and reuse can be achieved.
