Description

Technical Field

[0001] This utility model relates to the field of solid material processing technology, and in particular to a component for material screening and grinding. Background Technology

[0002] In the pharmaceutical industry, sieving and grinding are common material handling processes, typically accomplished using separate sieving and grinding machines. However, for reactive materials, due to their unique characteristics, sieving and grinding operations must be performed in a highly enclosed environment.

[0003] Currently, the commonly used process mainly involves placing the screening components (screening machine) and grinding components (grinding mill) in separate isolators. Operators use gloves in the isolators to screen and grind highly active materials in a closed environment. The main drawback of this process is its low production efficiency, making it unsuitable for mass production.

[0004] In addition, there is already a highly enclosed screening device in the existing technology, see details. Figure 1 The equipment includes a material hopper, a first high-tightness shut-off valve, a material storage section, a rotary valve, a screening component, a material discharge pipe, a second high-tightness shut-off valve, and a material collector. The material hopper and the material storage section are connected by high-tightness shut-off valves, as are the material discharge pipe and the material collector. The rotary valve regulates the material discharge speed and effectively prevents material blockage through the opening and closing of the valve plate. The entire material screening process is completed between the two high-tightness shut-off valves, ensuring good sealing and meeting the environmental requirements for screening highly reactive materials. It also offers high screening efficiency, making it suitable for mass production. However, this equipment is only suitable for screening highly reactive materials and cannot be used for grinding.

Detailed Implementation

[0031] The technical solutions of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] refer to Figure 2 This invention illustrates a material screening and grinding assembly, comprising:

[0033] Material bucket,

[0034] The material storage section is connected to the material barrel outlet via a first high-tightness valve.

[0035] A rotary valve is provided at the outlet of the material storage section to control the discharge speed;

[0036] A material conveying section is located at the outlet of the rotary valve;

[0037] The three-way valve includes a three-way valve inlet, a valve core, a three-way valve first outlet, and a three-way valve second outlet, wherein the three-way valve inlet is connected to the outlet of the material conveying section;

[0038] A screening component is disposed at the first discharge port of the three-way valve;

[0039] A grinding element is disposed at the second discharge port of the three-way valve;

[0040] The three-way pipe includes a first feed inlet, a second feed inlet, and a discharge outlet. The first feed inlet is connected to the discharge outlet of the screening component, and the second feed inlet is connected to the discharge outlet of the grinding component.

[0041] The material collector is connected to the outlet of the three-way pipe via a second high-tightness valve.

[0042] The material screening and grinding component provided in this embodiment of the utility model is an improvement on the existing high-enclosure screening device. By adding a material conveying section and a three-way valve, a grinding component (grind mill) is added. The improvement to the device is minimal and the improvement cost is low. It can both screen and grind materials (especially highly reactive materials) and meet the environmental requirements for processing highly reactive materials. Both screening and grinding are carried out in a closed environment.

[0043] The material screening and grinding assembly provided by this utility model includes a material hopper for feeding. After feeding is completed, the first high-tightness valve closes, and at the same time, the second high-tightness valve is also closed. The process section between the first and second high-tightness valves is in a closed state, providing a high-tightness screening or grinding environment for highly reactive materials. After feeding, the material is temporarily stored in a material storage section. According to the needs, the opening of the rotary valve is controlled to control the material feeding speed. Then, according to the screening or grinding requirements, the three-way valve is controlled to connect the screening component or the grinding component for corresponding processing operations. After processing, the discharge port of the screening component or the discharge port of the grinding component is opened, and the second high-tightness valve is opened. The material is collected into the material collector through the three-way pipe, thereby completing the screening or grinding of the material. The production efficiency is high and it is suitable for large-scale industrial production. In this invention, the screening and grinding components can be, for example, existing equipment, with matching three-way valves and three-way pipes. The screening component can be, for example, an S10 screening machine, and the grinding mill can be, for example, a U10X grinding mill. It should be noted that, unless otherwise specified, the feed inlet and discharge outlet are related to the upstream and downstream processes. The feed inlet refers to the interface connecting to the upstream process, and the discharge outlet refers to the interface connecting to the downstream process.

[0044] In one specific embodiment, the inlet of the screening component is connected to the first outlet of the three-way valve via a first conveying channel; the inlet of the grinding component is connected to the second outlet of the three-way valve via a second conveying channel. Preferably, a sealing ring is provided between the inlet of the screening component and the first conveying channel, and a sealing ring is provided between the inlet of the grinding component and the second conveying channel. Understandably, when screening is required, the three-way valve connects the material conveying section to the screening component, allowing the material to sequentially pass through the first outlet of the three-way valve and the first conveying channel to the screening component for screening. After screening, the outlet of the screening component and the second high-tightness valve are opened, and the screened material flows from the outlet of the screening component to the first inlet of the three-way pipe, and then from the outlet of the three-way pipe to the material collector. When grinding is required, the three-way valve connects the material conveying section to the grinding element, allowing the material to pass sequentially through the second outlet of the three-way valve and the second conveying channel to the grinding element for grinding. After grinding, the outlet of the grinding element and the second high-tightness shut-off valve are opened, and the ground material flows from the outlet of the grinding element to the second inlet of the three-way pipe, and then from the outlet of the three-way pipe to the material collector. Screening and grinding operations are preferably not performed simultaneously. Furthermore, sealing rings are installed between the inlet of the screening element and the first conveying channel, between the inlet of the grinding element and the second conveying channel, between the outlet of the screening element and the first inlet of the three-way pipe, and between the outlet of the grinding element and the second inlet of the three-way pipe to enhance sealing.

[0045] In one specific embodiment, the valve core has a material channel, the inlet of which is connected to the outlet of the material conveying section. Preferably, the valve core is rotated to connect the material conveying section to the screening component via the first outlet of the three-way valve; or to connect the material conveying section to the grinding component via the second outlet of the three-way valve. Understandably, the three-way valve connects the material conveying section to the first conveying channel or the material conveying section to the second conveying channel via the material channel of the valve core. The inlet of the material channel is always connected to the outlet of the material conveying section. By rotating the valve core, when the outlet of the material channel is rotated to the first outlet of the three-way valve, a screening operation can be performed on the material. Similarly, when rotated to the point where the outlet of the material channel connects to the second outlet of the three-way valve, a grinding operation can be performed on the material. It should be noted that the three-way valve can be a conventional three-way valve from the existing technology. The rotation of the valve core can be achieved by manual adjustment or by an automated program. Since this is the existing technology, it will not be described in detail here.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
