Description

Technical Field

[0001] This utility model belongs to the field of extraction equipment technology, and specifically relates to a triple-filtration dry material extraction device, which is used to improve extraction efficiency and purity, and is suitable for the extraction and processing of dry materials in the food and other industries. Background Technology

[0002] In industries such as food, the extraction of dry materials typically involves using an extraction tank. The dry materials are placed in the tank, water is added, and the mixture is cooked at a controlled temperature to extract the essence from the dry materials into a liquid. During the extraction process, the smaller the particle size of the dry materials, the better the extraction process. However, if the particles are too small, they can easily enter the liquid material pipeline, causing blockages and affecting extraction efficiency and purity. Utility Model Content

[0003] This invention addresses the problem that while smaller particles are more conducive to extraction in existing dry material extraction equipment, excessively small particles can easily enter the liquid material pipeline, causing blockages and affecting extraction efficiency and purity. It provides a triple-filtration dry material extraction device that filters dry material particles from large to small through three stages of filtration, thereby improving extraction efficiency and purity.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a dry material extraction device with triple filtration, including a tank body, a hollow support seat in the middle of the tank body, a first-stage basket filter screen placed above the hollow support seat, a second-stage filter screen placed below the hollow support seat, a liquid outlet at the bottom of the tank body, and a third-stage filter screen placed above the liquid outlet.

[0005] This device employs a three-stage filtration system to progressively filter the dry material within the tank. Particles are filtered according to size, preventing clogging of any single filter layer and thus reducing liquid throughput. It also prevents excessively large particles from entering and clogging the liquid pipelines. Furthermore, the circulating liquid continuously flushes away dry particles from the filter screens, improving extraction efficiency.

[0006] Preferably, the mesh size of the primary basket filter, secondary filter, and tertiary filter gradually increases.

[0007] Preferably, the bottom of the primary basket filter is provided with a 30-50 mesh filter, the secondary filter is a 50-80 mesh filter, and the tertiary filter is an 80-120 mesh filter.

[0008] Preferably, the top of the primary basket filter screen is equipped with a handle that connects to an external hook for lifting and lowering. The primary basket filter screen is placed on the hollow support base by lifting and lowering using the external hook.

[0009] Preferably, the secondary filter is a cone-shaped filter with a higher center and a lower circumference.

[0010] Preferably, the tertiary filter is a funnel-shaped filter with a lower center and a higher circumference. The secondary and tertiary filters are oriented in opposite directions and spatially offset to fully utilize their filtration capacity.

[0011] Preferably, a reflux pipe is provided on one side of the tank, with the inlet of the reflux pipe connected to the lower part of the tank and the outlet of the reflux pipe connected to the upper part of the tank. The reflux pipe allows the liquid to circulate inside the tank, improving extraction efficiency and enhancing the extraction effect.

[0012] Preferably, the sidewall of the tank is provided with a sandwich structure for temperature control.

[0013] Preferably, the top of the tank is provided with a top cover that is opened and closed by a hydraulic rod.

[0014] Preferably, the top cover is provided with a top observation port.

[0015] This invention employs a three-stage filter system to perform triple-stage filtration of the dry material inside the tank. The dry material particles are filtered step by step according to their size, preventing dry material particles from clogging a certain layer of the filter screen and reducing the liquid flow capacity. It also prevents excessively large dry material particles from entering the liquid pipe and clogging it. Furthermore, the liquid continuously washes the dry material particles on the filter screen during the circulation process, improving the extraction efficiency. Attached Figure Description

[0019] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0020] Example: A triple-filtration dry material extraction device, such as... Figure 1 As shown. This equipment includes a tank 3, with a support 8 at the bottom of the tank 3. In this example, the support 8 consists of three circumferentially evenly distributed feet. A top cover 10 is provided on the top of the tank, which is opened and closed by a hydraulic rod 2. A top observation port 1 is provided on the top cover 10. The side wall of the tank 3 is provided with a sandwich structure for temperature control. A return pipe 9 is provided on one side of the tank 3, with the inlet of the return pipe connected to the lower part of the tank and the outlet of the return pipe connected to the upper part of the tank.

[0021] A perforated support base 5 is provided in the middle of the tank body 3. A primary basket filter 4 is placed above the perforated support base, and a secondary filter 6 is placed below the perforated support base. A liquid outlet is provided at the bottom of the tank body, and a tertiary filter 7 is placed above the liquid outlet. The primary basket filter 4 has a 40-mesh filter at its bottom, the secondary filter 6 has a 60-mesh filter, and the tertiary filter 7 has a 100-mesh filter. The secondary filter 6 is a conical filter with a higher center and a lower circumference. The tertiary filter 7 is a funnel-shaped filter with a lower center and a higher circumference.

[0022] The top of the primary basket filter 4 is equipped with a handle that connects to an external hook for lifting and lowering. The primary basket filter 4 is pulled into and out of the tank 3 by the external hook.

[0023] In operation, the top cover 10 is opened using the hydraulic rod 2. Then, the primary basket filter 4, containing the dry material to be extracted, is placed onto the perforated support base 5 using the external hook, and liquid material is added. After closing the top cover 10, the temperature inside the tank is controlled by the temperature control jacket of the tank body 3. Simultaneously, the reflux pipeline is activated to circulate the liquid material within the tank. A circulation pump is installed on the reflux pipeline. During the extraction process, the dry material particles pass through the primary basket filter 4 and the secondary filter 6 for filtration and diversion, preventing clogging of the tertiary filter 7. This ensures smooth material filtration without clogging. The top cover may or may not have a liquid replenishment port, depending on requirements.
