[0002] Diatomaceous earth is a biologically generated siliceous sedimentary rock. It is mainly composed of the remains of ancient diatoms. Its chemical composition is mainly SiO2. my country has huge reserves of diatomaceous earth, which is a valuable asset. Diatomaceous earth is usually light yellow or light gray, soft, porous and light, with strong hydrophilic water absorption. It is often used in industry as thermal insulation materials, filter materials, fillers, grinding materials, water glass raw materials, etc. Due to the strong water absorption of diatomaceous earth materials, its huge reserves and strong plasticity, it has been widely used in home decoration and daily necessities in recent years. Among them, diatomaceous earth absorbent pads are an emerging product. When making diatomaceous earth absorbent pads, it is necessary to mix quartz, pulp fiber, limestone powder, color paste and other materials with diatomaceous earth in proportion. After pressing, molding, drying, cutting, carving and other processes, a diatomaceous earth absorbent pad suitable for home use is finally formed. The diatomaceous earth absorbent pad is widely used in daily environments such as bathrooms, kitchens, and dining tables. Since the production process of diatomaceous earth absorbent pads requires contact with a lot of dusty environment, the cutting, adjustment and other steps will generate a lot of dust.

[0017] Drying: The diatomaceous earth pad continues to move forward to the wind knife, at which time the wind knife blows out hot air to blow away the residual water droplets on the upper and lower surfaces of the diatomaceous earth pad; then the diatomaceous earth pad enters the drying area I, and the hot air blower blows hot air into the hot air channel between the drying cover and the inner cover through the hot air pipe; then the hot air is ejected from the air outlet on the inner cover, acting on the diatomaceous earth pad to dry it; when the diatomaceous earth pad is on the drying conveyor belt, it is lifted up by the supporting protrusion, and the hot air is blown upward from the drying hole to the bottom of the diatomaceous earth pad to dry the bottom of the diatomaceous earth pad;

[0018] Wastewater recycling: The cleaning water source enters the fine washing section, rinses the diatomaceous earth pad, and then falls into the fine washing water receiving tank through the fine washing sump, and then enters the filter roller net cylinder; the filter roller net cylinder rotates, and the impurities in the water are retained in the filter roller net cylinder, while the water passes through the filter roller net cylinder and flows into the rough washing water storage tank to be used for rough washing; and the impurities in the filter roller net cylinder enter the sewage section and fall into the mud receiving bin, waiting to be cleaned.

[0020] 1. The present invention can clean the dust on the surface of the diatomaceous earth mat through the cleaning area, drying area I and drying area II, and then dry the diatomaceous earth mat, so that the diatomaceous earth mat is clean and dry, which is conducive to subsequent packaging and sales.

[0021] 2. The cleaning area of ​​the present invention is divided into a rough washing section and a fine washing section. The rough washing section can quickly clean most of the dust on the surface of the diatom mat, while the fine washing section cleans the residual dust and dissolves the agglomerated dust, thereby ensuring the cleaning effect while saving water to a certain extent.

[0022] 3. The sewage recycling system of the present invention can recycle the sewage from the fine washing section and then discharge it into the rough washing section for use in rough washing, which can further save water and reduce production costs.

[0023] 4. The inner cover and the drying cover of the present invention jointly form a hot air channel, so that the hot air can fully and evenly act on the diatomaceous earth mat, thereby enhancing the drying effect.

[0024] 5. The drying conveyor belt of the present invention is provided with supporting protrusions and drying holes, which can make the diatomaceous earth mat suspended in the air, so that both the upper and lower surfaces thereof can be dried quickly. BRIEF DESCRIPTION OF THE DRAWINGS

10. The method for using the diatomaceous earth pad cleaning and drying device according to any one of claims 1 to 9, characterized in that: The following steps are involved: 1) Cleaning: the finished diatomaceous earth mat is placed in the feeding area (1), and the diatomaceous earth mat is fed into the rough washing section (9) by the feeding conveyor belt (34); the spray head (11) in the rough washing section (9) sprays water downwards to quickly wash away the dust on the diatomaceous earth mat; in the rough washing section (9), the water flow sprayed by the spray head (11) is relatively large, so as to quickly wash away most of the dust on the diatomaceous earth mat; then the diatomaceous earth mat enters the fine washing section (10), and at this time, the spray head (11) in the fine washing section (10) sprays water downwards to wash away the dust left over from the meal; in the fine washing section (10), the water sprayed by the spray head (11) is relatively fine, which is conducive to fully washing away the residual dust; the length of the fine washing section (10) is at least twice that of the rough washing section (9), so that the fine washing time of the diatomaceous earth mat in the fine washing section (10) is long, which is conducive to fully washing away the dust; 2) Drying: The diatomaceous earth pad continues to move forward to the wind knife (23), at which time the wind knife (23) blows out hot air to blow away the residual water droplets on the upper and lower surfaces of the diatomaceous earth pad; then the diatomaceous earth pad enters the drying area I (3), and the hot air blower (24) blows hot air into the hot air channel between the drying cover (26) and the inner cover (30) through the hot air pipe (25); then the hot air is ejected from the air outlet (31) on the inner cover (30) and acts on the diatomaceous earth pad to dry it; when the diatomaceous earth pad is on the drying conveyor belt (27), it is lifted up by the supporting protrusion (32), and the hot air is blown upward from the drying hole (33) to the bottom of the diatomaceous earth pad to dry the bottom of the diatomaceous earth pad; 3) Wastewater recycling: The cleaning water source enters the fine washing section (10), rinses the diatomaceous earth pad, passes through the fine washing water collection tank (16), and falls into the fine washing water receiving tank (17), and then enters the filter roller net cylinder (19); the filter roller net cylinder (19) rotates, and impurities in the water are retained in the filter roller net cylinder (19), while the water passes through the filter roller net cylinder (19) and flows into the rough washing water storage tank (7) to be used for rough washing; and the impurities in the filter roller net cylinder (19) enter the sewage section (20) and fall into the mud receiving bin (22) to be cleaned.
