Description

Technical Field

[0001] This utility model relates to the field of fertilizer production technology, and in particular to a dehydration device for producing odorless biochar-based organic fertilizer. Background Technology

[0002] In agricultural production, biochar-based organic fertilizers have been applied to various crops, such as vegetables, fruits, and grains. In vegetable cultivation, they can improve yield and quality, and reduce the occurrence of pests and diseases. In fruit tree cultivation, they help improve the taste and color of fruits, increase sugar content, and enhance storage resistance. Biochar-based organic fertilizers are usually in granular form and require dehydration during the preparation process.

[0003] Existing dehydration equipment for biochar-based organic fertilizer production has some shortcomings. Drying equipment dries granular biochar-based organic fertilizer by heating and evaporating the moisture in the material, which is then carried away by airflow, thus achieving dehydration and drying. However, continuous drying may affect the beneficial components and microbial activity in biochar-based organic fertilizer.

[0004] To address these issues, those skilled in the art have proposed a dehydration device for the production of odorless biochar-based organic fertilizer. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problem that the continuous drying process in the above or existing technologies may affect the beneficial components and microbial activity in biochar-based organic fertilizers, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a dehydration device for the production of odorless biochar-based organic fertilizer.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a dehydration device for producing odorless biochar-based organic fertilizer, comprising a U-shaped frame, wherein a pressing mechanism is provided on the top of the U-shaped frame;

[0009] A filter press assembly is installed inside the U-shaped frame and is adapted to the pressing mechanism;

[0010] A shielding mechanism is installed on both sides of the U-shaped frame. The U-shaped frame, the filter press assembly, and the shielding mechanism form an enclosed space to assist in the dewatering process.

[0011] A drying mechanism, which is mounted on a U-shaped frame.

[0012] As a preferred embodiment of the dehydration device for producing odorless biochar-based organic fertilizer of this utility model, the pressing mechanism is located in the middle below the drying mechanism, and includes a hydraulic cylinder. A pressure plate is installed at the bottom end of the output shaft of the hydraulic cylinder, and the two sides of the pressure plate are chamfered.

[0013] As a preferred embodiment of the dehydration device for producing odorless biochar-based organic fertilizer of this utility model, the filter press assembly is located below the pressure plate and includes a tray, side plates and vertical plates fixed on both sides of the tray, and a first screen, an activated carbon mesh, a second screen, and a filter cloth covering the surface of the second screen are stacked sequentially inside the tray.

[0014] As a preferred embodiment of the dehydration device for producing odorless biochar-based organic fertilizer of this utility model, the shielding mechanism includes an electric slide rail, which is vertically installed on both sides of the U-shaped frame. A slider is slidably engaged on the outer wall of the electric slide rail, and a baffle is installed at one end of each of the two sliders. The outer walls of the two sides of the baffle are attached to the inner wall of the U-shaped frame.

[0015] As a preferred embodiment of the dehydration device for producing odorless biochar-based organic fertilizer of this utility model, a guide plate is fixedly installed on the top outer wall of each of the two vertical plates, and the other end of the guide plate is attached to the inner wall of the U-shaped frame.

[0016] As a preferred embodiment of the dehydration device for producing odorless biochar-based organic fertilizer of this utility model, the drying mechanism is fixedly installed on the top of the U-shaped frame, including a hot air box and an air outlet pipe communicating with the hot air box, and the air outlet end of the air outlet pipe extends into the interior of the U-shaped frame.

[0017] As a preferred embodiment of the dehydration device for producing odorless biochar-based organic fertilizer of this utility model, wherein: a fixing plate is horizontally installed on both sides of the inner wall of the U-shaped frame near the lower position, and a water collection tank is installed on the surface of the fixing plate.

[0018] The beneficial effects of this odorless biochar-based organic fertilizer production dehydration device are as follows: Granular biochar-based organic fertilizer is pressed into the filter press assembly by a pressure plate. During pressing, the particles can withstand pressure relatively stably, and water is more easily squeezed out from the gaps between the particles under pressure, thus achieving dehydration. The activated carbon mesh adsorbs odors, deodorizing the biochar-based organic fertilizer. Then, a drying mechanism is used for brief drying, thus avoiding an excessively long drying process and preventing damage to the beneficial components and microbial activity in the biochar-based organic fertilizer.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Reference Figures 1 to 3 This is the first embodiment of the present utility model. This embodiment provides a dehydration device for the production of odorless biochar-based organic fertilizer, which can achieve dehydration by pressure filtration and deodorization by adsorbing odors. It includes a U-shaped frame 100, and a pressing mechanism 300 is provided on the top of the U-shaped frame 100.

[0028] The filter press assembly 600 is installed inside the U-shaped frame 100 and is compatible with the pressing mechanism 300.

[0029] A shielding mechanism 500 is installed on both sides of the U-shaped frame 100. The U-shaped frame 100, the filter press assembly 600, and the shielding mechanism 500 form a closed space to assist in the dewatering process; and,

[0030] Drying mechanism 200 is mounted on U-shaped frame 100.

[0031] In use, the shielding mechanism 500 is lowered to place the granular biochar-based organic fertilizer inside the filter press assembly 600. Then, the shielding mechanism 500 is raised to start the pressing mechanism 300. The pressing mechanism 300 is lowered and pressed into the filter press assembly 600 to dehydrate the biochar-based organic fertilizer through filtration. Then, the pressing mechanism 300 is raised to start the drying mechanism 200 to dry the fertilizer and absorb the odor of the biochar-based organic fertilizer through the filter press assembly 600.

[0032] As an optional embodiment, refer to Figure 1 and Figure 4 The pressing mechanism 300 is located in the middle below the drying mechanism 200, and includes a hydraulic cylinder 301. A pressure plate 302 is installed at the bottom end of the output shaft of the hydraulic cylinder 301, and the two sides of the pressure plate 302 are chamfered.

[0033] The hydraulic cylinder 301 is activated to move the pressure plate 302 downward, thereby cooperating with the filter press assembly 600 to perform filter press dehydration of the biochar-based organic fertilizer. The chamfers on both sides of the pressure plate 302 help to guide the hot air blown out by the drying mechanism 200, which facilitates further dehydration of the biochar-based organic fertilizer and makes its dehydration more complete.

[0034] Furthermore, the filter press assembly 600 is located below the pressure plate 302 and includes a tray 601, side plates 602 and vertical plates 603 fixed to both sides of the tray 601. Inside the tray 601, a first screen 604, an activated carbon mesh 605, a second screen 606, and a filter cloth 607 covering the surface of the second screen are stacked in sequence.

[0035] The activated carbon mesh 605 of the filter press assembly 600 has a detachable honeycomb structure and is filled with coconut shell activated carbon particles, which facilitates the adsorption of odors from biochar-based organic fertilizer and performs deodorization. Through the obstruction of the first screen 604, the second screen 606, and the filter cloth 607, the biochar-based organic fertilizer is prevented from falling below while dehydrating.

[0036] Furthermore, the shielding mechanism 500 includes an electric slide rail 501, which is vertically installed on both sides of the U-shaped frame 100. Slider 502 is slidably engaged on the outer wall of the electric slide rail 501. The same baffle 503 is installed at one end of the two sliders 502, and the outer walls of the baffle 503 are attached to the inner wall of the U-shaped frame 100.

[0037] When in use, starting the electric slide rail 501 will drive the slider 502 to slide, thereby causing the baffle 503 to move up and down.

[0038] As an optional embodiment, refer to Figure 3 Guide plates 400 are fixedly installed on the top outer walls of the two vertical plates 603, and the other end of the guide plates 400 is attached to the inner wall of the U-shaped frame 100.

[0039] The guide plate 400 can guide the hot air blown out by the drying mechanism 200, so that the hot air enters the interior of the filter press assembly 600, thereby facilitating the drying of biochar-based organic fertilizer.

[0040] Furthermore, the drying mechanism 200 is fixedly installed on the top of the U-shaped frame 100, including a hot air box 201 and an air outlet pipe 202 communicating with the hot air box 201, with the air outlet end of the air outlet pipe 202 extending into the interior of the U-shaped frame 100.

[0041] The hot air box 201 is equipped with a heating copper pipe and a fan. The hot air is heated by the heating copper pipe and blown by the fan through the air outlet pipe 202 to the biochar-based organic fertilizer inside the filter press assembly 600 for secondary dehydration.

[0042] Furthermore, fixing plates 700 are horizontally installed on both sides of the inner wall of the U-shaped frame 100 near the bottom, and water collection troughs 701 are installed on the surface of the fixing plates 700.

[0043] The water produced during the filter press process falls into the water collection tank 701, which collects the water produced during the dehydration process.
