Description

Technical Field

[0001] This utility model belongs to the field of high-temperature aerobic fermentation technology, specifically relating to a material discharge structure for a vertical aerobic fermenter. Background Technology

[0002] Vertical high-temperature aerobic fermentation tanks utilize blower aeration, heat preservation, and microbial activity to biologically decompose and mature organic matter such as manure, kitchen waste, and garden waste, transforming organic waste into organic fertilizer raw materials. These raw materials are then aged and processed into organic fertilizers to meet market demands. Currently, most vertical high-temperature aerobic fermentation tanks on the market have an opening formed on the base, sealed by a baffle plate. A hydraulic cylinder drives the baffle plate in a linear or rotary reciprocating motion to open the opening, allowing the material to slide down under its own weight. However, this often results in lumps that accumulate at the outlet, causing blockages and requiring manual intervention, which is time-consuming and labor-intensive. Furthermore, the baffle plate slides on a track, and both the baffle plate and the track are steel structures, resulting in high pushing resistance and noise during operation. Additionally, the baffle plate lacks limit switches, causing impact to the baffle plate and hydraulic cylinder when the cylinder pushes or pulls it to the end point, affecting their lifespan. Summary of the Invention

[0003] The purpose of this utility model is to provide a discharge structure for vertical aerobic fermenters, which mainly solves the problems of material blockage at the outlet, high noise, and lack of limiting of the insert plate in the existing discharge structure of fermenters.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a feeding structure for a vertical aerobic fermenter, comprising a plate, a cylinder, a frame, and a guide rail. The frame is provided at the material outlet at the bottom of the fermenter, and the guide rail is fixed on the frame. The movable end of the cylinder is connected to the plate, and the fixed end is connected to the frame. The plate is inserted into the guide rail. Based on the prior art, this utility model further improves upon the following: the feeding structure also includes rake teeth, a slide, and a limiting device. The rake teeth are fixed on the side of the plate that contacts the material. The slide is located within the guide rail, and the plate is inserted into the slide. A limiting device is provided at the starting and ending positions of the plate.

[0005] Preferably, the fermenter also includes blades, which are fixed on the upper plate at the bottom of the fermenter and on both the front and rear sides of the discharge port.

[0006] Preferably, the rake teeth are fixed to the front side of the insert plate and are arranged offset from the blades.

[0007] Preferably, the number of rake teeth is not less than 5, and the spacing between the rake teeth is not greater than 100mm.

[0008] Preferably, the slide is L-shaped, and the length of the guide rail and the slide is 1.5-2 times the stroke of the insert plate.

[0009] Preferably, the limiting device includes two proximity switch mounting bases, two proximity switches, and a sensing plate. The two proximity switch mounting bases are fixed on the frame, and one proximity switch is fixed on each of the two proximity switch mounting bases. The insert plate is connected to the sensing plate.

[0010] Preferably, the limiting device further includes a connecting rod, and the insert plate is connected to the sensing plate via the connecting rod.

[0011] Preferably, the positions of the two proximity switch mounting bases can be adjusted along the movement direction of the insert plate.

[0012] Preferably, the end of the insert plate is provided with a cylinder connecting seat, which is connected to the movable end of the cylinder by a pin.

[0013] Preferably, a cylinder tailstock is fixed on the frame, and the fixed end of the cylinder is connected to it by a pin.

[0014] The beneficial effects of this utility model are:

[0015] 1. The rake teeth at the front end of the insert plate break up the organic fertilizer material and work with the blades at the discharge port of the upper plate to cut larger pieces of organic fertilizer material, which facilitates the smooth flow of organic fertilizer material and reduces discharge time and manual intervention.

[0016] 2. By setting up slides, the bottom and sides of the insert plate are in contact with the slides, which reduces the resistance to the reciprocating motion of the insert plate and reduces the noise generated by sliding with the steel structure. At the same time, the length of the track and nylon slide is 1.5 to 2 times the stroke of the insert plate, which reduces the force on the insert plate in the vertical direction and increases the stability of the insert plate.

[0017] 3. The travel of the plug plate is limited by the proximity switch, which avoids the plug plate hitting the base due to overtravel and reduces the impact force on the plug plate and the hydraulic cylinder. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] As attached Figure 1-5 As shown, this embodiment provides the following technical solution:

[0028] A material discharge structure for a vertical aerobic fermenter includes a slide plate 1, a hydraulic cylinder 2, a frame 3, a guide rail 4, rake teeth 5, a slide rail 6, and a limiting device 7. A rectangular outlet 9 is opened on a flat plate 8 at the bottom of the fermenter. The lower part of the outlet 9 is welded to the frame 3, which consists of a front beam 31, a rear beam 32, a left beam 33, and a right beam 34. The guide rail 3 is fixed on the left beam 33 and the right beam 34 of the frame 3. The front beam 31 can act as a blocking plate to prevent material from flowing out from the front end of the slide plate 1. The movable end of the hydraulic cylinder 2 is connected to the slide plate 1, and the fixed end is connected to the right beam 34 of the frame 3. The rake teeth 5 are fixed on the side of the slide plate 1 that contacts the material. The slide rail 6 is set inside the guide rail 4, and the slide plate 1 is inserted into the slide rail 6. The limiting device 7 is provided at the starting and ending positions of the slide plate 1. The rake teeth 5 are inserted into the organic fertilizer. Driven by the reciprocating motion of the hydraulic cylinder 2, the insert plate 1 reciprocates, thereby driving the rake teeth 5 to break up the material and prevent the material from clogging the discharge port 9. The slide 6 is made of nylon or other self-lubricating material to reduce the friction of the reciprocating motion of the insert plate 1 and reduce noise. By setting the limiting device 7, the insert plate 1 can stop moving when it reaches the starting position and the ending position, which plays a limiting role.

[0029] Furthermore, to further chop larger pieces of material, the feeding structure in this embodiment also includes blades 10. Blades 10 are fixed on the upper plate 8 at the bottom of the fermentation tank and on both the front and rear sides of the discharge port 9, with no fewer than 12 blades 10. When encountering larger pieces of material, the rake teeth 5 and the blades 10 break up the raw material, thereby accelerating the discharge and preventing the organic fertilizer raw material from clogging at the discharge port 9.

[0030] In a preferred embodiment of this invention, the rake teeth 5 are fixed to the front side of the insert plate 1. When the insert plate 1 moves, the rake teeth 5 are staggered from the blades 10 to avoid collision between them. The number of rake teeth 5 is not less than 5, and the distance between the rake teeth 5 is not greater than 100mm.

[0031] In order to reduce the friction between the insert plate 1 and the guide rail 4, as a preferred embodiment of this invention, the slide 6 is L-shaped. Thus, the lower plane of the insert plate 1 in contact with the guide rail 4 and the left and right sides are equipped with slides 6, which reduces the frictional resistance of the reciprocating motion of the insert plate 1 and the noise generated by sliding with the steel structure. In this embodiment, the length of the guide rail 4 and the slide 6 is 1.5-2 times the stroke of the insert plate 1.

[0032] In a preferred embodiment of this invention, the limiting device 7 includes two proximity switch mounting seats 71, two proximity switches 72, a sensing plate 73, and a connecting rod 74. The two proximity switch mounting seats 71 are fixed to the rear beam 32 of the frame 3. One proximity switch mounting seat 71 is positioned at the starting position of the insert plate 1, and the other proximity switch mounting seat 71 is positioned at the ending position of the insert plate 1. One proximity switch 72 is fixed to each of the two proximity switch mounting seats 71. The insert plate 1 is connected to the sensing plate 73 via the connecting rod 74. When the insert plate 1 reciprocates, the proximity switch 72 on the proximity switch mounting seat 71 senses the signal from the sensing plate 73, causing the hydraulic cylinder 2 to stop working at the starting and ending positions. This prevents the insert plate 1 from colliding with the frame 3 when pushed to its limit position, thus avoiding impact on the insert plate 1 and the hydraulic cylinder 2, protecting the insert plate 1 and the hydraulic cylinder 2, and extending their service life.

[0033] As a preferred embodiment of this invention, the positions of the two proximity switch mounting bases 71 can be adjusted along the movement direction of the insert plate 1, which facilitates on-site adjustment of the position of the proximity switch 72 to ensure it is in a reasonable position.

[0034] To facilitate the connection between the insert plate 1 and the hydraulic cylinder 2, in a preferred embodiment of this invention, the end of the insert plate 1 is fixedly connected to a hydraulic cylinder connecting seat 11, and the hydraulic cylinder connecting seat 11 is connected to the movable end of the hydraulic cylinder 2 by a pin.

[0035] To facilitate the connection between the hydraulic cylinder 2 and the frame 3, in a preferred embodiment of this invention, a hydraulic cylinder tailstock 12 is fixed on the rear beam 32 of the frame 3, and the hydraulic cylinder tailstock 12 is connected to the fixed end of the hydraulic cylinder 2 by a pin.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
