Description

TECHNICAL FIELD

[0001] The utility model relates to garbage treatment equipment technical field, concretely is a kind of anaerobic screw press machine discharge port cleaning device for kitchen waste treatment. BACKGROUND

[0002] Kitchen waste is mainly derived from daily life of residents, food processing, catering services and unit catering activities, including waste vegetable leaves, leftovers, fruit peels, eggshells, tea dregs, bones and the like, and is commonly found in household kitchens, restaurants, hotels, canteens and markets. In order to ensure the smooth progress of anaerobic fermentation, dewatering treatment is required before processing such waste. In this process, the commonly used equipment is an anaerobic screw press machine (also known as a biogas residue dewatering machine or a screw dewatering machine), which works by pushing the waste to the extrusion area through a screw propeller, removing water by extrusion, and achieving solid-liquid separation.

[0003] The patent with the current publication number CN206201527U discloses a screw dewatering machine and a biogas residue dewatering device, which includes a housing, an inner filter cylinder and a screw shaft arranged inside the housing, a feed inlet, a liquid outlet and a residue outlet outside the housing, and a working section in the form of a cone or a conical frustum on the screw shaft. When the material to be dewatered enters the space between the inner filter cylinder and the screw shaft from the feed inlet, the inner filter cylinder and the screw shaft can extrude the material, and the liquid produced after the material is extruded can be discharged from the liquid outlet, and the residue produced after the material is extruded can be discharged from the residue outlet. The screw dewatering machine and the biogas residue dewatering device have a simple structure, low manufacturing and operating costs, reduced investment costs for waste treatment plants, reduced operating energy consumption, and can bring good economic benefits.

[0004] However, the screw press machine in the above-mentioned technology still has the following problems: when the material is gradually pushed and extruded to the residue outlet, it is dewatered due to extrusion, and the density increases, which may cause the material to form lumps in the cavity at the end of the residue outlet. This lumping phenomenon can hinder the smooth discharge of the residue from the outlet, and further cause the blockage of the discharge port. Such blockage not only reduces the operating efficiency of the equipment, but in severe cases can even cause the equipment to stop. UTILITY MODEL CONTENTS

[0025] As shown in the utility model, the anaerobic screw press discharge port cleaning device for kitchen waste treatment is similar in structure to the prior art, such as the spiral dewatering machine and biogas residue dewatering equipment disclosed in the patent with the publication number CN206201527U, the main improvement of the utility model lies in avoiding the blockage of the screw press residue outlet and improving the stability of the screw press residue discharge, such as Figures 1 to 3 As shown in the utility model, the anaerobic screw press discharge port cleaning device for kitchen waste treatment is similar in structure to the prior art, such as the spiral dewatering machine and biogas residue dewatering equipment disclosed in the patent with the publication number CN206201527U, the main improvement of the utility model lies in avoiding the blockage of the screw press residue outlet and improving the stability of the screw press residue discharge, such as

[0026] As shown in the utility model, the anaerobic screw press discharge port cleaning device for kitchen waste treatment is similar in structure to the prior art, such as the spiral dewatering machine and biogas residue dewatering equipment disclosed in the patent with the publication number CN206201527U, the main improvement of the utility model lies in avoiding the blockage of the screw press residue outlet and improving the stability of the screw press residue discharge, such as Figure 2 and Figure 3 As shown in the utility model, the anaerobic screw press discharge port cleaning device for kitchen waste treatment is similar in structure to the prior art, such as the spiral dewatering machine and biogas residue dewatering equipment disclosed in the patent with the publication number CN206201527U, the main improvement of the utility model lies in avoiding the blockage of the screw press residue outlet and improving the stability of the screw press residue discharge, such as

[0027] As shown in the utility model, the anaerobic screw press discharge port cleaning device for kitchen waste treatment is similar in structure to the prior art, such as the spiral dewatering machine and biogas residue dewatering equipment disclosed in the patent with the publication number CN206201527U, the main improvement of the utility model lies in avoiding the blockage of the screw press residue outlet and improving the stability of the screw press residue discharge, such as Figures 2 to 4As shown, the anti-clogging cleaning assembly includes a cleaning motor 6 and an auger 7. The cleaning motor 6 is embedded inside the base 5. The output end of the cleaning motor 6 passes through one end of the discharge chute 501 near the extrusion discharge trough 401 and is fixedly connected to one end of the auger 7. The other end of the auger 7 passes through the discharge chute 501 and extends into the extrusion discharge trough 401. When the cleaning motor 6 is started, the auger 7 rotates within the extrusion discharge trough 401, thereby gradually guiding the slag in the extrusion discharge trough 401 into the discharge chute 501 through the rotating auger 7, which can prevent the slag from being squeezed into the extrusion discharge trough 401 and causing blockage.

[0028] like Figures 2 to 5 As shown, a reinforcing rod 8 is movably connected to the end of the auger 7 furthest from the cleaning motor 6. The other end of the reinforcing rod 8 extends upward and is fixedly connected to the extrusion discharge trough 401. The reinforcing rod 8 provides support between the end of the auger 7 and the extrusion discharge trough 401, preventing the slag material squeezed by the screw press body 1 into the extrusion discharge trough 401 from being squeezed into the end of the auger 7, causing the auger 7 to bend and deform, thus improving the stability of the auger 7 during rotation.

[0029] like Figures 2 to 5 As shown, a conical block 9 is fixedly connected to one end of the reinforcing rod 8 near the auger 7. A groove 901 is formed at the larger end of the conical block 9, and a rotating block 10 is rotatably connected within the groove 901. The rotating block 10 is fixedly connected to the end of the auger 7 furthest from the cleaning motor 6. The rotation between the groove 901 at the bottom of the conical block 9 and the rotating block 10 ensures that the reinforcing rod 8 continuously provides support to the auger 7 during its rotation. Simultaneously, when the slag is squeezed onto the conical block 9, the sharp tip at the top of the conical block 9 prevents slag from caking and clogging at the top.

[0030] like Figures 2 to 5 As shown, the reinforcing rod 8 has symmetrical inclined surfaces on both sides of its upward-facing end. When the slag is squeezed onto the reinforcing rod 8, the symmetrical inclined surfaces at the top can cut the slag to both sides, thereby preventing the slag from accumulating and clumping above the reinforcing rod 8.

[0031] like Figure 1 and Figure 2 As shown, the extrusion discharge trough 401 is inclined and funnel-shaped, with the larger end connected to the screw press body 1 and the smaller end connected to the discharge chute 501. The auger 7 is arranged parallel to the inclined surface of the extrusion discharge trough 401. After the slag is extruded from the screw press body 1 into the extrusion discharge trough 401, it can gradually gather towards the position of the auger 7 through the inclined extrusion discharge trough 401 and be carried out by the rotating auger 7, thereby improving the slag discharge efficiency.

[0032] 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.
