DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0038] Embodiment 1:

[0039] like Figures 1 to 9 As shown, the spiral filter provided in this embodiment includes a tank body 1, a filter plate 2, an upper shell 3, a lower shell 4 and a feed hopper 5, wherein:

[0040] The trough body 1 is a container with an opening at the top, and a vertical partition 11 is arranged inside the trough body 1. The inner cavity of the trough body 1 is divided into a disconnected water storage chamber 12 and a slag storage chamber 13 by the partition 11. The water storage chamber 12 is located to store the liquid separated from the slag liquid, and the slag storage chamber 13 is used to store the solid matter separated from the slag liquid. It should be noted that the solid matter is a granular solid, not a long strip solid.

[0041] The filter plate 2, the upper shell 3 and the lower shell 4 are all spiral-shaped, and the upper shell 3 and the lower shell 4 are adapted to the filter plate 2. The bottom end of the filter plate 2 is integrally formed or welded with a connecting plate 21, and the connecting plate 21 is detachably fixedly connected to the partition 11, so that the filter plate 2 is installed on the partition 11, and the filter plate 2 is located above the tank body 1. The upper shell 3 and the lower shell 4 are both connected to the filter plate 2. The upper shell 3 is located above the filter plate 2, and the lower shell 4 is located below the filter plate 2. The upper shell 3, the filter plate 2 and the lower shell 4 in this embodiment form a spiral pipeline.

[0042] Specifically, the upper shell 3 and / or the lower shell 4 are connected to the filter plate 2 by bolting, or by tying with a band. Of course, a buckle can be provided at the edge of the filter plate 2, and a slot can be provided at the upper shell 3 and the lower shell 4. The upper shell 3 and the lower shell 4 can be installed on the filter plate 2 by the snap-fitting of the buckle and the slot. In addition, a sealing gasket is provided at the position where the upper shell 3 contacts the filter plate 2 and the position where the lower shell 4 contacts the filter plate 2, so as to avoid water leakage at the contact position. The above-mentioned installation method is a detachable installation. Of course, the upper shell 3 and the lower shell 4 can also be fixedly installed on the filter plate 2 by welding.

[0043] A slag channel 31 is formed between the upper shell 3 and the filter plate 2, and a water channel 41 is formed between the lower shell 4 and the filter plate 2. In this way, the slag channel 31 is actually located above the water channel 41, and the bottom end of the slag channel 31 is connected to the slag storage chamber 13, and the bottom end of the water channel 41 is connected to the water storage chamber 12. The feed hopper 5 is connected to the top of the slag channel 31, so as to facilitate the introduction of slag liquid into the slag channel 31.

[0044] When in use, the slag liquid is introduced from the above-mentioned feed hopper 5 into the above-mentioned slag channel 31, and the slag liquid at this time falls on the above-mentioned filter plate 2, and the liquid passes through the filter plate 2 into the water channel 41, while the solid matter stays on the filter plate 2 and is located in the slag channel 31. Since the filter plate 2, the upper shell 3 and the lower shell 4 are all spiral structures, the above-mentioned water channel 41 and the slag channel 31 are both spiral flow channels. The solid matter in the slag channel 31 will slide along the slag channel 31 under the action of its own gravity, and finally enter the slag storage cavity 13 of the tank body 1 from the opening at the bottom end of the slag channel 31, and the liquid in the water channel 41 will slide along the water channel 41 under the action of its own gravity, and finally enter the water storage cavity 12 of the tank body 1 from the opening at the bottom end of the water channel 41, thereby separating the solid matter and the liquid.

[0045] Through the above structure, the spiral filter provided by this embodiment cleverly uses gravity to make the slag liquid automatically fall in the spiral channel, and completes the separation of slag and liquid during the falling process, and does not need to set a auger shaft and a motor, which is low in cost, light in weight, simple and convenient to use, and the overall structure is simple and compact. When the upper shell 3 and the lower shell 4 are both detachably mounted on the filter plate 2, if the slag channel 31 or the water channel 41 is blocked, it is only necessary to remove the upper shell 3 or the lower shell 4 from the casing for convenient cleaning. Therefore, the spiral filter also has the advantage of being easy to maintain.

[0046] More preferably, the bottom wall of the lower shell 4 in this embodiment is provided with a boss 42 located outside the water channel 41, a plug 43 is provided on the boss 42, a water hole penetrating the boss 42 and connected to the water channel 41 is provided in the plug 43, a platform 14 is provided on one side wall of the partition 11 close to the water storage chamber 12, a water hole is provided on the platform 14, and a ring 15 surrounding the water hole is provided on the top surface of the platform 14, a hard pipe 6 is provided between the platform 14 and the boss 42, the plug 43 is inserted at the top end of the hard pipe 6, and the bottom end of the hard pipe 6 is inserted in the ring 15. In this way, the hard pipe 6 not only connects the water hole and the water hole, but also supports the entire spiral pipeline (that is, the pipeline composed of the upper shell 3, the lower shell 4 and the filter plate 2). It should be noted that the number of the above-mentioned hard tubes 6 is one or more. In this embodiment, the number of the hard tube 6 is one for illustration. When the number of the hard tubes 6 is more than one, the multiple hard tubes 6 are sequentially arranged along the direction of the spiral pipeline, so that the multiple hard tubes 6 are sequentially connected to the path of the water channel 41. The lower ends of the hard tubes 6 and the water channel 41 can guide the liquid in the water channel 41 into the water storage chamber 12 at different positions. In this way, it can be avoided that the liquid in the water channel 41 is too much, resulting in untimely water discharge and the liquid in the pipeline immersing the solids in the slag channel 31.

[0047] Preferably, a cloth bag 7 can be detachably mounted on the partition 11, and the cloth bag 7 is located in the water storage chamber 12 and is suspended in the air. The bottom end of the water channel 41 and the water flow hole on the platform 14 are both located directly above the mouth of the cloth bag 7, so that the liquid coming out of the bottom end of the water channel 41 and the liquid left by the water flow hole will fall directly into the cloth bag 7, so that the cloth bag 7 is used to filter the liquid entering the water storage chamber 12 again to filter out fine particles in the liquid. When there are a lot of filtered materials in the cloth bag 7, the cloth bag 7 can be removed from the partition 11 for replacement and cleaning.

[0048] Optionally, a steel ring 71 for support is provided at the mouth of the cloth bag 7, that is, the steel ring 71 opens the mouth of the cloth bag 7, and the steel ring 71 is connected with a stud 72, which is located outside the cloth bag 7. A through hole is provided on the partition 11, and the stud 72 passes through the through hole and is screwed with a first nut 73, so that the cloth bag 7 can be detachably mounted on the partition 11. A screw 22 is provided on one side of the connecting plate 21 close to the lower shell 4, and a through hole is provided on the partition 11. The screw 22 passes through the through hole and is screwed with a second nut 23, so that the connecting plate 21 can be detachably fixedly connected to the partition 11.

[0049] An optional implementation of this embodiment is as follows: a guide ramp plate 8 is installed in the above-mentioned slag storage chamber 13, and the bottom end of the slag channel 31 is placed directly above the top of the guide ramp plate 8, so that the solids falling from the bottom end of the slag channel 31 will fall on the top of the guide ramp plate 8, and the bottom of the guide ramp plate 8 overlaps the bottom of the tank body 1, and then flows down along the guide ramp plate 8 to the slag storage chamber 13 in the tank body 1. The setting of the guide ramp plate 8 can effectively prevent the solids flowing out of the slag channel 31 from accumulating somewhere in the slag storage chamber 13.

[0050] Optionally, a rotating shaft 81 is provided at both ends of the material guide ramp plate 8, the two rotating shafts 81 are coaxially arranged, a circular hole is provided at the two opposite side walls of the slag storage chamber 13, and the two rotating shafts 81 are respectively rotatably inserted in the two circular holes, so that the material guide ramp plate 8 can rotate in the slag storage chamber 13. A rotating driving member 9 is also installed on the outer side wall of the tank body 1, and the rotating driving member 9 is connected to one of the rotating shafts 81, and the rotating driving member 9 is used to drive the material guide ramp plate 8 to rotate in the slag storage chamber 13. With the help of the rotating drive member 9, the user can drive the above-mentioned material guide ramp 8 to swing around the rotating shaft 81 in the slag storage chamber 13, so as to facilitate shaking off the solid matter on the guide ramp. Of course, during specific use, workers are also required to regularly scrape the solid matter accumulated in the slag storage chamber 13 and distribute it in the slag storage chamber 13, and when a lot of solid matter accumulates in the slag storage chamber 13, the guide ramp can be turned vertically to free up space in the slag storage chamber 13 for storing more solid matter.

[0051] Specifically, the above-mentioned rotary drive member 9 includes a crank, one end of which is sleeved on the above-mentioned rotating shaft 81 and linked with the rotating shaft 81. The user only needs to crank the crank to drive the guide ramp to rotate. A convex tube 16 is provided on the outer wall of the tank body 1, and the crank is provided with a telescopic rod 91. When the guide ramp 8 is turned vertically, the telescopic rod 91 is inserted into the convex tube 16 to lock it. Of course, the above-mentioned rotary drive member 9 can also be an electric motor.

[0052] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
