Technical Field

[0001] The present invention relates to the technical field of kitchen waste treatment, and in particular to a limit feed detection device, a fermentation bin and kitchen waste treatment equipment. Background Art

[0002] Due to the high temperature, high humidity, high oil content, and high dust content in the horizontal fermentation bin, and the presence of a stirring shaft in the bin, there is no dead angle for stirring in the bin, the sensor installation environment is harsh, the equipment has large vibrations during operation, and the state of the material in the bin will present different material states in different processing cycles (fluid or semi-fluid in the early stage, powdered solid in the later stage). The existing material inspection devices or sensors on the market have the following problems:

[0003] 1. The stirring action of the stirring blade will affect the detection of the sensor and easily cause misjudgment;

[0004] 2. Not waterproof or the sensor is easily contaminated by water or oil, which affects the detection accuracy and is prone to failure;

[0005] 3. The sensor is easily covered with dust in a short period of time and is prone to failure;

[0006] 4. The stirring blades can easily cause irreversible damage to the sensor;

[0007] 5. The use of radar or infrared material sensors is costly and cannot be contaminated with oil, water or dust, and is easily disturbed by the stirring blades.

[0008] In view of this, a limit feeding detection device, a fermentation bin and kitchen waste treatment equipment are proposed. Summary of the invention

[0009] The purpose of the present invention is to provide a limit feed detection device, a fermentation bin, and kitchen waste treatment equipment to solve the problems pointed out in the background technology.

[0010] The above technical objectives of the present invention are achieved through the following technical solutions:

[0011] A limit feed detection device includes a cylinder body, a connecting rod, an alarm triggering device, an alarm, a piston plate, a piston ball and a spring. The cylinder body is arranged in a tubular shape. The cylinder body has a near-bin end and a far-bin end. The near-bin end is connected to the side of the bin body of the fermentation bin. The piston plate is arranged in the cylinder body and is arranged perpendicular to the length direction of the cylinder body. One end of the connecting rod is connected to the piston plate, and the other end passes through the piston ball and then passes out through the far-bin end of the cylinder body. The spring is sleeved on the connecting rod, one end of which is connected to the piston ball, and the other end is connected to the far-bin end of the cylinder body. The piston ball is a hollow structure. The alarm triggering device is arranged on the extension line of the connecting rod for receiving the action signal of the connecting rod. The alarm is electrically connected to the alarm triggering device.

[0012] In a preferred embodiment, the alarm triggering device is configured as a travel switch.

[0013] In a preferred embodiment, it further comprises a mounting plate, on which an opening and a plurality of fixing through holes are provided, wherein the opening is connected to the near-bin end of the cylinder body, and the fixing through holes are used for bolt fixing.

[0014] In a preferred embodiment, it further comprises a sliding block and a sliding seat, wherein the sliding block is arranged on the sliding seat and can slide on the sliding seat.

[0015] In a preferred embodiment, it further comprises a carrier plate, and the slide seat and the alarm triggering device are arranged on the carrier plate.

[0016] In a preferred embodiment, the piston plate includes a plate body, a fixing ring and filter paper, the connecting rod is connected to the plate body, a plurality of water-permeable holes are provided on the plate surface of the plate body, the fixing ring is provided with a magnet for adsorbing the plate body, the fixing ring is adsorbed on the plate body, and the filter paper is pressed on the plate body.

[0017] In a preferred embodiment, an annular groove is provided on the edge of the plate body, and an extended edge is provided on the fixing ring, and the extended edge surrounds the annular groove.

[0018] In a preferred embodiment, the fixing ring is provided with a plurality of cutting teeth distributed along its edge, the cutting teeth are arranged at an angle, a mounting hole is provided on the plate body, a bearing is provided in the mounting hole, the connecting rod is connected to the bearing, a limit block is provided in the annular groove, and a limit groove matching the limit block is provided on the fixing ring.

[0019] A fermentation bin comprises the above-mentioned limit feed detection device.

[0020] A kitchen waste treatment device comprises the fermentation bin.

[0021] Compared with the prior art, the present invention provides a limit feed detection device. During operation, when the material in the fermentation bin reaches the piston plate, the piston plate contacts the material and compresses the air in the bin, causing the far bin end of the piston plate cylinder to move. Driven by the gravity and pressure of the material, the piston plate moves from the near bin end to the far bin end inside the cylinder, pushing the piston ball to move inside the cylinder, thereby pushing the spring to compress and deform. After the spring is compressed and deformed, it pushes the connecting rod to hit the alarm trigger device. After the alarm trigger device receives the collision information of the connecting rod, the alarm trigger device generates an alarm signal, triggers the alarm to start the alarm reminder, and provides information to the garbage disposal center.

[0022] On the contrary, when the material in the fermentation bin moves away from the piston plate, the pressure on the piston plate disappears, causing the piston plate to move into the bin, causing the compression deformation of the spring in the cylinder body to disappear, generating an outward thrust, causing the piston plate to move from the far bin end to the near bin end inside the cylinder body under the push of the spring elastic force recovery, and eventually causing the connecting rod to move away from the alarm trigger device. After the alarm trigger device receives the information that the slider is away, the alarm trigger device generates an alarm signal, triggering the alarm to start the alarm reminder, and providing information to the garbage disposal center.

DETAILED DESCRIPTION

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0035] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0036] like Figures 1 to 5 As shown, a limit feed detection device includes a cylinder body 1, a connecting rod 4, an alarm trigger device 5, an alarm 6, a piston plate 7, a piston ball 19 and a spring 20. The cylinder body 1 is configured to be tubular, and the cylinder body 1 has a near warehouse end 2 and a far warehouse end 3. The near warehouse end 2 is connected to the warehouse body side of the fermentation warehouse. The piston plate 7 is arranged in the cylinder body 1 and is arranged perpendicular to the length direction of the cylinder body 1. One end of the connecting rod 4 is connected to the piston plate 7, and the other end passes through the piston ball 19 and then passes out through the far warehouse end 3 of the cylinder body 1. The spring 20 is sleeved on the connecting rod 4, one end of which is connected to the piston ball 19, and the other end is connected to the far warehouse end 3 of the cylinder body 1. The piston ball 19 is a hollow structure. The alarm trigger device 5 is arranged on the extension line of the connecting rod 4 for receiving the action signal of the connecting rod 4. The alarm 6 is electrically connected to the alarm trigger device 5.

[0037] A limit feed detection device of the present embodiment, during operation, when the material in the fermentation bin reaches the piston plate 7, the piston plate 7 contacts the material and compresses the air in the bin, causing the far bin end 3 of the cylinder body 1 of the piston plate 7 to move. Driven by the gravity and pressure of the material, the piston plate 7 moves from the near bin end 2 to the far bin end 3 of the cylinder body 1 inside the cylinder body 1, pushing the piston ball 19 to move inside the cylinder body 1, thereby pushing the spring 20 to compress and deform. After the spring 20 is compressed and deformed, it pushes the connecting rod 4 to collide with the alarm trigger device 5. After the alarm trigger device 5 receives the collision information of the connecting rod 4, the alarm trigger device 5 generates an alarm signal, triggers the alarm 6 to start the alarm reminder, and provides information to the garbage disposal center.

[0038] On the contrary, when the material in the fermentation bin moves away from the piston plate 7, the pressure on the piston plate 7 disappears, causing the piston plate 7 to move into the bin, causing the compression deformation of the spring 20 in the cylinder body 1 to disappear, generating an outward thrust, causing the piston plate 7 to move from the far bin end 3 to the near bin end 2 of the cylinder body 1 inside the cylinder body 1 under the push of the elastic force recovery of the spring 20, and finally causing the connecting rod 4 to move away from the alarm trigger device 5. After the alarm trigger device 5 receives the information that the slider 24 is away, the alarm trigger device 5 generates an alarm signal, triggering the alarm 6 to start the alarm reminder, and providing information to the garbage disposal center.

[0039] Specifically, the alarm triggering device 5 is configured as a travel switch.

[0040] In order to achieve installation, a limit feed detection device of this embodiment also includes a mounting plate 21, on which an opening 22 and a plurality of fixing through holes 23 are provided. The opening 22 is connected to the near-bin end 2 of the cylinder body 1, and the fixing through holes 23 are used for bolt fixing. The mounting plate 21 is installed on the side wall of the fermentation bin by passing the bolts through the fixing through holes 23.

[0041] In order to enable the connecting rod 4 to accurately point to the travel switch, a limit feed detection device of this embodiment also includes a slider 24 and a slide seat (not shown in the drawings). The slider 24 is arranged on the slide seat and can slide on the slide seat. A stable guiding effect is achieved through the slide seat, so that the movement of the connecting rod 4 can accurately point to the travel switch.

[0042] In order to realize the installation of the slide seat and the alarm trigger device 5 , a limit feed detection device of this embodiment further includes a carrier plate 25 , and the slide seat and the alarm trigger device 5 are arranged on the carrier plate 25 .

[0043] Furthermore, the piston plate 7 includes a plate body 8, a fixing ring 14 and a filter paper 18, the connecting rod 4 connects the plate body 8, a plurality of water-permeable holes 9 are arranged on the plate surface of the plate body 8, the fixing ring 14 is provided with a magnet 15 for adsorbing the plate body 8, the fixing ring 14 is adsorbed on the plate body 8, and the filter paper 18 is pressed on the plate body 8. Due to the provision of the filter paper 18, during the working process, the solid components in the material are difficult to pass through the filter paper 18, and thus will not enter the area between the piston plate 7 and the piston ball 19, so that the area on the side of the piston plate 7 close to the piston ball 19 is kept clean, which is conducive to the smooth movement of the piston plate 7 and the piston ball 19.

[0044] The above structural arrangement can realize convenient replacement of the filter paper 18 . After a large amount of material is processed, the fixing ring 14 can be conveniently removed to replace the filter paper 18 .

[0045] Regarding the setting of the magnet 15, the magnet 15 should be set at the part where the fixing ring 14 and the plate body 8 are combined to achieve stable adsorption, and the setting position of the magnet 15 should be far away from other parts with magnetic properties to avoid action interference.

[0046] In this embodiment, the magnet 15 is disposed on a side surface of the fixing ring 14 close to the plate body 8 and is disposed in a sheet shape.

[0047] In order to realize a convenient process of replacing the filter paper 18, an operation port may be provided on the cylinder body 1, or the cylinder body 1 may be provided in a detachable split form.

[0048] In order to achieve stable cooperation between the fixing ring 14 and the plate body 8, an annular groove 10 is provided on the edge of the plate body 8, and an extended edge 16 is provided on the fixing ring 14. The extended edge 16 surrounds the annular groove 10. Through the setting of the extended edge 16 and the annular groove 10, the plate body 8 and the fixing ring 14 can be accurately aligned and the structure is stable.

[0049] In order to further improve the flexibility of the movement of the piston plate 7, the fixing ring 14 is provided with a plurality of cutting teeth 17 distributed along its edge, the cutting teeth 17 are arranged obliquely, the plate body 8 is provided with a mounting hole 11, the mounting hole 11 is provided with a bearing 12, the connecting rod 4 is connected to the bearing 12, the annular groove 10 is provided with a stop block 13, and the fixing ring 14 is provided with a stop groove matching the stop block 13. Under the above structural setting, when the piston plate 7 moves toward the near-bin end 2 of the cylinder body 1, the cutting teeth 17 cut the solid matter remaining on the inner wall of the cylinder body 1, thereby eliminating the obstruction in the movement of the piston plate 7. At the same time, since the cutting teeth 17 are arranged obliquely, when cutting, the cutting teeth 17 are subjected to a lateral reaction force, causing the fixing ring 14 to rotate. During the rotation process, the cutting performance of the cutting teeth 17 is further improved, thereby realizing the smooth movement of the piston plate 7 and the convenient cleaning process of the inner wall of the cylinder body 1.

[0050] This embodiment also provides a fermentation bin, including the above-mentioned limit feed detection device.

[0051] This embodiment also provides a kitchen waste treatment device, including the fermentation bin.
