Description

Technical Field

[0001] The present invention relates to the technical field of kitchen waste treatment, and particularly relates to an extreme feeding detection device, a fermentation tank, and a kitchen waste treatment equipment. Background Art

[0002] Due to the high temperature, high humidity, high oil content, and large dust in the horizontal fermentation tank, and there is a stirring shaft in the tank, there is no dead angle stirring in the tank. The environment for installing sensors is harsh, the equipment runs with large vibrations, and the material state in the tank will present different material states in different treatment cycles (fluid or semi-fluid in the early stage, and powdery 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 paddle will affect the detection of the sensor and is prone to misjudgment;

[0004] 2. It is not waterproof or the sensor is prone to water or oil hanging, which affects the detection accuracy and is prone to failure;

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

[0006] 4. The stirring paddle is prone to cause irreversible damage to the sensor;

[0007] 5. Using radar or infrared material sensors has high costs, and they cannot be hung with oil, water, or contaminated with dust, and are prone to interference from the stirring paddle.

[0008] In view of this, an extreme feeding detection device, a fermentation tank, and a kitchen waste treatment equipment are specifically proposed. Summary of the Invention

[0009] The purpose of the present invention is to provide an extreme feeding detection device, a fermentation tank, and a kitchen waste treatment equipment to solve the problems pointed out in the background art.

[0010] The above technical purpose of the present invention is achieved through the following technical solutions:

[0011] An extreme feeding 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 set to be tubular, the cylinder body has a near-tank end and a far-tank end, the near-tank end is connected to the side of the fermentation tank body, the piston plate is arranged in the cylinder body and is 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-tank 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-tank end of the cylinder body. The piston ball is of 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, and 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. As a result, the spring in the cylinder body returns to its original shape, generating an outward thrust. This causes the piston plate to move from the far end of the cylinder body to the near end inside the cylinder body under the push of the restored spring force. Eventually, the connecting rod moves away from the alarm trigger device. After receiving the information that the slider has moved away, the alarm trigger device generates an alarm signal, triggering the alarm to start an alarm reminder and providing information to the waste disposal center.

[0023] With the setup of the extreme feeding detection device of the present invention, the following technical effects can be achieved:

[0024] 1. The device can check the detection of material addition and discharge in the fermentation bin. The device can be flexibly installed, and the installation position can be customized according to the positions that need to be detected in the fermentation bin.

[0025] 2. The device is equipped with an alarm trigger device and an alarm, which can automatically sense the position of the material in the fermentation bin without the need for on-site personnel.

[0026] 3. The device is equipped with a piston ball, which can not only sense and detect hard materials but also has an induction alarm function for liquid materials with high moisture content. BRIEF DESCRIPTION OF THE DRAWINGS

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 trigger device 5 is set as a travel switch.

[0040] To achieve installation, a limit feeding detection device of this embodiment further includes a mounting plate 21. An opening 22 and a plurality of fixing through holes 23 are provided on the mounting plate 21. 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 fixation. By passing bolts through the fixing through holes 23, the mounting plate 21 is mounted on the side wall of the fermentation bin.

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

[0042] To achieve the installation of the sliding seat and the alarm trigger device 5, a limit feeding detection device of this embodiment further includes a carrier plate 25. The sliding 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 is connected to the plate body 8. A plurality of water permeable holes 9 are provided on the plate surface of the plate body 8. A magnet 15 for adsorbing the plate body 8 is provided on the fixing ring 14. The fixing ring 14 is adsorbed on the plate body 8 and presses the filter paper 18 on the plate body 8. Due to the setting of the filter paper 18, during the working process, the solid components in the material are difficult to pass through the filter paper 18, so they will not enter the area between the piston plate 7 and the piston ball 19, keeping the area on the side of the piston plate 7 close to the piston ball 19 clean, which is beneficial to the smooth movement of the piston plate 7 and the piston ball 19.

[0044] Through the above structural settings, the convenient replacement of the filter paper 18 can be realized. 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 combined part of the fixing ring 14 and the plate body 8 to achieve stable adsorption, and the setting position of the magnet 15 should be far away from other magnetically - property components to avoid action interference.

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

[0047] To achieve a convenient process of replacing the filter paper 18, an operation opening can be provided on the cylinder body 1, or the cylinder body 1 can be set as a detachable split - type form.

[0048] To achieve a stable fit 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 extension edge 16 is provided on the fixing ring 14. The extension edge 16 surrounds the annular groove 10. Through the arrangement of the extension edge 16 and the annular groove 10, the plate body 8 and the fixing ring 14 can be accurately aligned and the structure is made stable.

[0049] To further improve the flexibility of the movement of the piston plate 7, a plurality of cutting teeth 17 are provided on the fixing ring 14 along its edge. The cutting teeth 17 are inclined. An installation hole 11 is provided in the plate body 8, a bearing 12 is provided in the installation hole 11, the connecting rod 4 is connected to the bearing 12, a limiting block 13 is provided in the annular groove 10, and a limiting groove for cooperating with the limiting block 13 is provided on the fixing ring 14. With the above structural arrangement, when the piston plate 7 moves towards the near bin end 2 of the cylinder block 1, the cutting teeth 17 cut the solid substances remaining on the inner wall of the cylinder block 1, thereby eliminating the obstacles during the movement of the piston plate 7. At the same time, since the cutting teeth 17 are inclined, when cutting, the cutting teeth 17 receive 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 realizing the convenient cleaning process of the inner wall of the cylinder block 1.

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

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