Abstract
Description
Technical Field
[0001] This invention relates to the field of pet supplies technology, and in particular to a device for restoring the function of discarded cat litter. Background Technology
[0002] Cat litter has become an essential household item for pet cat owners, with its cleaning, deodorizing, and antibacterial functions being particularly important. Many cat litters are discarded after a single use, causing significant environmental hazards and resource waste. In reality, used cat litter is simply mixed with cat feces and urine, and its original functions can be restored with simple processing.
[0003] However, most existing cat litter boxes have limited functions, requiring manual operation for cleaning, deodorizing, and antibacterial purposes, which is time-consuming, labor-intensive, and ineffective. Therefore, developing a litter box restoration furnace suitable for community use can provide cat owners with litter box restoration services, reducing resource waste and alleviating environmental burden. Summary of the Invention
[0004] This invention aims to overcome the shortcomings of existing technologies by providing a device for restoring the functionality of discarded cat litter. The invention involves drying discarded cat litter in a drying chamber, followed by pyrolysis in a pyrolysis chamber to decompose any cat excrement mixed in with it. The result is restored cat litter that is clean, sterile, and odorless. After scenting and cooling, it becomes a usable product, reducing resource waste, lessening environmental burden, and replacing manual labor.
[0005] The technical solution adopted by the present invention to solve its technical problem is as follows: it includes a drying chamber, a pyrolysis chamber and a collection box arranged sequentially from top to bottom. The drying chamber is provided with a feed inlet. The drying chamber and the pyrolysis chamber are connected by a connecting pipe. The pyrolysis chamber is provided with a pyrolysis furnace. The collection box is provided with a sieve plate below the lower outlet of the pyrolysis chamber. A waste box is provided below the sieve plate.
[0006] Preferably, the end of the sieve plate away from the lower outlet of the pyrolysis chamber is inclined downward.
[0007] Preferably, the collection box has limiting grooves on both sides of the sieve plate, and the two sides of the sieve plate are respectively located in the limiting grooves; the collection box has a slot at the corresponding slot, and the sieve plate is connected to a reciprocating moving mechanism through the slot.
[0008] Preferably, the reciprocating movement mechanism includes a linear reciprocating motor and a connecting rod, one end of which is connected to the sieve plate and the other end is connected to the output end of the linear reciprocating motor.
[0009] Preferably, there are multiple lower outlets, which are evenly distributed around the lower side plate of the pyrolysis chamber. Multiple triangular guide blocks are provided on the upper side of the lower side plate, and the multiple triangular guide blocks are spaced apart from the lower outlets.
[0010] Preferably, a baffle mechanism is provided below the pyrolysis chamber, and the baffle mechanism includes a baffle plate located below the lower outlet.
[0011] Preferably, multiple baffles are provided, and the multiple baffles are arranged one-to-one below the lower outlet. The inner side of the baffle is provided with an inner ring, and the outer side of the baffle is provided with an outer ring. The outer ring is driven to rotate by a driver.
[0012] Preferably, a slewing bearing is provided in the middle of the lower side of the pyrolysis chamber, and the inner ring is sleeved on the slewing bearing.
[0013] Preferably, the drying chamber is equipped with a drying box, which includes a conical heating plate at the bottom and a vertically movable box body at the top, the box body being connected to an electric cylinder; the drying chamber has an inwardly inclined plate below the drying box.
[0014] Preferably, the drying chamber and the pyrolysis chamber are connected by a connecting pipe, and the connecting pipe is equipped with a shut-off valve.
[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows:
[0016] (1) The discarded cat litter is poured into the drying chamber to dry, and then enters the pyrolysis chamber to pyrolyze the cat's excrement; the processed cat litter is collected through the collection box.
[0017] (2) Small particles of waste are sieved into the waste box through the sieve plate in the collection box. The cat litter slides from the sieve plate into the collection box to obtain restored cat litter. It is clean, sterile, and odorless. After adding fragrance and cooling, it can be used directly after functional restoration, reducing resource waste, alleviating environmental burden, and replacing manual labor.
[0018] (3) The end of the sieve plate away from the lower outlet of the pyrolysis chamber is tilted downwards, so that the cat litter can slide off the sieve plate into the collection box and be collected by the operator.
[0019] (4) The screen plate moves left and right in the limiting groove through the reciprocating moving mechanism, which plays a vibrating sieve role on the pyrolyzed cat litter, making it easier to screen small particles of waste from the screen plate into the waste box, thereby improving the screening effect of the screen plate and increasing efficiency.
[0020] (5) The reciprocating movement mechanism includes a linear reciprocating motor and a connecting rod. It is simple in design and easy to maintain. When maintenance is required, the motor can be replaced. It is low in cost and easy to use.
[0021] (6) Multiple lower outlets are provided, evenly distributed around the lower side plate of the pyrolysis chamber. The cat litter after pyrolysis falls from the lower outlets. Multiple triangular guide blocks are provided on the upper side of the lower side plate. The multiple triangular guide blocks are spaced apart from the lower outlets, so that the cat litter on the lower side plate slides off the triangular guide blocks and falls into the collection box through the lower outlets, reducing the cat litter residue in the pyrolysis chamber. The litter flows down from the lower outlets around the chamber. With the setting of the pyrolysis furnace, the arrangement is reasonable and the space utilization rate is high.
[0022] (7) By setting multiple baffles one by one below the lower outlet, the lower outlet is blocked one by one, ensuring the smooth progress of the pyrolysis process. After pyrolysis, the baffles are released, and the cat litter falls into the collection box through the lower outlet. The design is reasonable and easy to use.
[0023] (8) The outer ring is driven by the driver to rotate, which in turn drives the inner ring to rotate on the slewing bearing, and the baffle plate rotates under the lower side plate, thereby blocking or opening the lower outlet and improving the performance.
[0024] (9) After the heating plate of the drying box heats the cat litter, the box is opened by the electric cylinder. Since the heating plate is conical, the cat litter falls from all sides to the outside of the drying box. It is collected in the middle by the inclined plate and flows into the pyrolysis chamber. While ensuring the drying effect, the cat litter can also flow out of the box. It is convenient to use, efficient, simple in design and low in cost.
[0025] (10) The drying chamber and the pyrolysis chamber are connected by a connecting pipe. A shut-off valve is installed on the connecting pipe to control the flow of cat litter between the drying chamber and the pyrolysis chamber. When the valve is opened, the dried cat litter flows from the drying chamber into the pyrolysis chamber. During pyrolysis, the valve is closed to reduce the overflow of hot air, save costs, and protect the environment. Attached Figure Description

[0040] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this invention. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments.
[0041] Example
[0042] The following is in conjunction with the appendix Figure 1-5 To further illustrate this invention, a waste cat litter function restoration device, such as... Figure 1 As shown,
[0043] The system includes, from top to bottom, a drying chamber 2, a pyrolysis chamber 3, and a collection box 4. The drying chamber 2 has a feed inlet 1 with a screen to remove large pieces of waste. Discarded cat litter is poured into the drying chamber 2 through the feed inlet 1 and dried (100-200℃, 10 minutes). The drying chamber 2 is connected to the pyrolysis chamber 3 via a connecting pipe 8, through which the litter enters the pyrolysis chamber 3. The pyrolysis chamber 3 contains a pyrolysis furnace 41 (300-400℃, pyrolysis for 20 minutes) to heat the cat litter. The excrement is pyrolyzed; the treated cat litter is collected through a collection box 4. The collection box 4 is equipped with a sieve plate 5 below the lower outlet 32 of the pyrolysis chamber 3, and a waste box 41 is located below the sieve plate 5. Small particles of waste enter the waste box 41 from below the sieve plate 5, and the cat litter slides from the sieve plate 5 into the collection box 4, resulting in restored cat litter that is clean, sterile, and odorless. After adding fragrance and cooling, it can be used directly after functional restoration, reducing resource waste, alleviating environmental burden, and replacing manual labor.
[0044] like Figure 3 As shown, the end of the sieve plate 5 away from the lower outlet 32 of the pyrolysis chamber 3 is inclined downward, which makes it easier for cat litter to slide off the sieve plate 5 into the collection box 4, making it convenient for operators to collect.
[0045] like Figure 3 As shown, the collection box 4 has limiting grooves 42 on both sides of the sieve plate 5, and the two sides of the sieve plate 5 are respectively located in the limiting grooves 42; the collection box 4 has a groove 43 at the corresponding groove 43, and the sieve plate 5 is connected to the reciprocating moving mechanism 6 through the groove 43.
[0046] The reciprocating moving mechanism 6 moves the screen plate 5 left and right within the limiting groove 42, which acts as a vibrating screen for the pyrolyzed cat litter. This makes it easier to screen small particles of waste from the screen plate 5 into the waste box 41, while simultaneously allowing the cat litter to slide into the collection box 4, thus improving the screening effect of the screen plate 5 and increasing efficiency.
[0047] like Figure 3 As shown, the reciprocating movement mechanism 6 includes a linear reciprocating motor 61 and a connecting rod 62. One end of the connecting rod 62 is connected to the screen plate 5, and the other end is connected to the output end of the linear reciprocating motor 61. The design is simple and easy to maintain. When maintenance is required, the motor can be replaced. The cost is low and the use is convenient.
[0048] like Figure 4 and 5 As shown, there are multiple lower outlets 32, evenly distributed around the lower side plate 33 of the pyrolysis chamber 3. The pyrolyzed cat litter falls from the lower outlets 32. Multiple triangular guide blocks 34 are provided on the upper side of the lower side plate 33. The multiple triangular guide blocks 34 are spaced apart from the lower outlets 32, so that the cat litter on the lower side plate 33 slides off the triangular guide blocks 34 and falls into the collection box 4 through the lower outlets 32, reducing the residue of cat litter in the pyrolysis chamber 3. The litter flows downward from the lower outlets 32 around the perimeter. With the setting of the pyrolysis furnace 41, the arrangement is reasonable and the space utilization rate is high.
[0049] like Figure 1 , 4 As shown in Figure 5, a baffle mechanism 7 is provided below the pyrolysis chamber 3. The baffle mechanism 7 includes baffle plates 71 located below the lower outlet 32. Multiple baffle plates 71 are provided, and the multiple baffle plates 71 are arranged one-to-one below the lower outlet 32. The lower outlet 32 is blocked by the baffle plates 71 to ensure the smooth progress of the pyrolysis process. After pyrolysis, the baffle plates 71 are released, and the cat litter falls through the lower outlet 32 into the collection box 4. The design is reasonable and easy to use.
[0050] like Figure 4 and 5 As shown, the inner side of the baffle plate 71 is provided with an inner ring 73, and the outer side of the baffle plate 71 is provided with an outer ring 74. The outer ring 74 is driven to rotate by the driver 72. The middle part of the lower side of the pyrolysis chamber 3 is provided with a slewing bearing 35, and the inner ring 73 is sleeved on the slewing bearing 35.
[0051] The outer ring 74 is driven to rotate by the driver 72, which in turn drives the inner ring 73 to rotate on the slewing bearing 35. This causes the baffle plate 71 to rotate under the lower side plate 33, thereby blocking or opening the lower outlet 32 and improving the performance.
[0052] like Figure 2 As shown, the drying chamber 2 is equipped with a drying box 21, which includes a conical heating plate 22 at the bottom and a vertically movable box body 23 at the top. The box body 23 is connected to an electric cylinder 24. The drying chamber 2 has an inwardly inclined plate 25 below the drying box 21.
[0053] The discarded cat litter first enters the drying chamber 21. After being heated by the heating plate 22, the chamber 23 is opened by the electric cylinder 24. Since the heating plate 22 is conical, the cat litter falls from all sides to the outside of the drying chamber 21. It is then collected in the middle by the inclined plate 25 and flows into the pyrolysis chamber 3. This ensures the drying effect while also allowing the cat litter to flow out of the chamber 23. It is convenient to use, highly efficient, simple in design, and low in cost.
[0054] like Figure 1 As shown, the connecting pipe 8 is equipped with a shut-off valve 81 to control the flow of cat litter between the drying chamber 2 and the pyrolysis chamber 3. When opened, the dried cat litter flows from the drying chamber 2 into the pyrolysis chamber 3. During pyrolysis, the valve is closed to reduce the leakage of hot air, save costs, and protect the environment.
