JPH07123896A - Device for cleaning sand and vehicle loading sand-cleaning device thereon - Google Patents

Abstract

PURPOSE:To provide a device used for cleaning sand in the sand box of a park, etc., by heating and burning the sand sucked up with a suction device, sieving the treated sand to remove dangerous matters such as nails, and subsequently discharging the cleaned sand. CONSTITUTION:The sand of a sand box 14, etc., sucked up with a suction device 7, heated and burnt with a heater 8, and subsequently sieved with a sieving device 9 to remove dangerous matters such as broken glass pieces, the retained caps of empty cans, or nails. The cleaned sand is discharged on the original sand box 14, etc., with a discharging device 10. When the cleaning device 11 is loaded on a vehicle 6, carried to the sand box, etc., and subsequently subjected to the cleaning treatment, the sand can easily be treated without requiring another facility for the treatment.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention purifies and reuses sand in sandboxes contaminated with feces and microbes of dogs and cats, and also containing glass debris, lids of empty cans, dangerous substances such as nails. The present invention relates to a sand purifying device and a vehicle equipped with the sand purifying device.

[0002]

2. Description of the Related Art Feces left by dogs and cats, shards of glass discarded by careless humans, lids of empty cans, nails, and other dangerous materials are rarely mixed in the sand in the park sandbox. Therefore, not only is there a risk that infants who touch the sand directly with their hands may get infected with the bacillus and may be injured,
Since there was also a mental health problem of making users uncomfortable, the surrounding citizens have made strong demands for improvement, saying that it is not possible for children to play with peace of mind, and that local governments Although it has been discussed in the parliament, the current situation is that even if one tries to actually manage the sand in the sandbox, there is no suitable means, and it is difficult to deal with it, and he is holding back.

[0003]

In view of the above situation, the present invention purifies dirty sand in a sandbox in a park,
It is an object of the present invention to provide a reusable sand purification device and a vehicle equipped with the sand purification device.

[0004]

In order to achieve the above object, a sand purifying device according to the present invention comprises a suction device for sucking sand, a heating device for heating the sucked sand, and a burned sand for sieving. , Glass shards, lids of empty cans, sorting devices for removing dangerous substances such as nails, and purified sand is discharged by a discharging device. Further, according to the vehicle according to the present invention, a suction device for sucking sand such as a sandbox, a heating device for heating the sucked sand, the burned sand is sifted, glass fragments, a lid of an empty can, a nail, etc. It is equipped with a sorting device that removes dangerous substances and a discharge device that discharges purified sand.

[0005]

According to the sand purification apparatus for a sandbox according to the present invention, first, the sand in the sandbox is sucked into the processing chamber by the suction apparatus and heated by the heating apparatus to incinerate feces of dogs and cats, microorganisms, etc. A screening device is used to screen and remove dangerous substances such as broken glass, lids of empty cans, and nails, and the sand purified by this is discharged by a discharging device. Further, according to the vehicle of the present invention, a suction device for sucking sand, a heating device for heating the sucked sand, a burned sand is sifted,
Since it is equipped with a shard of glass, a lid of an empty can, a sorting device for removing dangerous substances such as nails, and a discharge device for discharging purified sand, the above-mentioned purification work is carried out directly in the sandbox by a vehicle, It can be carried out and therefore does not require a facility for treatment and does not require a troublesome transportation work of sand to a treatment plant away from the park, so that the treatment can be carried out quickly.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A sand purifier and a vehicle equipped with the sand purifier according to the present invention will be described below with reference to an embodiment shown in the accompanying drawings. The sand purification device 1 according to the present invention is
A suction device 2 for sucking sand, a heating device 3 for heating the sucked sand, a burned sand is sifted, and a glass fragment,
A lid of an empty can, a sorting device 4 for removing dangerous substances such as nails, and a device 5 for discharging purified sand. Further, according to the vehicle 6 according to the present invention, the suction device 7 for sucking sand, the heating device 8 for heating the sucked sand with hot air, the sorting device 9 for filtering the burned sand with a sieve, and the purified sand are provided. Sand purification device 11 consisting of discharging device 10
It is equipped with. In the figure, 12 and 13 are heat insulating plates, and 14 is a sandbox. The suction device, the heating device, the sorting device, and the discharging device shown in the above embodiments may be any means as long as they have a suction function, a heating function, a sorting function, and a discharging function. The device and the discharging device may suck or discharge by a hose using a vacuum pump, and the heating device may send the heat of the heater by a blower. Moreover, you may add a cooling device for cooling the heat-processed sand as needed.

[0007]

As described above, according to the sand purifier and the vehicle equipped with the sand purifier according to the present invention, a large amount of sand can be obtained by automatically purifying dirty sand in the park. In addition to the remarkable effect that it can be purified in a short time, it can incinerate feces and microorganisms of dogs and cats, and can also remove glass shards, lids of empty cans, nails and other dangerous substances, so it is safe It also has the excellent effect of reusing clean sand. Also, if you use a vehicle equipped with a sand purification device, you can go to the sandbox directly and quickly implement it,
Therefore, there is no need for a facility for treatment and there is no need for troublesome transportation work of sand to a treatment plant away from the park, which is advantageous in that it can be easily introduced into each local government.
