Description
- The present invention relates to a method and an apparatus for disposing of accumulations of snow and, particularly, snow piles from parking lots of commercial buildings.
- When it snows, parking lots of commercial buildings are cleared promptly in order to ensure ease of access is maintained for customers. Snow piles are created in the parking lot, which are removed as soon as trucks can be secured to haul away the snow. As our cities become larger, the distance the snow must be hauled is increasing. More efficient ways of disposing of accumulations of snow are, therefore, required.
- It has long been recognized that snow occupies more space than its equivalent volume of water. U.S. Pat. No. 1,160,205 (Smith 1915) discloses a street cleaning apparatus for melting snow. U.S. Pat. No. 6,305,105 (Lowman 2001) discloses a more recent example of the evolution of street cleaning apparatus of such street cleaning apparatus which are capable of melting snow.
- What is required is a more efficient method and apparatus for disposing of accumulations of snow.
- According to one aspect of the present invention there is provided an apparatus for disposing of accumulations of snow which includes a receptacle which is adapted to hold and retain liquids. The receptacle has a loading mouth which is adapted to allow snow carried in a loading bucket of a front end loader to be dumped into the receptacle. Means is provided for melting accumulations of snow positioned within the receptacle, thereby converting the snow to water. A drain is provided for draining water from the receptacle.
- According to another aspect of the present invention there is provided a method for disposing of accumulations of snow. A first step involves providing an apparatus to receive snow, substantially as described above. A second step involves connecting a liquid conduit from the drain of the receptacle to an access opening to a municipal sewer system. A third step involves dumping loads of snow into the receptacle with a front end loader. A fourth step involves melting the snow within the receptacle to convert the snow to water. A fifth step involves draining the water through the drain of the receptacle and the liquid conduit for disposal in the municipal sewer system.
- The essence of the present invention is that instead of hauling the accumulations of snow for any distance, they are converted to water on site and disposed of in the municipal sewer system. This totally eliminates the cost of hauling and the delays presently being experienced in securing trucks. The receptacle is merely positioned adjacent to an access opening for the municipal sewer system. As the parking lot is cleared, the snow is dumped into the receptacle, where it melts and is disposed of directly into the municipal sewer system.
- There are various features which can be added to improve the operation of the apparatus and the method.
- Safety is always a consideration. In order to prevent children or animals from climbing into the receptacle when the receptacle is not in use, it is preferred that the loading mouth is closed by pivotally mounted access doors which pivot between an open position and a closed position. The access doors are capable of being locked in the closed position when the receptacle is not in use.
- Heat retention in order to melt the snow as quickly as possible is also a consideration. It is, therefore, preferred that the access doors be biased by biasing means into the closed position in order to retain heat. The access doors will move to the open position when the weight of a load of snow positioned on the access doors overcomes the biasing force of the biasing means.
- There are, of course, various means that can be used for heating snow within the receptacle. It is preferred that a plurality of heating pipes be positioned within the receptacle. The heating pipes are adapted to receive a circulation of hot fluids. This form of heating is more robust that other types of heating. There are various hot fluids which can be circulated, such as hot exhaust gases from a burner or hot liquids for a boiler.
- While experimenting with the most rapid manner of melting snow, it has been determined that the snow melts faster when in a bath of hot liquid. It is, therefore, preferred that the drain extend through a peripheral sidewall in spaced relation to a bottom of the receptacle. With this configuration, liquid rises in the receptacle until the drain is reached and liquid reaching the drain flows from the receptacle. This maintains a minimum liquid level within the receptacle.
- When the snow is dumped into the bath of hot liquid, it forms an ice water slush. It has been determined that the ice in the water melts faster when agitated. It is, therefore, preferred that means be provided to agitate liquids within the receptacle. Beneficial results have been obtained through the use of a circulating pump. For best results an outlet of the circulating pump is heated.
- These and other features of the invention will become more apparent from the following description in which reference is made to the appended drawings, the drawings are for the purpose of illustration only and are not intended to in any way limit the scope of the invention to the particular embodiment or embodiments shown, wherein:
- FIG. 1 is a end elevation view, in section, of an apparatus for disposing of accumulations of snow constructed in accordance with the teachings of the present invention.

Circulatingpump 46 has aninlet 48 through whichwater 34 is drawn into circulatingpump 46, and anoutlet 50 which is heated, thereby promoting the melting of ice and snow carried bywater 34 circulated by circulatingpump 46. Aflame source 47 provides heat. - Referring to FIG. 1, sand and
other debris 52 which enterreceptacle 12 along withsnow 20, can pass throughgrate 36 which supportsheating pipes 32 to settle onbottom 14 ofreceptacle 12. Adrainage outlet 54 with sealingplug 56 is provided whereby minimum level ofwater 34 along with sand anddebris 52 can be drained for maintenance and repair ofapparatus 10. - Operation:
- The operation of
apparatus 10 will now be described with reference to FIGS. 1 through 3 and in accordance with the preferred method for disposing of accumulations of snow. Referring to FIG. 1,apparatus 10, as described above is useful where hauling ofsnow 20 to a remote site for disposal is neither economical nor practical. Rather than haulingsnow 20 to a remote site for disposal,apparatus 10 can be used to meltsnow 20 for disposal at or near snow collection site. For example,apparatus 10 can be used in conjunction with existingmunicipal sewer systems 58 by connectingliquid conduit 42 fromdrain 40 ofreceptacle 12 to an access opening 60 tomunicipal sewer system 58. One or all of locking pins 28 onaccess doors 26 ofreceptacle 12 are removed to unlockaccess doors 26. Loads ofsnow 20 are dumped intoreceptacle 12 byfront end loader 24. As the weight ofsnow 20 being dumped onaccess door 26 overcomes the biasing force of spring loaded hinges 30,access door 26 pivots from a closed position to an open position to allowsnow 20 to fall throughloading mouth 18 and intoreceptacle 12. -

Becausedrain 40 extends throughperipheral sidewall 16 in spaced relation to bottom 14 ofreceptacle 12, a minimum liquid level is maintained withinreceptacle 12 which is continually heated byheating pipes 34 which are supported ongrate 36 belowdrain 40. Sand anddebris 52 which enterreceptacle 12 along withsnow 20 are either caught byscreen 44 positioned betweenliquid conduit 42 anddrain 40, or pass throughheating pipes 32 and grate 36 to settle atbottom 14 ofreceptacle 12. - A
cover 62 is provided on aremote end 64 ofliquid conduit 42 to facilitate placement ofremote end 64 ofliquid conduit 42 over access opening 60 intomunicipal sewer system 58. - Referring to FIGS. 2 and 3, circulating
pump 46 is used to agitatewater 34 withinreceptacle 12 to accelerate melting ofsnow 20 withinwater 34.Water 34 is drawn into circulatingpump 46 throughinlet 48, circulated through circulatingpump 46 and then exits throughoutlet 50 back intowater 34 so as to agitatewater 34 withinreceptacle 12. With heating ofoutlet 50 of circulatingpump 46,water 34 circulating through circulatingpump 46 is also heated before mixing withsnow 20 enteringreceptacle 12, thereby further accelerating the melting of snow withwater 34. - Referring to FIG. 1, should
apparatus 10 require maintenance or repair,water 34 along with settled sand anddebris 52 can be drained from receptacle by removing sealingplug 56 ofdrainage outlet 54. Whenapparatus 10 is not in use,access doors 26 can be locked with lockingpins 28 to prevent children or animals from climbing intoreceptacle 12. - Variations:
- Referring to FIGS. 4 through 6, there is illustrated a variation identified by
reference numeral 100. The components ofapparatus 10 and thevariation 100 detailed below will be identified by the same reference numerals as used in the description above, so that only the differences need to be identified and specifically described. - Referring to FIG. 4,
salt containers 110 can be included inreceptacle 12 for addingsalt 112 towater 34 which helps to break down the ice. Afilter membrane 114 is provided overdrain 40 to maintainsalt 112 withinreceptacle 12. - With respect to FIG. 5, in addition to
flame source 47 which operates as primary heat source, asecondary heat source 116 is provided.Secondary heat source 116 is also a flame source. Furthermore, withapparatus 100,outlet 150 of circulatingpump 46 is angled upward so that heated water is injected intoreceptacle 12 from anupper portion 152 ofreceptacle 12.Water 34 is still drawn into circulatingpump 46 throughinlet 48 and circulated through circulatingpump 46 before exiting throughoutlet 150 back intowater 34 so as to agitatewater 34 withinreceptacle 12. Referring to FIG. 6, an alternative arrangement of plurality ofheating pipes 32 is illustrated.Heating pipes 32 still receive a circulation of hot fluids to meltsnow 20 and convertsnow 20 towater 34 as illustrated in FIG. 4. Withalternative embodiment 100, in order to avoid heat loss, heating equipment can be contained withinreceptacle 12. Only elements such asprimary heat source 47 andsecondary heat source 116 remain positioned exterior toreceptacle 12 - In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded.

22. A method for disposing of accumulations of snow, comprising the steps of:
providing a receptacle which is adapted to hold and retain liquids, the receptacle having;
a loading mouth;
means for melting accumulations of snow positioned within the receptacle, thereby converting the snow to water; and
a drain for draining water from the receptacle;
connecting a liquid conduit from the drain of the receptacle to an access opening to a municipal sewer system;
dumping loads of snow into the receptacle with a front end loader;
melting the snow within the receptacle to convert the snow to water; and
draining the water through the drain of the receptacle and the liquid conduit for disposal in the municipal sewer system.
23. The method as defined in claim 22 , the drain extending through a peripheral sidewall in spaced relation to a bottom of the receptacle, such that liquid rises in the receptacle until the drain is reached and liquid reaching the drain flows from the receptacle, thereby maintaining a minimum liquid level within the receptacle.
24. The method as defined in claim 22 , including the step of agitating liquids within the receptacle to accelerate melting of snow within the liquids.
