Referring to fig. 4 and 7, the embodiment of the present invention is different from embodiment 1 in that: the pushing assembly 202 includes a fixing plate 2021 and an air bag 2022.
In the embodiment of the invention, a fixing plate 2021 is fixedly installed at the position of the left part of the bottom end of the inner wall of the shell 201, the appearance of the fixing plate 2021 is in the shape of a reciprocal 7 on a longitudinal section, the outer surface of the right side of the fixing plate 2021 is attached to the outer surface of the left side of the storage tank 2012, and the left part of the bottom end of the fixing plate 2021 is spaced from the left wall of the shell 201;
an air bag 2022 is embedded between the inner wall of the fixing plate 2021 and the lower end of the left wall of the shell 201;
the fixing plate 2021 has an inverted figure 7 shape in a longitudinal section, so that after the fixing plate 2021 and the housing 201 together limit the air bag 2022, the air bag 2022 can be inflated and expanded upwards in time when the left side of the housing 201 protrudes inwards to push the material guiding assembly 203 to move.
According to the stop valve with the anti-blocking mechanism, the pushing assembly 202 is arranged, and by utilizing the negative pressure principle, when the residual water in the recovery box 1 is not frozen, the air bag 2022 of the pushing assembly 202 is in a natural expansion and undeformed state; however, when the remaining water in the recycling bin 1 freezes, the state is gradually broken, that is, as described above, the outer side of the casing 201 deforms convexly towards the inside of the casing 101, and due to the limitation of the fixing plate 2021 of the pushing assembly 202 and the left side of the casing 201 on the air bag 2022, under the action of the negative pressure principle, the left side of the casing 201 presses and moves the air in the air bag 2022 to surge towards the top end of the air bag 2022, so that the air bag 2022 expands upwards to deform, so as to push the subsequent material guiding assembly 203 to move to release the heating material to generate heat, thereby pushing the heating, and facilitating the prevention of the freezing inside of the recycling bin 1.
Example 3
Referring to fig. 4 and 8, the embodiment of the present invention is different from embodiment 1 in that: the material guide assembly 203 includes a rotating shaft 2031, a balancing tank 2032 and quicklime powder.
In the embodiment of the present invention, a rotating shaft 2031 is rotatably mounted at an upper position of the center of the interior of the housing 201 in the front-rear horizontal direction, the rotating shaft 2031 is disposed at a position right above the top of the right end of the fixing plate 2021, an inclined plate 20311 is fixedly mounted on the outer surface of the right side of the rotating shaft 2031 in an inclined manner, a bracket 20312 is fixedly mounted at a position of the left end and the right end of the top of the rotating shaft 20311 in the vertical direction, and the bracket 20312 is in a rectangular frame shape penetrating through the left and right;
the sloping plate 20311 is arranged to prevent quicklime powder from sliding to the right end of the balance plate 2032 through the bottom end of the sloping plate 20311 under normal conditions; the right and left rectangular parallelepiped frame-shaped holder 20312 supports the balance groove 2032 together with the sloping plate 20311, and is arranged to facilitate the quicklime powder to slide from the holder 20312 to the right end of the balance plate 2032.
In the embodiment of the present invention, a balance groove 2032 is fixedly installed between the bottom end of the inclined plate 20311 and the top end of the bracket 20312, the appearance of the balance groove 2032 is hollow inside and is left closed and right opened, the balance groove 2032 is divided into a left cavity and a right cavity by the rotating shaft 2031, the balance groove 2032 is in a horizontal static state under normal conditions, the left outer surface of the balance groove 2032 is spaced from the left wall of the housing 201, and the tail of the right end of the balance groove 2032 is erected at the upper end of the right wall of the housing 201 under normal conditions;
the outward appearance of compensating groove 2032 here is established to inside cavity, left side and is closed right side and open the form, is for being convenient for utilize lever principle, when not freezing store the lime powder rather than interior left end, treat to freeze the back and shift to the inside right-hand member with the lime powder to take place clockwise rotation, thereby derive the lime powder from the right-hand member export and heat in storage tank 2012 after mixing with the clear water contact, in order to melt ice.
In the embodiment of the invention, quick lime powder is preloaded at the left end position in the balance groove 2032, and the preloaded amount of each quick lime powder is lower than the height between the top end of the rotating shaft 2031 and the bottom wall of the balance groove 2032 under normal conditions;
here, the height of the pre-loaded amount of the quicklime powder is normally lower than the height between the top end of the rotating shaft 2031 and the bottom wall of the balancing groove 2032, so as to prevent the quicklime powder from overflowing from the bracket 20312 to the right end of the balancing plate 2032 when the ice is not frozen and causing the waste of the quicklime powder.
According to the stop valve with the blocking prevention mechanism, the material guide assembly 203 is arranged, and by utilizing the lever principle, when the residual water in the recovery box 1 is not frozen, the balance groove 2032 of the material guide assembly 203 is in a horizontal static state, the tail part of the right end of the balance groove 2032 is in a state of the upper end position of the right wall of the lap-over shell 201, and the quicklime powder in the balance groove 2032 is placed in the balance groove 2032, and the left end of the balance groove 2032 is not overflowed to the right end; however, when the remaining water in the recovery tank 1 freezes, the state is gradually broken, that is, after the air bag 2022 expands upwards and deforms, the top end of the air bag 2022 will push against the left end of the bottom side of the equilibrium groove 2032, and under the action of the lever principle, the equilibrium groove 2032 rotates clockwise, so that the quicklime powder in the equilibrium groove 2032 flows out to the right end of the equilibrium groove 2032 through the bracket 20312 in the equilibrium groove 2032; while the balance groove 2032 is in the pivoted, its right-hand member afterbody can leave the right wall upper end position of casing 201 gradually, produces the interval between the two to fall into the quick lime powder in the balance groove 2032 to inside the stock chest 2012 through this interval, produce a large amount of heats after taking place the contact with the clear water in the stock chest 2012, so in order to realize the derivation to the material that heats, be convenient for prevent that the collection box 1 is inside to freeze.
