DETAILED DESCRIPTION

[0028] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] See also Figures 1 to 9 As shown, a low-temperature heat pump evaporator for preventing inner wall adhesion comprises a casing 1, a stirring rod 2 for stirring and cooling the casing 1, a rotary driver 6 for driving the stirring rod 2 to rotate, and a scraping mechanism 3 for scraping dirt on the inner wall of the casing 1 during stirring; characterized in that the scraping mechanism 3 comprises a scraper 31 and a sliding sleeve 32 for moving the scraper 31 up and down, the sliding sleeve 32 comprises a second scraper rod 33, the low-temperature heat pump evaporator further comprises a shaking mechanism 4 for moving the sliding sleeve 32 and the second scraper rod 33 up and down and resetting, and the sliding sleeve 32 and the stirring rod 2 are slidably matched via a positioning bar.

[0030] The shell of the rotary driver 6 is a motor or a servo motor, preferably a servo motor. The output shaft of the servo motor is connected to the stirring rod 2 through a coupling, so that the stirring rod 2 rotates. When the stirring rod 2 rotates, it drives the scraper 31 and the second scraper 33 installed outside it to rotate and contact the inner wall of the machine 1. The scraper 31 and the sliding sleeve 32 slide vertically along the stirring rod 2, and the sliding sleeve 32 and the stirring rod 2 are slidably matched through the positioning block. The positioning block can be cylindrical or long, preferably long, which makes the sliding sleeve 32 rotate with the rotation of the stirring rod 2. At the same time, during the rotation, the scraper 31 contacts the shaking mechanism 4, driving the second scraper 33 and the scraper 31 arranged outside the sliding sleeve 32 to shake up and down, thereby facilitating uniform scraping of the inner wall of the casing 1. The second scraper 33 has a pair and is staggered outside the sliding sleeve 32, so as to facilitate scraping of solid waste crystallized from wastewater on the inner wall of the casing 1 to avoid adhesion and difficulty in cleaning.

[0031] See also Figure 4 and Figure 5 As shown, the shaking mechanism 4 includes a positioning sleeve 41 and a return spring 42; the positioning sleeve 41 is arranged on the outside of the stirring rod 2 and below the scraper 31 and the second scraper 33, and the positioning sleeve 41 is colinear with the axis of the stirring rod 2; the return spring 42 is arranged between the sliding sleeve 32 and the positioning sleeve 41, and its upper end is fixed to the sliding sleeve 32, and its lower end is fixed to the positioning sleeve 41.

[0032] A return spring 42 is disposed on the positioning sleeve 41, and the return spring 42 is used to lift the sliding sleeve 32, so that the stirring rod 2 drives the first protrusion block 43 disposed on the upper end of the scraper 31 to intermittently contact the second protrusion block 44 when rotating. The first protrusion block 43 and the second protrusion block 44 have the same shape, and the shape diameter of the second protrusion block 44 is larger than that of the first protrusion block 43, so as to complete the up and down reciprocating movement.

[0033] See also Figure 4 and Figure 5 As shown, the shaking mechanism 4 also includes a first protrusion block 43 and a second protrusion block 44; the first protrusion block 43 is arranged at the upper end of the scraper 31, and the first protrusion block 43 is semicircular in shape; the second protrusion block 44 is arranged at the upper end of the casing 1, and the second protrusion block 44 is arranged to rotate around the axis center, and the second protrusion block 44 is in contact with the first protrusion block 43.

[0034] The first raised block 43 and the second raised block 44 may be square or semicircular, preferably semicircular. The semicircular shape may reduce the contact friction between the first raised block 43 and the second raised block 44, thereby increasing the service life of the first raised block 43 and the second raised block 44 in disguised form. The first raised block 43 and the second raised block 44 have the same shape, while the diameter of the second raised block 44 is larger than that of the first raised block 43, so that the first raised block 43 and the second raised block 44 can have a larger jitter amplitude and frequency when in contact, thereby increasing the effect of the up and down reciprocating movement.

[0035] See also Figure 6 and Figure 7 As shown, the low-temperature heat pump evaporator also includes a crushing mechanism 5 for crushing the scraped waste, and the crushing mechanism 5 includes a rotating rod 51 and a rotating plate 52; the rotating rod 51 is rotatably installed on the outside of the stirring rod 2 and is provided with a plurality of rotating plates, and the rotating rod 51 is located below the second scraping rod 33; the rotating plates 52 are arranged on the outside of the rotating rod 51 and are respectively provided with a plurality of rotating plates.

[0036] The rotating plate 52 is preferably rectangular and narrower at the bottom. When the rotating rod 51 rotates, it drives the externally installed rotating plate 52 to rotate. The rotation of the rotating plate 52 facilitates the crushing and pulverization of the scraped solid waste, thereby avoiding blockage of the waste discharge of the casing 1 due to the large shape of the solid waste after scraping and the difficulty in discharging it outside the casing 1.

[0037] See also Figure 6 and Figure 7 As shown, the rolling mechanism 5 also includes a gear 53 and a gear ring 54 ; the gear 53 is arranged at one end of the rotating rod 51 , and the gear 53 and the axis of the rotating rod 51 are colinear; the gear ring 54 is arranged in the housing 1 and meshes with the gear 53 .

[0038] When the rotating rod 51 rotates, it drives the gear 53 to contact the ring gear 54 provided in the casing 1. When in contact, the gear 53 rotates along its axis. When the gear 53 rotates, the rotating rod 51 and the rotating plate 52 rotate synchronously, thereby achieving the effect of crushing and lifting the solid waste.

[0039] See also Figure 6 and Figure 7 As shown, the rolling mechanism 5 also includes a material placing plate 55 ; the material placing plate 55 is arranged outside the stirring rod 2 , the material placing plate 55 is located below the rotating rod 51 , and the upper end of the material placing plate 55 is in contact with the rotating plate 52 .

[0040] The placing plate 55 is located at the lower part of the rotating plate 52. The placing plate 55 can cause solid waste to accumulate and stay on the placing plate 55. When the rotating plate 52 rotates, the solid waste staying above the placing plate 55 can be crushed and pulverized. A plurality of circular through holes are provided on the placing plate 55. The through holes can be square or polygonal, preferably circular. The circular shape is used for the solid waste to pass through after being crushed for replacement, so as to avoid the solid waste after being crushed from staying and accumulating above the placing plate 55.

[0041] See also Figure 8 and Fig. 9 As shown, the low-temperature heat pump evaporator also includes a spiral blade 56 and a rotating plate 57; the spiral blade 56 is arranged outside the stirring rod 2 and is located below the material placement plate 55; the rotating plate 57 is installed outside the stirring rod 2 and is coaxially fixed with the stirring rod 2.

[0042] The spiral piece 56 rotates along with the rotation of the stirring rod 2, and the crushed solid waste on the placing plate 55 falls onto the spiral piece 56 after passing through the circular hole. When the spiral piece 56 rotates, the solid waste can be evenly rotated and dropped until it falls on the bottom of the casing 1, and the rotating plate 57 is driven to rotate when the stirring rod 2 rotates, so that the rotating plate 57 can rotate to the bottom end of the casing 1, thereby preventing the solid waste from accumulating at the discharge port at the bottom end of the casing 1.

[0043] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
