[0021] The following is combined with Figure 1-2 This application is described in further detail.

[0022] The present application embodiment discloses a stirring paddle for improving the heat exchange efficiency of a heating tank for extracting oil from whole pulp of kitchen waste. Figure 1 In this embodiment, the stirring paddle for improving the heat exchange efficiency of the whole pulp oil extraction heating tank of kitchen waste comprises a stirring shaft 1, a propeller blade 2, a stopper 21, a locking strip 3 and a locking member. The propeller blade 2 is spirally wound on the outer side of the shaft of the stirring shaft 1; a plurality of stoppers 21 are provided, and the plurality of stoppers 21 are staggeredly installed on the two inner sides of the propeller blade 2, specifically, five stoppers 21 are provided on one side, and four stoppers 21 are provided on the other side.

[0023] Two sliding grooves 11 are symmetrically opened on the outer wall of the stirring shaft 1. The two sliding grooves 11 are vertically located on the outer side of the stirring shaft 1 in the length direction, and the limit seats 21 respectively cooperate with the two sliding grooves 11, so that the propeller blades 2 are slidably installed on the stirring shaft 1 through the limit seats 21.

[0024] At the same time, a number of limit grooves 12 are staggered on the two outer side walls of the stirring shaft 1, and the limit grooves 12 are respectively connected with the two sliding grooves 11. Specifically, in this embodiment, one sliding groove 11 is connected with five limit grooves 12, and the other sliding groove 11 is connected with four limit grooves 12. The limit grooves 12 on the same side are arranged parallel to each other, and the limit grooves 12 are respectively matched with the limit seats 21; when the propeller blade 2 is rotated, the propeller blade 2 drives the limit seat 21 to slide from the sliding groove 11 into the limit groove 12, thereby limiting the propeller blade 2 on the stirring shaft 1.

[0025] In addition, two locking strips 3 are provided, and the two locking strips 3 are respectively slidably installed in the two sliding grooves 11 to firmly limit the limit seats 21 in the limit grooves 12; at the same time, a plurality of locking members are provided, and the plurality of locking members are respectively arranged between the locking strips 3 and the stirring shaft 1, so as to further fasten the locking strips 3 in the sliding grooves 11 of the stirring shaft 1, so as to effectively block and firmly install the limit seats 21, thereby realizing the firm installation of the propeller blades 2 on the stirring shaft 1.

[0026] Specifically, refer to Figure 1 In the present embodiment, the locking member is a locking bolt 4, which is arranged between the locking strip 3 and the agitator shaft 1, and a plurality of first threaded holes 31 are opened on the locking strip 3, and a plurality of second threaded holes 13 are opened on the agitator shaft 1, and the second threaded holes 13 are located in the sliding groove 11; when the locking strip 3 is installed in the sliding groove 11, the first threaded holes 31 correspond to the second threaded holes 13 one by one respectively; and the locking bolt 4 is threadedly connected with the first threaded hole 31 and the second threaded hole 13 at the same time, and the locking strip 3 can be firmly locked in the sliding groove 11 by screwing the locking bolt 4 into the first threaded hole 31 and the second threaded hole 13 in turn.

[0027] Therefore, by setting the sliding groove 11, the limit groove 12, the limit seat 21, the locking strip 3 and the locking piece in a structure that cooperates with each other, not only can the propeller blade 2 be firmly installed on the shaft body of the stirring shaft 1, but the propeller blade 2 can also be quickly removed from the shaft body of the stirring shaft 1, thereby achieving the effect of separation and single replacement, thereby reducing costs and reducing waste of resources.

[0028] Preferably, in this embodiment, sealing layers are fixedly installed on the groove walls around the sliding groove 11 and the limiting groove 12, and these sealing layers cooperate with the limiting seat 21 and the locking strip 3 respectively. By setting the sealing layers, an effective sealing and waterproof effect can be achieved, thereby reducing the entry of moisture into the sliding groove 11 and the limiting groove 12 during stirring.

[0029] In addition, refer to Figure 1 In the present embodiment, a notch 32 is provided on the inner side of one end of the locking strip 3 extending into the bottom of the sliding groove 11, and the notch 32 is communicated with the sliding groove 11 to form a sliding cavity, in which an elastic component is provided, and the elastic component cooperates with the locking strip 3 to elastically support the locking strip 3.

[0030] Specifically, the elastic component includes an elastic block 5 and an elastic member. The elastic block 5 is slidably mounted on the bottom of the sliding groove 11, and the elastic block 5 is located in the sliding cavity; the elastic member is arranged between the elastic block 5 and the bottom of the sliding groove 11, and more specifically, the elastic member is a spring 6, one end of which is connected to the bottom side of the elastic block 5, and the other end of which is connected to the bottom of the sliding groove 11. Under the elastic action of the spring 6, the elastic block 5 is pressed against the top wall of the notch 32 of the locking strip 3.

[0031] When the locking bolt 4 is twisted out, the locking strip 3 is unlocked, and then the elastic block 5 is pressed upward under the elastic return action of the spring 6, so that the elastic block 5 presses the locking strip 3 upward, so that the locking strip 3 slides upward along the sliding groove 11, and the top of the locking strip 3 slides out of the top of the sliding groove 11, so that it is convenient to take the locking strip 3 out of the sliding groove 11 to release the restriction of the limit seat 21, and then it is convenient to rotate and remove the propeller blade 2 from the stirring shaft 1.

[0032] Better, refer to Figure 1 and Figure 2 In this embodiment, lifting grooves 33 are symmetrically provided on both sides of the top of the locking strip 3. The lifting grooves 33 cooperate with the fingers of the dismantling personnel. When the top of the locking strip 3 slides out of the top of the sliding groove 11, the dismantling personnel can easily remove the entire locking strip 3 from the sliding groove 11 through the lifting grooves 33. A plurality of protective convex particles 34 are installed in the lifting grooves 33, and these protective convex particles 34 can effectively prevent slipping.

[0033] The implementation principle of an agitator blade for improving the heat exchange efficiency of a whole slurry oil extraction heating tank for kitchen waste in an embodiment of the present application is as follows: when the propeller blade 2 needs to be installed on the agitator shaft 1, first align the limit seat 21 on the propeller blade 2 with the sliding groove 11, and then slide it into the sliding groove 11, and then rotate the propeller blade 2 to make the limit seat 21 slide into the limit groove 12, and then slide the locking strip 3 into the sliding groove 11 to squeeze the elastic block 5 downward so that the spring 6 elastically contracts, and then twist the locking bolts 4 into the first threaded hole 31 and the second threaded hole 13 in turn, so that the locking strip 3 can be firmly locked in the sliding groove 11, thereby achieving a firm installation of the propeller blade 2 on the shaft body of the agitator shaft 1.

[0034] When the propeller blade 2 needs to be removed from the stirring shaft 1, the locking bolts 4 are first twisted out of the second threaded holes 13 and the first threaded holes 31 to unlock the locking strip 3, and then the elastic block 5 is pressed against the top wall of the notch 32 of the locking strip 3 under the elastic return action of the spring 6, so that the locking strip 3 slides upward along the sliding groove 11, so that the top of the locking strip 3 slides out of the top of the sliding groove 11, so that it is convenient to take the locking strip 3 out of the sliding groove 11 to release the restriction of the limit seat 21, and then it is convenient to rotate and remove the propeller blade 2 from the stirring shaft 1.
