[0011] The rust removal box is provided with a bracket, and the length of the legs of the bracket is longer than the length of the conduit located outside the rust removal box.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The rust removal device disclosed in the present application can remove rust from mold steel with a long length, thereby ensuring the integrity of the mold steel, so that it can be applied to mold steel with a long length during subsequent deep processing without damaging the structure and strength of the mold steel. At the same time, although the rust removal device of the present application is mainly for mold steel with a long length, it also has the rust removal function for mold steel of other structural shapes, so it has strong applicability.

[0014] (2) At the same time, the present application adopts a rust removal sand method to remove rust from the mold steel surface. Compared with the traditional grinding and rust removal method, its rust removal ability is stronger, and the rust removal ability at the corners of the special-shaped structure mold steel is better, which can effectively prevent dead corners. Furthermore, in order to make the rust removal of the mold steel more thorough, the rust removal mechanism set in the present application can be set to multiple rust removal mechanisms arranged equidistantly, so that the mold steel passes through in turn, thereby enhancing the rust removal function.

[0015] (3) The rust removal mechanism of the present application is of annular design, so when the mold steel enters the rust removal mechanism, it is completely wrapped by the rust removal mechanism to eliminate dead corners. A plurality of nozzles are arranged on the spray ring of the annular structure. The installation angles of the nozzles make the injection points converge at the same center, so that the mold steel can completely act on the surface of the mold steel when it passes through. The rust removal mechanism is placed in the rust removal box, so the rust removal sand after rust removal will fall to the bottom of the rust removal box and be re-transported to the conduit through the extraction mechanism. The conduit and the connecting pipes on both sides of the spray ring are connected to form a recycling method. In order to prevent the residual rust removal sand from adhering to the surface of the mold steel after rust removal, the present application provides a discharge channel on the discharge port of the rust removal box. A fan is provided on the upper surface of the channel to blow on the mold surface to blow off the residual rust removal sand. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of rust removal mechanisms 200 are arranged in the rust removal box 100 and between the guide rollers 104. The rust removal mechanism 200 includes a spray ring 201 and a nozzle 201b. The mold steel enters the rust removal box from the feed port. The mold steel is driven to move toward the discharge port by multiple guide rollers 104 in 100. During this process, when the mold steel passes through the spray ring 201, rust removal sand is sprayed through the nozzle 201b on the spray ring 201 to remove rust on the surface of the mold steel. The rust removal mechanism 200 is annular in design. Therefore, when the mold steel enters the rust removal mechanism 200, it is completely wrapped by the rust removal mechanism to eliminate dead corners. Multiple nozzles 201b are arranged on the spray ring 201 with an annular structure. The installation angle of each nozzle 201b makes the convergence center of the injection point coincide, so that when the mold steel passes through, it can fully act on the surface of the mold steel.

[0027] exist Figure 3-5 In order to facilitate the passage of rust removal sand, the spray ring 201 is designed to be a hollow structure, and fixed blocks 201a are integrally connected on both sides of the spray ring 201. The spray ring 201 is fixed in the rust removal box 100 by the fixed blocks 201a. A connecting pipe 201a-1 is passed through the outer surface of the fixed block 201a on one side to communicate with the spray ring 201, and multiple connecting pipes 201a-1 are connected to each other. A conduit 201c is installed at the connection. An extraction pump is installed at the end of the conduit 201c and is placed at the bottom of the rust removal box 100. The extraction pump extracts the rust removal sand at the bottom of the rust removal box 100 into the conduit 201c, and the rust removal sand is evenly transported to each connecting pipe 201a-1 through the conduit 201c.

[0028] exist Figure 1-3In the process, considering the long length of the mold steel, in order to save effort and convenience when feeding it into the rust removal box 100, a feed support plate 101 is welded at the feed port, and the bottom of the feed support plate 101 is flush with the lower eaves of the feed port, so that the mold steel can enter the rust removal box 100 along the feed support plate 101. In this process, the feed support plate 101 bears part of the weight of the mold steel, and a discharge channel 102 is provided on the outer sleeve of the discharge port. The bottom of the discharge channel 102 is flush with the lower eaves of the discharge port. The discharge channel 102 bears part of the weight of the mold steel, which is convenient for the mold steel to remain stable when discharging. Furthermore, in order to prevent splashing due to the collision of sand and mold steel during sand blasting, curtains 102b are nailed at the feed port and the discharge port. The curtain 102b blocks the inlet and outlet to prevent rust-removing sand from flying out through the inlet and outlet. In order to prevent residual rust-removing sand from adhering to the surface of the mold steel after rust removal, a fan 102a is installed on the upper surface of the discharge channel 102. The fan 102a has a built-in fan to blow and clean the surface of the mold steel after rust removal. In order to better collect the rust-removing sand and have sufficient space for rust removal, the rust removal box 100 in the present application is composed of two parts, the upper part is a rectangular structure, and the lower part is a bucket-shaped structure. The extraction pump is placed in the lower part of the bucket-shaped structure. A bracket 101 is provided on the rust removal box 100. The length of the bracket leg is longer than the length of the conduit 201c located outside the rust removal box 100, thereby avoiding the conduit 201c from contacting the ground and causing wear.
